• Satisfying indirect references at runtime.

  - by automatic

  I'm using C# and VS2010. I have a dll that I reference in my project (as a dll reference not a project reference). That dll (a.dll) references another dll that my project doesn't directly use, let's call it b.dll. None of these are in the GAC. My project compiles fine, but when I run it I get an exception that b.dll can't be found. It's not being copied to the bin directory when my project is compiled. What is the best way to get b.dll into the bin directory so that it can be found at run time. I've thought of four options. Use a post compile step to copy b.dll to the bin directory Add b.dll to my project (as a file) and specify copy to output directory if newer Add b.dll as a dll reference to my project. Use ILMerge to combine b.dll with a.dll I don't like 3 at all because it makes b.dll visible to my project, the other two seem like hacks. Am I missing other solutions? Which is the "right" way? Would a dependency injection framework be able to resolve and load b.dll?

• Compression Program in C

  - by Delandilon

  I want to compress a series of characters. For example if i type Input : FFFFFBBBBBBBCCBBBAABBGGGGGSSS (27 x 8 bits = 216 bits) Output: F5B7C2B3A2B2G5S3 (14 x 8 bits = 112bits) So far this is what i have, i can count the number of Characters in the Array. But the most important task is to count them in the same sequence. I can't seem to figure that out :( Ive stared doing C just a few weeks back, i have knowledge on Array, pointers, ASCII value but in any case can't seem to count these characters in a sequence. Ive try a bit of everything. This approach is no good but it the closest i came to it. #include <stdio.h> #include <conio.h> int main() { int charcnt=0,dotcnt=0,commacnt=0,blankcnt=0,i, countA, countB; char str[125]; printf("*****String Manipulations*****\n\n"); printf("Enter a string\n\n"); scanf("%[^'\n']s",str); printf("\n\nEntered String is \" %s \" \n",str); for(i=0;str[i]!='\0';i++) { // COUNTING EXCEPTION CHARS if(str[i]==' ') blankcnt++; if(str[i]=='.') dotcnt++; if(str[i]==',') commacnt++; if (str[i]=='A' || str[i]=='a') countA++; if (str[i]=='B' || str[i]=='b') countA++; } //PRINT RESULT OF COUNT charcnt=i; printf("\n\nTotal Characters : %d",charcnt); printf("\nTotal Blanks : %d",blankcnt); printf("\nTotal Full stops : %d",dotcnt); printf("\nTotal Commas : %d\n\n",commacnt); printf("A%d\n", countA); }

• Sending arbitrarily long string over Java TCP socket

  - by bibismcbryde

  I have an Android app that communicates over a TCP socket with a server I wrote. The method I'm using now to read and write output works fine for smaller strings (up to 60kB) but I get an exception thrown when the string is much longer than that. Here is the relevant part of what I have for the server and client: Server: DataInputStream dis = null; DataOutputStream dos = null; try { dis = new DataInputStream(server.getInputStream()); dos = new DataOutputStream(server.getOutputStream()); String input = ""; input = dis.readUTF(); handle_input info = new handle_input(input, id); String xml = info.handle(); dos.writeUTF(xml); server.close(); } Client: Socket socket = null; DataOutputStream dos = null; DataInputStream dis = null; Boolean result; try { socket = new Socket(ip, port); dos = new DataOutputStream(socket.getOutputStream()); dis = new DataInputStream(socket.getInputStream()); dos.writeUTF(the_text); String in = ""; while (in.equals("")) { in += dis.readUTF(); } } How can I modify it to deal with potentially enormous Strings? I've been looking around and can't seem to find a clear answer. Thanks.

• How can I get 100% test coverage in a Perl module that uses DBI?

