Jamella's Diablo 2 Hero Editor

Full source code and solution & project of Visual Studio 2019

---

When I was a child, I've downloaded JamellaD2E, and I used it to edit my characters and equipments, until now I found the full source code of JD2E, What a coincidence.

---

Note

The source code of JD2E is published by this PDF file: jamella-diablo-ii-source-code.pdf

I've dumped it into cpp source code files, and fixed it for compiling in VS2019.

This is the original read me from the PDF by Jamella:

Source Code of Jamella’s Diablo 2 Editor

2001-03-17

This source code is my intellectual property. It was completely written by myself. I have published it so fellow programmers and other interested people can have a look into the internals of my editor.

If you use parts of the code consider that I needed over half a year to build this program and mention me in your info box if you like.

Other than that your will find some modifications I made after releasing version 3.0 of the editor, so don’t be surprised if you find some extra functions and useless pieces of code.

And please don’t email me and ask me how the code works, because it does and I don’t have time to teach the whole world object-orientated C++. Now dig into it by first reading the header file.

Gathering source code:

1. Use <Google Chrome> to open the PDF File.
2. Ctrl + C/V copy all into <pdf.txt>.
3. Remove the first page(readme part) from txt.
4. Use RegEx to get both <File Name> and <File Content>.
5. Save to source file.

RegEx steps is in this file: index.ts

It is written in TypeScript and run by NodeJS, and no longer need to run now.

Now the source code cannot be compiled yet, because there still has some problem to be solve.

---

Line break problem

First, there is a line break problem in most files, those lines has breaked at wrong position, like in the middle of strings, this problem comes out because PDF file has automatically wrapped at some lines which its width is too long, so I used VS2019 and VSCode to formatted and patched all files to make sure all code files doesn't show any error during just viewing in VS2019 IDE.

---

Gathering resource files

I've got a JamellaD2E v3.0 executable file from tytannial in #1, and I extracted all the missing resource files from the exe, it works perfectly now.

Compile

Warnings

There are a lot of warnings while compiling, because originally this project is written in VC98, so I've disabled these warning belows.

26451;6328;28183;6011;6386;4996;4552;4477;4554;4474;4258;

Loop problem

There is an intresting thing in source code, Jamella write loops like this:

for (int i = 0; i < 100; i++>) {
    // code...
}

// some other code...
int a = i; // he was using variant 'i' without defination, because it has been defined in the loop above.

This habit will cause error in VS2019, so I patched all these codes which show an error while compiling.

CRT Warnings

Because this project is written at VC6 age, the C Runtime has a lot different with now, I need to add _CRT_SECURE_NO_WARNINGS macro to make sure CRT warnings no longer shows.

Macros

JamellaD2E seems has two projects, and you can see it in JamellaD2E.h

• Jamella's Diablo 2 Hero Editor
• Jamella's COM Object

And he use macros to control definitions in source code.

Macro	Project
JAMELLAEDITOR	Jamella's Diablo 2 Hero Editor
JAMELLACOMSERVER	Jamella's COM Object

I've added JAMELLAEDITOR macro for this project.

There are still a lot of macros in JamellaD2E.h, you can check it if you are intresting in it.

Const string problem

Back in VC6's age, you can write code like this without warnings and errors:

char* sz = "Hello, World.";

And now in VS2019, it will show you warnings and errors, you must write like this:

const char* sz = "Hello, World.";

To solve this problem without modifying source code, I changed permissive mode to false for this project.

And also I disabled SDL check.

---

Link

Now, we can compile all files, but missing some static import library files while linking.

• comctl32.lib for using Windows Common Controls.
• Winmm.lib for playing sounds.

I've added it into project configuration.

---

Done

After all these works, we got a executable file of JamellaD2E, this is just what I want, I can build & debug it, and see how it works.

• Written & Open source by Jamella
• Convert to VS2019 solution by zhaoleimxd
• Special thanks to Nedkali for resource files
• Special thanks to tytannial for provide a v3.0 exe to extract resource files
