what output are you getting for this code?

show us your code!

Sorry, I missed one more thing;
second for loop should have
oRange.Value2 = itemDataGridView.Rows[i].Cells[j].Value;

No! I didn't mean you add to the namespace it self, use the alias name i.e.

oRange = oSheet.Cells[1, j + 1] as Excel_12.Range;

oRange = oSheet.Cells[i + 2, j + 1] as Excel_12.Range;

ok, then give the full namespace Excel_12.Range.

First you write a message;
Second you send it to the user.

Dumb question is most likely receive dumb answer.

First, I am bit surprise to see, this information is parsed as block of string, in which some values are separated by space and some are by CR. Also there is no identification of what is what. For example the PNR code, in your regex you are looking for 6 characters starts with a space and ends with two spaces, so if the string block has another parameter with 6 characters separated by two spaces, then its doom to failure.

thes block of strings need intermediate steps to chunk them out as headers "from start to the beginning of passenger number '1.', second the passengers and their flight details such as start from '1.' and end on 'FXR', then the third chunk the itinerary and the re booking part.

Once you split the string block into three parts then it will be easier for you to do the conditional checks as you needed.

this will give you the permutation of all values in the input1 array.

string[] input1 = new string[] { "a", "b", "c", "d" };
var result = from a in myString from b in myString where a != b select a + b;
string[] array = result.ToArray();

I haven't figured out how remove the repetition yet.

What you need is a permutation algorithm and assign the value for each set.

Why are you going through the foreach loop but selecting only the first item in the updateStatus collection?

Is the View property set to "Details"?
And the HeaderStyle property set to either "Clickable" or NonClickable" ?

Again this is an assumption you are making, neither of us know what is the authors requirement.
Any how, In my answer I was providing an alternative option, that instead of allowing the user to enter some inputs and validating them at the end, why not stop the user from entering invalid inputs. If there is a requirement to have the '+' in particular location, it can also be verified in the key pressed event; that is up to the developer.
It is just an alternative way of approaching this issue.

Are you sure?

Why not? The author did not specifically say that there should be only one + symbol and the location that the symbol.

you could stop the user from typing anything other than number or + in the text box if you want, this will eliminate need for regex at later stage.

FindControl method takes string as argument, so the ("ddlvtype1" + i+1) automatically converted to string. The addition of i +1 not the type int in place of string are not the problem. The problem is I think is that "ddlvtype1" should not have the "1" at the end. Adding a number to the variable will make the control names start from 11, i.e. if i = 0, ("ddlvtype1" + i+1) = "ddlvtype11" not "ddlvtype1" what it should have been.

Display units not at all contribute to the performance of the machine it is connected to. The Graphic card in the machine contribute the performance of the machine, and also the Graphic card which decides (firmware) how many and what type of display units to support.

The line of code "if (buffer.Count() == bytes)" is redundant because you just created the buffer with size of bytes, it will always be true. What you should be checking is
if (bytes > 5)
So that if the bytes read is less than 5 you will not try to access that index.

Second, the DataReceived event sent out when there is some data in the serial buffer, this doesn't mean that the data is full packet i.e. in your case the full 8 bytes of data. So you have to keep the received data separate until you got all the 8 bytes, then process them.

Are you sure you should be looking for control ("ddlvehicles1" + i+1)?
shouldn't this be ("ddlvehicles" + i+1), without the number at the end, because you are adding the number using the for loop.
if i = 0;
("ddlvehicles1" + i+1) = "ddlvehicles11" and
("ddlvehicles" + i+1) = "ddlvehicles1".

Can you post any of your code fragments?

You make a connection to the database using appropriate database driver, once the connection is established, insert, update, delete, etc. using queries.

what type of database i.e sql, My Sql, Sql light, MS access, oracle, etc.?
Although I can guess what database you will be using in a windows phone app, I would rather you tell us.

How much do you know about programming in C# and database? answer to this question may help us to guide you in the appropriate path.

What do you mean by the term "Monitor" is this an application monitoring the performance of CPU? or is this refer to "Display Unit"?

