Reading key presses in web page control

[mdean]

Hi,

I have a container with a several input fields (controls) on a web page. This has to act like a standalone app within the browser. One thing I want is, when the page loads, the user should be able to hit a function key and a vbscript on the page will redirect to another jsp page.

When I have an exe control, this is easy because the form can catch all of the key presses. But how can I set this up when I'm on a web page? Should my listener be in the container code?

Any help would be really appreciated,

Mike

Use the GetAsyncKeyState api function and put this code in a timer, and it will capture everything typed.

Private Declare Function GetAsyncKeyState _
Lib "user32" (ByVal vKey As Long) As Integer

Private Sub Form_Load()
Timer1.Interval = 1
End Sub

Private Sub Timer1_Timer()    
Dim i As Integer    
For i = 3 To 255       
If GetAsyncKeyState(i) Then Debug.Print Chr(i) 
Next 
End Sub

Matthew,

This is a huge help -- thanks so much. It looks like you're extremely confortable with this stuff; could I ask two more questions?

I can capture keystrokes now, but I also need to capture keystroke combinations, e.g. Alt-S. I understand how to register a hot key, so all I should need to do is register my combination and then listen for it in my timer listener routine, right? How exactly should the code look for referencing this event; obviously GetAsyncKeyState won't do.

My second and probably dilemma is, when I receive the right key I'm listening for, I need vbscript on the web page to do a redirect. How do I listen for my keystroke event on the page? I can raise an event right but then how is this event referenced on the page, i.e. how can I set up my properly declared control_event() routine?

Sorry to bother you again,

Mike
