In Windows, you can execute the net stats srv command, and in Unix, you can execute the uptime command. Each output must be parsed to acquire the uptime. This method automatically executes the necessary command by detecting the user’s operating system. Note that neither operation returns uptime in millisecond precision. public static long getSystemUptime() throws … Read more
If the matrix A has more rows than columns, then you should use least squares fit. If the matrix A has fewer rows than columns, then you should perform singular value decomposition. Each algorithm does the best it can to give you a solution by using assumptions. Here’s a link that shows how to use … Read more
We experienced the same Problem with Java 7 Update 45 (1.7.0_45). The JNLP Spec gave a hint for a work-around: Properties set in the jnlp file will normally be set by Java Web Start after the VM is started but before the application is invoked. Some properties are considered “secure” properties and can be passed … Read more
From Perlfaq8: You’re confusing the purpose of system() and backticks (“). system() runs a command and returns exit status information (as a 16 bit value: the low 7 bits are the signal the process died from, if any, and the high 8 bits are the actual exit value). Backticks (“) run a command and return … Read more
Maybe the easiest way is. Get the DeviceId Nuget package And use it like string deviceId = new DeviceIdBuilder() .AddMachineName() .AddMacAddress() .AddProcessorId() .AddMotherboardSerialNumber() .ToString(); You can personalize the info used to generate the ID Github Project
If you wanted to stick with the strings something like this would work… TreeNode root = new TreeNode(); TreeNode node = root; treeView1.Nodes.Add(root); foreach (string filePath in myList) // myList is your list of paths { node = root; foreach (string pathBits in filePath.Split(“https://stackoverflow.com/”)) { node = AddNode(node, pathBits); } } private TreeNode AddNode(TreeNode node, … Read more
Seems that if you can’t use java.awt.Desktop you have to distinguish between the OSes: Windows: RUNDLL32.EXE SHELL32.DLL,OpenAs_RunDLL <file.ext> Linux: edit <file.ext> Mac: open <file.ext> HTH. Obviously, that is not very portable…
Best way to answer is with an example: #include <sys/time.h> #include <stdlib.h> #include <stdio.h> #include <math.h> /* Return 1 if the difference is negative, otherwise 0. */ int timeval_subtract(struct timeval *result, struct timeval *t2, struct timeval *t1) { long int diff = (t2->tv_usec + 1000000 * t2->tv_sec) – (t1->tv_usec + 1000000 * t1->tv_sec); result->tv_sec = … Read more
The Windows XP systeminfo command displays lots of stuff, but the relevant information is this: System Locale: en-us;English (United States) Input Locale: en-us;English (United States) To get equivalent information in Java, use Locale.getDefault() to get the Locale that Java is using, and use methods on the Locale object such as getCountry(), getLanguage() to get details. … Read more
