View 5 RepliesI'm trying to connect a VB application (2010) to an MS Access DB by adding a data source from the data menu but I receive this error message "The connection you selected uses a local data file that is not in the current project.Would you like to copy the file to your project and modify the connection ?
If you copy the data file to your project, it will be copied to the project's output directory each time you run the application" and the options are (yes , No , Help)
If I choose Yes I will not be able to make the application 'device independent ' since it will not be copied under the bin , and if I choose No , changes won't be applied to the DB
when this button is click, it will retrieve all the records in different fields in MS Access 2007 and display onto the RichTextBox. But when i run the code and press the retrieve button, an error occurs. (NullReferenceException was unhandled. Object reference not set to an instance of an object.) Plus im sure my code to display records on richtextbox is wrong as i created another project purely with a button and a richtextbox, only the last field in access is displayed.

View 1 RepliesI have a problem when trying to retrieve records from my Access database through WCF. In my application the user enters a Customer ID and the function then searches the database and retrieves all records related to that customer. However, it isn't working as it should. The code behind the search button is as follows:
Private Sub SearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SearchButton.Click
[Code]...
this code isn't doing as it should. The DataGridView should display the records relating to a customer but nothing is being returned at all, I'm not even getting any error messages. I've been looking at it so long I must be missing something ,
rs.Open("select * from CSOptions where OrderNumber = '" & cbstrCurrOrderNumber & "' and OrderLine = " & CBLI, strConn, 2, 2)
If rs.EOF Then
rs.AddNew()
End If

I'm trying to retrieve record data from an MS-Access database and store it into a variable. i'm using this SQL command to query the database: Dim cmdRead As OleDbCommand = New OleDbCommand("SELECT UserID FROM [User] where Username=?", conn) How do I do it in VB.NET to read data from the UserID column (in the db) and store it into a variable in VB.NET?
What I basically want to do is to retrieve the UserID so that I can then retrieve the Name and Surname of the user from the same table.
Note: I'm using ASP.NET with Web Develop 2003 and an MS-Access 2003 db.

To retrieve a list of Views in my Access database, but now I want to retrieve the results based on a selected View. Is there a correct method in doing this, or do I take the SQL Statement from the DataTable returned for each row?
Although a few people around here have said that Dates are not a huge deal that they're simply data, I always seem to get stuck on them, and my current issue is no exception. I am trying to save/retrieve data between my Access 2003 data and my VB2005 form. I have tried any number of combinations (even the forbidden Value.ToString, and having the Data Type in Access as string, and although it worked fine for saving the data, it doesn't work for loading it back into the form.). Here's my code for saving the data to the database:

View 11 RepliesI am new convert from VB6 and needs some help developing a stand alone application in VB 2008 that needs access to stored data values.All applications I have developed so far have been for computers that have either SQL Express or Access installed locally on the computer. This has made development really easy since I could use ADO to access and query the data.
The application I am now developing will be installed on a computer that does not have any of the MS office applications and I do not want to install SQL Express on the computer. But I still would like to use an 'ADO type' functionality to access, query and modify the data stored in the system.I started looking into using XML, but I was unable to find much information on querying and modifying individual elements.
How do I make a basic Data Access application (Next, Previous, First, Last, Update, Delete, Insert, Save)?

How can access file from the application.

View 3 RepliesBasically I want to know how to access a particular website from my application. I have used System.Net Namespace to request HTML from a website, It returns a complete HTML code which is used by Browsers to render the content on the screen but what i want is to interact with the website only without the use of a browser. I currently dont know how to do that.
I have a application which displays a Image when a user enters a keyword, lets say user enters a word "Envelope", the application will go to Google Images and search for this keyword. Now google returns images as results, the application now needs to download the first result ( which is a image) and display it on a form ). Everything here is done without a browser but via my application.
