[2005] Global Key hook Help

Hello all, HEre is my dilema. I have an application that will be running at the same time as another and what i want to do is to capture certain key combinations namely Ctrl + 1 through 0 and Alt + 1 through 0 and send them to my application running in the background instead of the current application. Through my searching I hav found many examples of Keyboard hooking that should do this, however I can't seen to get an to work. This is the class I am using to hook, but when i runs the chechHook function it says not hooked. Can anyone help me with what may be wrong? Thanks in advance
