  • Associate File Extension with Application

    - by fneep
    I've written a program that edits a specific filetype , and I want to give the user the option to set my application as the default editor for this filetype (since I don't want an installer) on startup. I've tried to write a re-useable method that associates a file for me (preferably on any OS, although I'm running Vista) by adding a key to HKEY_CLASSES_ROOT, and am using it with my application, but it doesn't seem to work. public static void SetAssociation(string Extension, string KeyName, string OpenWith, string FileDescription) { RegistryKey BaseKey; RegistryKey OpenMethod; RegistryKey Shell; RegistryKey CurrentUser; BaseKey = Registry.ClassesRoot.CreateSubKey(Extension); BaseKey.SetValue("", KeyName); OpenMethod = Registry.ClassesRoot.CreateSubKey(KeyName); OpenMethod.SetValue("", FileDescription); OpenMethod.CreateSubKey("DefaultIcon").SetValue("", "\"" + OpenWith + "\",0"); Shell = OpenMethod.CreateSubKey("Shell"); Shell.CreateSubKey("edit").CreateSubKey("command").SetValue("", "\"" + OpenWith + "\"" + " \"%1\""); Shell.CreateSubKey("open").CreateSubKey("command").SetValue("", "\"" + OpenWith + "\"" + " \"%1\""); BaseKey.Close(); OpenMethod.Close(); Shell.Close(); CurrentUser = Registry.CurrentUser.CreateSubKey(@"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ucs"); CurrentUser = CurrentUser.OpenSubKey("UserChoice", RegistryKeyPermissionCheck.ReadWriteSubTree, System.Security.AccessControl.RegistryRights.FullControl); CurrentUser.SetValue("Progid", KeyName, RegistryValueKind.String); CurrentUser.Close(); }

  • NSString writeToFile operation couldn't be completed

    - by Chonch
    Hey, I have an xml file in my application bundle. I want to copy it to the documents folder at installation and then, every time the app launches, get the newest version of this file from the Internet. I use this code: // Check if the file exists in the documents folder NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; if (![[NSFileManager defaultManager] fileExistsAtPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"]]) // If not, copy it there (from the bundle) [[NSFileManager defaultManager] copyItemAtPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"OriginalFile.xml"] toPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] error:nil]; // Get the newest version of the file from the server NSURL *url=[[NSURL alloc] initWithString:@"http://www.sitename.com/webservice.asmx/webserviceName"]; NSString *results = [[NSString alloc] initWithContentsOfURL:url]; // Replace the current version with the newest one, only if it is valid if (results != nil) [results writeToFile:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil]; The problem is that the writeToFile command always returns NO and the file's contents remain identical to the original file I included in my app bundle. I checked the value of results and it's correct. I also made sure that the app does perform the writeToString command, but still, it always returns NO. Can anybody tell me what I'm doing wrong? Thanks,

  • Selecting a whole database over an individual table to output to file

    - by Daniel Wrigley
    :::::::: EDIT :::::::: New code for people to have a look at, one question I have with this is where do I set were the *.gz file is saved? $backupFile = $dbname . date("Y-m-d-H-i-s") . '.gz'; $command = "mysqldump --opt -h $dbhost -u $dbuser -p $dbpass $dbname | gzip > $backupFile"; system($command); Also why the hell can you not reply yo your own post with answering it? :( :::::::: EDIT :::::::: Ok Im having trouble finding out how to select a full database for backup as an *.sql file rather than only an individual table. On the localhost I have several databases with one named "foo" and it is that which I want to backup and not any of the individual tables inside the database "foo". The code to connect to the database; //Database Information $dbhost = "localhost"; $dbname = "foo"; $dbuser = "bar"; $dbpass = "rulz"; //Connect to database mysql_connect ($dbhost, $dbuser, $dbpass) or die("Could not connect: ".mysql_error()); mysql_select_db($dbname) or die(mysql_error()); The code to backup the database; // Grab the time to know when this post was submitted $time = date('Y-m-d-H-i-s'); $tableName = 'foo'; $backupFile = '/sql/backup/'. $time .'.sql'; $query = "SELECT * INTO OUTFILE '". $backupFile ."' FROM ". $tableName .""; $result = mysql_query($query)or die("Database query died: " . mysql_error()); My brain is hurting near to the end of the day so no doubts i've missed something out very obvious. Thanks in advance to anyone helping me out.

