I have a login form for MySQL db, when i click log out from the MAin form, I make the log in form to show, but it doesn't stop someone from using the other forms, How do i make this form stand out on top of other form or make the system not usable unless one logs in.

Thanks in advance..

Since you are talking about forms, I assume this is WinForms?

If so then just use

if (myLoginForm.ShowDialog() == DialogResult.OK)
   {
   ...
   }

The ShowDialog method halts processing until the user has responded or closed the form.

"the forms you create in VB are WinForms? Well
am using this code:
Dim frm As New frmLogin
frm.MdiParent = Me
frm.ShowDialog()
When i add frm.ShowDialog(DialogResult.OK) it says it cant be converted to win32 forms"

Sorry - C# rather than VB:

Dim frm As New frmLogin
If frm.ShowDialog() = DialogResult.OK Then
   ...
End If
