F1 Key input

does any1 know how to get the prog to recognise F1 as an input button to so i can link in a help interface

cheers

Yes, it is very simple:

PHP Code:

---

//Inside the message switch in the main window loop
case WM_KEYDOWN:
    switch(wParam){
           case VK_F1:
                  //Do whatever
            break;
     }
break; 


---

One downside to this simple approach is that it will repeat the process every few milliseconds you hold the F1 key down. To correct that make a bool variable called F1pressed or something and set it to true at the end of the VK_F1 case statement, then code a WM_KEYUP the same as above just make it so it sets the bool variable to FALSE. Then set up an if statement around your help code to check if the bool variable is TRUE or not. I hope you get this!

What library do i need to include for WM_KEYDOWN, wParam and VK_F1?

cheers

That code is for Windows only.

If you wish to do this in DOS, you will need to write and INT 9 handler. Then you only need to check for the correct scan code for the F1 key (find a scan code table for the keyboard).

Thnx mate
