Process.Start(MyResource)

[bhaughey]

Hi,
I'm having trouble opening a pdf (in a viewer) that I've added as a resource file.
I can open a file ok:
System.Diagnostics.Process.Start("MyPdf.pdf");

However trying to access it as a resource file I'm a bit stuck.

System.Diagnostics.Process.Start(TestApp.Propertie s.Resources.MyPdf);

The above line does not work as Process.Start() expects a string as an argument, whereas the resource is of type byte[]. Is there an alternative to Process.Start() that will open a file with it's default program? Or can I reference the resource file in a different way?

Any help is most appreciated,
Ben

Well you don't have a file (yet), you have a series of bytes (the byte[])
Try writing it to a temp file first and then opening that temp file?

Thankyou Plater! That did the trick.
Just one more question - would it be good practice to delete the temp file after the user has finished using it? If the answer is yes, how would you go about doing that? Is it possible to detect an event of that file closing?

Many thanks for your help

I would generally say yes, it would be good to delete the file, to avoid bloating the file system with temp files. But I wouldn't be sure how to detect if the file is no longer in use, other then to try to delete it.
