在windows server 2008上，.net 应用程序调用c++ dll时会发生崩溃本文来自http://blogs.msdn.com/asiatech/default.aspx 上我写的一篇文章： .NET application may crash when calling function from native C++ dll Symptom===========Customer built an ASP.NET web application u 阅读详情

BOOL BoolRegHotkey;
HWND W_Hwnd;
int ID_HTK;
int OldProc,ScrollProc;
extern "C" _declspec(dllexport) BOOL __stdcall RegHotKey(HWND Hwnd,int ID_HOTKEY,UINT Key)
{
OldProc = SetWindowLong(Hwnd,GWL_WNDPROC,ScrollProc);
if (RegisterHotKey(Hwnd,ID_HOTKEY,MOD_CONTROL|MOD_ALT,Key))
{
return true;
W_Hwnd = Hwnd;
BoolRegHotkey = true;
ID_HTK = ID_HOTKEY;
}
return false;
BoolRegHotkey = false;
}

extern "C" _declspec(dllexport) BOOL __stdcall UnHotKey(HWND Hwnd,int ID_HOTKEY)
{
if (UnregisterHotKey(Hwnd,ID_HOTKEY))
{
return true;
}
return false;
}

LRESULT WndProc(HWND hwnd, UINT message, WPARAM wParam,LPARAM lParam)
{
hwnd = W_Hwnd;
switch (BoolRegHotkey)
{
case WM_HOTKEY:if (BoolRegHotkey)
{
ShowWindow(hwnd,SW_HIDE);
}
else
{
ShowWindow(hwnd,SW_SHOW);
}
BoolRegHotkey = !BoolRegHotkey;
return 0;
break;
case WM_DESTROY:UnregisterHotKey(hwnd,ID_HTK);
PostQuitMessage(0);
return 0;
break;
}
return CallWindowProc((WNDPROC)OldProc,hwnd,message,wParam,lParam);
}

代码如上，我使用程序调用这个DLL的时候程序直接崩溃，谁帮我修改下啊！到底哪儿的问题
我想实现的功能是热键注册，并且通过热键隐藏和显示窗口
