I know how to pull data from an access database and place it into a combobox, but I am trying to make certain that I dont have multiples of the same information.

After trawling around the net for a good few days, i decided to post something here.
Basically, i've got a problem linking a data source (Access 2007 database) to a VB 2008 project.
I've broken it down to having a problem dragging a table onto my form, when it generates the nav bar, it says "0 of {0}", and the table is empty (despite the actual database containing values)
However, this happens only at home, at college it works totally fine. The only difference that's obvious is that i'm using Windows 7 at home, and Windows XP at college.
When using SQL connections in my program, will I have to open and close the connection and the data reader each time I want to access the database ?

I am trying to import data from an access database to a access database that my project uses I am having problems with combo box fields in the database with the data. I want to import what is displayed instead of the numerical key value. Example: The combo box displays employee names but the value stored is the key value from the employee table so instead of importing John Doe it imports 2 is there a way to make the actual name instead of the number?

View 14 RepliesI am using VB 2008 Express to connect to an Access 2007 database. I have a combo box called SelectYearMonth that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
When I made a report in Access using VBA I coded my calculation as:
Me.ExactReprintTextbox = DSum("Pages", "HBELP_FINAL_Q", "YEARMONTH = " & [SelectYearMonth] & " AND JOBTYPE = 'E'")
While this works great with Access VBA, this syntax does not work in VB 2008 Express. How do I code this in VB 2008 Express?
I need to calculate the sum of all "Pages" of a particular "JOBTYPE" in the Access database for the YEARMONTH selected in the combobox. I have a query in Access called "JobTypeExact_Query" that contains all the pages of that particular JOBTYPE that I need. What I need to do is limit the calculation results to the YEARMONTH selected in the combobox.

View 1 RepliesI'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.
this code links to the access database but but I just get only the first row in each combobox...
