  • powershell indentation

    - by Steve B
    I'm writing a large script that deploys an application. This script is based on several nested functions call. Is there any way to "ident" the output based on the depth ? For example, I have : function myFn() { Write-Host "Start of myfn" myFnNested() Write-Host "End of myfn" } function myFnNested() { Write-Host "Start of myFnNested" Write-Host "End of myFnNested" } Write-Host "Start of myscript" Write-Host "End of myscript" The output of the script will be : Start of myscript Start of myfn Start of myfnNested End of myFnNested End of myFn End of myscript What I want to achieve is this output : Start of myscript Start of myfn Start of myfnNested End of myFnNested End of myFn End of myscript As I don't want to hardly code the number of spaces (since I does not know the depth level in complex script), how can I simply reach my goal ? Maybe something like this ? function myFn() { Indent() Write-Host "Start of myfn" myFnNested() Write-Host "End of myfn" UnIndent() } function myFnNested() { Indent() Write-Host "Start of myFnNested" Write-Host "End of myFnNested" UnIndent() } Write-Host "Start of myscript" Write-Host "End of myscript"

  • Automatically make or update a copy real-time on another hard drive volume whenever files are saved to a particular folder

    - by mrblint
    Whenever I save or update a file to a particular designated folder on my C:\drive I would like to make or update a copy on my network-attached storage device, ideally saving the copy to the NAS as a version rather than overwriting a copy there, if possible. I have Windows 7 x64 Ultimate. Is there any feature built-in that can accomplish this? It has to be a real copy, not merely a pointer. I'm trying to achieve some redundancy for especially critical documents (in a variety of formats) that change frequently throughout the day. P.S. I am looking for folder-level granularity; I wouldn't want this to happen for every file on the C: volume.

  • What happened to 'Copy Public Gallery Link' for folders in Photos in Dropbox?

    - by Transgenic
    I've been trying to figure out how to use the 'Photos' folder properly, but it does not seem to contain the functionality that is mentioned on various websites. From what I've read, you are supposed to create a folder within the 'Photos' folder. At that point, it becomes a public gallery for which you can access the context menu item Copy Public Gallery Link. However, I do not have this context menu item. I found a topic on the DropBox forum, but it is 2 years old. Even the various website information mentioned is over a year old. I found a topic from this year on SuperUser that mentions about the Share link menu item. I understand that this functionality is basically the same as Copy Public Gallery Link, however, the key difference is that it opens the website for which I need to click 'Copy link to this page' link, which then adds it to the clipboard. My primary questions are: Did they phase out the Copy Public Gallery Link from the context menu entirely? If not, is there a way to re-enable this menu item? If not, am I using the Photos folder properly? Lastly, if there is no way to get this menu item, is there some kind of script or hack-around that will let me simplify the Shark link + Copy link to this page functionality without requiring it to open my web browser? Note: I had to edit my post to remove other website links that I mention since I'm considered a 'New User' here and am only able to post 2 hyperlinks. Sorry.

  • How to know an article is copy from other site? [on hold]

    - by cj333
    We have a site. our main servers is for blogs and freedom write. Our custom can submit their article in our site. But for ptotect the copywrite, we do not allow custom just do easy copy and parse a whole article from other site. At least they should write something by themselves. And how to check if the article is a completed copy from other site? google webmasters? google search api? or other better way? Because we always received DMCA notice by google, so I am tring to stopping the articles before they were posted. Thanks.

  • How to copy or sync music on iphone 3gs on ubuntu 14.04?

    - by user276842
    I’m using Ubuntu 14.04 and want to copy music to/on my iPhone 3gs. I already installed the actual mobile device, but neither Rhythmbox nor gmusicbrowser show my phone. Only on Gigolo I can see it, and transfer data, but the music I copy is not working on my phone.

  • AccessViolationException from a combo: Attempted to read or write protected memory

    - by Sparky
    Users are occassionally getting the above error when using our application (VB.Net, Winforms, using v2 of the framework). I'm not able to reproduce it. The callstack is as follows: : System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Windows.Forms.UnsafeNativeMethods.CallWindowProc(IntPtr wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam) at System.Windows.Forms.NativeWindow.DefWndProc(Message& m) at System.Windows.Forms.Control.DefWndProc(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ComboBox.WndProc(Message& m) at ControlEx.AutoCompleteCombo.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) The code for ControlEx.AutoCompleteCombo.WndProc is as follows: Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message) Try If Not m_fReadOnly Then MyBase.WndProc(m) Else Select Case m.Msg Case WM_LBUTTONDOWN, WM_LBUTTONDBLCLK ' do nothing Case Else MyBase.WndProc(m) End Select End If Catch ex As OutOfMemoryException Throw New OutOfMemoryException("Exception during WndProc for combo " & Me.Name, ex) End Try End Sub The error handling was added so we can determine which combo causes the problem when we get an OutOfMemoryException. Any clues as to what causes this would be muchly appreciated! :-)

