VS 2005 Updating Client Data Tables When Data Table On Shared Drive Is Updated
Sep 28, 2009I 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
VS 2005 : Pick Specific Parent Control?
Dec 11, 2011I have a form with a tabcontrol(6 tabs) with a groupbbox on each tab page containing numerous NUDs. The NUDs need to be checked for either 0 (double) or 0.0 (decimal). I don't want to have to do this over and over:
vb.net
If Me.nudLinealFeet.Value = 0 Then
MessageBox.Show("Lineal Feet cannot equal 0.", "No Value Given")
End If
[code]....
but I can't figure out what to do since there are more than 1 "parent controls".

VS 2005 : Searching Data Table?
Nov 3, 2009I 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
[code]....
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?
VS 2005 Add Data To A Hash Table?
Mar 19, 2009Currently 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.

Feb 11, 2011I 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.
