Hello
Mav is right. Yet!! As my habit of making crazy suggestion;P, you can make a timer that checks the destination file's size each -let's say- 50 milliseconds, and updates the ProgressBar according to the percent of the current size/Total size.

its not an issue about refreshing, I dont know how to even make it invoke a way to update the pb after so many bytes written. I only know how to copy in general with File.Copy or FileInfo.CopyTo but neither of these provide a way to update a pb after a specified about of bytes and thats what i need to do.

Hey guys, since i'm trying to do this from a c# windows app i'm posting here, even though this could go in a couple areas. What i'm trying to do is post to a website that will create a file...dont care about getting the file back, just need to send the WebRequest to the site, but i'm getting a System.Net.WebException error 401. I've checked IIS on the server and the site i'm trying to use is set up exactly like another site which i can post to just fine. (yes i realize that this seems like an IIS/permissions problem, but i've checked the settings 3+ times they identical) if it is an iis problem, a pointer to it would be greatly apprecieated. here's the code i'm using to make the request.
url is a string that i get from the app.config file right now it = "Http://<local server="" name="">:<port number="" of="" the="" site="">" i've also tried the server's ip. i specifiy a port number because this server also runs our mail program which has its own site that takes over port 80...we have several site running on machine all w/ different port numbers and they work fine..the port for this site is 877, its duplicate site(they each point to different databases, dev and testing) is 888.
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method="GET";
request.PreAuthenticate=false;
request.GetResponse();
i've also tried POST instead of GET and i've tried a System.Uri object to create the WebRequest, and i've tried with and with PreAuthenticate. Oh, this is an internal use only app, so i'll always have access to this server, just thought i'd mention that before someone asks why i'm doing this.
Thanks guys,
John

Hi guyz,
I'm using C# for my program and Crytal report for printing of sales report but I got this error after packaging and testing of my program:
"Cannot find KeycodeV2.dll, or invalid keycode."
I'm using VS.net 2003 and I don't know if i'm missing something during the packaging or it is because of my VS version.
Please help...
Best regards,
Paul

I created a DataViewManager on a dataset here is the code:
obj = new CSIA.Controller.MembersFullView();
obj.Read();
DataViewManager dataManager = new DataViewManager(obj);
dataGridView1.DataSource = dataManager;
dataGridView1.DataMember = "Members";
dataManager.DataViewSettings[0].RowFilter = "[Member Number] = '1105'";
.....Members is the first table in the dataset
What I don't understand is that if I apply the RowFilter before setting the
DataSource I get a filtered view but if I put it after I get the full table.
I thaught filtering the DataManager would update the DataGrid as a DataView
would. Am I missing something ?

Hello
I don't know, but!! I guess your question is already self answering.
You've changed the filter of the DataTable indexed zero. You have to populate the view with that new filter.
That's is dont by either assigning to the DataSource property because it populates the records of the table through the already filtered view, or by using DataViewManager.CreateDataView() method
If someone knows otherwise, please post!
Regards

I have a thread (which is not the main GUI thread )that I want to be able to create a form using the Show method.
The thread basically loops for commands and responds to them. Some of the commands are to display a form - and then wait for the next command.
Now when I try to do this the Form freezes i.e. not responding. Now I assume that is because the thread is blocking waiting (Monitor.Wait) for the next command. I suppose this blocking prevent the GUI from responding to events.
So my question is related to this problem.
1. Is is good practice to create Form from a thread other than the main GUI
2. Can I do a for.Show method and spawn it into a worker thread?
All thoughts and suggestions would be appreciated.

Hello

If you want your working thread to be blocked by the shown forms, you can use it to show these forms. Simple, isn't it??
OTOH I don't think is what you want. So, simply make a thread for each form that is shown. The thread should be alive as long as the form is visible. Once the form is closed, abort the thread nd dispose it.
And yes of course!! Sometimes this is a good practice, depending on the structure of your program.
LiamD wrote: Can I do a for.Show method and spawn it into a worker thread?
I don't know what is a "for.Show" method, but you can -and probably should- show each form on its own thread as above.

