It runs on whatever color depth you're using.

Hey Mr.Christian Graus can i send you my source code to test it..????

I have some grid controls on a form that are using data adaptors to fill the grid directly from the SQL Server data base. I have added an even handler on exit of the form to commit changes but the changes are not getting written back to the data base.
Here is my code -
this.speciesTableAdapter.Fill(this.markingDBDataSet3.Species);
private void MasterData_FormClosing(object sender, FormClosingEventArgs e)
{
SpeciesGrid.CommitEdit(DataGridViewDataErrorContexts.Commit);
SpeciesGrid.Update();
}
I must be missing something or I am totally on the wrong track. Any ideas?

Ok. To update the database based on changes you have made in the datagrid you must be calling the DataAdapter.Update() method. This takes two arguments: Your datatable/dataset (this will be the datasource of your grid), and (if you hand it a dataset) the name of the table.
Ex.
dAdapter.Update(somedataset, "Table");
or
dAdapter.Update(sometable);
But you do need to specify an insert command in order for this to work. If a standard insert query is fine, you can use the command builder class. So, if you are using OleDb it would be like this:
OleDbCommandBuilder cmdBuild = new OleDbCommandBuilder(dAdapter);<br />
dAdapter.Update(somedataset, "Table");
Hope that helps!

I am using a SqlDatatAdaptor and when I try this solution, it builds without any errors but when the update is executed, I get the following exception error -
Update requires a valid UpdateCommand when passed DataRow collection with modified rows.
This is my code -
SqlDataAdapter dAdapter = new System.Data.SqlClient.SqlDataAdapter();
dAdapter.Update(markingDBDataSet3, "Species");
|
|
|
|
|
You need to include the SqlCommandBuilder to make your update command for you:
SqlDataAdapter dAdapter = new SqlDataAdapter();
SqlCommandBuilder cmdBuild = new SqlCommandBuilder(dAdapter);
dAdapter.Update(markingDBDataSet3, "Species");
Without this, the update will not work.
|
|
|
|
|
I added the code as sugested -
SqlDataAdapter dAdapter = new SqlDataAdapter();
SqlCommandBuilder cmdBuild = new SqlCommandBuilder(dAdapter);
dAdapter.Update(markingDBDataSet3,"Species");
I am now getting a different error.
Error -
The DataAdapter.SelectCommand property needs to be initialized.

Sean, you got me pointed in the right direction. I worked with one of the more experienced Windows developers here and we managed to cobble together the following which seems to be working. Evidently it needed a reference to the table adaptor and needed a select command added to the data adaptor.
Here is the code -
SqlDataAdapter dAdapter = new SqlDataAdapter();
SqlCommandBuilder cmdBuild = new SqlCommandBuilder(dAdapter);
dAdapter.SelectCommand = new SqlCommand("select * from Species");
dAdapter.SelectCommand.Connection = speciesTableAdapter.Connection;
dAdapter.Update(markingDBDataSet3,"Species");
Thank you very much for your help!

Ohh sorry I would have told you to put a select command in when initializing the data adapter but I thought you had just left it out so you wouldnt take up to much room in your post 
Good to see you got it workin'

Hi there,
I'm using DataGridViewCheckBoxColumn, when a check box is unchecked sometimes I get the value {} (it's not a string value) instead of false. I want to get the value false or true.
Does anybody know why do I get the value {} and how can identify this value programatically?
Thanks in advance,

Is there a way to access the resources in referenced assemblies ?
e.g. <asp:Label ID="Label2" runat="server" Text="<%$ Resources:MyResources, MyText %>"></asp:Label>
but with a MyResources assembly that was referenced instead of resources in the global_resources folder

If i have this codesnippet and the specified url doesn't exist.
How do i catch the webexception?
WebClient laddaner = new WebClient();
laddaner.DownloadStringCompleted += new DownloadStringCompletedEventHandler(laddaner_DownloadStringCompleted);
laddaner.DownloadStringAsync(new Uri("http://thisurldoesnotexist.com"));
Right now i get a TargetInvokationException thrown at Application.Run(new Form1()); in Program.cs (the program is a simple Form-app)
This doesn't work:
WebClient laddaner = new WebClient();
laddaner.DownloadStringCompleted += new DownloadStringCompletedEventHandler(laddaner_DownloadStringCompleted);
try
{
laddaner.DownloadStringAsync(new Uri("http://thisurldoesnotexist.com"));
}
catch(WebException)
{
MessageBox.Show("Error!");
}
|
|

|

try using WebClient.OpenReadAsync() and check the OpenReadCompletedEventArgs.Error in the handler for OpenReadCompleted event.

I have 2 forms.
disable some buttons;
form1 call some bool function on form2(via a delegate).
this function will print some stuff on a textbox in form1 via a cross thread handler.
if the function return true then enable the buttons.
simple enough. but vs2005 give me this error:
"Cross-thread operation not valid: Control 'button1' accessed from a thread other than the thread it was created on."
Does anyone knows what is going here? And how i can solve it?
