file.exists problem (1 Viewer)

[IanJ]

Hi all,

Just doing some very basic testing here as I'm new to C# and MP dev. I write mainly C++ for Arduino's.....anyways:-

To demonstrate my problem, no matter what I do it just can't see the file.

            if (File.Exists("C:/Program Files/Team MediaPortal/MediaPortal/test.txt"))
            {
                System.Media.SystemSounds.Question.Play();
            }

Any ideas? (be gentle with me!)

Ian.

Hi there,

I'm not a C# dev, but try/check:

Have you got a reference to System.IO (try putting "using System.IO;" at the beginning of your file)?
Have you tried changing the / to a \\ in the file path?

Hi,

Yes, I've tried both those & system.IO is in place. I've also tried removing the path completely (as I think the path I'm using is default anyway).

The following works, so I know that folder can be reached.

System.Diagnostics.Process.Start("C:/Program Files/Team MediaPortal/MediaPortal/scstoptvservice.cmd");
System.Threading.Thread.Sleep(2000);
System.Diagnostics.Process.Start("C:/Program Files/Team MediaPortal/MediaPortal/scstarttvservice.cmd");

What I am REALLY trying to do (not being a C# dev) is have 2 buttons on the screen and have a way of remembering which one was pressed last even if MP is restarted etc.......so I thought it would be easy to use file.exist as a way of detecting that. I don't really want to go near the database.

It might still be permissions problem of a sort. What OS? Do you have UAC on? Have you tried checking File.Exists(@"c:\test.txt") or File.Exists(@"c:\temp\test.txt")?

Hi there,

So you are trying to create a "token" to record which button was pressed even if the main the process/owner is restarted? ie: A flag file type arrangment (button1 creates a file called button1.flag)? Have you thought about writing to the registry instead?

Hi,

Yes thats exactly what I'm trying to do.

However, more progress..............so, I managed to modify the buttons to do what I wanted them to do, but the code I added for remembering the last pressed doesn't work because where I put it isn't being run.......!
I am basically using the demo here and thought I had identified a part of the code that was repeatedly being run, a main loop if you will......but obviously not!

So, can anyone tell me what part of the following code is looping when the page is accessed.....

Jings!, C# is different to C++ on Arduino's eh!.......I can't believe I am being stumped by such a small thing!!!

using System.Windows.Forms;

Would OnPageLoad and OnPageDispose be enough? To recall and to save. Not sure if the OnPageDispose is the right code, But you get my point.
