Where The ListBox Displays The Custom Classname Which Is Then Replaced With The Appropriate Display Data.
Apr 21, 2009
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?

Is it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]
I tried doing the above code but instead of displaying the listbox text the message box just returned false.

I have an Address Book project with a listbox. The listbox is bound to the database via the little arrow pop-up box in the corner of the listbox. I have the DisplayMember set to FirstName, and obviously only display the First Name of the contact in the ListBox. Is there an easy way to change it so that it displays the First and Last names? I can't change the binding because I need it to get the ID of the record selected.Here's the basis of my code...
Private Sub MainForm_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load

Dim pt as new point(8,9)
A spy on pt will show "{X = 8 Y = 9}"So i want :
Dim cust1 as cust_type1
to display me something differente than "{namespace.cust_type1}"

Pretty basic problem here. Nothing shows up in my listbox at runtime when I add these labels. Dim lblPerson As Label = New Label() lblPerson.Name = "Person" & Master.People.Count + 1 I even tried overriding the ToString() function of the label class as to return Me.Name:

I just started learning VB.NET about a moth ago (I have been taking classes, so its been about 5 days worth of classes) and I decided to work on this project idea I had. Essentially, it's a database to keep track of anime and manga that I, or whoever else uses it, have watched/read.[code]...
However, now I want to make it so that when one selects a specific title in the list box, it will show the data in the tags below the <series> tag that matches the item selected in a label. One thing I just thought of is than since the list box gets populated in the order that the series are in, it could be easier to go in order from first item equaling the first <series> and so on.

My aim is to choose a value from Listbox1 and on Listbox2 I would like to display the corresponding value from a table in my database. I mean, when I select Product A from Listbox1 (which is getting its values from row "Model" in my database table), I should see its price on Listbox2 which is available in the "Price" row of the same table (and also manipulate this price in different places for calculation etc.) . I am not sure if the best way is using "databinding.filter".
Here is the code I have but I cannot making it work:
Dim dtCOP As New AmetailorDataSet.COPDataTable
Dim adapterCOP As New AmetailorDataSetTableAdapters.COPTableAdapter
adapterCOP.Fill(dtCOP)
[code]...
A small note: my aim was using a Richtextbox instead of Listbox but I am told that Richtextbox is not suitable for using with datasources.

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 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?

what I could use to display some help for a function (or subroutine) in the popup that appears when entering said function in the VS2005 IDE when using VB.NET. I discovered later that you could use the XML code documentation to write the description. Just type 3 single quotes (''') on a new line directly above the function you want to document and press return. The IDE creates a comment template. Just enter your description text within <para></para> in the <summary> section and it will show up when the intellisense dropdown is displayed for your function.

I am in the process of converting vb6 assemblies to VB.NET.I am trying to overcome a particular design challenge.I have a vb6 EXE sitting on a Terminal Server which is shared between multiple customers.Each customer has customizations in the form of overrides to this EXE in custom business logic contained within DLL's.We know what DLL to look at based on a setting in the database.We use the CreateObject ("CustomerDLLName.CustomerClass") method to create late bound objects.If the object is "not nothing", we check for override code.For example, if my base EXE has a sub called PrintForm, based on the logged in user I may use the base sub within the executable, or I may need to use the sub in a custom DLL:
Dim oCustom as Object<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
Dim strSetting as String<o:p></o:p>
strSetting = "Customer1DLL.Class1"[code].....
I am struggling to come up with a comparable if not better way to do the same thing in .NET. I want to continue sharing the base EXE so I can't just have separate EXE's and DLL's in separate folders.They all need to live in the same c:/Program Files/[Application Name] root directory so I can take advantage of the Terminal Server's shared application memory.
