  • How do i cast an object to a string when object is not a string?

    - by acidzombie24
    I have class A, B, C. They all can implicitly convert to a string public static implicit operator A(string sz_) { ... return sz; } I have code that does this object AClassWhichImplicitlyConvertsToString { ... ((KnownType)(String)AClassWhichImplicitlyConvertsToString).KnownFunc() } The problem is, AClassWhichImplicitlyConvertsToString isnt a string even though it can be typecast into one implicitly. I get a bad cast exception. How do i say its ok as long as the class has an operator to convert into a string?

    - by Bggreen
    I am attempting to convert Java code to Jython and am using the apache Log and LogFactory imports. I am attempting to emulate Foo.class in Jython The chunk of code is as follows: in Java import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; public class MyClass { private static final Log log = LogFactory.getLog(MyClass.class); public MyClass(Document dom) { //code } How can I emulate this same behavior of MyClass.class in Jython/Python?

  • What is the best approach to use different CFLAGS for the same source files?

    - by evilsocket
    Hello, i need to build the same source tree twice, 1 - with normal cflags to build the project binary 2 - with cflags plus -fPIC to build a static library that would be some sort of SDK to develop project dynamic modules. Using only one Makefile, what is the best approach to accomplish this? It would be nice to do some sort of : all: $(OBJECTS) lib_rule: $(OBJECTS) CFLAGS += -fPIC .cpp.o: $(CC) -c $< -o $@ $(CFLAGS) But obviously it can't be done. Thanks

  • How to assign WPF resources to other resource tags

    - by Tom
    This is quite obscure, I may just be missing something extremely simple. Scenario 1 Lets say I create a gradient brush, like this in my <Window.Resources> section: <LinearGradientBrush x:Key="GridRowSelectedBackBrushGradient" StartPoint="0,0" EndPoint="0,1"> <GradientStop Color="#404040" Offset="0.0" /> <GradientStop Color="#404040" Offset="0.5" /> <GradientStop Color="#000000" Offset="0.6" /> <GradientStop Color="#000000" Offset="1.0" /> </LinearGradientBrush> Then much later on, I want to override the HighlightBrushKey for a DataGrid. I have basically done it like this (horrible); <LinearGradientBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" GradientStops="{Binding Source={StaticResource GridRowSelectedBackBrushGradient}, Path=GradientStops}" StartPoint="{Binding Source={StaticResource GridRowSelectedBackBrushGradient}, Path=StartPoint}" EndPoint="{Binding Source={StaticResource GridRowSelectedBackBrushGradient}, Path=EndPoint}" /> This is obviously not the most slick way of referencing a resource. I also came up with the following problem, which is almost identical. Scenario 2 Say I created two colors in my <Window.Resources> markup, like so: <SolidColorBrush x:Key="DataGridRowBackgroundBrush" Color="#EAF2FB" /> <SolidColorBrush x:Key="DataGridRowBackgroundAltBrush" Color="#FFFFFF" /> Then later on, I want to supply them in an Array, which feeds the ConverterParameter on a Binding so I can supply the custom Converter with my static resource instances: <Setter Property="Background"> <Setter.Value> <Binding RelativeSource="{RelativeSource Mode=Self}" Converter="{StaticResource BackgroundBrushConverter}"> <Binding.ConverterParameter> <x:Array Type="{x:Type Brush}"> <SolidColorBrush Color="{Binding Source={StaticResource DataGridRowBackgroundBrush}, Path=Color}" /> <SolidColorBrush Color="{Binding Source={StaticResource DataGridRowBackgroundAltBrush}, Path=Color}" /> </x:Array> </Binding.ConverterParameter> </Binding> </Setter.Value> </Setter> What I've done is attempt to rereference an existing resource, but in my efforts I've actually recreated the resource, and bound the properties so they match. Again, this is not ideal. Because I've now hit this problem at least twice, is there a better way? Thanks, Tom

