    replied to Server-Side CSS on Page Load
    in ASP .NET
    My apologies, I just checked the w3 specification for the anchor (a) tag:
    Code:
    <!ELEMENT A - - (%inline;)* -(A)       -- anchor -->

      Server-Side CSS on Page Load

      Very quick question.

      I have a master page (M1) and three content pages (C1, C2, C3). In M1, there's a list of three anchors (A1, A2, A3) which point towards the three content pages.

      The anchors have some CSS to make them look pretty. I'd like to be able to dynamically set the CSS for A1 when I navigate to C1 so it looks slightly different to the other two (e.g. to indicate this is the currently selected item).

        ASP.NET DataGridView Sorting Problem

        OK, this is rediculous...

        Surely, sorting should be one of the easiest things with the ASP.NET DataGridView control. I mean, there's hundreds of sites out there (Microsoft MSDN entries included) which explain and give examples of the DataGridView sorting and how to make it work...

        SO WHY CAN'T I GET IT TO WORK?! Dammit!

        Apologies for the rant. I'll try and keep it to the point from here on in:

          For anyone who's still interested, we have managed to find a way around this problem.

          Basically, there is a way to mark a .NET object as "safe for scripting" via the registry. We looked into implementing IObjectSafety, but because this is a legacy VB5/VB6, this didn't seem to work on our .NET assembly (although we found that solution on the internet somewhere and it seemed to have worked for others).

          However,...

            Am I right in thinking that ActiveX controls cannot be written in .NET? I have a feeling my company is trying to move forward with new technology (at any cost...), so this idea would not go down well with them! Surely there must be a way of doing this without using ActiveX controls?...

              Thanks Frinavale. That's another option for the user that we've already implemented, but the product has to be able to do everything the thick-client predecessor was able to do (one of which was interface directly with their scanner), so we have to be able to offer both options.

              Thankfully, the upload system is working fine, so the customer is currently using that option as a workaround until this scanning stuff is sorted!

                Hey man, you were right.

                I've done a full experiment to try and determine if any of the IE settings would affect the way the assembly is downloaded or run, and it turns out .NET assemblies can be prevented from being downloaded using the ActiveX security settings.

                Interestingly, the final solution is to ensure the following setting is switched on:

                NET Framework-reliant components
                Run components not signed
                ...

                  Plater, thanks for your reply. I am aware of the .NET Framework security settings, so I have an MSI which is rolled out to each client machine. The MSI, when run, sets up the .NET security settings on that machine to allow my particular signed assembly to run under "Full Trust", so that shouldn't be a problem.

                  The client machines only have IE, never Firefox or any other browser, so that's not an issue.

                    What could prevent a user from downloading a .NET assembly embedded in a web page?

                    I have a .NET assembly (ScanControl.dl l), which accesses a scanner on my client's local machine and allows them to scan a page (Scan()).

                    I have an ASP.NET web application with a page which will (theoretically) use this control to allow a user to scan a page into my database (Scan.aspx).

                    I serve the control as an object on the page, like so:

                    Code:
                    <object id="scanningObj" height="300px"
                    ...

                      Nathan,

                      Thanks for your swift and concise response. Am I right in thinking that, using the suggested method, I won't need to use any <%#DataBinder.E val... %> sections in my aspx files? I always did think using the <%..%> tags was a bit ASP classic!

                      Thanks again.

                        ASP.NET Repeater and Input Button issue

                        I have an issue with an ASP repeater which is seriously frustrating me.

                        In simple terms, I have an ASP repeater which is meant to display a list of items for a wedding list, including the name of the item, how many are available and a button to take the user to a "purchase" form where they select how many they wish to purchase. Once they're done, the page is reloaded and the new "number available" is displayed....

                          Hi, I'm surprised no-one's answered you in a whole year. You've probably worked something out or given up by now!

                          Anyway, I had a similar problem recently and thought I should share my solution. It may be the wrong way to go about it, but it worked.

                          Basically, I added a few extra columns to my dataset, having populated it with my data from the DB:

                          Code:
                          ds.Tables(0).Columns.Add("NewColumnName")

                            Logs for Component Services

                            Morning, I've had a look round for logs for Component Services and can't seem to find any. I've looked in the Windows Event Viewer, which is where I'd expect them to be, but there are none.

                            Are there any logs for Component Services, and if so where are they stored?

                            Thanks in advance,

                              Thanks Nistrum, that looks like it would work. In the end though, I've used a user-maintainable list of acceptable file types. This allows an administrator of the system to limit the types of file available to upload and thus gives the administrators much more control. If they wish to be able to add a new file type, all they gotta do is add it to the list.

                              I did find the location in the system registry where it would be possible...

                                Hehe, sorry for my slow response. I actually never figured it out and had to use an alternative method. The alternative method involved re-thinking what I was doing, but it was actually much neater in the end.

                                  Haha, I was really hoping you weren't going to say that.

                                  I guess when you call the HttpPostedFile. ContentType property, ASP.NET must have some kind of built-in MIME type lookup table, I was hoping there was another way to access this.

                                  I suppose there may be some way of fooling ASP.NET into using the HttpPostedFile class, as this would make everything much easier. I'm going to try adding my file into the HttpFileCollect ion...

                                    Afternoon,

                                    I've spent all morning trawling the net looking for an answer to this. In the end, I've had to resort to good old fashioned asking.

                                    How do you determine a file's MIME type using VB.NET?

                                    The problem is:
                                    - I have an ASP.NET web application
                                    - I can display a list of all files in a directory on the server (it's a "directory share" for a scanner)
