having some retarded dinput problems. my error code is that one of my parameters are invalid. the code is as simple as this:

DirectInput8Create(hInstance, DIRECTINPUT_VERSION, IID_IDirectInput8, (void**)&DInput, NULL)

im assuming that the bogus parameter is (void**)&DInput but i dont know why the only references i have made to the DInput variable is the creation of it:


the dinput.h header included alright too. everything in the code seems to be alright i dont know what the hell is wrong. maybe there are more headers i need to include or something. im using dx8

Posting the actual error message tends to be more helpful when solving problems than "my error code is that one of my parameters are invalid"... is it happening at compile time (a compiler error) or run time (a program error):

1. Make sure you are linking with dinput8.lib AND dxguid.lib

2. Make sure the DirectX SDK paths are at the *top* of the search order list in Tools->Options...->Directories

1. The hInstance is about all that could be wrong. Try replacing it with GetModuleHandle(NULL), if it works you''ve passed an invalid HINSTANCE.

2. Install the debug version of the DirectX SDK (plus make sure the runtime version is set to debug), and increase the debug output level for DirectInput in the DirectX control panel.
Debug the program and at your debug output window, the reason for the error *IS* there.

3. So many other possibilities such as bad creation of your window, other exclusive mode DirectInput app running, other instance of your app running, DirectInput on different thread to window creation. Thats why the debug output is so useful for tracking stuff down.
