I have a permission tracking app that I am working on, and I have made the insert page for it. I am having issues on how to prevent duplicates from getting entered.
Currently the interface for the app has a mixture of select boxes, list boxes and checkboxes. The form submits the page to processAIMR.asp and then does the inserting. I am using a loop to insert a new record for each checkbox checked or listbox entry selected. Code:
I have a string value which has the bellow content.
Dim aString as string
aString = "1,2,4,2,2"
where aString is a parameter set dynamically based on the user loggin into the system. Now All I want to do is to eliminate the duplicates. ( In this case I need to keep only one "2" and remove the remaining "2" , so my final string should be "1,2,4" ).
How could I do that. I was thinking of an array, but the issue is, If the "aString" is empty I believe array will return a error. So any other way of doing ?. Or simple asp functions which will eliminate this.
A member logs on and enters a record, if one already exists for that date, then they get a message saying so. If not the record is added and some text is displayed. But it still allows me to enter records even if one already exists! is it because I am storing my dates as strings? Code:
arrColour = split("blue,blue,green,red,purple,blue,green,yellow",",") What I need to be able to do is to remove all items of the value "blue" from the array. I can just run a dictionary function to delete all duplicate values, because some of them need to be retained. I just need to delete all of them of a particular value. how this can be done?
I have declared a multidimensional array as follows. dim parray(100,5). Now this array contains some duplicate values. So how to remove duplicate values in this multidimensional array.
I've got a form that allows the user to search a table for data and if it finds that the data is not there, it should insert what is missing into a new table. But I'm not sure as to how I would check the records before I insert records. Code:
There are thousands of records in each. I need to check for duplicate email addresses across the two tables and remove them from tblSaved if they appear in tblNewsletter.
I have an array which is made up of a selection of place names, such as "London, London, Lisbon, Paris, London, Madrid, London, Madrid", what I need to do is loop through the array and get it to find out which item is duplicated the most times, and then have this item equal to a variable, such as TopPlace, which in this case would be TopPlace = London, I have no idea how to achieves this, could someone offer me any help on doing this?
i have created an array from recordset containing user names eg. (davidp, davidp, evenf, patricka, rebeccah). which i have sorted in alphabetical order, but i need to identify duplicates in this array and the number of times it has been duplicated.
I am pulling some records out of a database which have a Description field containing several words, and storing this information in an array using GetRows().
Then using a for-next loop I am going through these records and using the Split() function to get the first word of the Description and then adding it as an option to a dropdown list.
The problem is I get lots of duplicates in the drop down because lots of the descriptions have the same first word. Using DISTINCT in the SQL statement won't help much because at that stage the descriptions arent the same. Code:
I'm using if for when the user deletes a record from the database. People using the website try and delete more than one record at a t time by placing commas between the IDnumber ie. 1,2,5,9 etc.
This creates an error. So instead of this error appearing, how can I get a small alert box telling hte user he/or she has entered the wrong data type?
I am returning a list form a db: this could be 1,2,3,4,12,67,1,2,34 so basically I am looking at how to remove the duplicates before doing another select. I saw a thread here with a funciton to do this bu it does not seem to work.
In ASP classic pages,I want to know if it's possible to prevent session variables from becoming zero length strings? I have tried setting the Session.Timeout to a large value, but alwas, after 20 minutes, my session variable times out. I also tried setting the session timeout in IIS manager to a high value, but this did no good either.I just want to allow one particular session variable to last a long time.
Does anyone know how to prevent the browser from automatically adding the password to a form after a user name is entered? I need to be able to over ride the brower setting so turning off the option in IE is not really a solution.
I have a form that sends info to a preview page, then to a thank you page. The thank you page gets the data passed from the rpeview page and sends an email.
How can I prevent the user from refreshing the page, so it doesn't send the email again.
I would like to prevent a user from logging in with their user/password combination on a different computer or even a different browser window, if they are already logged in. I have a login page, from which I use a DB check to verify user/password info. Also, I have a bit loggedIN field in the DB, which I use to see if they are currently logged in; if so, I prevent them from logging in a second time.
Unless they click the "Log Out" button, then the DB value does not get changed. Any suggestions as to how I can log them out, even if they simply close the browser window or jump to a different page?
For instance here's a simple select statement Code:
("SELECT a, b,c d, e, f FROM Table WHERE a = "&CInt(j)&" and c= 0")
j is a dimmed variable which is a and it's numeric. Is the above protected against any non numeric instances? Like j=2,345..i've tested this and it works i'm just trying to see if i've covered all my tracks.
How do people go about preventing the user from submitting a form for a 2nd time? For example, the user submits a form, clicks on the back button, and the submits the form again. I have used various techniques in the past (depending on circumstances) but I'd be interested in the techniques you guys currently use.
Is there a way in ASP to prevent including the same file more than once?
Example:
dbutil.asp needs constants.asp, so I include constants.asp inside dbutil.asp.
transact.asp also needs constants.asp, so I include constants.asp inside transact.asp.
transact.asp doesn't need stuff in dbutil.asp, and dbutil.asp doesn't need stuff in transact.asp.
Then later I might have a main.asp that needs both dbutil.asp and transact.asp. So I include them both. However, the constants.asp will be found to be included twice!
What can I do to creatively prevent multiple inclusion of the same file in ASP? I know how to do it in C and C++, but I can't apply that to ASP, it seems.
I have created an Intranet in my office using ASP (of course). Within it is a booking system, allowing booking of conference rooms, digital camera and other equipment. It works perfectly...almost, as there is no way to prevent double bookings.
I really don't know where to begin with this one. All bookings go to an Access DB, into a single table. The bookings have a start time and an end time (24hr).
I would like it so that when the user submits the form, if there is a clash in times instead of saying, thanks for your booking, to redirect them back to the booking page saying there is already a booking for this time and that I am very sorry!
I guess I have to check some value in access and return the info back to the webpage before it chooses where to redirect the user.
I am developing a Simple ASP Website with a login page. I want to know how can I change Session ID after login and also Close the current Session after User closes the Window or gets logged out of the Website. So that every time user logs in into the website, Session ID will be unique.
My client received an email from a user who mentioned that by accident they had been typing (over the querystring I guess), and the url had become:
default.asp?pageid='asd
They then received a SQL Server error message.
My client contacted their webhost, who came back to them promptly and talked of 'SQL Injection', they said that we would need to secure the code as well as the permissions on the database(which I believe they have done)..
This is something I had over looked, and started to write a fix for a couple of nights ago...but I dont think its 100%....
Basically I now do this at the top of my default.asp page ...
I've seen plenty of articles and utilities for preventing form injections for ASP.NET, but not too much for classic ASP. Are there any good input validation scripts that you use to avoid form injection attacks? I'm looking for good routines I can reuse on all of my form processing pages.
We have 2 domains for internal purposes: one for users (have to login and domain has SSL) and another for sponsors (have to login and domain does NOT have SSL).
Now when a user logs in and there are pages that have info from the sponsors domain, users are asked to login again with a warning message saying if they want to see secure and nonsecure information. How can I bypass the second login? Is there something I can do in active directory, IIS, or ASP to not have the second login appear?
How can I prevent this from happening? For example when the asp application works in a public terminal where we don't want successive users to know the login password and user name of the previous ones?
i have a SQL text field that has linebreaks in it, when i try to display the field in my java/asp script it doesn't work. so i'm thinking i need to replace my linebreaks with <Br>? is that what i need to do? Code:
