Winapi在屏幕上使用MouseClick活动显示图标

在Winapi中，我看到了一种病毒，每当发生鼠标点击事件时（内部有白色X的红色），它在鼠标的X-Y上显示图标。每当我单击鼠标时，如何显示这样的图标？我知道如何使用setWindowShookex挂接鼠标。如下所示，是否有像Iconshow这样的功能。

HHOOK msHOOK;
//getting the icon let's say from a rc file
HICON redIcon; 
msHOOK = SetWindowsHookEx(WH_MOUSE_LL, mouseProc, NULL, 0);
LRESULT CALLBACK mouseProc(int nCode, WPARAM wPar, LPARAM lPar){
  IconShow(NULL, redIcon, xofMouse, yofMouse, 0);
  MessageBox(NULL, "Icon showed", "Cap", 0);
  return CallNextHookEx(NULL, nCode, wPar, lPar);
}
while(GetMessage(&msg, NULL, 0, 0) > 0){
  TranslateMessage(&msg);
}

谢谢
