• Visual C# C# 2.0 doesn't allow me to use System.Void?

  I love generics in 2.0! What a time-saving feature, less code to write! Plus it allows for more code re-use, and thus fewer bugs. I love generics, pat on the back to Anders and the C# team. I ran into a limitation, however, with C# 2 compiler and generics. I wanted to implement a method that would have a generic return type, for instance: TReturn ExecuteSomeDelegate<TReturn>(MyReturnableDelegate<TReturn> serverMethodToExecute) {     // pretend there's lots of error catching & handling here...     return serverMethodToExecute(); }   This is all fine and dandy: // call some s ...Show All

• Visual Studio Express Editions sorry

  How do you create multiple lines within a message box when combining a string with variable values I know... it would probably be easier to just create a seperate form and load the form.... just wondering if it was possible to not have to do such though. What if the data that is to appear on the next line is - lets say - the value of an array. I'll explain my question. What if I want to display a list of values which the user entered....not for confirmation purposes but just to show what data had been entered...into a declared array. So.. Dim intArray(5) As Integer Element# Element Value 0 = 11 1 = 22 2 = 33 3 ...Show All

Thanks in advance   Hi Guns, what pattern are you trying to detect exactly e.g. class StreamWrapper {   private Stream m_stream;   public Stream Stream   {     get { return m_stream; }   } }   There are cases where it is completely legitimate to have a stream as a property in a class. e.g StreamReader/StreamWriter in the .NET Framework expose a property that give acess to the stream that the class is working on. ...Show All

• Visual C++ VC8, Adding __event to non-CLR code gives error C2712

  In a non-CLR class I have a number of __events defined. When compiling the source code in which the corresponding header file has these __events, I receive the error: error C2712: Cannot use __try in functions that require object unwinding pointing to the last of the __event lines in my header file. When I look at the error message it says: "cannot use __try in functions that require object unwinding". Further it is mentioned that "object unwinding" means "destruction". Needless to say I am not using __try anywhere but perhaps the code being generated by the __event extended keyword is. I have no idea what the function that "requires object ...Show All