  - by BrianH

  I am a bit new to the Devel::Cover module, but have found it very useful in making sure I am not missing tests. A problem I am running into is understanding the report from Devel::Cover. I've looked at the documentation, but can't figure out what I need to test to get 100% coverage. Here is the output from the cover report: line err stmt bran cond sub pod time code ... 36 sub connect_database { 37 3 3 1 1126 my $self = shift; 38 3 100 24 if ( !$self->{dsn} ) { 39 1 7 croak 'dsn not supplied - cannot connect'; 40 } 41 *** 2 33 21 $self->{dbh} = DBI->connect( $self->{dsn}, q{}, q{} ) 42 || croak "$DBI::errstr"; 43 1 11 return $self; 44 } ... line err % l !l&&r !l&&!r expr ----- --- ------ ------ ------ ------ ---- 41 *** 33 1 0 0 'DBI'->connect($$self{'dsn'}, '', '') || croak("$DBI::errstr") And here is and example of my code that tests this specific line: my $database = MyModule::Database->new( { dsn => 'Invalid DSN' }); throws_ok( sub { $database->connect_database() }, qr/Can't connect to data source/, 'Test connection exception (invalid dsn)' ); This test passes - the connect does throw an error and fulfills my "throws_ok" test. I do have some tests that test for a successful connection, which is why I think I have 33% coverage, but if I'm reading it correctly, cover thinks I am not testing the "|| croak" part of the statement. I thought I was, with the "throws_ok" test, but obviously I am missing something. Does anyone have advice on how I can test my DBI-connect line successfully? Thanks!

  i created a c# windows login form and i am saving username or password to a text file but every time i use same username or password that i have saved before it takes new place in that text file. But What i want is to replace the same username or password that is already saved in that text file. this is my code: private void button1_Click(object sender, EventArgs e) { try { FileStream fs = new FileStream("data.txt", FileMode.Append, FileAccess.Write); StreamWriter sw = new StreamWriter(fs); sw.Write("Email ID: "); sw.WriteLine(textBox1.Text); sw.Write("Password: "); sw.Write(textBox2.Text); sw.WriteLine(); sw.WriteLine(); sw.Flush(); sw.Close(); fs.Close(); } catch (Exception) { MessageBox.Show("Error", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); this.Close(); } MessageBox.Show("DONE", "Done", MessageBoxButtons.OK, MessageBoxIcon.Information); textBox1.Clear(); textBox2.Clear(); }

• MVC 3 beta + Dependency Resolver + Unity = got problem

  - by drsim

  Hi everyone. I'm tried to use Dependency Resolver with Unity, and got some problem when my Controller creating. Here example of controller: public class AccountController : Controller { private readonly ICourseService _courseService; public AccountController(ICourseService courseService) { _courseService = courseService; } } But, when Controller try to create - i got an exception "No parameterless constructor defined for this object." I even try to add default constructor for this controller, but courseService didn't create. Also try to add property with [Dependency] attribute - nothing happened. Here is Dependency Resolver class: public class UnityDependencyResolver : IDependencyResolver { private readonly IUnityContainer _container; public UnityDependencyResolver(IUnityContainer container) { _container = container; } public object GetService(Type serviceType) { return _container.IsRegistered(serviceType) ? _container.Resolve(serviceType) : null; } public IEnumerable<object> GetServices(Type serviceType) { return _container.IsRegistered(serviceType) ? _container.ResolveAll(serviceType) : new List<object>(); } } and Global.asax.cs: protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); var container = new UnityContainer(); container.RegisterType<ICourseService, CourseService>(); DependencyResolver.SetResolver(new UnityDependencyResolver(container)); } Can anyone help me ?

• In C# should I reuse a function / property parameter to compute cleaner temporary value or create a

  - by Hamish Grubijan

  The example below may not be problematic as is, but it should be enough to illustrate a point. Imagine that there is a lot more work than trimming going on. public string Thingy { set { // I guess we can throw a null reference exception here on null. value = value.Trim(); // Well, imagine that there is so much processing to do this.thingy = value; // That this.thingy = value.Trim() would not fit on one line ... So, if the assignment has to take two lines, then I either have to abusereuse the parameter, or create a temporary variable. I am not a big fan of temporary variables. On the other hand, I am not a fan of convoluted code. I did not include an example where a function is involved, but I am sure you can imagine it. One concern I have is if a function accepted a string and the parameter was "abused", and then someone changed the signature to ref in both places - this ought to mess things up, but ... who would knowingly make such a change if it already worked without a ref? Seems like it is their responsibility in this case. If I mess with the value of value, am I doing something non-trivial under the hood? If you think that both approaches are acceptable, then which do you prefer and why? Thanks.

