Hi,
I make public some controls on the form and I new a class in a windows form and send this (current instance of the form) to that class as parameter of constrauctor.
Now when I want to set the Text property of a lable of form in the class this error appears:
"Cross-thread operation not valid: Control 'lblStatus' accessed from a thread other than the thread it was created on."
How can I do this?
Best wishes

if(InvokeRequired)
{
Invoke(blah)
return;
}
lblStatus.text = "I like Crazy frog";
betonglasermur.FeedDwarf(pur_is, 17);
ProcessStartupInfo.AintNotCreateNoWindow = (false && !true) != (true || false) ? false == true ? true : false : (true != false && false);

This is always a bad idea.

How very ugly

Use delegates to call a form and tell it to change it's UI elements. You can then either set things up to invoke the UI changes, when in another thread, or if you prefer nasty solutions, you can just turn off the cross thread operations error.
If you read the article I link to in my sig, and pay particular attention to the section on how to google error messages.

I wondered about this.
I've always avaoided doing this, and used delegates, as is is seen as bad programming practice by some.
However if I know(due to the design on the application) that a cross thread call will not cause a conflict is it okay to turn off the error?
You always pass failure on the way to success.

I'd say that's entirely up to the conscience of the individual. If you're OK with it, then why not ? I've done it, when I ported a C# 1.1 app to 2.0 and found that a progress bar that showed loading progress from another thread was not working and I just needed a quick fix. The code had run fine for a long, long time, and it was the first time I'd seen the error.

//Declare Delegate :
private delegate void RefToFunction(string s);
//create an instanse :
RefToFunction handle = new RefToFunction(Function_A);
//Define the function :
private static void Function_A(string s)
{
lblStatus.Text = s;
}
//Invoke The Delegate (From where u need):
string status = "Hello World";
object [] param = { status };
this.Invoke(handle, param );
and thats it all 
Have Fun

Hi,
is there anyway I can get a listview to scroll when either the mouse is scrolled or the scroll bar is dragged?
I have created a custom listview control by overriding WndProc()

You can handle the mouse wheel scroll event and scroll your listview

As far as I can see, you need to handle the mouse wheel event, then set the scroll position in code, or did I misunderstand the question ?

hello,
i'm trying to make the display of the group-box 3D and bold from the form
how do I do that?
|
|
|
|
|
Hello,
If I understand correctly, you wish to change the look of the GroupBox to 3D and
the Text portion to Bold using code.
3D style option is not available for GroupBox.
To make the GroupBox text bold, you can use the following code.
Font gfont = new Font(this.groupBox1.Font,FontStyle.Bold);<br />
this.groupBox1.Font= gfont;
I hope this will help.
Regards,
Allen

Is it true that using timers in Windows Services is not a good idea and the timers are unreliable for practical purposes since they stop firing the service after some time??
