Detect Whats In A String After A Character
i have a browse button on a web form that the user can upload images via ftp. the user clicks on the browse button to browse a file on his computer and the text field displays the path - "mycomputerdesktopmyimage.jpg".
i need to get the name of the image and insert the name into my database. so i need to be able to search the string ("mycomputerdesktopmyimage.jpg") and insert all the characters after the last "" which will give me the image name. ive tried just writing out the string in asp (jscript), but it gives me "mycomputerdesktopmyimage.jpg" without all the backslashes.
how do i get those backslashes back into the string? my second question is how do i search for the characters after the last backslash? i know i can use a substring on this, but how can i use it for the last backslash?

What is the best way to check each character within a string?
For doing something like encryption, where you check character 1 and replace
it with a different character.. then check character 2 and replace it with a
different character.... etc.... until completing the string?

I have a page that will display a list of locations from an SQL DB. Users need to be able to sort and/or search these locations by industry
Each location has a 4 character desgnation, the 3rd character of which indicates industry. How do I query the DB in an ASP page to recognize ONLY the third character in the string?

I'm passing a unique identifier from page1 to page2 to page3 querried from MS SQL Server. When I pass the value, it puts the value in the curly brackets. (Page1 is for display and Page2 is for edit and Page3 is update edit)
When I go to Page3, it gives me an error saying "Syntax error converting from a character string to uniqueidentifier" {7171B9BD-4599-43D9-9521-3DA583A1BB1A} This is the value and the error page says "id=%7B7171B9BD-4599-43D9-9521-3DA583A1BB1A%7D" It seems tp put "%7B" and "%7D" for "{" and "}". Has anyone seen this?
I'm also passing numbers and text and they don't seem to have this problem, just the unique key.

I'm using Msxml2.ServerXMLHTTP.3.0 to fetch a HTML page on a remote
server. The fetched page is then parsed and the information of interest
is extracted and send to the client browser.
However, the remote server does not specify any character coding in its
headers. If using ResponseText property in ServerXMLHTTP, some
international characters are not decoded correctly. This is due to
ResponseText assuming UTF-8 coding if no character set is specified.
My solution is to use the ResponseBody property which returns the web
page as an array of unsigned bytes. I then convert the data to a string
using the ADODB.Stream method as described here:
http://www.motobit.com/tips/detpg_binarytostring/
The string is then parsed and the required information is pulled out.
This solution works just fine but I wonder if there is some more
efficient (without the need for a byte to string converion) way to
solve the problem.

A few weeks ago I was told in this forum that ASP would be a great solution to a large web site. I purchased a book about ASP.Net but have also seen info on ASP. Can you please tell me what is the difference between the two?
I don't know computer programming at all. Dreamweaver MX is the program I use. Can ASP be done with a WYSIWYG program? I have set up databases in Access & built web sites with DW MX I am not sure how to tie the two together.

How can I make such a bold statement? Two words: Buffer Overflow.
In the very first class I took in programming (those many years ago), we were berated class after class about proper bounds checking to prevent buffer overflows. What this means in simple terms is that every time my program asked the user for input, it had better check to make sure the input fit in the place I reserved for it. If I asked for a ''Y/N'' and I got a ''yes'' or a ''no'', those extra characters had to go somewhere and I had better be prepared for them.

It sounds like you are looking at the properties of the WebSites main branch, when you need to look to the first element under this branch (opening it) to the next "step down", and check the properties of the child element (mine is called "default web site", but yours perhaps has been changed from that).
It also contains an "advanced" button on the Web Site tab (right next to the "IP Address" field) which allows "multiple" identities, which is the part which I couldn't to work with 100% consistency.

I've done several sites with ASP that use an Access database, and it has worked fine so far. I will be developing a much larger site and I need to know if Access just isn't going to cut it anymore.
Is MSSQL what I should use instead? How much is too much for an Access database? What are the differences in coding for something besides Access? (is it just in the connection string, or what?)

anyone has any idea what IMS Package is all about? i read that The IMS Package consists of two major elements: a special XML file describing the content organization and resources in a Package, and the physical files being described by the XML.
The special XML file is named as imsmanifest.XML, together with all resources, when import, will be extracted from a single .zip file.
Does any one know where i can get such kind of .zip files so that i can check what exactly happening inside?

I am using a stored procedure that outputs multiple recordsets.
I use <% SET rsDisplay = rsDisplay.NextRecordset() %to step to the
next recordset.
In one particular condition the final recordset is not passed to the
page, so I need to detect that the object is empty.
I did just try <% If NOT rsDisplay.EOF Then %but I get:
Microsoft VBScript runtime error '800a01a8'
Object required
Any ideas how I can trap this error? I just want the area on the ASP
page not to display when there isn't a final recordset.

What I need is a field that is a drop down and when selected if less than four it needs to show a new field to select.
Once the total of the drop downs adds up to 4 or above then no more are created. This would be in the middle of a bigger form. Code:

I'm working on an app to upload pictures to my Web page.
As part of it, I need to know the dimensions of the
images - how many pixels wide by how many pixels high. Is
there any way, as part of the upload or immediately after,
that I can detect that?
Also, though the solution isn't exactly appropriate to
this NG, I would also accept a client-side solution to
this problem.

Normally I would do something like
if request.form("submitbutton.x") <"" then
....
end if
But I found a problem when the browser uses the 'alt text' instead of
the image (when the image is not found, or if the browser is not
displaying graphics, etc. How do you detect that? or should I?

I am working with a bunch of old code so I can really restructure the includes, otherwise I guess I could change all the #include statements to #include-once. Anyway, If I have a file with a class like this:
Class myClass
end class
I get a "name redefined" error. I've been seeing these and indeed from goolge searches, it's because the file is somehow included more than once. This problem doesn't occur for functions and the old code bases just used functions whereas I would like to add some classes. In C you used to be able to detect that at the top of the file and not included the rest of the file if it is allready included. I just want to at least detect it so I don't redeclare the class.
