get text under my mouse

[pherweg]

Hi,

when i do a left click on my mouse, i need to copy the word under my mouse into clipboard.

I saw this on babylon translater, which allows the user to click on a word (in any application) and then shows a translation of this word.

How can i do this?

I use a system wide hook do receive the click message, then i use WindowFromPoint to get the HWND.
But how do i get the word under my mouse (WM_GETTEXT doesn't work)?


Thanks
Peter

Use the hook function on WndProc()
in this case when you receive the WM_LBUTTONDOWN you know window handle and message GetWindowText()
for example

LRESULT CALLBACK CallWndProc(int nCode, WPARAM wParam, LPARAM lParam)
{
CWPSTRUCT* pWnd = (CWPSTRUCT*)lParam;

switch(pWnd->message)
{
case WM_LBUTTONDOWN:
{
int iLen = GetWindowTextLength(pWnd->hwnd) + 1;
LPTSTR s = (LPTSTR)malloc(iLen);
GetWindowText(pWnd->hwnd, s, iLen);
////......
free(s);
}
}

return CallNextHookEx(NULL, nCode, wParam, lParam);
}

Good luck.
