How to link my app to an Access database - there seems to be a number of approaches. I can add in my database via the Data Sources tab. Fine if I want to bind controls and view/edit data. But is this the best approach for queries that return an answer that is a different shape to the original table? Alternatively I can connect to the database directly (connection string, etc) and run sql queries. What are advantages/disadvantages of each approach? In terms of flexibility, is the second approach best? Also, does the second approach require the database to be added via the Data Sources tab?

However, I got error of "The ConnectionString property has not been initialized." on da.Fill(dt) when running the second time. First time was successful.OK I finally got mistake corrected. I gotta Dim cn As New OleDbConnection("Provider = Microsoft.JET.OLEDB.4.0;" & "Data Source = C:Class.mdb") again to use query instead of once for all queries.
Has anyone a sample code, or point me towards a guide on how to link in a Query from an existing Access Databse into my vb? Im wanting to populate some text boxes with information from a query.

View 20 RepliesSo i'm creating a simple application as an example that is to link to a Access 2007 database.
On my main form i have four listboxes that are correctly attached to the table, I have one for First Name, Last Name, Phone, and School. I added 3 records to the database in Access to see if I could display the records in the listboxes on the form. I found that it was very easy by setting the properties and I have no problem there. I also have a command button that loads a new form for the purpose of adding a record to the database.
Here is my main form (frmMain.vb)...
CODE:
And Here is the code for the form...
CODE:
What i'm looking for is when the user presses the Add button on the frmAddNew form then it needs to close and the new record is listed in the textboxes and saved to the database. Id also like to know all kinds of things i might be able to do with textboxes and databases because i'm trying to learn for a larger project where i'll need to keep track of hundreds of records.
I understand that this is a simple procedure, but i've been spending all night scouring tutorials and getting lost in the msdn library online, so maybe some human input will be better.
I am working on a project that requires us to create a bracket type tournament and I am now stuck. I linked my access database to my project, and have 32 labels (lbl1-lbl32) and I cannot figure out how to integrate the labels to read from my database. It can be random or not, I just cannot get the labels to display the names of the fighters.
After the labels are integrated, the next coloum of the bracket has a link that opens a new window with each of the fighters match results, does the link have to include anything particular to display the attributes from the database?
The project must have different user and each has username and password will be saved in my database but only the admin can add users.

View 3 RepliesI have a link here that works perfect for calling the postback close that I need to happen:
<a href="javascript:parent.__doPostBack('Close','')"><asp:Label ID="Label5" runat="server" Text="Close Me"></asp:Label></a>
However, I would like to be able to call the *javascript:parent.__doPostBack('Close','')* method from the code-behind file rather than the user clicking the link. I.e., when I have completed my tasks in the application code, call parent.doPostBack as my last function call, which closes the window in question.

How do you access a link with rel="alternate" using process.start?
Dim Internet As New Process
Dim InternetAddress As String = eL(DiUs, 0)
Internet.StartInfo.FileName = InternetAddress
Internet.StartInfo.WindowStyle = ProcessWindowStyle.Normal
Internet.Start()
eL(DiUs, 0) is a link to an RSS, but the post won't show unless the link is rel="alternate". How do I do that?
<link rel="alternate" href="http:..........." type="text/html" />
so I'm using Visual Studio 2010 and I'm trying to make a program where I would have a textbox where the user would type,then a "Go" button. In the textbox, the user would type a number, lets go with 1 for an example. A user would type 1 in the textbox, then it would automatically add the 1 to the end of this .swf link: "http:[url]... after they enter the 1 in the textbox and press the "Go" button, it would add the 1 to the end of that link, then that link would open a new shockwaveflash form with the link being the Movie. Is this possible?

View 3 RepliesI have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.
All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden. Dieser Vorgang konnte nicht durchgefhrt werden, da der QueryInterface-Aufruf an die COM-Komponente fr die Schnittstelle mit der IID "{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}" aufgrund des folgenden Fehlers nicht durchgefhrt werden konnte: Schnittstelle nicht untersttzt (Ausnahme von HRESULT: 0x80004002 (E_NOINTERFACE))."}
For all who can't read german:
"Microsoft.Office.Interop.Access.FormClass" can't be converted in to "Microsoft.Office.Interop.Access._Form3" ... Interface is not supported.
Code I use:
Dim access As Microsoft.Office.Interop.Access.Application = Nothing
