Or you could just get the cursor position after the user clicks.

Wouldn't the form's top-left corner have to be at 0,0 at all times for that to work properly? I mean, if the user moves the form around, the cursor position will vary every time he/she clicks.

No, no, no, no no. I meant the regular cursor -> |
Not the mouse cursor  . There should be a property for the text box, i think its either textBox.Cursor, textBox.Cursor.Position, or textBox.CursorPosition. Or something like that anyway.
Of course, that would give you the index of the current letter the cursor is next to, it would then be up to you to figure out what line that was, perhaps by looking for all newline symbols that occure before it (Environment.NewLine, or "\r\n")

Oh, I didn't know that 
Edit:
The Undefeated: You're looking for textBox1.Cursor.HotSpot.ToString();
or textBox1.Cursor.HotSpot.X and textBox1.Cursor.HotSpot.Y

Hmm, TextBox.Cursor seems to be what kind of mouse cursor is displayed when over the TextBox.
I think they call the "|" a caret...but there is only one member that is called something like that - ScrollToCaret().
|
|
|
|
|
Yes, TextBox.Cursor can also return what cursor is used for the textbox. But it can also
return the cursor's position on the textbox:
textBox1.Cursor.HotSpot.X;
textBox1.Cursor.HotSpot.Y;
textBox1.Cursor.HotSpot.ToString();

That's not the cursor position, that's the hotspot position.
If you want the cursor position, textBox1.PointToClient(Control.MousePosition).
If you want the caret position, use textBox1.SelectionStart (when nothing is selected, this property returns the caret position).

you should also consider the WordWrap property
in your solution..
why you want to do this ??

The function below should read an xml file and parse the elements and content, and I'm updating it to read the element content and the attribute values. So far the problem is with reading element content.
When the code uses method System.Xml.XmlReader.ReadElementContentAsString(), the code raises an exception (see Error).
However when the code using the above method is commented out the code is reading xml attributes.
On another note, any guidelines (for beginners) for validating XML and creating an XSD schema for validating it? My understanding is that this is the way suggested by w3c.
Less specifically, there are other ways of validating XML, including XmlSchemaValidator class, which would be most recommended?

Does the node which causes the error contain child elements? The MSDN documentation for the XmlReader.ReadElementContentString method states:
This method reads the start tag, the contents of the element, and moves the reader past the end element tag. It expands entities and ignores processing instructions and comments. The element can only contain simple content. That is, it cannot have child elements.
It also states that an XmlException exception will be raised when calling this method if the current element contains child elements.

you may use the string as an array ...
like arrayName[indexValue]...
and 2nd option is use a char pointer..and again you can manipulate is
as an array

The obvious choise would be to filter out the records in the SQL query, so that the don't end up in the result in the first place.
If you absolutely don't want to do that, you can use the StartsWith method of the string class.
Experience is the sum of all the mistakes you have done.

Yes? And what is your question? If you want to create a 2 dimensional array out of a 1 dimensional array, it can be done, but why?
