Are there any of you super brainy folks out there who would be willing to write a step by step tutorial for creating a plugin DLL in VB6? I know I would greatly appreciate it. Frankly, I've read everything I could find on the subject both here and on any other resource I could find, but I'm still hazy on it!

If you could write a simple DLL that had say two simple bits of functionality... Say a routine that takes a string as a parameter and throws up a MsgBox displaying that string, then returns the button clicked as a result (i.e. VBOk or VBCancel for example). The second one could take a numerical parameter and returned its string equivalent. If I could see, step for step what it took to get that simple functionality into a plugin it would greatly help me to wrap my head around the process.

Any soul kind enough to do that service for the community (as I'm sure I'm not the only one who'd see the utility of it) should be put in for sainthood!

I didnt think you could make one in visual basic 6.. although you -can- make them in visual basic.net..

Atleast that's what i thought.

theres a sticky devoted to the topic in this very forum

vbAdvance is quite neat, but there are a few other ways as well

As I said If someone would be kind enough to go through a step-by-step, that'd be most helpful...

Did you look in that thread and read thru it? If your using VB6 to make a dll you have 2 options: Writing a c++ wrapper for the dll, or using a third party exporter such as vbAdvance. In that thread there is a link to a code tutorial I wrote for vbAdvance and how to get it setup properly to export vb6 ax dll's as standard dll's - I am assuming you already know how to code in vb6 and write a standard vb6 dll. The rest is just Init and wrapper code for vbAdvance. Have a look-see in that thread, as I said.

If you mean this thread (http://forum.thegamecreators.com/?m=forum_view&t=42070&b=18) Yes I read it... I keep reading about everyone having problems with their "string tables". Is that not an issue with this method? Secondly, when you create the .DLL you outline in that thread, can the resultant .DLL be placed in the Plugins folder and your "Greet" function be accessed in DBPro code by simply:

x$=Greet("abc")

no, its a dll, not a plugin - therefore this method has no string table issue I don't know from string table mumbo-jumbo and dont code in any form of c. If you do vb.net you can make a dll and use zk's converter to make it a dll. He was also working on the converter generating the string table automatically for it to be a plugin for dbp. Don't know what the current status is with that.

You see, that's what I was talking about though... If you read the original message it was refering to making a "plugin DLL" in VB6 and not an API DLL. Obviously being able to make an API DLL is the precursor to making a plugin DLL, but it is not the end product.

If you want to make a plugin, go do it in C++.

If you want to write an external DLL, I recommend you use vbAdvance.

(I think vbAdvance DLLs just don't work with DBC very well...)
