  • USB windows xp final USB access issues

    - by Lex Dean
    I basically understand you C++ people, Please do not get distracted because I'm writing in Delphi. I have a stable USB Listing method that accesses all my USB devices I get the devicepath, and this structure: TSPDevInfoData = packed record Size: DWORD; ClassGuid: TGUID; DevInst: DWORD; // DEVINST handle Reserved: DWord; end; I get my ProductID and VenderID successfully from my DevicePath Lists all USB devices connected to the computer at the time That enables me to access the registry data to each device in a stable way. What I'm lacking is a little direction Is friendly name able to be written inside the connected USB Micro chips by the firmware programmer? (I'm thinking of this to identify the device even further, or is this to help identify Bulk data transfer devices like memory sticks and camera's) Can I use SPDRP_REMOVAL_POLICY_OVERRIDE to some how reset these polices What else can I do with the registry details. Identifying when some one unplugs a device The program is using (in windows XP standard) I used a documented windows event that did not respond. Can I read a registry value to identify if its still connected? using CreateFileA (DevicePath) to send and receive data I have read when some one unplugs in the middle of a data transfer its difficult clearing resources. what can IoCreateDevice do for me and how does one use it for that task This two way point of connection status and system lock up situations is very concerning. Has some one read anything about this subject recently? My objectives are to 1. list connected USB devices identify a in development Micro Controller from everything else send and receive data in a stable and fast way to the limits of the controller No lock up's transferring data Note I'm not using any service packs I understand everything USB is in ANSI when windows xp is not and .Net is all about ANSI (what a waste of memory) I plan to continue this project into a .net at a later date as an addition. MSDN gives me Structures and Functions and what should link to what ok but say little to what they get used for. What is available in my language Delphi is way over priced that it needs a major price drop.

  • Internal class and access to external members.

    - by Knowing me knowing you
    I always thought that internal class has access to all data in its external class but having code: template<class T> class Vector { template<class T> friend std::ostream& operator<<(std::ostream& out, const Vector<T>& obj); private: T** myData_; std::size_t myIndex_; std::size_t mySize_; public: Vector():myData_(nullptr), myIndex_(0), mySize_(0) { } Vector(const Vector<T>& pattern); void insert(const T&); Vector<T> makeUnion(const Vector<T>&)const; Vector<T> makeIntersection(const Vector<T>&)const; class Iterator : public std::iterator<std::bidirectional_iterator_tag,T> { private: T** itData_; public: Iterator()//<<<<<<<<<<<<<------------COMMENT { /*HERE I'M TRYING TO USE ANY MEMBER FROM Vector<T> AND I'M GETTING ERR SAYING: ILLEGAL CALL OF NON-STATIC MEMBER FUNCTION*/} Iterator(T** ty) { itData_ = ty; } Iterator operator++() { return ++itData_; } T operator*() { return *itData_[0]; } bool operator==(const Iterator& obj) { return *itData_ == *obj.itData_; } bool operator!=(const Iterator& obj) { return *itData_ != *obj.itData_; } bool operator<(const Iterator& obj) { return *itData_ < *obj.itData_; } }; typedef Iterator iterator; iterator begin()const { assert(mySize_ > 0); return myData_; } iterator end()const { return myData_ + myIndex_; } }; See line marked as COMMENT. So can I or I can't use members from external class while in internal class? Don't bother about naming, it's not a Vector it's a Set. Thank you.

