A singleton pattern for the event-handler class?
Formula 1 - Short for "F1 Racing" - named after the standard "help" key in Windows, it's a sport where participants desperately search through software help files trying to find actual documentation. It's tedious and somewhat cruel, most matches ending in a draw as no participant is able to find anything helpful. - Shog9

use some form of storage (database, XML, flat text, whatever) to store the last-used number and load that each time the form starts.

I don't really know what you are talking about. The two forms jumped back and forth so quickly I could not really see the screens. And my machine sucks.

hi
is there anyone know if microsoft visio can convert code to a uml class diagram and how visio does it ??
Allah give me love for all people , talent is Allah's gift
|
|
|
|
|
Can Visio do that ? I don't believe so...

Yes, its called reverse engineering.
|
|
|
|
|
Yes. But you must use "Visio for Enterprise Architect".
You can convert :
Code -> UML Diagram
UML Diagram -> Code
|
|
|
|
|
Visio had the ability to do this as far back as VB5 (or maybe 6).
For .NET, I would assume that visio uses reflection to look at the types defined in an assembly, and creates the UML shapes from the properties/methods defined.

hello I just wanted to ask u abt how I can generate the PK values in a table that is being replicated as well. the subscriber can also enter new records. and there is only one subscriber though.
can I alter the table thru enterprise manager(sql server 2000) to include the identity property if not then what should I do.
I'm using VS .net 1.1. C#
whats the best suitable datatype for PK. I made it numeric (9,0) but now I think int would be better.. what dou say
thanks in advance

We use the high order bits of a 32-bit integer to identify the site. We use 7 bits, which gives us the ability to have up to 128 sites, where each table can have approx 32 million records per site.
If that is not enough, you could always go with 64 bit.

i don't think so that there is any direct way to change the structure of original table in database through dataset or datatable.

Hi,
to add a new column to the database table you have to run a DDL-statement. Normally it should look like this (exact syntax depends on the database system you are using):
ALTER TABLE "Student" ADD COLUMN Age int
You can execute this statement using c#, if you are using for example ADO.NET. Just create a statement (like you do when you want to insert a row in one of your database table) and execeute it.
Hope this helps a bit, if not don't hesitate to ask again.
Regards
Sebastian

I know it's a stupid newbee question, but I have looked everywhere and can't find the answer....
I know how I get data from a dataset to a datagridview but how do I get data from a dataset to a textfield?
My code:
private void loadFakturaVis()
{
try
{
//create a connection string to the access database
OleDbConnection cn = new
OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;
User Id=;Password=;
Data Source=" + myDB);
// Create the DataSet
ds = new DataSet("FakturaOrdre");
// Fill the Dataset with Kunder, map Default Tablename
// "Table" to "Kunder".
da = new OleDbDataAdapter("SELECT Kunder.KundeId,
Kunder.Navn,Faktura.FakturaID, Faktura.KundeID, Ordre.OrdreID,
Ordre.FakturaNr, Ordre.Antal, Ordre.VareNr, Produkter.Varenavn,
Produkter.PrisExMoms FROM Produkter INNER JOIN ((Kunder INNER JOIN Faktura
ON Kunder.KundeId = Faktura.KundeID) INNER JOIN Ordre ON Faktura.FakturaID =
Ordre.FakturaNr) ON Produkter.VareNr = Ordre.VareNr WHERE FakturaID=@fakid",
cn);
da.SelectCommand.Parameters.Add("@fakid", OleDbType.Integer);
da.SelectCommand.Parameters["@fakid"].Value = fakid;
da.TableMappings.Add("Table", "Ordre");
da.Fill(ds);
// The DataViewManager returned by the DefaultViewManager
// property allows you to create custom settings for each
// DataTable in the DataSet.
dsView = ds.DefaultViewManager;
// Databinding for the Grid's
dgrOrdre.DataSource = dsView;
dgrOrdre.DataMember = "Ordre";
}
catch (Exception ex)
{
MessageBox.Show("Exception" + ex);
}
}
Now I want to do following:
Nu vil jeg så gerne lave følgende i min kode:
//Databinding for the fields
txtNavn.Text = ????????
Now I want to get the FakturaID from the dataset and put into the the textfield txtNavn.Text - but I don't know what I shal put in the place of my questions.
Kind regards,
simsen

try
txtNavn.Text = ds.Tables[0].Rows[0]["FakturaID"].ToString();

Can any body tell me how to delete text from a PDF file?

The reason documents are published as PDF files is to guarantee the sanctity of the document. Especially when publishing something that has legal implecations (like an employment application) over the internet. You must have the Adobe Acrobat 7.0 and you probably need to be recognized as an authorized author of the document.
