Key Down event is not working

[honeyashu]

I've created a form in which to add an event to open a chm file on press of F1 i've included a code on keydown event of form but it is not getting fired even i've made the keypreviev property true.....

[code=vbnet]
Private Sub frmFacilityDeta ils_KeyDown(ByV al sender As Object, ByVal e As System.Windows. Forms.KeyEventA rgs) Handles MyBase.KeyDown
Try
If e.KeyCode = Keys.F1 Then
Globals.ShowHel pMe(Me)
End If
Catch ex As Exception
MsgBox(ex.Messa ge, MsgBoxStyle.Inf ormation + MsgBoxStyle.OkO nly, Me.Text)
End Try
End Sub
[/code]

Well I don't use VB, but have you checked that you have added the event handler to the actual form?

frmFacilityDetails.KeyDown += new KeyEventHandler(frmFacilityDetails.frmFacilityDetails);

or the VB equivalent.

Yes i've added the handler 'Handles MyBase.KeyDown' ... this way it is handled in VB.net... thanks but any other suggestion...

I think the problem is

Globals.ShowHel pMe(Me)

Try replacing it with Msgbox("Test") and see if that works. If not, please post the version of VS you're working with.

Globals is a class i've defined to incorporate all global functions... so this is not the problem i think... well this code is working fine with few other forms but in few not........
Any Suggestions...!

I am thinking that something other then the Form object is getting the focus and taking the keydown events and not sharing them with the form.
Have to checked to see if that function receives any other keys?

I believe there is also some funkiness if you have F1 set as a neumonic anywhere on the form.

as per the code i 've given only F1 key in the limelight & also didnt used it anywhere else.....
How can i check that focus is going where since debugger is also not activating any event .... and thus i m unable to trace it....

Hmm, have you tried handles Me.Keydown and not MyBase.KeyDown?

What other controls are on the form? Maybe a textbox has the focus?
