How do you center controls on a form in VB.NET?
Help! I'm just getting back into programming. I thought I would go with the new VB.NET versus the VB 6.0 that I was used to. How in the world do you center controls on a form in VB.NET? VB6 makes it easy with the screen.width formulas.
All the same properties are still there. Here's the code that shows how to keep a button control named buttonMain centered in a form:
Private Sub Form1_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
CenterButton()
End Sub
Private Sub CenterButton()
buttonMain.Top = (Me.ClientSize.Height/2) - (buttonMain.Height / 2)
buttonMain.Left = (Me.ClientSize.Width/2) - (buttonMain.Width / 2)
End Sub
Private Sub Form1_Resize(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles MyBase.Resize
CenterButton()
End Sub

Private Sub hCenterControls(ByVal ctrl As Control)
ctrl.Left = (Me.ClientSize.Width / 2) - (ctrl.Width / 2)
End Sub
Private Sub hCenterControls(ByVal ctrls As ControlCollection)
For Each ctrl As Control In ctrls
ctrl.Left = (Me.ClientSize.Width / 2) - (ctrl.Width / 2)
Next
End Sub
Granted, centering a group of controls can get messy. You'd have to write additional code to prevent controls from being on top of each other. In other words, keep the same amount of space that had between each other before you moved them.
