• Visual Studio Tools for Office Mo Actions Pane in Word 2003 - newbie question.

  Hi. I've been developing Office solutions int .Net for about a year now. My company had some proprietary code that was letting us place user controls in Word (Document Map) but it's time to phase that hack out with Office 2007 coming. So I downloaded VSTO (the version currently distributed) and installed it. Then I started looking around for code samples how to attach a custom Actions Pane. It appears that if I start an Word 2007 project in VS2005 there is ActionsPane but if the project is for Word 2003 - there is no such property and no obvious way of getting a public property that would do. I'm not sure if I'm doing something incorrectly and it seems more and more frustrating after 3 days of digging around. After initial atte ...Show All

• Visual C# Generics type parameter attributes

  Hello, I've been reading the C# 2.0 Language Specification and have come across something I don't quite understand. In the section detailing generics, the following definitions are given: type-parameter-list: < type-parameters > type-parameters: type-parameter type-parameters, type-parameter type-parameter: attributes opt identifier The last line surprised me... I've never seen attributes used in a type parameter list. Are there any examples of such a construction being used in real-world code Am I reading this incorrectly or does this say that something like: class C<T, [attr]U> {} would be a legal construction Go easy on me..

• Game Technologies: DirectX, XNA, XACT, etc. Drawing Primitives with Xna

  I can't seem to be able to find any documentation on how to draw 2D primitives in Xna (lines, triangles, circles, squares, verticies etc....). All the documentation relating to 2D Xna seems to be about sprites. I'll give an example of why I need this and if someone could tell me the best way to do this, that would be great. I'm making a magneticfield demo in which you place a charge somewhere and you move around another charged particle. Then, the demo draws a vector relating the two particles (using coulombs law). In order to do this, the magnitude of this drawn vector will have to be changed. Thank you very much. You might be better off using the System.Drawing classes and GDI stuff ins ...Show All

• Visual C++ a++++; what abt ++a++

  hi i hav this problem. int a; a++++; gives an error.. ' operator ' needs l-value but ++++a; compiles properly. plz help me... I hope you're not actually writing code this way! If you need to increment the value by two, just say "a+=2;". The difference between ++X and X++ is that in the former X is incremented before the evaluation of the rest of the line, while in the latter it's evaluated afterward. "++++a" is evaluated as "++(++a)". I'm not sure how "a++++" would be evaluated, and I suspect the compiler feels the same way. ...Show All

• Visual C# Object Oriented Programming

  Hi all. Im a C++ Programmer that just moved to C# and am having problems learning about classes and objects, i just cant seem to understand it. Im not sure whether i have the wrong book, so any advice and help on the best place i can learn OOP for C# from would be much appreciated. Thanks. I read both the books you referenced in the opening posts both are very good if you follow along and work through the examples. The Binary Tree example is a great sample that shows you what objects are capable of. Also they go over class constraints and some of the common interfaces, which can lead to very powerful uses of Generics (C# flavor of templating) Some things that are new from C++: *Get and Se ...Show All
