I don't know your answer but one point is that if you want to display drawing from autocad (.dwg files if I understood it well), you'll need a libraray (or whatever) that can read these files.
So, maybe that could be a good starting point: finding how you will load these files.

Does AutoCAD have some sort of ActiveX control? If not, you'll need to convert the drawings to something that Windows can recognize (e.g., GIF, BMP, JPEG) natively.

There are several ways of displaying a .bmp file on a dialog. For example, use a static control with the SS_BITMAP style.

But it is possible to display no of .bmp file ??( I have appr more than 100 .dwg file)ie if i will convert it from .dwg to .bmp then i have more than 100 BMP file..

If you needed to show more than one at a time, you could use a list box with the LBS_OWNERDRAWFIXED style.

Hello,

In order to read AutoCAD Dwg files you need a library, DWG files must be analysed in order to write a reader and it should work for different versions (Since it is not documented). You can export drawings as DXF and read it. DXF Format is documented and there are libraries that you can use (DICE, one in OpenSceneGraph)or you can write on your own. However, there is also a library which does that for you (but you gotta get a license) searh for dwg library on Internet.

By the way, Autocad can export bitmap with bmpout command.

As suggested earlier, you may use ActiveX, i dont have much experience on this, however that might be possible, Autocad provides libraries and controls for .NET VB/VC++ applications, search for ARX but your AutoCAD and Visual Studio versions must be compatible. (For example Autocad 2007 needs VS2005)

Hope this helps.

Bekir.

Studio amd asm code

Hey.

This seemed like the most relevant forum but sorry if it isnt.

I am using Visual Studio 2003.NET and would like to know how can I get it to compile files written in x86 assembler code alongside my project.

I have tried adding "E:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\ml.exe" /c /Cx /coff $(inputpath) as a custom build step with the output set to $(InputName).obj. But every time i build i get unresolved external.

At the top of my C++ file i have extern asmfunction.

Any one spot any beginners pitfalls I may have stumbled blindly into.

Cheers.

Dan.

Why are you using the command line ?
Build the asm to a lib using a separate project, and then bind all projects in the workspace.

Hey.

Thanks for the help but that is the problem - i am unsure how to compile the asm code.

Thanks for any help.

Regarding what (e.g., functions in your .asm files, or in your .cpp files)? Are your .asm files being compiled into .obj files?

Hey thanks for the reply.

The problem is that I have an asm function that writes to video memory called ClearRectangle(BYTE left, BYTE top, BYTE right, BYTE bottom, BYTE colour).

I attempt to compile this with ml.exe (as per the build step i talked about in my first post).

I also have a cpp file that simplified looks like this:

typedef char BYTE;
extern ClearRectangle(BYTE left, BYTE top, BYTE right, BYTE bottom, BYTE character, BYTE colour);

int main(void)
{
ClearRectangle(0, 0, 80, 25, 0xDB, 0x1);
}

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)"

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.

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