• How to handle exceptions from an image-generating Servlet?

  - by ssahmed555

  I have a simple (Servlet, JSP, and JSTL) web app whose main functionality is displaying images retrieved from a back-end server. The controller servlet forwards the user to a JSP that in turn uses another Servlet to display the resulting image on that same JSP. Further down, the JSP has a line similar to: <a href="<c:out value='${imageURL}'/>"><img src="<c:out value='${imageURL}'/>" alt="image view" border="1"></a> which invokes a GET request on the image-generating servlet causing it to generate the image. My question is: how do I handle Exceptions thrown by this image-generating servlet? I already have an error page defined (in web.xml) to handle ServletException within my web app but this doesn't work for this image-generating Servlet, and results in the following errors showing up in my Tomcat server logs: SEVERE: Exception Processing ErrorPage[exceptionType=javax.servlet.ServletException, location=/WEB-INF/ExceptionPage.jsp] java.lang.IllegalStateException: Cannot reset buffer after response has been committed What's my recourse in this situation? I'd like to be able to handle Exceptions thrown from this image-generating Servlet, and display some error on the main UI or forward the user to another error page.

• Force calling the derived class implementation within a generic function in C#?

  - by Adam Hardy

  Ok so I'm currently working with a set of classes that I don't have control over in some pretty generic functions using these objects. Instead of writing literally tens of functions that essentially do the same thing for each class I decided to use a generic function instead. Now the classes I'm dealing with are a little weird in that the derived classes share many of the same properties but the base class that they are derived from doesn't. One such property example is .Parent which exists on a huge number of derived classes but not on the base class and it is this property that I need to use. For ease of understanding I've created a small example as follows: class StandardBaseClass {} // These are simulating the SMO objects class StandardDerivedClass : StandardBaseClass { public object Parent { get; set; } } static class Extensions { public static object GetParent(this StandardDerivedClass sdc) { return sdc.Parent; } public static object GetParent(this StandardBaseClass sbc) { throw new NotImplementedException("StandardBaseClass does not contain a property Parent"); } // This is the Generic function I'm trying to write and need the Parent property. public static void DoSomething<T>(T foo) where T : StandardBaseClass { object Parent = ((T)foo).GetParent(); } } In the above example calling DoSomething() will throw the NotImplemented Exception in the base class's implementation of GetParent(), even though I'm forcing the cast to T which is a StandardDerivedClass. This is contrary to other casting behaviour where by downcasting will force the use of the base class's implementation. I see this behaviour as a bug. Has anyone else out there encountered this?

• C# WPF Unable to control Textboxes

  - by Bo0m3r

  I'm a beginner in coding into C#. While I'm launching a process I can't controls my textboxes. I found some answers on this forum but the explaination is a bit to difficult for me to implement it for my problem. I created a small program that will run a batch file to make a backup. While the backup is running I can't modify my textboxes, disabling buttons etc... I already saw that this is normal but I don't know how to implement the solutions. My last attempt was with Dispatcher.invoke as you can see below. public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); tb_Status.Text = "Ready"; } public void status() { Dispatcher.Invoke(DispatcherPriority.Send, new Action( () => { tb_Status.Text = "The backup is running!"; } ) ); } public void process() { try { Process p = new Process(); p.StartInfo.WindowStyle = ProcessWindowStyle.Minimized; p.StartInfo.CreateNoWindow = true; p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "Robocopy.bat"; p.Start(); string output = p.StandardOutput.ReadToEnd(); p.WaitForExit(); tb_Output.Text = File.ReadAllText("Backup\\log.txt"); } catch (Exception ex) { tb_Status.Text = ex.Message.ToString(); } } private void Bt_Start_Click(object sender, EventArgs e) { status(); Directory.CreateDirectory("Backup"); process(); tb_Status.Text = "The backup finished"; File.Delete("Backup\\log.txt"); } } } Any help is appreciated!

