I have a listbox to display where user adds certain serials(let say A) to listbox or can remove serials from listbox. Now along with that serial "A" I want to store data like this "A,B,C" (from textbox) and pass it on the data to procedure but I don't want to show data to user like "A,B,C" , I just want to show "A".

i just started using vb2010 and i am working on a project wherein i want to display all the computer user accounts on a list box

I am using vb.net 2010. I have a datagridview whose data source is a data table. I dynamically add rows to the data table.
[Code]...
After adding the new row, m_table is correct. However, DVGCusClient not only adds this row, but also adds two additional blank rows at the bottom. I have no idea where these two blank rows come from. Why I use above code is as follows: Use a data grid view to display data. When a user clicks a row, another form is opened which allows user to search/input some data.When the user closes the form, all data is saved to a data table and shown on the data grid view.
How would you go toBrowse Forums Users , collect all the users by NAME, display them in a listbox and when clicked go to their profile.

This is what I'm trying to do: I have a listbox to display a list of costs that the user inputs. I want to use some kind of loop to add those numbers from the listbox sequentially, then display the total in a label.
How do I set up a loop (and what kind of loop is best) to pull the numbers and add them to a total? give an example of what the code might look like. I'm new to VB
I'm trying to create a for loop that will display the values (favorite programming languages) a user selects for a listbox.
So far I have this:
Dim selectedLanguages As String = ""
For intLoopIndex As Integer = 0 To languageListBox.Items.Count - 1
[code]....
So far, no matter how many items they select it will display a comma even if only one item is selected, example "C#,"However this is what I need it to do:
1. If the user selects one programming language than it should just printout the selected course with a period right after it. Example: C#.
2. If the user selects two languages it needs to have the text "and" between them followed by a period. Example: VisualBasic.Net and C#.
3. If the user selects three or more languages it needs to seperate them like this for example (again with a period at the end): VisualBasic.Net, C#, and Asp.net.
I have a Save() function as shown below;
Code:
Public Function Save() As Boolean
Dim valid As Boolean = True
Dim Message As String = String.Empty

What I want to do is when The toolbarbutton1 is clicked it checks for the
Save () - if txtprojend.Text = "" then it displays the message. So far, it does that but then it closes the form. I don't want it to close the form unless the user adds text in txtprojend, as it is a mandatory field.
basically i fot a form with 5 questions u could say and i got a toolstrip with a progrss bar wat i want to do is as each question is ansered in reality by the user i want the progress bar to go up.
min value is 0 max value is 100 as ther is 5 questions as each questiion is ansered the bar shoul go up by 20
so they anser Q1 it goes up to 20 they answr Q2 it goes up to 40 until they anser the last questyion and the bar is full
I am wanting to allow a user to enter a number and depending on what number is entered, it will allow that many entries. For example, if 5 is entered, the user has to enter 5 numbers. Those 5 numbers will then be added together.I 6 is entered, 6 total numbers will be added.I was trying to do this with a for next loop but I wasn't getting anywhere.

so listbox.Items. Add(StringRandom) but it should be displayed as A, B, C
not
A
B
C

View 7 RepliesThe program must display numbers 0 to the highest number entered into one of the textboxes which are even division of bigger number by smallest number.The program isn't quiet done, but I have the rest of it figured out.The problem is that for some reason the program won't change the label status text and display numbers in the listbox if number1 is negative and number2 is positive. But if number2 is -10 and number2 is 3 it works. Also it ignores any other If statements I made.

I've set my DisplayMember property of the listbox to the property I want yet when I add the objects to my listbox it "fails" and instead uses the .ToString of the entire object which doesn't return what I want.
[URL]
the DisplayMember only works if your listbox has a datasource. Well I'm not using a DataSource, like that guy I'm just using .Add. So how do I get DisplayMember to work without using a DataSource?Also I tried putting all of the objects (their simple item structures) into a List Of and then set that list as the DataSource to the ListBox and it actually added all of the objects to the listbox however the DisplayMember still didn't work and all I got where the results of Object.ToString().

View 5 RepliesI have a SQL table that contains 2 columns - report names and report category. In my application, I have one listbox that displays these report names. I have several categories for the different reports I have. Is there a way for me to display reports belonging to a particular category in one listbox and then have another listbox for another category? This way, depending on user login, I can selectively disable certain reports from certain users. I was hoping that this can be done during form load and not having to click a button to do any BindingSource.Filter method(). I have command buttons that let me search for a particular report based on user input of either the report name or category using the BindingSource.Filter method(). For my Listbox, I have the DataSource & DisplayMember properties set to Report_NamesBindingSource and ReportName. For one of my tests, I took out these two properties and wrote the ff code -
lstBxReportName.DataSource = "Report_NamesBindingSource"
lstBxReportName.Items.Add(Me.Report_NamesBindingSource.Filter = "ReportCategory = Cath")
lstBxReportName.DisplayMember = "ReportName"
hoping to set these properties programmatically and hopefully filter the dataset based on category but I get an error msg on the first line of code. -[QUOTE]Complex DataBinding accepts as a data source either an IList or an IListSource.[/QUOTE]Obviously, my code is wrong. When I comment out the first line and run it in debug, there is nothing in BindingSource.Filter when I hover my mouse pointer over the second line. So my listbox is empty when I run the program.The filter code below works fine for one listbox but I'd like to have different listboxes for report categories I have.- Me.Report_NamesBindingSource.Filter = "ReportCategory = 'Cath'"But how can I assign this type of filter to a particular listbox.