  • clearTimeout not working in javascript autocomplete script

    - by Travis
    I am using the following code as part of an autocomplete script to avoid hammering the server with every keystroke: var that = this; textInput.bind("keyup", function() { clearTimeout(that.timer); that.timer = setTimeout (that.doStuff(), 2000); }); Unfortunately, this does not clear the old timers. They still all execute. Does anyone know what I'm missing? Thanks!

  • .NET Speech recognition plugin Runtime Error: Unhandled Exception. What could possibly cause it?

    - by manuel
    I'm writing a plugin (dll file) for speech recognition, and I'm creating a WinForm as its interface/dialog. When I run the plugin and click the 'Speak' to start the initialization, I get an unhandled exception. Here is a piece of the code: public ref class Dialog : public System::Windows::Forms::Form { public: SpeechRecognitionEngine^ sre; private: System::Void btnSpeak_Click(System::Object^ sender, System::EventArgs^ e) { Initialize(); } protected: void Initialize() { if (System::Threading::Thread::CurrentThread->GetApartmentState() != System::Threading::ApartmentState::STA) { throw gcnew InvalidOperationException("UI thread required"); } //create the recognition engine sre = gcnew SpeechRecognitionEngine(); //set our recognition engine to use the default audio device sre->SetInputToDefaultAudioDevice(); //create a new GrammarBuilder to specify which commands we want to use GrammarBuilder^ grammarBuilder = gcnew GrammarBuilder(); //append all the choices we want for commands. //we want to be able to move, stop, quit the game, and check for the cake. grammarBuilder->Append(gcnew Choices("play", "stop")); //create the Grammar from th GrammarBuilder Grammar^ customGrammar = gcnew Grammar(grammarBuilder); //unload any grammars from the recognition engine sre->UnloadAllGrammars(); //load our new Grammar sre->LoadGrammar(customGrammar); //add an event handler so we get events whenever the engine recognizes spoken commands sre->SpeechRecognized += gcnew EventHandler<SpeechRecognizedEventArgs^> (this, &Dialog::sre_SpeechRecognized); //set the recognition engine to keep running after recognizing a command. //if we had used RecognizeMode.Single, the engine would quite listening after //the first recognized command. sre->RecognizeAsync(RecognizeMode::Multiple); //this->init(); } void sre_SpeechRecognized(Object^ sender, SpeechRecognizedEventArgs^ e) { //simple check to see what the result of the recognition was if (e->Result->Text == "play") { MessageBox(plugin.hwndParent, L"play", 0, 0); } if (e->Result->Text == "stop") { MessageBox(plugin.hwndParent, L"stop", 0, 0); } } };

  • Calling function dynamically by using Reflection

    - by Alaa'
    Hi, I'm generating dll files contain code like the following example : // using System; using System.Collections; using System.Xml; using System.IO; using System.Windows.Forms; namespace CSharpScripter { public class TestClass : CSharpScripter.Command { private int i=1; private int j=2; public int k=3; public TestClass6() { } public void display (int i,int j,int k) { string a = null; a= k.ToString(); string a1 = null; a1= this.i.ToString(); string a2 = null; a2= j.ToString(); MessageBox.Show(" working! "+ "k="+ a +" i="+a1 + " j="+ a2); } public void setValues(int i,int j,int k1) { this.i=i; this.j=j; k=k1; } // I'm compiling the pervious code, then I execute an object from the dll file. So, in the second part of the code ( Executing part), I'm just calling the execute function, It contains a call for a function, I named here: display. For that I need to set values in the declaration by a setValue function. I want it to been called dynamically (setValues ), which has declaration like : public void(Parameter[] parameters) { //some code block here } For this situation I used Reflection. // Type objectType = testClass.GetType(); MethodInfo members = objectType.GetMethod("setValues"); ParameterInfo[] parameters = members.GetParameters(); For) int t = 0; t < parameters.Length; t++) { If (parameters[t]. ParameterType == typeof()) { object value = this.textBox2.Text; parameters.SetValue)Convert.ChangeType(value,parameters[t].ParameterType), t); } } // But it throws an casting error" Object cannot be stored in an array of this type." at last line, in first parameter for (setValue) methode. What is the problem here? And How I can call the method Dynamically after the previous code, by( Invoke) or is there a better way? Thanks.

