• Visual C# InvalidCastException with Windows Media Player / IWMPPlaylist

  I'm working on an audio application that makes use of the Windows Media Player COM Component. I'm using my own Playlist class because I want to be able to provide some additional functionality that the built-in WMP Playlists do not support, like the Playlist determining the Play Mode (shuffle, repeat, etc.) instead of the Player. After hitting some walls using my own Playlist class, I realized I need to use WMP's IWMPPlaylist interface, so I decide to make an Adapter class to implement all the methods that IWMPPlaylist defines without muddying up my own Playlist class. I'm not entirely sure Adapter is the right pattern name here, but that's what I'm calling it for now. My class is defined as such: class PlaylistAdapter : IWMPPl ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Not Understanding Game Components

  I'm new to XNA - I'm making a 2d version of pong (nothing exciting, but it's a start). I'd like to be able to do something like.... foreach(gameObject myObject in AllObjects) Sprites.Draw(myObject.Texture,myObject.Vector,myObject.color) It seems resonable. I was going to create my own 'gameObject' class to encapsulate all of the logic and drawing and what not for every sprite in the game. Isn't that what a gameComponent is supposed to do From my broad understanding, you just add a gamecomponent into your collection and the Draw and Update will be called automatically. Is that what I should be using here; if not when do I use the gamecompoent Any help would be greatly appreciated. You might find the X ...Show All

• Visual C# Why Modifier can't be set like C++

  I am using C++ Language and learning in C#. But I used to set Public modifier as class cls { -----param public : -----method and param } Why C# don't have this. I think all modifier should be able to set as this method like C++. And can set like Java too. Or Microsoft has some reason Why it can't is syntax. Why it was designed that way has already been pointed out: to clarify member modifiers and to increase quality (by avoiding accidental and un-obvious modifier changes because a declaration's class offset was changed resulting in a different modifier). ...Show All

  Hi, I'm building an application to monitor users so as to prevent them from abusing the PC. This program must not be stopped. How can I disallow users to terminate my program I found out that if I want to terminate ZoneAlarm's vsmon.exe from Windows Task Manager, I'll get an error message "Unable to Terminate Process: The operation could not be completed.

• Visual Studio Express Editions Reading, Converting, Writing a Hex file?

  I am learning C# in Visual Studio Express. I am trying to re-create a program like I had in VB6 (which was originally from QBasic). What it does is ask the user for a filename (I have this part figured out and it works), opens the filename and reads it into memory strings: The file consists of hex data, So I would guess that means using the BinaryReader But I can't read the data into a string defined field in C#. How can I do this example VB6 code:    Open fi For Binary As myfile   'read entire file into buffer    buf1 = Input(109120, #myfile)    buf2 = Input(4, #myfile)    buf3 = Input(97000, #myfile)    Do Until EOF(myfile)     b = Input(1, #myfile)  &nb ...Show All

• Visual Basic IDE annoyances

  While i absolutely love the new visual studio, there are a couple of things that drive me nuts!!! when i right click on a symbol in code (such as a variable or procedure name), i can choose "Definition" and jump to that location. unfortunately, the "Last Position" menu item (that was available in VB6) was removed so now i cannot jump back to where i was previously. when i want to save my file with a different name, i would normally choose "File->SaveAs". this has now been changed to include the file name, which i find to be reallly annoying, especially since i will not be using the same name. opening visual studio is really quick, but closing visual studio takes forever. opening the design (GUI) view takes forever. switch ...Show All
