I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

I have a combobox that is bound to a BindingSource that contains a custom object with multiple Properties.
Is there a way to access a Datamember that is not displayed in the combo box and display it elsewhere. For example, When a user selects a name from the combo box, texboxes (or Labels) populate with Title, PHone, email, etc. All of this data is loaded in the custom object that is bound to the datasource so the info has already been pulled from the db and is in memory.

What I am "trying" to do is to take a combo box control on my form, and load it up with data from an access db, but I dont want them to be linked so that when I change the combo box to another value it will cahnge record data. From the pics attached I have manage to load the data into the combo box, but the 2 are linked and when I try to change the combo box it creates violations in the database as its trying to change the records.

I 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.

I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.

I'm trying to get a combo box to fill itself from a MS access database field but I can't get it to work. I can get it to work at school but not at home. Also can't get a program that worked at school to work here so I'm guessing that somewhere there is something blocking the connection to the database. I've gone into the MS access trust center and looked at the settings there but I can't see anything that would be stopping it. I just need to find that setting (if it is indeed a setting) wherever it is and fix it so that I can access my database. I am not using visual basic from access I am accessing access through visual basic.
I can't get it to work with an ADO connection, either. Also when preview data via clicking smart arrow on the combo box then going to preview data I can see the data just fine. Also I just noticed I get two lines in my output after the file is run that say "A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll" I don't get these lines if I comment out all the code for the combo box.

I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

I'm trying to bind a combo box to a Access database field. I'm trying to do this with code instead of using the data sources wizard as I was told that this would be more flexible and better if distributing the finished program to other computers.
The result is that the form runs, but nothing is in the combo box.
I have also not used a dataset in my code, only a data table. Am I correct in thinking that this is plausible?

I am teaching myself VB, and when I first managed to do what the post title says, I ended up with a combo box filled with values from the column of a table in a linked db. But later when I updated the VB Form and tried linking the database on this revision of the project,and then added the details to the combo box where to read the values and run the form, nothing displays in combo box. Here is what I did:In the IDE of VB, I went to "Add New Data Sources" -> Database -> New Connection -> Browse -> (selected filename of db) -> Next -> Select "yes" (put in current project) -> Next (save connection name) -> tick boxes for tables in database to connectThen in combo box control properties i set the Data Source (Other Data Sources -> Project Data Sources -> (dataset name) -> Table Name
