Shouldn't this be: <param name="url" value="<%= Video %>"/>

Sorry I mistyped that I am using <%=Video%> to view the video,but cant see on production server

Well then your wmv file is not where you are mapping to as I just tried your code and it worked. Using Server.MapPath("~/Videos/senegal.wmv") the sub-folder "Videos" must be located in the exact same folder as the web application.

It always works on local machine but not on productuion server.I have copied all the files in exactly same folders as I have on my local machine.The directory structure is

local machine

C:\myname\webapplication_name\Videos (here I have my video files)

on server


In this domainname, created a directory webapplication_name and created a subdirectory Videos

under webapplication_name.Copied video files in Videos folder

so the path for the video is folder on server should be

but server.mappath does not work with server.mappath("~/Videos/senegal.wmv")

Well Server.MapPath("~/Videos/senegal.wmv") is going to evaluate out to something like C:\Inetpub\wwwroot\web-application-name\Videos\senegal.wmv so if it is not, there is your problem.

I would add this line to your Page_Load handler in each place and see what the difference is:
     this.Response.Write("Server.MapPath: ->" + Server.MapPath("~/Videos/senegal.wmv") + "<-<br>");

Other than that we can't really help with something like that from here as we don't have access to the servers, whereas you do.


11/10/2008 6:29:33 PM

I was able to find out the path on the server where my video files are.

But even if use the absolute path to view my video I am unable to see it

ie instead of using


i used


but I cant see the video.Please help

How can we help? Have no idea what the problem is. Permissions maybe?



11/12/2008 2:35:05 PM

My hosting provider is saying that sometimes absolute path doesn't work with (which I doubt ?)

do you have any idea?

How could that be possible if it works using an absolute path on your pc? Same ASP.NET. We could try using a relative path: ResolveUrl("~/Videos/senegal.wmv") or ResolveClientUrl("~/Videos/senegal.wmv")

Or try this using an absolute URL. Maybe we'll get lucky:

string qualifiedFilename = "Videos/senegal.wmv";
Video = string.Format("{0}{1}/{2}",


11/12/2008 4:33:16 PM

Thank you .I will try to put this code on server and check

11/12/2008 4:55:43 PM

Tonnes of  thank you!!

It worked. I was struggling with  this issue for a long time.

11/12/2008 5:00:46 PM

Which one worked? The absolute URL or the relative filepath?



11/12/2008 5:02:21 PM

The absolute path worked.

Though I would like to know what does this code do here?

11/12/2008 5:17:09 PM

Produces an absolute URL such as rather than the qualified file path like D:\home\\webapplication_name\Videos\senegal.wmv

How can I use a linux server as a proxy between a DataSnap server/client
I have a DataSnap Server that is behind a NAT firewall. I also have many DataSnap clients that need to connect to that server. I want to provide a connection proxy to help those two computers connect and transfer data. The server will be authorized for this service ahead of time and I thought the best way would be to have a dedicated port on my Linux servers IP for each server needing my connection service. I have thought about L2TP type of VPN connection from the server to my linux server. It would be nice if I could create scripts/batch files on both ends to automate the install and make th...

automation server to client and client to server
I have to applications that need to communicate with each other. Is it practical for both of them to be servers and clients to each other? One of the applications will work primarily as a server and will launch the other application. The newly launched application needs to be able to send occasional information to the server to update information in the application that launched it. Also, if the user attempts to close the launched application it needs to tell the launcher application to close the appl ication that it launched. Does this sound practical? This is kind of like launching wo...
