Question

For my informatics studies I have to write a Space Invaders Clone using Windows API.

One of our tasks is to write and display a Highscore list which works very well.
If you have lost all credits you should be able to write your name into the highscore list (if you have enough points).
Windows API has no easy possibility to get a text input so I wrote an own version that works not as I want it to.
I use pName to write the name and save it into an array called “Name”.
This array is used to save the Highscore and the name together into the Highscore.txt.
The Saving progress is working fine so far.

But my problem now is:
I’m able to write letters but they’re sorted automatically.
So if i input: asdf
it is sorted: adfs

I can’t see any code that does something like that so where’s my fault?

Thank you guys!

            sprintf(Name,"%s", pName.c_str());
            TextOut(hdc, 50,250,Name, strlen(Name));

            return true;
}

Answer 1

I found a soultion that was pretty easy.
I made a big fault that I couldn’t see after hours of programming:
I initiate my string pName again ang again from the beginning. So I moved it to my constructor and now it all works fine.
To get a better sensibility, you have to change

(GetKeyState(VK_LETTER))

to

(HIWORD(GetAsyncKeyState(VK_LETTER)))

Now it works much better!
