Re: Inserting file header

So a class file is nothing more than a text file with a specific extension (e.g. cs). So you could use StreamReader/StreamWriter to add a header to each file.

It's not a bug, it's a feature!

You may use Form.FormClosing event. Use e.Cancel to cancel the closing process.
So, you have to check your values_changed 'flag', if is true, display the alert, and set e.Cancel = true.

Process Conversion Problem

Xmen Real 16-Feb-09 23:11

I have inherit Process class and added some very useful methods as I wrote earlier but now problem changed...

public static XProcess GetProcessByName(string name)
{
    Process[] tp = Process.GetProcessesByName(name);
    if (tp.Length == 0)
        return null;
    else
        return (XProcess)tp[0]; //Error : Unable to cast object of type 'System.Diagnostics.Process' to type 'XSystem.Diagnostics.XProcess'.
}

Well that is not possible since, XProcess inherits Process. You can cast XProcess-objects as Process-objects but not vice versa.

Maybe you should use composition and not inheritance here.

Well, your XProcess class probably have a constructor taking a Process as argument.If the answer is yes, then you may change

return (XProcess)tp[0];

into

return new XProcess(tp[0]);

ToolStrip query

Hi
I am trying to use a ToolStrip and it has me confused a bit.

I am adding the ToolStrip to a UserControl and I add a few ToolStripButtons to the ToolStrip. It looks ok, but when I add the UserControl to a Windows Form in the same project, the ToolStrip does not show any of the buttons. It shows the UserControl with the blue ToolStrip visible, but none of the buttons are displayed.

Any ideas?

Thanks

You should use BackgroundWorker Component added in the version 2.0!
this will solve your purpose! Smile | :)

Hi all,

I have a requirement of finding the depth of XML file.
For that i wrote an Recursive function but its not giving the correct value.

Please suggest me how to get the no'of levels in XML file or Depth of XML file.

Thanks in advance.

You could post your recursive function, this will be the best point to start.

int depth = 0;
XmlDocument doc = new XmlDocument("./XML/Sample.xml");
XmlNode node = doc.DocumentElement;
XmlNodeList nodeList = node.DocumentElement.ChildNodes;
if(nodeList.Count > 0)
{
depth ++;
foreach(XmlNode cnode in nodeList)
{
Recursive(cnode);
depth++;
}
}

public void Recursive(XmlNode node)
{
if(node.HasChildNodes)
{
XmlNodeList nodeList = node.ChildNodes;
if(nodeList.Count >0)
{
foreach(XmlNode cnode in nodeList)
{
Recursive(cnode);
depth++;
}

}
}
}

You are not counting the depth of the xml file, you are counting the nodes (not all, but nearly). What you have to do is sth similar to Depth-First-Search. You have to travel each path from root to leaf determining the length and check if this is bigger than all length of all paths in your tree.

Found an example in Java, doing exactly what you need:

http://www.sourcecodesworld.com/articles/java/java-data-structures/Determining_Tree_Depth.asp[^]

Take a look at the method _getdepth(). What the code does is to get the depth for each subtree and then compares these values, checking if it is bigger than all seen before.
