Well Windows Update uses a service called Background Intelligence Transfer Service (BITS). You can use this to download files or updates, then you'll have to write some code to update your application.  Of course you dont have to use BITS, you can write your own downloader or use WebClient.DownloadData/File if you dont mind it holding up your app...

Hi gurus,
With WMI and C#, how can I detect if a network adaptor is a virtual or physical?
Thanks.
Best regards.

You can't check for a flag like that, but you can use the available information to POSSIBLY figure it out. Most virtual adapaters will not have an AdapterType in their Win32_NetworkAdapter class. Physical adpaters usually will. For example, you could check each adapter for an "Ethernet 802.3" Adapter Type.

Hi,
It seems that I have the correct information when I do the following SQL statement on WMI:
SELECT Description, IPAddress FROM Win32_NetworkAdapterConfiguration WHERE ((DHCPEnabled = 'TRUE') AND (IPEnabled = 'TRUE'))
But I don't know if it will work on manually configured ethernet adapters.
When I do a request on Win32_NetworkAdapter class with the AdapterTypeID set to 0 (Ethernet 802.3) I get back the 1394 adapters and a lot of other adatper types while I need only to retrieve physical network Ethernet adapters (no virtual ones).

No, it won't. Even VPN adapters can have those properties set to True. Also, not all properties of the class are set by the drivers manufacturers. AdapterTypeID, since it is available in XP and above only, might not be set. It, also, does not support a NULL value, so if it is not set properly, or at all, it defaults to 0. Use the string parameter AdapterType instead.

Hi Gurus,
What is the equivalent of the MFC's combo member SetItemData and GetItemDatain C# for combo boxes? 
Thanks.
Best regards.

Hi - not a guru here but what I use to populate a combobox is: combobox.Items.Add([value]);
Not sure what you need to use to replace GetItemData I use an equivilency test eg: if([value].Equals(combobox.Text))...ect but there maybe a better way.
Hope this helped

Hi,
thanks.
I have found how to add personal data to combo box items
thanks anyway

I don't know if it is what you found out, but you can add any object to a ComboBox, and it's the result of calling that object's ToString() what gets displayed in the ComboBox.
So, just create a little class that contains all your data in public fields (or properties or whatever) and override the ToString()member. Add objects of that class to the ComboBox, and that's it.

Hello everybody. I'm writing from Seville, Spain. I'm trying to build a Test-generator application through a shared add-in hosted in Word, and I need to transform .xml documents to other formats like .doc, .html and .rtf. I'm convinced that possibly there are libraries, components or classes that allow these transformations.
Does anybody know something about this respect??
Has anybody ever been in a similar situation??
Thank u very much

C# code:
public static System.UInt16 MAKEWORD(byte a, byte b)
{
return (ushort)a | ((ushort)b << 8);
}
when compiling,the error "can not implicitly convert type 'int' to 'ushot'" occur.
what's the problem?

You'll have to cast the return value.
public static System.UInt16 MAKEWORD(byte a, byte b)
{
return (ushort)((ushort)a | ((ushort)b << 8));
}

Hi...
I have made an xml document, and uploaded it to a server...
my problem is how to uploade it again after i downloaded it..!
When i download it i do this... (not sure this is the best way to do it)
string path = @"http://www.whatever.com/web/MyFile.xml";
WebClient DLoad = new WebClient();
DLoad.DownloadFile(path, "MyFile.xml");
that works fine...!
But then when i want to uploade the file..
I have no idea how to do however i tried this...
WebClient ULoad = new WebClient();
string path = @"http://www.whatever.com/web/MyFile(1).xml";
ULoad.UploadFile(path, "MyFile.xml");
But it throws an "'System.Net.WebException' occurred in system.dll -
Additional information: The remote server returned an error: (405) Method Not Allowed."
I have no idea what to do now....
Need a way to upload the file to the server.... or to write to the xml that already is on the sever...!
Can anyone help me please...?
Thanks....!

