How to send message to another program?
-
I can get the handle of the dialog and the ID of the edit control. But the edit control only has ID, not caption. I do use GetWindow() to enumerate the desktop windows. It's a good way that can replace FindWindow function. My problem is I don't know how to use ID of the control to get the handle. I tried several functions, as GetDlgItem, GetDlgCtlID,... Could you give me further information? Thanks a lot. Richard Woo No pains, no gains.

I don't know why it works! Just before I sent you the 2 apps, it showed "Not Found". HWND g_FindSpecialControl(LPCSTR lpWndCap, int nIDDlgItem) { HWND hWnd; int nID; hWnd = FindWindow(NULL, lpWndCap); if (hWnd == NULL) return NULL; hWnd = GetWindow(hWnd, GW_CHILD); while (hWnd != NULL) { hWnd = GetWindow(hWnd, GW_HWNDNEXT); nID = GetDlgCtrlID(hWnd); if (nID == nIDDlgItem) return hWnd; } return NULL; } It's strange!

Hi, I tried another way and it did work! I used EnumChildWindows function to enumerate all child windows of the dialog and I could get the handle of the edit control through a callback function. Thanks for help. Richard Woo No pains, no gains.
