Want to check the value of an inputbox against a SQL Server database to prevent a duplicate record being entered.
This is an existing project, and the way they implemented it before was to post to a 2nd ASP page, run the ASP code to check the value, then redirect back to the 1st page if the value was found to be "already used".
There has to be a better way. Is it to use "Postback"?
how can i check if page was initialiy loaded or if it's postback?
View Replies View RelatedI always see the term "postback" from ASP book, but I am not sure if I fully understand the meaning. Here's my understanding so far, please correct me if any mistakes. here's a typical html form:
<form action="process.asp" method="post">
'GUI code
</form>
"postback" action happens when the user click the submit button, that means it will invoke "process.asp" is the above code. In ASP.NET, if the web control has set AutoPostBack property to True, that means when there is any events on the web control, it will invoke "process.asp", just like the user click the submit button.
I am getting to a stage with my site that i have so many entries in the database that i am thinking of adding an a-z at the top of the page. Thinking aboout this further and how it may work i thought that this would use a post back method where it passess for example the letter "a" in the link (Am i on the right lines?

I want to know if the PostBack concept applies to HTML web-based forms, regardless of what programming technologies we use: For example, ASP, ASP.NET, Java, CGI, etc
PostBack means to send the HTML form to the web server Since most of the time I heard this term in ASP.NET circle, thats why I raise this question.
Can I make the screen state where it is after a control is auto postback? And how?
View Replies View Relatedi have an aspx page. on that page there are three textboxes. when the controle is in any textbox and i press enter,the page is postback to server. i want that when i press enter the page does not postback to server. how should i do that?
and i want to know what is the javascrtipt event fired when ever enter pressed in asp:textbox.
Say I have a textbox (autopostback=true) and a button. I enter a new value in the textbox then - without clicking anywhere else first - I click the button. The box's text isn't changed prior to the button's click so the new data in the box isn't evaluated at the server. The user has to click the button twice.
I would like to change this without any scripts on the client that will be rejected by security setting in today's browsers.
Using a VB aspx web form I have a TextBox web control and a DropDown List web control that both AutoPostBack to the server when their state has changed. When the user is in the TextBox, changes the text and using the mouse selects the drop down list control, the view state is destroyed and a blank screen results.
When the user has changed the text in the text box and moves focus off the text box using the tab ke the page does the postback with no problems, but when the focus is changed by using the mouse to click on the dropDownList control it to tries to do a postback at the same time.
Am trying to restrict user from entering non ASCII character in the text area. Say if the user entered non ASCII character then on the form post back it should show them the message like:
"non ASCII character between the word1+word2"
I have just moved an ASP Classic website to a new hosting company that has a
number of .NET components available. The website works fine after the move
with one exception. We were creating PDFs using ASPPDF for ASP but now it
looks like only ABCPDF.NET is available.
My knowledge of ASP.NET is very limited at this time and I am planning on
converting the site to ASP.NET soon but I really need to get the PDF working
as soon as I can.
I am trying to add a Visual InterDev project to Visual Source Safe 6d.
Normally I just go up under Project | Source Control | Add to Source Control
and I can load the project to VSS but now when I try to add the project to
VSS I get the error:
"Cannot establish source control for the Web Application. The server does
not have a source control system installed on it, or the user name is not
recognized."
I am on a workstation which has VSS installed. VSS is also installed on the
web server istself. I atttached to the VSS database as "admin" and under
my own user name but I continue to get the same error.
What could be wrong? Perthaps I am using the wrong version of VSS. Is
version 6d compataible with Visual InterDev? Or do I need an earlier
version?
I am developing on WXP SP1 with VS.Net 2003 and VS6 installed. I cannot get
my localhost webserver to render any classic ASP pages. ASP.Net and standard
HTML works.
If I request an ASP page from localhost the browser hangs for several
minutes before just doing nothing. The status bar says the website is found
but nothing is ever downloaded.
I have verified the mappings in the IIS manager and I have re-registered the
ASP.DLL. I am now at a complete loss.
The following code works on IIS 5.0 on a Windows 2000 server.
Response.Clear Response.ContentType = "application/rtf" Response.AddHeader
"content-disposition", "inline;filename=letter.rtf" response.write l_strBuffer
But on IIS 6.0 running on Windows 2003 server we get an error.
"Internet Explorer cannot download <file name>.
Interner Explorer was not able to open this Internet site. The site is
either unavailable or cannot be found. Please try again later."
After increasing the AspBufferLimit attribute in the metabase.xml, we were able to resolve the issue.
Is there any other way to resolve this without modifying the metabase.xml?

