Sending keystrokes to window?(PLEASE ANSWER!)

You can read my past 2 post, about the Window Manager. I have a question. How do I make an AOL Instant Messenger window type the text in an edit box from my program? It's not homework! I do self-created projects. I'm just really curious so please help! I know how to get a button click, too. When the user clicks the send button, how do I make an Instant Message window type the stuff in the EDIT box?

Hi,

Firstly you need to get a handle to the edit box in AOL IM, The best way to find a handle is buy Using FindWindow().

Once you have a handle simply send it the WM_CHAR msg with wParam containg the value of the keys that you want to be displayed.

Once AIM has recived this message it should display them automaticall, aslong as it was not created with a resource.

Code:

---

//second param = window title
HWND hWndAim = FindWindow(0, "AOL Instant Messenger");

if(hWndAim != NULL)
{
SendMessage(hWnd, WM_CHAR, wParam, lParam);
}

---

wParam Specifies the character code of the key.

That should be possible to adapt to work, i think anyway... as long as its not in VB which it may be.

Thanks

Hey SyntaxBubble, I see that you are making somehting that is similiar to a aim prog. Good Job.

Thanks, jinx. Anyhow, (TNT), does the WM_CHAR message have to send a seingle character at a time? Because I don't think it's working right.

Hi,

Yes WM_CHAR does deal with single key strokes. But you should be able to set up a loop to display a string, character by character in the other application.

There may well be a better way of doing this, this is just what came to mind.

Code:

---

char str[100] = "Display";
for(int i = 0; i < 7; i++)
{
//go through every letter in str and send it individually to aim.

}

---

Hope that helps

Ok, now say the screenname to send to is "abc_123", I use GetWindowText(); to get my edit box text, which is what to send. Could you post a code to how you would send them?
