Exception Handling
I have a piece of code which causes an exception. Now i don't know why that is. I would like to know the best way to debug the exception.
I know about try and catch statements. However with these you need to have a basic idea of the type of exceptions that could occur. Does someone have a better suggestion on how to debug an exception?
Exception Handling
I am using global.asax to handle my web application exceptions and have
configured it to create event log entries for errors that occur and to
display an error page advising the user to contact the helpdesk.
I have an intermittent uninitialised object error that I am not able to
reproduce in test and for which I really need the source line number.
I believe this information is contained in the PDB but am not sure if one is
created if I set the debug="true" flag in the compilation part of the
system.web section of the web.config when the application is recompiled.
Authorization Exception
I am trying to read an XML file as below,
DS.ReadXml("http://localhost/PM/" & Me.ViewXML & ".XML", XmlReadMode.InferSchema)
Using Windows Authorization I get the exception below:
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Net.WebException: The remote server returned an error: (401) Unauthorized.
Invalid_viewstate Exception
I have a system that tries to find holes in my web site. One of the things
it has found and has been sent to me is,
an Invalid_Viewstate exception. I will provide the stack trace below. If
you read down the stack trace it talks about "Invalid chararcter in a base-64
string" error. After reading much about this have not found any resolution.
I did read where one person said that people hit sites that require
information and they sending bad or spam in hopes the site will forward the
information on to an email and my site is capturing that because they also
are changing the hidden field _VIEWSTATE which in turn causes this exception.
I also read that the data that is being entered is not passing validation
and there is a need to trap for it. Code:
CreateObject Exception
we use an ASP page to upload files but sometimes it doesnot work as it suppose to do and we found error log in Application Error as:
Event Type: Error
Event Source: Active Server Pages
Event Category: None
Event ID: 5
Date: 11/27/2006
Time: 9:17:08 AM
Description:
Error: File /ASP/UploadFile.asp CreateObject Exception. The CreateObject of
'(null)' caused exception C0000005..
This exception happened sporadically. I didnot find a way to reproduce the error.
Exception Error
I am getting ready to give a whole application to a customer for website integration. I am finishing it up now by doing a final system check. When i ran the following script if gave me the following error:
error '80020009'
Exception occurred. /pabstproductions/WebDesign/VortexRegSys/ASP/YouthUpdate.asp, line 78
I really could use some help figuring this out Code:
Exception Occurred
I am trying to do a real simple bit of code here but i cant see where i am going wrong. I am trying to pull some titles out of the database and when i have 5 i want it to stop.
Well it is giving me an Exception Occured error. I have checked that the query is valid SQL, and i have also restructured my Do While Loop so to test the data is being pulled from the db and it is fine.
Could some one please have a look at this for me as i don't really understand what is happening. The commented out part at the bottom is the code that i used to test that something could be extracted from the Database. Code:
Exception '80020009'
When i try to execute this cycle:
<%while not (oRS("IDFoto")=IDFoto)
IDPrec=oRS("IDFoto")
oRS.MoveNext
wend%>
i get the error:
80020009 Exception Occurred
I want to select the record with the field IDFOTO= the value in the variable
IDFoto I'm sure the cycle doesn't work, if i modify it so:
while (oRS("IDFoto")=IDFoto)
it works (but with no right result of course).
401 Unauthorized Exception
I am trying to convert a word document to pdf file from java for this, I am using a asp file to convert doc file to pdf. I got it working when I put the url which has file name as the query string in the browser but when I call that asp file through the java application I am getting 401 unauthorized xxx exception.
I am using weblogic 7 as the app server and IIS as the web server and Adobe acrobat 6 which has pdf distiller in it. The problem is when the asp file tries to create the Server.createObject(pdfdistiller.pdfdistiller.1), since it is a third party component, the machine doesnt allow me to create the object, I guess I am not sure, but I got it working when I put the virtual folder security anonymous user as domain admin but if i give any other user name it is giving the exception 401 unauthorized exception.
80020009 Exception Occurred
I'm getting an '80020009 exception occurred' error for some reason, even though I know that there is a corresponding record in the database. This happens on some records but not most. Any ideas? Code:
View Replies View RelatedException Occured Only On One Record
I'm getting an "exception occured" error pointing to this line :
<%=Replace(Replace(rs1("racelength"),"D","")," ","")
%>
..when all the other records (84 that i'm displaying) have the same
display reference, and they are all fine. The data in the dbase is not
different than the other data corresponding to this field
??
Script Engine Exception?
The periodic error below keeps coming up and causing our server to crash. Once it happens, the only way to recover is to issue an IISRESET or reboot. We've updating the scripting engine, and database engine. The ASP code is connecting to an Access database. Is there anything that can be done about this? It happens several times a week. Code:

