AFAIK, there's no way to prevent access to Task Manager. It's a separate application running in it's own process space, so there will always be a way to get to it. Similarly, you can't prevent people getting access to other applications - it would be a very poor design if you could because this would interfere with the way people want to work. In other words, if you could do this there would be nothing to stop a virus writer from ruining your program.

I agree with Pete, this is generally a bad idea. If you really need it, check out SetForegroundWindow and MainWindowHandle API functions at www.pinvoke.net
I'm pretty sure you can't deal with taskmanager though - for obvious reasons.

I Execute "select * from dbo.Employees for xml auto" in sqlServer.
C# Develope:
SqlConnection sqlCon = new SqlConnection(@"server=JASON-FREE\SQL2K;database=Northwind;uid=sa;pwd=**");
SqlCommand sqlComm = new SqlCommand();
sqlComm.CommandType = CommandType.Text;
sqlComm.CommandText = "SELECT * FROM Employees for xml auto";
sqlComm.Connection = sqlCon;
sqlCon.Open();
//then how to write?
XmlReader xr = sqlComm.ExecuteXmlReader();//Is right?

You can fill a DataSet and use WriteXML() method.

DataGridViewCheckBoxColumn checkboxColumn = new DataGridViewCheckBoxColumn();

Hello Friends,
I want to create the multilevel tree view in windows application using c#2.0.
I want to add the nodes in tree view form .
If one node has its child then that should be added under that parent node.
Which I am not able to do.

hi,
Thanks for your rply.
Actually I added the nodes in TV but not able to add child node under its parent node.
I am not able to find its parent node. To find I am using this :
treeNode findNode = new treeNode();
findNode = myNode.Nodes.Find(objReader["catId"].ToString(), true);
but giving the following error :
Cannot implicitly convert type 'System.Windows.Forms.TreeNode[]' to 'System.Windows.Forms.TreeNode'
Regards,

Find() return type is TreeNode[] so how can you assign TreeNode[] to TreeNode
The code will be :
TreeNode[] TN = myNode.Nodes.Find(objReader["catId"].ToString(), true);
to add node as child node, here is a sample
TV.Nodes[<Index Of Parent Node>].Nodes.Add()
hope this will help

Thanks for this.
The error does't come again.
But not sure whether it finds the search node in treeNode.
Actually I m using the following code for populating the tree.
But not able to do as all the nodes are comming on same level.
If any node has child then its chils will be added under that.Not successed in doing this.
private void createTreeView2(string id)
{
TreeNode myNode = new TreeNode();
TreeNode findNode = new TreeNode();
string connStr = connString;
SqlConnection myConn = new SqlConnection(connStr);
string sqlQuery = "SELECT * from article where parentId='" + id + "'";
myConn.Open();
SqlCommand myCommand = new SqlCommand(sqlQuery, myConn);
SqlDataReader objReader = myCommand.ExecuteReader();
while (objReader.Read())
{
myNode = new TreeNode();
myNode = myNode.Nodes.Add(objReader["articleId"].ToString(), objReader["articleName"].ToString());
TreeNode[] findNode = myNode.Nodes.Find(objReader["articleId"].ToString(), true);
tvArticle.Nodes.Add(myNode);
if (isChild(objReader["articleId"].ToString()))
{
createTreeView2(objReader["articleId"].ToString());
}
}
}
This is my requirement.

-Washing
-washingMachine
-drymachine
Here are 4 levels but this could be any number of levels. What we want is to display this in tree view (+, -).
Following is the sample database.
articleID(auto incrementID) parentArticleId articleName status
1 0 Electronics A
2 0 Washing A
3 1 TV A
4 1 Stereo A
5 2 washingMachine A
6 2 dryMaching A
7 3 Screen A
8 7 58 cm A
9 7 62 Cm A
10 7 68cm A
11 4 With Fm A
This is the explanation of the requirement.

here is simple code :
if (objReader["parentArticleId"] == 0)
TV.Nodes.Add(objReader["articleId"].ToString(), objReader["articleName"].ToString());
else
{
TreeNode[] findNode = TV.Nodes.Find(objReader["articleId"].ToString(), true);
findNode[0].Nodes.Add(objReader["articleId"].ToString(), objReader["articleName"].ToString());
}
hope it will work

Hi,
I wanted to find out the user name of the application.
Example: user name: rozhanin
I looked up on the net and i find answers which return the login name (dz2344).
I used the Active Directory and was able to find out the name (rozhanin), but this does not work on some computers. 
Is there any other method to find the user name.
your help will be greatly appreciated.
Thanks!!

Hi Dipak,
Like i told you by using SystemInformation.UserName gives me the login id(example: dz1234) on the network. I wanted to find the name of the person with this login id (example: rozhanin).
I could achieve this by using InterOp.ActiveDs.dll, but this does not work on some computers. Is there any other method to find the Name of the user given the login id??
Thanks for your reply ,
rozhanin.

Hi all,
I already convert a C++ project to C# project. It's fine and working ok.
On C++ I use DWORD data type. But in C# for that I used just a int value. Is that ok. Is there compatible data type which I can use for my project.
Thanks. 
I appreciate your help all the time...

Are you having an issue, or are you just worried in general ? long is bigger than int in C#.
