I have used the command:
For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?

Just started on vb.net
I have a combo box with "yes" and "no" with i select Yes i want the label2 to change the text to "yes" likewise with "no"
I've tried to code it in a logical way as possible but it just doesn't works except for the "wtf" so i think that overall my code is correct but the way i want to retrieve the selected item from combo box is wrong.

my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

Is it possible to compare 2 dataitems and then display the result depending on the 2 values using if eval at run time?I have a ListView with databound controls. 1 is RedemptionChoice and the 2 is CashBack.When 1 reads "0" and 2 reads > 0.00 the output should read AUTO I have read many comments online and most point to create a new function within code behind but have found it impossible to implement on my own.I tried this as a test on the actual page:
<%# If(Eval("CashBackRedemptionChoice").Equals("0") & Eval("[CashBack]").Equals("0.00"), "Auto Cashback"))%>
2 needs to be greater than 0.00 for AUTO to be displayed. Hence I know this would not work. Just trying to give an example of what I would like.

I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

Normally to add a item to a combobox I just do:
<option value="310">Willmington (310)</option>
But in a vb.net 2008 I am working a windows app to do the same thing, and for the life of me cannot figure out how.This is what I have currently.
While Reader.Read()
frmMain.cboType.Items.Add(Reader("TypeName").ToString)

In vb6, to add a combobox item, you simply say:
Combo1.AddItem
All easy enough. But how do you do that in VB .NET?

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.
[code]...
As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.
Here's my code:
I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.

I have a combobox that is bound to a dataset (via datatable and datatableAdapter). The combobox displays the current data in the table as it should.I have programmatically added the string "ADD..." to the list at the form.shown event:[code]when the user then click on (select) "ADD...", i open a new form to allow the user to add a new item to the list.The code i have behind the "ACCEPT" button on the new form stores the NEW value to the DATASET. I have verified this by previewing the data in the dataset.My problem is getting the combobox to reflect the changes to datatable to which it is bound.[code]

vs2005 -vbI have a combobox that gets its values from a call to the db. I have programatically added the list values for the box to match all the possible values that could be pulled from the DB. The user can update these values and update the db entry.I would like to be able to display any entries from the db, however, there is one value on the list that I don't want the user to be able to change the combobox's value to. I'm hoping there is some way to to 'hide' or '.visible=false' for just this one item when the list drops down so the user can't select that value.The box sits in a datagridview. I realize I could use the 'cellbeginedit' & 'cellendedit' events to prevent this action, but I consider that to be a last resort, as I think not showing it on dropdown is preferable code-wise.

I currently have this code to load a combobox. I also have a class to set the itemdata and text for each item. my problem is that when the form loads I have another query that selects a classid for a student. I want to compare the itemdata for each item in the combobox against the current classid for that pupil and then set the selectedindex of the combo where that classid is. How can I do it.
