• Error_No_Token by adding printer driver (c#)

  - by user1686388

  I'm trying to add printer drivers using the windows API function AddPrinterDriver. The Win32 error 1008 (An attempt was made to reference a token that does not exist.) was always generated. My code is shown as following [DllImport("Winspool.drv")] static extern bool AddPrinterDriver(string Name, Int32 Level, [in] ref DRIVER_INFO_3 DriverInfo); [StructLayout(LayoutKind.Sequential)] public struct DRIVER_INFO_3 { public Int32 cVersion; public string Name; public string Environment; public string DriverPath; public string DataFile; public string ConfigFile; public string HelpFile; public string DependentFiles; public string MonitorName; public string DefaultDataType; } //....................... DRIVER_INFO_3 di = new DRIVER_INFO_3(); //...................... AddPrinterDriver(Environment.MachineName, 3, ref di); I have also tried to get a token by "ImpersonateSelf" before adding the printer driver. But the error 1008 insists. Does anyone have an idea? best regards.

• Weak hashmap with weak references to the values?

  - by Razor Storm

  I am building an android app where each entity has a bitmap that represents its sprite. However, each entity can be be duplicated (there might be 3 copies of entity asdf for example). One approach is to load all the sprites upfront, and then put the correct sprite in the constructors of the entities. However, I want to decode the bitmaps lazily, so that the constructors of the entities will decode the bitmaps. The only problem with this is that duplicated entities will load the same bitmap twice, using 2x the memory (Or n times if the entity is created n times). To fix this, I built a SingularBitmapFactory that will store a decoded Bitmap into a hash, and if the same bitmap is asked for again, will simply return the previously hashed one instead of building a new one. Problem with this, though, is that the factory holds a copy of all bitmaps, and so won't ever get garbage collected. What's the best way to switch the hashmap to one with weakly referenced values? In otherwords, I want a structure where the values won't be GC'd if any other object holds a reference to it, but as long as no other objects refers it, then it can be GC'd.

• jQuery Grouping Similar Items w/ Multidimensional Array

  - by NessDan

  So I have this structure setup: <ul> <li>http://www.youtube.com/watch?v=dw1Vh9Yzryo</li> (Vid1) <li>http://www.youtube.com/watch?v=bOF3o8B292U</li> (Vid2) <li>http://www.youtube.com/watch?v=yAY4vNJd7A8</li> (Vid3) <li>http://www.youtube.com/watch?v=yAY4vNJd7A8</li> <li>http://www.youtube.com/watch?v=dw1Vh9Yzryo</li> <li>http://www.youtube.com/watch?v=bOF3o8B292U</li> <li>http://www.youtube.com/watch?v=yAY4vNJd7A8</li> <li>http://www.youtube.com/watch?v=dw1Vh9Yzryo</li> </ul> Vid1 is repeated 3 times, Vid2 is repeated 3 times, and Vid3 is repeated 2 times. I want to put them into a structure where I can reference them like this: youtube[0][repeated] = 3; youtube[0][download] = "http://www.youtube.com/get_video?video_id=dw1Vh9Yzryo&fmt=36" youtube[1][repeated] = 3; youtube[1][download] = "http://www.youtube.com/get_video?video_id=bOF3o8B292U&fmt=36" youtube[2][repeated] = 3; youtube[2][download] = "http://www.youtube.com/get_video?video_id=yAY4vNJd7A8&fmt=36" "This video was repeated " + youtube[0][repeated] + " times and you can download it here: " + youtube[0][download]; How can I set this multidimensional array up? Been Googling for hours and I don't know how to set it up. Can anyone help me out?

• drupal themes: .info file: how do I add more than 1 css file / js file to my theme?

  - by egarcia

  I'm creating a new Drupal theme. Until now, I only needed to include a single css file and a single js file. So my theme.info file had something like this: stylesheets[all][] = css/style.css scripts[] = js/script.js Now I must include jquery and jquery-ui in order to use a calendar date. These come with 2 new javascript files, and 1 additonal css file that I must add to the site. The calendar input form is going to be used in all pages (on a side block) so it is ok for me to load the extra css/javascript on all pages. I think the easiest thing would be to reference them on the .info file itself. At first I tried to just put them there with separate spaces: stylesheets[all][] = css/style.css css/ui-lightness/jquery-ui-1.8.1.custom.css scripts[] = js/jquery-1.4.2.min.js js/jquery-ui-1.8.1.custom.min.js js/reservations.js I emptied drupal's cache and... none of them loaded. I then tried separating each file with a comma, and flushing the cache again. Same result. I've browsed some drupal pages, but could not find how to add several javascript/css files on one theme (they always seem to add just 1 of each). So, how do I include several css/javascript files on the .info file?

