  • Pass quoted argument string to Start-Process in PowerShell

    - by Luke Puplett
    Hello I'm trying to very simply run an executable and pass a file path in as the first argument. In DOS, this would be the command: import.exe "C:\Some Path\With\Spaces.txt" By placing the path in quotes, the path is correctly parsed as the first token into the executable. In PowerShell I'm using this: $feeds = dir 'T:\Documents\Company\Product Development\Data foreach ($feed in $feeds) { start -FilePath import.exe -ArgumentList $feed.FullName } The problem with the Start-Process cmdlet in PowerShell is that it uses a string array for arguments, so the path is broken up and sent to the executable as separate tokens. Quotes in PowerShell force $feed.FullName to be treated literally. Double quotes "" make PowerShell not see anything in the argument list. "The argument is null or empty." it tells me. I expect that this is a known headache and has had a known workaround from day one. Thanks Luke

  • How is spin lock implemented under the hood?

    - by httpinterpret
    This is a lock that can be held by only one thread of execution at a time. An attempt to acquire the lock by another thread of execution makes the latter loop until the lock is released. How does it handle the case when two threads try to acquire the lock exactly the same time? I think this question also applies to various of other mutex implementation.

  • How to use WatiN to control browser tabs?

    - by Dmitri Nesteruk
    I want to use WatiN with IE in a parallel setting, i.e. work with dozens/hundreds of pages at once. I've tried sticking it into a Parallel.For loop only to see the whole thing crash, so I'm thinking opening multiple tabs in the browser is the way to go. Can someone suggest how this can be done using WatiN (or just some IE-related API) or whether there's a better way? TIA!

  • slicing behaviour question of a list of lists

    - by Lex
    I got a function like def f(): ... ... return [list1, list2] this returns a list of lists [[list1.item1,list1.item2,...],[list2.item1,list2.item2,...]] now when I do the following: for i in range(0,2):print f()[i][0:10] it works and print the lists sliced but if i do print f()[0:2][0:10] then it prints the lists ignoring the [0:10] slicing. Is there any way to make the second form work or do I have to loop every time to get the desired result?

  • Help organising controllers logically

    - by kenny99
    Hi guys, I'm working on a site which i'm developing using an MVC structure. My models will represent all of data in the site, but i'm struggling a bit to decide on a good controller structure. The site will allow users to login/register and see personal data on a number of pages, but also still have access to public pages, e.g FAQs, Contact page etc. This is what I have at the moment... A Template Controller which handles main template display. The basic template for the site will remain the same whether or not you are logged in. A main Website Controller which extends the Template Controller and handles basic authentication. If the user is logged in, a User::control_panel() method is called from the constructor and this builds the control panel which will be present throughout the authenticated session. If user is not logged in, then a different view is loaded instead of the control panel, e.g with a login form. All protected/public page related controllers will extend the website controller. The user homepage has a number of widgets I want to display, which I'm doing via a Home Controller which extends the Website Controller. This controller generates these widgets via the following static calls: $this->template->content->featured_pet = Pet::featured(); $this->template->content->popular_names = Pet::most_popular(); $this->template->content->owner_map = User::generate_map(); $this->template->content->news = News::snippet(); I suppose the first thing I'm unsure about is if the above static calls to controllers (e.g Pet and User) are ok to remain static - these static methods will return views which are loaded into the main template. This is the way I've done things in the past but I'm curious to find out if this is a sensible approach. Other protected pages for signed in users will be similar to the Home Controller. Static pages will be handled by a Page Controller which will also extend the Website Controller, so that it will know whether or not the user control panel or login form should be shown on the left hand side of the template. The protected member only pages will not be routed to the Page Controller, this controller will only handle publicly available pages. One problem I have at the moment, is that if both public and protected pages extend the Website Controller, how do I avoid an infinite loop - for example, the idea is that the website controller should handle authentication then redirect to the requested controller (URL), but this will cause an infinite redirect loop, so i need to come up with a better way of dealing with this. All in all, does this setup make any sense?! Grateful for any feedback.

    Hi there all :) Made this nice little loop for hiding and showing div's, works as a charm in firefox and opera, but IE, safari and chrome say's no.... So my question is; why? function theme(nr){ document.getElementById(nr).style.display = "block"; for (i = 0;i <= 28; i++) { if (i != nr) { document.getElementById(i).style.display = "none"; } } } Thanx:)

  • How to make a batch file edit a text file

    - by William
    I got the code Set objFS = CreateObject("Scripting.FileSystemObject") strFile = "C:\test\file.txt" Set objFile = objFS.OpenTextFile(strFile) Do Until objFile.AtEndOfStream strLine = objFile.ReadLine If InStr(strLine,"ex3")> 0 Then strLine = Replace(strLine,"ex3","ex5") End If WScript.Echo strLine Loop The strLine replacing part i can fix myself to use with my own purposes, but how do i do something like this so that it doesn't require the file's name, it just edits all text files within the document?

  • How do you set Android ViewPager to encompass only one View or Layout?

    - by Kyle
    I am struggling with the concepts needed to properly implement a view pager. By following some tutorials and referencing developer.android.com, I am able to get a view pager almost fully functional. The pager will flip through several text views that have been setup to say "My Message 0" through "My Message 9". The problem is that the view pager also flips the button on the bottom of the activity and the red block that is right above the button. I would like to have the view pager only cycle through the text. Would you please help me understand what I'm doing wrong? I have an activity that represents a dashboard: public class DashBoard extends FragmentActivity { private static final int NUMBER_OF_PAGES = 10; private ViewPager mViewPager; private MyFragmentPagerAdapter mMyFragmentPagerAdapter; public void onCreate(Bundle icicle){ super.onCreate(icicle); setContentView(R.layout.dashboard); mViewPager = (ViewPager) findViewById(R.id.viewpager); mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager()); mViewPager.setAdapter(mMyFragmentPagerAdapter); } private static class MyFragmentPagerAdapter extends FragmentPagerAdapter{ public MyFragmentPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int index) { return PageFragment.newInstance("My Message " + index); } @Override public int getCount(){ return NUMBER_OF_PAGES; } } and a class for the page fragment: public class PageFragment extends Fragment { public static PageFragment newInstance(String title){ PageFragment pageFragment = new PageFragment(); Bundle bundle = new Bundle(); bundle.putString("title", title); pageFragment.setArguments(bundle); return pageFragment; } @Override public void onCreate(Bundle icicle){ super.onCreate(icicle); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle icicle){ View view = inflater.inflate(R.layout.dashboard, container, false); TextView textView = (TextView) view.findViewById(R.id.textViewPage); textView.setText(getArguments().getString("title")); return view; } } and finally, my xml for the dashboard: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/dashbaordLabel" android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" /> <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> <Button android:id="@+id/newGoalButton" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="@string/stringNewGoal" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:onClick="createNewGoal" /> <RelativeLayout android:id="@+id/SpaceBottom" android:layout_width="match_parent" android:layout_height="75dp" android:layout_above="@id/newGoalButton" android:background="@color/red" > </RelativeLayout> </RelativeLayout> A note about my xml, I tried wrapping the text view in some view pager tags eg: <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" > <TextView android:id="@+id/textViewPage" android:layout_width = "match_parent" android:layout_height= "wrap_content" /> </android.support.v4.view.ViewPager> But all that did was make the text view disappear from the screen, while the button and red block still cycled as in the original issue.

  • ADExplorer, how to search with "distinguishedName contains" condition?

    - by Jimm Chen
    I'm using ADExplorer 1.42 from Microsoft. I'm not very versed at this program so please kindly help me out with a search-related problem. Right click on a node(e.g., CN=NlscanStaff) and select Search Container... , with default search attributes, I can see all objects inside NlscanStaff listed as result. Note that there is a CN=CHJTEST object listed. Now, my question is, how to search for CHJTEST specifically? I tried search condition: Attribute : distinguishedName Relation : contains Value : CN=CHJTEST Click Add , then Search . But no result. Can someone tell me what's going wrong? Thanks.

  • How to change from own Internal/Extrernal DNS to use an outsourced service like DNS Made Easy?

    - by Joakim
    Our current setup is a co-located linux box with an openvz kernel with a handful virtual containers for www, mail etc. and one container run Bind9 with a split views configuration serving External and Internal DNS. The HW-Node runs a shorewall firewall and all containers uses private ip's. The box (and DNS) basically handles web and mail for a handful domains and it works well but we still think it would be a good idea to outsource the public DNS and now to my question... Although I am fairly comfortable with the server stuff and DNS, I'm far from a pro and guess I basically need some confirmation that I am thinking in the right direction in that I basically just move the content of our external view (with zone files) to the external service and keep the internal view (or actually remove the view), update the new external DNS with thier names servers, update the info at my registrar and wait for propagation or have I missed something? Maybe someone else here run something similar already and can share some exteriences? I found this question which at least confirms it can be done.

  • How can I use fossil (DVCS) in a home environment?

    - by Mosh
    I'm trying fossil as my new VCS, since I'm a lone developer working on small projects. I started testing fossil but I encountered a (probably major newbie) problem. How does one push or pull to another directory (which is easy on Hg). Fossil pull or push commands expect a URL and not a directory. When I start a server in one directory and try to push from another directory I get the "server loop" error message. Any ideas?

  • Receiving Error Domain=kCFErrorDomainCFNetwork Code=2 when attempting to read from ReadStream

    - by theactiveactor
    I'm attempting to synchronously read from a CFReadStream objected created by CFStreamCreatePairWithSocketToHost. The stream opened fine but when I attempt to invoke CFReadStreamRead on it in a loop, CFReadStreamRead() returns -1 and the resulting error is: Error Domain=kCFErrorDomainCFNetwork Code=2 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 2.)" UserInfo=0x14a920 {kCFGetAddrInfoFailureKey=8} I'm also receiving this same exact error when using this ReadStream asynchronously- the first callback I receive is this error.

