query on toolbar control

[zarina]

hi,
I hav used a toolbar control in my application. On the toolbarbutton click event i need to open the respective forms.Its works fine but the problem raises when there is a need of closing my sub forms.THE toolbarbutton click actually hides the sub forms.I wan to know how to close the sub forms.

First let us know how you open it as it much depends how you will close it ... i.e. if your app is MDI and not SDI you would refer differently to the form. Also post the code that hides the form

this is the code snippet i hav used in my application.with the properties in the form1,form2,form3,form4 as maximizebox,minimizebox,controlbox to be false and windows state to be maximum

Dim frmobj1 As New form1
frmobj1.MdiParent = Me
Dim frmobj2 As New form2
frmobj2.MdiParent = Me
Dim frmobj3 As New form3
frmobj3.MdiParent = Me
Dim frmobj4 As New form4
frmobj4.MdiParent = Me

Dim ButtonPicked As ToolBarButton = e.Button
If (ButtonPicked.Equals(ToolBarButton1)) Then
frmobj1.Show()
ElseIf (ButtonPicked.Equals(ToolBarButton2)) Then
frmobj2.Show()
ElseIf (ButtonPicked.Equals(ToolBarButton3)) Then
frmobj3.Show()
ElseIf (ButtonPicked.Equals(ToolBarButton4)) Then
frmobj4.Show()
ElseIf (ButtonPicked.Equals(ToolBarButton5)) Then
End
End If


on the click event of the toolbarbutton2 i get my form2 opened its necessary for me to close that form.how can i close it wen i click al other buttons.

Do you really want to Close it? With that code, if you Close it and then press the corresponding ToolBarButton again you will get an unhandled exception.
