Hi, if I define a structure in VB, what is the most common way to reserve memory for it. Thank you

when do you use api call like globalalloc then? Thanks!

You would only need to use GlobalAlloc if you want your data structure to be available to another application than the one it is declared in...and it is a pain to use from VB!

HTH,

Just declare it. There's a garbage collector in VB and you should be ok. Most VB arrays can be dynamically expanded and reduced and the same is true for strings. The good thing is that it is transparent and you don't need to do the mechanics to allocate new memory just like C++ or other language. Arrays are treated a bit differently and at least you get a fault if you try to access out of the range of it.
