An interesting idea, but I don't think you'll get very far with it. The problem is the Microsoft (and Sony for that matter) sell consoles at a loss and make up the money by licensing games. If people could write and sell their own stuff for the xbox without giving Microsoft their cut then Microsoft would lose money.
From what I've heard Sony's latest PSP firmware upgrade did, amongst other things, lock out a lot of hacks that people had been using to write their own PSP apps. Sony doesn't get a cut from homebrewed apps so they don't want them on the PSP. Microsoft will no doubt take the same stance.

I'm completely with you 100%. I've been waiting to hear if they were going to do something in .NET so I could pursue a career in game dev. Where do I sign up?

Interesting but I'm not sure it will fly. Is there even a .Net Framework for the XP Media Center? (I honesty don't know either way) Does XBox360 even have the concept of "user" let alone principals?
Ultimately, I suspect the don't want to "open" any part of the XBox 360 due to lowering the bar for the evil specter of "piracy". If any Joe Programmer can write a C# program that can create a secure channel from the hard drive to the audio/video codec then what is the point of DMR or other security features they try to design into these things? Sure that would be great for us but rotten for MS.
So I guess I need to see exactly how they are going to open the platform up. If it is anything more pesky then what needs to be done for developing for PocketPC then forget it. If the API available to hobbiests is only a small subset where you can only create "toys" then forget it. Then the ubiquitous "someone" needs to implement a .Net Framework that is hopefully on par of the Compact version if not better *plus* documentation. All of this is some resource coming from somewhere...
In short, it would be nice but I don't know if it is even in MS's best interest let alone a good idea. Lower level programming on highly specialized hardware platforms is...how to put it...not as "fun" as a general computing platform.  I can't begin to think of what I would put on an XBox 360 since it is not a standard computing platform...

All the documentation and code examples I have seen for the WaitAny function states that this is a static function residing in the WaitHandle class. When I try to utilize this in my C# code I get the error message "System.Threading.WaitHandle does not contain a definition for WaitAny". (I am using ManualResetEvent and Threads within my application without any problems).
|
|
|
|
|
public static int WaitAny(WaitHandle[] waitHandles);
public static int WaitAny(WaitHandle[] waitHandles, int millisecondsTimeout, bool exitContext);
public static int WaitAny(WaitHandle[] waitHandles, TimeSpan timeout, bool exitContext);

I have this function:
[WebMethod]<br />
public string SetUserInfo(string AuthID, DataSet dg2)<br />
{<br />
if (AuthID=="********")<br />
{<br />
Oconn.Open();<br />
da.Update(dg2);<br />
Oconn.Close();<br />
return "it seems to have worked.";<br />
}<br />
else<br />
{<br />
return "Your Authentication Failed";<br />
}<br />
<br />
}<br />
and this is my da (dataAdapter) var:
public SqlDataAdapter da = new<br />
SqlDataAdapter();
but it keeps coming back with an error: "Update unable to find
TableMapping['Table'] or DataTable 'Table'"
http://digg.com

You should supply a DataTable named as Table in WebService function inputs(DataSet dg2)
|
|
|
|
|
public string SetUserInfo(string AuthID, DataSet dg2)
{
if (AuthID=="********")
{
Oconn.Open();
string connection = "server = localhost;database=urdatabase;uid=urid;pwd=urpswd";
string updatedata = "update urtable set AuthID = " + " '" + this.textbox1.text + "where AuthID = "********";
SqlConenction conn = new SqlConnection(connection );
SqlCommad cmdupdate = new SqlCommad(updatedata ,conn);
da.Fill(udataset,"urtable");
Oconn.Close();
}
else
{
return "Your Authentication Failed";
}
}
Maybe this helps u

Hi everybody.
I load an assembly into another AppDomain, not a default one. As there is no way to unload the assembly, I need to unload the domain. This is where the app hangs.
The problem is this assembly has references to one dll, currently not performing any work.
I tried this:
1. Setting the assembly to null,
2. Implementing a ClassFactory and returning an interface of the object, then removing it,
3. Making assembly to implement the IDisposable interface.
None of this works. All examples on the Net just shows how to create AppDomains, load assemblies and then unload the AppDomain. None of those show what happens if the assembly has referenced assemblies.
Thank you for your help.

