Updatable Label Text According To Combobox Filled With An Access Database?
Apr 16, 2012
I'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.

I have a form that I am loading text (strings) from a database into a label.text (so the text from the database shows up into the label) I have done this code in a class that keeps all my database stuff seperate.
Public Function getQuestions() As List(Of String)
Dim question As New List(Of String)
objConnection.Open()
objReader = objcommand.ExecuteReader
[CODE]...
Within the form that the label is in I have done this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text(db.getQuestions().ToArray)
End Sub
I am basically making a quiz, so that when the form loads, question 1 is on there is 4 possible answers. You then press next button and it goes to the next question.

I tried Firebird with .NET Provider yesterday. Firebird was sure to beat SQL Compact Edition. I was amazed from it's features and precision. But I felt sad when I wasn't able to find updatable RecordSet/ResultSet features and functions in the .NET provider. FBResultSet doesn't contains anything, no rows addition, creation, modification, nothing. Anybody knows if this feature exists in Ado .Net provider of Firebird because there's no documentation.I would like to receive help because I am waiting to integrate Firebird in my freeware application.Also, if there's are replacement functions for implementing updatable RecordSet, ResultSet.

It's necessary that if we choose an item in the combobox we also get the id of the table.How do we put the id into the combobox so can read this id after selecting an item.

My.Settings.Current_DB is bound to 'cbdatabase' which is a combobox which is filled by this method:
me.cbdatabase.datasource = (From foulder in New IO.DirectoryInfo("" & Application.StartUpPath & "Database").GetDirectories Select (folder.Name)).ToArray I am using the My.Settings.Current_DB to keep track of the current database being used by the client. So that throughout the program and when the program starts up it knows what the current database is.
The databases and the folders have the same name, in order to keep track of. My problem is when the combobox is filled when the program starts, it is overwriting the current info with the first item of the info loaded into the combo box.
[Code]...
Instead of maintaining the Current_DB as "Default", it updates it with the first item into the Combobox and that is "Alabama". How do I fix this so that it maintains the correct Current_DB and not update when the Combobox is filled.

I have a form with a combobox that is filled with a list of parts from a mysql DB. But the table contains more then 1000 parts. So I decided to load only the first 20. then have 2 bottuns 1 for UP and one for Down. when the user wants to get next 20 he press Down Etc. I see that the data is retrived well from the DB. I use a stored procedure with parameters and test it outside the VB code. In the VB debug I also see that the combobox got loaded with the right data. But the drop down list continue to show the original 20 parts. I also have a code to see if I got to the top or to the end and display a message box. I got the message box display but still the drop down is showing the original 20 parts.

I have names of all labels in a table of an Access database (one field is a form name- it can be repeated, the second field is a label name - it must be unique for the same form, the third field is a text of this label). E.g. the first record has field1="Form1", field2="Label1", field3="Smith" My question: How can I refer to a label programmatically using the Access database? E.g. Form1.Label1.Text= "Smith" In C languge there was the opportunity "remove the quotation marks" from the text ("Label1") and get the literal (Label1). Is this opportunity in VB.NET?

I 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.

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.
Like one column is for countries of origin.
United States
Canada
Mexico
In the combo box, it should only list the United States only once, not multiple times.

The program consists of making 2 text boxes, one labeled Age, and one labeled Name.The Name text box must return the name in all uppercase.If the Age text box isn't filled with a numerical value, you should receive a message saying "need a number" and return your cursor to the age box.2 command buttons "Process" and "Exit"
I tried getting started, but I usually always work better when i have a beginning!

Those who are looking for an example like this, might find it useful (or not). I know i was looking for one like this for over a week. Ok now, to make this codes work properly, you have to make a Database in Ms Access (I used MS Access 2007) . Create a table of two Columns, one name Debit and one name Credit. Both of the Columns Data Types must be Long Integers or you might get some conversion errors at run time. Now save the database in Access 2000-2003 Database format. And last of all, put the database in your projects DebugBin directory to avoid the database Connection Errors.
