DB/Reporting :: 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.
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?

DB/Reporting :: Collect Data From Table And Insert Into New Row
Jan 4, 2010I have an access database with 3 tables, want to collect data from 2 and insert them into a new row in the third (although this seems redundant there are reasons for wanting it that way). I created a form and call the data from the two tables fine, once the form is filled I try to add a new row to the third but it will not add the row even though it is telling me that is has. When I open my access table the record is not there. I am new at this and just can't figure out why it won't work, I have tried several approaches the latest is
Code:
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Dim IDNUM As String = InputBox("Enter Student ID Number")

Oct 29, 2008My company is making thousands of products now, every one of them have several test report in excel files. I am thinking about putting all of them into a microsoft sql database,
1. Is it wise to do so? I think a sql database is a lot easier to manage.
2. Can I save or convert the excel file as one data in a table? How could I do it? I only see a image type for data type. Surely I expect to retrieve the excel file through ASP.Net website if necessary.oh, some additional info, every excel file is not big, but it contains pictures inside sometimes.

View 1 RepliesIDE Stop Filling In The Rest Of A Property When Creating A New Property?
Nov 5, 2011when I'm creating a new property in Visual Basic .NET in Visual Studio 2010, the rest of the Property (template?) doesn't complete the basic framework of the property in the code editor. It is now treating a statement like:
Public Property Length() As Integer
Instead of completing the property as it used to (code follows), it simply goes to the next line:
Public Property Length() As Integer
Get[code].....
What happens now is that, if I type in the 'End Property' code, the name of the property will now be highlighted as an error since it doesn't have a 'Get' or 'Set' portion.However, when I THEN type the 'Get' on the line following the 'Public Property Length() As Integer', then the balance of the property is created in the code automatically.I don't know how this got changed, but would love to change it back.Does anyone know if there's a setting in VS2010 that addresses this, or if it's something with the basic templates that visual studio uses for creating the basic code components?The weird thing is that for everything else, from class declarations, structures, functions and subs, the IDE still creates the balance of the code structure correctly. The only area where it doesn't is for Property declarations.
Filling Table In DataSet And Filter Information
Apr 6, 2009When I use a command such as:
Me
.TableAdapter.Fill(Me.SomeDataSet.Table)
I am going out to the database, gathering the requested information and filling the dataset. Therefore, everytime I add a query to a table adapter, it is also going to the database to get the information. So, my question is, how do I fill a table in a data set with all the records in the database table and then, filter the information I've already collected in the dataset without going back out to the database again?
Sql - Invalid Cast Exception When Filling Datatable Wth Table Adaptor
Jan 13, 2011I am using VB.NET 2010 (Visual Basic 2010 Express) on a WPF-based project. I am also using the SQL Server Express built-in to Visual Basic 2010 express.I have just about finished refining my code for hooking up my wpf-based form to an existing SQL database (agentroster.sdf). I have a global data source (AGENT_ROSTER) connected to this database. Connections are confirmed to work properly.This is the first part of the code I'm using, irrelevant code omitted,
Dim table_adaptor As New AGENT_ROSTERTableAdaptors.AGENT_ROSTERTableAdaptor

Dim rowposition As Integer

how do I fill roster_table with table_adaptor (or alternate method)?

View 9 RepliesDB/Reporting :: Table Columns Into Table Adaptor?
Jul 7, 2011Rather than running numerous queries in Access I am trying to write a front end for a DB2 database. The Access database is getting to a size that it is causing Access 2007 to have reliability issues and frequent compacting is required. I have created the Dataset, the Table Adaptors, and the Connection String already, but when I put in a bit of code in to fill the Table Adaptors the remote connection I have to work is going crazy (chewed up about 180MB before I realised it was pulling data from work).
Before I started the project I copied the .accdb to my local PC HDD and I pointed the connection string to it, but it still looks like it is trying to pull data from the work network. If it was a small database I wouldnt be concerned but it is pulling major data every time I run it. I have only 2 out of the 4 Table Adaptors running and it didnt fill them even after 10 minutes.
Here is the code I was trying to run... Server name has been substituted for Server for obvious work reasons.
Because the tables are so large I was looking for a way to pull only the columns I need to from the tables, I tried adding .SOFT_ID to the first line of code but the TA spat the dummy message below...
Value of type 'System.Data.DataColumn' cannot be converted to Application_Name.DS_DB2Database.Server_SOFTDataTable'.
Code:
Me.TA_ServerSOFT.Fill(Me.DS_DB2Database.ServerSOFT.SOFT_ID)
Me.TA_ServerSOFT_FOUND.Fill(Me.DS_DB2Database.ServerSOFT_FOUND)
Me.TA_ServerHARD.Fill(Me.DS_DB2Database.ServerHARD)
Me.TA_ServerREF_SUP.Fill(Me.DS_DB2Database.ServerREF_SUP)
I would also like to pull just the data columns I need to speed up the query.
Note: In case youre wondering why I am not connecting directly to the DB2 database. I currently dont know where it is stored and while leveraging Access I am trying to put a level of separation between the app and the db for the time being, later I will try connect directly.