How this would work?

you can always use a label instead of tool tip or context menu. The label can displayed your selected text as well as it can take mouse click event.

So
Label lbl = new Label();
lbl.width = 100;
lbl.Height = 50;
lbl.Location = new Point(richTextBox1.Location.X + 100, richTextBox1.Location.Y + 100);
lbl.Click += button_Click;
lbl.Visible = false;
lbl.SentToBack();
private void richTextBox1_SelectionChanged(object sender, EventArgs e)
{
if (richTextBox1.SelectedText.Length > 0)
{
// do your football comparison
// then
if (football)
{
lbl.Text = "this is football";
lbl.Visible = true;
lbl.BringToFront();
}
}
}

void button_Click(object sender, RoutedEventArgs e)
{
lbl.Visible = false;
lbl.SentToBack();
richTextBox1.Text = richTextBox1.Text.Replace("football", "This is football"); // set or append the text here.

// also get the index and the length of "this is football", change the font if you want.
}

Remove all GUIDs and "ComVisible" attributes from the class, then switch the [assembly: ComVisible(true)] attribute in the AssemblyInfo-File to 'true'

In VS in the "Debug" menu, click on the "Exceptions" sub menu item (or use the short cut key Ctrl+D,E) to open the exception window.

In the exception Window Click on the "Find" button, this will open a search dialog. In the search dialog type "ComObject" and click on the "Ok" button to search for that exception.

The search will highlight the "System.Runtime.InteropServices.ComObjectInUseException" under the tree of "System.RuntimeInteropeServices". Click on the check box "System.Runtime.InteropServies" this will enable all child exceptions. Click ok to close the Exception window, and run the app again. This time the VS will break at the point when the exception occurs. When it breaks look at the code to see what is going wrong. If you cannot see any bug, post the code here.

Did you run your app in the Visual studio, or on its own?

you still haven't optimized your code as I mentioned earlier.

Stick a break point at the line CheckBox chk=(CheckBox)row.Cells[3].FindControl("CheckBox1");, when the it hits, open the "Autos" window (you can find this window under "Debug" menu "windows" sub menu item) and check the type of the row.Cells[3]. Check does it have control named "Checkbox1".

Then step into using the "F10" key, check the value of the CheckBox chk, look whether it is not null, and finally, if you do find that the check box exists, then look for whether has it "Checked" stte set to true.

Can you add bit more sense to your question?

I am not sure this is a mistake while typing this question or this is the actual code.

You do not need a variable to keep the index of selected row in listView. List view already has aselected items collection. Assuming that only one item is selected, getting that index will be:

if (listView1.SelectedItems.count > 0)
{
ListViewItem selectedItem = listView1.SelectedItems[0];
}

In the case like above, it should be using for loop instead of foreach.

for(int index = 0; index <listview1.Items.count; index++)
{
if (listview1.Items[index].SubItems[2].Text.Equals(name.Text))
{
//If text is found, select row at the current index
listview1.Items[index].Selected = true;
label1.Text = listview1.Items[index].SubItems[0].Text;
label2.Text = listview1.Items[index].SubItems[1].Text;
label3.Text = listview1.Items[index].SubItems[2].Text;
}
else
{
//If text is not found, deselect row at the current index
listview1.Items[index].Selected = false;
}
}

The description of your project sound moderate amount of coding involved, but you saying, the code above is a first code you have written. It sounds you need a lot of homework to do on programming before even you think about doing this project.

Description of your question and your code doesn't match. Where is the code that actually do something, apart from a console application that reads a name?

How does your solution assign values to the label as asked in the question?
What is the point of having that "searchIndex"?

Yes, because the salt is random, you need to save the salt that used for creating the hash at the first time, so when the next time user login, you use the same salt. Otherwise if you use new salt, the hash will not be same, although the user enters the correct password.

Hi Dave,
You are not checking for itemQu for null, Convert.ToIn32(null) will throw exception.

