I can't seem to get error handling to work from inside my classes. On the outside it works but on the inside it doesn't. Any thoughts?
if err.number <> 0 then response.write "errors" end if
I'm trying to catch all the errors as I go and I can't do that if it won't work on the inside of my classes.
I'm currently new to OO programming with Classic ASP and have been stopped dead in my tracks on the issue of validation inside classes and if I should be doing things that way. I have been using a User class and it has methods such as Save(), Update() and Delete(). Particularly with the Update() method I'm unsure if I should be validating my form(s) within the class or on the actual edit.asp page that uses the Update() method?
I have two types of edit pages; one for Admin users and one for the My Account page. On the My Account page if the user wants to change their password they have to enter their current password, a new password and then their new password again to confirm .
If an Admin user is updating that same user's info they do not have to go through those steps and they can simple just change the password by typing it in. The point here is that there are two separate cases of validation rules on two separate pages that both use the Update() method. Do you validate your forms inside your classes or outside?
How do i do error handling using asp. Like taking an example i am getting this error on trying to save a record twice whihc has a primary key constraint:
Microsoft OLE DB Provider for ODBC Drivers (0x80040E14)
[Microsoft][ODBC Microsoft Access Driver] The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again.
how can i handle such cases and where do i place the code???
I want to error handling in ASP. But i think that ASP is not enough for
error handling. I have got two chance.
1. I can prapare an error page and control throught IIS.
2. I can use on error resume next.
For 1. This is a general handling. I want to handle local error. Maybe i do
special thing when error occured.
For 2. I have to write alot of lines code. I have to control every line.
Is there a possiblity that, when an error comes in asp page in server, especially with sql script, to hide that error from user and display just Error, report to admin,
i just want to make a general case where when an error comes i should take the page to report to admin.
How i can handle the errors in ASP. Please suggest something.
View Replies View Relatedhow i can handle errors on ASP page. Actually i want to maintain a ErrorLog in Database and want to redirect the user on an Error.asp page where i can show him the error details(i-e error #,Description etc).
I have found "With Endwith" method to handle errors but the problem is that i can only write it with a record set and it will handle only record set related errors and also i have to write With EndWith with each recordSet but i want to handle any error on page at a single place.
what this code doesnt work?

errhand:
response.redirect("error.asp")

View Replies View RelatedI have a usercontrol that consists of a dropdownlist that is databound to a sqldatasource. It gets populated with a staff list.
I've setup properties that can be set for the usercontrol when it's accessed from an aspx page.
I then have an aspx page that has a formview on it that is databound to a sqldatasource.
On the edititemtemplate I bind to the dropdownlist usercontrol's SelectedValue property that I setup.
The bind works, but it seems only works for writing to the control. When I bring up the edit item template, it shows the properly selected value from the dropdownlist, but when I change that value and then hit save, the item I changed to on the usercontrol dropdownlist isn't grabbed and sent back to my server it seems.
On the ORIGINAL version of my page that consists of about 30 other bound controls, it would give me an error of "Cannot insert the value NULL into column 'blahblahblah', table 'Blah.dbo.Blah_tbl'; column does not allow nulls. UPDATE fails.
The statement has been terminated."
But when I rip almost everything out and just leave the company name textbox and the dropdownlist it doesn't return that error, but it still doesn't save my value. It posts back the page as if it had saved it, but no data is updated. Code:
I am am using WDDX.Deserializer.1 to parse some XML data to display on an ASP page. Occasionally, I get an error like this:

Line 25 is:

I would like to set up some error handling so that if this error occurs it will display a custom error message rather than this one. Right now this message occurs near the top of each page on the site, in effect crashing the whole site. How can I test this to see if an error will occur?

View Replies View RelatedIs there an elegant way to check for the REFERENTIAL INTEGRITY VIOLATION in Access via ASP. The reason I ask is that if the user attempts to refresh the screen after implementing an INSERT he will be trying to insert an identical record which thows up the following error (below).
I could place On error resume next before but I find this dangerous or am I overworrying. I could preface the insert by doing a check for the record but this creates longer code which warps my anti-debugging frame of mind :) - is there a better way? Code:

when I try to insert a duplicate record I get the primary key error. which
is good. but I want to generate a user friendly error ... telling the user
that u have got this error because u r trying to insert a duplicate record.
i can simply do so by using "on error resume next"....
this is what I do:
"on error resume next server.transfer("error.asp")"
the problem is it simply takes me to a page where I display an error has
occurred... it doesn't look attractive to display a one line error in a big
page? I hope I am clear....
1. how can I display the error message in my error.asp
2. I can I make it look better... how is error handling done ???
Code:
Error is:
Subscript out of range: '[number: 0]'
or
Subscript out of range: '[number: 1]'
or
Subscript out of range: '[number: 2]'
This is correct in that the variable is empty if user does not fill in correctly. However how do i stop it falling over and just get it to error handle?
e.g. If Subscript out of range: '[number: 2]' empty how do I 'know' this without an error? Code:

I've been searching for some information on the use of Classes in ASP, but

For the majority of my work, I just use plain ASP. On the rare occasion that
I am doing something intensive that does require user interaction I might
create a COM component (ie where performance gain outweighs the overhead of
COM).
A simple Rule-of-Thumb. I imagine this is fairly common practice... (I hope
it is, at least).
However, I'm curious about VBScript Classes. I would have imagined that if a
page was complex enough to merit defining and creating your own
classes/objects, that COM would be appropriate...
In which case, when and how do people use VBScript Classes?
I am re-coding a VB application to be used on the web, some of which requires additional DB components for user registration etc. Usually I use ASP classes to manage the DB I/O stuff but I was wondering whether they are any benefits in having them as VB classes and compiled as dlls?
I like the idea of having the VB application as dlls, but using asp classes for the general functionality of the application. However, I don't wish to do this out of convience for myself.
