  • Cocoa: Hide one application

    - by Craig
    Is it possible to hide one specific application using cocoa? I know you can hide all other applications using the following code [[NSWorkspace sharedWorkspace] performSelectorOnMainThread:@selector(hideOtherApplications) withObject:NULL waitUntilDone:NO]; But is it possible to hide just one specific application say Safari for example?

  • Structs, strtok, segmentation fault

    - by FILIaS
    I'm trying to make a programme with structs and files.The following is just a part of my code(it;s not all). What i'm trying to do is: ask the user to write his command. eg. delete John eg. enter John James 5000 ipad purchase. The problem is that I want to split the command in order to save its 'args' for a struct element. That's why i used strtok. BUT I'm facing another problem in who to 'put' these on the struct. #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX 100 char command[1500]; struct catalogue { char short_name[50]; char surname[50]; signed int amount; char description[1000]; }*catalog[MAX]; int main ( int argc, char *argv[] ) { int i,n; char choice[3]; printf(">sort1: Print savings sorted by surname\n"); printf(">sort2: Print savings sorted by amount\n"); printf(">search+name:Print savings of each name searched\n"); printf(">delete+full_name+amount: Erase saving\n"); printf(">enter+full_name+amount+description: Enter saving \n"); printf(">quit: Update + EXIT program.\n"); printf("Choose your selection:\n>"); gets(command); //it save the whole command /*in choice it;s saved only the first 2 letters(needed for menu choice again)*/ strncpy(choice,command,2); choice[2]='\0'; char** args = (char**)malloc(strlen(command)*sizeof(char*)); memset(args, 0, sizeof(char*)*strlen(command)); char* curToken = strtok(command, " \t"); for (n = 0; curToken != NULL; ++n) { args[n] = strdup(curToken); curToken = strtok(NULL, " \t"); *catalog[n]->short_name=*args[1]; *catalog[n]->surname=args[2]; catalog[n]->amount=atoi(args[3]); *catalog[n]->description=args[4]; } return 0; } I get a warning (warning: assignment makes integer from pointer without a cast) for the lines: *catalog[n]->short_name=*args[1]; *catalog[n]->surname=args[2]; *catalog[n]->description=args[4]; As a result, after running the program i get a Segmentation Fault... Any help? Any ideas?

  • Android: handle unexpected internet disconnect while downloading data

    - by M.A. Cape
    Hi, I have here a function that downloads data from a remote server to file. I am still not confident with my code. My question is, what if while reading the stream and saving the data to a file and suddenly I was disconnected in the internet, will these catch exceptions below can really catch that kind of incident? If not, can you suggest how to handle this kind of incident? Note: I call this function in a thread so that the UI won't be blocked. public static boolean getFromRemote(String link, String fileName, Context context){ boolean dataReceived = false; ConnectivityManager connec = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE); if (connec.getNetworkInfo(0).isConnected() || connec.getNetworkInfo(1).isConnected()){ try { HttpClient httpClient = new DefaultHttpClient(); HttpGet httpGet = new HttpGet(link); HttpParams params = httpClient.getParams(); HttpConnectionParams.setConnectionTimeout(params, 30000); HttpConnectionParams.setSoTimeout(params, 30000); HttpResponse response; response = httpClient.execute(httpGet); int statusCode = response.getStatusLine().getStatusCode(); if (statusCode == 200){ HttpEntity entity = response.getEntity(); InputStream in = null; OutputStream output = null; try{ in = entity.getContent(); String secondLevelCacheDir = context.getCacheDir() + fileName; File imageFile = new File(secondLevelCacheDir); output= new FileOutputStream(imageFile); IOUtilities.copy(in, output); output.flush(); } catch (IOException e) { Log.e("SAVING", "Could not load xml", e); } finally { IOUtilities.closeStream(in); IOUtilities.closeStream(output); dataReceived = true; } } }catch (SocketTimeoutException e){ //Handle not connecting to client !!!! Log.d("SocketTimeoutException Thrown", e.toString()); dataReceived = false; } catch (ClientProtocolException e) { //Handle not connecting to client !!!! Log.d("ClientProtocolException Thrown", e.toString()); dataReceived = false; }catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); dataReceived = false; Log.d("MalformedURLException Thrown", e.toString()); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); dataReceived = false; Log.d("IOException Thrown", e.toString()); } } return dataReceived; }

  • How to create a column that can never be updated?

    - by Randy Minder
    In SQL Server 2008, is it possible to create a column that can have a value inserted into it, but can never be updated? In other words, the column can have an initial value inserted into it, but once it contains a non-null value, it can never be changed. If possible, I would prefer to do it without using a trigger. Thanks - Randy

  • Scala 2.8: _ behaviour changed?

    - by Alexey Romanov
    Using XScalaWT, this compiled under Scala 2.7: class NodeView(parent: Composite) extends Composite(parent) { var nodeName: Label = null this.contains( label( nodeName = _ ) ) } With 2.8.0 RC1, I get this error: type mismatch; found : main.scala.NodeView required: org.eclipse.swt.widgets.Label The types are: label(setups: (Label => Unit)*)(parent: Composite) : Label contains(setups: (W => Unit)*) : W So it looks like _ now binds to the outer function instead of inner. Is this change intentional?

  • custom view with layout

    - by user270811
    ok, what i am trying to do is to embed a custom view in the default layout main.xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <com.lam.customview.CustomDisplayView android:id="@+id/custom_display_view1" android:layout_width="fill_parent" android:layout_height="fill_parent" /> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:id="@+id/prev" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="50" android:textAppearance="?android:attr/textAppearanceSmall" android:text="@string/prev" /> </LinearLayout> </LinearLayout> as you can see the class is called com.lam.customview.CustomDisplayView, with the id of custom_display_view1. now in the com.lam.customview.CustomDisplayView class, i want to use another layout called custom_display_view.xml because i don't want to programmatically create controls/widgets. custom_display_view.xml is just a button and an image, the content of which i want to change based on certain conditions: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:id="@+id/display_text_view1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <ImageView android:id="@+id/display_image_view1" android:layout_width="wrap_content" android:layout_height="wrap_content"> </ImageView> </LinearLayout> i tried to do: 1) public CustomDisplayView(Context context, AttributeSet attrs) { super(context, attrs); try { // register our interest in hearing about changes to our surface SurfaceHolder holder = getHolder(); holder.addCallback(this); View.inflate(context, R.layout.custom_display_view, null); ... but got this error, "03-08 20:33:15.711: ERROR/onCreate(10879): Binary XML file line #8: Error inflating class java.lang.reflect.Constructor ". 2) public CustomDisplayView(Context context, AttributeSet attrs) { super(context, attrs); try { // register our interest in hearing about changes to our surface SurfaceHolder holder = getHolder(); holder.addCallback(this); View.inflate(context, R.id.custom_display_view1, null); ... but got this error, "03-08 20:28:47.401: ERROR/CustomDisplayView(10806): Resource ID #0x7f050002 type #0x12 is not valid " also, if i do it this way, as someone has suggested, it's not clear to me how the custom_display_view.xml is associated with the custom view class. thanks.

  • References between Spring beans when using a NameSpaceHandler

    - by teabot
    I'm trying to use a Spring context namespace to build some existing configuration objects in an application. I have defined a context and pretty much have if working satisfactorily - however, I'd like one bean defined by my namespace to implicitly reference another: Consider the class named 'Node': public Class Node { private String aField; private Node nextNode; public Node(String aField, Node nextNode) { ... } Now in my Spring context I have something like so: <myns:container> <myns:node aField="nodeOne"/> <myns:node aField="nodeTwo"/> </myns:container> Now I'd like nodeOne.getNode() == nodeTwo to be true. So that nodeOne.getNode() and nodeTwo refer to the same bean instance. These are pretty much the relevant parts I have in my AbstractBeanDefinitionParser: public AbstractBeanDefinition parseInternal(Element element, ParserContext parserContext) { ... BeanDefinitionBuilder containerFactory = BeanDefinitionBuilder.rootBeanDefinition(ContainerFactoryBean.class); List<BeanDefinition> containerNodes = Lists.newArrayList(); String previousNodeBeanName; // iterate backwards over the 'node' elements for (int i = nodeElements.size() - 1; i >= 0; --i) { BeanDefinitionBuilder node = BeanDefinitionBuilder.rootBeanDefinition(Node.class); node.setScope(BeanDefinition.SCOPE_SINGLETON); String nodeField = nodeElements.getAttribute("aField"); node.addConstructorArgValue(nodeField); if (previousNodeBeanName != null) { node.addConstructorArgValue(new RuntimeBeanReference(previousNodeBeanName)); } else { node.addConstructorArgValue(null); } BeanDefinition nodeDefinition = node.getBeanDefinition(); previousNodeBeanName = "inner-node-" + nodeField; parserContext.getRegistry().registerBeanDefinition(previousNodeBeanName, nodeDefinition); containerNodes.add(node); } containerFactory.addPropertyValue("nodes", containerNodes); } When the application context is created my Node instances are created and recognized as singletons. Furthermore, the nextNode property is populated with a Node instance with the previous nodes configuration - however, it isn't the same instance. If I output a log message in Node's constructor I see two instances created for each node bean definition. I can think of a few workarounds myself but I'm keen to use the existing model. So can anyone tell me how I can pass these runtime bean references so that I get the correct singleton behaviour for my Node instances?
