  • C# code simple console program not working

    - by Wast334
    I am trying to test some console ability in C#.. I can't get this code to work using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Dim myMessage; myMessage = @"Hello World"; printf(@"%@", myMessage); return 0; } } } I am getting a bunch of compiler errors i am not sure what I am doing wrong..?

  • Single console in eclipse for both Server and Client

    - by rits
    I am building a client server application using Java Sockets (in Windows XP). For that I need different consoles for both Client and Server(for Input and Output operations). But in eclipse both share a single console. Is there any plugin or some sort of cheat through which I can do this. After googling I got this, http://dev.eclipse.org/newslists/news.eclipse.newcomer/msg17138.html But, this seems to be only for write operations, not read operations. Also, I tried the following to launch application manually, but even this is not working........ package mypack; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException; import java.io.OutputStream; import java.io.PrintStream; public class MySystem { public static void changeStream(String mainFile) throws IOException{ File temp = new File(".") ; String parentPath = temp.getCanonicalPath() ; System.out.println(parentPath); //creation of batch file starts here try{ File f = new File(parentPath + "\\a.bat") ; System.out.println("Created : " + f.createNewFile()); //f.deleteOnExit() ; FileOutputStream fos = new FileOutputStream(f) ; String str = "java " + mainFile ; String batchCommand="@echo off\n"+str+"\npause\nexit"; char arr[] = batchCommand.toCharArray() ; System.out.println(str) ; for(int i = 0 ; i < arr.length ; i++){ fos.write(arr[i]) ; } fos.close() ; } catch(Exception e){ } //creation of batch file ends here //execution of batch file starts here try{ Runtime r = Runtime.getRuntime() ; System.out.println(parentPath + "\\a.bat") ; Process p = r.exec(new String[]{"cmd","/k","start a.bat"},null,new File(parentPath)) ; OutputStream os = (OutputStream)p.getOutputStream() ; System.setOut( new PrintStream(os) ) ; System.out.println("Hello"); } catch(Exception e){ e.printStackTrace(); } //execution of batch file ends here } public static void main(String[] args) throws IOException { MySystem.changeStream("MySystem") ; } }

  • How do I dynamically import a module in App Engine?

    - by Scott Ferguson
    I'm trying to dynamically load a class from a specific module (called 'commands') and the code runs totally cool on my local setup running from a local Django server. This bombs out though when I deploy to Google App Engine. I've tried adding the commands module's parent module to the import as well with no avail (on either setup in that case). Here's the code: mod = __import__('commands.%s' % command, globals(), locals(), [command]) return getattr(mod, command) App Engine just throws an ImportError whenever it hits this. And the clarify, it doesn't bomb out on the commands module. If I have a command like 'commands.cat' it can't find 'cat'.

  • App pool gets stuck on reset and takes .net pages out

    - by delenda
    Several times after our app pool has been told to reset, it gets stuck, the .net pages go down and the following error appears in the application event log: Failed to execute request because the App-Domain could not be created. Error: 0x80070057 The parameter is incorrect. Our app pool is scheduled to automatically reset at 4am, so the errors stay up until we manually restart the app pool. Has anyone else encountered the error or know of any solutions? Research has suggested it's a permissions issue, but the permissions don't change and the error happens infrequently. The site has no other permission based problems and the app pool identity has permission where needed.

  • App-V Problems After SCCM 2007 SP2 Upgrade

    - by GAThrawn
    We're running an SCCM (MS System Centre Config Manager, successor to SMS) 2007 environment and delivering a number of applications to clients virtualized using App-V 4.5.1. The App-V apps are delivered by SCCM in Download-and-Execute, not streaming mode. The SCCM environment was recently service packed to SCCM 2007 SP2 (amongst other things this gives Win7 support). We also pushed out the updated SCCM clients to our workstations. This seems to have broken file associations for virtual apps for a large number of our users. The users can still open their App-V apps by finding the specific app on their Start Menu and clicking it's icon, but double-clicking an associated file in Explorer, or opening an email attachment gives the "This action is only valid for installed applications" error. There is a Technet blog entry from the App-V team talking about this issue "Upgrade to ConfigMgr 2007 SP2 may break App-V File Type Associations" but running the script there comes back saying "The User Interface option has been updated" but hasn't seemed to fix the problems for any of our users. Unfortunately the Technet blogs don't seem to have comments switched on so you can't see how this has worked out for other people. Anyone else had this problem, have you found any other way to fix it?

  • Overloading Console.ReadLine possible? (or any static class method)

    - by comecme
    I'm trying to create an overload of the System.Console.ReadLine() method that will take a string argument. My intention basically is to be able to write string s = Console.ReadLine("Please enter a number: "); in stead of Console.Write("Please enter a number: "); string s = Console.ReadLine(); I don't think it is possible to overload Console.ReadLine itself, so I tried implementing an inherited class, like this: public static class MyConsole : System.Console { public static string ReadLine(string s) { Write(s); return ReadLine(); } } That doesn't work though, cause it is not possible to inherit from System.Console (because it is a static class which automatically makes is a sealed class). Does it make sense what I'm trying to do here? Or is it never a good idea to want to overload something from a static class?