  • Problem changing Java version using alternatives

    - by Brian Lewis
    I'm not quite sure how I got into this mess, but for some reason I'm not able to change the current version of Java using alternatives. I can run alternatives --config java and type my selection but when I echo the version number for either java or javac, it spits back out 1.5 every time (despite alternatives showing the current version is 1.6). The server I'm working with is running RHEL5, by the way. I have verified that the paths used in alternatives are pointing to the correct directories. Here's some output from my session: [brilewis@myserver]$ sudo /usr/sbin/update-alternatives --config java There are 3 programs which provide 'java'. Selection Command ** 1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java + 2 /usr/java/jdk1.5.0_10/bin/java 3 /usr/java/jdk1.6.0_16/bin/java Enter to keep the current selection[+], or type selection number: 3 [brilewis@myserver]$ java -version java version "1.5.0_10" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03) Java HotSpot(TM) Server VM (build 1.5.0_10-b03, mixed mode) [brilewis@myserver]$ sudo /usr/sbin/update-alternatives --config java There are 3 programs which provide 'java'.

  • Using Ruby/Python code in an iPhone OS app?

    - by igul222
    My app needs to use a library which is only available for Python and Ruby. From my understanding, Apple allows Ruby to run on iPhone as long as users can't execute arbitrary code (Rhomobile uses Ruby). How can I bundle Ruby/Python with my app, call a function from my Obj-C code, and get the result (a string) back in C or Obj-C format?

  • TypeScript - separating code output

    - by Andrea Baccega
    i'm trying typescript and I find it very useful. I've a quite large project and i was considering rewriting it using typescript. The main problem here is the following: file A.ts: class A extends B { // A stuff } file B.ts: class B { // B stuff } If I compile A.ts with this command: tsc --out compiledA.js A.ts I'll get error from the compiler cause he doesn't know how to threat the "B" after extends. So, a "solution" would be including in A.ts (as first line of code): /// <reference path="./B.ts" /> Compiling again A.ts with the same command tsc --out compiledA.js A.ts Will result in compiledA.js containing both B.ts and A.ts code. ( which could be very nice ) In my case, I only need to compile the A.ts code in the compiledA.js file and I don't want the B.ts stuff to be in there. Indeed, what I want is: tsc --out A.js A.ts = compile only the A.ts stuff tsc --out B.js B.ts = compile only the B.ts stuff I can do it by removing the "extends" keyword but doing that I'll loose most of the typescript goodness. Can someone telll me if there's a way to do this ?

  • An Interactive Console I/O Wrapper/Interceptor in C# - What is the issue?

    - by amazedsaint
    I was trying to put together an interactive Console interceptor/wrapper in C# over the weekend, by re-mixing few code samples I've found in SO and other sites. With what I've as of now, I'm unable to read back from the console reliably. Any quick pointers? public class ConsoleInterceptor { Process _interProc; public event Action<string> OutputReceivedEvent; public ConsoleInterceptor() { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo("cmd"); InitializeInterpreter(); } public ConsoleInterceptor(string command) { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo(command); InitializeInterpreter(); } public Process InterProc { get { return _interProc; } } private void InitializeInterpreter() { InterProc.StartInfo.RedirectStandardInput = true; InterProc.StartInfo.RedirectStandardOutput = true; InterProc.StartInfo.RedirectStandardError = true; InterProc.StartInfo.CreateNoWindow = true; InterProc.StartInfo.UseShellExecute = false; InterProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; bool started = InterProc.Start(); Redirect(InterProc.StandardOutput); Redirect(InterProc.StandardError); } private void Redirect(StreamReader input) { new Thread((a) => { var buffer = new char[1]; while (true) { if (input.Read(buffer, 0, 1) > 0) OutputReceived(new string(buffer)); }; }).Start(); } private void OutputReceived(string text) { if (OutputReceivedEvent != null) OutputReceivedEvent(text); } public void Input(string input) { InterProc.StandardInput.WriteLine(input); InterProc.StandardInput.Flush(); } }

  • Best practise for overriding static classes

    - by maxp
    As it is not possible to override a static class in c#, if i want to override a method I generally define a delegate matching the signature of the static method, then modify the method along the lines of: public static void foo(int bar) { if (delegatename!=null) { delegatename.Invoke(bar); } else { //execute previous code as normal } } I feel a twinge of guilt, knowing this is a bit messy. Can anyone suggest a neater solution to this problem (other than rewriting the original structure)