I was concerned because i have never seen any examples of projects creating a thread for each form.
Can you please give an example of code for this? Something liek this ...
Form f = new Form();
t = new Thread(new ThreadStart(f));
t.Start();
I just want to make sure that I will not run into problem using this method when running in a multi threaded project.
By the way I meant to write Form.Show() method above.
Thanks,
Liam

Hello
Well, running into trouble in multithreading is as easy as slipping in the mud in a rainy day!! There are two scenarios. One if you want to keep track of each thread -for several reasons I suppose-. This is the hard way, so I'd rather skip it for now .
The easy way is to launch each thread and let it die as it finishes without tracking -Thank God for the GarbageCollector!!-. Here is a sample code:
private void button2_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e)
{
Thread MyThread = new Thread(new ThreadStart(MyThreadMethod));
MyThread.Start();
}
private void MyThreadMethod()
{
Form1 MyForm = new Form1();
MyForm.ShowDialog();
}
The Thread will die and get collected once the form is closed. Carful not to open too many forms though.
Regards

Hi,
Try using an array. Like this:
<br />
string []items = new string[13];<br />
And then create the function:
<br />
public string Save(int index,string Value)<br />
{<br />
items[index] = Value;<br />
}<br />
Do your best to be the best

That won't work, Tareq. And it's bad design too, don't do that. Instead, use a string[]:
string[] items = new string[13];
...
save(int ID, string Value)
{
items[ID] = Value;
}

Hello
Put your items in an array and access them using the index.
string MyItems[] = new string[13];
public void Save(int ID, string Value)
{
MyItems[ID] = Value;
}

Hello,
if you whant to make it dynamic some day, you should use "System.Collection.Specialized.StringCollection"
All the best,

Even better than an array of strings!
private dictionary<int, string> items = new dictionary<int, string>();
public void save (int id, string value)
{
items[id] = value;
}

Maybe I should clarify why its better... your "id"s need only be unique with a dictionary, whereas with the string array they would need to be, unique and sequential. Also stuck in a certain range (unless you used an offset).

I have inserted a datagridviewcheckboxcolumn. But the values of those the checkbox cells are all set to null by default. How do I change them all to "false" which is unchecked?
|
|

Hello
Is your DataGridView databound?? In this case you could just use this line of code to return false to the datasource when the user leaves the value null:
dataGridView1.Columns[0].DefaultCellStyle.DataSourceNullValue = false;
If you still want to initialize the values of the cells, I remember something about default values in DatagridView, but i don't seem to recall it at the moment..
What I can think of now is to handle the RowsAdded and initialize the new cells value to false.
Regards

Hi
I have set the datagridview.datasource to the defaultview of a datatable. Is it databound then? The thing is that the checkbox column is inserted to the datagridview with null values by default.
The idea is to let the user to check for export. Cos the unchecked boxes are of null values, I've got an error when the null value is accessed.
|
|

|

Hello
I provided you with two possible solutions in my last post. Are they not suitable??
1- You could ignore the null value and return false to the datasource. This should eleminate the error:
dataGridView1.Columns[0].DefaultCellStyle.DataSourceNullValue = false;
2-Otherwise you could handle the RowsAdded event and set the value of your column for each new row to false
Regards

Hi
I've tried both but they don't seem to work. It could be that the datagridview is not databound??? For the 2nd solution, it seemed to work initially, but I don't know why the value switched back to null again. I have made the datagridview a global variable, so nothing should have changed the value back.
Now I don't know what to do.

Hello

What??!!
What do you mean switched back again?!! Are you sure you did initialize them to false??
Also, how do you populate your DataGridView if it's not databound?
Regards
|

Hi
Yes, I did initialise them to false in the "try" block and they switched back to null in the "finally" block.
I'm not sure if the DataGridView is databound or not. As mentioned in my earlier messsage, I have set dataGridView1.DataSource to a defaultView of a datatable. Is this databound??
