I have made a front-end application in Visual Basic .NET that will store data entered by the user in a backend Access 2003 Database. The application has other functionality as well.If the user searchs for a previous record that has been stored in the Access Database, I query the Database (SELECT ... ) using an OLEDB Connection and then display the records on a Datagrid on my Form. Everything is working fine, however, the Column Headings of the Datagrid are the Field Names in my Database (FirstName, LastName,...) rather than Caption Values (First Name, Last Name,... )
I tried looking up the net, but most of the topics addressing a similar problems use DAO, and I understand that it is not completely supported in VB .NET.

Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 11 Repliesi seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:

I am writing a math game for my brother in Visual Basic to help him with double digit numbers(both adding and subtracting).Normally you solve a problem by writing right to left on a piece of paper. Is there any way of setting the text box to do this?
For Example:
58
+ 18
You would type in the text box '6' followed by '7' so it would read '76'I set the right to left property but it does not do what I want it to do.
I am working on an assignment, so need to pass the file to the instructor. I thought I remembered a way to input a placeholder character(s) that tells the computer that the path is flexible until the point where I declare the actual path.
For example: if the directory is C:documentsMyProjectinDebug on my machine, and is F:usersownerclass assignmentscis101StudentAMyProjectinDebug on the instructor's machine, can I put a "wildcard" type of character that points to the ...MyProjectinDebug file that will work on both machines in the Initial Directory property?
I am trying to write a Project to keep track of my favorite sports teams and scores and store and retrieve the data from a database. I am using vb.net and accdb files. I am able to connect to the tables( 3 tables Players'Keep track of individual stats',OpposingTeams'Keep track of who my team played',Games'matches between the two teams') and Visual studio made it easy to display the teams in comboboxes but this is as far as i can get.

View 2 RepliesDoes anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?
