Are there specific security precautions (input validations for example) that are documented somewhere to prevent hackers from compromising a credit card ASP application? In particular, can we prevent a buffer overflow by using the LEFT function to grab only the necessary characters from the credit card text field?
View RepliesI'm trying to retreive and display a list of showrooms in the United States. The user is presented with a map of the US and an image map has the co-ordinates. The user clicks on a state and "Viola!", all in that state are listed.
It works great, except for two states; California and Florida. On those, I get the following error:

Response object error 'ASP 0251 : 80004005'
Response Buffer Limit Exceeded
/default.asp, line 0
Execution of the ASP page caused the Response Buffer to exceed its configured limit.
There isn't that much data being pulled from the database; only 77 records for Florida, only 122 for California. There aren't that many fields in any of the recordsets, either, and none of them are more than 500 characters in length (all varchar with some int dbtypes.) Code:
Is it possible to set buffer size of ASP output?
View Replies View RelatedIs it possible to "intercept" all calls to conn.execute and have them go to
a checking routine that will either let the command go through or terminate
it if it contains some illegal instructions? My clients company has had its
hacker free status revoked due to the possibility of sql injection. I could
put a function before every single conn.execute but we have hundreds of
them. Just wondering if there is some way of telling it to do something else
first. Maybe I can redefine conn.execute somehow?
I am using the method below to make sure that the query isNumeric and not longer than 4. It's a little snippet I found in another post... It works fine but I'm questioning whether it's enough.
URls like this, itemdetail.asp?-=#&ItemID=906, don't throw any errors because the "ItemID=906" is fine. Does the method used below really protect against SQL Injections in this case?
Code: ....
I have been given a site to redo. In the process of looking at the code, the live site is open to SQL injection. I know what needs to be done but limited time right now to redo correctly. In the interm while I am rewriting the site, will adding a few lines of code as below prevent SQL injection until I have the time to rebuild the functions and move to stored procedures.
Basically client side I added a onKeypress javascript routine to look for ' or " and disallow in login fields ....
What causes this error when trying to submit data into a database with asp? Code:
Your request was submitted Error Occurred: Overflow
I am getting this error.
Microsoft VBScript runtime (0x800A0006)
Overflow: '[number: 32768]'
I am using if and case statments a lot, at certain point when I am just
putting another case statment its giving me this error. if I am removing
that line its OK
same code I tried with if conditions and clng(objRec("TEMP_TYPE"))
Here is my code:
Ok, so on certain computers in my office I get this dialog box that comes up when I start internet explorer, that has this error in it: Stack overflow at line: 846.
All I do though is click "OK" and it proceeds as normal. I have my homepage set to my company web site. But this error only seems to happen on 3 of the computers, they are all running Windows 2000. The 3 it doesn't show up on are running win XP pro. Anyone know what this is and what I should do to fix it?
we use an E-office application where server is SQL server 7.0 and client side
its MS access
In our VB program we use ASP to synchronization and update client
database from server and each table is updated afresh . This program was
running fine and
all tables were being Updated until number of records in 1 table went
above 3000 . Now this table gives overflow error while others are being
updated correctly .
the error is 'Error in Function MaterialMasterUpdate: Overflow'
We use filestream object for this communication , is there some
limit to it
I got the following error: Arithmetic overflow error converting numeric to data type numeric I'm sure it was one of my currency fields. However, the real total of that

