View 5 Replieswhen 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

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()

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?

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 2 RepliesI'm making a timer program, that I want to be able to store "unlimited" timer profiles, that someone can load and use. Now I've created a form that you fill with data, which then gets saved to a .xml file in a pre-defined directory. I'm now working on some sort of code that will:
1. Search the directory for .xml files
2. Find any .xml files and convert names to strings
3. Store the strings in a dropdown menu, so that when one is chosen, it loads that profile.
I think I have 1 down:

Dim di As DirectoryInfo
di = New DirectoryInfo("C:Simple Timer")
di.GetFiles("*.xml")
