In VB.OLD you cannot change the ShowInTaskBar property at runtime as you can in VB.NET. If you put this code in your form you can change the setting.

Option Explicit Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long Private Const GWL_EXSTYLE = (-20) Private Const WS_EX_TOOLWINDOW = &H80 Private Sub SetStyle()     Dim lWindowStyle As Long     lWindowStyle = GetWindowLong(Me.hwnd, GWL_EXSTYLE)     lWindowStyle = lWindowStyle And WS_EX_TOOLWINDOW     SetWindowLong Me.hwnd, GWL_EXSTYLE, lWindowStyle End Sub Private Sub Form_Initialize()     SetStyle End Sub

This here will remove the taskbar button of your form when the form is initialized. It could be useful if you want to provide your users with an option particularly in MDI applications. In an app that I worked on a long while ago some users wanted the MDI childs button in the taskbar and others did not. So I gave them an option which would take effect the next time they opened an instance of the child form.
I hope someone finds a use for this technique.

One thing I havn't been able to do however is that  I have not fount a way to change this setting without unloading the form first. Happy coding...

Hi

In VB 6.0 u can do the same thing by setting the showintaskbar property of the form to true or false. I couldnt understand the reason for using the APIs. Also what do u mean by VB.OLD? Please explain.

thanks in anticipation

He ment exactly what he said. You cant change ShowInTaskBar property AT RUN TIME in VB.OLD = Previous VB versions. So, to do it at run time, you need to use API BEFORE the form is loaded, or it will not take effect.

Thanx Goran,

that is exactly what I meant. VB.OLD refers to versions of VB before VB.NET. VB.NET allows you to change this at runtime inherently but in VB.OLD you have to do it at design time or use this (or similar) code.
