Looking inside a DLL

[Larry Westrick]

Where does one start to see the code generated by PB6.0 in a dll. I know that the dumpbin utility will disassemble the entire dll but how do I find the entry points etc...

Before Lance asks - I'm would like to do this so I can see how different programming styles affect the resulting DLL

Ok If I understand what you are asking, you want to see the assembly code that powerbasic produces.
For that you could use a debugger. Not the one supplied with PowerBASIC though because that will not show the assembly code. If you have VC++ it comes with a debugger that will do it.
Also Borland Turbo Assembler comes with a nice debugger.
I am sure if you searched Yahoo you would find a lot of hits.
And I am sure that someone else on this board could suggest some too. Or maybe other ways of doing what you are asking.

Ok I just read your post again. You want to see the compiled code for a specific procedure in a DLL. I way I have done this is to create a EXE that calls the specific function in a DLL then I run the EXE in TD32 (Turbo Debugger32) and that lets me jump to the DLL and setup break points and also shows the Assembled code.

The best disassembler that you need is w32dasm. You can find it at
protools.cjb.net, there are also many other very usefull programming tools.

Thanks for the Help. I wrote a C program that called the various functions in the DLL and used the C++ debugger to look at the resulting code. I haven't tried the other disassembler yet, I will when I get a chance.

Where on the web could I find the 386/Pentium Instruction Set? I stopped programming in assembler when the 386 came out so my reference material is very dated.

Ok for the asm instructions you can check out different links, I think that the link I gave also has some asm helpfiles, otherwise check out these two links:
http://packetstorm.securify.com/programming-tutorials/ http://www.multimania.com/mrcrimson/

Also w32dasm is very clear and is very easy to read even if you know asm just a little.
