Hey,

I'm having some troubles with memory leaks on my site. I've gone through and checked that I'm closing all database connections and recordsets on each page.

Beyond that, I'm not really sure what to do.

I read in Microsoft help that some functions cause memory leaks, specifically FormatCurrency and Replace, which are used a lot in my site.

Does anyone know of or have alternate functions written to perform these tasks?

Anything else I can look for in regards to memory leaks?

Thanks in advance,

Scott

More specifically look at your codes interactions with DOM objects. Those are the primary sources of memory leaks but maybe this old post may help:

Hi carmichaelscott,

though I'm not using VBScript for server side scripting -

(1) consider to upgrade to VBScript 5.7 (you may be lucky (or not))

(2) Replace() may be replaced by Regexp.Replace() (you pay with a loss of performance;
reusing one RegExp object or creating many of of them may cause new problems)

(3) you can use a .NET StringBuffer to do fancy formatting

(4) you can use other ActiveScript languages (e.g. JScript/Javascript) for critical
functions

Do you have test code (preferably plain command line .vbs) that demonstrates the
memory leaks?

Good luck! (considering your problem, you'll certainly need it)
