Well, your title says "Operation 7 VB".
Operation 7 is the game of course and VB is Visual Basic.
When it comes to Visual Basic I wouldn't be able to help you, but if your looking for C++ then that's a different story.
Follow this:
1. Know Visual Basic well...not just the basics
2. Go here: DirectX and Direct3D
Get and read it, and start coding. If you don't like it that way then follow the step 3.
3. Search up any D3D Operation 7 game source code hacks...no matter if they are old or new.
4. Study them and if you find more than 1 code, try to find the similarities and differences between the two
Hopefully after following these steps you will be able to code your hacks.
SOURCE:
1 year of studying C++
15 months of using C++ theres a difference between the two.
1-2 weeks of studying D3D and DirectX /
