DLL: Exporting Functions

[Guest]

Hello,

I have a dll which I compiled in VB. Now I would like to use this dll in
MapBasic program. However, I keep getting an error saying that the function
which I am calling cannong be found. After doing some research, I learned
that VB's functions are not exportable and suggestion is to get PowerBasic or
XBasic.

I am just starting with VB so I am not sure if I am right, but can somebody
please tell me if I can make exportable functions in VB6? Or, is there a
'free' compiler that would make a proper DLL in VB? Does the newest VB.NET
version make a proper DLL? Thank you .

Victor.

VB.NET makes Control Library DLL's & Class Library DLL's, but if you want a
non-MFC DLL then you need to write it in C/C++

There is an example of exporting functions & using them in VB.NET, here:

VB.NET doesn't support exporting functions, and VB6 doesn't support that
too. However, it's possible to intercept the linking process of VB6 and
make it create a DLL that exports functions. A German article about this
technique can be found here:

I don't know of any free compilers, but Delphi and VC++ can be used to
create such DLLs.

Does the newest VB.NET version make a proper DLL?

No, VB.NET cannot be used to create native DLLs.

I am not aware of an English article about this topic, but maybe an
automatic translation to English is sufficient:

Hi,

Very sorry to bother you again. I am having difficulty figuring out what
this application is doing. I've downloaded the application but not sure what
I should enter in "Linker-Controller" section. Sorry, I am quite new to VB
could you please clarify on what this app is doing? Thank you so much for
all your help.

Thank you,
Victor.
