VB Forum / General 2 / December 2004Weird VB error
Hello, I'm experiencing a strange problem in vb 6.0. I set up a form with two command buttons in a control array and the form_load code is as follows: Private Sub Form_Load() Command1(1).SetFocus End Sub What's odd is that when I run this, I get the error: Run-time error '5' Invalid procedure call or argument Now, I know I've done this before and did not get this error. Is there some reason why VB decided to barf on this? I can't think of anything. Thanks, * Robinson > Hello, > [quoted text clipped - 13 lines] > there some reason why VB decided to barf on this?

If the form is not visible, neither it nor it's controls can have the focus. Try Me.Visible=True before the .SetFocus. Because you did this in the Form_Load event, Command1(1) may not be loaded yet. Put DoEvents before .SetFocus. Command1(1) is may not be visible or not enabled. Check those. Austin  SignatureYou programmed with 1s and 0s? We only had 0s!

There are two ways to handle it. Either move your SetFocus statement to the Form_Activate event, or call Me.Show in Form_Load to force the completion of the form, then call SetFocus.

Maybe, just maybe, the program starts under different circumstances (Start menu vs double click an associated file, for example) that requires different initial focus.

Huh? An application does not know how it was started. Jan Hyde (VB MVP) SignatureProtuberance: Small insects that are fond of potatoes.

Your control is not visible and able to take focus until its container is loaded ie Form. Bit of a pain because of the side effects, leave that to you though. Damn this new Google interface, Dave |
