Hey all, this post is going to sound a little strange, I hope I can explain things well enough. I am working on an application that uses the RSS 2.0 Framework (here on CodeProject) but I need to include the iTunes tags in the RSS file. I thought this would be simple enough but I am having problems with the serializing of the XML file. The iTunes tags are in the format <itunes:xxxxxx> but when the file is imported and serialized, the tags become <itune_0x003a_xxxxxx>, where 0x003A seems to be the hex representation of a colon character. Any ideas on things I can do to get around this?

It sounds like an issue when the xml file is serialized, the ":" is being treated as an illegal character. Unfortunately, I don't have any suggestions for getting around this problem.

I believe I may have found you an answer. In looking through this document:
http://www.vijaymukhi.com/documents/books/xsd/chap8.htm
it appears as though you need to use XmlSerializerNamespaces and pass that into the Serializer. It associates the namespace prefix with the tag and uses the colon as a separator.

Hello,
How can I check if there is a remainder in the division operation?
Thank you.

With the modulo operator: %
---
b { font-weight: normal; }

To write to Notepad from c# without creating a file I found the following code.
I need this because I dont have write permission on the client but I need to show
the extracted data in the Notepad.
Private Declare Ansi Function SendMessage Lib "user32.dll" Alias "SendMessageA" (ByVal hwnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As String) As Integer
Private Declare Function FindWindow Lib "user32.dll" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Integer
Private Declare Function FindWindowEx Lib "user32.dll" Alias "FindWindowExA" (ByVal hWnd1 As Int32, ByVal hWnd2 As Int32, ByVal lpsz1 As String, ByVal lpsz2 As String) As Int32
Private Const WM_SETTEXT As Integer = &HC
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim hwnd As Integer = FindWindow(vbNullString, "Untitled - Notepad") '/// assuming you have notepad open.
Dim x As Integer = FindWindowEx(hwnd, 0, "Edit", vbNullString)
Dim strText As String = "some text"
If Not x = 0 Then
SendMessage(x, WM_SETTEXT, 256, strText)
End If
End Sub
My question is: Is there a way to append text to notepad instead of WM_SETTEXT. I need this because sometimes the data to be extracted is huge and WM_SETTEXT may not suffice.

Hello!
I have an two-dimensional string array with values looking like this:
0 1
----
1 b
0 c
1 x
2 v
1 f
0 k
and so on. now I want to sort this array on the first column, so it would look like this:
0 1
----
0 c
0 k
1 b
1 x
1 f
2 v
I suppose I will have to do some manual sorting since I cant seem to find a sorting method for the array control.The only solution Ive come up with so far is making another array, looping through the first array and adding the row if column[0] = current value, but this solution would force me to loop for every new value in the column, which isnt very efficient.
Can anyone help me come up with a better solution?
/regards Magnus

there is a static Sort method on the Array class
|
|
|
|
|
Array class have Sort method but it sort one dimention array to make Array class sort two dimention array
you have to implement IComparer interface (Compare method)
and pass the implementation to Sort method
Sort Method[^]

hmm I think I wasnt very clear in my post. The array, or vector or whatever its called I have looks like this:
string [,] arAmount;<br />
<br />
arAmount= new string [coll.Count, 2];
and since I can't find the sort method u guys spoke of I guess it's not an actual array, but called something else.

Please modify the code code to handle 2D array.
public String[] GrowArray(String[] pOldArray, Int32 pNewSize)
{
Int32 counter = 0;
String[] newArray = null;
if(pOldArray != null)
{
if(pNewSize <= pOldArray.Length)
{
newArray = pOldArray;
}
else
{
newArray = new String[pNewSize];
foreach(String item in pOldArray)
{
newArray[counter] = item;
counter++;
}
}
}
//all the items of the old array have been copied to the new array and the new items are NULL
return newArray;
}
Hope this helps

Hi
I've been using XMLTextReader to be able to edit elements within an XML file easily (using the lineNumber and linePosition with a simple text handler), however I'm having a problem with navigating...
The object returned by readSubTree() is not of type XMLTextReader, so I can't use that and still get the line info out of it, and there doesn't appear to be a move/readToParent function that would take me back up a level in the XML. I could use readFollowing to move to the next element on the Parent's level but that seems like a bit of a bodge.
Can someone tell me if/how I can read back to the parent element?
Basically I want to be able to find the line info for a couple of child elements of a particular group of elements (if that makes any sense whatsoever )

XmlTextReader is forward only reader. You cannot read the values already read.
So what you can do is use a variable to store the parent.
Here is an example. I have not modified the code(just copy/paste)
while (xmlTextReader.Read())
{
switch (xmlTextReader.NodeType)
{
case XmlNodeType.Element:
string elementName = xmlTextReader.Name;
EntityBase entityBase = EntityHelper.CreateEntity(elementName);
while (xmlTextReader.MoveToNextAttribute())
{
if ( xmlTextReader.Name == "ID" )
{
entityBase.ValueList["ID"] = xmlTextReader.Value;
}
else if ( xmlTextReader.Name == "Name" )
{
TreeNode tempTreeNode = new TreeNode( xmlTextReader.Value.Trim());
entityBase.ValueList["Name"] = xmlTextReader.Value;
tempTreeNode.ImageIndex = ENTITYIMAGE;
if ( currentTreeNode == null )
{
tempTreeNode.Tag = entityBase;
currentTreeNode = tempTreeNode;
this.Nodes.Add(tempTreeNode);
}
else
{
tempTreeNode.Tag = entityBase;
currentTreeNode.Nodes.Add(tempTreeNode);
currentTreeNode = tempTreeNode;
}
//
//Add the dummy node
//
this.dummyNode = new TreeNode("dummy");
tempTreeNode.Nodes.Add(this.dummyNode);
break;
}
else
{
entityBase.ValueList[xmlTextReader.Name] = xmlTextReader.Value;
}
}
break;
case XmlNodeType.Text:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.CDATA:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.ProcessingInstruction:
Console.Write("");
break;
case XmlNodeType.Comment:
Console.Write("");
break;
case XmlNodeType.Document:
Console.Write("");
break;
case XmlNodeType.Whitespace:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.SignificantWhitespace:
Console.Write(xmlTextReader.Value);
break;
case XmlNodeType.EndElement:
if ( currentTreeNode != null )
{
if ( currentTreeNode.Parent == null )
{
currentTreeNode = null;
}
else
{
currentTreeNode = currentTreeNode.Parent;
}
}
break;
}
}
xmlTextReader.Close();
