How do I read a variable value in another process?

I found this snippet of code which reads the value a variable after first getting its memory address.
Code: Select all
varC=123
Debug varC
ptrA=@varC
Debug ptrA
Debug PeekL(ptrA)
varC=456
Debug PeekL(ptrA)
It works fine. But how can I apply this to another process?
For example if I know the name of a variable in another process to be "VarC" how can I read the value of that variable?
Thanks!

The variable name is useless as it doesn't exist anymore in the compiled application. You need to know the memory addess and use ReadProcessMemory_().

Ah yes, that makes sense.
I'm thinking about the PB debugger. It has the ability to display a variable's value.
If I run my program at the same time I have a different program open in the debugger, how can I find the address of a variable visible in the debugger?

After re-reading my previous post, I can see how it might not be clear what I'm asking.
I'm trying to interact with the PB debugger.
Here's an example:
I have program "A" open in the PB debugger and it's stopped at a "calldebugger" line.
In the debugger I can see a variable in the code of program "A" called "VarC".
Now, I also have another compiled program "B" running separately and I want to see what the value of "VarC" in program "A" is from program "B".
Anyone know how I can do this?

I have no clue but what would be the purpose of this anyway?

The purpose of this would be to be able to display the value of a variable by placing the mouse over it, much like vb.net does.

Why don't you use the Variable or Watchlist function in the Debugger?

Because I'm trying to add this as a feature to my project (PB Project) so I can use it when I program.
I would prefer to have the ability to see the value of a variable by holding my mouse over a variable in the debugger window rather than have to open the debugger scroll through over a hundred variables looking for the one I need.
