HELPPPPP!!!!!Run-time error '5 Invalid Procedure Call Or Argument

[ravioli]

I was using this software(VB6.0,CR8) for the last couple of
months with no problem. It all started all of a sudden when the application is trying to pass the control to the next form as I am getting an error "Run-time error '5 Invalid Procedure Call Or Argument ", which really baffles me as I have not made any code changes and it was working perfectly well. This is the code that is being highlighted when I say Debug.

B.Text2.SetFocus
-->Where B is the name of the form, I have written this piece of code in Form A.

Any help will be greatly appreciated.

Have you loaded form B before you're setting focus? It seems that you could place the setfocus in the onload portion of form B.

I always use On Error Resume Next for a SetFocus.

on error resume next
    B.Text2.SetFocus 
on error goto 0

You can't do a .SetFocus during Form Load.

If you reference a control on another form and the form isn't loaded, it will be loaded. So perhaps Form B is normally loaded already, but in this case it isn't so it gets loaded by being referenced; and then the error.

You can do a .SetFocus a little later in Form Activate.

Usually there's other ways to do what you want. From what I've read, this type of code will not work in VB.Net.

I have already loaded the form B as follows
a.hide
b.show
b.text2.setfocus

It used to work perfectly well, but all of a suddent it stopped working the way it used to. Any idea??

Your help is greatly appreciated

1. b.show
2. b.text2.setfocus

The problem is that #1 hasn't finished before #2 gets executed.

You could do:

B.Show
Doevents
Doevents
B.Text2.setfocus

But it would be better to find another method. Is text2 not normally the first control to get focus on Form B?

 

[ravioli]

no it all depends on the action on form A, based on some
conditional checking on form A I will set the focus to Text1 or text2. Its how my forms are working, if the user selects adding items in form A then I will set the focus to Text1, if the user selects to retrieve an item from database in Form A then I want to load/populate the Form B and setfocus on Text2.

 

[balves]

Put a public property or a public variable on Form A.

In Form B's Activate Event

If FormA.property = 1 then
text1.setfocus
elseif FormA.property = 2 then
text2.setfocus
else...
