  • PowerShell locking File....

    - by Ben
    I am trying to do something very simple in powershell Reading the contents of a file Manipulation some string Saving the modified test back to the file function Replace { $file = Get-Content C:\Path\File.cs $file | foreach {$_ -replace "document.getElementById", "$"} |out-file -filepath C:\Path\File.cs } I have tried Set-Content as well. I always get unautorized exception. I can see the $file has the file content, error is coming while writing the file. Any help is appreciated. Ben

  • How to keep multiple connectionString passwords safe, separate, and easy to deploy?

    - by Funka
    I know there are plenty of questions here already about this topic (I've read through as many as I could find), but I haven't yet been able to figure out how best to satisfy my particular criteria. Here are the goals: The ASP.NET application will run on a few different web servers, including localhost workstations for development. This means encrypting web.config using a machine key is out. The application will decide which connection string to use based on the server name (using a switch statement). For example, "localhost" and "dev.example.com" will use the DevDatabaseConnectionString, "test.example.com" will use the TestDatabaseConnectionString, and "www.example.com" will use the ProdDatabaseConnectionString, for example. Ideally, the exact same executables and web.config should be able to run on any of these environments, without needing to tailor or configure each environment separately every time that we deploy (something that seems like it would be easy to forget/mess up one day during a deployment, which is why we moved away from having just one connectionstring that has to be changed on each target). Deployment is currently accomplished via FTP. We will not have command-line access to the production web server. This means using aspnet_regiis.exe is out. (I could run on localhost, however, if this would still work.) We would prefer to not have to recompile the application whenever a password changes, so using web.config (or db.config or whatever) seems to make the most sense. A developer should not be able to decrypt the production database password. If a developer checks the source code out onto their localhost laptop (which would determine that it should be using the DevDatabaseConnectionString, remember?) and the laptop gets lost or stolen, it should not be possible to get at the other connection strings. Thus, having a single RSA private key to un-encrypt all three passwords cannot be considered. (Contrary to #3 above, it does seem like we'd need to have three separate key files if we went this route; these could be installed once per machine, and should the wrong key file get deployed to the wrong server, the worst that should happen is that the app can't decrypt anything---and not allow the wrong host to access the wrong database!) I know this is probably a subjective question (asking for a "best" way to do something), but given the criteria I've mentioned, I'm hoping that a single best answer will indeed arise. Thank you!

  • How to access Active Directory using C++Builder?

    - by Gus Brown
    I need to get a list of user names from Active Directory using C++Builder. I know I could shell out to batch file and run the csvde.exe command but surely there is a nicer way using a library or something, right? Are there any C++ libraries? (hopefully with examples?) Many thanks! -Dan

  • How to integer-divide round negative numbers *down*?

    - by Conrad Albrecht
    Seems like whenever I divide a negative int by a positive int, I need it to round down (toward -inf), not toward 0. But both C# and C++ round toward 0. So I guess I need a DivideDownward() method. I can write it in a few lines with a test for negative and so on, but my ideas seem klugey. So I'm wondering if I'm missing something and if you have an "elegant" way to round negative division downward.

  • Unique_ptr compiler errors

    - by Godric Seer
    I am designing and entity-component system for a project, and C++ memory management is giving me a few issues. I just want to make sure my design is legitimate. So to start I have an Entity class which stores a vector of Components: class Entity { private: std::vector<std::unique_ptr<Component> > components; public: Entity() { }; void AddComponent(Component* component) { this -> components.push_back(std::unique_ptr<Component>(component)); } ~Entity(); }; Which if I am not mistaken means that when the destructor is called (even the default, compiler created one), the destructor for the Entity, will call ~components, which will call ~std::unique_ptr for each element in the vector, and lead to the destruction of each Component, which is what I want. The component class has virtual methods, but the important part is its constructor: Component::Component(Entity parent) { parent.addComponent(this) // I am not sure if this would work like I expect // Other things here } As long as passing this to the method works, this also does what I want. My confusion is in the factory. What I want to do is something along the lines of: std::shared_ptr<Entity> createEntity() { std::shared_ptr<Entity> entityPtr(new Entity()); new Component(*parent); // Initialize more, and other types of Components return entityPtr; } Now, I believe that this setup will leave the ownership of the Component in the hands of its Parent Entity, which is what I want. First a small question, do I need to pass the entity into the Component constructor by reference or pointer or something? If I understand C++, it would pass by value, which means it gets copied, and the copied entity would die at the end of the constructor. The second, and main question is that code based on this sample will not compile. The complete error is too large to print here, however I think I know somewhat of what is going on. The compiler's error says I can't delete an incomplete type. My Component class has a purely virtual destructor with an implementation: inline Component::~Component() { }; at the end of the header. However since the whole point is that Component is actually an interface. I know from here that a complete type is required for unique_ptr destruction. The question is, how do I work around this? For reference I am using gcc 4.4.6.

    - by pyrony
    I am having a hard time figuring out a reasonable way to generate a mixed-case hash in Python. I want to generate something like: aZeEe9E Right now I'm using MD5, which doesn't generate case-sensitive hashes. What is a good way to generate a hash value consisting of upper- and lower- case characters + numbers?

  • Android listview array adapter selected

    - by João Melo
    i'm trying to add a contextual action mode to a listview, but i'm having some problems with the selection, if i make aList1.setSelection(position) it doesn't select anything, and if i make List1.setItemChecked(position, true) it works but it only changes the font color a little and i want it to change the background or something more notable, is there any way to detect the selection and manually and change the background, or i'm missing something? the list: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" > <ListView android:id="@+id/list1" android:layout_width="match_parent" android:layout_height="match_parent" android:choiceMode="singleChoice" android:drawSelectorOnTop="false"> </ListView> </RelativeLayout> the adapter: public class ServicesRowAdapter extends ArrayAdapter<String[]> { private final Activity context; private final ArrayList<String[]> names; static class ViewHolder { public TextView Id; public TextView Date; public RelativeLayout statusbar,bglayout; } public ServicesRowAdapter(Activity context, ArrayList<String[]> names) { super(context, R.layout.servicesrowlayout, names); this.context = context; this.names = names; } @Override public View getView(int position, View convertView, ViewGroup parent) { View rowView = convertView; if (rowView == null) { LayoutInflater inflater = context.getLayoutInflater(); rowView = inflater.inflate(R.layout.servicesrowlayout, null); ViewHolder viewHolder = new ViewHolder(); viewHolder.Id = (TextView) rowView.findViewById(R.id.idlabel); viewHolder.Date = (TextView) rowView.findViewById(R.id.datelabel); rowView.setTag(viewHolder); } ViewHolder holder = (ViewHolder) rowView.getTag(); holder.Date.setText(names.get(position)[2]); holder.Id.setText(names.get(position)[1]); return rowView; } } with the use of a layout: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" > <TextView android:id="@+id/idlabel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:gravity="right" android:text="@+id/idlabel" android:textSize="20dp" android:width="70dp" > </TextView> <TextView android:id="@+id/datelabel" android:layout_centerVertical="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@+id/datelabel" android:textSize="20dp" android:layout_marginLeft="90dp" > </TextView> </RelativeLayout

  • LINQ query on a DataTable

    - by Calanus
    I'm trying to perform a LINQ query on a DataTable object and bizarrely I am finding that performing such queries on DataTables is not straightforward. For example: var results = from myRow in myDataTable where results.Field("RowNo") == 1 select results; This is not allowed. Any ideas how to get something like this working? I'm amazed that LINQ queries are not allowed on DataTables!

  • EADDRNOTAVAIL when binding 127.0.0.1 on localhost?

    - by Jonas Byström
    I'm getting errno==49 (EADDRNOTAVAIL) when trying to UDP-bind() to 127.0.0.1:47346 running Mac OS X on a G5 (big endian PowerPC). Is there something preventing me from doing so? I've tried other addresses and ports (192.168.1.2 and port 47346) but with no success. Here's a gdb printout of my sockaddr_in: $1 = { sin_len = 0 '\0', sin_family = 2 '\002', sin_port = 47346, sin_addr = { s_addr = 3232235778 }, sin_zero = "???\000\000??" }

  • Installer Creators? What do you recommend?

    - by bobber205
    Can't find a generic topic about this but what do you guys recommend for an application that creates a simple installer? Just need something that places it into an appropriate folder in Program Files, adds shortcuts to the StartMenu. My professor recommend Superpimp but that seems like overkill. :P Thanks SO!

  • What happened to programming-books.com?

    - by Kurtosis
    A couple years ago I found a great site called something like 'programming-books.com' (but not exactly that). It let users submit links to their favorite books for various programming languages, and write a short blurb about why they're so good. You could include their Amazon page and the website would grab a cover picture. I've since lost that bookmark and am trying to find it again, anyone know what site I'm talking about? Is it still around? (cross-posted @ hacker news)

  • How to read a file byte by byte in Python?

    - by zaplec
    Hi, I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that: file = open(filename, 'rb') while 1: byte = file.read(8) # Do something... So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks.

  • Conditional action based on whether any file in a directory has a ctime newer than X

    - by jberryman
    I would like to run a backup job on a directory tree from a bash script if any of the files have been modified in the last 30 minutes. I think I can hack together something using find with the -ctime flag, but I'm sure there is a standard way to examine a directory for changes. I know that I can inspect the ctime of the top level directory to see if files were added, but I need to be able to see changes also. FWIW, I am using duplicity to backup directories to S3.

  • Fleunt NHibernate not working outside of nunit test fixtures

    - by thorkia
    Okay, here is my problem... I created a Data Layer using the RTM Fluent Nhibernate. My create session code looks like this: _session = Fluently.Configure(). Database(SQLiteConfiguration.Standard.UsingFile("Data.s3db")) .Mappings( m => { m.FluentMappings.AddFromAssemblyOf<ProductMap>(); m.FluentMappings.AddFromAssemblyOf<ProductLogMap>(); }) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); When I reference the module in a test project, then create a test fixture that looks something like this: [Test] public void CanAddProduct() { var product = new Product {Code = "9", Name = "Test 9"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); using (ISession session = OrmHelper.OpenSession()) { var fromDb = session.Get<Product>(product.Id); Assert.IsNotNull(fromDb); Assert.AreNotSame(fromDb, product); Assert.AreEqual(fromDb.Id, product.Id); } My tests pass. When I open up the created SQLite DB, the new Product with Code 9 is in it. the tables for Product and ProductLog are there. Now, when I create a new console application, and reference the same library, do something like this: Product product = new Product() {Code = "10", Name = "Hello"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); Console.WriteLine(product.Id); Console.ReadLine(); It doesn't work. I actually get pretty nasty exception chain. To save you lots of head aches, here is the summary: Top Level exception: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.\r\n\r\n The PotentialReasons collection is empty The Inner exception: The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly. Both the unit test library and the console application reference the exact same version of System.Data.SQLite. Both projects have the exact same DLLs in the debug folder. I even tried copying SQLite DB the unit test library created into the debug directory of the console app, and removed the build schema lines and it still fails If anyone can help me figure out why this won't work outside of my unit tests it would be greatly appreciated. This crazy bug has me at a stand still.
