Maybe stupid question but...

Well i am sorry but i am trying to add a hook using SetWindowsHookEx
so here is what i have
Myproc:

LRESULT CALLBACK ChookDlg::MyPrc(int nCode,WPARAM wParam,LPARAM lParam){//...}

and my function

g_hHook=SetWindowsHookEx(WH_GETMESSAGE,(HOOKPROC)&ChookDlg::MyPrc,NULL,dwID);

when i try to compile it gives me an error
error C2440: 'type cast' : cannot convert from 'overloaded-function' to 'HOOKPROC'
None of the functions with this name in scope match the target type
I don't know what to do
Hmm i saw somewhere that it needs to be static but i need to use some variables of this ChookDlg and i can't (

Your problem is probably that you haven't made MyPrc a static member function. You can't use a non-static member function for your hook procedure because its argument list won't match what's required; a non-static member function receives an additional parameter implicitly, the this pointer. To illustrate:

class C
{
public:
    LRESULT CALLBACK HookProc1(int nCode, WPARAM wParam, LPARAM lParam);
    static LRESULT CALLBACK HookProc2(int nCode, WPARAM wParam, LPARAM lParam);

    // ... rest of your class here...
};

// ... more code here...

SetWindowsHookEx(WH_GETMESSAGE, C::HookProc1, NULL, dwID);  // ERROR: function is not of the correct type
SetWindowsHookEx(WH_GETMESSAGE, C::HookProc2, NULL, dwID);  // OK: static member functions work fine

yeah my problem was that i couldn't use my member variables but i found a way to fix that 10x anyway
