How Do You Detect When A Page Has Only Been Refreshed?
I'm trying to write an ASP interface that mimiks a .Net datagrid control.
I'm having a problem when I'm in the middle of an Edit, Update, or a New
Record.
If the user hits the wrong button, the program grabs the values in
the textboxes using the request.form() and then redisplays them in the
textboxes when the records table gets written back out to the page. This
works fine as long as the form is submitted.
If it's just a page refresh
(F5), the program doesn't get the latest changes to the textboxes and
displays either a blank or whatever was in there the last time the form was
submitted. Anybody got any ideas?
First I would question why you want to do this. If they get to the page by any means it should respond appropriately, whether refresh or by link. This is a stateless environment after all.
That being said...
I would take the approach of setting a session variable that gets set the first time they hit the page:
<% if session("NotTheFirstTime") = "" then 'write the onload session("NotTheFirstTime") = true end if %>
then based on that variable write or don't write the onload.
Of course, if the user can access the page from multiple links and the onload is valid for each link, regardless of how many times they hit the page, this won't work....
I have a function in a script file that I use from a couple of different pages. Can I, within the function, detect which page is being viewed (which page called the function)
I have an online application made up of ASP pages (IIS 5.0 on Windows 2000 Server) drawing data from a SQL Server database. Most of the time, everything works exactly as it should. Connections are opened to the database, queries are run and data is returned and writen out, connections are closed, etc.
However, every so often a page simply won't load. It isn't trying to load and then timing out or anything, it's like it's ignoring the page entirely. It shows the correct URL in the address bar of IE, but there's nothing but a blank white page displayed. Viewing the source of the blank page reveals that instead of the correct code for the page, we get this: Code:
we're running IIS 5 and trying to do a simple update to a code behind file (Login.aspx.vb) we copy the file over to the server, but we're not seeing the updates. the server is still reporting errors on line numbers in the file that no longer exist. we've even stopped / restarted the service, with no luck.
i've created a simple web app that allows users to enter in information about a project in a web form and save that information to a database (Access). After a user enters in all the information, she can click on a link to go to an index.asp page that displays all the projects that have been added.
the problem i'm having occurs after the user enters in all their project information. when the user goes to the index page, the index page is suppposed to retrieve all records and display them, but it doesn't.
even after hitting the Refresh button in the browser, it won't display the latest project that the user just entered. however, if i add a second project and then go back to the index page, it will work fine and display both the first and second projects. so, it's like the first project won't be displayed until i enter in another project after it (like the first project is stuck). does anyone know what the problem may be?
I have a web site where I use cookies to navigate between the pages. The cookie is his id no which is nothing but his staff id no. All most all pages are dynamic and connected to sql server 2000 through ADOs. My problem is :
if any one logs in and enter bowse the pages and goes back uses other log in his old page is displaced rather than new one, untill he explicity uses the refresh button. Once he does that , it is working. Iam using javascript menus to navigate between pages.Previously when menus are not there pages were working fine.
Is there a way for asp to know what url is in the address window? I have a function that is included in every one of my pages and I want it to write out different things depending on the page the visitor is on.
Can anyone tell me how to detect a ip address behind a router? I know that using ASP, we can detect the actual ip and the proxy ip, but what if the visitor is using a router that dynamically assigns a ip.
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.
How can I get the url of a page in asp and detect if there are no variables appended to the end? Would I somehow get the address and do an instr for the ? character? Code:
Could anyone show me a tutorial or like show me a script in asp that can detect to see if the mysql backend is working? And if it isn't then to display a message that says something like "out of luck."
Is there a way whereby i can detect where the user came from?
For example:
if this user came from www.mywebsite.com/a.asp theni will redirect him to c.asp but if he came from www.mywebsite.com/b.asp then i will redirect him to d.asp
I need to add in some specific browser detection in my ASP to identify Mac IE5 running OSX - is there any wahy of identifying this config alone - and not just identifying all Mac IE5s? If you have OSX Mac IE 5, please visit this page which will give your User Agent string.
The delete method of the FileSystemObject.FileObject does not return a result. If permissions disallow deletion, it will not raise an error. Conversely, if the delete method does succeed, a call to FileExists directly afterward may return true because the system hasn't updated yet (or whatever actually goes on). Is there any way to accurately check the result of a deletion?
I searched around everywhere on the net, but could not find a simple example of detecting if cookies are enabled - on server side, and without moving from one page to another.
This should be a very basic functionality, so I am reluctant to believe that there's no way to simply test it in a server-side script.
I've been working on this wysiwyg web editor. The editor lets you upload images. Only .jpg, .gif and .png files are allowed. Now I should be able to detect if the uploaded .jpg image is in RGB or CMYK mode. Only RGB images should be allowed. Can this be done with ASP?
Im writting an asp app that tracks the users scores and info (its a training app) to a access database, ive disabled the ie toolbars and everthing so the user must use my nav buttons so i can track what pages they have been to. My problem is if the user closes IE with the close button [X], is there a way i can redirect them to my close database and save results page, i cant use the unload event as this is trggered every time the use goes to the next page.
This is fine for displaying the text, but the text contains links which are currently just being displayed as text. I'd like them to display as hyperlinks that will open in new windows when clicked upon. so basically I need some ASP code to detect text starting with http:// or www.etc and automatically make them into hyperlinks.

Is there anyway to detect the ActiveX control is able to run on the browser or not. After I installed the ActiveX control to my system, user sometimes switch the secruity setting to "not able to run ActiveX control". So, the ActiveX control just show on the broswer, but not able to run it.
I want to find a way to detect it. And prompt the user a message telling that the ActiveX control is not able to run.