  • C# Property Access vs Interface Implementation

    - by ehdv
    I'm writing a class to represent a Pivot Collection, the root object recognized by Pivot. A Collection has several attributes, a list of facet categories (each represented by a FacetCategory object) and a list of items (each represented by a PivotItem object). Therefore, an extremely simplified Collection reads: public class Collection { private List<FacetCategory> categories; private List<PivotItem> items; // other attributes } What I'm unsure of is how to properly grant access to those two lists. Because declaration order of both facet categories and items is visible to the user, I can't use sets, but the class also shouldn't allow duplicate categories or items. Furthermore, I'd like to make the Collection object as easy to use as possible. So my choices are: Have Collection implement IList<PivotItem> and have accessor methods for FacetCategory: In this case, one would add an item to Collection foo by writing foo.Add(bar). This works, but since a Collection is equally both kinds of list making it only pass as a list for one type (category or item) seems like a subpar solution. Create nested wrapper classes for List (CategoryList and ItemList). This has the advantage of making a consistent interface but the downside is that these properties would no longer be able to serve as lists (because I need to override the non-virtual Add method I have to implement IList rather than subclass List. Implicit casting wouldn't work because that would return the Add method to its normal behavior. Also, for reasons I can't figure out, IList is missing an AddRange method... public class Collection { private class CategoryList: IList<FacetCategory> { // ... } private readonly CategoryList categories = new CategoryList(); private readonly ItemList items = new ItemList(); public CategoryList FacetCategories { get { return categories; } set { categories.Clear(); categories.AddRange(value); } } public ItemList Items { get { return items; } set { items.Clear(); items.AddRange(value); } } } Finally, the third option is to combine options one and two, so that Collection implements IList<PivotItem> and has a property FacetCategories. Question: Which of these three is most appropriate, and why?

  • Can't access font resource in Silverlight class library

    - by Matt
    I have a reasonably large Silveright 3.0 project on the go, and I'm having issues accessing a couple of custom font resources from within one of the assemblies. I've got a working test solution where I have added a custom font as a resource, and can access it fine from XAML using: <TextBlock Text="Test" FontFamily="FontName.ttf#Font Name" /> The test solution consists of the TestProject.Application and the TestProject.Application.Web projects, with all the fun and games obviously in the TestProject.Application project However, when I try this in my main solution, the fonts refuse to show in the correct type face (instead showing in the default font). There's no difference in the way the font has been added to project between the test solution and the main solution, and the XAML is identical. However, there is a solution layout difference. In the main solution, as well as having a MainApp.Application and MainApp.Application.Web project, I also have a MainApp.Application.ViewModel project and a MainApp.Application.Views project, and the problem piece of XAML is the in the MainApp.Application.Views project (not the .Application project like the test solution). I've tried putting the font into either the .Application or .Application.Views project, tried changing the Build Action to Content, Embedded Resource etc, all to no avail. So, is there an issue accessing font resources from a child assembly that I don't know about, or has anyone successfully done this? My long term need will be to have the valid custom fonts being stored as resources in a separate .Application.FontLibrary assembly that will be on-demand downloaded and cached, and the XAML controls in the .Application.Views project will need to reference this FontLibrary assembly to get the valid fonts. I've also tried xcreating this separate font library assembly, and I can't seem to get the fonts from the second assembly. As some additional information, I've also tried the following font referencing approaches: <TextBlock Text="Test" FontFamily="/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;component/FontName.ttf#Font Name" /> And a few similar variants with different assembly references/sub directories/random semi colons. And so far nothing works... anyone struck this (and preferably solved it)?

