Does GetObject work with ASP?

[Rich]

Hello,

I have not been working with ASP for too long at this time
and am not real familiar with a lot of things about ASP.
I have searched for articles on the following question but
not come up with any definite answers. I would like to
know if it is possible to use GetObject in order to
read/write data between an ASP and an activeX
application. VBS supports GetObject, so I thought ASP
might, but I have not had any luck. Interestingly I can
use CreateObject with ASP but not GetObject. I
experimented with a homemade ActiveX exe I slapped
together with no luck - Can't create ActiveX object
error. I even tried it with an Excel workbook. Also did
not work. Before I assume you can't use GetObject with
ASP I thought I would check if maybe it is a special
syntax I need or GetObject isn't designed for ASP (Note: I
am adding my apps to the ROT to get the GetObject
functionality - which works fine from vbs). Any comments
appreciated.

Thanks,
Rich

Thanks for that suggestion. I think I have played around
a little bit with FileSystemObjec t but was using the wrong
syntax and lost hope. Finally got it to work:

set fso = CreateObject("S cripting.FileSy stemObject")
Set info = fso.CreateTextF ile("ActiveXasp testR.txt")
info.WriteLine "testing"
info.Close

Just needed a little encouragement.

Thanks again,
Rich

Thank you for pointing this out. Actually, I do set fso
to nothing. While I'm at it, may I ask how or if you
could use FileSystemObjec t to write/pass data to an
ActiveX app? (VB6 activeX app). Like in MS Access I could
make a reference to myApp (which would be running and
visible) and do this:

Dim x As New myApp.Class1
x.letSomething = "test"
set x = nothing

where .letSomething is some Public Property Let... in
Class1 and "test" would end up in a textbox on a form of
myApp. Is it possible to use FileSystemObjec t to do
something similar in ASP (or vbs for that matter? For vbs
I added GetObject functionality to my activeX app by
adding it to the Windows Running Object Table and hooking
it, but GetObject not working with ASP this way - which is
what this post is about). If I can do something like this
with FileSystemObjec t, may I ask how this is done? sample
syntax.

Thanks,
Rich

Doesn't ASP release its variables after it's done with the response? I
mean, as long as you release resources (e.g., close open files, recordsets,
connections, etc.), is there something about taking advantage of ASP's
implicit cleanup that is somehow distasteful? Not trying to be
argumentative, just really want to know. Thanks.

There are situations when automatic cleanup cannot occur, especially with
recordsets (and therefore connections as well). It pays to be explicit.

Again, not being argumentative, but can you give me an example of a
situation where letting a variable fall out of scope would have a different
effect than setting it to Nothing? Granted, you've got to close recordsets
and connections, etc., but it seems like you're saying ASP can hold a
reference to an object that from all outward appearances has fallen out of
scope. Is that correct? (The reason I'm so concerned is that I rely on ASP
to release variables all the time, so naturally if it turns out this is bad
I'll have to change my ways.)

It's been a while since I read about this so I don't remember the details
but a recordset object can be in a state where it cannot be closed by going
out of scope (for example, there may be an ongoing or pending Update
operations). This leaves it in memory causing a memory leak which can
eventually crash IIS if it happens enough times.

It has been very well documented in these groups where people have had
problems with IIS crashing every few days, which they have resolved by
modify their code and explicitly closing and destroying their ADO objects.

My simple rule is: If I open it, I close it. If I create it, I destroy it.