I have an ASP page that returns all the items in a database where a certain field (called Period) is equal to a given number. This number is pass in the URL from a link on the previous page. The script works fine but some of the periods contain lots of items (up to about 600), and the page takes an age to load, so I decided to use paging.
I found what looked to be a great peice of code on asp101 which I have adapted, but I am having problems. The code works fine for all of the pages except the last one, where upon it generates:
Error Type:
(0x80020009)
Exception occurred.
/sleaMusTrust/DBTemp/ArtefactsP.asp, line 14
This line to me seems to have no problem at all (code listing is below). The particular block of code is generating links to jump to different pages, and I need this to include the same period, so I simply add it to the end of the url. However, if I delete the added period from the URL the page works (and carries on working if I type the URL manually into the browser address box). Code:
Exception Occurred.(0x80020009)
In the SQL select statement I need to compare with another field. This, another, field is sitting in the stored procedure. I have to call to the stored procedure to get this field…So I can do the comparison.
Here is what I tried: ....
Script Engine Exception?
The error log entry below has occured a few times this month. Each time, IIS
stops serving pages until IISRESET. Does anyone know what the problem might
be? Code:
Exception When Accessing Dictionary Object
I have a server running Windows Server 2003, on which two of the web
sites use the MegaBBS ASP forum software. Both sites suddenly developed
the same error, which seems to be connected to the dictionary object.
ASP... Code:
Exception Occurred /deleteTitle.asp, Line 38
I have a table inside access DB built like a tree, every record(=node) is a "title" that has a 'name' and 'paret' fields (and some other fields that are not relevant). I'm simpley trying to print out all the tree's records but I keep getting only a path from the root record to the first leaf.
I have a recursive sub called 'deleteTitles' that needs to perform this task. The var 'currentTitle' is the root node.
On every iteration of the sub I print one son of the current node 'T'. I'll be glad to give more information... Code:
Exception Occurred /deleteTitle.asp, Line 38
I'm trying to delete a tree in my DB using a recursive function. The tree nodes are "T" (titles) The tree root is currentT, on the first call to the function. I get the error above.
View Replies View RelatedSql Open Exception Persists Until I Restart IIS
using win 2000, asp and mysql. when i perform a bad sql statement in asp like...
dim cn
set cn = server.CreateObject("adodb.connection")
cn.Open "DRIVER={MySQL ODBC 3.51 Driver};SERVER=localhost;DATABASE=homerton;UID=root;PWD=;OPTION=35"
dim rs
set rs = server.CreateObject("adodb.recordset")
sql = "selec * from tablename" 'note the typo on select
rs.Open sql,cn
IIS complains with
Microsoft VBScript runtime (0x800A01FB)
An exception occurred: 'Open'
If i correct the error IIS still fails to work until i restart the w3svc service. On another pc running the same setup this doesn't happen, and correcting the typo enables the asp to work again.
IIS isn't crashing, it would still run a simple asp page with response.write etc on my pc, it's just when it comes to an sql statement again.
Anyone know why this occurs and if there's a solution?
Exception Occurred Strange Error
Im writing a script that has a lot of "nested" IF statements - it breaks a complicated situation down through a sort of logic system, and when it reaches the end of the tree it performs a certain task - in this case, it writes a row of data into a table.
Its very annoying that the IF statements work exactly as I want/expect them to...but when it gets to the end of the tree of IF's I get the following error: Code:
Error: Script Engine Exception.
Has anyone run into this situation and could possibly help me out? I am running on w2k vf mssql
Description:
Error: Script Engine Exception. A ScriptEngine threw expectio
'C0000005' in 'IActiveScript::SetScriptState()' fro

Type Mismatch & Exception Occured
We have an web application called I-CAL(Interactive Personal Loan Calculator). This application is configured on server with Win 2000, IIS 5.0 and with 1 GB Ram.
The application is facing a very rare problem which is difficult to reproduce and trace. The problem statement is as follows:
The application faces an ASP Error called "Type Mismatch" and the line it points the error to is the statement where we create an Object of the Business Component. For Eg: Set Obj = Server.CreateObject("PrgABC.clsXyz").
This is a very rare error which does'nt occur consistently. We are not able to trace it also. Code:
Error Type: (0x80020009) Exception Occurred.
I get the following error from the code below:
Error Type: (0x80020009)
Exception occurred.
/diary.asp, line 53
The specific part that causes the exception is when I try to access
rsAppsTemp("AppointmentDate") in the While loop. For some reason it works
fine in the If statement above it, but not in the While loop.
Any ideas?

ASP Handling
I have been trying to find a script on the net that would allow me to handle directory listings through ASP. I'm basically looking to change the default generated pages when browsing directories. Eventually I would love to be able to change which directories/files show based on permissions and be able to allow uploads to current directory listings.

Error Handling Using Asp
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???

Error Handling In ASP
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.
String Handling
if I have two strings as follows :
"1,3,45,65,777,89,00
and
"8,9,67,54,89,23
The numbers represent a predefined access permission to a certain file.
I need a function to sift through the first string, and compare it to the second string. What numbers are located in the second string, which are are located in the first string need to be removed (from the second string) leaving only unmatched numbers beind.
