    Graphics problem with Borland C++

    I'm using Borland C++ 5 and have downloaded lots of peoples source as examples. Everytime though that something has to be run in DOS the text is messed up. It will have the text and in between it it's like it's pixilated. Is there a way to correct this or is it just because these programs were written to be run in pure dos? I'm running this on windows XP. The graphics are fine it's just the text thats screwed up ! ? ! ? !

    Are you using a laptop/notebook ???
    Tried 'propeties' -> compatibility ???

    I'm running this on a desktop PC. The graphics card is the one that came with the PC (I bought it back in 2000-1). I've tried different compatibility modes but no luck. I'm guessing it's maybe a driver issue with my graphics card? Maybe I ought to just suck it up and focus on 3-d Programming Anyhow I'd like to know if anyone knows of a way to get this to work. It's just inbetween the text that this "pixalation" (I can't thionk of any other way to describe it) happens. Oh, and numbers won't display but this isn't true for all of the programs I've compiled. Anyways this kind of sucks and like to know (if possible) how to fix it.

    I have no idea what's causing the problem...

    I'm using Borland C++ 5... something has to be run in DOS...
    Is Borland 5 a true-DOS compiler? You can use a modern Windows compiler (Dev-C++ or Visual C++, etc.) to make text-based programs. These are called Win32 Console applications.

    If the example code is Standard C++, it should compile and run just fine. That's the whole idea of a standardized language and portable code! But, it's actually unlikely that any randomly downloaded code is standard compliant...

    I had I had an older version but it was turbo c++ I think ???
    It worked without problems.

    It's not necessarily, but you can tell it to compile the code with the BGI library and create an EXE that will run in a DOS Shell. That's what I've been doing. I wanted to try and get it in a window and not a full screen to geta pic of what's going on. The prgrams run fine as far as graphics are concerned (they use graphics.h so I can't use Dev-C++ or VC) it's just text that gets weird and it's only inbetween the words of the text. Oh, these are not purely text based programs either. (ie. I had code for tetris and the blocks are fine, sound is fine, but the friggin' instructions on the LH side of the screen had that crazy pixel thing inbetween the words)

    arjunajay- are you aware of anyplace to download a Turbo C++ compiler I'd like to see if it would work with that. I've only been able to find Turbo C (no ++ )

    Anyhow, thanks for the replies !

    Here's a program that I compiled in Borland 5 with out a problem except that when I run it it has the pixalation problem that I've been explaining in one part. The initial menu that pops up is fine all the text is readable and looks normal. However if I choose option one, when the text "Please press a key to continue." appears in between each word is the "pixaltion" I've been talking about It's just really annoying and I was wondering if there was a way to get rid of it. Thanks.

    I'll give this one last shot then let it die. Has anyone tried to compile the ^^^^^^^above ^^^^^^^ code, and if so did you have any problems as far as text display goes?

    Try running the executable through a DOS emulator. I personally like DOSBox.

    I have no idea why you are getting this problem under the console. Never seen a console behaving like that. But that dos.h include is probably why.
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    Thanks Mario F. I hadn't considered that I'm Running this on XP so running in on an emulator is def. worth trying. Hope that works if not . . . well it is Microsoft (like they really care)

    Just tried out the program with dosbox and no problems. Evidently it was just the way XP emulates DOS that was screwing everything up. I'm Def. Happy Now.
