SendInput()?

I've looked up API for SendInput(); and I don't really think
this is what I'm looking for.

I have two processes running.
1. Some windows App.
2. My programmed app.

I would like my programmed app to send a string of text
to a window app.

Is SendInput() the only way to do this?
SendInput will only allow one VK_CHAR at at time.

Any other way besides COM+.
I would like to stick to Win32 API if possible

Thanks

if you know the hwnd of the window you want to "send text to" you can do a PostMessage() to it. depending on what you want the results to be you will have to know how the window responds to the given message.

But PostMessage only send WM_messages
ie: WM_CLOSE etc

I need to send an actual char *msg = "blehbleh";

um, buddy, I think you're confused. Are you talking about a windows msg (WM_WHATEVER) or something completely defferent?

It seems to me that you are not simply se3nding text to an app....but you also want to add text to the display......(just like as I am adding text to this edit box by typing the keys on my keyboard)

If this is the case, and the control you want to add text to is an edit or rich edit, you should find the handle to the actual control (not the main window) and add text with a WM_SETTEXT message......if its something else entirely like MSWord, then perhaps you could simulate keystrokes with messages to fake keypresses.

Either way, try get Spy++ (it comes with VC++). This tool allows you to lookup control and window handles and inject a hook into them to see what messages are posted to a window

look up WM_COPYDATA. This should solve your problem

See this page under PUSHKEYS. This is a port of the vb statement sendkeys in C.

This is a similar more advanced version in C++.

Cool!

hi fordy, i never had any use for spy++, but i checked it out,
and its such a great shortcut tool.

but how come it doesnt have ,info for all the programs on my system?

for desktop, if i want to color the desktop without the use of
SetSYSColor can i simply subclass the desktop window class proc info in spy++, to do the same? how about rearanging icon or the size of desktop(rect)?

but for desktop WNDPROC , it doesnt provide any info.
:confused:

You can use spy to get a handle to the view window that makes up the desktop.....and indeed the systray and the taskbar.....

But if you want to control the icons your better off using the com interafce - IActiveDesktop as this allows you to control how the desktop is laid out.

For changing the display size try ChangeDisplaySettings()

Oh...almost forgot - and to get the WNDPROC of a window - GetWindowLong()

Thank You all

Isn't WM_COPYDATA only from windows CE?

nope, it works for all windows that I'm aware of. (at least since 16 bit)