  • Filter items from a feed using words in a text file, with Yahoo Pipes

    - by pufferfish
    I have a pipe that filters an RSS feed and removes any item that contains "stopwords" that I've chosen. Currently I've manually created a filter for each stopword in the pipe editor, but the more logical way is to read these from a file. I've figured out how to read the stopwords out of the text file, but how do I apply the filter operator to the feed, once for every stopword? The documentation states explicitly that operators can't be applied within the loop construct, but hopefully I'm missing something here.

  • How to parametrize a test using cppunit

    We are using cppunit, i am trying to run the same test using different parameters, running a loop inside the test is not a good option as any failure will abort the test. I have looked at TestDecorator and TestCaller but neither seem to really fit. Code samples would be helpful. Thanks.

  • Placing component on Glass Pane

    - by Chris Lieb
    I have a subclass of JLabel that forms a component of my GUI. I have implemented the ability to drag and drop the component from one container to another, but without any visual effects. I want to have this JLabel follow the cursor during the drag of the item from one container to another. I figured that I could just create a glass pane and draw it on there. However, even after I add the component to the glass pane, set the component visible, and set the glass pane visible, and set the glass pane as opaque, I still so not see the component. I know the component works because I can add it to the content pane and have it show up.

  • Performance surprise with "as" and nullable types

    - by Jon Skeet
    I'm just revising chapter 4 of C# in Depth which deals with nullable types, and I'm adding a section about using the "as" operator, which allows you to write: object o = ...; int? x = o as int?; if (x.HasValue) { ... // Use x.Value in here } I thought this was really neat, and that it could improve performance over the C# 1 equivalent, using "is" followed by a cast - after all, this way we only need to ask for dynamic type checking once, and then a simple value check. This appears not to be the case, however. I've included a sample test app below, which basically sums all the integers within an object array - but the array contains a lot of null references and string references as well as boxed integers. The benchmark measures the code you'd have to use in C# 1, the code using the "as" operator, and just for kicks a LINQ solution. To my astonishment, the C# 1 code is 20 times faster in this case - and even the LINQ code (which I'd have expected to be slower, given the iterators involved) beats the "as" code. Is the .NET implementation of isinst for nullable types just really slow? Is it the additional unbox.any that causes the problem? Is there another explanation for this? At the moment it feels like I'm going to have to include a warning against using this in performance sensitive situations... Results: Cast: 10000000 : 121 As: 10000000 : 2211 LINQ: 10000000 : 2143 Code: using System; using System.Diagnostics; using System.Linq; class Test { const int Size = 30000000; static void Main() { object[] values = new object[Size]; for (int i = 0; i < Size - 2; i += 3) { values[i] = null; values[i+1] = ""; values[i+2] = 1; } FindSumWithCast(values); FindSumWithAs(values); FindSumWithLinq(values); } static void FindSumWithCast(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { if (o is int) { int x = (int) o; sum += x; } } sw.Stop(); Console.WriteLine("Cast: {0} : {1}", sum, (long) sw.ElapsedMilliseconds); } static void FindSumWithAs(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = 0; foreach (object o in values) { int? x = o as int?; if (x.HasValue) { sum += x.Value; } } sw.Stop(); Console.WriteLine("As: {0} : {1}", sum, (long) sw.ElapsedMilliseconds); } static void FindSumWithLinq(object[] values) { Stopwatch sw = Stopwatch.StartNew(); int sum = values.OfType<int>().Sum(); sw.Stop(); Console.WriteLine("LINQ: {0} : {1}", sum, (long) sw.ElapsedMilliseconds); } }

  • how can i convert a .tpl file to a .php file? [closed]

  • Mercurial outgoing Hook

    I'm looking to create a Mercurial hook that pushes to a backup remote repository when I push to a local repository. I thought I could hook the 'outgoing' hook, but this creates a infinite loop that isn't pretty. So is there like a post-push hook, or would it be best to have the repository I am pushing to have an 'incoming' hook to push the to the remote backup instead?

  • Basic video editor for AVCHD Lite files?

    - by davr
    I have a camera (Panasonic Lumix GF-1) that outputs "AVCHD Lite" files, 720p h264 in a MTS container. I saw this question that said Movie Maker in Windows 7 supports AVCHD...but I just tried, and unfortunately it does not support AVCHD Lite. Are there any free or inexpensive non-linear video editors (NLE) that can natively handle AVCHD Lite files, without requiring some 3rd party driver? If not, are there any 3rd party drivers that are especially stable? (In my experience they usually have some problems...I got AVCHD Lite loading into VirtualDub using a 3rd party plugin, but it's very slow and sometimes crashes, and seeking takes ages.