  • C# Serialization Surrogate - Cannot access a disposed object

    - by crushhawk
    I have an image class (VisionImage) that is a black box to me. I'm attempting to serialize the image object to file using Serialization Surrogates as explained on this page. Below is my surrogate code. sealed class VisionImageSerializationSurrogate : ISerializationSurrogate { public void GetObjectData(Object obj, SerializationInfo info, StreamingContext context) { VisionImage image = (VisionImage)obj; byte[,] temp = image.ImageToArray().U8; info.AddValue("width", image.Width); info.AddValue("height", image.Height); info.AddValue("pixelvalues", temp, temp.GetType()); } public Object SetObjectData(Object obj, SerializationInfo info, StreamingContext context, ISurrogateSelector selector) { VisionImage image = (VisionImage)obj; Int32 width = info.GetInt32("width"); Int32 height = info.GetInt32("height"); byte[,] temp = new byte[height, width]; temp = (byte[,])info.GetValue("pixelvalues", temp.GetType()); PixelValue2D tempPixels = new PixelValue2D(temp); image.ArrayToImage(tempPixels); return image; } } I've stepped through it to write to binary. It seems to be working fine (file is getting bigger as the images are captured). I tried to test it read the file back in. The values read back in are correct as far as the "info" object is concerned. When I get to the line image.ArrayToImage(tempPixels); It throws the "Cannot access a disposed object" exception. Upon further inspection, the object and the resulting image are both marked as disposed. My code behind the form spawns an "acquisitionWorker" and runs the following code. void acquisitionWorker_LoadImages(object sender, DoWorkEventArgs e) { // This is the main function of the acquisition background worker thread. // Perform image processing here instead of the UI thread to avoid a // sluggish or unresponsive UI. BackgroundWorker worker = (BackgroundWorker)sender; try { uint bufferNumber = 0; // Loop until we tell the thread to cancel or we get an error. When this // function completes the acquisitionWorker_RunWorkerCompleted method will // be called. while (!worker.CancellationPending) { VisionImage savedImage = (VisionImage) formatter.Deserialize(fs); CommonAlgorithms.Copy(savedImage, imageViewer.Image); // Update the UI by calling ReportProgress on the background worker. // This will call the acquisition_ProgressChanged method in the UI // thread, where it is safe to update UI elements. Do not update UI // elements directly in this thread as doing so could result in a // deadlock. worker.ReportProgress(0, bufferNumber); bufferNumber++; } } catch (ImaqException ex) { // If an error occurs and the background worker thread is not being // cancelled, then pass the exception along in the result so that // it can be handled in the acquisition_RunWorkerCompleted method. if (!worker.CancellationPending) e.Result = ex; } } What am I missing here? Why would the object be immediately disposed?

  • MSSQL using SSH-tunnel from Visual Studio

    - by pbt
    Hi, I recently contacted a web host regarding support for external database access to a Microsoft SQL Database included in a package they offer. They replied saying that it is only possible with an SSH-tunnel. Is it possible to connect to a MS SQL database in Visual Studio using an SSH-tunnel? It is important for me to be able to access the database from my local machine (for debugging, generating LINQ classes, editing tables, etc). Or, how should I go about working with their database?

  • Dynamic swappable Data Access Layer

    - by Andy
    I'm writing a data driven WPF client. The client will typically pull data from a WCF service, which queries a SQL db, but I'd like the option to pull the data directly from SQL or other arbitrary data sources. I've come up with this design and would like to hear your opinion on whether it is the best design. First, we have some data object we'd like to extract from SQL. // The Data Object with a single property public class Customer { private string m_Name = string.Empty; public string Name { get { return m_Name; } set { m_Name = value;} } } Then I plan on using an interface which all data access layers should implement. Suppose one could also use an abstract class. Thoughts? // The interface with a single method interface ICustomerFacade { List<Customer> GetAll(); } One can create a SQL implementation. // Sql Implementation public class SqlCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Query SQL db and return something useful // ... return new List<Customer>(); } } We can also create a WCF implementation. The problem with WCF is is that it doesn't use the same data object. It creates its own local version, so we would have to copy the details over somehow. I suppose one could use reflection to copy the values of similar fields across. Thoughts? // Wcf Implementation public class WcfCustomrFacade : ICustomerFacade { public List<Customer> GetAll() { // Get date from the Wcf Service (not defined here) List<WcfService.Customer> wcfCustomers = wcfService.GetAllCustomers(); // The list we're going to return List<Customer> customers = new List<Customer>(); // This is horrible foreach(WcfService.Customer wcfCustomer in wcfCustomers) { Customer customer = new Customer(); customer.Name = wcfCustomer.Name; customers.Add(customer); } return customers; } } I also plan on using a factory to decide which facade to use. // Factory pattern public class FacadeFactory() { public static ICustomerFacade CreateCustomerFacade() { // Determine the facade to use if (ConfigurationManager.AppSettings["DAL"] == "Sql") return new SqlCustomrFacade(); else return new WcfCustomrFacade(); } } This is how the DAL would typically be used. // Test application public class MyApp { public static void Main() { ICustomerFacade cf = FacadeFactory.CreateCustomerFacade(); cf.GetAll(); } } I appreciate your thoughts and time.

  • c++ setting string attribute value in class is throwing "Access violation reading location"

  • Can't access Elements previously created by innerHTML with Javascript/Prototype

    - by Joe Hopfgartner
    I am setting the innerHTML variable of a div with contents from an ajax request: new Ajax.Request('/search/ajax/allakas/?ext_id='+extid, { method:'get', onSuccess: function(transport){ var response = transport.responseText || "no response text"; $('admincovers_content').innerHTML=response; }, onFailure: function(){ alert('Something went wrong...') } }); The response text cotains a form: <form id="akas-admin" method="post" action="/search/ajax/modifyakas/"> <input type="text" name="formfield" value="i am a form field"/> </form> Then I call a functiont that should submit that form: $('akas-admin').request({ onComplete: function(transport){ //alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); The problem is $('akas-admin) returns null , I tried to put the form with this id in the original document, which works. Question: Can I somehow "revalidate" the dom or access elements that have been inserted with innerHTML? Edit Info: document.getElementById("akas-admin").submit() works just fine, problem is i don't want to reload the whole page but post the form over ajax and get the response text in a callback function. Edit: Based on the answers provided, i replaced my function that does the request with the following observer: Event.observe(document.body, 'click', function(event) { var e = Event.element(event); if ('aka-savelink' == e.identify()) { alert('savelink clicked!'); if (el = e.findElement('#akas-admin')) { alert('found form to submit it has id: '+el.identify()); el.request({ onComplete: function(transport){ alert('Form data saved! '+transport.responseText) $('admincovers_content').innerHTML=transport.responseText; } }); } } }); problem is that i get as far as alert('savelink clicked!'); . findelement doesnt return the form. i tried to place the save link above and under the form. both doesnt work. i also think this approach is a bit clumsy and i am doing it wrong. could anyone point me in the right direction?

  • Non-functioning AutoFilter on Locked Cells in Office 2008 - works in Office 2007

    - by Sarcas
    I'm looking into a problem for someone, who works in a mixed OS environment. She has created an Excel spreadsheet in Office 2007 to act as a directory, with AutoFilter turned on for names, email addresses, departments etc. To make sure no one accidentally edits email addresses (for example), she has protected the work sheet. Accessing this worksheet on a PC running Excel 2007, everything runs as you'd expect. You can filter the sheet by any of the auto-filtered columns, and because the sheet is protected, the data integrity is guaranteed. However, if you access the sheet on a Mac running Excel 2008, you can't filter the columns. What's strange here is that the AutoFilter dropdown arrows do appear in each of the column headers as you would expect. It's just that nothing happens if you click on them. If you select one of the column header cells (say, 'First Name') and check the menu: Data-Filter, you can see that AutoFilter is ticked. As another datapoint, you also seem to be able to apply an Advanced filter to these rows on the protected sheets. Does anyone know why this might be? It seems to be a compatibility issue between Excel 2007/2008 (I know the codebase isn't the same), but I can't find any references to it in documentation or forums anywhere, and it would be good to know if there's a way around this. Thanks!

  • MS SQL to MySQL using MySQL Migration Toolkit: permission issue

    - by Zeno
    I have a MS SQL imported into SQL Server 2008 from a .bak and I set it to Mixed mode. I have a SQL user (called "test") that can correctly access the database using SQL Server. I need to convert this to a MySQL database, so I got the MySQL Migration Toolkit. I pick "MS SQL Server" and then it asks for the hostname/username/password/database. I'm not 100% sure on these, but I used "localhost" (running on same computer), left the port as is (1433) and the username/password ("test") for the SQL Server. And I used the database name for the SQL Server database I'm looking to import. I clicked next, enter my MySQL database details and then attempt to run it and I get this error: Connecting to source database and retrieve schemata names. Initializing JDBC driver ...

  • Migrate users from one Active Directory domain to another?

    - by Matt
    I work for a company that hosts desktops for a number of different companies. At the moment, all the clients access a single domain controller called HOSTING. Under that are groups for each company. Each of the hosting servers exist on the same network and so are therefore potentially browseable by other terminal servers. This has raised some security issues and I've found it a little tricky to manage the security. As well, it's possible to see who the other hosted companies are even though other users cannot see their data. What I'd like to do is isolate each clients terminal server/s into their own VLAN. In addition, I'm thinking that each TS would have it's own DC which could just run on the TS for that company. Overhead for a DC is fairly minimal. This would isolate users on that TS from seeing the other companies completely. Firstly, does this sound like a sensible plan? Second... if it is sensible, how would I go about pulling the accounts from the HOSTING domain to a new domain? ideally, without the need for users to change their passwords?

  • Office Compatibility Pack and File Permissions

    - by hymie
    MS isn't my thing, so I hope somebody can give me a pointer. We have a Windows domain, with a Server-2003-SP1-Enterprise file server. One of the specific files is a MS Excel 2007 (XLSX) file created by user LK. In the "Security" preferences setting, about a half-dozen users (including me) have access to this file. LK is the owner and has "full control", while the rest of us have "Read" , "Read & Execute", and "Write" permission. LK is also the owner of the directory that this file resides in. I don't know if that's relevant. So far so good. My desktop machine has Windows XP SP3 , and Excel 2003 SP3 , and the "Office Compatibility Pack" which lets me read and write the new XLSX files. However, whenever I write the file, the permissions are changed. The newly-written file only has permissions for LK and me, and both are "Full control" So in short, what am I doing wrong, and how should I set this up to do it right, keeping the permissions on the file that were there when I started?

  • Windows Server 2012 licensing issue preventing RDP connections?

    - by QF_Developer
    I am witnessing an unusual behaviour on 1 of 5 Windows Server 2012 R2 machines (clean install) that is preventing any remote connections from being established via RDP. I have run through the prerequisites for RDP here but I am finding that any remote connection attempt instantly stops the "Windows Protection Service". When I check the event logs I see the following entry. The Software Protection Service has stopped Event ID: 903 Source: Security-SPP From what I have read Security-SPP is tasked with enforcing activation and licensing, it appears that RDP requires this service to be in the running state. Is it possible that I have inadvertently activated this instance of Windows with a key that has already been associated to another instance (We have 5 keys as part of an MSDN subscription)? Would this be sufficient to block RDP access? When I look under System Properties (Windows Activation) it states that Windows is activated and there are no other obvious indicators that there's a licensing issue. EDIT 1: I ran a Powershell script to display the product keys for all servers in order to check for any duplication. For the problematic server I am getting the message The RPC server is unavailable.

