Remove Filter  | I am trying to figure out how to convert hexadecimal values into mips instructions but I am not having any luck. From my understanding you have to first break the value down to machine level (binary) and then use that result to determine the instruction by converting each section of … |
| | I am trying to find ways to get the hex data from a file opened in a windows form using the open file dialog. I've done some reading and have found that .NET Framework used to have a byte viewer component built into System.Design that was a quick standard way … |
| | I realized that I haven't released any snippets in a while so I figured while I was working on some interesting projects of my own that I would release one that I recently decided to write because I don't see the algorithm out there in C# very often. This snippet … |
| | Okay so I know how to close the application completely but when I have multiple forms it tends to mess up my main form and cause bugs when I close my secondary forms. Can anyone help me with this problem? [CODE]// The bug I get is in Program.cs and it …  |
| | The snippet provided will cover the basics of an on screen keyboard; the only things it doesn't have are numbers, symbols, and extra keys. This will give you the fundementals to build off of. It's written using Microsoft's XNA Framework, however it should be fairly simple to port over to … |
| | These are just some of the more useful #define statements I've used in C++. These are some of the statements you'll use the most (in the case of template<typename T> when you use it, you use it a lot!). So I figured I'd post it for others, even though a … |
| | I've been given a homework assignment in which I have to create a linked list, then store 25 random integers within it, after I've stored the values I have to find the sum of these 25 numbers, and then the floating point average of them. So for the most part … |
| | I'm trying to convert a number to a string then back to a number to perform math, then back to a string to return it to the user. I don't understand the problem because this is how my friend did it (that I can remember and it worked for him). …  |
| | I'm out of practice on my C++ and have kind of picked up a new hobby; it turns out that I like creating electronic devices. Particularly amplifiers and sound to light kits. Stuff like that; the problem is that determining the amount of resistance a resistor on an old creation … |
| | It's been a while since I've posted anything; I've been really busy. I was just sworn into the Marine Corps, and just finished making my own 5x5x5 LED cube. Now I'm wanting to get a little programatical with what I did in the real world. Basically I'm needing to find … |
| | Just a couple basic static mathematical helper methods that I've found useful for game development. Feel free to add some in replies for future visitors. I will do another post later this week with advanced helper methods from trig and calc. I will also do a geometry helper class as … |
| | I think this is the first actual discussion thread of code on a coder's website I've actually ever seen, and I'm the one posting it. (HA!) So basically; I got bored and found a website called Project Euler. It has a bunch of "mathematical" problems to solve. Eight pages and …  |
| | Figured I've been working on material for a while and would throw these up for everyone that needs them in the future to use. It's very simple implementation; if I get enough people asking me to, I will write the methods for each of the instructions so you don't have … |
| | I had a small problem with collision detection starting out with XNA 4.0 so I figured I'd release a simple snippet that helps with two different types of collision detection; Per-Pixel and Rectangular. To use simply copy and paste the snippet into your current source, or you could put it … |
| | I'm trying to upgrade my class library to my current mathematical skill set and am having trouble with multi-term polynomials, especially those I where I don't know how many terms the user will be putting in. I know that the formula for the first derivative of a polynomial is ax^n … |

| | I'm having trouble with my some output in hexadecimal math. The subtraction overload seems to work fine, but when I add an address to another it goes all wierd on me. :( Here is a sample output: 00000000 + 0000055c = 0000000c // Incorrect 000a0000 + 00000180 = 000a000000000080 // … |
| | I get tired of having to google this simple line of code all the time. My problem with memorizing it is that I switch back and forth between C# and C++ all the time, and the way you overload operators in each is different. So once I learn one again, … |
| | I realize I haven't released anything in a while so I figure I'll just type a basic set of things for you all to use or learn from. All of the following requires XNA Framework, but can be easily ported over to .NET Framework for use with forms applications. The … |
| | I'm having trouble calculating the Nth root of a given value. I don't understand what's going wrong in the algorithm, but the values are incredibly close. Only off by about 0.78891 for small values, and about 0.52 for larger ones. So any help with this is appreciated; I don't want … |
| | I'm not sure if I remember how to do the Quadratic Formula because I haven't had to use it since I learned about it back in '05. So I did a little research on how the formula works and from what I understand the formula is: [code] // -b +- … |
| | I'm wondering how to make my custom user type able to be added and subtracted from the same types. For example: [code]public class CustomType { public float x; public float y; public CustomType(float x, float y) { this.x = x; this.y = y; } } public class test : Form … |
| | Okay basically I have a class that manages sound and it's volume is a floating point value with 1.00f being 100% and 0.00f being 0%. So the math is done in low values. Allowing more precise calculations. Anyways, I'm adding and subtracting from the value by 0.05f as per the … |
| | My project for my C++ class is to develop an application that will help me out in my programming life, and since I constantly have to use a calculator to determine the values in free fall acceleration I decided to write an application to do it for me. I was …  |