  • most reliable linux terminal app / general procedures for process stability

    - by intuited
    I've been using konsole (KDE 4.2) for a while now but it crashed recently. Konsole is efficiently designed to use one instance for all of the windows for your entire X session. Extra-unfortunately, because of this ingenuity the crash brought down all the humpty-dumptys and their bashes and their bashes' applications and all the begattens' begattens all the way down to Jebodiah Springfield into one big flat nonexistent omelette. The fact that this app is capable of crashing under any circumstances is pretty disappointing. Although KDE 4.2 is not expected to be entirely stable -- and yes, I know, I should update my distro -- it's still a no-sell for me, since if at all possible, this sort of thing Shouldn't Happen to something that's likely to be a foundation for an entire working environment. Maybe this is arrogant and unrealistic, but if it's possible to have something more stable, I want it. So other than running under screen -- which is fun, nifty, and thus far flawless in its reliability, but which has some issues with not understanding certain keycodes -- I'm looking for ways to improve my environment's reliability. The most obvious strategy is to cast about for a more reliable console app. A standard featureset -- which to me includes tabbed windows, Unicode support, and a decent level of keyboard shortcut configuration -- is pretty much essential. I'm currently running gnome-terminal and roxterm, both of which have acceptable featuresets (pretty much identical, actually; I think rox is actually the superset), and neither of which have provided me with extensive, objective reliability data. Not that they were expected to. Other strategies are also welcome. Were I responding to this question I would perhaps suggest backgrounding critical tasks with & and/or disowning them so they don't come down with the global pandemic. And stuff like that.

  • MySQL Utility Users' Console Oerview

    - by rudrap
    MySQL Utility Users' Console (mysqluc): The MySQL Utilities Users' Console is designed to make using the utilities easier via a dedicated console. It helps us to use the utilities without worrying about the python and utility paths. Why do we need a special console? - It does provide a unique shell environment with command completion, help for each utility, user defined variables, and type completion for options. - You no longer have to type out the entire name of the utility. - You don't need to remember the name of a database utility you want to use. - You can define variables and reuse them in your utility commands. - It is possible to run utility command along with mysqluc and come out of the mysqluc console. Console commands: mysqluc> help Command Description ----------------------           --------------------------------------------------- help utilities                     Display list of all utilities supported. help <utility>                  Display help for a specific utility. help or help commands   Show this list. exit or quit                       Exit the console. set <variable>=<value>  Store a variable for recall in commands. show options                   Display list of options specified by the user on launch. show variables                 Display list of variables. <ENTER>                       Press ENTER to execute command. <ESCAPE>                     Press ESCAPE to clear the command entry. <DOWN>                       Press DOWN to retrieve the previous command. <UP>                               Press UP to retrieve the next command in history. <TAB>                            Press TAB for type completion of utility, option,or variable names. <TAB><TAB>                Press TAB twice for list of matching type completion (context sensitive). How do I use it? Pre-requisites: - Download the latest version of MySQL Workbench. - Mysql Servers are running. - Your Pythonpath is set. (e.g. Export PYTHONPATH=/...../mysql-utilities/) Check the Version of mysqluc Utility: /usr/bin/python mysqluc.py –version It should display something like this MySQL Utilities mysqluc.py version 1.1.0 - MySQL Workbench Distribution 5.2.44 Copyright (c) 2010, 2012 Oracle and/or its affiliates.

  • iPhone In-App Purchase Store Kit error -1003 "Cannot connect to iTunes Store"

    - by Rei
    Hi all- I've been working on adding in-app purchases and was able to create and test in-app purchases using Store Kit (yay!). During testing, I exercised my app in a way which caused the app to crash mid purchase (so I guess the normal cycle of receiving paymentQueue:updatedTransactions and calling finishTransaction was interrupted). Now I am unable to successfully complete any transactions and instead am getting only transactions with transactionState SKPaymentTransactionStateFailed when paymentQueue:updatedTransactions is called. The transaction.error.code is -1003 and the transaction.error.localizedDescription is "Cannot connect to iTunes Store"! I have tried removing all products from iTunesConnect, and rebuilt them using different identifiers but that did not help. I have also tried using the App Store app to really connect to the real App Store and download some apps so I do have connectivity. Finally, I have visited the Settings:Store app to make sure I am signed out of my normal app store account. Any ideas? -Rei

  • cscript - print output on same line on console?

    If I have a cscript that outputs lines tothe screen, how do I avoid the "line feed" after each print? Example: for a = 1 to 10 print "." REM (do something) next The expected output should be: .......... Not: . . . . . . . . . . In the past I've used to print the "up arrow character" ASCII code. Can this be done in cscript?

