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]

My program has an access database with a table called "Contacts". This table stores many values. I have a seperate table that stores surveys. Each contact should have a column for every survey, indicating whether or not the survey has been completed. However, this means I need to add columns to the database while the program is running. I tried the following code, which runs WITHOUT errors, but does not seem to actually add the column.
contactsDataAdapter = New OleDb.OleDbDataAdapter("SELECT * FROM Contacts", frmAdmin.con)
contactsCommandBuilder = New OleDb.OleDbCommandBuilder(contactsDataAdapter)
dtContacts.Clear()

View 7 RepliesI'm working on VB .NET 2008.
Target: Bind dynamic datasource in a cell of a Windows.Forms.DataGridView depending on the selection in previous column. The grid must have 7 columns. If the selection on comboboxcolumn 2 or 4 is done, the datasource of comboboxcolumns 3 and 5 mus change using a query with previous selection as parameter.
In a first try to develop this functionality i've tried to use Telerik.WinControls.UI.RadGridView control. I've created a customized celltemplate with a combobox in order to have different datasource for each cell on the same column. All worked fine but seems to be some kind of bug in RadGridView, because when the combobox is presenting the list, after selection the list continued showing, doesn't dissapears as expected.
Ok, after several days of fight with RadGridView, I give up, and I tried to use same strategy but using Windows.Forms.DataGridView. I've created two classes one inherited from DataGridViewComboboxCell and other from ComboBoxColumn, in order to insert my own combbox or have the chance to have access directly to the combobox values. But the combobox showed is the default combobox not my own combobox.
how can I create a custom comboboxcell but using my own combo, and having access from outside to this combo?

I have already binded a data source from Access to my visual basic program but need to add a True/False column to two of the tables. I could do this manually in access and re-bind the sources but that would take up too much of my time so I wanted to know if I'm using the proper code to add a column to the data table directly from VB? Here is the code I want to try but I don't know where to place it?
OleDbCommand = OleDbCommand("ALTER TABLE tableName ADD
FieldName DataType");
(something).Connection = OleDbConnection;

I'm not sure what goes into the "something" parenthesis and where this code must go. I already tried editting through the data designer but although it shows the column in the DataGridView, it does not save any data or the column into the actual access file.

I am working on a program where the user inputs values, then the program calculates those values and outputs the sum. When the user hits the button exit then those values entered by the user are saved. When the user starts the program again, the values are still there. I wrote the code and everything works fine. I am saving those values in notepad... and the program grabs the input in notepad and outputs those values to the program. But here comes the problem: Lets say the user wants the information in a certain column to be added to another column somewhere in the program. Is that possible ? And if it is can it be done when I am saving those values in notepad?
