Unload form in Form_Load()
Hi,
I have two forms:
- frmMain
- frmPreview
I call frmPreview from frmMain using
Code:
' This button is on frmMain
Private Sub Command1_Click()
'
' some code
'
frmPreview.Show vbModal
'
if globalVar = True then
' some other code
endif
'
End Sub
In the Form_Load() of frmPreview I'd like to be able to stop loading the form, unload it and go back to frmMain and execute the more code.
Can I unload a form from its Form_Load()?
Something like this... that actually works
Code:
' This is my frmPreview
Private Sub Form_Load()
If something then
globalVar = True
Unload me
endif
End Sub

Re: Unload form in Form_Load()
You will get an trappable error indicating the form is already unloaded and it will highlight the .Show statement on the calling form. You can get around that though, by trapping it
Code:
'on form1
Private Sub Command1_Click()
On Error GoTo ErrTrap
Form2.Show
Label1.Caption = "Hey there"
Exit Sub
ErrTrap:
If Err.Number = 364 Then 'object was already unloaded
Resume Next
Else
MsgBox Err.Number & " " & Err.Description
End If
End Sub
'on Form2
Private Sub Form_Load()
If blnStopLoad = True Then
blnStopLoad = False
Unload Me
End If
End Sub
blnStopLoad is a global boolean I created for toggling whether or not to load the form.

Re: Unload form in Form_Load()
probably better to test the value of something before loading the form, or just set it to visible =false
i do my best to test code works before i post it, but sometimes am unable to do so for some reason, and usually say so if this is the case.
Note code snippets posted are just that and do not include error handling that is required in real world applications, but avoid On Error Resume Next
dim all variables as required as often i have done so elsewhere in my code but only posted the relevant part
come back and mark your original post as resolved if your problem is fixed
