Save Altered Dataset Back To The Database?
Apr 4, 2009
In my project,I used the wizard in VB.NET2008 Express to connect to my database. I have a data connector, adapter, and dataset controls on my form. I have been able to load the information into the dataset, and used the datCustomers.Customers.AddCustomersRow to add a new row to the dataset with information.
I now want to save the updated dataset to the database. I have tried using the adapterCustomers.Update(datCustomers) command to no avail. how to save the dataset to the database?

I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _
Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)
[Code]....
This displays the records perfectly and I figured out how to delete and insert records via web service.
writing updates from the datagridview back to the database.

I am writing a small windows client application that accesses data using a web service that returns datasets.When the dataset is returned, a datagridview's datasource is set to the dataset.
My question is, how do I write changes that were made in the datagridview back to the dataset and then back to the remote database.
[Code]...
Now the client snippet that connects to the service and lists the equipment

I'm using VB 2010 Express with a local Access DB. I am having trouble determing whether there are changes in a DataGridView to save back to the underlying DB.
The DB has been copied to the project directory and its properties (by selecting it in the Solution Explorer) include Copy to Output Directory: Copy Always, so I know that any changes I make when running a build will disappear on the next build. The problem I'm having is within a run / test session, working with the application.
The Access database has the following connection string, with Application scope:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source="|DataDirectory|Component MI.mdb"

I'm using the Visual Basic Express edition 2008 and I'm not able to save the changes to the dataset as well as dataset. While the application is running. I can see the changes are made in the table but the moment I close the application and check the data in the Dataset in the right window or the data in the database in the left window, I see no changesI have also tried the Update property of Table Adapter but no use. I have done Endinit, AcceptChanges everything but moment I clode the application no changes are reflected in dataset or databse.

I have created a program where I need to add, delete and update, I used a datasource and bound the items to a list. No errors occur and the data set updates, adds and deletes but the database doesn't. I have uploaded my program to a filehosting website as it is larger than 500kb and made the Main Menu the default form, please navigate to the first button or to the AddUpdate form and please help me to see where I have gone wrong.

I have implemented the filestream feature of SQL Server 2008 in a VB.Net application. I can insert files, and then retrieve/view them just fine. However, I have huge problems trying to update a file. Eg. The user selects a file from the grid which I execute via process.start. If that file is a .txt file, the user may choose to edit it. In case that happens, I need to save the changed file back to the database. So far I have failed to do that.
What I do, is take the retrieved file, copy it (cause i got some errors about it being used), and then Process.Start it. After that, via .NET filestream, I convert the file to bytes and try to update the record. SQL Profiler and a manual SELECT on the varbinary(max) column tell me that the file is updated properly, but the very next try to retrieve it I get an unchanged file.
After that I also tried to update the file by changing its File-System Version, but the file still wouldn't seem to update. Does Anyone have a code sample of how I can achieve this operation? Like 500 sites on the internet have examples of how to Insert And Retrieve the file, but not a single example on how to update. This is how my second attempt of trying to update the file via the filesystem looks like. The code for inserting/retrieving is very similar and it works properly. [Code]

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I recieve a failry complex XML from a web service (30+ tables; with nesting). I need to be able to look a this data; make mods and then pass it back (still well formed per xsd) to the web site. I am able to parse it both natively in XML and by putting it into a dataset. I am more comfortable working in a dataset so thought the best approach for me would be to take the XML to a dataset dsOrder.ReadXml(XMLreader) (also tried with inferschema switch) work with it as required; then using _newXML_str = dsOrder.GetXml
put the dataseet back into xml. This almost works, but the XML while well formed does not adhere to the schema. In particular, it appears that all the simple types for a table are put ahead of the complex types (even thoguh the schema wants some of these items intermixed), so when sent back to the web site, it complains about the order of the tags.
is there a way to get the xml from dataset command to form an xml that will ahdere to the schema? I tried using the available xsd to influence this process but it either doesn't work or I did not know how to apply it properly. If someone has a suggestion for this application I would appreciate comments and any detailed samples that come to hand. I am working in vss 2008; framework 2.0; and use vb.net.

I have a Sub with an array of strings as parameter:
Private Sub des(ByVal array() As String)
Dim i As Integer
For i = 0 To UBound(array)
[code]....
When I call the function inside my main function , the value of str changes even if the array is passed to the function Byval
Dim str() As String
str = {"11111", "22222", "33333", "44444", "5555", "66666"}
des(str)
I tried making a copy of the array in the Sub, but it still changes in the main function
Private Sub des(ByVal array() As String)
Dim i As Integer
Dim array2() As String
[code]....
I read on a site that you cannot pass arrays ByVal ,is this true? If so , how should I proceed?

What I have is a form I click on and it draws two ovals on the screen. I haven't formatted the second oval yet but is will color itself and place itself with conditions I have yet to create. What I'm stuck on is I need a way to save my work. Then Open it when I return or wish to see what I did. I am using the SaveFileDialog and OpenFileDialog to set/get the file but what I am have issue with is the code needed to save all the Ovals on the page and redraw them. Can one of you give me some guidance? Do I need to create a Serializable Class to draw my ovals to start with and not use the Powerpacks.Shapes?