  • A question about making a C# class persistent during a file load

    - by Adam
    Apologies for the indescriptive title, however it's the best I could think of for the moment. Basically, I've written a singleton class that loads files into a database. These files are typically large, and take hours to process. What I am looking for is to make a method where I can have this class running, and be able to call methods from within it, even if it's calling class is shut down. The singleton class is simple. It starts a thread that loads the file into the database, while having methods to report on the current status. In a nutshell it's al little like this: public sealed class BulkFileLoader { static BulkFileLoader instance = null; int currentCount = 0; BulkFileLoader() public static BulkFileLoader Instance { // Instanciate the instance class if necessary, and return it } public void Go() { // kick of 'ProcessFile' thread } public void GetCurrentCount() { return currentCount; } private void ProcessFile() { while (more rows in the import file) { // insert the row into the database currentCount++; } } } The idea is that you can get an instance of BulkFileLoader to execute, which will process a file to load, while at any time you can get realtime updates on the number of rows its done so far using the GetCurrentCount() method. This works fine, except the calling class needs to stay open the whole time for the processing to continue. As soon as I stop the calling class, the BulkFileLoader instance is removed, and it stops processing the file. What I am after is a solution where it will continue to run independently, regardless of what happens to the calling class. I then tried another approach. I created a simple console application that kicks off the BulkFileLoader, and then wrapped it around as a process. This fixes one problem, since now when I kick off the process, the file will continue to load even if I close the class that called the process. However, now the problem I have is that cannot get updates on the current count, since if I try and get the instance of BulkFileLoader (which, as mentioned before is a singleton), it creates a new instance, rather than returning the instance that is currently in the executing process. It would appear that singletons don't extend into the scope of other processes running on the machine. In the end, I want to be able to kick off the BulkFileLoader, and at any time be able to find out how many rows it's processed. However, that is even if I close the application I used to start it. Can anyone see a solution to my problem?

  • How do I get the current Cmdlet from another object?

    - by John Vottero
    What's the best way to get the current PowerShell Cmdlet from another object? If I create a helper object that is not a Cmdlet but will be called by Cmdlets, the helper methods may want to call WriteVerbose, WriteDebug etc. What's the best way to get access to that? Is there a static PowerShell method that will return the current Cmdlet or do I need to have the Cmdlet pass itself to the helper?

  • Multipage forms for joomla (looking outside the box)

    - by John Snow
    I have created a number of forms using various Joomla components which have more or less worked successfully. Recently I have attempted to create mult-page forms - the forms work...but they are slow as molasses. Having spent a couple of weeks trying to resolve this and not seeing any signs of improvement ...... I wonder if anyone has experience of using hosted forms services in Joomla either using a wrapper or as a static page within a Joomla site. Any pointers or recommendations would be appreciated.

    I have a Flash object that loads fine in a static sample HTML but doesnt inside the application. I saw something interesting in firebug. When the page loads the object is loaded two times. In the first one I get a Partial Response status but the content-type of the package is right. In the second time the whole package is transfered but the content-type is wrong! I am using apache 2.2.14.

  • Good ways to map a 2D side shooter (somewhat like liero, or soldat)

    - by Blaze
    I'm wondering what way would be best to render a 2D map for a shooter (these will be static maps) similar to Soldat. Multiple options I've considered are a tile based map (stored in txt files), or just creating different classes for the different terrains I plan to use and creating a data structure to read/store them in a file. (I want to also be able to include things like jumping/running on walls, sliding down walls/slopes ect) I feel like there must be a better way than either of these, but haven't been able to find definitive information :/ Thanks :)

  • Why sockets does not die when server dies? Why socket dies when server is alive?

