I have the following:
a table of addresses and a bindingsource for the table
a enum list of address type: 0 = "Mailing", 1 = "Physical", 2 = "Shipping" etc...
I would like to bind the datasource of the combobox to the enum so it displays "Mailing", "Physical" etc. Then I would like to change the bindingsource position of the address table based on the user selection of the combobox.
Here is what I have so far:
cbxAddressName.DataSource = New BindingSource(ApplicationEnums.GetEnumList(GetType(ApplicationEnums.CompanyAddressType)), Nothing)

I'm using VS2008, VB.Net and WinForms. I cannot get the combobox droplist to display the most recently added item unless I quit the app and restart. I've searched thru several forums for answers but cannot get any to work for me

i have a combobox bound to an ObservableCollection:-
<ComboBox Name="combo" ItemsSource="{Binding Things}" SelectionChanged="ComboBox_SelectionChanged" >
in the code behind I have
Dim thingArray = New ObservableCollection(Of Things)
Me.combo.DataContext = Me.thingArray
Assume thingArray is initialized to 5 Thing objects and Thing has a toString() implementation. I want to display the first item Thing(0) by default on the ComboBox. How do i do that?

I have a combo box that has a drop down list with long values in the drop down
Ex:
LB - Pounds
GR - Grams
When the user selects on of the values I want to just show the Abreviaqtions and not the descriptions. So when the drop down is shown it shows
LB - Pounds
GR - Grams
When the user selects "GR - Grams" from the drop down list "GR" is the only this shown in the combobox. I've tried TextChange,SelectedIndexChange and SelectedValueChange but I can't get them to work.

In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?

This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!

SQL statements:
SQL = "SHOW TABLES;"
Try
conn.Open()
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.

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.

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.

I am developing a Windows Form Application against a SQL Server relational database. An example of the database schema is:
TableA
------------------
PK A_ID uniqueidentifier
A_NAME varchar(254)
[code]....
In the form I have a ComboBox (cboA_ID) to select the TableA record (DataSource = TableA, DisplayMember = A_NAME, ValueMember = A_ID) and a TabControl where controls on each tab are bound to fields in either TableB or TableC.My question is, is it possible to bind cboA_ID to TableB.A_ID and TableC.A_ID?This is my first database application so if there is a better way to do this I'm all ears. I have set everything up using the wizards in Visual Studio 2010, so I'm still not 100% familiar with what all the various TableAdapters and DataSets do.

I am attempting to read an XML and display certain portions of the XML in a datagridview. I was able to get one table at a time, but I am having trouble figuring out how to get ALL the info I want from the XML and not just one table at a time.
I was speaking to someone and they told me that my issue is that the dataset contains datatables and it's not just one big piece of information that I can use. I looked into merge code, but I haven't managed to get anything working the way I would like.[code...]

I have two tables: One wich contains the columns "first_name", "last_name" and "status_id". The other table contains "status_id" and "description".
Now, I want to display "first_name", "last_name" and "description" in one DataGridView. What is the best way to do this?
What I'm doing now, is that I'm manually adding a datacolumn to the first table. Then I'm looping through each row and filling the new column manually. Now, that doesn't seem very smart and efficient, but I haven't found any better solution.

I've been trying to use lookup tables to display names instead of ID's in a DataGridView using a DataGridComboBoxColumn and have even copied the example shown in the Forms over Data videos produced by Microsoft but still get the following error message:System. =Argument Exception:DataGridView ComboBoxCell value is not valid..Everything was done in the designer and the problem only occurs with the DataGridView; lookups work fine using a combo box when displaying single records.Also the error message only pops up when I close the form. Prior to that all the names are displayed correctly for each record, the drop down list shows the names correctly and I can edit, add and delete rows and save all my edits with no problems. Its just when I close the form that the problem occurs.Each time I press OK in the message box the names in the combo boxes are removed, one by one.

i have to create a mortgage calculator (I know we have killed this mortgage calculator). Has to display an amortization table to display the list after doing the calculation. Here is the actual assignment:
Write the program in VB.Net (not Web based) and have it accept user input of the amount, term and interest rate. Display the mortgage payment amount. Then, list the loan balance and interest paid for each payment over the term of the loan. The list will be longer than the screen, so use loops to display a partial list, hesitate, and then display more of the list. Insert comments to document the program.
I have created 4 buttons. Calculate, Clear, List, and Exit. The buttons all work, but the list does not. Not sure what i am doing wrong.

I'm writing an assignment in VB for a class which displays records from an Access database. It goes as follows:
From a "Rooms" table, I get the rooms to be displayed in a combo box along with 3 checkboxes which will tell me if they have a jacuzzi, private access of a fire place. From a different table in the same database I need to display in text boxes the bed size, weekday and weekend prices for booking each room. The text boxes should display the correct information according to what was selected in the combo box, but I can't get that to work! The checkboxes work fine, but the text boxes stay the same.
Here's what I have so far:
Private Sub Rooms_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
Dim RoomsData As New RoomsDataTier
Dim RoomsDataSet As New CottagesDataSet
RoomsDataSet = RoomsData.GetRooms

I am writing a UserControls that display different database tables in textboxes. At present, I change which table the UC looks at by means of a Property that is in byte format and the Set part of the Property calls a subroutine to fix various functions.
Public Property csrCategory() As Byte
Get
Return category
End Get
[code].....
When, say Line 2, is selected the value 2 is passed to the value in the UC.
