Using .NET dll in vb6

[Matt Nunnally]

I created a .NET dll. I want to try to use it with vb6. I did some research on how to do this, but I want to make sure I'm doing it the ideal way so it will work properly.

A bit of background on the DLL. I have one class that I want to expose. All the properties that I want to expose are declared public. That class references a few underlying classes, which are all declared as "Friend" and are marked as ComVisible. I have "Register for COM Interop" marked in the compile flags. I also have "Make Assembly COM-Visible" marked in the assembly information.

I used regasm to register the DLL, which created a .tlb file. In vb6, i tried to reference the .dll but it said cannot add reference. I reference the tlb file and i was able to declare it and use it. I just did a declaration, and did a simple form load which called one of my properties .Name. I know the properties referenced ok because I ran it with no problem. If I changed it to .NAM it failed, which is what I expected. However, none of my properties should up in intellitype. Only the enums.

Is this correct what I am doing? I'm not very familiar with this type of thing. Is there a way for the properties to show in intellitype?

[Matt Nunnally]

Ok. Figured out the intellitype stuff. I had to declare my exposed class as ComClass.

So is this right? Will this work with other languages like FoxPro and C++?

[Matt Nunnally]

I can reference the tlb file now. I can see all of my properties in intellisense. But in runtime, when it tries to create an instance of it, it gets "the system cannot find the file specified"

Is the DLL in the correct place? Maybe it needs to be in (either? both?) the directory with your program, or some globally accessable location like \windows\system 32\ ?
