the form that wont die...

This is a VB6 question.

I seem to have a problem with a form that should be unloading or at the very least become not visible. For whatever reason when another form is shown (form2.Show as an example) or made visible (Form2.Visible = True, next line would say Unload Form1 for instance), that same form (Form1) will come back up, including any message boxes as well... I quit them 2ce (sometimes 3 times) and they will finally go away for good.

It seems that on the first form in the code, even after the next form called is loaded, the code is re-read again even though i have definately unloaded it (it = the first form (Form1)).

Any ideas why this may be happening? This really is odd.

I will supply more code if needed.

thanks for any help.

A copy of the actual code would be nice... I'm learning myself and this is definitely issue that I foresee in my future.

ok BigSeckC,

Here is the code I am having an issue with at the moment.

Visual Basic 4 / 5 / 6 Syntax (Toggle Plain Text) 
  1. If Len(pass) <> 0 And InStr(1, pass, "reset") = False Then
  2.         frmVerify.Height = 2100
  3.         Label2.Visible = True
  4.         Command1.Enabled = False
  5.         Command1.Caption = "Loading..."
  6.         Pause 1.5
  7.         Unload frmVerify
  8.         frmenter.Visible = True
  9.  
  10.     ElseIf InStr(1, pass, "reset") Then
  11.             Unload frmVerify
  12.             Form2.Show
  13.             MsgBox "Your Password has been reset.  Please make a new one now."  
  14.  
  15.     Else
  16.         frmVerify.Height = 1910
  17.         Command1.Visible = True
  18.         frmenter.Visible = False
  19.      End If
  20. 1:
  21. End Sub

Now as you can see a number of things can happen here. But if it calls for a password reset, then the message box comes up 2 more times after it is clicked out. If the frmenter form is called for, then after the correct password is entered, the password form does go away, but comes back over and over endlessly. The code for the frmenter click is below:

Visual Basic 4 / 5 / 6 Syntax (Toggle Plain Text) 
  1. Private Sub Command1_Click()
  2. Dim pass As String
  3.    On Error GoTo program
  4.  
  5. Open "C:\test.tst" For Input As #1
  6. Input #1, pass
  7. Close #1
  8. If Text1.Text = pass Then
  9.     frmenter.Visible = False
  10.     Form3.Show
  11.  
  12.     Else
  13.     enter = MsgBox("Incorrect Password", vbError, "Error")
  14. End If
  15. Exit Sub
  16. program:
  17. Open "c:\test.tst" For Output As #1
  18. Write #1, "reset"
  19. Close #1
  20. End Sub

I cant figure out why this is happening. The only thing i have found that will stop frmenter from coming back is to add 'vbModal' to the form3 that is called from form2 in the code directly above. I do not like using that however, as it isnt really solving the problem.

Any help would definately be appreciated.

Ok... time to state the obvious... it's Looping the code.

Would a 'Do...While' help in this situation? I'm asking this as a general question to anyone...

Seems like that 'could/would' work - but I'm not proficient enough to say 'do this'.

Have you tried googling a 'pw reset snippet'? I had to do that once and it did help me understand what I was doing wrong
I am who I am...I do what I do

no i havent looked for that.. I will do it now. I know its looping the code, but i dont know why, obviously... hehe. thanks for the help.. ill check it out.

also, Im not sure how a Do While statement would help as that is a type of looping in itself. If Then isnt supposed to loop at all. That is what is so odd to me about this. It goes back to this code no matter what I do. Im sure that solution is fairly simple, yet it it isnt obvious to me, yet.

Thanks again.

I know - it's truly weird - the reasoning behind the Do..While is:

"technically" if the code is "looping" without being told to, a Do...While 'should', in effect, negate the situation. (e.g., Do this - While that - Then Quit)

The only other things I can think of would be:

1. Run the program on another box - "maybe"there is 'something' on the code box that is causing the anomaly. (e.g., bad memory address, bad spot on HDD, etc.)

2. Re-write the code using a New Form and Test with each New Line - maybe even on a different box - 1 of 2 reasons...

A. The existing file could be corrupted. <-- not entirely impossible.

B. In testing each line, you would be narrowing down where 'the loop' is coming into play.

...right now, it's honestly the only things I can think of.

*crosses fingers for a corrupted file...

Not to insult your intelligence, but by box - I mean computer. Just in case someone else was wondering...

...why do I have this sneaky feeling I'm gonna run into this too?...

Just looking at the code again...

What procedure is tied to '1:'?

vb Syntax (Toggle Plain Text) 
  1.      End If
  2. 1:
  3. End Sub

...maybe there is something there...

I'm assuming that the program is being told to wait 1.5 seconds before continuing. Is 'pause' not a valid command?

It makes sense 'logically'...but if it's not a command - it's not a command.