| | If I remember correctly from C# to C++ the following should convert into the second following. I need to create a console application that will output the physical address of the main interface on a user's computer. This in my experience seems to always be the second interface in the … |
| | Okay, so I've used this without even knowing 100% about what it is. I know what it does so I've always just called it the "type of object" but I want to know what this is really called. For example, I create a class and I want it to be … |
| | I haven't tested this yet but it should work. The implementation is fairly simple. I don't have my laptop so I can debug the code at the present time. This basically increments the frame count everytime the game draws itself (allowing us to calculate frames per second considering the draw … |
| | I used a label inside my snippet just to test it; but this will simply increment and decrement a float value by 0.2f between the values specified in the conditionals. I have it updating between 8f and 15f. Must be run on a timer (make sure the interval is low … |
| | I'm trying to make my particles fade in my application using the alpha argument of the Color.FromArgb method but my math won't work because I have a nullable DateTime variable and the error it gives me is 'System.Nullable<System.TimeSpan>' does not contain a definition for 'TotalMilliseconds' and no extension method 'TotalMilliseconds' … |
| | There only two glitches within this code that I can't seem to get 100% spot on. However, this will create a functioning menu (text based) on your form at runtime. I plan to develop an actual control exactly like it. It uses a custom class I developed called LocationBounceEffect that … |
| | I've recently posted a code snippet of a working 2D text menu for Windows Forms Applications. However, as I was going through and revising this snippet (trying to make it better and add functionality to it) I've created two new problems. The first problem is that my text is not … |
| | XNA Game Studio is not required to use this functionality. This example is very basic, and I typed it up because I was bored. It does not contain functionality for navigation through the menu, but it will display the menu as it should at the specified location. Please enjoy it, … |
| | I've been trying to better my lesser side of knowledge in the C# programming language by tackling graphics head on. I've learned a little bit, but I'm getting stumped right now because I can't explain 100% what's going on here. I've developed a Pong game to teach myself how to … |
| | I'm trying to convert my C# class library over to C++ and was wondering if this is how scientific notation should look. Any pointers would be nice. [code]// Scientific Notation? private int i = 0; private string Sign = ""; public string Output = ""; public void Sci(double x) { …  |

| | I don't even know where to begin with this one, but I'm wanting to create a couple graphic controls that at least appear to be in 3D (not stereoscopic but as in not a 2D flat image) and can rotate and move back and forth on an illusional Z axis. …  |
| | I'm trying to get some developer tools for my Macintosh Mini running on Power PC. It's OS is Mac OS X Leopard. I've tried getting Xcode but I can't find any downloads for it that don't require the developer programs at Apple's website. If anyone has any ideas or any … |
| | I'm trying to create a custom control that has about 20 labels on it, I want to make the fore-color of these labels read-only, and make them change with the fore color of the control instead of all individually. The same with the back color. I also need to know … |
| | This release is an updated version of my previously released code snippet entitled "Get Internet Connection State". I've made this snippet into an actual control that you can add to your toolbox. It can be used with all versions of Visual Studio C#. I'm also posting the main source code, … |
| | I've developed a code that is intended to be used in an application extension (as with all my codes) that will tell you if the current computer has an internet connection. To use just include the namespace given at the top of the snippet, then the connection state is a … |
| | I'm trying to incorporate my custom control called "windmill" into my application extension. I've created a few properties that I want to be visible in the properties window and when I built my project and tried to use it in a test project it did not work. To top it … |
| | I was just washing dishes and as usual was pondering programming scenarios. One came across my mind that hit me hard. UPDATES! I would like links to information on how to make an application that checks for updates at a location on a free website (I'm using webs.com for my … |
| | I've been google searching this for a while but can't seem to find information on it that is helpful to me. Is it a way to work with partners on projects over a server? If so then this would be lovely. I get tired of sending my projects to friends … |
| | I'm trying to learn how to create plugins, the only problem is my friend only knows .NET, I know C# and can partially read .NET. Is there anyone in this section that can convert this all over to C# for me so I can truly study it? [code]Public Interface IPlugin … |
| | I'm having trouble getting intellisense to show my summaries of my methods and variables. I have a DLL that I will be releasing to my developer team soon and without the intellisense working they won't know 100% what everything is for. They will just have a simple hint from the …  |
| | As the title states I'm building a calculator. I've got two arrays, one for holding the values input by the user, and the other for holding the operators. Addition seems to work just fine, however subtraction, multiplication, and division are still putting up a fight. I believe it's just logic … |
| | I'm trying to create a struct for an 8 bit signed integer, seeing as how I'm creating a calculator it would be useful. Windows' calc.exe has this set up as precision for Qword, Dword, Word, and Bytes. I have 64, 32, and 16 because they're already programmed into Visual C#. …  |