• Linker error: wants C++ virtual base class destructor

  - by jdmuys

  Hi, I have a link error where the linker complains that my concrete class's destructor is calling its abstract superclass destructor, the code of which is missing. This is using GCC 4.2 on Mac OS X from XCode. I saw http://stackoverflow.com/questions/307352/g-undefined-reference-to-typeinfo but it's not quite the same thing. Here is the linker error message: Undefined symbols: "ConnectionPool::~ConnectionPool()", referenced from: AlwaysConnectedConnectionZPool::~AlwaysConnectedConnectionZPool()in RKConnector.o ld: symbol(s) not found collect2: ld returned 1 exit status Here is the abstract base class declaration: class ConnectionPool { public: static ConnectionPool* newPool(std::string h, short p, std::string u, std::string pw, std::string b); virtual ~ConnectionPool() =0; virtual int keepAlive() =0; virtual int disconnect() =0; virtual sql::Connection * getConnection(char *compression_scheme = NULL) =0; virtual void releaseConnection(sql::Connection * theConnection) =0; }; Here is the concrete class declaration: class AlwaysConnectedConnectionZPool: public ConnectionPool { protected: <snip data members> public: AlwaysConnectedConnectionZPool(std::string h, short p, std::string u, std::string pw, std::string b); virtual ~AlwaysConnectedConnectionZPool(); virtual int keepAlive(); // will make sure the connection doesn't time out. Call regularly virtual int disconnect(); // disconnects/destroys all connections. virtual sql::Connection * getConnection(char *compression_scheme = NULL); virtual void releaseConnection(sql::Connection * theConnection); }; Needless to say, all those members are implemented. Here is the destructor: AlwaysConnectedConnectionZPool::~AlwaysConnectedConnectionZPool() { printf("AlwaysConnectedConnectionZPool destructor call"); // nothing to destruct in fact } and also maybe the factory routine: ConnectionPool* ConnectionPool::newPool(std::string h, short p, std::string u, std::string pw, std::string b) { return new AlwaysConnectedConnectionZPool(h, p, u, pw, b); } I can fix this by artificially making my abstract base class concrete. But I'd rather do something better. Any idea? Thanks

• Unattended Install of SQL Server 2005 Express with LOCAL Server InstanceName

  - by Jeff

  I'm creating an install package using InnoSetup and installing SQL Server 2005 Express. Here's the code below that appears in my RUN section: Filename: "{app}\SQL Server 2005 Express\SQLEXPR.exe" ; Parameters: "-q /norebootchk /qn reboot=ReallySuppress addlocal=all INSTANCENAME=(LOCAL) SCCCHECKLEVEL=IncompatibleComponents:1;MDAC25Version:0 ERRORREPORTING=2 SQLAUTOSTART=1 SAPWD=passwordhere SECURITYMODE=SQL"; WorkingDir: {app}\SQL Server 2005 Express; StatusMsg: Installing Microsoft SQL Server 2005 Express... Please Wait...;Check:SQLVerifyInstall What I'm trying to accomplish is have the SQL Server package install but only have the instance name itself reference the name of the machine name and nothing more. What I'm receiving instead is a named instance instead of local such as MachineName\SQLEXPRESS which is not what I want to receive. I need a local instance instead of a named instance due to the way my code is written to be able to install and talk with the databases in question. I would change it, trust me, were it not the fact that this install package is a replacement to a previous package that used the MSDE installer. I have to be able to support both through code. Any suggestions are welcome but a clear and concise method to get the installer to quietly install using only the machine name is my main goal. Thanks for the help and support!

• Cocoa framework development: sharing between projects

  - by e.James

  I am currently developing a handful of similar Cocoa desktop apps. In an effort to share code between them, I have identified a set of core classes and functions that can be common across all of these applications. I would like to bundle this common code into a framework which all of my current applications (and any future ones) can link against. Now, here's the hard part: I'm going to be developing this framework as I go, so I need each of my desktop apps to have a reference to it, but I want to be able to edit the framework source code from within each of the app projects and have the framework automatically rebuilt as required. For example, let's say I have the Xcode project for DesktopAppNumberOne open, and I decide that one of my framework classes needs to be changed. I would like to: Open and edit the source file for that framework class without having to open the framework project in Xcode. Hit "build" on DesktopAppNumberOne, and see the framework rebuilt first (because one of its sources has changed), then see parts of DesktopAppNumberOne rebuilt (because one of the frameworks it links against has changed). I can see how to do this with only one app and one framework, but I'm having trouble figuring out how to do it with multiple apps that share a single framework. Has anyone had success with this approach? Am I perhaps going about this the wrong way? Any help would be appreciated.

