When i use the code:
frmRegister.Show()
I get this error when it attempts to show the form:
An error occurred creating the form. See Exception.InnerException for details. The error is: Illegal characters in path.
How can i get rid of this error? I only want to show a form...
Regards.

Path? I'm just showing the form.
Below is the 'Exception in detail':

You appear to be creating a StreamReader somewhere when you create/display the form. And by the sound of the exception, you're passing an invalid path to its constructor.
I removed line 3 and it seems to work. I was declaring a StreamReader there.

Good to hear you got it working.
