Can't load .PPTX after deployment in IIS 7

Question

0.00/5 (No votes)

See more:

I have an ASP.Net project. When I run it through VS 2010, I can load PPTX (PowerPoint) and PDF files. After I deployed the project in an IIS 7, the PPTX file can' be opened. The code for opening a .pptx is below:

C#

if (ext.ToUpper() == ".PPTX") {
   System.Diagnostics.Process.Start(sPath);  // sPath - address of the file
}

Besides, I cannot pop out Outlook for email for the project deployed in IIS.
How can this problem be solved? Thanks.

Is the IIS Server in your machine? or is it a server? If it is a server then you're trying to open a process on the server and not on the client.

Thanks for your post. This IIS server is on my machine. I got another failure in updating records stored in MS Access (can read/query) if depoloyed in he IIS.

And the IIS process have an user account capable of raise a process?

Not understand your statement. Could you explain? My pages should be open to anyone who can access the pages. Should I do some setup for the users? Thanks.

The IIS Server runs under an user account. For instance MACHINE\Network Service or other account. This account needs to have permission to raise a process (System.Diagnostics.Process.Start).

What's the error?

For loading .PPTX and opening Outlook, there is no error observed (I don't know how to debug the project loaded in IIS). For updating MS Access (works well if run in VS 2010 debugging), got such an error:
Operation must use an updateable query. An unhandled exception was generated during the execution of the current web request. Thanks if you have a clue on it.

Perhaps you need to open multiple questions. It is not clear at all where you are stuck.

Process.Start will only try to run on the server, which likely wont have office installed. Your better bet would bet to return the file for download either via the response object or by linking it through an iframe and letting the users machine/default prefs decide how to display it.

There may also be some control that you could put on your page that could load the file from the server so it appears more integrated but i've always had better luck just giving them a file and letting the user view the pptx or pdf however they're used to.

Tried to use Response for PDF and PPTX. Works fine for both in running VS 2010, but not for PPTX as deployed in IIS. My code is below:
WebClient client = new WebClient();
Byte[] buffer = client.DownloadData(sPath);
if (buffer != null) {
Response.ContentType = "application/pdf"; // or "application/pptx";
Response.AddHeader("content-length", buffer.Length.ToString());
Response.BinaryWrite(buffer);
}

i've found that some newer browsers have issues with getting files that way, you may also have to add the application/pdf and application/pptx mime type to IIS for your website. I've had to do that for m4v and mp4/mpg files. I've also had to flush the buffer when writing files(may not apply here its been a while since i worked on the download code)