Also according to you code if the itemPn is null, then you not using the itemQu, this is why I have optimized the code in my solution version 4 such that, if the itemPn is null the code will not check for itemQu and you will not need to allocate an extra variable 'exitLoop'. Remember, every line of code is going to allocate some memory and consume time. Remember the less line of code the better the throughput.

Hi Maciej,
The "xlsSheet.Cells[iLoop,1]" is a dynamic type, it returns a type during runtime, so during compile time you will not know what type is going to return, according to Microsoft we should be using "dynamic" type as
dynamic itemPn = xlsSheet.Cells[iLoop,1];

string str = (itemPn != null)? itemPn.ToString(): ""; // there is no reason why you shouldn't parse the type as it is, if you know the retuen value is text or a number, rather than converting to string.

http://msdn.microsoft.com/en-us/library/vstudio/ff926074.aspx // half way down the page "Avoid the use of var in place of dynamic".
http://msdn.microsoft.com/en-us/library/vstudio/dd264741.aspx

What are you trying to achieve?
in your code,
you are getting the name of the type, and then the type and the collection of methods in that type, yet you haven't defined what is in the "AllTypes" collection.

You cannot call the method directly like frmB.PerformInterfaceMethod(); unless it is static.

from your comments it sounds like you have

1) Form B initialised,
2) Form A open
3) you are trying to access a method in from B from Form A.

in this case parse the Form B as parameter into form A.

public class FormA
{
From _frmB;

public FormA(Form frmB)
{
_frmB = frmB;
}
private void DoSomething()
{
_frmB.PerformInterfaceMethod();
}
}

See my edit.

As the keys are string, it might be spelled wrong or the columns has not given a key id.

Try a little test to check that all the columns has keys using this code below:

foreach(var column in ultraGrid.DisplayLayout.Bands[0].Columns)
{
Console.Out.WriteLine(column.Key);
}

What do you mean by still no luck? can you elaborate where it is going wrong?

If you tag this as C++, you might get effective answer. I wonder how many C#ers know c++ :).

Hi, how is your code any different from the original code written by the author of the question?

Why converting an object into Boolean, checking if it is "true" then converting to string?

What would happen if the values are false? Wouldn't the query become just series of commas?

What if the value is null, will the compiler convert a null to Boolean? Will that return "true"?
What would happen when with "null.ToString()"?

A duplicate question has been raised by the same member.
http://www.codeproject.com/Answers/559577/whenplusplusradioplusbuttonplusclickplusinplusdata#answer3

when sql can perfectly handle Boolean type, why change to string. In programming if the developer can code something in primitive type, then it should be left alone in primitive type. Converting a primitive type to another type and back again into primitive type is totally unnecessary.

You can get the lpram value from winProc() function. but why would you need to get lpram of key pressed in C#? The key pressed event is there if you want to call a function when key pressed. also there are key down, key up events if you need so.

Jegan

Gotcha!
gv_gsk.Rows[i].Cells[j].Value.ToString();

If the value is null, ToString() will throw exception, and nothing will work from that point.

remove the ".ToString()" and have ago.

Jegan

Text is specified to that range object,
Value is specified to that range,
Value2 is specified to that cell.

although the Text and Value can do the job, value2 is more brute force.

Thanks!

Have you used the "range.Value2" property as in my revised answer?

Well presented answer!

It is just a matter of rearranging the for loop, but I cannot test your code as I do not have your complete code.

There are couple of thing, move the using statement section out side the for loop, move the AddQRTag call back inside the for loop, as below.

using (var dc = new DataContext())
{
// Add record stub for Assessment unless one already exists
Assessment a;
a = dc.Assessments.FirstOrDefault(
c => c.DocumentID == d.ID && c.FeedbackUserID == u.ID &&);
if (a == null)
{
a = new Assessment()
{
DocumentID = d.ID,
FeedbackUserID = u.ID,
PageNumber = inputDocument.PageCount,
ID = Guid.NewGuid()
};
}
a.LastGeneratedDT = DateTime.UtcNow;
dc.SubmitChanges();
}

for (int idx = 0; idx < inputDocument.PageCount; idx++)
{
// Add copy of page to new document
PdfSharp.Pdf.PdfPage newpg = outputDocument.AddPage(inputDocument.Pages[idx]);

