  • Can't concatenate 2 arrays in PHP

    - by alex
    I've recently learned how to join 2 arrays using the + operator in PHP. But consider this code... $array = array('Item 1'); $array += array('Item 2'); var_dump($array); Output is array(1) { [0]= string(6) "Item 1" } Why does this not work? Skipping the shorthand and using $array = $array + array('Item 2') does not work either. Does it have something to do with the keys?

  • Favorite Visual Studio keyboard remappings?

    - by hoytster
    Stack Overflow has covered favorite short-cuts and add-ins, optimizations and preferences -- great topics all. If this one has been covered, I can't find it -- so thanks in advance for the link. What are your favorite Visual Studio keyboard remappings? Mine are motivated by the fact that I'm a touch-typist. Mouse, function keys, arrow keys, Home, End -- bleh. These are commands I do all day every day, so I've remapped them to sequences I can execute without moving my hands from the home row. The command that is remapped in Tools = Customize = [Keyboard] is shown in parentheses. I'm 100% positive that there are better remappings than these, so please post yours! Please include the command; oft times, figuring it out is a challenge. -- Hoytster Running the app and operating the debugger Ctrl+Q + Ctrl+R Run the application, in debug mode (Debug.Start) Ctrl+Q + Ctrl+Q Quit (stop) the application (Debug.StopDebugging) Ctrl+T Toggle a breakpoint at the current line (Debug.ToggleBreakpoint) Ctrl+K + Ctrl+I Step Into the method (Debug.StepInto) Ctrl+K + Ctrl+O Step Out of the method (Debug.StepOut) Ctrl+N Step over the method to the Next statement (Debug.StepOver) Ctrl+K + Ctrl+C Run the code, stopping at the Cursor position (Debug.RunToCursor) Ctrl+K + Ctrl+E Set then next statement to Execute (Debug.SetNextStatement) Navigating the code Ctrl+S Move a character LEFT (Edit.CharLeft) Ctrl+D Move a character RIGHT (Edit.CharRight) Ctrl+Q + Ctrl+S Move to the LEFT END of the current line (Edit.LineStart) Ctrl+Q + Ctrl+D Move to the RIGHT END of the current line (Edit.LineEnd) Ctrl+E Move a line UP (Edit.LineUp) Ctrl+X Move a line DOWN (Edit.LineDown) Ctrl+K + Ctrl+K Toggle (add or remove) bookmark (Edit.ToggleBookmark) Ctrl+K + Ctrl+N Move to the NEXT bookmark (Edit.NextBookmark) Ctrl+K + Ctrl+P Move to the PREVIOUS bookmark (Edit.PreviousBookmark) Ctrl+Q + Ctrl+W Save all modified Windows (File.SaveAll) Ctrl+L Find the NEXT instance of the search string (Edit.FindNext) Ctrl+K + Ctrl+L Find the PREVIOUS instance of the search string (Edit.FindPrevious) Ctrl+Q + Ctrl+L Drop down the list of open files (Window.ShowEzMDIFileList) The last sequence is like clicking the downward-facing triangle in the upper-right corner of the code editor window.

  • Inserting contact with android and querying the result uri returns no entries

    - by th0m4d
    Im developing an application which is dealing with the android contacts API. I implemented methods to insert, update and query contacts. So far everything worked (writing and reading contacts). At one point in my project Im experiencing a strange behaviour. I insert a contact using batch mode. I receive the URI to the RawContact. I do this in a background thread. // use batchmode for contact insertion ArrayList ops = new ArrayList(); int rawContactInsertIndex = ops.size(); // create rawContact ops.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI) .withValue(RawContacts.ACCOUNT_TYPE, ConstantsContract.ACCOUNT_TYPE) .withValue(RawContacts.ACCOUNT_NAME, accountName).build()); ops.add(createInsertOperation().withValueBackReference(Data.RAW_CONTACT_ID, rawContactInsertIndex) .withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE) .withValue(StructuredName.DISPLAY_NAME, displayName).withValue(StructuredName.GIVEN_NAME, firstName) .withValue(StructuredName.FAMILY_NAME, lastName).build()); //other data values... ContentProviderResult[] results = context.getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops); if (results.length 0) { result = results[0]; } Then i request and store the lookup uri RawContacts.getContactLookupUri(this.getContentResolver(), myContantRawContactUri); I am able to query the contact using the rawContactUri directly after inserting it (in the same thread). The lookup uri returns null. Uri rawContactUri = appUser.getRawContactUri(ctx); if (rawContactUri == null) { return null; } String lastPathSegment = rawContactUri.getLastPathSegment(); long rawContactId = Long.decode(lastPathSegment); if (rawContactUri != null) { contact = readContactWithID(rawContactId, ContactsContract.Data.RAW_CONTACT_ID); In a different place in the project I want to query the contact i inserted by the stored lookup uri or raw contact uri. Both return no rows from the content provider. I tried it in the main thread and in another background thread. ctx.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, ContactsContract.Data.RAW_CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?", new String[] { contactID + "", ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE }, null); My first thought was that it could be related to the context.getContentResolver(). But the android documentation states, that the ContentResolver objects scope is the application's package, so you have on ContentResolver for the whole app. Am I right? What am I doing wrong? Why does the same rawContactUri return the contact at one place and does not on another place? And why do I get a lookup uri from a raw contact, which is not working at all?

