ASP and DLLs

[deepatpaul]

I have a project coming up that will (eventually) require my ASP (3.0) scripts to make calls to custom DLLs. For the time being we need to create the necessary "hooks" so in the future the DLLs can just read these hooks and get the necessary data with little stress.

My questions:
1. What source language can you create DLLs in?
2. What, if any, software package is needed to compile DLLs?
3. How would I be able to have ASP code be read into a DLL?
4. Can DLLs be created to call external database servers to store data?

1) dll's are usually created using visual basic
2) you'll need some flavor of visual basic to compile them
3)Usually you do something like set myvariable = server.createobject("dllname.classname") then refer to thisothervariable=myvariable.myfunctioninsidetheclass(myparameters)
4)yes, using much the same methods as vbscript.

This is quite a bit different from vbscript, so you'll need to do a bit of research before trying to write and compile your first dll.

You may already be familiar with using DLLs from ASP ... have you ever used ADO recordsets or the FileSystemObject?

I'm mildly familiar with using ADO and FSO. They both call DLLs?

One usually uses ADO and FSO without also using .dll files but of course one could use both if desired.

The both ARE DLLs.

msado15.dll and scrrun.dll
