In case you hadn't noticed I'm trying to make my own sort of class for each control, starting with comboboxes.

Now, what I want to do is to be able to access the class
from any part of code module. But if I make a global variable:


ComboBox cmbOper(WndRect, hWnd, hInst);


It obviously fails miserably because hInst, hWnd and WndRect haven't been created yet.

I tried something to do with the free store, but I couldn't access it outside of the procedure where I created it because the actual memory still existed, but the name I had given it was not declared in the routine I was trying to call it from, and that me... Arrrrgh.

Plain and simple:

How do I create an object that I can access anywhere in my code given that it has its own constructor?

There's got to be a way...

How about a global variable that's a pointer?

ComboBox *gpCombo;

WinMain(...) {
gpCombo = new ComboBox(...);

...

delete gpCombo;
}

Okay...lets see if you can help me with this small query:

Do you know how to use a C++ class from VB???

Hehehe.

PS: This is a genuine question (I just never bothered asking after I only got 2 views, and one was mine)

You'd obviously... err ...

<looks through book>
<realises the 'book' is PLAYBOY>
<sees in-depth article in C++-To-VB class porting on page 27>
<Notices they're 'porting' something else on page 28> ;)
<Can't be bothered to answer question now that he's seen page 31 ;) >
<Sorry, parksie, business before pleasure :D >
