Have you considered doing this via Win32? I'm not sure how it compares speed-wise, but you would get past this compiler/linker roadblock.

When i compile this i get ASM error LNK2019: unresolved external symbol "void __cdecl ClearRectangle(char left, char top, char right, char bottom, char character, char colour)"

Which indicates that the ASM's .obj file is not being linked. You'll need to make that change.

Hi
Win32 isnt really an option I am doing this as an exercise in asm.

How do i link in the obj file? I have looked at additional dependancies etc but am still not sure.

Thanks

This is a little OT, but is this from an older (256-color) DOS-based application? You cannot (easily) write directly to video memory from a normal Win32 application, so I am not sure that this will work correctly even after you resolve the linking problem. We have come a long way from the days of ModeX programming. Smile | :)

   It looks like a character-based operation, but I figured I would make sure - given that the function takes no parameter to indicate which console window to use, or what address to write to...

   Also, BYTE is normally typedefed to unsigned char.

   Peace!

Hi.

Thanks for the typedef suggestion.

I am porting some functions I wrote using Borland Compiler 4.0 (C/C++) (16bit).
They worked under windows 2k and windows XP. The screen memory location is within the function:- b800h that is then used along with an offset and simple maths to write chars at the correct positions.

I have quite a few asm screen related functions that need porting - this is just a practice so I think I will just continue to use BC v4.0

Thanks for every ones help.

Dan

Heh - I remember B800 quite well! Smile | :)

   I am surprised that things are working correctly writing directly to that address actually does anything under Windows, unless running in a DOS prompt, but now that I think about it, you are using character locations, so that actually makes a bit of sense... :/

   Good luck to you...! - If sticking with character operations, it might be worth investigating the Console functions. They are a bit of a pain in the ass to use, especially if doing anything in color, but they are the Win32 way of doing things...

   Peace!

Hi,If you are using VC8 see the CImage Class in MSDN.Using that you can get the Handle of JPEG and use it as BMP to display the image.

CImage m_Image;
m_Image.Load(yourfile);
m_Image.BitBlt(...);

Or you can use of GDI+

Japenese? If you are using Visual Studio 6, then you have to load all the unicode strings dynamically. Because VS6 is unaware of unicode. Otherwise, you could change the font to what you want from the "properties" of the dialog or control.

Hi All,

I'm looking for a portable C++ IDE to work with it anywhere. I came across Bloodshed Dev-cpp which uses Mingw but I have many problems with it. Now I wanna see if there is any other portable c++ compiler?

I don't think the IDE is cross-platform. It is just for windows as far as I know (but I might be wrong).

I know that Code::Blocks[^] is cross-platform and I heard a lot of good things from it. You should take a look at it (never used it myself).
