Use DLL in VB programs

[serhiy]

Goodday everybody...

I would like to know how do i use DLL developed in VC++ in VB programs? What are the procedure i need to do to link it to my VB programs and how do i actually use the functions available in the DLL on my VB programs?

Your help will be most appreciated...

Hi,

It all depends on what sort of dll you created in VC++.

If it is a standard dll, then you access the functions like you do with the win32 API, by declare statements.

If you built an ActiveX dll, then you add a reference to the dll in your project and use it like any other object in VB

thanks for replying Iain17...

i think the DLL that i create is Win32 API because when i was choosing to creat a project in VC++, i chose Win32 Dynamic-Link Library.

"By declare statement"? i don't really understand. i'm quite fresh in these things. so if you don't mind giving a sample or two, i'll be glad...

thanks...

what about ActiveX DLL?
how do i bulid an ActiveX DLL in VC++?
what i know is that u can build a Library-Type DLL...

[Chris]

Serhiy, To build the ActiveX DLL with VC++, you can use the ATL COM AppWizard that come together with VC++.

Try to play around with it.

Cheers!

Chris...

is there any example program or source code that i can referred to?

You might need to register your DLL to use it in VB.
From the DOS prompt run:-
c:\windows\system\regsvr32.exe mydllfile.dll
Then look on the References list in VB and it should be there with an empty checkbox next to it.
Hope that's helped some.

Is there any way I can load Win32 Dll's and Activex Dll at run time?

I think you need to reference it during desing time and not run time.