// Add tagging to the top or bottom of the page
PdfSharp.Drawing.XGraphics gfx = PdfSharp.Drawing.XGraphics.FromPdfPage(newpg);


string gurl = a.ID.ToString().Replace("-", "");
string gocr = "*" + gurl.Substring(0, 10) + " " + gurl.Substring(10, 11) + " " +
gurl.Substring(21) + "*";

// prep the visible string
AddQRTag(gfx, 3, 3, baseQR + gurl, gocr);
}

I am not sure what do you mean by "What am I doing here and Why?"

You may use global variable if the application has some default values that get populated in multiple of forms, if the use changes the default value, the new value will be stored in the data store but if the user decided to revert back to default value, the values from the hard coded global variable will be applied.

In OO the variable are never exposed as public they are always private to the class it is belong to, it is only exposed either as Properties or Geters and Setters.
Here is an article about what a class should do http://pragprog.com/articles/tell-dont-ask .

const int = this variable will receive a value only during its construction,
static const int = there will be only 1 such class-wide data member.

I hope this helps.

Yes! you can use the background worker to start the second process in separate thread and use the background worker progress event to update your progress bar to notify the user. When the background worker sends the work complete event, then the first process can continue with what it was suppose to do.

Hi, you open the file only once, then you iterate through the cells to add values into cells.
so you will have a for loop like this below:

Then you are using a dll that is build for x64. you need to check all your references target platform are correct.

Have you tried with changing the target to x86?

Have you made sure that all the projects involved are set to the same target and have you clean the binaries before rebuild?

I do not know much of JQuery my friend. Sorry.

You cannot change the margin of the fonts, But you can change the Font family to fit in your text box, such as Lucida Console font family with 8px will adjust the height of the text box to 15px, and just about readable.

You are again missing the point, Font size and the Text box height are related, if you set the font size to 15px then your textbox height will increase to 30px. you cannot increase one and decrease another, they both will increase or decrease relatively.

Yes I understand that.

Hi,
"Parallel.Foreach" loop will execute all of your urls at once, if you want to access only 100 urls at a time, but all of those 100 in parallel; then you need to put them inside a for loop with increment of 100.

private void DownloadAsynchronous(List<string> urls)
{
for (int i = 0; i < urls.Count; i += 100)
{
string[] urlStrings = new string[] { };
urls.CopyTo(i, urlStrings, 0, 100); // this needs more attention as the array count may be less than the copy count and throw index out of bound exception.
Task.Factory.StartNew(() =>
{
Parallel.ForEach<string>(urlStrings, url =>
{
Download(url);
});
}).Wait();
}
}

You need to give attention to the urls.CopyTo line as this will throw exception.

Jegan

Can't you change the design, instead of grabbing the data from the list view. you separate the view from model, so that you have the collection of list view items "ListViewItemCollection", you do whatever you want with them in the parallel task and when the background worker replies you with progress, you update the listView with whatever available in the "ListViewItemCollection".

Jegan

Hi,
I tested it with 1000 item, and i did not see the list view freezing, list view seems responsive.

you must remember the background worker is different thread to the main thread which created the listview. If you try to add items into list view in background worker, you will have cross thread exception.

you can switch off the cross thread check, but I wouldn't recommend.

My concern is that, that the Sharepoint is set to German culture, this may over write any of your settings at the point when the data is read from Sharepoint. This is a tricky scenario!

It is not specific to my implementation, it is to show that there should be a end of data mark. The user can leave it as it is or change it to something that they want once they know how to.

If I make the code generic, yes, the experienced developers will understand, BUT the beginners will get confused. This code is for a beginner who have never worked on serial comm before to get the gist of how to open a serial port and send/receive data.

Regards
Jegan

The code I wrote certainly works in WinformApplication, I am not sure about asp.net.

