  • Why this code generates different numbers?

    - by frbry
    Hello, I have this function that creates a unique number for hard-disk and CPU combination. DWORD hw_hash() { char drv[4]; char szNameBuffer[256]; DWORD dwHddUnique; DWORD dwProcessorUnique; DWORD dwUniqueKey; char *sysDrive = getenv ("SystemDrive"); strcpy(drv, sysDrive); drv[2] = '\\'; drv[3] = 0; GetVolumeInformation(drv, szNameBuffer, 256, &dwHddUnique, NULL, NULL, NULL, NULL); SYSTEM_INFO si; GetSystemInfo(&si); dwProcessorUnique = si.dwProcessorType + si.wProcessorArchitecture + si.wProcessorRevision; dwUniqueKey = dwProcessorUnique + dwHddUnique; return dwUniqueKey; } It returns different numbers if I format my hard-disk and install a new Windows. Any ideas, why? Thank you. Edit: OK, Got it: This function returns the volume serial number that the operating system assigns when a hard disk is formatted. To programmatically obtain the hard disk's serial number that the manufacturer assigns, use the Windows Management Instrumentation (WMI) Win32_PhysicalMedia property SerialNumber. I should do more research before posting my problems online. Sorry to bother you, let's keep this here in case anybody else can need it.

  • iPhone - Developing on multiple Macs

    - by hecta
    I have a mac and a macbook, and one iPhone device and want to develop on both systems. My enrollment type is individual. How am I able to install the developer certificate and provisioning profiles on both machines? On the macbook it says 'a valid signing identity matching this profile could not be found in your keychain'. In my keychain I have a 'green status' for my developer certificate and in the xcode organizer for my device as well.

  • 405: Method Not Allowed WCF

    - by luiscarlosch
    I can perfectly call a WCF web method from localhost. I published to this server: http://luiscarlosch.com/WebFormClean.aspx (only firefox or chrome) with the Visual Studio publishing tool and it works fine. The problem is when a try to access it from another computer. I get the 405: Method Not Allowed. But It doest make sense because It works fine when i access it remotely from the publisher computer as I said. Any idea? [ServiceContract(Namespace = "")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class ContactProxy { [WebGet()] [OperationContract] public Contact getByID(int IDContact) { Contact contact = new Contact(IDContact); return contact; } [OperationContract] public EntityData insertEntityData(int IDEntityDataFieldType, int IDContact, String value) { //Contact contact = new Contact(); // contact.insertEntityData(IDEntityDataFieldType, IDContact, value); EntityData entityData = new EntityData(); entityData.save(IDEntityDataFieldType, IDContact, value); return entityData; } } Neither method seems to work. I just noticed some user were able to access http://luiscarlosch.com/WebFormClean.aspx because they change the values. So. some clients can read the methods but some cant. This should be happening.

  • Code behind methods vs. Jquery AJAX calls

    - by punkouter
    Theres a war brewing I can feel it! Old school coders are used to having every server control create events in the .cs files.. for example.. Getting the Initial load of data, Saving Data, Deleting data... and then binding datasources to the server control.. New school coders want to do it in Jquery + AJAX calls to .svc files... That gives automatic no post backs so that is a advantage... and I think its a different way of thinking.. All of a sudden the UI related events are all being done in Jquery.. What is the most modern and efficient way to go ? How can I convince the old school coders to let us you this new paradigm ? (assuming it is the better way)

  • Question regarding ip checksum code

    - by looktt
    unsigned short /* this function generates header checksums */ csum (unsigned short *buf, int nwords) { unsigned long sum; for (sum = 0; nwords > 0; nwords--) // add words(16bits) together sum += *buf++; sum = (sum >> 16) + (sum & 0xffff); //add carry over sum += (sum >> 16); //what does this step do??? add possible left-over //byte? But isn't it already added in the loop (if //any)? return ((unsigned short) ~sum); } I assume nwords in the number of 16bits word, not 8bits byte (if there are odd byte, nword is rounded to next large), is it correct? The line sum = (sum 16) + (sum & 0xffff) is to add carry over to make 16bit complement sum += (sum 16); What's the purpose of this step? Add left-over byte? How? Thanks!

  • Question about [Pure] methods

    - by devoured elysium
    Is the following method Pure? I'd say so, as it doesn't change in anyway the current class, thus, everything we can now currenly "see" in the class, before running this method will still be exactly the same after. Am I correct? class Set { ... public ISet<T> UnionWith(ISet<T> set) { ISet<T> unionSet = ... foreach (Element element in this) { unionSet.Add(element); } foreach (Element element in set) { unionSet.Add(element); } return unionSet; } }

  • Function call within XAML code?

