• Visual Studio 2008 (Pre-release) Why are the ClientBase<TChannel> ctors protected?

  With the service contract in a separate assembly it is really nice to be able to share the same assembly between the client and service. Then you can create a generic proxy client without the need for svcutil. (The same way you should share an interface for .net remoting). Unfortunately this requires writing a generic helper class that derives from ClientBase<TChannel> because all it's ctors and InnerProxy property are protected! Why oh why Please make this class more accessible for this scenario. The client base is a class you should inherit from when creating your typed client proxy. If you wa ...Show All

• Visual C# Accessing the Windows Scheduler

  Hello, I have written a set of classes to calculate a schedule for the monthly, weekly, daily, or hourly frequency that an event in my application will fire. After writing the application, my client has requested that the operation more closely resemble the operation of the Windows Scheduler.  Rather than reproducing the entire Windows Scheduler functionality, I was curious if there was an easier way to use the Windows Scheduler interface. I know some libraries exist on CodeProject that allow you to interact with the Windows Scheduler, but nothing seems to give you access to the actual forms the scheduler uses.  Also, I am ...Show All

Storing the text is no problem but when reading it again it is truncated at approximately 32kBytes even though the total text physically exists in the attribute. We have to use the XML format of the Word documents. Are there any size restrictions for Word XmlNode attributes Are there other possibilities to save with the document text which is not visible to the user Can we use the data islands when using the Word XML format Thanks, Joe The Attributes collection is really an XMLNodes collection.

• .NET Development XmlSerializer and MemoryStream: Byte Array has NULL

  I have copied code found in several places that allows me to serialize an object to a string using XmlSerializer and MemoryStreams.  I'm not using StringWriter because I have to use UTF-8 to be compliant with a particular web service to which this XML will be sent. I found that the resulting string had a leading null character and that this prevented deserialization necessary for further manipulation. I do not see the leading null when using a StringWriter instead of MemoryStream, but the resulting XML has a declaration of using UTF-16. I can get rid of the leading null with Substring(1) but that seems weak. I haven't seen any post ...Show All
