] | I'm working on the creation of an ActiveX EXE using VB6, and the only example I got is all written in Delphi.
Reading the example code, I noticed there are some functions whose signatures are followed by the **safecall** keyword. Here's an example:
```
function AddSymbol(ASymbol: OleVariant): WordBool; safecall;
```... | Safecall passes parameters from right to left, instead of the pascal or register (default) from left to right
With safecall, the procedure or function removes parameters from the stack upon returning (like pascal, but not like cdecl where it's up to the caller)
