I think that's the simplest method

To Convert to C# from another Language you must Understand C#

Few companies that installed computers to reduce the employment of clerks have realized their expectations.... They now need more and more expensive clerks even though they call them "Developers" or "Programmers."

The Name of the node? Could that be what the Name[^] property is for?

If you are going to include XML in your post either manually escape the XML characters or check the "Ignore HTML tags in this message (good for code snippets)" box for the post (below the smilies and above the submit button)
If you are using .NET 3.5 there are new and better classes for querying XML.

If node a and des have attribute called "name" then you can get the value of that attribute by following
foreach (XmlNode node in List)
{
int i = int.Parse(node["a"].Attributes["name"].Value;);
des[i]= node["des"].Attributes["name"].Value;
}

Hi
I want to do a project where I need to calculate the intersection of the two cubes but I don't now how i can calculate the volume of this intersection. This is the project
Create a small web application that allows a user to enter the dimensions and coordinates of two cubic objects in a 3-dimensional space. Once the information has been entered, the web application should calculate if the two cubes intersect, and if so, what the volume of the shared space is.
Note, the coordinates specify the CENTER of the cube!
Sample Data:
Cube A: Size = 5m x = 10m
y = 10m
z = 0
Cube B: Size = 2m x = 9m
y = 9m
z = 1m
Answer: Do the cubes intersect? What is the volume of the shared space?

Guys,
I am trying to save the hidden panel contents to an image using GDI+.
I do not want to resize the panel to show all the contents and then save it.
I would like to keep the panel at the default size and save all the hidden contents without scrolling.
Thx.

|
|
|
|
Image image = this.panel1.BackgroundImage;
image.Save("1.jpg");

Thx for the response.
The contents on my panel are custom drawn items. I would to save everything (hidden items as well) to a image file without scrolling or resizing the panel.
|

Well, about this, I do not know how to save the graphic objects into a file directly. However, you can save a image through Bitmap. Such as:
Bitmap bitmap = new Bitmap(400,400);
Graphics g = Graphics.FromImage(bitmap);
Pen pen = new Pen(Color.Black);
g.DrawEllipse(pen, new Rectangle(10, 10, 200, 200));
bitmap.Save("test.jpg");
Hope this will help you~

Hi,
I have Form app that includes a DataGridView control (bound to DataTable). The user can sort the columns by clicking the column headers.
If the user has clicked the Date header (to sort the column), the code below fails to update all rows in the DataGridView (and Database). The list is fairly large (few hundred), so I can only guess that when a certain number of rows are updated (via - row.Cells["Col_ItemAddedDate"].Value = newItemDate;) a resort occurs that mucks up the foreach loop? If I don't update the DGV cell, the loop works fine to update database.
foreach (DataGridViewRow row in dataGridView1.SelectedRows)
{
OleDbCommand myCommand = new OleDbCommand("UPDATE Products SET ItemAddedDate=? WHERE ItemID=?", myConnection);
myCommand.Parameters.Add("@ItemAddedDate", OleDbType.Date).Value = newItemDate;
myCommand.Parameters.Add("@ItemID", OleDbType.BigInt).Value = row.Cells["ItemID"].Value;
// execute the command
myCommand.ExecuteNonQuery();
// THIS CODE CAUSES THE LOOP TO FAIL (if the Col_ItemAddedDate column header is clicked to sort)
// Some of the rows are updated, but some do not (both Database UPDATE and the DGV cell update will fail)
row.Cells["Col_ItemAddedDate"].Value = newItemDate;
}

I'm using TableAdapter.Update() to insert data to database. Is there a way to update ID columne value of the inserted row in the DataSet, hopefully without select @@identity/scope_identity() method?

Hello,
Last time I asked how can I create an sql server alias programatically,
and Mika gave me a great link which works great.
This is what I am doing:
ManagementScope scope = new ManagementScope(@"\\" + client + @"\root\Microsoft\SqlServer\ComputerManagement");
ManagementClass clientAlias = new ManagementClass(scope, new ManagementPath("SqlServerAlias"), null);
clientAlias.Get();
ManagementObject alias = clientAlias.CreateInstance();
alias.SetPropertyValue("AliasName", aliasName);
alias.SetPropertyValue("ServerName", server);
alias.SetPropertyValue("ProtocolName", prot);
alias.SetPropertyValue("ConnectionString", conn);
alias.Put();
If the client is my local computer - works greate.
If it is a remote connection, I keep getting access denided.
What priviliges do I need ?
I tried using ConnectionOptions with user that has administrator priviligies on the client - didn't work.
Thanks
Calanit

Does your SQL Server permit remote connections? Is the user defined in the connection string permitted access. If you are using a trusted connection, is it a domain user?

Thanks - checked all the permisions, was missing domain user connection string permision.

I think you need admin privileges on the target computer (not sure though). Did you have look at this: http://msdn.microsoft.com/en-us/library/system.management.managementscope.aspx[^].
One thing that could be the problem is that if you use a different username/password than your current session, do you spoecify also the domain (either the real domain if youre using domain admin or the computername itself if your useing the computer local admin).
From the link:
<code>ConnectionOptions options = new ConnectionOptions();</code>
