Thread and ShowDialog

[Guest]

I have a problem about threading when using ShowDialog method.

I have 2 forms and first one opens second one as modal. Form2 (second form)
has a progress bar. Any suggesstion.

Thanks.

HEre is my code...

private void Form1_Load(object sender, System.EventArgs e)
{
Thread t = new Thread(new ThreadStart(test));
t.Start();
this.label1.Text = "12 3214 ";
}

private void test()
{
Form2 d = new Form2();
d.TopMost = true;
d.ShowDialog();
}

// Form2 code....

private void Form2_Load(object sender, System.EventArgs e)
{
for(int i = 0 ; i < 100 ; i++)
{
this.progressBar1.Value = i;
Thread.Sleep(50);
}
}


Thanks

Always show your forms in your app's main thread...

Thanks sir but is there any way to open the progress window as modal. (with
ShowDialog method)

Considering how ubiquitous the need for progress dialogs is -- and how
complex it is to program them -- why hasn't any of the component vendors
added it to their suites? I would *totally* pay money for one!

You can write a progress dialog in about 3 minutes. Check out ProgressBar:
