If you do not access to app.xaml it doesn't matter, whoever calls your MonitorProfileOutputViewModel needs to initialize and set the view model before calling them. The app.xaml is an example where the MainWindowViewModel has been called. if you MonitorProfileOutputViewModel has been called in another file, then initialize and set it there.

Sorry, I missed one more thing;
second for loop should have
oRange.Value2 = itemDataGridView.Rows[i].Cells[j].Value;
Jegan Thiyagesan 14-May-13 7:49am View
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;
Jegan Thiyagesan 14-May-13 7:40am View
ok, then give the full namespace Excel_12.Range.

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.
Jegan Thiyagesan 16-Apr-13 11:59am View
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.
Jegan Thiyagesan 16-Apr-13 10:46am View
What you need is a permutation algorithm and assign the value for each set.

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.
Jegan Thiyagesan 21-Mar-13 5:28am View
Are you sure?
Jegan Thiyagesan 21-Mar-13 5:28am View
Why not? The author did not specifically say that there should be only one + symbol and the location that the symbol.
Jegan Thiyagesan 20-Mar-13 11:07am View
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.
Jegan Thiyagesan 20-Mar-13 8:06am View
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.
Jegan Thiyagesan 19-Mar-13 16:16pm View
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.
Jegan Thiyagesan 19-Mar-13 15:46pm View
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".

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.

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;
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;

void button_Click(object sender, RoutedEventArgs e)
lbl.Visible = false;
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.

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.

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.

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;
//If text is not found, deselect row at the current index
listview1.Items[index].Selected = false;

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. // half way down the page "Avoid the use of var in place of dynamic".

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;

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()"?

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.

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;

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 .

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.

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".

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.

"int" is a primitive type and it will always have a value, you cannot assign null to a primitive type.

if you want you can make your "objdal" to a nullable "Integer" type or a "string" type.

Have you tried this in your program:
Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture;

See link in stackoverflow:

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!
Jegan Thiyagesan 25-Feb-13 4:39am View
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.

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

The additional code you wrote
if (!ch.Checked)
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.
Jegan Thiyagesan 21-Feb-13 10:47am View
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?

Are you not binding the data source to the grid view?
Jegan Thiyagesan 21-Feb-13 9:12am 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.
Jegan Thiyagesan 21-Feb-13 8:22am View
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"?
Jegan Thiyagesan 21-Feb-13 6:57am View
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]));

Where did you add break points?
Are you using any third party dlls?
Jegan Thiyagesan 20-Feb-13 9:52am View
Can you put a break point in "InitialiseComponent()" and run the app, If it does stops at that break point, press the F11 key to step into that method and continue F11 until the exception throws, note down the line that the exception throwed. If the Break point doesn't get hit, then let us know.

Hi the stack trace is telling you that some unsafe native method is being called.

A very good answer. In fact there should be a filter mechanism in CP website that throws these people out straight away.

Jegan Thiyagesan 18-Feb-13 11:37am View
This is SQL time format, when you serialise this to DateTime object, .Net will automatically recognize that. then you can use that serialised DateTime object to get the correct sreing format you want.

Well done!
Carrier Detection is normally done between micro controllers, not on PC, so I assumed you will be using a command, rather than receive line signal.

Hi there is a "broadcast" function in the TCP server, which will sends the message to all connected clients.

Jegan Thiyagesan 18-Feb-13 4:37am View
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. You need to get hold of the command protocol that applies to your turnstile or use an available hyperTerminal ( to reverse engineer the command protocol from you turnstile.

Jegan Thiyagesan 18-Feb-13 3:55am View
Hi I didn't quite understand your questions.
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.

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?
