View 1 RepliesI'm about to submit my pad file to multiple sharware sites but the pad file has to have a direct link to the download file and can't link to a download page which is what I would like to do, so I can track the traffic and get the downloader's email before allowing the download. I am running an ASP.NET site in VB. Is there a way to tell the web app to redirect to a specific aspx page when it receives a request for a specific file?

View 2 RepliesI am downloading file from database using the following code. This code downloads an excel file from the database which has a macro attached to it when it is opened. This macro reads file name of the excel file and uses it for its computation. Everthing works file if user saves the file on his harddisk and then open if but if he directly opens the file from the dialog(by hitting 'Open' button) then file name of the opened excel file comes out be the name of the webform that has the above code and this leads to error in the macro. Is there any option through which i can control the name of the file if user directly opens the file from dialog or the option to disable or remove 'Open' button form the dialog?

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.

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?

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.

Actually i am using JavaScript validation for Image or Word or Excel File & its working perfectly. My aim is making its full professional.
For Example When you use Photoshop and open any file you see only those extension which are applicable for Photoshop i.e. jpg, jpeg bmp, psd, png etc. You never see .doc, .xls or any other which are not open with Photoshop. This is i want to do, When i open for an Image it should show only Image Type file extension in file type By default its its showing All Files, As i use extension validation in JavaScript, it never accept .doc or .xls files in Image Type Validation but it will show. I want only that file type show for which i open.
