  • Reading from the Registry in ASP.NET

    - by Filip Ekberg
    I have a Library ( DLL ) that has a method with the following: var masterKey = Registry. LocalMachine. OpenSubKey("SOFTWARE\\Microsoft\\Dynamics\\5.0\\"); When running this method in an WinForms applicaiton, masterKey is not null and when running this in asp.net masterKey is null! I've checked the executing user with WindowsIdentity.GetCurrent().Name and the same user is executing both applications. The asp.net application is executed in visual studio ( debug: F5 ) and so is the WinForms application. How come I cannot read the key in asp.net?

  • How to get video file details eg. duration in Android?

    - by spirytus
    I struggle to get specific video file details so duration etc. from the file the files recorded earlier. All I can currently do is to get cursor with all the files, then loop one by one. Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), MediaStore.Video.Media.EXTERNAL_CONTENT_URI, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); if(cursor.moveToFirst()) while(!cursor.isLast()){ if(cursor.getString(3)==fight.filename) { // do something here } cursor.moveToNext(); } I need however to access details of specific files so I tried to create URI but no luck as cursor returned is always null. Where do I go wrong? Uri uri = Uri.parse(Environment.DIRECTORY_DCIM+"/FightAll_BJJ_Scoring/"+(fight.filename)); Cursor cursor = MediaStore.Video.query(getContext().getContentResolver(), uri, new String[]{MediaStore.Video.VideoColumns.DURATION,MediaStore.Video.VideoColumns.DATE_TAKEN,MediaStore.Video.VideoColumns.RESOLUTION,MediaStore.Video.VideoColumns.DISPLAY_NAME}); // cursor is always null here

  • Strcpy() corrupts the copied string in Solaris but not Linux

    - by strictlyrude27
    Hi all, I'm writing a C code for a class. This class requires that our code compile and run on the school server, which is a sparc solaris machine. I'm running Linux x64. I have this line to parse (THIS IS NOT ACTUAL CODE BUT IS INPUT TO MY PROGRAM): while ( cond1 ){ I need to capture the "while" and the "cond1" into separate strings. I've been using strtok() to do this. In Linux, the following lines: char *cond = NULL; cond = (char *)malloc(sizeof(char)); memset(cond, 0, sizeof(char)); strcpy(cond, strtok(NULL, ": \t\(){")); //already got the "while" out of the line will correctly capture the string "cond1".Running this on the solaris machine, however, gives me the string "cone1". Note that in plenty of other cases within my program, strings are being copied correctly. (For instance, the "while") was captured correctly. Does anyone know what is going on here?

  • NAudio: How can I get an event that tells me that the MP3 file reached the end?

    - by Rookian
    I tried to use this: private void CreateDevice() { _playbackDevice = new WaveOut(); _playbackDevice.PlaybackStopped += PlaybackDevicePlaybackStopped; } void PlaybackDevicePlaybackStopped(object sender, EventArgs e) { if (OnPlaybackStopped != null) { OnPlaybackStopped(this, e); } } But it never invoked. Then I tried to use the PlaybackState by polling the property with a timer: public PlaybackState PlaybackState { get { if (_playbackDevice == null) return default(PlaybackState); return _playbackDevice.PlaybackState; } } But when the song ends it does not change to "stopped". But when I call Stopped it changes correctly. Can someone help me?

  • Stop propagating deletes

    - by Mark
    Is it just me or is anyone else finding EF very difficult to use in a real app :( I'm using it as the data layer and have created custom business objects. I'm having difficulty converting the business objects back to EF objects and updating/adding/deleting from the database. Does anyone know a good, simple example of doing this? Actually the current problem that's driving me nuts is when I delete something EF tries to delete other related stuff as well. For example, if I delete an invoice it will also delete the associated customer! Seems odd. I can't figure out how to stop it doing this. // tried: invoiceEfData.CustomerReference = null; // also tried invoiceEfData.Customer = null; context.DeleteObject(invoiceEfData); context.SaveChanges(); // at this point I get a database error due to it attempting to delete the customer

  • C# WMI Process Differentiation!?

    - by Goober
    Scenario I have a method that returns a list of processes using WMI. If I have 3 processes running (all of which are C# applications) - and they all have THE SAME PROCESS NAME but different command line arguments, how can I differentiate between them If I want to start them or terminate them!? Thoughts As far as I can see, I physically cannot differentiate between them, at least not without having to use the Handle, but that doesn't tell me which one of them got terminated because the others will still sit there with the same name........ ....really stumped, help greatly appreciated!

  • Adding STI to Existing Table...

    - by keruilin
    I want to add STI to an existing table using a custom type column. Let's call this taste_type whose corresponding model is Fruit. In the Fruit model I have: set_inheritance_column :taste_type In my migration to add STI I have: class AddSTI < ActiveRecord::Migration def self.up add_column :fruits, :taste_type, :string, :limit => 100, :null => false Fruit.reset_column_information Fruit.find_by_id(1).update_attributes({:taste_type => 'Sour'}) end def self.down remove_column :fruits, :taste_type end end When I run the migration, I get the following error: Mysql::Error: Column 'taste_type' cannot be null: ... Any idea what's going? I can get the migration to run if I comment the set_inheritance_column in the Fruit model, then uncomment it after I run the migration. Obviously, I don't want to do this, however.

  • Catch not working and how to unset the exception handler

    - by neoneye
    catch is not working because there is installed an exception handler using set_exception_handler() I need "catch" to work, so I guess I need to unset the exception handler somehow. Things such as set_exception_handler(NULL) isn't working. Any ideas how to unset the exception handler? function my_exception_handler($exception) { error_log("caught exception: " . $exception->getMessage() ); } set_exception_handler("my_exception_handler"); // QUESTION: how does on unset it ? //set_exception_handler(NULL); try { throw new Exception('hello world'); error_log("should not happen"); } catch(Exception $e) { error_log("should happen: " . $e->getMessage()); } Actual output: caught exception: hello world Desired output: should happen: hello world

  • How to make linq master detail query for 0..n relationship?

    - by JK
    Given a classic DB structure of Orders has zero or more OrderLines and OrderLine has exactly one Product, how do I write a linq query to express this? The output would be OrderNumber - OrderLine - Product Name Order-1 null null // (this order has no lines) Order-2 1 Red widget I tried this query but is not getting the orders with no lines var model = (from po in Orders from line in po.OrderLines select new { OrderNumber = po.Id, OrderLine = line.LineNumber, ProductName = line.Product.ProductDescription, } ) I think that the 2nd from is limiting the query to only those that have OrderLines, but I dont know another way to express it. LINQ is very non-obvious if you ask me!

  • How do I catch the error from my printer with PrintDocument?

    - by Scottie
    I am using the PrintDocument class to print to my Brother label printer. When I execute the Print() method, the printer starts flashing a red error light, but everything else returns successful. I can run this same code on my laser printer and everything works fine. How can I see what is causing the error on my label printer? Code: public class Test { private Font printFont; private List<string> _documentLinesToPrint = new List<string>(); public void Run() { _documentLinesToPrint.Add("Test1"); _documentLinesToPrint.Add("Test2"); printFont = new Font("Arial", 10); var pd = new PrintDocument(); pd.DefaultPageSettings.Margins = new Margins(25, 25, 25, 25); pd.DefaultPageSettings.PaperSize = new PaperSize("Label", 400, 237); var printerSettings = new System.Drawing.Printing.PrinterSettings(); printerSettings.PrinterName ="Brother QL-570 LE"; pd.PrinterSettings = printerSettings; pd.PrinterSettings.Copies = 1; pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage); pd.Print(); } // The PrintPage event is raised for each page to be printed. private void pd_PrintPage(object sender, PrintPageEventArgs ev) { float linesPerPage = 0; float yPos = 0; int count = 0; float leftMargin = ev.MarginBounds.Left; float topMargin = ev.MarginBounds.Top; string line = null; // Calculate the number of lines per page. linesPerPage = ev.MarginBounds.Height / printFont.GetHeight(ev.Graphics); // Print each line of the file. while ((count < linesPerPage) && (count < _documentLinesToPrint.Count)) { line = _documentLinesToPrint[count]; yPos = topMargin + (count * printFont.GetHeight(ev.Graphics)); ev.Graphics.DrawString(line, printFont, Brushes.Black, leftMargin, yPos, new StringFormat()); line = null; count++; } // If more lines exist, print another page. if (line != null) ev.HasMorePages = true; else ev.HasMorePages = false; } }

  • mx:Tree not dispatching "itemClick" event when click on icon

    - by Xshare
    I have a flex tree that worked perfectly fine when we set the defaultLeafIcon={null} and the folderClosedIcon and folderOpenIcon to {null}. We decided to put the icons back in and took out the nulls. Now they show up fine, but if you click on the icon instead of the label or the rest of the row, it seems to change the selected item, shows the highlight around the new item, but doesn't dispatch the ItemClick event. This makes it really hard to know that the tree's selected item has changed! The weird part is that once you have clicked on the icon once and it looked like the selectedItem changed (or at least it applied that style), if you click the same icon again, it will actually fire the itemClick event. if you click any other icon, it does the same thing again, switching the selectedItem and styling that row, but not firing the itemClick event. Any ideas? Thanks. (This is in flex 4 btw)

  • VerifyError When Running jUnit Test on Android 1.6

    - by DKnowles
    Here's what I'm trying to run on Android 1.6: package com.healthlogger.test; public class AllTests extends TestSuite { public static Test suite() { return new TestSuiteBuilder(AllTests.class).includeAllPackagesUnderHere().build(); } } and: package com.healthlogger.test; public class RecordTest extends AndroidTestCase { /** * Ensures that the constructor will not take a null data tag. */ @Test(expected=AssertionFailedError.class) public void testNullDataTagInConstructor() { Record r = new Record(null, Calendar.getInstance(), "Data"); fail("Failed to catch null data tag."); } } The main project is HealthLogger. These are run from a separate test project (HealthLoggerTest). HealthLogger and jUnit4 are in HealthLoggerTest's build path. jUnit4 is also in HealthLogger's build path. The class "Record" is located in com.healthlogger. Commenting out the "@Test..." and "Record r..." lines allows this test to run. When they are uncommented, I get a VerifyError exception.

  • TreeMap randomly stops properly returning values

    - by smessing
    I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else ever encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

  • WaitForSingleObject( )

    I have got myself stuck into a really amazing issue here.The code is like as below. class A { public: A(){ m_event = CreateEvent(NULL, false, false, NULL); // create an event with initial value as non-signalled m_thread = _beginthread(StaticThreadEntry, 0, this); // create a thread } static void StaticThreadEntry(A * obj) { obj->ThreadEntry(); } void ThreadEntry(); }; void A::ThreadEntry() { WaitforSingleObject(m_event,INFINITE); } int main() { A a; SetEvent(m_event); // sets the event to signalled state which causes the running thread to terminate WaitForSingleObject(m_thread, INFINITE); // waits for the thread to terminate return 0; } Problem : When the above code is run,sometimes( 1 out of 5 ) it hangs and the control gets stuck in the call to WaitforSingleObject()( inside the main function ).The code always calls SetEvent() function to ensure that the thread would terminate before calling Wait() function. I do not see any reason why it should ever hang?

  • Is Java assert broken?

    - by BlairHippo
    While poking around the questions, I recently discovered the assert keyword in Java. At first, I was excited. Something useful I didn't already know! A more efficient way for me to check the validity of input parameters! Yay learning! But then I took a closer look, and my enthusiasm was not so much "tempered" as "snuffed-out completely" by one simple fact: you can turn assertions off.* This sounds like a nightmare. If I'm asserting that I don't want the code to keep going if the input listOfStuff is null, why on earth would I want that assertion ignored? It sounds like if I'm debugging a piece of production code and suspect that listOfStuff may have been erroneously passed a null but don't see any logfile evidence of that assertion being triggered, I can't trust that listOfStuff actually got sent a valid value; I also have to account for the possibility that assertions may have been turned off entirely. And this assumes that I'm the one debugging the code. Somebody unfamiliar with assertions might see that and assume (quite reasonably) that if the assertion message doesn't appear in the log, listOfStuff couldn't be the problem. If your first encounter with assert was in the wild, would it even occur to you that it could be turned-off entirely? It's not like there's a command-line option that lets you disable try/catch blocks, after all. All of which brings me to my question (and this is a question, not an excuse for a rant! I promise!): What am I missing? Is there some nuance that renders Java's implementation of assert far more useful than I'm giving it credit for? Is the ability to enable/disable it from the command line actually incredibly valuable in some contexts? Am I misconceptualizing it somehow when I envision using it in production code in lieu of statements like if (listOfStuff == null) barf();? I just feel like there's something important here that I'm not getting. *Okay, technically speaking, they're actually off by default; you have to go out of your way to turn them on. But still, you can knock them out entirely.