The additional code you wrote
if (!ch.Checked)
{
count--;
}
is wrong, if the first check box is not checked, you will decrement your count (means negative count), further down the multiplication by the negative count will be negative, so the progress bar will not display. In my original code, it will only increment the count if the check box is checked per check box.

Can you post the xml file?

Can you also post the code behind the "WorkflowModulCapturaPrelucrareCaptura" and the "WorkflowModulSplitAnalizaSplit" ?

Your mc_s data is written to file "C:\Users\SmartAdm\Documents\visual studio 2012\Projects\Workflow_Robo\Workflow_Robo\workflow.xml"

and your mc data is written to "C:\Users\SmartAdm\Desktop\Workflow_Robo\Workflow_Robo\workflow.xml"

These are two different location, so your xml file will show only one data set.

Also can you post the xml data with elements rather than just 1's?

I didn't quite understand why do you want to split the date in sql query when you already have a deserialized object. you just have to get that object and pick the date format you want such as

DateTime dt = testIn.PartInfo[0].InstallDate;
string shortTime = dt.ToShortTimeString();

If you are not using the deserializer, then sql.SELECT will give you that date value as string, so you can split on string as

string installedDate = "2013-02-04T17:16:56.383+05:30";
string[] parts = installedDate.Split(new char[] { 'T' });
string date = parts[0];
string time = parts[1]; // remember this includes the +05:30 at the end, you have to take care of this.

In this case,
When you read the data from database, why don't you read it as InvariantCulture.

Which part actually get written to the xml file and which part doesn't? you seems to have two objects writing to two different files. Is both files writing the first node only i.e. mc_s.M0_RevertSnapshot on the first file and mc.M3_CopyResultonserver on the second file?

Your question on the title and the question in the content are two different thing. which one do you need answered?

What do you mean by change user setting directly? did you mean in your PC?

Are you not binding the data source to the grid view?

You can do it that way but it is not elegant. Perhaps you should think of using a separate form for the list box and show/hide them as needed.

Hi,
Uk = Europe
12,345.67 = 12.345,67

regardless of how the number are displayed the database will always store in InvarientCulture that is 12,345.67, BUT when its read, the reader converts to the current culture. As you said that the SharePoint is in German Culture, when its read the database, it will immediately convert to German culture.

The solution would be to force the SharePoint use the InvarientCulture.

Have you thought of docking the list box to "Fill"?

Hi,
On the first section of the code your serialising

WorkflowModulSplitAnalizaSplit mc_s = new WorkflowModulSplitAnalizaSplit();

as a type of

XmlSerializer xs_s = new XmlSerializer(typeof(WorkflowModulCapturaPrelucrareCaptura));

I am not sure the serializer will translate this correctly.

Also you could optimize the if statement as follows:

mc.M3_CopyResultonserver = Convert.ToByte( triStateTreeView1.GetChecked(triStateTreeView1.Nodes[0].Nodes[1].Nodes[1].Nodes[12]));

Hi These codes are for just opening the serial port and setting its properties. There is no code that contains your command protocol. All serial interfaces has some form of command protocol.

In serial communication like this, all operations are done through commands, and you must have a sets of command protocol to operate the turnstile that you are working on.

The code above will open the com port and send and receive messages. When the message is received, it will notify you via received event. It is up to you to process the received message according to the command protocol.

I hope this helps.

Lot of unnecessary code!

Dont write code unless you absolutely need to.

This is very unattractive!

Hi I've a lot of automation work, what is your actual problem? can you post your code?

Have you tried something like:

((DropDownList)GridView1.Rows[e.RowIndex].FindControl("DDLpursuit")).DataSource = dt_pursuit.DefaultView;

Or use xml serialiser, create an object that contains the xml attributes and parse it.

You expect someone to write the code for you? there are plenty of example on google how to read xml file.

Can you elaborate your question, serial communications are between two interfaces, writing a file to a disk is using a file or stream writer. Are you trying to read data from an interface and write to the disk?
