Does anyone know how I can detect if a image is missing from the server before the browser tries to render it, I guess this would have to be done via some sort of preloader, the problem being I am the site in question has around 30,000 images and keeping on top of missing images is a impossiblility.
View RepliesIs there a way I can test if an image file exists before displaying it?
I have a database that has an image field in it that users enter a filename into. Is there a way for me to check using an "if" statement that the file is actually on the drive before displaying it? ie:
<%okimage=(rsFile.Fields.Item("image").Value)
If okimage='actually on the drive' then%>
<img src='(rsFile.Fields.Item("image").Value)'>
<%else%>
<img src='noimage.jpg'>
<%end if%>
I first noticed this in my own app. Images would show up missing [red X] randomly on IE 6.0.2800.1106 on Windows 2000 server.
I then was able to repro this problem on Microsoft's website!!! The page I used was
http://www.microsoft.com/windows/ie...sp1/default.asp
After pressing [F5] to refresh the page six times, I noticed missing images on the page.
This problem seems to be very reproducible. I coded a sample ASP page which references the same images 10 times on the same page. Loaded in IE. Upon pressing [F5] several times, the images will be identified as missing [red X]. Refresh the page again, it's fine.....etc.
I'm up-todate with all latest MS patches. Has anyone else seen this problem?
I read that the "?" caracter can make you trouble with some search spiders. Although I know the Spiders are upgrading to evade this indexing problem, it is still an obstacle for some search engines.How can you refrain from using "?" in urls, for example, in a dinamically runned site?. Some CMS do it replacing that caracter with the slash bar "/", that is more spider-friendly.
In brief:
1. Is "?" still giving problems?
2. In case it's still making problems. How can I replace it?

View Replies View Relatedthat is generated by a database that I don't have access to?
So, I use a database drived store. It is not open source, so I do not have access to adjust the HTML that is generated.
Unfortunately, the code is fairly messy, and contains un-necessary breaks, paragraphs, and other code that I don't want there! A lot of it I've been able to adjust with css, but the biggest thing that bugs me, is that there is a table and a td that are at a set width. It is set at 'width=550'. I would like to either remove that, or change it to 'width=95%'.
Is there anyway I can accomplish this? What I do is create a template .htm page that the asp uses. Is there anything I can do in the .htm to replace or remove this HTML? Javascript? A snippet of ASP code? Or should I just learn to live with it?

I'm sure this isn't difficult, but it's Friday afternoon (!).
I'm trying to use a regular expression to match html tags in a string
and convert them to lower case. It's the RegExp object that I'm
struggling with rather then expression syntax.
So far I have this ('HELP!' denotes where I'm stuck):
private function recoverHTML(sHtml)
dim oRegExp
set oRegExp = new RegExp
oRegExp.IgnoreCase = False
oRegExp.Global = True
oRegExp.Pattern = "<(.*?)>"
sHtml = oRegExp.Replace(sHtml, HELP!)
set oRegExp = nothing
end function
I'm thinking of something like this:
"<" & lcase($1) & ">"
What syntax do I need here?
With hosting for clans, more so then not, the clan tags contain charactures
like + { [ in front of the tag letters.
what I am having a problem with is if it starts with a +, it isn't picking
up the name correctly. If in a sql statement, it looks for a tag that starts
with a +, it won't find it. And sometimes, when it is supposed to move the
tag over in a bracket, it moves it without the +.
for example, +EcK+ is the tag, it will either not find it, or move it over
as EcK without the +'s.
is there any way around this?

i am having trouble getting my REPLACE fn. to replace whole words only. basically, i'm running a 'spelling checker' fn. that uses the REPLACE fn. to find incorrect spellings and replace them. problem is, the fn. seems to replace all instances of a string, and not a whole word only as I intend it to be:

View Replies View RelatedI have a search results page that lists a series of records with clickable links to view the records. When you click on the link to the record, the record id, the search terms used, and the search type (exactphrase or anywords) is sent through the query string.
On the record page I have been trying to find a regular expression that would find and replace the search terms with < strong >< /strong > to highlight them. I am struggling.
Does any use a similar regular expression. One that, if flagged, will replace an exact string (phrase) or loop through an array replacing any of the words in the string?

When i insert into a SQL database a value, say 4.50, through an ASP, it will display in the SQL as 4.5,

We created an asp.net 2.0 app, which sends smtp email using System.Web.mail.
The app is in an IIS 6 application pool isolated to 2.0 apps on a 2003
server.
The app worked fine for a few days; recently however it began failing when
sending to external addresses (it works fine if the recipient is inside our
internal domain).
Comparing the logfiles, I notice when it was working both versions of the
CLR appear in log entries, for example:
(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+C LR+1.1.4322;+.NET+CLR+2.0.50727)
Log entries from when it fails only contain CLR 1.1, for example:
(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1;+.NET+C LR+1.1.4322)
The app is configured to use ASP.NET 2.0. What would be causing that
version to disappear from the log entries (and presumably the app) like
this?
