I want to poplate a checked list box based on a column from a datasource or standard listbox based on a selection from a combobox adding each item as I select it in the combo box.
Obviously populating direct from the data source would be best
I want to have an array with 2 columns - a list of applications in the first and the command to install them in the 2nd column. I want to display the array in a checked list box and based on selections run the command in the 2nd column I have done single column arrays but never tied them to commands

my form contains a checked list box [data coming from the database] a combo box [bind to a database table product] and a listview [was previously a listbox]

I want to display distinct items from a column in a checked list box then make a selection or selections and perform commands based on info from a second column in that database the database is a small Access 2010 database in the application directory right now I added the data source and items dont display even though I selected that source in the checked list box properties
Dataset = MyDataSet1
CheckedListBox = MyListBox1
I tried it with a combo box and it shows items but includes duplicates, did I setup the datasource wrong?
This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)

I have a textbox control with a button then underneath of it a have a checkboxlist control and another button. Basically what I want to do is when a User enters something on the textbox and then press the Add button the text they enter gets added to the checkbox list. This I was able to do with no problems, The problems comes when I try to remove the selected Items on the checkbox list. I have the following code.
Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim myPhoneNumber As String = txtPhoneNumber.Text
Dim myListOfPhoneNumbers As CheckBoxList = CType(chkPhoneNumbers, CheckBoxList)

I am working on making a Windows based application within Visual Basic 2008 Express that could potentially be used for a music school as a project. This application is connected and bound to a Microsoft Access database. Within this application I have a form for adding a new appointment reservation. This form has a combo box that the user can select the lesson type (eg. "I want a piano lesson"). Upon being changed, a list box would be populated with the names of all instructors that have that selection as either their primary or secondary talent.So, my database is bound, the query is written (correctly...i hope), and I don't know how to 1) select the table column that I want displayed in the list box and 2) actually display the query results within the list box. Is this making sense? Probably not, bu

I have multiple drop down lists on a page. They all contain list of countries. So in the background I am getting countries from database and caching them. I would like to populate those drop down lists from another thread. I am also using AJAX controls so I wanted that it all happens at the same time. And also after a user selects a country I want that towns from that country show to the user, and I want that getting towns happens also in another thread so that user can fill other controls while the list is not yet loaded.
I have read somewhere that I should give Page as a parameter to that thread and then find that drop down lists and populate them. But that is not working.
Here is a function that is called when another thread starts:
protected void GetCountries(object o)
{
if (Session["Countries"] == null)

I can't quite figure out how to populate the dang list with that code, am I doing something wrong?
I am building a form that will eventually list a group of functions on the left. If you drag a function onto the form, it will create a listbox and a label at the loction you dropped it to. If you drag a function into a listbox, it will add that function as a listbox item. I have this working kind of. The problem is that once I create a new listbox, I am no longer able to add items to the previous ones. Here is my code:

What i have created is a simple Indoor sports court allocation system for badminton. What i have created is 1) a Checked List box with names and checkboxes beside them - lets use one court for an example The court is represented by a richTextbox with three buttons underneath. button1 says (next Two) Button2 Says (next Four) and Button3 says Game Over. What i want to happen is when i click on button 1 it selects the checked names (two names - for next two) and removes them from the checkedboxlist and inserts them into the richtextbox when i click game over once they have finished it inserts the names back into the checkedlistbox with the other names. if i click button two (next four) i want it to do the same except it removes four from the checkedlisstbox and inserts them into the richtextlistbox and again when i click game overi want it to remove the entries and insert them back into the checkedlistbox list.Lastly once i click next four or next two i want to enable some progress indicators to time while the people are playing and when i click game over for the timer to reset to zero..
View 2 RepliesIt's been a while since I've used VB and I cant seem to remember how to clear/reset a checked list box. I can clear a check box and list box, but not the checked list box. While we're on the subject... what's the proper prefix for a checked list box? I've just been using clbListBox but I dont think that's correct.
View 3 RepliesI'm quite new to Visual Basic - using Visual Studio 2008 and can't seem to find a way to do the following:
I have a few tables in a SQL Server database and have used LINQ to SQL to create classes of those tables.
Here's a cut down example of what I'd like:listbox1 filled with table names - APS, SMPS, WCPC, CFLAPS
Then from the SelectedIndexChanged event, listbox2 should populate column headers of the selected table.
I have no issues getting data from the database, and can access all of these headers through the anonymous type objects created from a LINQ query (eg APS.ID, APS.count etc), but populating a listbox with these variable names rather than the data inside them seems rather elusive.
This is probably a cross platform coding question rather than VB specific, so if you have a solution in C# or whatever I'd be happy if you could let me know.
I'm having a bit of a problem with my if statement on my browser downloader checked list box at the moment.
This is happening: If the selected item is "Google Chrome" Then a textbox's text should be "Google Chrome".
I want it to be: If the checked item is "Google Chrome" Then a textbox's text should be "Google Chrome".
My current code for this is:
If boxBrowser.SelectedItem = "Google Chrome" Then
devbox.Text = "Chrome"
End If
I'm having a hard time figuring out why this is happening. When I check an item in the listbox it calls the sub ItemCheck for the listbox accordingly:
Code:
Private Sub chklbToDo_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles chklbToDo.ItemCheck
Dim iLoop As Integer
Dim iCheck As Boolean
[code]....
I've had to work with the delay of the check by reversing the boolean value caused by the check. But when I worked it into the program to delete the item that is checked, it deletes the selected/(un)checked item and THEN checks the item with the index. So in other words, if a user selects and checks an item in the listbox, and chooses to delete the item, it deletes the item and then checks the item that replaces it in the index (the following item).I don't understand why the checked value doesn't appear until after the sub ends.
I am trying to display contents of a remote share and based on selections in a checked list box copy only the selected folders to a local folder.
I can dsiplay the folders in teh checked list box fine, also can copy a folder no problem but now I want to do it based on the selections in the list box.

I wanted to see if I could have a list of six check boxes with names of a certain author that people have or have not read. When they are asked to check all that apply to them and then hit submit I want a label to display a message depending on the number of checks they made. So if they have 2 checks marked off then a message could say, "You do not read much of this authors books?" or 5 could say " You like this author, don't you?".
