I need some help figuring out how to parse an XML file in VB.net so I can find a particular node and write the contents into a database. Basically all the data in the XML node below needs to be read into an object.[code]I've had some success playing around with some Linq code, but I'm not able to figure out a way to traverse the sub nodes, so I can read them into an object.[code]

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 call the sub as follows:

However, the above is not working properly. It deletes only some nodes and not all the targeted nodes.

how to add treeview nodes and sub sub nodes using functions
View 1 RepliesI'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?
I'm running out of walls to bang my head against. Okay new windows form with a textbox, button and TreeView Populate the TreeView.nodes with the default nodes via properties
[Code]...
I want to click button1 and have the name of the childnode? Node3? placed in the textbox. Not via selection, I can do that. But via index or item number. The code I have is as follows
[Code]...
OK, so I have the code to add a Child Node to a selected node in ta TreeView. The thing is, even if I select a child node to "add" to, it adds the new node to the parent of the selected child node.
I know why it does that: TreeView1.Nodes(TreeView1.SelectedNode.Index).Nodes.Add() adds to the first node. So how do I progamatically add to the child node I have selected, not it's parent node. I can't figure out the logic on how to accomplish this.
NOTE: There can be an infinite amount of child nodes.
UPDATE: I just found out that if I have a child node selected, TreeView1.SelectedNode.Index returns -1 since there is nothing selected in that first level. I'd have to use TreeView1.Nodes(0).SelectedNode.Index to get the proper index for the ChildNode. *sigh*
I need to know what file attributes cant be added with another I know that Normal ontradicts all but Directory and NotIndexed. I also found out about Temporary cant be with encrypted or compressed and visa versa

View 1 RepliesI'm writing a class-library in VB.Net and one of the subs that are being called from the application which is using my library has more or less the following syntax:
Public Sub LoadDict(ByVal PhoneticType As String, ByVal strDict As String)
where PhoneticType can be phonSoundex, phonDoubleMetaphone or noPhonetic
I want to give the application-developer a possibility to select the PhoneticType from a list when writing the call of above sub (I think it's called attribute-arguments). This would make it easier for the developer since spelling-errors can be avoided and which will avoid errors when using the library. I think it's all about attributes but I haven't managed to get it to work despite trying.

View 3 RepliesI'm writing a VB program that will delete the contents of several folders, but it leaves the top folder. For example, after graduation and summer school, we delete the folders that belong to the (now) prior students.

We do this practice to manage our disk space.