    - by Roman
    I try to play with sockets a bit. For that I wrote very simple "client" and "server" applications. Client: import java.net.*; public class client { public static void main(String[] args) throws Exception { InetAddress localhost = InetAddress.getLocalHost(); System.out.println("before"); Socket clientSideSocket = null; try { clientSideSocket = new Socket(localhost,12345,localhost,54321); } catch (ConnectException e) { System.out.println("Connection Refused"); } System.out.println("after"); if (clientSideSocket != null) { clientSideSocket.close(); } } } Server: import java.net.*; public class server { public static void main(String[] args) throws Exception { ServerSocket listener = new ServerSocket(12345); while (true) { Socket serverSideSocket = listener.accept(); System.out.println("A client-request is accepted."); } } } And I found a behavior that I cannot explain: I start a server, than I start a client. Connection is successfully established (client stops running and server is running). Then I close the server and start it again in a second. After that I start a client and it writes "Connection Refused". It seems to me that the server "remember" the old connection and does not want to open the second connection twice. But I do not understand how it is possible. Because I killed the previous server and started a new one! I do not start the server immediately after the previous one was killed (I wait like 20 seconds). In this case the server "forget" the socket from the previous server and accepts the request from the client. I start the server and then I start the client. Connection is established (server writes: "A client-request is accepted"). Then I wait a minute and start the client again. And server (which was running the whole time) accept the request again! Why? The server should not accept the request from the same client-IP and client-port but it does!

  • Android App Crashes On Second Run

    - by user1091286
    My app runs fine on first run. On the Menu I added two choices options and quit. options which set up a new intent who goes to a PreferenceActivity and quit which simply call: "android.os.Process.killProcess(android.os.Process.myPid());" On the second time I run my app (after I quit from inside the emulator) it crashes.. Ideas? the menu is called by the foolowing code: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu , menu); return true; } - @Override public boolean onOptionsItemSelected(MenuItem item) { // Set up a new intent between the updater service and the main screen Intent options = new Intent(this, OptionsScreenActivity.class);

  • JComobox is not showing in the JDialog

    - by Pujan Srivastava
    I have 2 classes. when I put bold 3 lines in the method addCourses() the dialog does not show combobox in the Panel but when I remove from addCourses and put those bold lines in the constructor, JComboBox are shown in the Panel. But data will not show because data items updates to ComboBox will happen after Constructor is created. How can I solve this problem. this.mainPanel.add(courseCombo, BorderLayout.NORTH); this.mainPanel.add(sessionCombo, BorderLayout.CENTER); this.mainPanel.add(courseButton, BorderLayout.SOUTH); public class Updator { CourseListFrame clf = new CourseListFrame(); for(...){ clf.addContentsToBox(displayName, className); } clf.addCourses(); } and second class is public class CourseListFrame extends JDialog implements ActionListener { public JPanel mainPanel = new JPanel(new BorderLayout(2, 2)); public JButton courseButton = new JButton(("Submit")); public JComboBox courseCombo; public JComboBox sessionCombo; public Multimap<String, String> map; // = HashMultimap.create(); public static CourseListFrame courseListDialog; public CourseListFrame() { super(this.getMainFrame()); this.getContentPane().add(mainPanel); map = HashMultimap.create(); courseCombo = new JComboBox(); courseCombo.addItem("Select Courses"); courseCombo.addActionListener(this); sessionCombo = new JComboBox(); } public void addContentsToBox(String course, String session) { map.put(course, session); courseCombo.addItem(course); } public void actionPerformed(ActionEvent e) { JComboBox cb = (JComboBox) e.getSource(); String str = (String) cb.getSelectedItem(); setSessionCombo(str); } public void setSessionCombo(String course) { if (map.containsKey(course)) { sessionCombo.removeAllItems(); Iterator it = map.get(course).iterator(); while (it.hasNext()) { sessionCombo.addItem(it.next()); } } } public void addCourses() { this.mainPanel.add(courseCombo, BorderLayout.NORTH); this.mainPanel.add(sessionCombo, BorderLayout.CENTER); this.mainPanel.add(courseButton, BorderLayout.SOUTH); } public static void showCourseListDialog() { if (courseListDialog == null) { courseListDialog = new CourseListFrame(); } courseListDialog.pack(); courseListDialog.setVisible(true); courseListDialog.setSize(260, 180); } }