  • How to write an iphone application to control a device that exposes a telnet api

    - by MAC
    Hi! I have to write an iphone application that controls a device. This device exposes a telnet based interface. The application should ideally have user access control and customizability for each user. I was thinking of writing C++ classes that would communicate with the device using sockets. This functionality can then be exposed through web-services that can be called by the iphone application. However as i looked into it deeper, the api allows you to register for events using telnet and then you can receive notification when those events occur. That kinda put a spanner in the works for me. I for one dont know a "push" scenario can work with webservices. First off i have never programmed for the iphone so far. So i am not really sure what can be done. So i was thinking if instead of having a webserver to go through, why not have the application independently running on the iphone, directly communicating with the device using sockets. The question though is, is that possible and second i am thinking it would raise a security aspect. First we could control security as everything was going through our central server. Is there a way to handle security (in the sense who has access to the device) without having a central server. I am sorry that this seems like an unorganized post, but iam trying to brainstorm here. Looking forward to hear your opinions.

  • Write binary data as a response in an ASP.NET MVC web control

    - by Lou Franco
    I am trying to get a control that I wrote for ASP.NET to work in an ASP.NET MVC environment. Normally, the control does the normal thing, and that works fine Sometimes it needs to respond by clearing the response, writing an image to the response stream and changing the content type. When you do this, you get an exception "OutputStream is not available when a custom TextWriter is used". If I were a page or controller, I see how I can create custom responses with binary data, but I can't see how to do this from inside a control's render functions. To simplify it -- imagine I want to make a web control that renders to: <img src="pageThatControlIsOn?controlImage"> And I know how to look at incoming requests and recognize query strings that should be routed to the control. Now the control is supposed to respond with a generated image (content-type: image/png -- and the encoded image). In ASP.NET, we: Response.Clear(); Response.OutputStream.Write(thePngData); // this throws in MVC // set the content type, etc Response.End(); How am I supposed to do that in an ASP.NET MVC control?

  • Attempted to read or write protected memory-Sql Compact and .NEt

    - by Jankhana
    I'm using Sql Compact3.5 as my DB with C# .NET . I have a strange problem with my application. I'm running the code in two PC with same configuration except the Sql Compact installed. In one PC where Sql Compact3.5 is not installed I'm getting this strange error: Exception :Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I checked my code and included try catch everywhere. I'm handling Unhandled exception also using this . I am getting this error from a console application which I'm starting from Windows Form. In both the application I've inserted the Unhandled Exception coding and it's getting executed and getting return to the texxt file. But still Microsoft Don't Error Report is getting generated and I get that Dialog box!!! Y still that dialog box is getting generated is the trouble!!! Is there any way to supress that Dialog box??? Y I'm getting this box when I'm handling the exception and it's executing my catch handler??? In another PC where SQL Compact is installed no error I get!!! Any idea y is that so???

  • 'echo' or drop out of 'programming' write HTML then start PHP code again

    - by thecoshman
    For the most part, when I want to display some HTML code to be actually rendered I would use a 'close PHP' tag, write the HTML, then open the PHP again. eg <?php // some php code ?> <p>HTML that I want displayed</p> <?php // more php code ?> But I have seen lots of people who would just use echo instead, so they would have done the above something like <?php // some php code echo("<p>HTML that I want displayed</p>"); // more php code ?> Is their any performance hit for dropping out and back in like that? I would assume not as the PHP engine would have to process the entire file either way. What about when you use the echo function in the way that dose not look like a function, eg echo "<p>HTML that I want displayed</p>" I would hope that this is purely a matter of taste, but I would like to know if I was missing out on something. I personally find the first way preferable (dropping out of PHP then back in) as it helps draw a clear distinction between PHP and HTML and also lets you make use of code highlighting and hinting for your HTML, which is always handy.

  • asyncsocket Write Issue

    - by James
    I am attempting to use asyncsocket to communicate GPS data from a server app on my iPhone to a client app on my macbook. The two devices connect without any problems, and when the first data is sent from the iPhone to the laptop in asyncsocket's didConnectToHost method, the data is sent without hiccup. When I subsequently try to write additional data to the laptop from the locationManager method, however, no data is written. Here is the code: - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { lat = [NSNumber numberWithFloat:newLocation.coordinate.latitude]; [lat retain]; NSLog(@"lat: %1.0f", [lat floatValue]); NSString *msg = [NSString stringWithFormat:@"%1.0f", [lat floatValue]]; NSData *msgData = [msg dataUsingEncoding:NSUTF8StringEncoding]; [listenSocket writeData:msgData withTimeout:-1 tag:0]; } listensocket is my instance of ASyncSocket. I know that no data is being sent because after the initial successful transfer, the didWriteDataWithTag method is not called. Can anyone explain this? Thanks! James

  • Attempted to read or write protected memory

    - by Interfector
    I have a sample ASP.NET MVC 3 web application that is following Jonathan McCracken's Test-Drive Asp.NET MVC (great book , by the way) and I have stumbled upon a problem. Note that I'm using MVCContrib, Rhino and NUnit. [Test] public void ShouldSetLoggedInUserToViewBag() { var todoController = new TodoController(); var builder = new TestControllerBuilder(); builder.InitializeController(todoController); builder.HttpContext.User = new GenericPrincipal(new GenericIdentity("John Doe"), null); Assert.That(todoController.Index().AssertViewRendered().ViewData["UserName"], Is.EqualTo("John Doe")); } The code above always throws this error: System.AccessViolationException : Attempted to read or write protected memory. This is often an indication that other memory is corrupt. The controller action code is the following: [HttpGet] public ActionResult Index() { ViewData.Model = Todo.ThingsToBeDone; ViewBag.UserName = HttpContext.User.Identity.Name; return View(); } From what I have figured out, the app seems to crash because of the two assignements in the controller action. However, I cannot see how there are wrong!? Can anyone help me pinpoint the solution to this problem. Thank you.

  • write to fifo/pipe from shell, with timeout

    - by Tim
    I have a pair of shell programs that talk over a named pipe. The reader creates the pipe when it starts, and removes it when it exits. Sometimes, the writer will attempt to write to the pipe between the time that the reader stops reading and the time that it removes the pipe. reader: while condition; do read data <$PIPE; do_stuff; done writer: echo $data >>$PIPE reader: rm $PIPE when this happens, the writer will hang forever trying to open the pipe for writing. Is there a clean way to give it a timeout, so that it won't stay hung until killed manually? I know I can do #!/bin/sh # timed_write <timeout> <file> <args> # like "echo <args> >> <file>" with a timeout TIMEOUT=$1 shift; FILENAME=$1 shift; PID=$$ (X=0; # don't do "sleep $TIMEOUT", the "kill %1" doesn't kill the sleep while [ "$X" -lt "$TIMEOUT" ]; do sleep 1; X=$(expr $X + 1); done; kill $PID) & echo "$@" >>$FILENAME kill %1 but this is kind of icky. Is there a shell builtin or command to do this more cleanly (without breaking out the C compiler)?

  • Write a sql for updating data based on time

    Hello everyone, Because I am new with SQL Server and T-SQL, so I will need your help. I have 2 table: Realtime and EOD. To understand my question, I give example data for 2 tables: ---Realtime table--- Symbol Date Value ABC 1/3/2009 03:05:01 327 // this day is not existed in EOD -> inserting BBC 1/3/2009 03:05:01 458 // this day is not existed in EOD -> inserting ABC 1/2/2009 03:05:01 326 // this day is new -> updating BBC 1/2/2009 03:05:01 454 // this day is new -> updating ABC 1/2/2009 02:05:01 323 BBC 1/2/2009 02:05:01 453 ABC 1/2/2009 01:05:01 313 BBC 1/2/2009 01:05:01 423 ---EOD table--- Symbol Date Value ABC 1/2/2009 02:05:01 323 BBC 1/2/2009 02:05:01 453 I will need to create a store procedure to update value of symbols.

  • php fopen function dies, though I have file permissions set to read and write

    - by Matthew Robert Keable
    I'm following a tutorial on php, and am having difficulty getting this to work. I set the appropriate directory permissions to read and write, but every time I run this, I get the die string. The code is: $ourFileName = "testFile.txt"; $ourFileHandle = fopen($ourFileName, 'w') or die("can't open file"); fclose($ourFileHandle); As far as my basic understanding goes, if "testFile.txt" does not exist, fopen should create that file (I have basic knowledge of Python, and remember this same principle in that language). But it...it doesn't. Even if I create the aforementioned file, and put it up, that line of code still returns a die string. My hosting account does not give me permission to execute. Is this a problem? My server runs on Windows. I am using Dreamweaver CS5, on OSX 10.5.8. I've done some searching on this, and see other people having similar issues - but none of them keyed to exactly my range of problems. Being that I'm a beginner, I feel that it might be something I'm overlooking. Thanks!!

