I have a form 'form1' with a textbox 'textbox1'. UseSystemPasswordChar=True because it would be a password field. When I turn on caps lock a warning message appears. I want to disable ONLY this one balloon!

I have this code, but it doesn't work! It looks like message number for EM_SHOWBALLOONTIP is not correct, but I can't find the good one.

Public Delegate Sub DeActivateEventHandler()
Public Class Form1
    Private Const ECM_FIRST As Long = &H1500
    Private Const EM_SHOWBALLOONTIP As Long = (ECM_FIRST + 3)
    Public Event DeActivate As DeActivateEventHandler
    Protected Overrides Sub WndProc(ByRef m As Message)
        If m.Msg = EM_SHOWBALLOONTIP Then
            RaiseEvent DeActivate()
        End If
    End Sub
End Class

Could you help please?

Solution 1

Add the following to the textbox key down event

If e.KeyData = Keys.CapsLock Then e.SuppressKeyPress = True

Solution 2

This won't work if caps lock is already on before some one clicks on the control which will show the message
