[RESOLVED] DLL Injection [DLLMain in VB6] Help with .DEF File [HELP!]

[henriqueshb]

Hello guys!

I need some help in here, actually i need any help you could give me.

The thing is, I do know how to make an attached dll made in c++ startup, but in vb 6 I don't.

The only thing I know is that i need to create a file (that I DON'T EVEN KNOW HOW SHOULD BE NAMED) with the extension ".def".
It should hold some configurations about the linker and stuff...

One of that stuff is the "Exports" properties. There i should put the "DLLMain" function declared in my dll and then the magic will happen.
At list, thats what people say in some forums...

Basically i need to know how to create an injectable Dll, the porpouse is to run it in mine "Lost Source Code" .exe. I added a new window that do some cool stuff that i wanted to be shown there.

Any tip of the name? content? anithing?

And sorry for the POOR ENGLISH!

Thanks in advance.

a .DEF file is simply a file you use for the compiler to export unmangled names. Without it functions are exported from C++ DLLs with their names mangled. I.e. It adds numbers and non-alphanumeric characters. You may name the .DEF file anything you want so long as it has an "EXPORTS" header and the .DEF extension.

I am tring the following

"C:\Program Files\Microsoft Visual Studio\VB98\VB6.EXE" /make "C:\Users\myuser\Desktop\manager\Project1.vbp" /D DEF="C:\Users\myuser\Desktop\manager\Config.DEF"

But still does not work.

What am I doing wrong?

Any help would be GREATE!

A DEF file is used by the VS C++ compiler not the VB6 compiler.

Thanks at all.

I just ran across this VERY excellent code that WILL allow you to create a STANDARD .DLL using VB6!

I followed the step-by-step instructions (created VB6 Add-In), and copied files to make a "Standard DLL" project template.

Works perfectly (and it's FREE)!
