[Solved] Win32 API hook implemenation problem.

zither

Dear all,

I write an application to use with win32 keyboard hook implementation in pure Qt not using external dll.
I face a problem with GetKeyState function. In Visual Studio, it can achieve with like that

@BYTE keys[256];
GetKeyboardState(keys); //WINUSERAPI SHORT WINAPI GetKeyState(int); @

But when I try it in Qt, return error like that,
@BYTE keys;
keys = new BYTE[256];
GetKeyState(keys);
// error: invalid conversion from 'BYTE' to 'int'@

Is GetKeyState(int) need to examine all 256 keys?
How can I solve that problem?

Thanks

You are using two different functions in your example. The first one is using
GetKeyboardState
the second one is using
GetKeyState

GetKeyboardState is using a pointer to bytes and GetKeyState is having an int as argument.