• How to find which file is open in eclipse editor without using IEditorPart?

  - by Destructor

  I want to know which file (or even project is enough) is opened in eclipse editor? I know we can do this once we get IEditorPart from doSetInput method, IFile file = ((IFileEditorInput) iEditorPart).getFile(); But I want the name of file without using IEditorPart, how can I do the same? Checking which is the selected file in project explorer is not of much help because, user can select multiple files at once and open all simultaneously and I did not way to distinguish which file opened at what time. Adding more info: I have an editor specified for a particular type of file, now every time it opens, during intializing editor I have some operation to do based on project properties. While initializing editor, I need the file handle (of the one which user opened/double clicked) or the corresponding project handle. I have my editor something this way: public class MyEditor extends TextEditor{ @Override protected void initializeEditor() { setSourceViewerConfiguration(new MySourceViewerConfiguration( CDTUITools.getColorManager(), store, "MyPartitions", this)); } //other required methods @Override protected void doSetInput(IEditorInput input) throws CoreException { if(input instanceof IFileEditorInput) { IFile file = ((IFileEditorInput) input).getFile(); } } } as I have done in the doSetInput() method , I want the file handle(even project handle is sufficient). But the problem is in initializeEditor() function there is no reference to editorInput, hence I am unable to get the file handle. In the source viewer configuration file, I set the code scanners and this needs some project specific information that will set the corresponding rules.

• structDelete doesn't affect the shallow copy?

  - by Travis

  I was playing around onError so I tried to create an error using a large xml document object. <cfset XMLByRef = variables.parsedXML.XMLRootElement.XMLChildElement> <cfset structDelete(variables.parsedXML, "XMLRootElement")> <cfset startXMLShortLoop = getTickCount()> <cfloop from = "1" to = "#arrayLen(variables.XMLByRef)#" index = "variables.i"> <cfoutput>#variables.XMLByRef[variables.i].id.xmltext#</cfoutput><br /> </cfloop> <cfset stopXMLShortLoop = getTickCount()> I expected to get an error because I deleted the structure I was referencing. From LiveDocs: Variable Assignment - Creates an additional reference, or alias, to the structure. Any change to the data using one variable name changes the structure that you access using the other variable name. This technique is useful when you want to add a local variable to another scope or otherwise change a variable's scope without deleting the variable from the original scope. instead I got 580df1de-3362-ca9b-b287-47795b6cdc17 25a00498-0f68-6f04-a981-56853c0844ed ... ... ... db49ed8a-0ba6-8644-124a-6d6ebda3aa52 57e57e28-e044-6119-afe2-aebffb549342 Looped 12805 times in 297 milliseconds <cfdump var = "#variables#"> Shows there's nothing in the structure, just parsedXML.xmlRoot.xmlName with the value of XMLRootElement. I also tried <cfset structDelete(variables.parsedXML.XMLRootElement, "XMLChildElement")> as well as structClear for both. More information on deleting from the xml document object. http://help.adobe.com/en_US/ColdFusion/9.0/Developing/WSc3ff6d0ea77859461172e0811cbec22c24-78e3.html Can someone please explain my faulty logic?

• Help ! How do I get the total number rows from my SQL Server paging procedure ?

  - by The_AlienCoder

  Ok I have a table in my SQL Server database that stores comments. My desire is to be able to page though the records using [Back],[Next], page numbers & [Last] buttons in my data list. I figured the most efficient way was to use a stored procedure that only returns a certain number of rows within a particular range. Here is what I came up with @PageIndex INT, @PageSize INT, @postid int AS SET NOCOUNT ON begin WITH tmp AS ( SELECT comments.*, ROW_NUMBER() OVER (ORDER BY dateposted ASC) AS Row FROM comments WHERE (comments.postid = @postid)) SELECT tmp.* FROM tmp WHERE Row between (@PageIndex - 1) * @PageSize + 1 and @PageIndex*@PageSize end RETURN Now everything works fine and I have been able implement [Next] and [Back] buttons in my data list pager. Now I need the total number of all comments (not in the current page) so that I can implement my page numbers and the[Last] button on my pager. In other words I want to return the total number of rows in my first select statement i.e WITH tmp AS ( SELECT comments.*, ROW_NUMBER() OVER (ORDER BY dateposted ASC) AS Row FROM comments WHERE (comments.postid = @postid)) set @TotalRows = @@rowcount @@rowcount doesn't work and raises an error. I also cant get count.* to work either. Is there another way to get the total amount of rows or is my approach doomed.

• C++ operator lookup rules / Koenig lookup

  - by John Bartholomew

  While writing a test suite, I needed to provide an implementation of operator<<(std::ostream&... for Boost unit test to use. This worked: namespace theseus { namespace core { std::ostream& operator<<(std::ostream& ss, const PixelRGB& p) { return (ss << "PixelRGB(" << (int)p.r << "," << (int)p.g << "," << (int)p.b << ")"); } }} This didn't: std::ostream& operator<<(std::ostream& ss, const theseus::core::PixelRGB& p) { return (ss << "PixelRGB(" << (int)p.r << "," << (int)p.g << "," << (int)p.b << ")"); } Apparently, the second wasn't included in the candidate matches when g++ tried to resolve the use of the operator. Why (what rule causes this)? The code calling operator<< is deep within the Boost unit test framework, but here's the test code: BOOST_AUTO_TEST_SUITE(core_image) BOOST_AUTO_TEST_CASE(test_output) { using namespace theseus::core; BOOST_TEST_MESSAGE(PixelRGB(5,5,5)); // only compiles with operator<< definition inside theseus::core std::cout << PixelRGB(5,5,5) << "\n"; // works with either definition BOOST_CHECK(true); // prevent no-assertion error } BOOST_AUTO_TEST_SUITE_END() For reference, I'm using g++ 4.4 (though for the moment I'm assuming this behaviour is standards-conformant).

• Update Options on Existing jQuery Object

  - by Vince Kronlein

  I'm using Bootstrap and DataTables in my app and I have a default initializer for tables based on class. I can just add the class data-table to the table and it gets instantiated with the default values I want. I'd like to know how to change or update specific options based on a specific table. if ($.fn.dataTable) { $('.data-table').dataTable( { sDom: "R<'row'<'span6'l><'span6'f>r>t<'row'<'span6'i><'span6'p>>", sPaginationType: "bootstrap", oLanguage: { "sLengthMenu": "_MENU_ &nbsp; records per page" }, aoColumnDefs: [ { "bSortable": false, "aTargets": [ 0 ] } ] }); } All my data tables have a checkbox in the first column so the above removal of sorting works for all of them. But I'd like to be able to update the aoColumnDefs on a table by table basis so I can add other columns that I don't want sorted. So let's say I have a table: $('#member-list'), how do I access this object and update it's datatables options in jQuery? I can't find any reference or help anywhere. Thanks a lot! -V

• datareader.close is called in if - else branching. How to validate datareader is actually closed usi

  - by tanmay

  Hi, I have written couple of custom rules in for fxcop 1.36. I have written a code to find weather opened datareader is closed or not. But it does not check which datareader object is calling the close() method so I can't be sure if all opened datareader objs are closed!! 2nd: if I am using data reader in IF else like if 1=2 dr = cmd.executeReader(); else dr = cmd2.execureReader(); end if in this case it will search for 2 datareader objects to be closed.. I am putting my code for more clarity. public override ProblemCollection Check(Member member) { Method method = member as Method; int countCatch =0; int countErrLog = 0; Instruction objInstr = null; if (method != null) { for (int i = 0; i < method.Instructions.Count; i++) { objInstr = method.Instructions[i]; if (objInstr.Value != null) { if (objInstr.Value.ToString().Contains("System.Data.SqlClient.SqlDataReader")) { countCatch += 1; } if (countCatch>0) { if (objInstr.Value.ToString().Contains("System.Data.SqlClient.SqlDataReader.Close")) { countErrLog += 1; } } } } } if (countErrLog!=countCatch) { Resolution resolu = GetResolution(new string[] { method.ToString() }); Problems.Add(new Problem(resolu)); } return Problems; Thanks and regards, Tanmay.

• Set ContentTemplate in CodeBehind: XamlParseException 2260 Error

  - by user362215

  Hi, I'd like to change the ContentTemplate of a ContentPresenter in the CodeBehind file. But if I run the Silverlight 4 application a XamlParseException with the error code 2260 occures. foreach (ContentPresenter item in Headers) { item.ContentTemplate = Parent.UnselectedHeaderTemplate; } if ((index >= 0) && (index < Headers.Count)) { ContentPresenter item0 = (ContentPresenter)Headers[index]; item0.ContentTemplate = Parent.SelectedHeaderTemplate; } If I do only the foreach code without the code in the "if", it works. And if I only do the code in the "if" without the foreach it works too. But togheter (the "if"-code and the foreach-code) it doesn't work. I have no idea why it doesn't work. The two templates look like this: <Setter Property="UnselectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="#FF999999" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> <!-- SelectedHeader template --> <Setter Property="SelectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="{TemplateBinding Foreground}" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> If you have an idea what problem is please tell me.

• Help with GetGlyphOutline function(WinAPI)

  - by user146780

  I want to use this function to get contours and within these contours, I want to get cubic bezier. I think I have to call it with GGO_BEZIER. What puzzles me is how the return buffer works. "A glyph outline is returned as a series of one or more contours defined by a TTPOLYGONHEADER structure followed by one or more curves. Each curve in the contour is defined by a TTPOLYCURVE structure followed by a number of POINTFX data points. POINTFX points are absolute positions, not relative moves. The starting point of a contour is given by the pfxStart member of the TTPOLYGONHEADER structure. The starting point of each curve is the last point of the previous curve or the starting point of the contour. The count of data points in a curve is stored in the cpfx member of TTPOLYCURVE structure. The size of each contour in the buffer, in bytes, is stored in the cb member of TTPOLYGONHEADER structure. Additional curve definitions are packed into the buffer following preceding curves and additional contours are packed into the buffer following preceding contours. The buffer contains as many contours as fit within the buffer returned by GetGlyphOutline." I'm really not sure how to access the contours. I know that I can change a pointer another type of pointer but i'm not sure how I go about getting the contours based on this documentation. Thanks

• How does Amazon's Statistically Improbable Phrases work?

  - by ??iu

  How does something like Statistically Improbable Phrases work? According to amazon: Amazon.com's Statistically Improbable Phrases, or "SIPs", are the most distinctive phrases in the text of books in the Search Inside!™ program. To identify SIPs, our computers scan the text of all books in the Search Inside! program. If they find a phrase that occurs a large number of times in a particular book relative to all Search Inside! books, that phrase is a SIP in that book. SIPs are not necessarily improbable within a particular book, but they are improbable relative to all books in Search Inside!. For example, most SIPs for a book on taxes are tax related. But because we display SIPs in order of their improbability score, the first SIPs will be on tax topics that this book mentions more often than other tax books. For works of fiction, SIPs tend to be distinctive word combinations that often hint at important plot elements. For instance, for Joel's first book, the SIPs are: leaky abstractions, antialiased text, own dog food, bug count, daily builds, bug database, software schedules One interesting complication is that these are phrases of either 2 or 3 words. This makes things a little more interesting because these phrases can overlap with or contain each other.

• scanf a byte then print it out?

  I've searched around to see if I can find this answer but I can't seem to (please let me know if I'm wrong). I am trying to use scanf to read in a byte, an unsigned int and a char in one .c file and I am trying to access this byte in a different .c file and print it out.

• Problem with jquery #find on partial postback

  - by anonymous

  I have a third party component. It is a calendar control. I have a clientside event on it which fires javascript to show a popup menu. I do everything client side so I can use MVC. dd function MouseDown(oDayView, oEvent, element) { try { e = oEvent.event; var rightClick = (e.button == 2); if (rightClick) { var menu = $find("2_menuSharedCalPopUp"); menu.showAt(200, 200, e); } } catch (err) { alert("MouseDown() err: " + err.description); } } The javascript fires perfectly withe $find intially. I have another clientside method which updates the calendar via a partial postback. Once I have done this all subsequent MouseDowns( rightclicks) which use the $find statment error with 'null'. All similar problems people have out there seem to be around calling javascript after a postback - with solutions being re-registering an event using PageRequestManager or registering a clientside function on the server - et cetera. However, the event is firing, and the javascript working - it's the reference in the DOM that seems an issue. Any ideas?

  I have an application that downloads an xml file, parses the file, and creates core data objects while doing so. In the parse code I have a function called 'emptydatacontext' that removes all items from Core Data before creating replacements from the xml file. This method looks like this: -(void) emptyDataContext { NSMutableArray* mutableFetchResults = [CoreDataHelper getObjectsFromContext:@"Condition" :@"road" :NO :managedObjectContext]; NSFetchRequest * allCon = [[NSFetchRequest alloc] init]; [allCon setEntity:[NSEntityDescription entityForName:@"Condition" inManagedObjectContext:managedObjectContext]]; NSError * error = nil; NSArray * conditions = [managedObjectContext executeFetchRequest:allCon error:&error]; [allCon release]; for (NSManagedObject * condition in conditions) { [managedObjectContext deleteObject:condition]; } } The first time this runs it deletes all objects and functions as it should - creating new objects from the xml file. I created a 'update' button that starts the exact same process of retrieving the file the preceeding as it did the first time. All is well until its time to delete the core data objects again. This 'deleteObject' call creates a "EXC_BAD_ACCESS" error each time. This only happens on the second time through. See this image for the debugger window as it appears when walking through the deletion FOR loop on the second iteration. Conditions is the fetched array of 7 objects with the objects below. Condition should be an individual condition. link text As you can see 'condition' does not match any of the objects in the 'conditions' array. I'm sure this is why I'm getting the memory access errors. Just not sure why this fetch (or the FOR) is returning a wrong reference. All the code that successfully performes this function on the first iteration is used in the second but with very different results. Thanks in advance for the help!

• Flex : providing data with a PHP Class

  - by Tristan

  Hello, i'm a very new user to flex (never use flex, nor flashbuilder, nor action script before), but i want to learn this langage because of the beautiful RIA and chart it can do. I watched the video on adobe : 1 hour to build your first program but i'm stuck : On the video it says that we have to provide a PHP class for accessing data and i used the example that flash builder gave (with zend framework and mysqli). I never used those ones and it makes a lot to learn if i count zen + mysqli. My question is : can i use a PHP class like this one ? What does flash builder except in return ? i hear that was automatic. example it may be wrong, i'm not very familiar with classes when acessing to database : <?php class DBConnection { protected $server = "localhost"; protected $username = "root"; protected $password = "root"; protected $dbname = "something"; protected $connection; function __construct() { $this->connection = mysql_connect($this->server, $this->username, $this->password); mysql_select_db($this->dbname,$this->connection); mysql_query("SET NAMES 'utf8'", $this->connection); } function query($query) { $result = mysql_query($query, $this->connection); if (!$result) { echo 'request error ' . mysql_error($this->connection); exit; } return $result; } function getAll() { $req = "select * from servers"; $result = query($req) return $result } function num_rows() { return mysql_num_rows($result); } function end() { mysql_close($this->connection); } } ?> Thank you,

• How to detect that the internet connection has got disconnected through a java desktop application?

  - by Yatendra Goel

  I am developing a Java Desktop Application that access internet. It is a multi-threaded application, each thread do the same work (means each thread is an instance of same Thread class). Now, as all the threads need internet connection to be active, there should be some mechanism that detects whether an internet connection is active or not. Q1. How to detect whether the internet connection is active or not? Q2. Where to implement this internet-status-check-mechanism code? Should I start a separate thread for checking internet status regularly and notifies all the threads when the status changes from one state to another? Or should I let each thread check for the internet-status itself? Q3. This issue should be a very common issue as every application accessing an internet should deal with this problem. So how other developers usually deal with this problem? Q4. If you could give me a reference to a good demo application that addresses this issue then it would greatly help me.

• Get more error information from unhandled error

  - by Andrew Simpson

  I am using C# in a desktop application. I am calling a DLL written in C that I do not have the source code for. Whenever I call this DLL I get an untrapped error which I trap in an UnhandledException event/delegate. The error is : object reference not set to an instance of an object But the stack trace is empty. When I Googled this the info back was that the error was being hanlded eleswhere and then rethrown. But this can only be in the DLL I do not have the source code for. So, is there anyway I can get more info about this error? This is my code... in program.cs... AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { try { Exception _ex = (Exception)e.ExceptionObject; //the stact trace property is empty here.. } finally { Application.Exit(); } } My DLL... [DllImport("AutoSearchDevice.dll", EntryPoint = "Start", ExactSpelling = false, CallingConvention = CallingConvention.StdCall)] public static extern int Start(int ASD_HANDLE); An I call it like so: public static void AutoSearchStart() { try { Start(m_pASD); } catch (Exception ex) { } }