I believe you also must unload the referenced assemblies. Is there a reason you cannot do this?
Picture a huge catholic cathedral. In it there's many people, including a gregorian monk choir. You know, those who sing beautifully. Then they start singing, in latin, as they always do: "Ad hominem..."

There is no way to unload the assembly at all. You can do this under Framework 2.0 but not under 1.1.
The only way is to unload the AppDomain, and it is clearly said that way at the Microsoft site.
The main assembly does not "realize" the AppDomain it is in is getting unloaded, so that it can do a clean up or something.
Also important to note is that no unmanaged code is accessed anywhere, so this is not the reason.
Thanks.

Right, I was just saying that you could load the referenced assembly in the same appdomain and then upload that appdomain.

Okay, he probably meant AppDomain.Unload, but this is not working.
I will try today to impement a WaitHandle to set a ManualResetEvent so that the assembly stop processing if the service singals that it should stop, so hopefully the unload will work.
The funny thing is that this area is much improvedin Framework 2.0, you can do anything with unloading single assemblies from the AppDomain.
Thanks.

I've tried loading assemblies that in turn refer to other assemblies in an AppDomain and it worked.

Have you implemented any finalizers in your code? It's very much possible that one of the finalizers hung and that resulted in the hang?

Can anyone help me with this:
I have a windows service(Already created)
That I want to read app.config,
and launch a DLL, (NOT an exe...)
This DLL, will also be called by a webpage at some point,
which is why we are using a dll, and not an exe...
(It is hard to shell an exe from a webpage inside the corp firewall)
Any suggestions? Comments?
Thanks,
Mike

What do you mean "launch a DLL"? Assemblies and shared objects contain executable stuff but without a context to run against its pointless. As far as the platform knows, it is just a collection of functions. By itself, there is no execution instructions or order let alone rhyme or reason so how can it ever be launched?
The purpose of a "service" is to often do non-"user interactive" tasks so why would you want the service to run anything external? Why not incorportate the functionality inside of the service itself?
I suspect you either misunderstand the purpose of the assembly/shared object or you need to provide more information.

Checkout the Process[^] class and it's Responding property along with it's GetProcesses method.

I have a openFileDialog which allows the user to specify the location of an application to open. He also selects times to open and close the application. Now all I need to know how to do is run the application. 
So ... does anyone know how to execute an external application that has the path to the executable specified?
Thanks!

System.Diagnostics.Process
here is an example of running PING with some arguments:
<code>
using System.Diagnostics;
public void RunPing()
{
Process p = new Process();
p.StartInfo.Arguments = "www.codeproject.com";
p.StartInfo.FileName = "ping.exe";
p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
p.Start();
p.WaitForExit(5000);
}

Hi
My network has a restriction and it doesnt allow me to download files from the internet for eq. .zip, .exe, .doc etc...... i believe they have restricted download for all possible file extensions. But i was amazed to see that it does allow me to download zip files from certain sites for eg. i am able to download the zip file from this loacation
https://www.microsoftelearning.com/ek_content/content/enus_085636/lsn_2/tpc_b/enus_085636_02b_4_procedures.zip[^]
but i am not able to download the zip file for this location
http://codeproject.com/miscctrl/gridctrl/gridctrl_demo225.zip[^]
Can anyone explain me why this is happening.
Regards

No offense to you, but you can probably get a better answer in a different forum than the c# forum. I'll do the best I can though:
Firewalls allow the ability to restrict/allow on a URL name basis. Whoever set up your network probably has codeproject.* allowed.

I did think abt that befor posting but i found too many people answering in this forum so i thought i will try my luck... Guess i am not that lucky.
