Sending ALT-N to top level window

[Gregery D Engle]

How can I send ALT-N to current window?

Thanks

SendMessage hWnd, %WM_CHAR, wparam, lparam

Michael,

That's pretty basic but I wanted to know how to send it to the
top level window or all windows. I've tried this:

SendMessage %HWND_BROADCAST, %WM_CHAR, 78, 29

Doesnt work. Basically I'm wanting to simulate a remote
installation of a setup program and it prompts for a user to
press next and that is the only prompt. so I need to simulate
ALT-N on the top level window.

As far as I know, it's not possible (or even a good idea ) to "broadcast" a keystroke to multiple windows in one step.

Have you looked at the keybd_event API? That is the most reliable way to send a keystroke to the window that has the foreground because it is independent of the target app. It will work for GUI-style apps, console apps, DOS apps...

For a complete example search the BBS for keybd_event.

What's about
hwnd = FindWindow(windowclass, windowcaption)
hwnd = FindWindowEx(hwnd, 0, "Button", "&Next"

SendMessage hWnd, BM_CLICK, 0, 0

That might work too, but it would be limited to English versions of Windows.

Hmmm... On the other hand, so would Alt-N, probably.

There is a magic Keybd_Event (for roreground window).
But better to start Spy++ and to look WM_COMMAND.

Um, wouldn't "broadcasting" a keystroke assume that all Top-level windows are currently in a state such that they are even looking for that key?

I can personally assure you that I have an application I have written which does NOT look for alt-n on any screen.

In your case - a "remote install - I think a couple copies of PC Anywhere at about $150.00 per out to handle the remoteness a lot quicker and less expensively than trying to find a code solution...

Michael,

I mean a silent install. I have 80 computers to upgrade in a
few hours. Much easier to simply put something in the login
script.

According to Jeffery Richter and Jonathan Locke in their Book Windows 95 A Developers Guide
The only fool-proof method of sending keystrokes is to use the Journal PlayBack Hook.
