Add Data Into A Multi-column List?

Jul 19, 2010

I need to add data into a multi-column list, manually, in codes. I am using VB Express 2008. Could someone please hint me on how to do this with the following controls:

The ListBox or the ListView
The Grid (I think it is the DataGridView)

Or anyother simple way of doing the stuff. All I want is simplicity.

DB/Reporting :: Use A Listview Or Similar As A Multi-column Combo Or List Box?

Sep 10, 2008

I have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.

I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.

Multi Column List Box Array Resets Before Adding Next Values

Mar 13, 2010

When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]

Have No Multi-column Combo Box

Oct 29, 2009

First, I don't fully understand why VBA can have a multi column combobox but full VB doesn't? What purpose does it serve to only have a drop down list of text strings? I know there is an index property, but what if the items in the drop down can't logically be associated with an index value?

Anyways, here is my problem. I have an enumeration value that I want to add to a combobox. I have the code to go through and add the text of each enumeration value to a combobox. This is fine for enumerations whose values progress in order from 0-whatever. However, I have some enumerations whose values are, for example[code]...

C# - Loop Through A Multi-column Listbox In WPF?

Oct 5, 2011

I have a listbox with two columns. Each listbox item contains a horizontal stacked panel which in turn contains textblocks.

The listbox is empty, with each listbox item being added by the end-user through a couple of textboxes placed elsewhere. The first column accepts strings, and the second column accepts only percentages.

(I have attached a relevant portion of the event sub where a user is adding new rows.)

Private Sub btnAddItem_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles btnAddSplit.Click
'...
Dim ListBoxItemName As New TextBlock

[Code]....

I would like to be able to check every time the above event is fired that the column of percentages does not exceed 100%. I have a couple of labels below the listbox itself where I would like to show the running total and the remainder.

My questions are:

1) How can I loop through the second column of percentages to show the running total and remainder?

2) Is there something more suitable than a ListBox that could make this easier?

Forms :: Multi Column Combobox (looking For Method)?

May 14, 2010

I'm using vs2008 with vb.net, and I have googled all around for a multi column combobox and I know there is not an easy way to do it in .net. However, this is my situation:I have a table in my database that only has around 4 or 5 entries, with the columns FirstName, LastName, Type. I need all of these columns for each of the 4 or 5 entries to be displayed in the combobox. I've been trying to think of simple ways to do it such as counting all the rows, selecting each cell in a loop and programmatically assigning them to the comboboxes, but I realized that the ID column for these entries have numbers that do not go chronologically. (I thought that if I counted the rows, the row number would correspond to the ID number and I could go about looping and assigning variables/concatenating them into the combobox, but this is not the case).

So I am just looking to see if anyone else has any ideas on what I can do to solve this? It's a pretty simple problem but I'm kinda out of any simple ideas.

VS 2010 Populate Multi-column Listview From File?

Jun 14, 2011

I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.

Compare The Value Of Two/multi Column Array And Add Into Listbox Without Duplication In Visual Basic?

May 2, 2012

I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):

ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal

[code]....

This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:

Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)

Read all the elements in the list and pass through ReadArrayString.Split the string using:

DataString.Split(New Char() {";"c})

Pass through

ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)

Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:

If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If

Now When you click TypeComboBox it will show drop down menu with following list only.

Animal
Bird
Fish

After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:

If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox

[code]....

I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.

One Selection At A Time From Multi List Boxes?

Aug 8, 2011

ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.

I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..

Multi-threading Processing - Processing A Large List Of Records And Inserting Them Into SQL Database One By One

Mar 18, 2011

I just learned some basics of multi threading in VB.net recently as I came across processing a large List of records and inserting them into SQL database one by one.

I have code look like this:

Dim autoLoad1 As New Thread(AddressOf AutoLoad)
autoLoad1.Start()

Itemlists is a global lists i retrieved from database, everything looks fine to me but when i run this program, I found that the threads are inserting one records 9 times into the database(I have 9 threads in total), which makes me think that maybe i need to specifically assign 1/9 of a list to each thread? Is there another way to do it which doesn't require the splitting of the list, if not , how do i split it then assign?

VS 2008 Multi-threding - Adding Multi-threading Facilities - Cross-thread Operation Not Valid

Feb 10, 2010

I'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.

When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.

It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?

How To Get Clean List Of All Column Names From MDB

I have a table in a Access Database that I'm loading into a VB.NET program and I want a way to get the name of each of the columns into a list of Strings.
