Nothing needs to be added to your code, you use Find in the code trying to find one of your elements. Did you even read the documentation I linked to?

hi all,
i have a problem with custom controls. whenever i place a custom control on a form it doesn't paint correctly. infact it doesn't use my overriden OnPaint function and shows its type full name  as its text. the background is always white :/. i suspect it is dependent on some settings of a project, because when i just created new project and did exactly the same thing everything went fine... in runtime the OnPaint etc. is executed correctly. do you know what might be teh reason of such behaviour? thanks in advance

Hi, anyone can help me. I have xml like this :

<NmProject>Bussan - 2891000497 - Citrix</NmProject>
</Table>
<Table>
<KdProject>901559</KdProject>
<NmProject>Acer - 288 - LAN Switching </NmProject>
</Table>
<Table>
<KdProject>901560</KdProject>
<NmProject>Microsoft - 2881001136 - LAN Switching </NmProject>
</Table>
I want to delete this nodes
<Table>
<KdProject>901561</KdProject>
<NmProject>Bussan - 2891000497 - Citrix</NmProject>
</Table>
<Table>
<KdProject>901559</KdProject>
<NmProject>Acer - 288 - LAN Switching </NmProject>
</Table>
I use this code :
XmlDocument myXml = new XmlDocument();
myXml.Load(pathXML + "Project.XML");
XmlNodeList nodes = myXml.GetElementsByTagName("KdProject");
for (int i = 0; i < nodes.Count; i++)
{
DataTable dt = dsProject.Tables[0];
foreach (DataRow row in dt.Rows)
{
if (nodes[i].InnerText == Convert.ToString(row["KdProject"]))
{
XmlNode xmlnode = myXml.DocumentElement.ChildNodes.Item(i);
xmlnode.ParentNode.RemoveChild(xmlnode);
}
}
}
myXml.Save(pathXML + "Project.XML");
But I have error messages in
if (nodes[i].InnerText == Convert.ToString(row["KdProject"]))
that nodes[i].InnerText is null
Can anyone help me?
Thx

Sorry thats not valid XML, you cant have multiple root elements. Fix it, then try again.

This are completed xml, please help

A nested loop is a very bad idea, performance wise. Use XPAth to find the nodes you want.
Also, you shouldn't be iterating over a collection as you remove thigns from it. You should build a list of items to remove, then iterate over that, removing them from the original document.

I still confuse and stuck how I change my code?

As you've already been pointed out, itterating over every node is both inefficient and unnecessary.
I suggest you read up on XPath, which gives you a way of navigating to specific nodes using the SelectSingleNode and SelectNodes methods on an XmlNode.
The XPath you want looks for Table nodes with a specific content in the KdProject child. It looks like this for example: Table[KdProject = '901561']
So you can find the node you're after using (assuming xDoc is the XmlDocument instance):
XmlNode node= xDoc.DocumentElement.SelectSingleNode("Table[KdProject = '901561']")
and you can delete that node:
xDoc.DocumentElement.RemoveChild(node);
you should now be able to adapt your code to use this to repeat the deletion for every row in your data table.

I think the code, can remove just one row, how I can remove xml node based on KdProject tags
The original xml :
<?xml version="1.0" standalone="yes"?>
<NewDataSet>
<Table>
<KdProject>999999</KdProject>
<NmProject>Other Project</NmProject>
</Table>
<Table>
<KdProject>901561</KdProject>
<NmProject>Bussan - 2891000497 - Citrix</NmProject>
</Table>
<Table>
<KdProject>901559</KdProject>
<NmProject>Acer - 2881001136 - LAN Switching </NmProject>
</Table>
<Table>
<KdProject>901560</KdProject>
<NmProject>Microsoft - 2881001136 - LAN Switching </NmProject>
</Table>
</NewDataSet>
The result that I want :
<?xml version="1.0" standalone="yes"?>
<NewDataSet>
<Table>
<KdProject>999999</KdProject>
<NmProject>Other Project</NmProject>
</Table>
<Table>
<KdProject>901560</KdProject>
<NmProject>Microsoft - 2881001136 - LAN Switching </NmProject>
</Table>
</NewDataSet>
Please help,
Thx

Are you being serious??? If you can't work out how to do that from the code i provided then you need to go and buy a beginner book on programming and work through it.

How is defined PacketHeader?

Ethertype is in the byte[] s but I dont know how I can extract it.

I have this GUI project written in C# that loads pictures and graphical analog gauges. Also, it has a skin from SkinCrafter. When this GUI app is launched and starts to paint on the screen, the painting is not smooth in a way that the pictures and graphics appears in all direction, meaning, for instance, not just from top going down its bottom, and this happens with delays. Do you have an idea how can I make this appear smoothly, or one direction only.
Thanks a lot in advance.

You can show splash screen while your main form is being initialized. When initialization ends, close the splash screen. There are several good articles here on codeproject about developing splash screens.
