Type Mismatch Error = 13
 

I am running an intranet with both ASP and .exe components. I get this error when I am trying to save some records. The error persists even when i change the type of the parameter being passed to the Sub. The major problem is that I cannot trace from which SQL statement the error is arising. If anyone can help me in this i will really appreciate it because it is part of a live system and mission-critical. Even if u dont solve the problem at least if u can give me any information as to when this error occurs when applying SQL statements and how it may be resolved i'll be only too glad. You can also eMail me when u reply so that I am aware soonest. Thanx in advance. :)

Right, debugging CGI is notoriously nasty. For starters, if you have option explicit set, turn it off. Secondly, start outputting random text such as "reached this bit" so you know where in the code the error occurs. I think it may be the wierd way in which you treat Rs.Fields("ID").Value as a string in an If statement and yet use the str() function later on which takes a number.

Why would you want to turn of option explicit, that would just cause you program to run slower in general. With it on, it shouldn't give you a type mismatch error, or am I wrong?

Actually, a type mismatch can occur for one of two reasons. Firstly, you're trying to do something impossible that VB can't do, such as set an Object equal to a Long. Secondly, you're trying to do something such as set a string equal to a number, which under strict typecasting (option explicit on) will raise an error. By turning it off, and seeing if the error occurs again, you can decide which of the two circumstances it is and eliminate down to specific areas of the code, which is useful with large projects.
Obviously, you'll correct the error and turn Option Explicit back on for the final compile.

Thanx, that clears up a few things :)

Cool. BTW my favourite run time error has to be "Run-Time Error 17765 The VB Learning Edition does not support this functionality".
