I assume it has to do with cache control, but how do I prevent the form from clearing when a user hits the back button? The form I am referring to is my registration page. After the registration is submitted, they are taken to an error handling page. If an error comes up, they are required to hit the back button and correct the mistake.
It seems like for the most part it retains all of the information in the fields, but occasionally it clears it out. How can I prevent this?
I have a page that creates a cookie on your computer. at that point it stores login information. Seeing that I am on the administration side and wish to login to accounts without the cookie getting in the way, I create a page to delete the cookie as follows:
Response.Buffer = True
Dim Cookie For Each Cookie In Response.Cookies Response.Cookies(Cookie) = "this must be something!" Response.Cookies(Cookie).Expires = Date() - 1 session.clear session.Abandon() Next ' Cookie
For Each Cookie In Response.Cookies Response.Cookies(Cookie) = "this must be something!" Response.Cookies(Cookie).Domain = "hazsoft.com" Response.Cookies(Cookie).Expires = Date() - 1 session.clear session.Abandon() Next
This removes the cookie like i desire but, I must first reopen my browser for the cookie to be totally removed. As you can see I have also removed the session variables. Is there a way to remove cookies and session variables, without having to close the browser window?
The code below isn't clearing the cookie and sessions. It is used in my shopping cart to track the user and the items purchased/added to the cart. After making a purchase you are directed to the receipt page (where this code is). If you go back to the main site the items still show in the cart. Any thoughts?
' The below lines clears out the users cookies to allow for additional orders Response.Cookies("customerid") = ""
(this part seems to work... when clicking refresh the proper error message is displayed etc.) ' The below lines clear session values to avoid duplicate ordering using Refresh session("cust") = 0 session("cartID") = 0
Is there a way to clear cache using ASP, VBScript or Javascript?
I have created an ASP login page with sessions etc so unregistered members cannot view certain pages, however, when you logout you can still press the back button on the browser toolbar and view the pages, I want to find a way to make those pages expire by clearing the cache or something like that!
Does anyone know how to clear a sites cache with ASP. I have a login script that does not terminate the history when signing out. A user can simply click the back button and get back into the site..
I have a form with 4 different Submit buttons. In the action code, I do a request on the button names to see which one is valued. This all works great, until the browser is refreshed -- the request shows the name of the last button pressed. Is there a way to clear all the buttons so they don't appear to have been pressed when they've only been refreshed?
Im useing Access, and trying to clear the table before i write to it, and to be able to keep it all on one page? Trunicate table or something like that? This is waht I have so far but doesnt work. Code:
I searched the forum and got the following code from someone who posted it in 2002. However I can't seem to get it to work in my asp page. Can someone confirm the syntax for me? I would like to try and put it in an include file rather, but need to get it to work first.
I have a form that comes up pre-filled with database results for the values. I'd like to add a button, though, that will clear all fields to start blank if desired.
A standard "reset" button, will only clear input that has been typed in, but won't clear the initial values. Does anyone have a script already that does this or could someone get me started on how I could do this?
I am trying to run and UPDATE, INSERT and DELETE SQL statements to update append and delete data from some tables in access. Here is the low down:
I want to update All of the fields from a table called TEMP into a table called POSTPONED, WHERE the 'postponed' fields = "False"
I want to then go on and clear the records from TEMP that have the field postponed = "false"
And finally i want to again append the remaining data in the TEMP folder into a table called RESULTS.
Does any one know how to do this or what the SQL statements should look like, i have tried writting them, no luck, i have tried generating them in Access but no luck because the ASP is erroring me on them and i dont know what its chatting about!
I have a form that on clicking of the Update button first updates the specific record in the db, then Inserts if the vMemo field is not empty. The problem that I'm having is that After updating if you hit the [F5] key (refresh) it inserts another record ...
I have tried:
1. Clearing the vMemo field after the insert is done (vMemo = "") 2. Setting the value on the form for this field to ""
Neither of these are working. It's not displaying it on the screen but it is holding it in memory (I guess). Any way to clear this out after update/insert?
I'm just dipping my toes into server-side scripting.
The Global.asa file seemed really nice, but am I understanding correctly that the application onstart event is fired ONLY when the server is started/re-started or when the FIRST user logs onto an ASP application?
If that's the case, then all the changes I keep making to my Global.asa file are pretty useless, right? (which seems to be the case -- i.e., my pages are not using any of the new information). Code:
I am a webdesigner.We have recently taken over a site created in ASP. The site remains on the original server, but my company does the updates on the site.I do not touch the ASP at all, as I not familiar with it other then I know ASP automatically becomes html when you view it from the browser and u can save the file from there.Anyways, I edit the pages as required, new text, new photos, new links, and create new pages (any new pages I create in html if not tied to the database). I save the pages with a .asp extension and upload. This does not seem to mess anything up. The person who hosts the site, is upset that someone else is editing the site, so he's really not easy to work with. Anyways, after uploading files, everything works fine, and then a day later, all of a sudden, any .ASP pgs you click on give the following error or similar pasted below. What I'd like to know is if these errors are because of me..and if so, how do I prevent it.
