Dataset To Retrieve Some Data From An SQL Database And Then Uses It To Populate A Listbox?
Jan 19, 2009I have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String)
Try
TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.

View 8 RepliesCombo Box Event To Select Certain Data From An Access Database?
Nov 30, 2010I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum and place the results in a text box. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
The combo box is called "cboYearMonth" and is populated by my database, this is working correctly.
The text box that I want the calculated results to appear in is called "ExactPagesTextbox"
I have a query in Access called "JobTypeExact_Query" that contains all the pages that I need. What I need to do is calculate the total number of "Pages" limited to the YEARMONTH selected in the combo box. YEARMONTH is a value in every record in this query.
