I have a C program and I am trying to change this program to visual c++

[szypowerr]

This C program about the Execute Assembly Instructions. And I will change this to Visual C++ on form screen. Can anybody help me?

[jumper007]

Could you be more precise ?

[szypowerr]

I did a C program.You can enter to this program assembly instructions and than you can execute this instructions. And now I am trying to this program in visual c++. But I have some problems. if you know C, visual C++ and a little assembly, can you help me? I will show you my program

Post your program here...