  • How to write Java-like enums in C++ ?

    - by Rahul G
    Coming from Java background, I find C++'s enums very lame. I wanted to know how to write Java-like enums (the ones in which the enum values are objects, and can have attributes and methods) in C++. As an example, translate the following Java code (a part of it, sufficient to demonstrate the technique) to C++ : public enum Planet { MERCURY (3.303e+23, 2.4397e6), VENUS (4.869e+24, 6.0518e6), EARTH (5.976e+24, 6.37814e6), MARS (6.421e+23, 3.3972e6), JUPITER (1.9e+27, 7.1492e7), SATURN (5.688e+26, 6.0268e7), URANUS (8.686e+25, 2.5559e7), NEPTUNE (1.024e+26, 2.4746e7); private final double mass; // in kilograms private final double radius; // in meters Planet(double mass, double radius) { this.mass = mass; this.radius = radius; } private double mass() { return mass; } private double radius() { return radius; } // universal gravitational constant (m3 kg-1 s-2) public static final double G = 6.67300E-11; double surfaceGravity() { return G * mass / (radius * radius); } double surfaceWeight(double otherMass) { return otherMass * surfaceGravity(); } public static void main(String[] args) { if (args.length != 1) { System.err.println("Usage: java Planet <earth_weight>"); System.exit(-1); } double earthWeight = Double.parseDouble(args[0]); double mass = earthWeight/EARTH.surfaceGravity(); for (Planet p : Planet.values()) System.out.printf("Your weight on %s is %f%n", p, p.surfaceWeight(mass)); } } Any hep would be greatly appreciated!

  • How to write a good PHP database insert using an associative array

    - by Tom
    In PHP, I want to insert into a database using data contained in a associative array of field/value pairs. Example: $_fields = array('field1'=>'value1','field2'=>'value2','field3'=>'value3'); The resulting SQL insert should look as follows: INSERT INTO table (field1,field2,field3) VALUES ('value1','value2','value3'); I have come up with the following PHP one-liner: mysql_query("INSERT INTO table (".implode(',',array_keys($_fields)).") VALUES (".implode(',',array_values($_fields)).")"); It separates the keys and values of the the associative array and implodes to generate a comma-separated string . The problem is that it does not escape or quote the values that were inserted into the database. To illustrate the danger, Imagine if $_fields contained the following: $_fields = array('field1'=>"naustyvalue); drop table members; --"); The following SQL would be generated: INSERT INTO table (field1) VALUES (naustyvalue); drop table members; --; Luckily, multiple queries are not supported, nevertheless quoting and escaping are essential to prevent SQL injection vulnerabilities. How do you write your PHP Mysql Inserts? Note: PDO or mysqli prepared queries aren't currently an option for me because the codebase already uses mysql extensively - a change is planned but it'd take alot of resources to convert?

  • BASH echo write mysql input

    - by jmituzas
    Have a bash menu where variables write to file for mysql input. heres what I have: echo "CREATE DATABASE '$mysqldbn'; #GRANT ALL PRIVILEGES ON *.* TO '$mysqlu'@'$myhost' IDENTIFIED BY '$mysqlup' WITH GRANT OPTION; GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON '$mysqldbn'.* TO '$mysqlu'@'$myhost' IDENTIFIED BY '$mysqlup'; GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON '$mysqldbn'.* TO '$mysqlu'@'$myip' IDENTIFIED BY '$mysqlup'; GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON '$mysqldbn'.* TO '$mysqlu'@'localhost' IDENTIFIED BY '$mysqlup'; GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES< LOCK TABLES on '$mysqldbn'.* TO '$mysqlu'@'$rip' IDENTIFIED BY '$mysqlup';" > nmysql.db mysql -u root -p$mypass < nmysql.db problem is to get variables to show I had to put them in single quotes, the single quotes show up as I want for instances like '$mysqlu'@'localhost'. But how can I remove the quotes and still get to use the variable in the instance like, CREATE DATABASE '$mysqldbn' ? Double quotes wont work either, I am at a loss. Thanks in advance, Joe
