Treeview Network PCs And Shared Directories With VB2010?
Sep 9, 2011I'm working on my first VB2010 project, having used VB6 up to now.In VB6, I used some library functions to implement a treeview of network PCs and their shared folders.
I've been searching, but I've not found a way to get this done with VB2010.
I have found scode to return a list of all the devices local to my network....close but not what I'm looking for.
Vb2010 Datagridview Auto Text?
Jan 30, 2011I would like for my datagridview to automatically fill in the column's next row with the previous entry + 1 letter. So say my datagrid is like this:
ID NextField
15-3A xxxxx
15-3B xxxxx
15-3C xxxxx
Everything is working fine if I type it in but would be nice if the user didn't have to type this each time and just have it fill in the next consecutive ID automatically when you press down to start a new row. Also i need it to work no matter what gets typed in... so if I make another ID 15-4A it will start filling in 15-4B etc. on each new row.
IDE :: Turn Off Auto-save In VB2010 Express?
Mar 24, 2011(pardon me for re-using someone else's wording - but it seems this question comes up in each NEW version of the IDE) Does anyone know how to disable VB autosave? I like to open a working solution/project, mess around with it, and if I cant get it working, I like to exit without saving so that the original working version is left.
But silly VB 2010 autosaves changes, therefore stuffing up, a once working solution/project. I can understand autosaving whilst working though a large solution, but I prefer to click save once I have accomplished a routine, in the solution/project.

Populate TreeView Via XML/DataSet
Feb 21, 2011This is a problem I have been trying to conquer for some time now and haven't managed to deal with. I've looked pretty hard on Google and so on, but most of what I find there is for populating a TreeView from a database. The closest I got was a bit of C# code for populating with a list of file paths. But unfortunately the result is individual roots & branches for each item.
What I'm working on is a message template tool where I'm trying to get the nodes in the treeview, which represents the templates, to populate from an XML file. I'm using DataSets for their simplicity of working with XML. Here's a basic example of the structure of the XML which is imported to the DataSet;
Code:
<?xml version="1.0" standalone="yes"?>
<Templates>
<Item>
[Code].....
So the path to each node will look like RootBranchName. I know this will no doubt require some recursion, but recursion is one thing I haven't fully grasped yet.

Feb 9, 2011I am trying to populate a TreeView in silverlight, but I am having some difficulties - it always appears empty.I found a good tutorial (here) on how to do it, I created a new project and copied the code as it appears, using C#, and it worked perfectly. I have now tried to incorporate it into my project (which uses VB), but It doesnt work. My VB code is as follows:

Use A Treeview XML File To Populate Buttons?
Jul 9, 2012The treeview system I am using is by Andy Bonner from the following Link, as advised I have created a new post.[url]...
Andy you were asking what it is I am trying to do so I will try explain it a little better. The treeview system you have created allows me to import / edit and save XML files based on the treeview structure that I create. What I now want to do is use the same XML files to populate buttons on a form.
So for example if I have 10 buttons on a form then on load it will look at the xml file and change the text of the buttons to whatever the main level of the treeview is.[code]...

View 1 RepliesTreeView Control - Populate From ArrayList Recursively
Jun 13, 2010I'm needing some help with populating a Treeview control using an ArrayList. The ArrayList contains a collection of a class called Task. The class properties contain the following:
1.) taskID (int)
2.) parentTaskID (int)
3.) taskLevel (int)
4.) subTasks (ArrayList)
5.) taskName (string)
Each Task instance can contain subtasks (which is a collection of the Task object), which can also contain subtasks, and so on. The base task starts at level 0. A subtask of the base task would be level 1. A subtask of a level 1 subtask would be a level 2, and so on.
-- The parentID would be the taskID of the parent Task. The parentID at the base task (level 0) would be -1.

VS 02/03 Auto-populate Textbox
May 14, 2010what I need to do is automatically (through a timer or similar method) look up a newly added record, and if it exists, have a number returned and populated to a specific textbox. I have the looking up the record and getting the field I want returned working fine, but I just cannot find any way to have it populate a textbox. Another small wrench in the works is that it's a web form. I think I'd be ok with a Windows form.The reason I need this is, the user will not be sure when this record has been added and it would work fine if they wanted to click a button until it is actually added to the table, retrieved and the number needed populates the textbox. However, the folks who gave me the spec prefer the user not to have to keep clicking a button for an undetermined amount of time. So, I've been trying to use a timer. I've tried everything I could think of to get it to populate the textbox. Even javascript didn't seem to work and neither did trying to a redirect back to itself. Everything is fine except for filling in the texbox.

The code is below. I would like to have these parent nodes populated on the form load and then (i think this is what i have read) to be quicker i would like to then load the childnodes once a parent node has been selected, as i don't want to load the whole database on form load or when the form is refreshed.