  • Architecture for a business objects / database access layer

    - by gregmac
    For various reasons, we are writing a new business objects/data storage library. One of the requirements of this layer is to separate the logic of the business rules, and the actual data storage layer. It is possible to have multiple data storage layers that implement access to the same object - for example, a main "database" data storage source that implements most objects, and another "ldap" source that implements a User object. In this scenario, User can optionally come from an LDAP source, perhaps with slightly different functionality (eg, not possible to save/update the User object), but otherwise it is used by the application the same way. Another data storage type might be a web service, or an external database. There are two main ways we are looking at implementing this, and me and a co-worker disagree on a fundamental level which is correct. I'd like some advice on which one is the best to use. I'll try to keep my descriptions of each as neutral as possible, as I'm looking for some objective view points here. Business objects are base classes, and data storage objects inherit business objects. Client code deals with data storage objects. In this case, common business rules are inherited by each data storage object, and it is the data storage objects that are directly used by the client code. This has the implication that client code determines which data storage method to use for a given object, because it has to explicitly declare an instance to that type of object. Client code needs to explicitly know connection information for each data storage type it is using. If a data storage layer implements different functionality for a given object, client code explicitly knows about it at compile time because the object looks different. If the data storage method is changed, client code has to be updated. Business objects encapsulate data storage objects. In this case, business objects are directly used by client application. Client application passes along base connection information to business layer. Decision about which data storage method a given object uses is made by business object code. Connection information would be a chunk of data taken from a config file (client app does not really know/care about details of it), which may be a single connection string for a database, or several pieces connection strings for various data storage types. Additional data storage connection types could also be read from another spot - eg, a configuration table in a database that specifies URLs to various web services. The benefit here is that if a new data storage method is added to an existing object, a configuration setting can be set at runtime to determine which method to use, and it is completely transparent to the client applications. Client apps do not need to be modified if data storage method for a given object changes. Business objects are base classes, data source objects inherit from business objects. Client code deals primarily with base classes. This is similar to the first method, but client code declares variables of the base business object types, and Load()/Create()/etc static methods on the business objects return the appropriate data source-typed objects. The architecture of this solution is similar to the first method, but the main difference is the decision about which data storage object to use for a given business object is made by the business layer, not the client code. I know there are already existing ORM libraries that provide some of this functionality, but please discount those for now (there is the possibility that a data storage layer is implemented with one of these ORM libraries) - also note I'm deliberately not telling you what language is being used here, other than that it is strongly typed. I'm looking for some general advice here on which method is better to use (or feel free to suggest something else), and why.

  • StaleDataException: access closed cursor

    - by Aurora
    In my application, after enough clicking around, I get this error: 06-08 19:47:59.967: ERROR/AndroidRuntime(2429): java.lang.RuntimeException: Unable to pause activity {com.MYAPP.app/com.MYAPP.app.MainActivity}: android.database.StaleDataException: Access closed cursor What I have is a Tab Activity (my MainActivity), which has a ListActivity as the contents for each tab. Inside the onCreate for each ListActivity I get a cursor that represents the data to be displayed in that list. The onListItemClick for each list also creates another activity, so clicking on an item in the list will show more information about that item in a new screen. It's inconsistent, but after enough clicking into these new activities, or going back to the ListView from a new activity, the program crashes. In searching around for a solution to my problem, I did stumble upon registerDataSetObserver, but it doesn't seem to be the whole answer. I am also having trouble finding documentation on it, so I'm not sure I fully understand it. I have a custom ListAdapter that both my ListViews use and have called registerDataSetObservers on the cursors there. I have attached the relevant code from one of my ListActivities and from my custom ListAdapter class. The ListActivity. I have two of these, almost identical, except they both have different cursors created from different database queries: import com.MYAPP.app.listmanager.DeviceListAdapter; public class AllSensorsActivity extends ListActivity{ private DeviceListAdapter AllList; private DbManager db; protected Cursor AllCur; protected Cursor AllSensors; private static final String TAG = "AllSensorsActivity"; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); Log.e(TAG, "Calling All onCreate"); db = new DbManager(this); db.open(); AllCur = db.fetchAllDevices(); startManagingCursor(AllCur); AllSensors = db.fetchAllSensors(); startManagingCursor(AllSensors); AllList = new DeviceListAdapter(this, AllCur, AllSensors); setListAdapter(AllList); } @Override protected void onListItemClick(ListView l, View v, int position, long id){ String device_name = (String) ((DeviceListAdapter)getListAdapter()).getItem(position); String sensor_string = ((DeviceListAdapter)getListAdapter()).getSensors(id); Intent i = new Intent(this, SensorActivity.class); Bundle bundle = new Bundle(); bundle.putString("NAME", device_name); i.putExtras(bundle); bundle.putString("SENSORS", sensor_string); i.putExtras(bundle); this.startActivity(i); } The custom ListAdapter: public class DeviceListAdapter extends BaseAdapter { private static final String TAG = "DeviceListAdapter"; private Context mContext; private Cursor mSensors; private Cursor mDevices; protected MyDataSetObserver sensors_observer; protected MyDataSetObserver devices_observer; public DeviceListAdapter(Context context, Cursor devices, Cursor sensors){ mContext = context; mDevices = devices; mSensors = sensors; sensors_observer = new MyDataSetObserver(); mSensors.registerDataSetObserver(sensors_observer); devices_observer = new MyDataSetObserver(); mDevices.registerDataSetObserver(devices_observer); } // ... more functions and stuff that are not relevant go down here... } private class MyDataSetObserver extends DataSetObserver { public void onChanged(){ Log.e(TAG, "CHANGED CURSOR!"); } public void onInvalidated(){ Log.e(TAG, "INVALIDATED CURSOR!"); } } Should I just have MyDataSetObserver catch the exception and move on? I'd like a more robust solution than that if possible. Or is there some other way I could rearrange my program so that the staleDataException doesn't occur (as often)? I believe that it is happening because I am launching the new activity in my onListItemClick.

