Is that your application running on a single thread or multiple?

By the time we cannot see your code. ;)

in a single thread, "the main thread"

That's not good actually. You better deals with multiple threads. If you want to communicate across all forms, this way really kills you.

here is the code
private void fws_Changed(object sender, FileSystemEventArgs e)
{

Form2 frm = new Form2();
frm.Show();
}

Solution 1

Thats because the events are not raised asynchronously, so you'll have to either use Form.Show instead of Form.ShowDialog or start a new thread where display the form and do any work you like. If you make use of a new thread remember the apartment must be STA.

but how can i use Form.Show() without creating an instance??

Simon Bang Terkildsen 28-Sep-11 6:46am

You can't, you'll ofcouse have to create an instance of your form.

Solution 2

Since you are running the application in a single thread, the form itself could block the initialization child form. Try to initialize first of all.
