please give some sample code... thanks...

I think you might want to read some VB and C++ books...
Well, you would want to try something like this:
In this order:
--In c++, use the * pointers to get the memory address of the 'give' variable
--Save the memory address into a .txt file
----(Note: ) the memory address may change every time you run the program, so you would need to re-save the memory address again each time you run the program
----(Note: ) aka, just don't get the memory address and assume that it will be constant. Because it won't. Just add a line of code that gets & saves it each time.
--In the VB program, open up that text file so you can read the memory address
--Save the information at that memory address (which is the memory address of the 'give' variable) into a new variable in the VB program.
This should solve your problem in the simplest way possible.
I will not give you code samples, because it is quite simple to do this with both VB and C++. I know both of them rather well, and I can tell you that it is very easy. If you really don't get it, use Google to look up something like "how to read a .txt file in VB" or something. I taught myself both languages almost entirely in this way.
