actually I have already done pong with opengl, how about breakout?

I am attempting to draw to a window using DrawText and WM_PAINT. I want to use the mouse and the WM_LBUTTONDOWN message. I understand that to actually draw to the screen one must use the WM_PAINT message. I am using the Win21 API. I am using this API because I want to learn how to program in windows better.

hey kathar thanks for the reputation boost, and to mhagain can you post some code.

I have done a great deal of research about game loops, message pumps, windows messages, windows threads and timer functions. I also read about splash screens and finite state machines.  I still want to erase text on the screen.  After much research I am still stuck on how to solve this problem. Google is my friend. Go easy on me I am attempting to ask better questions.  Basically I am confused about how to use game loops.My question is when in the game loop do you print text to the screen and then print black text to the screen. Fastcall22 gave me some code and a explanation on how to  use game loops I would like just little more information on how to use game loops.

My problem is that I can use dx9 to print text to the screen. I created a font and used the drawtext function to print text to the screen. What I want to do is that after the text is sent to the screen that the text would be cleared from the screen. Basically all I want to do is give instructions to the player on how to interact with the GUI and then to be able to play the game without text on the screen. This is something like a splash screen. I have tried printing text to the screen in red color and then printing the same text to the screen in black but it does not erase the text that is already printed there. I hope you can understand my problem and hopefully help me to solve. Let me know if need more information or code.

well thanks I like the thumbnail picture, and yes star trek rocks.

I am using the windows timer function to draw black text to the screen to cover up red text which I already drew to the screen.
I am trying to erase text for my  pong game.I have done a lot of research on this topic but I still need help.

case WM_TIMER:

  {

  switch(wParam)

  {

   D3DCOLOR fontColor = D3DCOLOR_XRGB(0,0,0);

   RECT rct;

   rct.left=200;

   }

   break;

  }

  return 0;

  }

yeah! I finally got my program to work!thanks for all the help.

I agree C# is nice and easy to use.

I prefer the o-reilly texts and others agree with me.they are very  books for reference.

So you just start the app, and wait 2 minutes, then it crashes?

yes I start the app and wait then it crashes.

well I learned c++ in university and it has been my main tool ever since,but c# is really nice too.

do you have yahoo messanger

I dont have a web cam either.
