TAB Trap

[Phylum]

I am trying to capture the TAB key inside of a textbox. I used Key_Up, Key_Down and Keypress events to try an capture it. No go. Is there a way to do it?

sounds like a job for the api but.. i did find something interesting

 

check this out in the help files

http://ms-help://MS.VSCC/MS.MSDNVS/cpref/html/frlrfsystemwindowsformsuicuesclasstopic.htm

 

 

the Control.ChangeUICues method seemed to be of interest

i'm not sure what to do with it but you can always experiment

 

i had typed some big jerry riggin way of doing it, then i found this method. if you'd like to hear my jerry riggin way let me know, just provide more details about what you are doing with the tab key so i can get it right.

 

here is the extreme short jerry rig example

 

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

'use your imagination


End Sub

 

 

hope something in all of that junk helps

 

goodluck

Check out the IsInputKey method of the control, you might have to override that. If you're just trying to get the control to accept a tab as input, it should already have an AcceptsTab property.

Private Const WM_KEYDOWN As System.Int32 = &H100

Public Overrides Function PreProcessMessage(ByRef msg As System.Windows.Forms.Message) As Boolean
       Select Case msg.Msg
           Case WM_KEYDOWN
               Select Case msg.WParam.ToInt32
                   Case 9
                       'tab was entered
                       Exit Function

                   Case 13
                       'Enter()
                     
                       Exit Function
  
                   Case Else

                       MyBase.PreProcessMessage(msg)
                       Exit Function
               End Select

           Case Else
               MyBase.PreProcessMessage(msg)
               Exit Function
       End Select
   End Function
