View 4 RepliesI am using a create User Wizard for registering a user and have converted it to a a template to capture additional information. In the CreatedUserEvent handler in Code Behind I am getting the UserName of the new user and their unique GUID key. This is then added to a seperate data table with addditional info captured from the user. The textboxes within the create user Wizard have validation controls. If the user has missed an entry these fire and it shops the process of creating the user.
BUT If I then complete the textboxes and then click submit it says the USER NAME already Exists! This is not what I want as the User just needs to correct the errors in the form and they should be able to keep their iniital User Name choice. Do I need to change the Event handler and if so am I still able to capture the USerName and Key so that I can add the data to the other non membership table.
I need to upload a file (xml, pdf, etc) from the user's PC, but I need to write it directly to a file server. I cannot use FileUpload because there is no way to direct its initial upload to anything but the web server. So, how do I use the HTML INPUT to upload the file from the user's PC directly to a file server located at a different URL than the web server the web page is being hosted on?
View 2 Repliesim creating a multi step create user wizard for new members but I run into a problem. If the create of an account is in step 3 how do I capture the values from step 1 and 2. Should I try to pass the values to sessions or is there some other code. Here is some codebehind I tried so far (did not work).

View 6 RepliesQuestion:
I have a web interface where a user can upload an XML file, which then gets imported into a SQL database.
Import works fine, interface works fine, logfile works fine. The problem: The user doesn't get any progress report until the entire file has been processed... Is there any way the server can output logfile messages to the user page while processing? I mean AJAX doesn't work for server side calls to the client, only vice-versa, or is there a workaround ?
I am wondering what the best strategy is for accepeting http uploaded files on a web server in a safe way? I have access to scanning software which will quarantine suspect files, but not really sure what the best practice is for this kind of thing?This is somewhat of a pest as the form data and the uploaded file form a logical unit - the fact the files must be scanned (pottentially quarantined) means I would need some kind of callback, post upload mechanism for handling this.
Is there a preferred way (or peice of software) for handling thsi kind of thing?Happy to elaborate of anyone wants to comment or assist? I'm aware I can limit file size, file extension etc, so really just concerned about stopping viruses entering the web server and/or network. And I guess to do so in awy that allows me to interact with scanning software such that I get feedback in relatively real time??
I want to limit the allowed uploaded file types to images, pdfs, and docs. What is the recommended way to approach this?
I assume checking the file extension alone is not enough, since an attacked can change the file extension as he wishes.
This is basically for a course management system for students to upload assignments and teachers to download and view them.
I'm doing a project in component management system. I need to block executable files from getting uploaded. Blocking should not be based on the extensions. For example, i've a file named abc.exe i'm going to change the file extension to abc.jpg in this case that abc file should not get updated. Similar to that in gmail file attachment.

View 1 RepliesI am using FileUpload control to facilitate Image file upload on my website. I want to restrict a user to upload only Image file. I am using
if (fupFirmLogo.PostedFile.ContentType == "image/Jpeg")
{
}
to check if the file is a image or not. I want to allow all image extensions like PNG, GiF, Jpeg, tif , BMP etc. How should I do it.
I made a website for a friend and he uploads a lot of pictures, around 20k per month. And sadly, I made it so he has to upload 1 at a time, because when they are uploaded they are renamed, attached to a group id and watermarked. Is there a way to allow him to select all 20 in a group and have them be uploaded and processed? I've looked into a couple of way to do it, mostly flash, and that will not work since we are renaming and added the newly created name to the db. Adding addition upload controls is not a solution. If we need to make a desktop application that does the uploading, that is alright as well, but we'd like to keep it all in the asp.net environment.
View 1 RepliesI've an application built on asp.net 2.0. There is an option for user to upload excel file. Once the file has been uploaded the data in the file is validated against some business rules. Rows that successfully validates are inserted into database as soon as it is validated.
I use ado.net to connect to excel file. And use data reader to iterate over all the records. Normally the number of records range from 5,000 to 20,000. This process takes good 8 to 10 minutes. I want to optimize this process because to my understanding it takes too long. Currently I am looking at OPENROWSET, OpenDataSource which so far is unsuccessful. Valiation that takes place on every row is very simple. I only checks for maximum length. So validation itself is not an issue.
I want to limit the allowed uploaded file types to images, pdfs, and docs. What is the recommended way to approach this?I assume checking the file extension alone is not enough, since an attacked can change the file extension as he wishes.I also thought about checking against MIME Type using PostedFile.ContentType.I still don't know if this is adding any further functionality than checking against file extensions alone, and if an attacker have and ability to change this information easily.This is basically for a course management system for students to upload assignments and teachers to download and view them.
View 2 RepliesIam using a file upload control for uploading files in my asp.net application. iam using the following code to impersonate the users who do not have permission for the files to upload. The code works fine for all the files, but it is not working for the files which are in desktop.
Code in .cs file:
System.Security.Principal.WindowsImpersonationContext impersonationContext;
impersonationContext =
((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate();
//Insert your code that runs under the security context of the authenticating user here.
impersonationContext.Undo();
In web.config iam using the following:
<identity impersonate="true" />
I used the Create User Control to make a new user.
Is there a similar tool (I did not see one) that allows the user to edit their own profile?
If not what is the best way to do it? I have created user tables in AWAT.