View Replies View RelatedI'm migrating a classic ASP site from IIS 6 to IIS 7 and I'm finding some minor problems that I'm assuming are IIS 7 config related. The problem I'm concerned with right now is that when I run the asp pages, they have lost all their image and CSS links. Functionality is fine (that is I can query the DB, update records, etc) but all graphic features have been lost. how to solve this issue?
View Replies View RelatedDoes anyone know for sure whether classic ASP (ASP3 ?) will run on Longhorn?
View Replies View RelatedI've been working in .NET for some time now and I don't remember specifically
how asp classes are cleaned up in classic asp. I've been put on a Classic
ASP project(ugh) and we're having some serious stability problems. Once we
reach a point of sustained CPU useage of over 80% IIS 6 restarts the w3wp.exe
process which of course terminates all sessions and resets the website.
I've
noticed that the previous developer has an include which creates a couple of
class objects in ASP. Not third party or "CreateObject" objects, but ASP
classes. This include is in A LOT of files and the classes not being
destroyed in any of them.
My question is could this be the problem? I seem to remember a problem with
ASP classes and not destroying them causing leaks of some sort. I need to
mention that the memory doesn't seem to be leaking but the CPU utilization
goes wacko as if ASP/IIS is corrupt. My environment is Windows 2k3 and IIS
6. The previous environment was Windows 2K and IIS5. Both environments had
the problem.
Before I go through these hundreds of files I was wondering if anyone
remember what the problem was with ASP classes not being destroyed.
I am using ASP, and I would like to read the country of origin from the HTTP header information of my visitors. I would use this to geotarget different ads to visitors from outside the US.
For other reasons, I don't want to use a solution like GeoIP - I want to do it through ASP code if possible. Has anybody had any experience with this?
I have a system written in classic asp and a lot of Javascript. Due to
its performance and security issue, we decided to re-write this big
module. I heard that C/C++ has a better support in performance and
security (relatively) but here comes my questions:
1. Can ASP talk to C/C++? Because from my experience I use C/C++
mainly for application console.
2. If I want to exclude most of the Javascript and use other
programming language instead, can ASP.NET do it? Is there any
compatibility issue between Classic ASP/ASP.NET/Javascript?
Does anybody out there consume a web service using classic ASP?If anyone has any useful resources for doing this, I'd love to see them. I haven't found much online at all. Long story but I'd rather not have to learn .net or switch to php for this one project
View Replies View RelatedI'm maintaining an ASP Classic file that has HTML withing
Response.Write methods such as
<%
Response.Write "<table><tr><td>"
Response.Write testVariable
Response.Write "</td></tr></table>"

Would their be a performance hit if I were to write this instead?
<table><tr><td><%=testVariable%></td></tr></table>
I need some confirmation.
What do y'all see for the future of ASP in light of MS decision to replace

Has anyone had any success in editing/debuggin classic ASP in Visual Studio 2003?
We have recently received a new project from an outside contractor done in .Net 1.1 and now have VS 2003 installed. We have tried to use it to work with our legacy ASP applications but we are stumped on how to get the debugger to work. It keeps trying to "build" and errors out because it cannot find a sub main().
If you have had any luck with this please either point to a resource that will get us started or share the steps to get this going.
Trying to create a mini-ASP web dev with a couple of PCs at school. When the teachers are happy with the site on the LAN then going to upload it to the school site. Problem is having real problems with the ASP side of things.
Timeline of events is as follows:
1) Added IIS (via Add/Remove Windows Components) on WinXP Pro machine (6 month old Acer to be exact). No problem.
2) Created a folder called asp in the inetpub folder and made it web shareable by right-clicking on it and setting the Web Sharing bit. I usually have read, execute and directory browsing. No problem.
3) Put a text file (with an ext of .asp) in this new asp folder, typed the usual text of <%=now()%and saved it. No problem.
4) Went to http://itpc1/asp and clicked on the new 'test.asp' file. Date and time appears. No problem.
5) Went to my colleague's little office (showing him how to do asp) to make sure his PC can see the web page working OK (both machines are on the same network) and the page displays fine. No problem.
6) Now the reason for this setup is that the PC in his little office is only WinXP Home and the PCs with WinXP pro on are the children's suite, which he can't have sitdown access to all the time. My plan was that I would web share the asp folder AND network share the folder so that he can be dropping files in and doing edits on the asp folder via the network share and then view the results via the http://itpc1/asp web share.
Proceeded to network share (all are setup for simple sharing) the asp folder. No problem.
7) Went into network places on his WinXP Home PC, found the folder no problem, created a shortcut to this folder no problem, he can open up, edit and save changes no problem.
HOWEVER, as soon as he goes back to the http://itpc1/asp page all of the asp files generate an ASP error saying the Invalid Default Script Language.
I go back downstairs and try and get the pages via the main WinXP Pro machine and this now generates the exact same problem.
The long and short of it is, I have to uninstall and then reinstall IIS to fix the problem. Nothing in the IIS settings has been changed. I never touch the default scripting lang setting, which is in fact the right setting of vbscript.
Could somebody please let me know what is happening. Why is the XP Home PC screwing things up when the files are network shared on the WinXP Promachine?
I'm using classic ASP with VBscript and I would like to have a facility for XML object serialization, just like the Serializer object that is available in ASP.NET. Is there such a thing for classic VBscript.
View Replies View RelatedI have tryed my best to understand the asp.net, but the visual of asp.net pages are the most complicated, because on asp we have total control over the layout the page, on the asp.net for example we have a lot of components, like tables wich already have paging, etc.. a lot of code must be rewritten.I am having a lot of dificulties to try converting my asp projects to asp.net... what do you think about this?
View Replies View RelatedI have scripts on a server that awhile back had new option/server packs installed (to accomodate security and net framework issues) and my classic asp date references
"Date()" and "Now" will sometimes flip flop the formatting of the date from 10/3/2003 to 3/10/2003 (european mode).
What would be a good way to use an include file to perhaps an asp.net date object, or where would I find a good reference to using an aspx file to calculate and display the date properly so that I can avoid this flip flop snafu of the date formatting.
I am looking to learn Classic ASP and was wondering if anybody could recommend any good books for learning Classic ASP from scatch.

I haven't, but before I upgrade to Vista I would like to ensure all my websites will work once I do. What version of Vista is best to use (and includes IIS) ? What problems did you have with database connectivity ?
is there a way to open an app from Classic ASP? For example, I want to open the file "calc5.xls" on the server when a particular webpage is opened.
