请教一下关于处理消息的

左右是爱

注册消息处理方法后，它执行完总是有错误提示：
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call.  This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

并且 MessageFunction得到的参数值都是
lParam=1242076
wEvent=62428
wError=18
不知道如何写才对？

代码大概如下
#define  My_Message (WM_USER +2)
WORD          wEvent, wError ;
bool CALLBACK BtnDown_EventBtnClick(HELE hEle,HELE hEventEle)
{
        HWND hWnd=XWnd_GetHWnd(hWindow);
         SendMessage(hWnd,My_Message,(WPARAM)-1,(LPARAM)-1);
        return true;
}

void CALLBACK MessageFunction (HWND hwnd,UINT msg,WPARAM wParam,LPARAM lParam)
{
        wEvent=WSAGETSELECTEVENT(lParam);
        wError=WSAGETSELECTERROR(lParam);
        MessageBox(NULL,L"Hello",L"title",MB_OK);
}

int APIENTRY _tWinMain(HINSTANCE hInstance,  HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{

……
        HELE btnDown=XWnd_GetEle(hWindow,100100);
        //注册事件
        XEle_RegisterEvent(btnDown,XE_BNCLICK,BtnDown_EventBtnClick);
        //注册消息
        XWnd_RegisterMessage(hWindow,My_Message,MessageFunction);

……
}

自定义消息,函数格式:
bool CALLBACK WndOther(HWINDOW hWindow,WPARAM wParam,LPARAM lParam);
