• Giridhar Damodaram How to use generated assembly?

  I have a dotnet dll name test.dll after using sgen I got test.XmlSerializers.dll Now my types in the generated dll are suffixed with “Serializer” keywork i.e If I have testclass I get testclassSerializer type in the generated dll.

• Matthijs Koopman Behavior of XPath Query to find attribute that had the maximum value

  I have the following Xml: <Books><Book id="10"/><Book id="16" /><Book id="12" /><Book id="18" /></Books> I wanted to get the Book node that had the highest "id" value (<Book id="18" /> node in our case). The following XPath query works perfectly fine. /Books/Book/@id[not (. < ../preceding-sibling::Book/@id) and not(. < ../following-sibling::Book/@id)] I was trying to understand this query and changed it to: /Books/Book/@id [(. > ../preceding-sibling::Book/@id) and (. > ../following-sibling::Book/@id)] Note that I removed the not operator and changed the comparison operator. However, I find that the above query ...Show All

• James Miles "Work around" the one base-class limit

  Hi all, I would like to add some extra functionality to several existing classes. The implementation of this extra functionality is exactly the same for all the classes. Unlike some other OO languages (like c++), the .NET framework only allows one baseclass to be used, so I cannot put this implementation in a single class, and derrive my new class from the both the original class AND the class with my extra implementation. One way to work around this, is to add one property to each of the derrived classes which contains an instance of a class with my new implmentation. But, I would rather extend my classes directly with the new properties and methods. Is there any way I can accomplish this without have to resolve to copy-paste ...Show All

• OnFileOpen how to create .xml file using SQL query (SQL Server 2000)

  i'm using a datawarehouse from which i need to pickup huge data and show it using a grid on a web page. my thought is to create an .xml file suing SQL query and then create a dataset from the XML file and then bind it to a datagrid do any one have any better(best) approach for this   I don't see any advantages in creating intermediate XML file What stops you from populating dataset directly from the query with DataAdapter for instance Of course query results can be returned as xml if you append FOR XML AUTO clause to select statement, but I'm not sure how are you going to use it anyway. actually the requirement is like this: 1) Its a mi ...Show All

• TboneToo How to set a File's Version Info

  Hello, I know the System.Diagnostics.FileVersionInfo class which works fine. Now I need a method to set the FileVersion, not only read. Is there a possibility with plain .Net 2.0 Thanks Sven There's no support for that in the framework. It's not easy to do at all. The only API Microsoft provide for changing native resources (which is how the version info is stored, as a VS_VERSIONINFO resource) is the BeginUpdateResource and related functions. But that still requires you to know the detail on how the information is stored. Hello, thank you for your reply. I would like to change it for existing files. Regards Sven Do yo ...Show All

• JKountouroglou Optional value type pointer/reference parameter during COM interop

  Hey, I am facing an interesting interop problem that I haven't found a solution for yet. Let's say a COM method takes a pointer to a simple struct: HRESULT Foo(LPBAR pBar); Let's also say that this parameter is optional and the call pInterface->Foo(NULL); is perfectly valid. Now, if the structure BAR is defined in C#: [StructLayout(LayoutKind.Sequential, Pack = 4)] public struct Bar { // ... }; and the COM interop method call is also defined: [MethodImpl(MethodImplOptions.InternalCall, MethodCodeType = MethodCodeType.Runtime)] public void Foo(ref Bar); In this case, there is no way to be able to call Foo(null) in C#, although it would be valid. The question is: how do I let the Marshaler know that it should pass ...Show All

  Hi, I'm having problems with SmtpClient.Send() where I end with an "An established connection was aborted by the software in your host machine" type error. My infrastructure people tell me that I should have access to the Smtp server so things should just work. I've been googling and searching forums but have yet to see a complete answer to what this error is trying to tell me.

• Maramil TableNewRow event doesn't fire

  Any idea why the TableNewRow event doesn't fire in an example such as the following DataTable dt = new DataTable ( "Test" ); dt.TableNewRow += new DataTableNewRowEventHandler (dt_TableNewRow); OleDbCommand cmd = new OleDbCommand ( "SELECT * FROM ... ", _connection); using ( OleDbDataReader r = cmd.ExecuteReader()) dt.Load(r); Kind of annoying, as I'd hoped to use this event to keep track of progress as data trickles in. The query takes about 20 minutes to return all data, due to a slow network connection. I'd really like to be able to keep the user informed as data accumulates. Any other suggestions Please use RowChanged event for DataTable.Load ...Show All