  • Using boost locks for RAII access to a semaphore

    - by dan
    Suppose I write a C++ semaphore class with an interface that models the boost Lockable concept (i.e. lock(); unlock(); try_lock(); etc.). Is it safe/recommended to use boost locks for RAII access to such an object? In other words, do boost locks (and/or other related parts of the boost thread library) assume that the Lockable concept will only be modeled by mutex-like objects which are locked and unlocked from the same thread? My guess is that it should be OK to use a semaphore as a model for Lockable. I've browsed through some of the boost source and it "seems" OK. The locks don't appear to store explicit references to this_thread or anything like that. Moreover, the Lockable concept doesn't have any function like whichThreadOwnsMe(). It also looks like I should even be able to pass a boost::unique_lock<MySemaphore> reference to boost::condition_variable_any::wait. However, the documentation is not explicitly clear about the requirements. To illustrate what I mean, consider a bare-bones binary semaphore class along these lines: class MySemaphore{ bool locked; boost::mutex mx; boost::condition_variable cv; public: void lock(){ boost::unique_lock<boost::mutex> lck(mx); while(locked) cv.wait(lck); locked=true; } void unlock(){ { boost::lock_guard<boost::mutex> lck(mx); if(!locked) error(); locked=false; } cv.notify_one(); } // bool try_lock(); void error(); etc. } Now suppose that somewhere, either on an object or globally, I have MySemaphore sem; I want to lock and unlock it using RAII. Also I want to be able to "pass" ownership of the lock from one thread to another. For example, in one thread I execute void doTask() { boost::unique_lock<MySemaphore> lock(sem); doSomeWorkWithSharedObject(); signalToSecondThread(); waitForSignalAck(); lock.release(); } While another thread is executing something like { waitForSignalFromFirstThread(); ackSignal(); boost::unique_lock<MySemaphore>(sem,boost::adopt_lock_t()); doMoreWorkWithSameSharedObject(); } The reason I am doing this is that I don't want anyone else to be able to get the lock on sem in between the time that the first thread executes doSomeWorkWithSharedObject() and the time the second executes doMoreWorkWithSameSharedObject(). Basically, I'm splitting one task into two parts. And the reason I'm splitting the task up is because (1) I want the first part of the task to get started as soon as possible, (2) I want to guarantee that the first part is complete before doTask() returns, and (3) I want the second, more time-consuming part of the task to be completed by another thread, possibly chosen from a pool of slave threads that are waiting around to finish tasks that have been started by master threads. NOTE: I recently posted this same question (sort of) here http://stackoverflow.com/questions/2754884/unlocking-a-mutex-from-a-different-thread-c but I confused mutexes with semaphores, and so the question about using boost locks didn't really get addressed.

Could anybody recommend an alternative method if it is bad? Thank-you.
