Store One Column Into A Combobox?
Nov 20, 2009
I have a table called PatrimoniuMasini.
What I need to do is simply copy all the values contained by column NumarMasina into Combobox1 of my Form. (i marked with red the values I need to copied into my combobox(combobox1 of my form) in fact there are 10 values I missed the last one. You can run the ddl provided below in sql server to see the output from my printscreen.
When I run the form in my combobox there are imported the values from NumarMasina column. (so this must be done in form_load callback it's sure).
Just need to import the values from column NumarMasina of table PatrimoniuMasini automatically into combobox1 when I start my application.[code]...

I've been able to add my own non-bound columns to a DATAGRIDVIEW - such as a check box column.But I'm not seeing how to take a bound column and make that column be a combobox. Doesn't appear to allow that.Do I have to hide the real column and add a "fake" front-end column that I make a combobox?

i think its hard to explain, but here we go.I have a combobox, where you should be able to add item (in this case colors/Hexcode selected from colordialog).So lets say we have 3 items in that combobox:and if you pick blue, the color blue should apper in a background color.I can only get names to work, but i cant find out how to store the hex value data.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

switching our database over to UTF-8 (multi-byte char, unicode) encoding from IBM819 (single-byte char, Latin1 subset), because of a new requirement to support text entry of Czech characters.I've just been reminded by a colleague of the nchar and nvarchar column types, which neither of us has actually ever used.
If I were to define the relevant columns as nchar and nvarchar instead of char and varchar, what would I have to do to allow my currently-IBM819 database to work with this new IBM819-incompatible text coming in from my .net application?Would all conversion be automatic? Would I need to write some scary conversion code?
EDIT: Right, I defined an "nchartest" table containing a single column, "ntest" of type nchar(500).I connected to that via .net code and confirmed that 500 chars of lorem ipsum could be entered:
Dim insertString As String = "INSERT INTO nchartest VALUES (?)"
Dim insertCommand As New IfxCommand(insertString, cConnection, tTransaction)
insertCommand.Parameters.Add("incident_recno", IfxType.NChar).Value = "[lipsum]"
Return insertCommand.ExecuteNonQuery
I then replaced the lipsum string with 100 or so chars of Czech text, and attempting to insert that caused an IfxException to be thrown by the .net Informix interface, with the message ERROR [HY000] [Informix .NET provider]Unspecified System Error = -21005.
Following up on some research I did yesterday, I tried setting my CLIENT_LOCALE setting in my connection string to en_US to match that reported by Threading.Thread.CurrentThread.CurrentUICulture, but that connection could not be opened due to ERROR [HY000] [Informix .NET provider][Informix]Unable to load locale categories.
Following that, I tried setting CLIENT_LOCALE=en_US.unicode, which produced an ERROR [HY000] [Informix .NET provider][Informix]Unspecified System Error = -31142.

I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to:
read/write/delete from it
read possibly up to a 20mb file and sorting it without a lot of lag
be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.

I have a datagridview containing 1st column (combobox), 2nd and 3rd column is textbox. The combobox was filled-up using datatable. My problem is on loading form, I will get a records from my database and set the value of my combobox base on those records. So if I have 5 records from my database then I should have 5 rows containing combobox in my datagridview.
I tried the code below but there's an error saying "the following exception occured in the datagridview...." but it will display correctly, but if I click in any cell that error always appear.

I finally got my last project done and Im updating it and making it more efficient. So instead of DGV to list users what Ive done is using a combobox to list the agents names in the database. I got that part done and I have that table as the datasource for the combox and that part works fine. However Im wanting when they select the Name from the combox it gets the values from the columns and displays them in the appropiate area. Ive tried like SELECT PhoneID FROM agents WHERE Agentname =" & comboname.text, but I cant get it to work that way.

I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

I am using the following code for a combobox to display a series of codes depending upon the value entered in combobox1. This works fine except the column being displayed contains a 6 character field (A99999) and I would like to display only the last 5 numeric characters rather than the whole column. otherwise I shall have to add an additional field into the table which contains just the numeric part of the code.
Dim LowestVal As String
LowestVal = ComboBox1.Text & "00000"
Dim HighestVal As String