  • ObjectDisposedException when outputting to console

    - by Sarah Vessels
    If I have the following code, I have no runtime or compilation problems: if (ConsoleAppBase.NORMAL_EXIT_CODE == code) { StdOut.WriteLine(msg); } else { StdErr.WriteLine(msg); } However, in trying to make this more concise, I switched to the following code: (ConsoleAppBase.NORMAL_EXIT_CODE == code ? StdOut : StdErr ).WriteLine(msg); When I have this code, I get the following exception at runtime: System.ObjectDisposedException: Cannot write to a closed TextWriter Can you explain why this happens? Can I avoid it and have more concise code like I wanted?

  • get pure text form odt file in console

    - by naugtur
    I am looking for a small linux tool that would be able to extract text from odt file. It just needs to be human-readable and it can have problems with complicated objects etc. It's almost a duplicate of this question but I need it to be small and have no dependencies on OpenOffice or X server I remember having a 1MB MS-DOS program that could render .doc files quite readibly (with some weird markup getting through from time to time), so i expect it to be possible in the linux world too ;)

  • How to tell if leaving iOS app entered foreground from fast-app switching or manually?

    - by JPK
    Is there a way to tell if an iOS app enters the foreground from fast-app switching or manually? I need to know by the time applicationWillEnterForeground is called, so some specific code can be executed (or not executed) depending on the condition in which the app entered the foreground. EDIT: It turned out that this was more of a design issue for me. I moved my code to applicationDidBecomeActive. I also added a BOOL property to the appDelegate called fastAppSwitching (probably the wrong name for it). I set this to YES in application:handleOpenURL and application:openURL:sourceApplication:annotation. Then I added the following code to application:didFinishLaunchingWithOptions: if (launchOptions) { self.fastAppSwitching = YES; } else { self.fastAppSwitching = NO; } In applicationDidBecomeActive, I used the following code: if (fastAppSwitching == YES) { self.fastAppSwitching = NO; //stop, don't go any further } else { ... } EDIT2: MaxGabriel makes a good point below: "Just a warning to others taking the solution described here, applicationDidBecomeActive: is called when the user e.g. ignores a phone call or text message, unlike applicationWillEnterForeground". This is actually also true for in-app purchases and Facebook in-app authorization (new in iOS 6). So, with some further testing, this is the current solution: Add a new Bool called passedThroughWillEnterForeground. In applicationWillResignActive: self.passedThroughWillEnterForeground = NO; In applicationDidEnterBackground: self.passedThroughWillEnterForeground = NO; In applicationWillEnterForeground: self.passedThroughWillEnterForeground = YES; In applicationDidBecomeActive: if (passedThroughWillEnterForeground) { //we are NOT returning from 6.0 (in-app) authorization dialog or in-app purchase dialog, etc //do nothing with this BOOL - just reset it self.passedThroughWillEnterForeground = NO; } else { //we ARE returning from 6.0 (in-app) authorization dialog or in-app purchase dialog - IE //This is the same as fast-app switching in our book, so let's keep it simple and use this to set that self.fastAppSwitching = YES; } if (fastAppSwitching == YES) { self.fastAppSwitching = NO; } else { ... } EDIT3: I think we also need a bool to tell if app was launched from terminated.

  • Creating an app pool a month to limit the scope of issues

    - by user39550
    I have about 360 sites running on a single app pool. Now I know we have a coding issue with one of those sites, were we have accidentally coded a memory leak. So what happens is the site runs, the memory leak starts and soon the app pool runs out of memory. Then slowly but surely, the rest of the 360 sites start going down like a domino affect. I understand that the root of the problem is some bad coding, which we'll fix, but instead of bringing down said 360 sites, I was thinking, we could create a new app-pool monthly that every site we create would go into that months app pool. First, that limit the scope of the issues to 5 - 20 sites and second if one site started having issues we wouldn't be bringing down all 360 sites. Is there any issues to this thinking, possible ramifications? Thanks in Advance! Jeremiah

  • can symbolic links be used within App-V packages

    - by user765827
    We use the stats package SPSS through App-V however although it allows use of custom dialogs and macros, these must be placed in a sub folder within the app installation and so this means that users cannot add new macros. Is it possible to have an App-V package include a symbolically linked folder to point to a different place so that this remote folder could be updated easily without necessitating a rebuild and redeployment of the package? Thanks

  • What is the best plan to handle server fault for google app engine [closed]

    - by lucemia
    I used google-appengine without preparing much backup plans before, but it looks like not a good idea anymore.... Since google app engine is quite hard to find a backup replacement, I plan to just add a "server error" page which will show while server fault. Currently I am thinking to: Use the cdn cloudfare in front of google app engine. It will also handle the NAME server for me. Prepare some static version of webpages (such as "Oops! the server fault") in another hosting platform While google app engine failed, I will switch the destination from google app engine to the static page by change the CNAME records on cloudfare. Is there any other recommand way to solve this situation?