How did it get submitted as $776.9200000000001 ?
Is there a way I can assure those extra digits get whacked?
I have several websites running on a 2003 IIS6 box, all
running basically the same code (each site has its own home directory
and copy of the code). All are running in the same App Pool.
One site gives the 800a0006 error on a formatpercent, another site (on
the same server) does not.
Here's the kicker...the one site only fails if the number is LESS THAN
1.
formatpercent(0.999) ---overflow
formatpercent(1.000) ---100%
The one "abnormality" is that the default script language is set to
jscript, and I call the function via a call to a vbscript block -- but
this works on several other sites on this same server.
I'm getting the Stack Overflow error on the request.form from a large TEXTAREA submission. Actually, the problem is _I'm_ not getting it, only my client is, and
we're testing the exact same content in the post.
First, is there a simple way around this error other than running the long function found here http://www.pstruh.cz/tips/detpg_largepost.htm. This form I'm using has only ONE form field, and the data is being written directly to a text file to avoid SQL datalength limits (or so I thought).
Secondly, why would I be able to submit that data successfully, but my client wouldn't? My client machine is XP Pro. Would they struggle if they were using W2k or W98?
I have an ASP script that show a big number of record (about 1100 rows) so I have set the Response.buffer value to off.
With Firefox all works fine, the script shows the record one by one while it loads them. The problem is that using Internet Explorer I can see the records only once that all rows are loaded.
Is there any way to reach the content of the DBMS_OUTPUT buffer after
calling an Oracle stored procedure from ASP/ADO
Set objFSO = Server.CreateObject("Scripting.FileSystemObject")
Set objTemplateFile = objFSO.OpenTextFile(Server.MapPath("template.txt"))
strTemplateText = objTemplateFile.ReadAll
objTemplateFile.Close
Set objTemplateFile = Nothing
strTextToPrint = strTemplateText
strTextToPrint = Replace(strTextToPrint, "{date}", Date())
strTextToPrint = Replace(strTextToPrint, "{time}", Time())
strTextToPrint = Replace(strTextToPrint, "{message}", strMessage)
Response.Write strtexttoprint
How do I send strTextToPrint to my default printer?
I'm experiencing bad performance migrating from IIS 5 to IIS 6 on a server with identical Hardware configuration on some ASP pages.I notice that setting
response.buffer = true
Does exist a way to read the buffered output as does the php function ob_get_contents() ?
Actually this can read the dynamic output of an include.
how to create a download buffer? I'll explain a little bit. What I mean by a download buffer is a script that will count how many people are downloading a certain file, then after say 50 or so are downloading that file, it will make everyone else who wants to download it have to wait a certain amount of time(ex. 5 minutes).
I got the idea from Fileplanet.com and Fileshack.com. Seems like a pretty cool system and it appears to be written in asp.net on their sites.
I have over 6000 record in a SQL Server database (in one table) and trying to fetch all these records at once but it always fails. I have tried every thing, increased Script time out function to 300 even to 3000 but still same. Used response.buffer=false too but no change.
View Replies View RelatedWhen you use response.buffer=true , I realize that anything writeen with response.write will not be outputted until you do response.flush, correct?
With that said, what about this (I don't know if it's the same as response.write or not)
<% if page = 1 then %>
(Load pictures 1-20) by using html (not response.write)
<% end if %>
<% if page = 2 then %>
(Load pictures 21-40) by using html (not response.write)
<% end if %>
I notice a lag in the page (it stays blank for a second or so before any of the page loads) and I wondered if changing buffer type to true and adding a response.flush between every 5 or so pictures would make that better.
i am getting this error when doing a select and do while not rs.eof

response.write (rs("postcode") &" "& rs("road_name") &" "& rs("house_number") &" "& rs("phone_number"))

I know some of the gurus round here use Firefox a lot. I'm experiencing problems with using:
Code:
<% Response.Buffer = True
...
Response.Flush %>
It never seems to flush the buffer. Does anybody have any ASP script with buffer flushing involved? Do they work for you on Firefox?
How can I set the amount of Response.buffer? How can I block scripting if the buffer gets more than 2mb?
View Replies View RelatedIn the following code when i = 500 the buffer on the server is flushed
to the client. However, because the content that is sent to the browser
contains an html table Internet Explorer does not display the table
until it receives the closing </table> tag.
The question is, am I
correct in saying that the buffer on the server is CLEARED when i =
500? It will be empty for a split second until the loop resumes again.
Am I correct? Code:
I was thinking of using something like:
For...
IF x MOD 20 = 0 AND Response.IsClientConnected=false THEN
EXIT FOR
END IF
some code here
Next
so the FOR...NEXT statement would stop if a client leaves the page or hits the stop button.
But is it pointless when using it with <% Response.Buffer = True %> since it processes the entire page before displaying it to the user.
If response.buffer is set to true, and no response.flush has been executed, is it accurate to expect that my browser should not be rendering the content which I (well Ok, someone else) is sending in response.write statements?

View Replies View RelatedWhen I try to print a large table I get "Response Buffer Limit Exceeded". When the table is small, this is not a problem. I am sure that there is no infinite loop, and have tried setting the buffer to false, in addition to occassionally trying to flush the buffer. I can not modify the server settings. What can else can I try? I'd rather not split up my table into multiple pages.
