I use both zip (for solutions) and plain txt for other more simple things. That way I can do a simple windows-search on the filenames. A simple class: GetFileIcon (win32, shell, pinvoke).txt A solution with the basic send/recieve and conversion: TcpClient-TcpListener (network, socket).zip

When I started programming I created a lot of small code-samples to the the hang of the more complex things, and they are zipped with search-tags in their filenames. Now I'm doing the same for the abandoned projects thats worth saving.

As far as I remember it cant be done with basic audiovideoplayback. You might want to take a look at DirectShow instead, since you can define exactly what you want the player to do. You can start with the simple-playback sample from http://directshownet.sourceforge.net/[^] and add a DsDevice (aka soundcard output) to the graph (google how to).

Take a look at snarfle's DirectShow.NET - that'll make DS a whole lot easier to work with in C# http://directshownet.sourceforge.net/[^]

Thanks. I couldn't find InnerChanel on the svc, so I'll see if I can find another way around it.

Did you just read my offline code or my mind!? That's 99,9% the original code except 'svc.innerC...' and my out-commented 'Debug.' :) Now that's thougths that I like :thumbsup: It's getting a little late in the evening here, so I'll have to try it tomorrow morning. But it seems you like you know the "little thing" I need to change

You think like me :), that was som of the first things I tried - without success.

Have you tried setting the timeout of the client proxy (at run-time) to a comfortably high value?

Yes, tried that as the first thing. Changed timeout to 180 seconds (server responds in less than 4 seconds).

Ravi Bhavnani wrote:

Is there an uncaught exception occuring on the service end?

Not likely. The server always responds with, at least, a empty List within 4 seconds. (same for another test-method that simply takes a string and returns the same string).

Ravi Bhavnani wrote:

Is the returned list guaranteed to be not-null?

Yes. (at minimum it's a empty List of objects).

What you described is exactly whay I'm getting (a and b). Not entirely sure what you mean, but I create a new for each call

public static class
{
public static List<Assignment> Test()
{
MaintenanceService svc = new MaintenanceService();
List assignments = svc.GetAssignments().ToList;
svc.Dispose(); // <- this makes no difference
return assignments;
}
}

Ooops, didn't know that, 'cause That's the most common way in other forums

Not necessarily. I'm using a static Maintenance-class (where the previously posted code is called from a static method), because it has to make the same list of objects available throughout the entire app (Gui+Backend). Edit: svc.dispose don't make any difference after the code in opening-post. (Performance doesn't really matter - time does (my deadline is in approximately 48 hours).) Any ideas are welcome. I'm stuck (I'm probably thinking about this i a wrong way) ?

I'd guess (a wild guess) that the handle for A and C wouldn't change if it's being used when B is disconnected/reconnected. (maybe google how multiple USB TV-tuners keep using the ones that arent dis-/re-connected)

I see 1 posibility that spring to my mind. - MySql Connector is not installed on your Vista.

Not a code example, but you can disable CDROM/Remoable Driver/etc. in Windows' Group Policy (at least in Windows 7)

I Agree, but if you want to see how it can be done in c#, create a new WinfowdFormsApplication and take a look at it's Program.cs

I'm using Compact Framework 3.5 on a phone to contact a WCF-service, but I think my question is more related to this message board. When the code below is called a second time, from a class that is implemented as a singleton, it ends in som really unexpected errors. It works fine the first time it's run.

MaintenanceService svc = new MaintenanceService();
List<Assignment> assignments = svc.GetAssignments().ToList<Assignment>; // Fails here

The second time, it randomly throws 2 different exceptions (only one each time): - Sometimes it's a TimeOutException (System.Net.HttpWebRequest... - in VS-generated code). - And Other times it's a ObjectDisposedException (system.threading.timer for the WCF-TimeOut - in VS-generated code). If I use the same code from a Button_Click in a Form, it works every time, so I know it's not the service that are causing the error. I really need som help on this one?

Absolutely right. :thumbsup: (I incorrectly assumed that true would be 1 and not -1)

Thanks Geoff I didn't write the code (but that line is working) - maybe the compiler converts the boolean to a 0 or 1 in the background. I'll test it later

It's been a while since I've used VB and I need help with understanding the truePart in the second line.

Dim asciiBytes As Byte() = Encoding.ASCII.GetBytes("SomeAsciiData")

Dim nextchar As Integer = IIf(asciiBytes.Length > (i + 1), asciiBytes.Length > (i + 1), -1)

How does asciiBytes.Length > (i + 1) return an integer?

what to do if the user has cancelled the installation

Restore the old app-files if the user cancelled the update !

Iy shouldn't be nessecary to reinstall every time the xml changes. You could add a FileSystemWatcher to monitor changes in the xml-file and make the service load the updated xml-file.
