    Obtaining Functions from a .DLL?? (VB6)

    OK, another silly question from the newbie. I have no idea if this is possible in VB, but I have seen it done in C++.

    On your computer is a file named "pstorec.dll". In this library are several "functions" (and "methods"??) that can be called -- stuff like "Create Type", "Create SubType", "Delete Type", "Get SubType Info", "Enum Types", etc. These allow a user to access and manipulate the Protected Storage System Provider data.

    In C++, one can Load the DLL {LoadLibrary("pstorec.dll")}, call a function, and manipulate the Pstores data.

    Can VB6 do the same type of thing??? How? Thanks.

    Well, based on experience with VBA, sure, why not? When you use a Declare statement to educate the VB/VBA environment about the parameters for an external function, you will have to use variable types that are legal in VB. This can be rather impenetrable without a lot of guidance. However, once you have it down, you can simply invoke the function and the VB runtime or VBA host will attend to the loading of the DLL into memory.

    Now... hopefully you will get some pointers about where you can crib those Declare statements.

    An alternative to try would be to set a reference to it in your VB project: Project > References, and scroll though the displayed list to see if the .dll is there (if it's registered on the machine, then it should appear in the list). Put a checkmark to set the reference, and you should then have access to the functions in the .dll - at that point you should be able to examine them in the Object Brower (F2, then select the appropriate library in the libraries dropdown).
