Okay, os heres the new problem.
Hello World shows up, but the window is invisable, and please do nnot tell me to paint it in, its futile that I be able to see the exit button, and other buttons
Thanks for anyone who helps, I figured since this was a different question it belonged in a different thread.

well it could be written a little better then. your problem might be in the unneccesary code
I am just starting in windows applications, I am learning from CPLUSPLUS.com, they make allot of errors >.>
Perhaps you should try out Visual Basic. It's specifically designed to make Windows...well...windows.

DTS you can't just tell people do do problems in Java when people are in a C++ forum. What does that make us look like. O_o
Anyway Johnny you should use code tags, then we can help a little more.
Also, cplusplus.com isn't making a lot of errors, it might just be you.

yes you can. c++ isnt an end all language. the program he is trying to do is very simple in java.it would be wrong to tell people to only program in one langauge

I know, but what if it requires as much speed as it can get? What if he's planning onintegrating it with assembly because it is a gui for a large database?
Not saying he is though.

It was me, still not exactly sure what I did wrong, but I copied and pasted there code and tested it, it worked fine. I have just copied it wrong somewhere, although I am not sure where.
I believe CeateWindowEx was failing, testing a window handle like
if(!hWnd) doesn't work AFAIK.
