VS 2008 Create A Custom Comboboxitem?
May 6, 2010
I am trying to create a custom comboboxitem, yet I can't seem to figure out how to do it. I have done it for a listviewitem
Public Class CustomListViewItem
Inherits System.Windows.Forms.ListViewItem
End Class
but can not seem to get anything similar for the comboboxitem
Public Class ProjectComboBox
Inherits System.Windows.Forms.ComboBox?
End Class
I have found out that it is similar to a listbox item, but can not seem to inherit anything.

This question is a follow-up to one I asked and got answered here: How to display XPS document using a selected combobox item
I've created a WPF app using VB 2010. I set the comboboxitems via the XAML. However, I can't seem to figure out how to set the value of each item to a file path.
The objective is for a user to be able to select an item from a drop-down list, then that selection opens an XPS file in the DocumentViewer. The code below was provided to me by COMPETENT_TECH (thanks) to read and display the value of the selected comboboxitem in the DocumentViewer.
The path to the files I want opened is C:folderfile.xps
Private Sub Button4_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button4.Click

I have created a custom logonui.exe in VB.NET and I know how to make it replace the existing logonui.exe, but I am having trouble with the functions, such as shutdown, restart and log in. I don't need to get the list of users, because there is only one user account on the system and it is not password protected. I just need it to log in to the account when the user clicks a button and to be able to shutdown w

how to create my own custom property that is an object but that allows a string to be passed in to the property grid to configure it.For example, with a font type property you can type "Microsoft Sans Serif, 18pt" into the property grid and it will create the appropriate font structure and fill it.

In my program I've got several comboboxes that all have the same comboboxitems and when the user makes a selection in one of the comboboxes the selected comboboxitem gets disabled in the other comboboxes. (i.e. If the user has selected the comboboxitem with value 'a' in combobox #1 and selected the comboboxitem with value 'b' in combobox #2 then in remaining comboboxes both the comboboxitems with values 'a' and 'b' are disabled)

Well, the title pretty much says it all. I have a user control that is a a collection of six label controls. three are used as visual color indicators, and the other three are used as the corresponding value for each color indicator. (It's sort of like a legend key on a chart or map.) I have created a custom class to store the three values, and the associated methods to interact with the values. (I can probably use a structure instead of a class, but right now, I don't want to discuss that.) My problem, is that I want to show my user control inside a cell of a DataGridView. I've looked at the examples that create a MaskedTextBox DataGridViewCell, but I can't seem to get it to work. Here is what I have:

I want to create a custom control that has a cursor like a regular text box, I tried using a line and a timer that makes the line 'Blink', but that wasn't too reliable because I had to change the location and background in the timer... I guess I could do it, but I wanted to ask my question here.
Basically what I am doing is creating a custom control to allow inputs as in fractions, sub/superscripts, etc.... The TextBox Control doesn't support text in that many locations.

I have need for a customised form as the main page of my app, what I'm looking for is to create an amoebic shaped form, something like this. I realize that my 'window' will by nature need to be rectangular and that i will need it to have no titlebar and transparent edges, also i will need to have 'regions' on this form that will allow the form to be closed and turned into a standard rectangular form. I have no idea where to begin with doing this but I hope and presume it is possible with vb.net. The image I have used is for illustrative purposes only, i don't plan to do exactly this (my app is a database not a media player for one thing) If having it is a breach of copyright in this context I will remove it.

With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

I need two seperate lists, which every item is Integer, String, Bitmap - and one which every item is Integer, String String. However I don't know how to do this, or even where to look - I've googled for custom objects and custom object lists. What I'm trying to do is this.Custom Object1 is Integer, String, Bitmap Custom Object2 is Integer, String, String
In one thread I'll be adding items to List1(Of Object1), and processing them, and adding the results to List2(Of Object2), however I need to be able from other threads to look at the list and say only give me the items where Integer = (my thread ID), is this possible? Any help, or even links to information that would be relevant to this request would be helpful?

I'm creating an stock management application. At times I want to be able to search for a customer, location, or institution. I know how to do all of this, but what I really nee dot figure out is:How do I create/design a function that calls a form and has the user query information and then return that query's data, preferable datatable.Now, I've created the form that does all this and I have the dataTable but now I want to have a function that can call this "query form" and return that data.I was thinking I have to do something with multi-threading but maybe I'm just looking over something obvious. The best analogy of what I want to do is to create a custom dialog box, but obviously instead of returning a simple integer I'd be returning a dataTable.