Hi All,
I have bound textboxes and other controls on a panel. If I edit the text in a textbox and move on to another control, everything works fine and I can use
HasVersion(DataRowVersion.Proposed)
to determine if there have been any changes to any control.
BUT, if I make only a single change to one text control and leave the panel afterwards by clicking into another panel on the screen, the proposed version flag is not set and I'm missing to save the change to the underlying dataset and database.
Binding:
txtCode.DataBindings.Add("Text", m_vProject, "code");
...
and after leaving the panel:
BindingManagerBase bm = BindingContext[m_vProject];
cPrjDs.tProjectRow prjRow = (cPrjDs.tProjectRow)(((DataRowView)bm.Current).Row);
if (prjRow.HasVersion(DataRowVersion.Proposed)) {
if (MessageBox.Show("save changes?", "header", ...)) {
bm.EndCurrentEdit();
To my understanding, it would be possible to catch the TextChanged event of the control and start DataRow.BeginEdit(), but this does not seem to be a practical solution for lots of controls.
Thanks for any help.

when i make a new windows application project and put in the main webform any control like a Button, the application throws overflow exception, but if i tried to run the application without making anychanges the application will run without exceptions, i think the problem isn't in the control because after i got the exception i removed the control from the webfrom but i still have the same error, i don't know why i got this exception while am setting the Checking Overflow/Underflow to false in the project Build properties,
anyone have suggestions ?
thanx in advance .

Hi, just want to know what you guys do when you wish to populate DataGrid with DataSet consisting ALL customer records BUT not wanting to load ALL customers records into DataSet (or in other words, memory). For example,
DataSet dsCustomers = new DataSet();
//That's not good, you're potentially loading enough records into memory to bring down your application server.
SqlDataAdapter daCustomers = new SqlDataAdapter(
"select * from Customers", conn);
daCustomers.Fill(dsCustomers, "Customers");
dgCustomers.DataSource = dsCustomers;
dgCustomers.DataMember = "Customers";
Thanks!

AFAIK the DataGrid has no way of dynamically loading data. There might be another grid implementation that does support...
Anyway, loading all your customers into a grid isn't a good UI practice. Its impossible to navigate that much information and make use of it. I recommend that you rethink your design to minimize the data to exactly what the user wants to see. Just a suggestion.

Yes, I can ask user to specify a WHERE clause, but solution would be nicer if I dont have to. I think you're right though - the whole point of DataSet is grab all data from SQLAdapter and work disconnected from data source - propagating changes only back to source only when you're all done in the end.
DataGrid.DataSource is anything that implements IEnumerable - Classes that implements this interface includes DataView, ArrayList, and Hashtable. IEnumerable includes one interface method:
IEnumerator GetEnumerator();
Which returns IEnumerator interface - which includes three interface methods:
1. object Current {get;}
2. bool MoveNext();
3. void Reset();
I think one can implement their own IList class, which resembles this:
class CustomerList : IList {
protected int _count=0;
protected Customer _current=null;
protected SQLConnection _con=null;
protected String _sql=null;
public CustomerList(String sql, ref SQLConnection con) {
_sql=sql;
_con=con;
}
property Object Current {
get {return _current;}
}
property int Count {
get {return _count;}
}
bool MoveNext() {
...grab directly from database everytime...
Customer cs=null;
int currentUIN=_current.getUIN() +1;
String filter=" WHERE UIN=" +currentUIN;
String sql=_sql +filter;
SqlCommand cmd= new SqlCommand(sql, _con);
_con.Open();
SqlDataReader rdr= cmd.ExecuteReader();
if(rdr.Read()) {
cs=new Customer();
cs.UIN=currentUIN;
cs.login=res.GetSqlString();
cs.email=res.GetSqlString();
... the rest of it...
_current=cs;
_con.Close();
//Get total count: "SELECT COUNT(*) FROM Customers"
... implementation ...
return true;
} else {
return false;
}
}
void Reset () {...}
}
Then, consuming it:
SQLConnection con=...;
String sql="SELECT * FROM CUSTOMERS;"
MyArrayList customerList= new MyArrayList(sql, con);
dgCustomers.DataSource = customerList;
Of course, you don't get the convenience of SQLDataAdapter.Update(), which propagate changes back in a batch --- ... is it possible to blend DataSet (100% disconnected) and CustomerList (100% connected, grab data as you go) and have the better of the two...

I urgently need to create street-level mapping for an area in which there is no available street-level mapping from anywhere. Can somebody indicate as to how I can go about creating such a mapping (e.g. using a paper map to pass coordinates on a c# program to draw the map? can i use a database to store the points?) I am a relatively new C# programmer just starting out on GDI+.
Thanks
Chris

Use a GIS system - many will have the ability to digitise data from non-digital sources (e.g. Paper maps)

Most GIS systems will do this. Some are internal databases, others are more open.
Do you want to know more?
