teacher assigned task, but I feel impossible, I wrote a part of the source code, can obtain the application and system program of a part of the title, which is unable to get to the general application of handle, wish you a great god some directions, I hope that other applications can be taken to:
#include
#include


The # pragma data_seg (" mydata ")
HHOOK h_gHook=NULL;
HHOOK h_gHook1=NULL;
HWND g_hwnd=NULL;
LPMOUSEHOOKSTRUCT pMouseHook=NULL;
HWND glhPrevTarWnd=NULL;//referred to in the last time the mouse window
HWND glhDisplayWnd=NULL;//edit box shows the target window handle
HINSTANCE glhInstance=NULL;//DLL instance handle
Char strMsg [100]={0};
# pragma data_seg ()
# pragma comment (would, "/section: mydata, RWS")

Int nCode,
WPARAM WPARAM,
LPARAM LPARAM

}

//get the application window handle

CodePudding user response:

Word is used more hook API: from screen TextOut

CodePudding user response:

That can source to come over, I'm a freshman, found there are some about the word from the screen, but most of them were transferred to an article, but I also copy, the result is always wrong, a little error is fatal to me, because the other is too complicated, can't debugging

CodePudding user response:

This kind of question, generally do not give a complete source code, are generally not prompt you to how to solve the concrete solution depends on yourself,

CodePudding user response:

The original poster can be called powerword DLL CSDN offer interface specifications, search, and to write their own must be HOOK system function,
