Question

c#钩子做了个程序怎么不能处理消息

下面代码有问题吗？截取不到WM_PAINT消息
还有要处理键盘消息应该怎么写
private int myhookproc(int code, IntPtr wparam, ref CWPSTRUCT cwp)
{

//下面三行能执行到
// Graphics ggp;
// ggp = Graphics.FromHwnd(hwnd);
//ggp.DrawString("jj", new Font("宋体", 10), new SolidBrush(Color.Gray), new Point(30, 30));

switch(code)

{

case 0:

switch(cwp.message)

{

case WM_PAINT://0x0000F:WM_PAINT，拦截

//do something
Graphics gp;
gp = Graphics.FromHwnd(hwnd);
gp.DrawString("jj", new Font("宋体", 10), new SolidBrush(Color.Gray), new Point(30, 30));

break;
case (int)MouseButtons.Left :
{
MessageBox.Show("JJ");
break;
}

}

break;

}

return CallNextHookEx(hookHandle,code,wparam, ref cwp);

}

郁闷，我C#已经忘 的差不多了，只不过是3年没编程而已。
