Hi,
You are probably right but I don't know which type of variable I can use.
I'm asking me something else also : the dll I'm using is a dll which was
created by embedded Visual C++ 3.0 and I want to use it on a Pocket PC 2003
device....
I know that eVC++3.0 is compatible with Pocket PC 2002 but I don't know if
it's compatible with Pocket PC 2003.
