Prevent Form from loading [Resolved]

[teamdad]

I have a proplexing problem.....

[code]

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim Check As Integer, filepath As String
filepath = "C:\Help.txt"
Check = Len(Dir$(filepath))
If Check = 0 Then
Dim Frm As New Form2()
Frm.ShowDialog()
End If

End Sub

This code does it's job of throwing the From2 up if the file don't exist but on Form2 using a button is it possible to stop Form1 from loading?

I can get the Form2 to close with Me.Close() but it still loads Form1 after Form2 closes.

You can do two things here:


1. Do your file check from a module and set that as the startup form, that way no form will be visible until after the check has ben done.

2.Use Me.ActiveForm.Hide in the "Form1.Load" event, and then show it or keep it hiden after the file check.

It doesn't like Me.ActiveForm.Hide() for some reason. Durring debug it gives.

An unhandled exception of type 'System.NullReferenceException' occurred in WindowsApplication15.exe

Additional information: Object reference not set to an instance of an object.

If I use Me.Hide() it don't give errors but it don't hide it either.

Sorry,

The first one you can't put in the load event, put it in the paint event.

Or Try the second one:


In a module:

Public Sub Main()
'Do you file check here
'Then show whatever form you'd like
End Sub

Also make sure to set the startup object to "Sub Main()"

This works for sure


Let me know if you have any probs.

Thanks Hole-In-One,

I was trying to avoid using a module for some reason but I guess they can be a good friend every now and then

When I tried the paint method to use the Me.ActiveForm.Hide() it gave the form about a second's worth of flash so I opted to go with the module.

You guys rule