• PHP rewrite an included file - is this a valid script?

  - by Poni

  Hi all! I've made this question: http://stackoverflow.com/questions/2921469/php-mutual-exclusion-mutex As said there, I want several sources to send their stats once in a while, and these stats will be showed at the website's main page. My problem is that I want this to be done in an atomic manner, so no update of the stats will overlap another one running in the background. Now, I came up with this solution and I want you PHP experts to judge it. stats.php <?php define("my_counter", 12); ?> index.php <?php include "stats.php"; echo constant("my_counter"); ?> update.php <?php $old_error_reporting = error_reporting(0); include "stats.php"; define("my_stats_template",' <?php define("my_counter", %d); ?> '); $fd = fopen("stats.php", "w+"); if($fd) { if (flock($fd, LOCK_EX)) { $my_counter = 0; try { $my_counter = constant("my_counter"); } catch(Exception $e) { } $my_counter++; $new_stats = sprintf(constant("my_stats_template"), $my_counter); echo "Counter should stand at $my_counter"; fwrite($fd, $new_stats); } flock($fd, LOCK_UN); fclose($fd); } error_reporting($old_error_reporting); ?> Several clients will call the "update.php" file once every 60sec each. The "index.php" is going to use the "stats.php" file all the time as you can see. What's your opinion?

• Why is the 'var' keyword bad? Or am I just old school?

  - by WaggingSiberian

  Recently I overheard junior developer ask "why do you use 'var' so much?". The mid-level developer responded "I use VAR all the time. I love it! I don't have to figure out the type." I didn't have the time or energy to get into a religious war and hey, I'm still the new guy here :-) I understand var has its place. LINQ comes to mind. But I have also always been told the use of var represents lazy programming and I should just use the correct type to begin with. If it's an int, define it as an int, not a var. When reviewing code, seeing the type makes it easier to follow. My opinion is, it's just lazy but there are exception. Var also reminds me of the VB/VBA variant type. It also had its place. I recall (from many years ago) its usage being less-than-desirable type and it was rather resource hungry. Am I just being stuck in my ways? Should we start using var all the time as my co-worker does?

• How do I make this Java code operate properly? [Multi-threaded, race condition]

  - by Fixee

  I got this code from a student, and it does not work properly because of a race condition involving x++ and x--. He added synchronized to the run() method trying to get rid of this bug, but obviously this only excludes threads from entering run() on the same object (which was never a problem in the first place) but doesn't prevent independent objects from updating the same static variable x at the same time. public class DataRace implements Runnable { static volatile int x; public synchronized void run() { for (int i = 0; i < 10000; i++) { x++; x--; } } public static void main(String[] args) throws Exception { Thread [] threads = new Thread[100]; for (int i = 0; i < threads.length; i++) threads[i] = new Thread(new DataRace()); for (int i = 0; i < threads.length; i++) threads[i].start(); for (int i = 0; i < threads.length; i++) threads[i].join(); System.out.println(x); // x not always 0! } } Since we cannot synchronize on x (because it is primitive), the best solution I can think of is to create a new static object like static String lock = ""; and enclose the x++ and x-- within a synchronized block, locking on lock. But this seems really awkward. Is there a better way?

• Split user.config into different files for faster saving (at runtime)

  - by HorstWalter

  In my c# Windows Forms application (.net 3.5 / VS 2008) I have 3 settings files resulting in one user.config file. One setting file consists of larger data, but is rarely changed. The frequently changed data are very few. However, since the saving of the settings is always writing the whole (XML) file it is always "slow". SettingsSmall.Default.Save(); // slow, even if SettingsSmall consists of little data Could I configure the settings somehow to result in two files, resulting in: SettingsSmall.Default.Save(); // should be fast SettingsBig.Default.Save(); // could be slow, is seldom saved I have seen that I can use the SecionInformation class for further customizing, however what would be the easiest approach for me? Is this possible by just changing the app.config (config.sections)? --- added information about App.config The reason why I get one file might be the configSections in the App.config. This is how it looks: <configSections <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" <section name="XY.A.Properties.Settings2Class" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" / <section name="XY.A.Properties.Settings3Class" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false" / </sectionGroup </configSections I got the sections when I've added the 2nd and 3rd settings file. I have not paid any attention to this, so it was somehow the default of VS 2008. The single user.config has these 3 sections, it is absolutely transparent. Only I do not know how to tell the App.config to create three independent files instead of one. I have "played around" with the app.config above, but e.g. when I remove the config sections my applications terminates with an exception.

• File being used by another process. Reason, and solution?

  - by pstar

  The process cannot access the file 'abc.log' because it is being used by another process. Hi, I've seen this exception from my application occationaly but I am still trying to fix that, hope I will get some insight from stackoverflow. In my application I've have defined a WriteToLog function which will write to a log file. Also the mainForm of my application will launch a backgroundWorker do some job which also calls the WriteToLog. Maybe two threads access a file will cause a problem? But in my code I 've already do my best to write flush and close the text file (I think), and here is my code from WriteToLog: StreamWriter sw = null; string newText = ""; try { //populate the content for newText sw = File.AppendText(LOG_FILE); sw.Write(newText); sw.Flush(); sw.Close(); } catch (IOException ex) { MessageBox.Show("Failed to write to log!\n\t" + ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } finally { if (sw != null) { sw.Close(); } } I think as long as I flush and close the streamWriter, I should be able call the WriteToLog multi-times and in multi-threads isn't it? Or if I am wrong, could I simple make the file open shared, or there are other reason/solutions?

Started booking"); MakeRealBooking(booking, DC.MailRuAgencies.First(a => a.Id == MvcApplication.DefaultMailRuAgencyId)); Log.TraceInformation("Finished booking"); } catch(Exception ex) { Log.TraceEvent(TraceEventType.Error, 0, "Error while booking: {0}", ex.ToString()); } What are you working on right now?

• Connector/C++ compile error

  - by rizzo0917

  When I compile code that includes Connector/C++ headers, I get the following errors: c:\qt\2010.03\mingw\bin../lib/gcc/mingw32/4.4.0/../../../../include/stdint.h:27: error: 'int8_t' has a previous declaration as 'typedef signed char int8_t' c:\qt\2010.03\mingw\bin../lib/gcc/mingw32/4.4.0/../../../../include/stdint.h:31: error: 'int32_t' has a previous declaration as 'typedef int int32_t' c:\qt\2010.03\mingw\bin../lib/gcc/mingw32/4.4.0/../../../../include/stdint.h:32: error: 'uint32_t' has a previous declaration as 'typedef unsigned int uint32_t' Literally all I do is this: #include <cppconn/driver.h> #include <cppconn/exception.h> #include <cppconn/resultset.h> #include <cppconn/statement.h> #include <cppconn/prepared_statement.h> Now I can go into the file and comment the lines out that give me errors: //typedef signed char int8_t; //typedef int int32_t; //typedef unsigned uint32_t; It compiles, but when I try to run the mysql code: sql::Driver *driver; driver = get_driver_instance(); I get this output test.exe exited with code -1073741515 Any Ideas?

• How do you get the solution directory in C# (VS 2008) in code?

  - by IsaacB

  Hi, Got an annoying problem here. I've got an NHibernate/Forms application I'm working through SVN. I made some of my own controls, but when I drag and drop those (or view some form editors where I have already dragged and dropped) onto some of my other controls, Visual studio decides it needs to execute some of the code I wrote, including the part that looks for hibernate.cfg.xml. I have no idea why this is, but (sometimes!) when it executes the code during my form load or drag and drop it switches the current directory to C:\program files\vs 9.0\common7\ide, and then nhibernate throws an exception that it can't find hibernate.cfg.xml, because I'm searching for that in a relative path. Now, I don't want to hard code the location of hibernate.cfg.xml, or just copy hibernate.cfg.xml to the ide directory (which will work). I want a solution that gets the solutions directory while the current directory is common7\ide. Something that will let someone view my forms in the designer on a fresh checkout to an arbitrary directory on an arbitrary machine. And no, I'm not about to load the controls in code. I have so many controls within controls that it is a nightmare to line everything up without it. I tried a pre build event that made a file that has the solution directory in it, but of course how can I find that from common7\ide? All the projects files need to be in the solution directory because of svn. Thanks for your help guys, I've already spent a few hours fiddling with this in vain.

• sqlobject: No connection has been defined for this thread or process

  - by Claudiu

  I'm using sqlobject in Python. I connect to the database with conn = connectionForURI(connStr) conn.makeConnection() This succeeds, and I can do queries on the connection: g_conn = conn.getConnection() cur = g_conn.cursor() cur.execute(query) res = cur.fetchall() This works as intended. However, I also defined some classes, e.g: class User(SQLObject): class sqlmeta: table = "gui_user" username = StringCol(length=16, alternateID=True) password = StringCol(length=16) balance = FloatCol(default=0) When I try to do a query using the class: User.selectBy(username="foo") I get an exception: ... File "c:\python25\lib\site-packages\SQLObject-0.12.4-py2.5.egg\sqlobject\main.py", line 1371, in selectBy conn = connection or cls._connection File "c:\python25\lib\site-packages\SQLObject-0.12.4-py2.5.egg\sqlobject\dbconnection.py", line 837, in __get__ return self.getConnection() File "c:\python25\lib\site-packages\SQLObject-0.12.4-py2.5.egg\sqlobject\dbconnection.py", line 850, in getConnection "No connection has been defined for this thread " AttributeError: No connection has been defined for this thread or process How do I define a connection for a thread? I just realized I can pass in a connection keyword which I can give conn to to make it work, but how do I get it to work if I weren't to do that?

• Analyzing BSOD without a dump

  - by eeoo2555

  One of the drivers I'm developing has caused a BSOD. Unfortunately a dump file was not created since it was not configured / low resources. I was trying to reproduce this crash but no luck so far. Is there any way to get some info using WinDbg or any other tool? I have this information: A screenshot of the BSOD The .sys file. Its pdb The source code The machine it was crashed on I have everything except the dump itself. Your help will be much appreciated. As I said above, no dump (/minidump) exists. This is the actual problem. For this specific crash, I know I won't be able to get the stack. Just getting the specific line of code will be good enough. Because the BSOD contains the module's address, it seems like there should be a way to detect which line exactly is it. As I mentioned above, I do have the .sys file, the pdb and the source code. This is the specific code taken from MSDN: SYSTEM_SERVICE_EXCEPTION. How can I know from there what was the specific line? and/or the specific exception raised?

• selective UnknownHostException

  - by Stephan

  Hi everybody! I am getting said Exception in my program, but only in certain cases. First of all, I have the internet permission set:<uses-permission android:name="android.permission.INTERNET" />, and I tried the two method of this and this thread (they don't work in my case). The scenario is the following: I send a GET request to a rest service (e.g. http://my.web.site/request.php?attr=blah) and I do get a correct xml back. Now, in this xml there are some resources described, one of which is an url to an image (e.g http://my.web.site/images/img.jpg). Here it's where it fails! Here I consistently receive a UnknownHostException. I find it weird, since it's the same domain and everything. Accessing the img url from browser works (both from the emulator browser and pc browser). I tried from a device too but it doesn't get the image anyway. Any idea on why this weird behavior? EDIT: all my tests were on emulator and device, but connected to a wifi network. I tried also using the internet connection of my provider on the phone (i.e. bypassing home network), and still the behavior is the same... I found this bug which I assume is the source of this problem, but still no solution (after more than 1.5years). Any ideas?
