If I have this to read from an access database, how could I translate it to read from an oracle database with the same table/field information? I know nothing about oracle but I assume I cannot use the oledbdataadapter that I am used to when connecting with an oracle DB.

I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.
Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
I have two questions:
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it

have made the data table in vb code, and it works flawlessly. It gets its values from labels which are part of a calculation.It shows the information to the user in a datagridview. Now i would like it to add new rows and fill them in if the user has already entered the data once and it has been logged in the datagridview.here is the current

I am using Visual Studio 2005. I am using a data reader to read an Excel spreadsheet and want to update a SQL Express table. The datatypes in this table mimic a software application I will eventually be passing data to and are listed in the comments in my code. No matter what I do or change, this will not run. I even populated my spreadsheet with zeros and this will not run. I have found many suggestions on the web and tried changing things but nothing seems to work. I also don't know specifically which variable is causing the error or the proper way to make sure there are no blanks in this spreadsheet.The error says "conversion from string "" to 'Double' is not valid Here is my code:
Public Sub btnUpload_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpload.Click
'Connect to the Excel spreadsheet
Dim xConnStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & txtFileName.Text & ";" & _

I am having to create a data adapter to pull data into a dataset, then loop through that dataset in order to add information into a new column from a separate data source. My first data source is access. My second data source is oracle. Here is the code I have to do this, which works well when I show it in a grid.
Dim da As New OleDbDataAdapter("SELECT tblSummary.WorkOrderNumber, tblLabor.Crew, tblLabor.NumberOfMechanics, tblLabor.NumberOfHoursPerMechanic, tblTasks.TaskNumber, tblTasks.TaskDescription FROM (tblLabor tblLabor INNER JOIN tblTasks tblTasks ON tblLabor.TaskID=tblTasks.TaskID) INNER JOIN tblSummary tblSummary ON tblTasks.JobPlanNumber=tblSummary.JobPlanNumber WHERE

how I can search through this data table. For instance, I want to see only rows that are in this data table that have "Replace" somewhere in the "Description" field, which is the field I added from my second data source. How do I do this? Is there an easier way to do all this instead of filling my dataset from the first source and then adding columns from the second source by looping?

Currently I add data to a hash table, then later on I loop through the hash table. To my horror I discovered that when you use FOR EACH with a hash table it doesn't return the items in the order you added them.I'm looking for a collection that I can add, edit and delete items from and loop through from start to end in that order.

I start with a text file containing information such as this: Monday, Tuesday, Wednesday, Thursday, Friday 12:00:00.1, 12:00:00.1, 12:00:00.1, 12:00:00.1, 12:00:00.1 I made up the values of course but the idea is exactly the same. I need to have an if statement that if the text document has a record of Monday, then it is to put something like an X in the corresponding column in a data table. I'm sure I confused this way more than need be but I hope you get the most of it and I can elaborate if need be.

way to do the following in VB 2005:
I need to access, but not display, a web page out of a VB 2005 program. The web page would be an aspx page with a query string as part of the url - with the url using values acquired thru the program - e.g. www.mysite.com?arg1=this&arg2=that
So the aspx page would produce an html output with values I need placed in specific elements. I want to read that page from my app and do stuff with the resulting values.