I've got an intranet application that presents a list of files in sort of a 'central repository' web page. Each file is an href in the form <a href=file://server/share/path/filename.ext>.
When the user clicks on an excel file,it is opening within the browser,which unforntuntely confuses the heck out of them because the usual Print/Print Preview menu options are not available. I would like the user to be presented with the typical Open/Save dialog when clicking on this link.
Is there any way that I can force the browser to do the same thing as 'Save Target As', without modifying the user mime configuration in IE (another common suggestion), or hosting the files on the web server?
i have a form by asp and database by MS access.so i want to prevent the duplicate value in empID because when i add a new employee with the same id ASP gives me this error.
Error Type: Microsoft OLE DB Provider for ODBC Drivers (0x80040E14) [Microsoft][ODBC Microsoft Access Driver] The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again. /employee/admin/addemp1.asp, line 48
so i want the employee to get a message like this empID already exist or somthing like this.
If you look around on the web for advice on cache-control and using 'Option Explicit' you get a paradox. Both features are supposed to be the first piece of ASP code on the page. Well they can't BOTH be first can they?
What would the logic be to prevent flooding? On my forum they have a timer, so if the user has submitted a post, it starts the timer, and after 30 seconds it will allow him to post again.
When the user comments, record the date in a session (StartTime) and when the user tries again, DateDiff in seconds to see if the Now() time is more than 30 seconds after the StartTime. If it is, clear the session.
i tried to open Window B using window.open() from Main Window. And from Window B i open another new Window C which fires up session("topic")="something"
So i tried to open another window link from Main Window, and the session("topic") value is still the same. how can i overcome it? Beacuse im using same session("Topic") var for all the sql query statement. so if 1 window is opening and another different session window start, it will overwrite it each other.
How can you prevent the database error from displaying on screen? Can you redirect users to a more friendly error screen that is custom created. Using ASP/SQL Server. For instance, if the database cannot be found, instead of displaying,
Microsoft OLE DB Provider for SQL Server error '80004005' [DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied. /myConn.asp, line 7
Can you make it to where you could display something like this:
"I'm sorry, a database error has occured, please try your request later, click hyperlink for list of possibilities."
Currently i am doing a file management project where user are able to create folder and upload files to it. The file ownner would be able to set permission (from database linking to the file path) if a user able to download it or not.
*each file info will be stored into a table e.g. fileid, filename, path, access.
Now i am facing a problem where if a user does not have permission to click on the link to download, the user can guess the path and the file name and directly type the path on the address bar to download the file.
I have a form which when submitted will validate the fields and then add the record to a database. If a mandatory field is not completed, there is an instruction to return to the form and complete the mandatory fields and then submit.
The problem I have is preventing the user from resubmitting the same form once it has been added to the database. I cannot deactivate the submit button, because if they need to return to complete mandatory fields, the submit button is still required.
I have read the article "Programming Forms To Submit Only Once" from 15seconds.com and this looks exactly what I need......
To prevent the same form from being submitted more than once we must:
Initialize the data structures. Create a mechanism to give each form a unique identification. Find a way to store a list of already submitted forms. When processing a form submit, we just have to check if its ID is on the list.
I am having problems when adding the recommended code to my form and my process form pages.
This may not be possible on the server side, so apologies if this is the wrong group for this post.My form consists of an unknown number of pairs of text boxes. They are named textbox_a and textbox_b. I then split the comma separated list that gets posted:
textbox_a = split(Request.Form("textbox_a"),",") for i = ubound(textbox_a) ...insert into db
then do the same for textbox_b
If anyone puts a comma into one of the text boxes, this will result in unmatched pairs. How can I deal with the comma, or prevent it?
I want to prevent multiple logins in my web application. For eg:If a user "userA" logs into the application,some other user with same userid "userA" should not be allowed to login as long as previously logged in "userA" is active.
Is there any solution? One method I thought was when user logs into application, I set a flag in table.If user logs out of application from the logout button explicitly provided in application, I reset the flag for that userid.But if user closes the application from browser(close) , I am unable to find a way to reset a flag.
due to my 'Language for non-Unicode Setting' in Regional Settings,my ASP page keeps outputing the date format as Chinese Simplified characters when issuing say, <%=Now()%>. In addition, my client script also interpret it as Chinese characters, which I don't want it to behave this way.
However, I can't remove my 'Chinese (PRC)' settings in control panel as I need it for other Chinese version software. Does anyone knows how can I display the date in my ASP page in normal English? I did try out the META tag Content Type and put in several charset to try out, but seems like it doesn't work at all.
I have a file that SHOULD only be made accessable to registered users. They must login to get to the download page. The problem I have is that once a user logs in an gets to that page they can potentially share the web link to that file with anyone and that unregistered user can bypass logging in.
I was thinking something along the lines of download.com where when you click download, the actual files location only appears for a split second, pops up the download box, then it switches to another webaddress?
