SendMessage

How do you send an "ENTER" to an external's (another app) textbox without using SendKeys?. TIA,

VB Code:

SendMessage hWndTextbox, WM_CHAR, (vbKeyReturn), 0

try the keybd_event Function

I could not make it work.

Try WM_KEYDOWN, followed by WM_KEYUP, using VK_RETURN (vbKeyReturn).
so

VB Code:

Const WM_KEYDOWN = &H100
Const WM_KEYUP = &H101
'--------
SendMessage hWnd, WM_KEYDOWN, 13, 0
SendMessage hWnd WM_KEYUP, 13, 0

Didn't work either. Besides... I'm having problems finding the handles automatically. Any ideas what could I be doing wrong?

Even harder if we can't see what you are trying to do.
It won't work if you use the wrong handle. :)

keybd_event is the same as a SendKeys since they both require the receiving app to have focus.

Try using PostMessage maybe.

Since I cannot get the handle (the last step is the problem) I'm inputboxing it. I can write some text to the textbox... so the handle is inputted (manually) correctly, but the ENTER is not working. This is my code:

VB Code:

tWindow = FindWindowEx(lhWnd, 0&, "AfxControlBar42s", "Watches")
    tWindow = FindWindowEx(tWindow, 0&, "AfxWnd42s", "Output Window")
    tWindow = FindWindowEx(tWindow, 0&, "Afx:400000:8", vbNullString)
    hWndTextbox = FindWindowEx(tWindow, 0&, "Edit", vbNullString)
 
    'hWndTextbox remains equals to 0.
 
    SendMessage hWndTextbox, WM_SETTEXT, -1, ByVal sMsg
    SendMessage hWndTextbox, WM_KEYDOWN, 13, 0
    SendMessage hWndTextbox, WM_KEYUP, 13, 0

The message (sMsg) is written correctly, but the ENTER does not work.

I cannot use SendKeys because when this other app is activate, the focus is not on the textbox it should.

Oh its a textbox control. Then it doesnt accept an enter as a valid character unless you have a multiline textbox. What control is supposed to receive the enter keypress?

Correct, thats why I mentioned that keybd_event will NOT work because of its similarities with SendKeys. ;)

Can't you just click on a button instead of pressing Enter?

The Edit class of window is a Textbox control and not a command button. ;) I am wondering myself where the enter keypress fits into this?

Im sorry, mine works for RTB's
