Is there any method or property of DataTable or DataRow to query the existence of a partucular column.
I am looking for some property like DataTable.ColumnExist.
Thank you.

I have never really dealt with network packets, and am writing a fun program to really dive into them. I am making an RPG Game using DirectX for graphics, input, and sound. So far so good. I have the game engine started and think all is ok there.
I now want to start the client/server side of the programming. The problem is I don't know how to have the client and server actually talk. Do I use SOAP and send object, I could use TCP packets... Which can handle more concurrent connections? It is to be a MMORPG...
So, if I use one technology over another, still how to I determine what action they are taking(walking, talking, attacking... ect.)
Basically, what technology should I look into, and can you explain why and very basically how they work.
Keep in mind I am not asking for code but for advice. Code samples would be cool though. If you know any articles, send them my way as well.
Thanks for any help!

I strongly encourage you to use WCF to implement the client/server bits of your app. It's easy to use, robust and very flexible. See this[^] CP section and this[^] MSDN tutorial.

I skimmed over it and I still don't see how I determine what they are trying to do(walk, talk, attack ect...)
Have you used this before, and what for?

You can use WCF to easily implement a solution for any of these scenarios:- Client (player) polls server when it needs to update its state of the world.
- Client (player) informs server when it performs an action (move, fire, etc.)
- Server broadcasts events to clients when the state of the universe changes.
I suspect you may want to use the 2nd and 3rd options, although you could use any combination. Btw, WCF is very efficient in handling multiple client sessions.
I currently use WCF at work.

Ok, I will look into. Thanks for the help.
Would it be ok if I contacted you at your email address on your signature if I have any problems?

Feel free to send me email, although I can't guarantee a swift response.  You're better off posting in this forum or in microsoft.public.dotnet.framework.

Hi guys.
How can we change TreeView's node icon? 
Do you know ?
|
|
|
|
|
Its a little wierd, but here it is:
this.treeView1.ImageList = new ImageList();
this.treeView1.ImageList.Images.Add("car", new Bitmap("C:\\Car.bmp"));
TreeNode myNode = new TreeNode("Car Node");
myNode.ImageKey = "CaR";
this.treeView1.Nodes.Add(myNode);
You can also set the ImageIndex of the node instead, so if you set this to 0 the node will use the first image in your image list, and if you set it to 1 it will use the second and so on.
Also, you will probably want to set the nodes SelectedImageKey unless if you want to use a different image when the node is selected.

Use the:
treeView1.SelectedImageKey
property.
FYI the image needs to be in the correct size because the treeview will NOT scale the image.

A train stops at a terminus, a bus stops at a terminus, on my desk I have a terminus.
(Well, I used to anyway.)

Thanks guys for your answers but What size the correct size is?

None in particular. What I meant was that if you would add a High resolution folder icon (4example) it would show huge in the threeview. According to the post before this one though, you can set auto scale, where a 21X21 image would show the same size as a 128X128. I don't what property this is though.

Hi all.
I want to know What the meaning of @ character is in Regular expression pattern? 
Like this :
Regex.Replace(str , @"pattern", "");
Thanks in advanced .
|

Hi,
The @ symbol is 'nothing' to do with the actual pattern... it is placed in front of a string to tell the compiler to ignore all escape characters (backslashes: \) contained within the string.
"\n" <- newline character
@"\n" <- \n

The following is a sample HTTP POST request and response
POST /Suppliers/WebServices/InsertLeads.asmx/InsertLead HTTP/1.1
Host: apps.abcsite.com
Content-Type: application/x-www-form-urlencoded
Content-Length: length
SupplierID=string&SupplierPassword=string&FirstName=string&LastName=string&EmailAddress=string&CoAppFirstName=string&CoAppLastName=string&Address=string&City=string&State=string&PostalCode=string&HomePhone=string&WorkPhone=string&WorkPhoneExt=string&CurrentEmployer=string&YearsThere=string&Income=string&BestCallTime=string&OriginalLeadDate=string&ExternalLeadID=string&IPAddress=string&ExtraFields=string
I want the below code to return me in HTML format instead of XML.
HTTP/1.1 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: length
<returnmessage xmlns="http://www.abcsite.com/">
<errorname>string
<errordescription>string
<leadid>string
<clientavailable>boolean
Here is one Instruction but I am asked to use this for C# , which I do not know :
This example assumes you have basic knowledge of how to use Visual Studio and the .NET Framework. In this example, the web reference to the ABCSite web service has already been added under a single folder called ABCSite. You would typically use this implementation when posting real time leads to our system via a form on one of your websites. This example is written in C#.
ABCSite.InsertLeads dpRealTimeWS = new ABCSite.InsertLeads();
ABCSite.returnMessage dpReturnWS = new ABCSite.returnMessage();
dpReturnWS = dpRealTimeWS.InsertLead(
Request.Form["txtSupplierID"],Request.Form["txtSupplierPassword"], Request.Form["txtFirstName"], Request.Form["txtLastName"],
Request.Form["txtCoAppFirstName"], Request.Form["txtCoAppLastName"],
Request.Form["txtCity"], Request.Form["txtState"], Request.Form["txtPostalCode"], Request.Form["txtHomePhone"], Request.Form["txtWorkPhone"], Request.Form["txtWorkPhoneExt"], Request.Form["txtBestCallTime"], Request.Form["txtEmailAddress"], Request.Form["txtOriginalLeadDate"],Request.Form["txtExternalLeadID"], Request.Form["txtIPAddress"], Request.Form["txtExtraFields"]);
lblWSResponse.Text = dpReturnWS.ErrorName + " " + dpReturnWS.ErrorDescription;

You need to ask this in the asp.net forum. I cannot stress highly enough the urgency of this advice.
