I'm developing a 'socket programming solution for client server architecture'. There a client connects to a server and send messages.

But i got this error,"cross thread operation not valid" and found a solution as follows.

It has to pass the thread address but i dont know how to obtain a thread address.

Could you please tell me how to obtain a thread address.
This is the solution i found.

----------------------------------------

Thread mythread = new Thread(addressOf thread1);
mythread.start();

Sub MyThread1
' Working code
' Working code
' Working code
' Working code
' Working code
' Working code

AccessControl();

End Sub
--------------------------------

Thank you.

It not the address of the thread, it is a delegate for the method to invoke when the thread begins execution. Check the documentation on MSDN. Here is a sample.

Public Class Test
<mtathread> _
Shared Sub Main()
Dim newThread As New Thread(AddressOf Work.DoWork)
newThread.Start()
End Sub
End Class

Public Class Work

Private Sub New()
End Sub

Shared Sub DoWork()
End Sub

End Class

Hi Actually you don't have to obtain the address of a thread instead you provide the name of a function (Your thread function) and .net will find the address for you . AddressOf is a VB.net keyword that returns the address of a callback function.In C# you don't have to use any keywords .
For example:

<br />
Thread myThread=new Thread(new ThreadStart(MyFunction));<br />
myThread.Start();<br />

That MyFunction is a call back function that will be called when the thread is started and the ThreadStart is a delegate to MyFunction.

I need to save the entire form in bmp format. I 've used the following code:

Bitmap bi = new Bitmap(this.Width, this.Height);
this.DrawToBitmap(bi,new Rectangle(0,0,this.Width,this.Height));
bi.Save (@"c:\Test.bmp", ImageFormat.Bmp);

Problem: only the visible area of the form is saving in bmp format. the other part like area of the form occupied by scroll bar is not saving.

could you please give me any suggestions.

The regular expression to match single line comments would be

//.*$<br />

(with the multi-line option turned on) basically looks for // followed by any number of characters until the new line.

Sounds like you want to store a cookie on the local machine. You can't identify someone to store something local, because their IP address is likely to change the next time they connect.

using directives for a new file / class

In Visual C# 2005 IDE, can I customize the "using" directives that are automatically added when a new file or new class is added to the project?

Also in Express?

Heh, I didn't know that before you asked, I was going to google how to manualy add/modify item templates, and look, there is IDE option to do that. And right in File menu. Cool | :cool:

Row select on DataGridView

Hey guys

I have a datagridview populated with entries from a database. I have set the selection mode of the grid to fullrowselect so that a click on any cell will cause selection of that row. In this selection event I open a new form showing the data contained in that row. This works fine, however when you click on a column header it still tries to select that row. Is there any way of stopping this?

Thanks in advance

What event are you using?

I used the doubleClick event somewhere in an old app, and it just refers to the SelectedItem in the datagrid. Then if you doubleclick the header, it just opens the record that was selected last.

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

I was using the selectionChanged event of the datagrid, is there anyway of knowing which row the selection was made on? ie if row is header row type then do nothing?

you could use an event like CellClick or RowEnter, they have DataGridViewCellEventArgs where you can access the ColumnIndex and the RowIndex of the selection.

private void dataGridView1_RowEnter(object sender, DataGridViewCellEventArgs e)
{
    // e.RowIndex
    // e.ColumnIndex
}

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}
