PreTranslateMessage: how can I get the handle of the edit box the cursor is in?

[Erich J. Ruth]

Let's say the user has their cursor in edit box
IDC_EDIT1. How can I write an if-statement saying

if (cursor in IDC_EDIT1) MessageBox("IDC_EDIT1");

while if the cursor is in edit box IDC_EDIT2, how
can I write:

if (cursor in IDC_EDIT2) MessageBox("IDC_EDIT2");

I am trying to get the handle from an edit box and
I am absolutely stuck and appreciate, as always, any
response any one can give me.

Hi,

If it's the caret cursor you are interested in (i.e. which edit control has input focus) you can find out which by code like:


CWnd *pWnd=GetFocus();
if(pWnd)
{
TRACE("Focus in control %d",pWnd->GetDlgCtrlID( ));
}

(but see documentation on GetDlgCtrlID() to see when it's valid). Also, if you put the code in a button handler or similar then focus will have switched to that before it runs, so it will always give that control's id.

If its the mouse cursor you're interested in (as opposed to the caret in edit boxes), you can try:POINT point;
::GetCursorPos(&point);
CWnd *pWnd = CWnd::WindowFromPoint(point);