  • Question about DBD::CSB Statement-Functions

    - by sid_com
    From the SQL::Statement::Functions documentation: Function syntax When using SQL::Statement/SQL::Parser directly to parse SQL, functions (either built-in or user-defined) may occur anywhere in a SQL statement that values, column names, table names, or predicates may occur. When using the modules through a DBD or in any other context in which the SQL is both parsed and executed, functions can occur in the same places except that they can not occur in the column selection clause of a SELECT statement that contains a FROM clause. # valid for both parsing and executing SELECT MyFunc(args); SELECT * FROM MyFunc(args); SELECT * FROM x WHERE MyFuncs(args); SELECT * FROM x WHERE y < MyFuncs(args); # valid only for parsing (won't work from a DBD) SELECT MyFunc(args) FROM x WHERE y; Reading this I would expect that the first SELECT-statement of my example shouldn't work and the second should but it is quite the contrary. #!/usr/bin/env perl use warnings; use strict; use 5.010; use DBI; open my $fh, '>', 'test.csv' or die $!; say $fh "id,name"; say $fh "1,Brown"; say $fh "2,Smith"; say $fh "7,Smith"; say $fh "8,Green"; close $fh; my $dbh = DBI->connect ( 'dbi:CSV:', undef, undef, { RaiseError => 1, f_ext => '.csv', }); my $table = 'test'; say "\nSELECT 1"; my $sth = $dbh->prepare ( "SELECT MAX( id ) FROM $table WHERE name LIKE 'Smith'" ); $sth->execute (); $sth->dump_results(); say "\nSELECT 2"; $sth = $dbh->prepare ( "SELECT * FROM $table WHERE id = MAX( id )" ); $sth->execute (); $sth->dump_results(); outputs: SELECT 1 '7' 1 rows SELECT 2 Unknown function 'MAX' at /usr/lib/perl5/site_perl/5.10.0/SQL/Parser.pm line 2893.

  • BeginInvoke on ObservableCollection not immediate.

    - by Padu Merloti
    In my code I subscribe to an event that happens on a different thread. Every time this event happens, I receive an string that is posted to the observable collection: Dispatcher currentDispatcher = Dispatcher.CurrentDispatcher; var SerialLog = new ObservableCollection<string>(); private void hitStation_RawCommandSent(object sender, StringEventArgs e) { string command = e.Value.Replace("\r\n", ""); Action dispatchAction = () => SerialLog.Add(command); currentDispatcher.BeginInvoke(dispatchAction, DispatcherPriority.Render); } The code below is in my view model (could be in the code behind, it doesn't matter in this case). When I call "hitstation.PrepareHit", the event above gets called a couple times, then I wait and call "hitStation.HitBall", and the event above gets called a couple more times. private void HitBall() { try { try { Mouse.OverrideCursor = Cursors.Wait; //prepare hit hitStation.PrepareHit(hitSpeed); Thread.Wait(1000); PlayWarning(); //hit hitStation.HitBall(hitSpeed); } catch (TimeoutException ex) { MessageBox.Show("Timeout hitting ball: " + ex.Message); } } finally { Mouse.OverrideCursor = null; } } The problem I'm having is that the ListBox that is bound to my SerialLog gets updated only when the HitBall method finishes. I was expecting seeing a bunch of updates from the PrepareHit, a pause and then a bunch more updates from the HitBall. I've tried a couple of DispatcherPriority arguments, but they don't seem to have any effect.

  • Maven: properties not being substituted

    I'm using a maven plugin for install4j in my project, located here. That plugin lets you pass variables to install4j using the <compilerVariables> section. Here's the relevant section of my pom: <plugin> <groupId>com.google.code.maven-install4j</groupId> <artifactId>maven-install4j-plugin</artifactId> <version>0.1.1</version> <configuration> <executable>${devenv.install4jc}</executable> <configFile>${basedir}/newinstaller/ehd.install4j</configFile> <releaseId>${project.version}</releaseId> <attach>false</attach> <skipOnMissingExecutable>false</skipOnMissingExecutable> <compilerVariables> <property> <name>m2_home</name> <value>${settings.localRepository}</value> </property> </compilerVariables> </configuration> </plugin> The problem is that ${settings.localRepository} is not being substituted with the actual directory when I run the plugin. Here's the command line script that install4j is generating: [INFO] Running the following command for install4j compile: /bin/sh -c /home/zach/install4j/bin/install4jc --release=9.1-SNAPSHOT --destination="/home/zach/projects/java/ehdtrunk/target/install4j" -D m2_home=${settings.localRepository} /home/zach/projects/java/ehdtrunk/newinstaller/ehd.install4j Is this the fault of the plugin?

    Hi everybody, I develop a simple file manager inside an ASP.NET Web site (not web application). I notice that every time I rename or delete a folder, the site gets recompiled - i.e. the very next web request after delete or rename operation takes considerably much time to execute. It's only true for folders, not for files. Why does this occur? P.S. I use WebDev server (Cassini), haven't tested in on IIS yet.
