Open help file from VB

In my app, when pressing F1 key the help file is displayed. However, when the "Tips of the day" form is displayed, pressing F1 does not do anything (in winzip, if "Tips of the day" is shown, pressing F1 key will show the help file as well)

What should I do to my "Tips of the day" to make it display help file when pressing F1 key?

Thanks

Hi
If the Tips of the day popup is a form (as against a pic box or frame) then it will have focus and the main form will not receive the key press event. U could make set the keypreview of the Tips form to true and check the keypress event also. NB If the tips of the day form is modal this can cause problems. A better way is to make the form modeless but always on top and then set it to 'not always on top' when the help file is loaded

I thought you only wanted to know wether you should check for a keypress in "Tip of the Day" form too.
you can use a timer on both form (main form and also Tip of Day form), and then use "GetAsyncKeyState" to see if "F1" is pressed. If yes, then you show the help file.
Here is how you use "GetAsyncKeyState" API:
VB Code:
```
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer
Private Const VK_F1 = &H70
Private Sub Timer1_Timer()
' This check to see if F1 is pressed
If (GetAsyncKeyState(VK_F1) <> 0) Then
'show the help file
End If
```
Hope that is a little helpful.
