error C2664: 'SetWindowsHookExA' : cannot convert parameter 2 from 'long (int,unsigned int,lon

[snollow]

请问这是一个什么错误？怎样解决？

[rabo]

第二个参数是你的回调函数名字啊。

[snollow]

我的函数原型是这样
LRESULT WINAPI KeyProc(int nCode, WPARAM wParam, LPARAM lParam)
glhHook=SetWindowsHookEx(WH_KEYBOARD,KeyProc,glhInstance,0);
是怎么不行啊！！

[jian]

LRESULT CALLBACK KeyProc(int nCode, WPARAM wParam, LPARAM lParam)
试试看

[jian]

glhHook=SetWindowsHookEx(WH_KEYBOARD,（HOOKPROC）KeyProc,glhInstance,0);

[DoubleJiang]

将
我的函数原型是这样
LRESULT WINAPI KeyProc(int nCode, WPARAM wParam, LPARAM lParam)
glhHook=SetWindowsHookEx(WH_KEYBOARD,KeyProc,glhInstance,0);
改成
LRESULT CALLBACK KeyProc(int nCode, WPARAM wParam, LPARAM lParam)
glhHook=SetWindowsHookEx(WH_KEYBOARD,KeyProc,glhInstance,0);

[zangyong]

参数用的不对吧

参考msdn

很容易解决的

[snollow]

我是这样设的glhHook=SetWindowsHookEx(WH_KEYBOARD,KeyProc,glhInstance,0);

[zangyong]

LRESULT WINAPI KeyProc(int nCode, WPARAM wParam, LPARAM lParam)


你的函数原型错误

应该向上面那样

[sillyou]

改成这样：
glhHook=SetWindowsHookEx(WH_KEYBOARD,(LPTHREAD_ROUTLINE)KeyProc,glhInstance,0);

[jian]

glhHook=SetWindowsHookEx(WH_KEYBOARD,（HOOKPROC）KeyProc,glhInstance,0);
试试看？

[snollow]

我改成拉
LRESULT CALLBACK KeyProc(int nCode, WPARAM wParam, LPARAM lParam)
glhHook=SetWindowsHookEx(WH_KEYBOARD,KeyProc,glhInstance,0);
还是出现

error C2664: 'SetWindowsHookExA' : cannot convert parameter 2 from 'long (int,unsigned int,long)' to 'long (__stdcall *)(int,unsigned int,long)'
None of the functions with this name in scope match the target type

[snollow]

我改成 glhHook=SetWindowsHookEx(WH_KEYBOARD,(HOOKPROC)KeyProc,glhInstance,0);
可还是
error C2440: 'type cast' : cannot convert from '' to 'long (__stdcall *)(int,unsigned int,long)'
None of the functions with this name in scope match the target type
