There is an easier way to see the compiled code than this by using VC++ 6.0.
Here are step by step instructions:

- Create a new VB project, and write a sample code in Form_Click in Form1.
- Add a MsgBox "Hello" in the code.
- Save the project(a must).
- Go to Project|Properties|Compile, and select "Create Symbolic Debug Info".
- Compile and save.
- Run the EXE from Windows Explorer.
- Go to VC++ 6.0|File|Close Workspace.
- Go to Build|Start Debug|Attach to process, and select your running EXE.
- Click on Form1, this will execute Form_Click, and a message box with the
word Hello will appear. Do not click OK yet.
- Go to VC++ 6.0|Debug|Break.
- Go to View|Debug Windows, and make sure that "Call Stack" window is
visible.
- One of the lines in "Call Stack" shows "Form1::Form_Click()", double click
on that, this will view the source code.
- Now Right Click on any source line that you like, and select "Go to
Disassembly", this will show the source and what VB compiled the code to in
an easy to view format.
- After you are done, make sure that you turn off the debug info in your VB6
project and recompile, otherwise, you will make it easier for a hacker to
break your code.

It's important to note that VB6 does source level optimization, a specific
line may be compiled differently based on the lines before it.

Please start a new thread if you want to discuss this further as this might
be off topic...
