Question DLL import question?

[casper]

Hi there,

does anyone know the differences of the following dll import?

1. Using "Public Declare Sub TEST Lib "TEST.dll ()
2. Using "<DllImport("KERNEL32.DLL"
3. By Adding the dll file to the COM component

what does tlb (type library) file? how does it different with dll file?

thanks

1 and 2 are for importing functions that are exported from non-COM DLLs, while 3 is obviously only valid for COM components.

1 is the old VB6 way of importing external functions while 2 is the .NET way. Both work in VB.NET but I'd suggest you use 2. There are a few things that you can do with DllImport that you can't with Declare.

Look first, ask questions later:
