Get All Nodes Below A Specific Point In XML?
Nov 22, 2009
I'm using the xmldocument class and I need to check in an RSS document if it includes the optional tags for a news item document. The two main ways that gets passed if via a <dc:creator> tag and an <author> tag below an item tag./rss/channel/item/?I'm new to this. I'd like to see if either of those tags are there, and if them and if not supplant it with something else.Right now in my code if I call /rss/channel/item/author and it's not there I get an error that dumps me. How can I test for it being there before I try something like:
Dim nodes As XPathNodeIterator = navigator.Select("/rss/channel/item/author")

I have two XmlDocuments that both have a namespace attribute specified. Both documents have the same structure, but contain different data. I can't seem to get a specific node tree from one document added to the end of the same node tree in a second document. Here is an example of my two documents:
Document #1:
<?xml version="1.0"?>
<rootnode xmlns="http://www.mynamespace.com/Service/2012-06-18">
[code]....
I certainly know this is wrong... I've tried serveral different approaches. This particular approach adds all <Item> nodes to the destination document, but it adds them to the very bottom of the document instead of after the last <Item>. how to add a specific node tree an XmlDocument to a specific position in another document? Again, there is a namespace involved and the <Item> nodes have nested nodes/elements under each one.
NOTE: The <Id> nodes have example data to show uniqueness only. I can never count on any kind of numbering. The order of each <Item> node is totally unimportant. I'm just assuming it will be easiest to add additional <Item> nodes after the last one in the destination document.

I have created a program in which I am supposed to add a stock to an existing table of stocks. I have this table of stocks stored in a file. The last line of the file is a ------- and the final stock is on the second to last line. HOw do I add a stock before the ----- and after the final stock??? I can't use append because that simply adds to the end and after the ---.

I've searched the forums for this, but I can't seem to find exactly what I am looking for. I have a form currently that allows me to open a photo in a picturebox. I would like to add functionality that would allow the user to click on a specific part of the photo and add a point overlaid on the photo. This point would be the graphical representation of comment that they will enter in a separate text box. I am stumped on how to even start to get this done.

I have a DataGridView control which is NOT bound any underlying data table. When the user selects a row (multi select is not enabled), I want them to be able to click an "insert" button to insert a row into the table below the selected row.I can insert a row at a specific location with the code below, and it will insert a new row at the location specified. My problem, is that I need to get the currently selected row and add 1 to it. However, the insert method below accepts an integer, and I cannot figure out how to get the currently selected row as an integer. I can only get it as a Row collection, which does not help. Can someone tell me how to get the currently selected row as an integer?[code]

I want to rotate a graphic at a point and I used the centerX and centerY to define the center of rotation.
Here is what I wrote:
Dim rotate_mirror as new RotateTransform(CSng(txtbx_rotate_by.text))
rotate_mirror.centerX = 5
rotate_mirror.centery = 55
blk_mirror.RenderTransform = rotate_mirror
blk_mirror is the graphic I want to rotate. Unfortunately, It does not work.

I hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right

I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

I have a treeview that is populated from a HDD folder collection. Its structure is similar to the following (however the structure is dynamic):
My Disk:
|
|--folder1(tag:folder)
| |--subfolder1(tag:folder)
[code]....
I call the sub as follows:
deleteNode(treeview1.Nodes(0).Nodes)
However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.

I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

I'm trying to calculate the direction between two points on a two-dimensional grid. Actually I want to determine if that vector is within a range of two values. Suppose the grid's origin is 0,0 at the upper left corner, and 0 degrees represents north. I have a point A on that grid. I want to know if a line from point A to point B on the grid is within a range of directions between 111.8 degrees (a little south of east) and 158.2 (a little east of south). Those are approximations; the 111.8 is 90 degrees plus the arctangent of 2/5, and 158.2 is 180 minus that value. I worked out a series of calculations worthy of a medieval astronomer, but I suspect there is a simpler way. I'm going to have to do this for a variety of other vectors, and I'd like to generalize
