VS 2008 Altering How A Treeview Displays Data
Jun 15, 2009
I have an Active Directory browser written in vb.net 2008 that allows an end user to visually browse AD. Currently it displays the full DN for each child and what I want is to display just the name of the OU. Something tells me I would use the Tag() function but after playing with it, I just couldn't figure it out. All I removed was our internal domain name.
Would someone like to review what I have now and offer some ideas on what I would change to alter how the tree is viewed while retaining funuctionality?

I got a DataGrid Control that uses an Adodb.Recordset as a data source. I'd like to change the data type of the dodb.Recordset.Fields at run time. PS:I tried use the Type property but I got a message that it can't perform the operation when the object is open. Then I tried closing it with Close() but then it says the field is not available.

rewriting a class I use for saving Treeview data to a XML file for use of saving ListView data I can't really figure out the rewrite, I'm stucked, unfortunately Listviews seems to be a big problem for me in general.
Option Strict On
''' <summary>
''' The TreeViewDataAccess class allows the nodes within a TreeView to be

I have the following code, which reads data from xml file and displays it in the datagridview. It all works fine:
[Code]...
Instead of showing read data in datagridview, i'd want to read the data from xml file into one dimensional array: X(Impedances) Or is there a way to read value from this datatable into string variable without getting data from datagridview? The point is: i'd want to scan through all "Impedance" values (which are read from xml file) and compare with value y to catch the nearest value to y. How to do that?

I've created a class that inherits from CollectionBase that populates with a custom object type. I populate the custom collection and set it as the datasource for a ListBox control and set the appropriate DisplayMember value to one of the properties of my custom object.
While the binding behaviour is working great, I'm trying to polish up the UI because when the list of objects is somewhat long, there is a momentary flash where the ListBox displays the custom classname which is then replaced with the appropriate display data. I'd like to keep that initial flash of the ToString() method from appearing. I tried SuspendLayout() and ResumeLayout() on the control and the form, but neither keeps the flash from occuring.
What am I missing?

visual studio 2010 - Altering array values in VB.NET
View 8 Replies
Oct 19, 2011
I'm trying to validate a form to be filled out by the users, and when the required section isn't filled, I increment an
ErrorCount += 1
variable to show that error(s) have occurred inside the program, I then also set an
ErrorArray()
to whatever the corresponding field number is, now I have 0-12 (13 fields). What I have also done is titled the labels that are associated with all of these fields to correspond with the ErrorArray() value that might be set, such as.
PatLabel0
PatLabel1 etc.
What I am trying to do is loop through the array contents, depending on which ErrorArray() values have been set, to go and set the corresponding fontcolor property of that label to red, to show that these now need to be filled out. This is what I have, but Visual Studio doesn't allow me to use the iteration through the loop as a reference to changing properties. Can anyone point me in the right direction to trying to figure this out, or at least tell me what else I could do. Just seems doing 20 if....then....else.... statements with 2 - 3 lines in each of them is redundant when 1 function line could do the same job. This is what I have.
for i = 0 to UBound(ErrorArray(12))
if(ErrorArray(i) = "*")then
PatLabel(i).forecolor = color.red
[code]....
that is basically all im looking for initially, but I can't do it.

I have some xml that I read from an xml document, now I need to take that same xml and then change one field and then drop back to a file again. [Code] so then as you can see I tried to use a new open of the document from scratch and I get the same error. I read that its because I may have 2 imports that have the same method? I had 2 XML imports and made it only this, but still get the same error. [Code] how to fix my issue or a better way to read and change the one field I need to change?

I'm using a 2D array to store data in a grid and all the data is ones and zeros. By default, the array is all zeros. When I attempt to modify values in the array using variable(y)(x) = 1 where x and y are integers in range it changes the value to 1 in the entire column, not just a single cell.

Heres my issue which has been bugging me all day and i haven't been able to resolve.
I have a DGV on a form (frmResults) this is linked to a bindingsource of type InventoryItem (popInventory is a list(of InventoryItem) and popular is a list of another class object (StockItem). here's some code to explain better
first the declarations in my globals module
Public Module globals
Friend popInventory As New InventoryItem
Friend popStock As New StockItem
[Code].....
ok what this routine is doing is on the results form is 2 dgv's the first contains stock to keep, the 2nd one contains excess stock to sell. what i get however is all cells on both DGV's are the last item to be read from the popular list. the items are adding correctly (varified with a breakpoint and looking at variables at the time. the popInventory item is added to the relevent List.

basically I would like to create a Web Browser that displays the Content in it's screen. I started like this:
[Code]....
The 1st Struggle already is that hitting Enter after adding the Address does not display the content. I need to click on the Search Button. Additionally it would be nice if the Address is an IP Address that the last Part of the IP address could automatically be incremented and show the next Device in the Browser.

A form that will display the contents of a folder? I have my forms set up, I want the user to then click on a button that will load up a nw form which will contain a window that is a folder in one of my drives. There may be folders inside this main folder which the user can go into, but they can't go back frrom the original main folder and look at the other contents. First up, Is an explorer form the one I am looking for? Making one of those, it seems to be the right path but where to from there?
Another thing I need to be able to do is have the user double click on the files inside of the folder. When double clicked the folder still maintains its current state, as the files that will be clicked will do the work in the background. I have all the forms set up and linked together, I just need to know how to get this folder into a form..

The dropdown box displays all the items previously added to that column.
I want the user to be able to enter a new value OR just pick a previous value from the dropdown list. (This is when inserting a new row)
Problem:
Whenever I enter a value, it jumps around in my table like its on acid or something. Whenever I select a value from the list, it takes me to the line in which the value was originally entered.
How do I get it to do what I want.

iam currently working on my uni project and i have encountered a problem with valadation section.My system displays a message telling the user to input any fields that they have missed out on, listing the name of the field. However as these IF functions are in order the user must input the data in the order of how it is in the code. for example if the "consweight" is inputed and the calculate button is pressed, it thinks that all valadation above it has occured, when those fields are still empty.

I've made a browser project and beyond making it a default browser, I am having a problem with the Favorites feature TreeView control saving, loading and repopulating it with the users data. It's tough finding the correct code as there are so many variations of this control in various languages, but I did find sample code for loading and populating the TreeView with a text file using tabs to signify the node structure in VB.Net. (Most others I have found are VB6 or some other variation.)
