【转帖】使用createremotethread控制excel右键的源程序
利用CreateRemoteThread将dll写进excel.exe.利用SetWindowLong()改变excel中右键消息。dll源程序：#include <windows.h>
BOOL __stdcall DllMain(HANDLE,DWORD,LPVOID)
{
return TRUE;
}
/*
#pragma data_seg("shared")
#pragma data_seg()
#pragma comment(linker,"/SECTION:shared,rws")
*/
WNDPROC g_lpfnOldWndProc;
HWND g_hMsgWnd;
LRESULT APIENTRY HookExcelWndProc(HWND hWnd, UINT wMessage , WPARAM wParam, LPARAM lParam)
{
try
{
switch (wMessage)
{
case WM_RBUTTONDOWN:
MessageBox(g_hMsgWnd,"u click the r button","",MB_OK);
return 1;
break;
case WM_CLOSE:
::ExitProcess (0);
break;
default:
if (NULL == g_lpfnOldWndProc)
return DefWindowProc(hWnd,wMessage,wParam,lParam);
else
return CallWindowProc(g_lpfnOldWndProc,hWnd,wMessage,wParam,lParam);
}
}
catch(...)
{
}
return 0;
}
LRESULT __stdcall HookExcelRightMenu(HWND hwnd)
{
g_hMsgWnd = hwnd;
g_lpfnOldWndProc=(WNDPROC)::SetWindowLong(hwnd,GWL_WNDPROC,(LONG)HookExcelWndProc);
MSG msg;
while( ::GetMessage( &msg, NULL, 0, 0 ))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return TRUE;
}
