![]() Within the loop, perform another loop to iterate over each byte of the binary data that corresponds to the current character in the product key.Use a loop to iterate over each character in the product key.Create an empty string variable named keyString.Create an array of characters named ke圜hars, which contains the valid characters that can be used in a Windows product key.Set the keyLength variable to 25, which is the number of characters in the product key.Set the keyOffset variable to 52, which is the offset in the binary data where the product key is located.Create a new MemoryBlock object to store the product key data.The algorithm used to extract the product key from the binary data involves the following steps: Return the extracted product key as a string.Extract the product key from the binary data using a complex algorithm.Retrieve the binary data associated with the “DigitalProductId” value of this registry key, which contains the product key for Windows.This key contains information about the currently installed version of Windows. Create a new instance of a RegistryItem object that points to the “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion” key in the Windows registry.The GetWindowsSerialKey function retrieves the product key for the currently installed version of Windows. Var formattedString as String = FormatStringWithHyphens(myString) Convert the outputString array back to a single string using the String.FromArray method.Įxample usage var myString as String = "123456789".Repeat steps 4-7 for each character in the inputString array.If it is, and if we have not yet reached the last character in the inputString array, add a hyphen to the outputString array.Check if charCount is divisible by 5 (i.e., if this is the 5th character being processed).Add the current character to the outputString array.Use a loop to iterate over each character in the inputString array.Split the input string into individual characters and store them in the inputString array.Define two string arrays named inputString and outputString, and initialize the charCount variable to 0.The purpose of this function is to add hyphens after every fifth character in the input string. The FormatStringWithHyphens function takes in a single input parameter, a string named input, and returns a string value. (Functions located at the end of the tutorial) FormatStringWithHyphens Function ![]() Paul learned to program in BASIC at age 13 and has programmed in more languages than he remembers, with Xojo being an obvious favorite.In this tutorial, we will explore two Xojo functions: FormatStringWithHyphens and GetWindowsSerialKey. You might want to try having multiple rotating cubes at once. ![]() A timer adjusts the values for the rotations and translation, telling the cube to re-render itself.ĭownload the project and play around with it. The code does some initialization, scales things to half the size of the viewable area, applies rotations and a translation to get the cube to move about and then draws the cube. The main code for this is in the DrawCube() method that is called by the Render event of the OpenGLSurface: OpenGL.glClear(OpenGL.GL_COLOR_BUFFER_BIT Or OpenGL.GL_DEPTH_BUFFER_BIT) I found a tutorial on creating a rotating cube and with some minor help from StackOverflow, tweaked it to display a rotating cube that moves around in a mesmerizing way. This means you can often use OpenGL tutorials on the internet with Xojo with almost no code changes. Xojo’s implementation of OpenGL maps directly to the OpenGL API. ![]()
