• Game Technologies: DirectX, XNA, XACT, etc. C# modulus operator % sucks?

  So in C# when I do -1%something I get -1, which means I can't really use it as an array index without a bunch of stupid error checking.  Is there some way to force the modulo operator to actually give me numbers from my field (e.g 0-5 for modulo 6) Edit: Well, I made this post at 2:00 am and it shows, here is what I have issue with: i = (i+1) % 6 will result in numbers from 0 to 5, which I could use for an array index i = (i-1) % 6 will result in numbers from 0 to -5, which can't be used in an array index Obviously, the absolute value of those results would not conform to any logical value, either (for instance, array[-1] and array[1] would be the same value, even though they should be 2 values apart if I decremented twice ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. No typedef and no Include. . .

  Are these VBA programmers writing the .Net framework and languages Many of you probably already know this, as I'm arriving late to the party. I wanted to use the typedef equivalent but apparently not in C#. Then of course I thought I'd try the #include -- maybe so, if I wanted comments (I gather). The end result: Common.cs using System; namespace <yoursHere> { using ID = System.Int32; public class objID { private ID itsID; public objID( ID theID ) { itsID = theID; } public ID ID { get { return itsID; } set { itsID = value; } } } } Did I miss something LOL I appreciate the comments, they were fun to read. ...Show All

• Visual Studio Clash between Studio 6, Studio 2003, and Studio 2005?

  I just recently got a new machine here at work. When I was installing software, I was careful to put Studio 6 (VB6 and C++6) on, THEN Visual Studio 2003 (.NET framework 1.1) and then finally Visual Studio 2005 (.NET framework 2.0). I need to use them all for my job, often in the same day. My current project is with C# 2.0, so I got that working right away. But I just got interrupted to go back to help with a previous project, which is ASP.NET & VB.NET (Framework 1.1). Visual Studio 2003 development environment comes up fine. I select existing project, find the .sln file, and load it. Shorly thereafter (within 2 seconds or so) the status bar says "Initializing offline cache..." and then Studio 2003 freezes. And when I say &q ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA and isometric

  Hello all,   what is the best way (if it is possible) to use XNA and build an 2d isometric view   draw a sprite and rotate it   or are there better solutions   thanks in advance..     g..   There is nothing stopping you from writing a game with an isometric view with XNA. You will either accomplish that by setting a particular camera position or by creating sprites that use an isometric view. Both methods are entirely possible with XNA but XNA does not do anything in particular to help you accomplish an isometric view. How you achieve the view is entirely up to you. Yo ...Show All

• Visual Studio Express Editions How would I randomize from a number set?

  Hi, I am fairly new to programming with visual basic. I have been looking around a while and I am still not sure how I could do this. I am trying to randomize, but not for example 1-20 like the normal function does, but I want to randomize a set of numbers, which eventually I want the user to choose. For example... I am making a schedule generator (My actual project), and the staff all have assigned a number. I want the scheduler to be able to input the current workers, when they can work, what they do, and then Voila! The problem I am having is the part of the actual generator where the proram takes a set and then chooses one integer. Ie. User Input: 1,3,6,7,8,10,12,13,16,17,19,20,32 Generate Code: Choose 8 (For Example) If some ...Show All

• Visual Basic Form show unrequested

  To get some experience using VBE, I converted a simple program I once made for myself(VB5). It's a birthday calendar, using a VB5 commandbutton for each day of the year, i found that VBE has great problems handling this many controls, it is slow, very slow and realy unworkable. Some where else in this forum I found that others with a lot of controls experience the same problems and there is no neat solution for it. In the mid 80's the basicinterpreter was quicker than this VBE with a machine that is 2000 times faster. Another problem I have is that the main(start) form of the program shows up unrequested. In the load section of the (start)form I show another form from which I normally select whether I show the (start)form or not. The se ...Show All
