Web Forms :: Building A Form That Will Download Any File?
Jun 30, 2010
I have an idea of how to do what I have in mind, but I would prefer to ask for some advice just in case anyone can think of a better way.The idea is a simple application where administrators can upload any kind of file. Once the file is uploaded, they give out a username and password to a client, and the client will then access a private area where they will be able to view specific files available for them. ALL THIS IS DONE. My question is... because the browsers can process certain type of files (for instance a JPG or a PDF), they won't automatically prompt the client to save it on their computer, and they will open int he browser. I have solved this issue before by adding a few lines of code to the Response and modifying the content type, something like: Response.Clear(); Response.AddHeader("content-disposition", "attachment;filename=logo_large.gif"); Response.ContentType = "image/GIF"; Response.WriteFile(Server.MapPath(@"~/logo_large.gif")); Response.End();However, that would mean I'd need to change the content type for each file (JPG... GIF... PDF ... WORD FILE). So I'd need to find out the content type for each one, and dinamically change it. This way it would force the download for all files. Now... is there an easier way? Remember that I need to have many different type of files, if it was only JPGs for instance, it would be easy.

I 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 am storing one file per user on the server file system.
The path for each user is different and looks like this:
"~/resumes/<userName>/<userName>.xxx"

I am building the path to the users folder without a problem, however the file can be one of 3 types: doc, docx or pdf I need to know how finish my path for my filename. I have no way to know what files as been uploaded, it can be one of the afore mention 3 file types. How do I get the full fuilename to finish my path?

I have a web form that looks like a page for reading email, but it is used for reading messages from one user to another. Functionality, it needs to be able to download attachments that are send by other users. A user may sent up to five attachments (so five is the max per message) or none. If a user clicks the Icon pin, they should be able to see there attachments. So, my question is how do you do that? Any tutorials out there?
