Transitions (eg wipes, fades)

I'm using VB5 on WinNT and Win98.

How do i do transitions such as screen wipes or fade ins and fade outs?

I have managed to make a screen wipe by putting a frame on top of everything else and then expanding the width of the frame to hide everything underneath but this method ignores any mouse presses until after the transition is over.

Also the reverse - reducing the width of the frame - doesn't work.

Does anyone have a solution I can use?

You could use timer and have two integers that store starting place and stopping place of movement.

Code:

---

Dim StartX As Integer
Dim EndX As Integer

Private Sub Form_Load ()
    StartX = 0
    EndX = ScaleWidth + Frame1.Width
End Sub

Private Sub Timer1_Timer ()
    If EndX > StartX Then
        If Frame1.Left < EndX Then Frame1.Left = Frame1.Left + 45
        If Frame1.Left < StartX Then Frame1.Left = StartX
    Else
        If Frame1.Left > EndX Then Frame1.Left = Frame1.Left - 45
        If Frame1.Left > StartX Then Frame1.Left = StartX
    End If
    Refresh
End Sub

Hope this helps,

That's cool - I didn't think of using the Timer.

However, I've modified the code so that the frame expands from 0 width to the full width of the screen. I should have mentioned that I have to avoid the flickering of the text in a label I put in.

Dim StartX As Integer
Dim EndX As Integer

Private Sub Form_Load()
StartX = 0
EndX = ScaleWidth + Frame1.Width
Timer1.Interval = 50
End Sub

Private Sub Timer1_Timer()
If EndX > StartX Then
If Frame1.Width < EndX Then Frame1.Width = Frame1.Width + 45
If Frame1.Left < StartX Then Frame1.Left = StartX
Else
If Frame1.Left > EndX Then Frame1.Left = Frame1.Left - 45
If Frame1.Left > StartX Then Frame1.Left = StartX
End If
Refresh
End Sub
