I'm trying to let the user download different documents where the data is stored in an SQL DB. In firefox, the filetype is correctly read, but not in IE. I'm trying to do this without having to set the ".pdf" or whatever extension the document has, because I haven't got that information. I only have the filetype.

I tried this tutorial [URL] .... It doesn't work with and vs 2010, and ajax control toolkit 4 ( I downloaded from link belowand vs 2010) and It doesn't work with ajaxcontroltollkit 3.5 I downloaded from same link.but when i put Your AjaxControlToolkit.dll in bin folder of my project it works fine.
I downloaded the same version of tolkit.dll as yours (3.0.30930.0) and I worked for me.
but I'd like to use version 4.
i have some problem on downloading file which file types are .doc, .docx and .pdf.
I have wrote the code for downloading when the button is click. the button can download these three types of file when click.
[Code]....
But, i have some weird condition. when i test in my local pc using the firefox, the downloading box popup with the file type detected. but when i upload the code files in live server and test the download button using firefox, the downloading popup but it cannot detect the file type.
therefore, i can proceed the download process using the firefox but i failed to open the files coz it dun have the file type.
I was referring muddasar's one of the article for the validation. Below is my code and i am trying to validate the file upload selected file format on the submit button. I have 4 upload control and fu1 is mandatory field and others are not mandatory fields. Though i need to validate all the four uploads if the files have been selected. My full sample code is below for easy testing,
<asp:FileUpload runat="server" ID="fu1" />
<asp:Label ID="lblMessage1" runat="server"></asp:Label>
<asp:FileUpload runat="server" ID="fu2" />
<asp:Label ID="lblMessage2" runat="server"></asp:Label>
[code]...
I am doing slight mistake on the return to the main function. if i test indvidual function it works fine. whereas if i include the 4 functions in one function with the return statement, it's not validating. goes to to the server.
I am not sure if I have found the right forum for this one.
the problem is:
I have a .licx file in my rootfolder.
I am getting the error:
Error 53 Unable to resolve type ' <add type="TabStrip" version="7.0" />' C:inetpubwwwrootCrop_ApplicationCrop_Applicationeo_web.licx 7 Crop_Application
,which I get for all the types that are in the xml file(i just gave one of them).
A friend told me that I have to add the type .licx in the MIME type in the IIS .
The problem is that I find the MIME type, I add the extension type .licx but I do not know the MIME type for .licx

Just trying to sum up either decimal or int values in a column in datatable. Currently getting a compile error, however think this is due to the incorrect generic constraint.

I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too.
Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive.
The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats.
For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window.
The problem:
As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem.

Is this problem easier than I think or is it as nasty as I am expecting?

View 3 Repliesi have mapped *.xyz extension to my own custom handler in asp.net and can run it on Windows asp.net.
How can I do the same thing on mono (Linux/Apache - ubuntu)?
I have this in my web.config:
<httpHandlers><add path="*.xyz" verb="*" type="MyCustomHandler,...">...
I also added similar things to mod_mono.conf and several other files but still I get http 404 The resource cannot be found.
I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension.
I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension.
First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests?
Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way?

I'm developing a website that has modular section. I would like it that when a new aspx (and aspx.cs) file is placed in a subdirectory of the application that I can ask the class some information...The idea is that when the file is placed in the directory a new menu item is added to the menu. To do that I need to "ask the class" for its name, icon, description, etc. Is there a way to determine the class that is defined in codebehind file and to instantiate an instance of it?I know I could look for and parse a config file for each plugin but I would rather not have to go that route.

I am opening and reading and I need to detect the encoding of the file that I am reading. There are different system users who will be using different encoding in their files so I have no control over this.
[Code]....
While the default encoding normally works there are special foreign language (non-English) characters that are not being read correctly, instead there are garbage characters in their place that I see "myString" above. Good foreign characters are visible in the file but the result in myString are unreadable garbage characters that are not valid.
I have researched this and it has been suggested to determine the encoding of the file and then use that encoding, but I have not been able to find out how to to do this.
so in a nutshell: how can I use vb.net to detect the encoding of an excel file?
I am using page handler using the code below:

Okay, maybe it's a bit pedantic, but do ASP.NET user controls HAVE to have an ascx extension?
My reason for wanting to know this is purely academic. I made the statement to someone that they usually have an ascx extension, but then I had the curious thought of if that was always true or not.
I need to set file extension precedence. I want the browser to show default.html before default.aspx. Is there a way to set this up in a web.config file?
