Weird how the retarded questions always flood in at the same time of day

1 - help is not a valid subject. Everyone wants help
2 - is google broken where you live ?
3 - did you not see the search box for searching for articles ?

Registry code in C# is very easy, and there's tons of documentation on how to do it.

Re: How to map data from dataAdaptater to dataset correctly

14-Apr-09 22:04

Hi

I need a few help to make a correct mapping from my dataAdaptater to my dataSet:

SqlConnection conn = new SqlConnection("Data Source=localhost;Initial Catalog=JWDTA016;Integrated Security=True");
DataAdaptater.SelectCommand = new SqlCommand(QueryString, conn);

//I try to create mapping
DataTableMapping mapping = DataAdaptater.TableMappings.Add("Table", "dt");
mapping.ColumnMappings.Add("IXROOT", "Client root");
mapping.ColumnMappings.Add("IXADID", "Addres id");
mapping.ColumnMappings.Add("IXPATH", "PDF Path");
mapping.ColumnMappings.Add("IXID", "Document id");
mapping.ColumnMappings.Add("IXESEQ", "Extraction sequence");
mapping.ColumnMappings.Add("ISSTAT", "Status");
mapping.ColumnMappings.Add("DIFREQ", "Sending frequence");
mapping.ColumnMappings.Add("IXPID", "Production id"); 
  
//But when I display the ds into my datagrid, it can just display all my dataquery result and not only the colums i want to map         
DataAdaptater.Fill(dt);
Ultragrid.DataSource = dataGridData.Tables[0].DefaultView;
Ultragrid.DataBind();

If somebody has an idea or see some wrong in my thought process...

regards

What's the responsibility of controller?

14-Apr-09 22:05

I don't believe C# supports DTD files. Even if it did, it's certain the dataset class does not know how to mangle the data it has to try to fit to a DTD. You're out of luck. You can validate XML against a schema in C#, but you can't give C# a schema and some XML and expect it to reformat it for you. Your best bet is to look at the XML that comes out of your dataset, and write an xslt sheet that modifies it to fit your schema.

Hi,

I have applying MVC pattern in windows forms application, but I got a problem that I am not clearly understand the usage of controller, for the application, I created a controller and fill in lots of functions to control different area of object, now, it became the "god controller"(same as god class with ~150 methods), but it doesn't contain business logic, it just perform the object creation, object flow between DAO and notify events for UI display in about five set of domain in an enterprise.

Could anyone provide some guideline / hints to help for clearly understand the responsibility of controller?

Thanks.

Some of that is already applied but the controller is too large, I think it contains a lot of "Get Data from Model and Give it to View" code in the controller.

e.g.
for payment, the view should load all PaymentMethod, all Branch and all division for user selection and bound the Payment object with Payment details, so the controller for this case contain GetAllPaymentMethod(), GetAllBranch(), GetAllDivision() for user selection

Some of other part of the application contain more then three GetXXX() so it become too large, so I want to clarify about it.

1. Should controller handle object creation method? I have already separated a Factory Class for object creation, but should view directly call the factory or call the controller to create object from factory?

2. Should controller handle GetAllXXX() method for user selection? or let view call it directly?

3. Should controller handle flow between object and DAO? e.g. Update(Payment obj) { PaymentDao.Update(obj);}

4. Should controller provide interface for domain model method? e.g. ShipOrder(Order obj) { order.Ship(); orderDao.Update(order);}

Thanks

Hi,

I have a document that gets printed to a label printer via the PrintDocument class.

(Partial listing)

PrintDocument pd = new PrintDocument();

pd.DocumentName = "My document";
pd.PrintController = new StandardPrintController();
pd.BeginPrint += new PrintEventHandler(OnBeginPrint);
pd.PrintPage += new PrintPageEventHandler(onPrintPage);
pd.EndPrint += new PrintEventHandler(OnEndPrint);
pd.Print();
pd.Dispose();

My question:

Is there any method within the PrintDocument class that can reverse the printing for me. As I am sending to a label printer, it is important that the bottom of the label is presented first as it comes out of the printer.

-Regards,
David Bailey.

When you're printing, are you just using a Graphics object?

If so, then you can set the Graphics.Transform to be rotated by 180 degrees

Hi benjymous and thanks for your reply.

I have in my possession Charles Petzold's "Programming Microsoft Windows with C#" and did try a few things such as RotateTransform(180f) etc. Only some of the output swiveled like it should. Your comment at least helped me to work out why...

I am MOSTLY using a Graphics object to draw with. But I am also using a GetHdc() of that graphics object to draw some rich text via use of the RichTextBox. This output is remaining steadfast.

So is there anyway to rotate the output of a PrintDocument? Should I be using something else? Or will I have to rotate every individual element that I am trying to print?

Any help, suggestion or clue will be greatly received.

- David.

If you're stuck with the HDC stuff, you could just drawing everything to a bitmap first, then draw that bitmap to your final printer graphics object with the transform set.

What do you mean by 'code behind' ? This is not the ASP.NET forum. I assume it can be done with the Microsoft tools for Office, which expose Office to .NET code.
