How can I debug a form calling an openFileDialog?

[franknagy]

Gentle Advisors,
I have a form where a button selects an image and passes it on a control of this form and an other one.
I wanted to debug the statements but I got an error message at the source line

if (openFileDialog1.ShowDialog() == DialogResult.OK)

:

"Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttrib ute marked on it. This exception is only raised if a debugger is attached to the process."

What have I to do? What have I to insert in Main?

Regards
Frank

Hi,

Add the STAThreadAttrib ute attribute on the Main method.

C#

[STAThread]
static void Main(string[] args)

{

}

Thanks,

Thanks,

After insertion of the magic

[STAThread]

line the debugger survived the OpenFileDialog call.

Please explain me what are the other effects of this magic word.
Where can I find a documentation of magic words to be inserted in square brackets of C# source files?

Regards
Frank
