At least document everything public and protected, anything which can be seen by other code. Use all relevent XML tags. This includes, obviously, the <summary>. If your method has parameters, then use the <param> tags. If you return values, use the <returns> tag. If you explicitly throw an exception or let one slide that you want to make sure developers know is possible, use the <exception> tags. Basically, use any tags that are relevent to the to member. If you want to provide more information about something, then use the <remarks> and/or <example> tags.
For a great and free documentation compiler, see NDoc[^]. I've had the pleasure of working on it and I know this product is stable. Just look at the huge list of clients, including Microsoft. It can generate many formats like HTML Help 1 (ex: VS6 docs) and 2 (ex: VS7+ docs). It looks just like the current VS.NET / MSDN documentation as well.
For larger products in a corporate environment, you might consider abstracting all comments away to separate files. Then use the <include> tag to specify an XPath expression that imports the documentation. This seems to be what Microsoft does since many members - especially overloaded methods - share the same content for various sections.

Hand, Stop, and Error all use the big X.
Warning and Exclamation share a triangle with an exclamation point.
Asterisk and Information share a bubble with a lower case 'i'.
Does this provide the option for me to replace these icons with my own?

That is correct. It is a hang-over from the "olden days" ( Am I getting old?) when the enumerations had different names.

Not as far as I am aware.

If you want a better message box, create one. With the MessageBox in the FCL, what you see is what you get. This P/Invokes the native MessageBoxEx API, which is also limited.
Just build a Form derivative with a lot of the same functionality, perhaps exposing a public property for setting icons or stick the with single, overloaded method like MessageBox.Show where you can provide a custom icon. The Form derivative should be smart enough to resize itself when need and to allow for the customization of Buttons based on what's needed, as well as where to place them. It's really not as hard as it might sound, though, and many developers including myself have done this from time to time to provide a more feature-rich dialog.

This is a little vague. Can you be more specific?
I assume you mean outside of a LAN situation. And I am also assuming you don't want your existing windows to act as FTP servers either (which could have been an option as it is built into Windows). Further, I am assuming that you want the files to be transferred both ways - In other words Computer A can send files to and request files from Computer B, and also Computer B can send files to and request files from Computer A.

Sorry, I don't understand this. Do you mean what technology do you need to use in order to achieve your goal? Or what?

I think he means something like P2P networks without a central server. The Gnutella protocol is one example.

If you want to create a P2P network, you need to either define and implement the protocol yourself, implement an existing protocol, or use an existing protocol along with an existing library. Windows XP SP1 introduced a new P2P library that I know someone here was working on wrapping.
If you don't need an entire P2P network of clients and just want to communicate between two distinct clients, then you just need to use simple socket communications or .NET Remoting (a much more powerful technology using ubiquitous protocols like HTTP and SOAP).
For more information on .NET Remoting, see Accessing Objects in Other Application Domains using .NET Remoting[^], as well as http://www.ingorammer.com[^]. Pick up a good book, too. With power (extensibility) comes complixity.
For simple socket communications, see the System.Net.Sockets[^] namespace in the .NET Framework SDK, specifically the Socket class (for low-level comms), or the Tcp* and Udp* classes. Note that using this mechanism you're still left with defining at least a simple protocol whereby clients agree to so that they can communicate correctly.

How do I open a Collection Editor for a property in code? I know how to open if via the property editor. I want to force it open via code. Obviously it's doable, because VS.NET is doing it in the property editor.
Any ideas?

I think that is part of the Visual Studio IDE and not part of the .NET Framework.

Add the Editor attribute to the property, and set it to the type: System.ComponentModel.Design.CollectionEditor
I have a symbiotic relationship with my computer.

He's asking how you open it, not attribute your collection class/property with one.

VS.NET provides an implementation of the IWindowsFormsEditorService that UITypeEditors like the various collection editors use. It's not a simple question of just showing the form.
First, call TypeDescriptor.GetEditor with either the object or Type for which you want to get the collection editor. Cast that to a UITypeEditor. If not null, call UITypeEditor.EditValue passing an implementation of the IServiceProvider - which you must implement - along with the collection to edit.
In your implementation for the IServiceProvider, you must return an instance (could be the same instance) when the IWindowsFormsEditorService is requested, which you would also need to implement. This is what the specific UITypeEditor uses to display its collection editor form.

Does anyone have a code in c# for an application for a ticket agency that sells tickets in 3 auditoriums. The program should allow for the sell of specific available seats in the various price and location categories for the specific theater layout and performance and should be graphically displayable.
Thank You

This sounds like a homework question. You should attempt this yourself. However if you have any specific problems then you're more likely to get help.
BTW, no I've never done this sort of application, but is doesn't seem too difficult.
Do you have your data model sorted out yet?
Do you have your object model sorted out yet?

Hello,
I am using SystemParametersInfo from user32.dll to change the background on WinXP.
Now, whenever I change the background, the mouse moves from whatever its current position is to a spot near the bottom left corner of the screen. I could just save the cursors position before changing the background and move it back to its original position immediately after the background is changed, but is there a way to prevent it from moving in the first place? Does it have anything to do with SystemParametersInfo?
When I change the background thru windows by right-clicking on desktop and going to properties, the mouse gets moved to the center of the screen after the change.
Is this behaviour unavoidable?
Thanx for the help

Hey,
I am having a problem with an application which uses ADO.NET..
Here is the situation:
My application is composed of 2 forms : Form1 and Form2,
1- Form1 contains the Main method, and creates a new Form2()..
Form1()<br />
{<br />
...<br />
void SomeMethod(..)<br />
{<br />
Form2 f = new Form2(.., connectionObj, transactionObject..)<br />
f.Show();<br />
}<br />
...<br />
}
2- In Form2, I open the connection and start a TRANSACTION, like this:
...<br />
connectionObj.Open();<br />
transactionObj= conn.BeginTransaction();<br />
...<br />
this.Hide();
I don't commit the transaction in Form2, because I have to wait for another insertion request in Form1
3- When I move to Form1, I try to insert a new line in a certain table, with an SqlCommand, which I try to affect to the transaction, but it doesn't work, I get an error message.. It seems that the modifiation set to the transactionObj are not taken into consideration inside Form1, knowing that it was first declared in this form...
Any help please?!

Even after SqlConnection.BeginTransaction(), you have to set the SqlCommand.Transaction with the object returned by the former call.

Yes I do that everytime before I execute (.ExecuteNonQuery()) any command..the problem is when I return to Form1 (Remember that the transaction is set to a valuer in Form2), I create a new SqlCommand and I write :
sqlcommandObj.Transaction = transactionObj;
But I always get an error here :
sqlcommandObj.ExecuteNonQuery();

It would be helpful if you told us what the exception type and message were, perhaps even a stack trace. Would you just tell a doctor that you have a pain without specifying where?

for logging purposes, I need to be able to determine the thread ID of the currently executing thread.
I've discovered that I can pretty easily get the thread ID from the ProcessThread class. What I can't figure out is how to determine which ProcessThread corresponds to System.Threading.Thread.CurrentThread.
Any tips on how to get the ID that I'm looking for?
BTW, I've already tried using Thread.CurrentThread.GetHashCode(). While it seems to work (unique numbers), a comparison to the ProcessThread IDs in the app makes it perfectly clear that there's no direct correlation.

I used the following two:
System.Diagnositics.ProcessThread Id Property
AppDomain.GetCurrentThreadId()
The former is OS Thread ( so Process)
The latter is CLR Thread ( so AppDomain)
Is that what you are look for ? Any other ways ??

Thanks, James. The AppDomain is what I was looking for.
