VS 2008 Updating Data, SQL Express 2005?
Oct 6, 2009
I have noob question. I made a dataset of a sql express 2005 database using the designer. So it's a typed dataset. Then I declare some tableadapters and fill them.Now I do this to add a record to my dataset:
Private Function SaveOrder(ByVal controlenummer As Integer, ByVal PK_BaanID As Integer, ByVal starttime As DateTime, ByVal stoptime As DateTime) As Integer
Dim orderRow = dsIntveen.tblOrder.NewtblOrderRow
orderRow.Controlenummer = controlenummer
orderRow.FK_Baan = PK_BaanID

I'm using a SQL Express 64 database on a separate server virtual machine. I've been developing my app for some time now in VS2008 on XP SP3. Using .Net 3.5 I've just come across a strange problem. If I update a checkbox from unchecked (the default) to checked, it saves OK. If I click to uncheck it, the change does not get saved. I'm using the UpdateAll method. I tried a single Update command as well, just for that table, but it was the same.

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

I'm using Visual Basic Express 2008 to create an interface with a order database in MS Access 2007 (.accdb file). Everything is fully functional except updating the "Inventory" table is very slow. Updating around 2200 items takes almost 2 minutes and the window will appear as "not responding" for the duration if you click away and come back. Here is the process:1. Tab-delimited text file is picked by user, which includes all inventory items (not just new ones)2. Each line from text is parsed and read into variables (tempSKU, tempItemTitle, etc.)3. Old items are updated and new ones are added. -> This is the bottleneck
I used to have a series of IF statements to check which elements were changed and report them, but that was about 2x as slow. The new code is a little faster but doesn't provide the feedback I liked (update part is commented around):
Private Sub btnImportInv_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) andles btnImportInv.Click

I have a class which I'm binding to a series of textboxes, date pickers and so on. When I change text in the text boxes, the object updates just fine, and when I then save the data, it has the changes. My problem seems to be with the RTB ... if I bind to the .Text property, it works just fine and updates like any normal text box. However... when I bind to the RTF property... changes to the object don't happen unless I first click out of the RTB... quite annoying. If I edit the text or change the formatting, and hit the save button, the changes don't get reflected in my object. I've even tried using debug statements to track when the property is changed, and I'm not getting the results I desire.

I am working on a project that stores data on animals. I am trying to make updates to data already stored there, through inputs on a VB form. A form where all the data is populating the fields shows up and the user can change/update any field. Once they are finished, they click update and the DB is supposed to reflect those changes (Theoretically)However, I wrote the code to do that, but when it runs nothing in the database is changed and nothing gets done, as it seems. No errors appear and nothing goes wrong with the program. It just doesnt change the data in the db.

I have been learning about working with databases and VB. I have coded the connection string for a MS Access database to my VB project but i cannot establish a connection with my sql mdf database.
The code i used to connect to MS Access is:
<Dim dt As New DataTable()/>
<Dim match As String = ""/>

What is the connection code in order to manipulate data from the mdf file. Is it similar to the above code.

I have a little big problem in one application.
I have a datagridview with data from a datatable, this datatable have these fields (id,num1,num2, date,user,ref,qt,cost,center), some of them are hided in the dgv (id,num1,num2,date,user). The user can edit,delete and add new rows to the dgv.
I have a save button that performs this actions:
First check if there are new rows, and if yes it fill the hidden fields. Then validate the inserted values by the user with a couple of ifs. In the end, i call the bindingsource EndEdit, and call the adapter Update command against the datatable...
This sometimes works others not really, i don't understand why.
The error it's: "Concurrency violation: the DeleteCommand affected 0 of the expected 1 records"
I think sometimes when Updating it occurs to.

I have a program that uses a database for all of its information. The program is just an easier way to understand all of the information.The user uses 1 of 4 search options (FName, LName, MemberID or Startdate). Depending on what they search for depends on which members are displayed in a data grid view.
Upon selecting the desiered member from the data grid view, information about them is then displayed. This information has been split up over 3 tabs called member information, Attendence and payment history.
That all works great. So I now go to the Attendence Tab and wish to update this members attendence by selecting a date from the date time picker, and select the Add attendence button.This also works fine, the attendence is update but the attendence data grid view is not updated automatically.
I have to select the member from the first data grid view to run the code to refresh the members information.So I thought, call the PopulateAttendenceHistory Private sub again and have it update the data grid view... but it still doesnt work.

I am new to SQLSever, Visual Studio and Visual Basic. I have read through Microsoft Visual Basic 2008 by Michael Halvorson and Microsoft Visual Studio 2008 by Lars Powers and Mike Snell. These books mention the ability to use SQLServer as the DB but I am not clear on the process. I am not knew to programming an have had training in OO programming but have never done any OO programing professionally. So, you can assume I am new to OO programing.
I have created an SQL DB using the Server Explorer in VS, and created a Windows form with Labels, TextBoxes, and ComboBoxes for the application's user to add the demographic information about a new employee. I created a new query with the Query builder that is in the Employee table of the DB which contains all the field for the record for inserting. I have a few questions to understand the process for inserting into the DB.
The DB fields are defined as numeric(6, 0), nurmeric(5, 2), and char(30) for some examples.
The maxlength on the form windows are in sync with the maxlength of the DB for the various fields.
1. What is the process to update the DB with the fields from the form?
2. Do I need to declare and set the results from the form first? If so, how do I call the function (query) that I created in the Employee table.
3. The emp_num I would like to be a dynamically incrementing number starting from 1000. How do I make this a dynamic? The emp_num is also the key on the Employee table.
4. I have a decimal field on the Employee table to hold emp_rate (pay rate). Does the user enter the decimal on the Form or is this resolved by SQL to take the 7 numbers and insert the decimal beause of the table's field definition?