    - by Matt H.
    I'd like to set a style on all my TextBox controls that does the following when it receives keyboard focus: 1) Change the background color 2) Call .SelectAll() to highlight all text I have this so far: <Style TargetType="TextBox"> <Style.Triggers> <Trigger Property="IsKeyboardFocusWithin" Value="True"> <Setter Property="Background"> <Setter.Value> <SolidColorBrush Color="#FFFFD1D9"/> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> Is there a way to also call .SelectAll() ? Thanks.

  • How can I automatically generate sql update scripts when some data is updated ?

    - by Brann
    I'd like to automatically generate an update script each time a value is modified in my database. In other words, if a stored procedure, or a query, or whatever updates column a with value b in table c (which as a pk column (i,j...k), I want to generate this : update c set a=b where i=... and j=... and k=... and store it somewhere (for example as a raw string in a table). To complicate things, I want the script to be generated only if the update has been made by a specific user. Good news is that I've got a primary key defined for all my tables. I can see how to do this using a trigger, but I would need to generate specific triggers for each table, and to update them each and every-time my schema changes. I guess there are some built-in ways to do this as SQL server sometimes need to store this kind of things (while using transactional replication for example), but couldn't find anything so far ... any ideas ? I'm also interested in ways to automatically generate triggers (probably using triggers - meta triggers, huh? - since I will need to update triggers automatically when the schema change)

  • Why does Module::Build's testcover gives me "use of uninitialized value" warnings?

    - by Kurt W. Leucht
    I'm kinda new to Module::Build, so maybe I did something wrong. Am I the only one who gets warnings when I change my dispatch from "test" to "testcover"? Is there a bug in Devel::Cover? Is there a bug in Module::Build? I probably just did something wrong. I'm using ActiveState Perl v5.10.0 with Module::Build version 0.31012 and Devel::Cover 0.64 and Eclipse 3.4.1 with EPIC 0.6.34 for my IDE. UPDATE: I upgraded to Module::Build 0.34 and the warnings are still output. *UPDATE: Looks like a bug in B::Deparse. Hope it gets fixed someday.* Here's my unit test build file: use strict; use warnings; use Module::Build; my $build = Module::Build->resume ( properties => { config_dir => '_build', }, ); $build->dispatch('test'); When I run this unit test build file, I get the following output: t\MyLib1.......ok t\MyLib2.......ok t\MyLib3.......ok All tests successful. Files=3, Tests=24, 0 wallclock secs ( 0.00 cusr + 0.00 csys = 0.00 CPU) But when I change the dispatch line to 'testcover' I get the following output which always includes a bunch of "use of uninitialized value in bitwise and" warning messages: Deleting database D:/Documents and Settings/<username>/My Documents/<SNIP>/cover_db t\MyLib1.......ok Use of uninitialized value in bitwise and (&) at D:/Perl/lib/B/Deparse.pm line 4252.

    - by andoriyu.mp
    I'm trying link 40 buttons to one event handler method and then do the processing work from one method instead of 40. I know how to link it but once I get there I don't know how to distinguish what button was pressed. Does anyone know how to reference the button object sender id or is there another way to solve this problem? Any help would be greatly appreciated.

  • Why is "copy and paste" of code dangerous?

    - by Yigang Wu
    Sometimes, my boss will complain us why we need so long time to implement a feature. Actually, the feature has been implemented in other AP before, you just need to copy and paste codes from there. The cost should be low. It's really a hard question, because copy and paste codes is not a easy thing from my point. Do you have any good reason to explain your boss who doesn't know technology?

  • WPF RadioButton selected in UI, but seen by code as IsChecked == false

    - by Mike
    I have some radio buttons in a group box. I select the buttons randomly, and all works perfectly from a visual standpoint and also the event handler is called each time a new button is selected. Now I have a dependency property with a callback when the value changes. When in this callback procedure I read the IsChecked value of any button, the value is False, in spite the button is visually selected (they are all false at the same time, strange). The debugger also displays all buttons unchecked. Hu hu, I'm lacking ideas about the reason, after the basic verifications... <GroupBox> <StackPanel> <RadioButton x:Name="btNone" Content="Disconnected" IsChecked="True" Checked="OnSelChecked"/> <RadioButton x:Name="btManual" Content="Manual" Checked="OnSelChecked"/> </StackPanel> </GroupBox> Event handler: private void OnSelChecked(object sender, RoutedEventArgs e) { if (btManual.IsChecked == true) { // is called } } Dependency property: public static readonly DependencyProperty ManualProperty = DependencyProperty.Register("Manual", typeof(Position), typeof(SwitchBox), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.AffectsRender, new PropertyChangedCallback(OnManualChanged))); Dependency property callback: private static void OnManualChanged(DependencyObject sender, DependencyPropertyChangedEventArgs args) { SwitchBox box = sender as SwitchBox; if (box.btManual.IsChecked == true) { // never true, why?? } }