  • Malformed Farsi characters on AWT

    - by jlover2010
    Hi As i started programming by jdk6, i had no problem in text components neither in awt nor in swing. But for labels or titles of awt components, yes : I couldn't have Farsi characters displayable on AWTs just as simple as Swing by typing them into the source code. lets check this SSCCE : import javax.swing.*; import java.awt.*; import java.io.*; import java.util.Properties; public class EmptyFarsiCharsOnAWT extends JFrame{ public EmptyFarsiCharsOnAWT() { super("????"); setDefaultCloseOperation(3); setVisible(rootPaneCheckingEnabled); } public static void main(String[] args) throws AWTException, IOException { JFrame jFrame = new EmptyFarsiCharsOnAWT(); MenuItem show ; // approach 1 = HardCoding : /* show = new MenuItem("\u0646\u0645\u0627\u06cc\u0634"); * */ // approach 2 = using simple utf-8 saved text file : /* BufferedReader in = new BufferedReader(new FileReader("farsiLabels.txt")); String showLabel = in.readLine(); in.close(); show = new MenuItem(showLabel); * */ // approach 3 = using properties file : FileReader in = new FileReader("farsiLabels.properties"); Properties farsiLabels = new Properties(); farsiLabels.load(in); show = new MenuItem(farsiLabels.getProperty("tray.show")); PopupMenu popUp = new PopupMenu(); popUp.add(show); // creating Tray object Image iconIamge = Toolkit.getDefaultToolkit().getImage("greenIcon.png"); TrayIcon trayIcon = new TrayIcon(iconIamge, null, popUp); SystemTray tray = SystemTray.getSystemTray(); tray.add(trayIcon); jFrame.setIconImage(iconIamge); } } Yes, i know each of three approaches in source code does right when you may test it from IDE , but if you make a JAR contains just this class, by means of NetBeans project clean&build ,you won't see the expected characters and will just get EMPTY/BLANK SQUARES ! Unfortunately, opposed to other situations i encountered before, here there is no way to avoid using awt and make use of Swing in this case. And this was just an SSCCE i made to show the problem and my recent (also first) application suffers from this subject. Note: it seems i can not attach anything, so the contents od the text file would be this: ????? and the contents of properties file: #Sun May 02 09:45:10 IRDT 2010 tray.show=????? but i don't think by giving you the unicode-scape sequence, these would be necessary any way... And i think should have to let you know I posted this question a while ago in SDN and "the Java Ranch" forums and other native forums and still I'm watching... By the way i am using latest version of Netbeans IDE... I will be so grateful if anybody has a solution to this damn AWT components never rendered any Farsi character for me... Thanks in advance

  • How do I avoid web method parameters using proxy classes?

    - by Alex Angas
    I have a serializable POCO called DataUnification.ClientData.ClientInfo in a .NET class library project A. It's used in a parameter for a web service defined in project B: public XmlDocument CreateNewClient(ClientInfo ci, string system) I now wish to call this web method from project C and use the original DataUnification.ClientData.ClientInfo type in the parameter. However due to the generated proxy class it has now become a different type: WebServices.ClientDataUnification.DataUnificationWebService.ClientInfo. As far as .NET is concerned these are not the same types. How can I get around this?

  • Pattern Matching with XSLT

    - by genesis11
    I'm trying to match a pattern into a string in XSLT/XPath using the matches function, as follows: <xsl:when test="matches('awesome','awe')"> ... </xsl:when> However, in both Firefox 3.5.9 and IE8, it doesn't show up. IE8 tells me that "'matches' is not a valid XSLT or XPath function." Is this due to XSLT 2.0 not being supported, and is there a way around this?

    This may seem like a stupid question, so here goes: Other than parsing the string of FileInfo.FullPath for the drive letter to then use DriveInfo("c") etc to see if there is enough space to write this file. Is there a way to get the drive letter from FileInfo?

  • Retrieve Value Using Key From a Collection in Access 2000

    - by Mikecancook
    I know this is a simple question but it's aggravating me. If I have a key/value pair in a collection but I can't seem to get the value out using the key. I can get the key using the value but not vice versa. Is there some magical way to accomplish this? For example: Dim CycleList As Collection Dim Value as String Set CycleList = New Collection CycleList.Add 1, "Some Value" Value = CycleList(1) I've also tried CycleList.Item(1) and it's the same result, Value = 1.

  • Replace a div content with PHP

    - by Zakaria
    hi everybody, yesterday, I posted a question about "Hom to change a DIV id with a php function" and someone found the right answer with a regular expression. The problem is that I wanted to use this answer to aplly the method on other same problems. But, as I'm very bad at regular expressions, I couldn't. So the problem is that I upload some videos with FCKEditor and put the video script in my database and the result is like that: <div id="player959093-parent" style="text-align: center;float: left;"> <div style="border-style: none; height: 160px; width: 270px; overflow: hidden; background-color: rgb(220, 220, 220); background-image: url(http://localhost/fckeditor/editor/plugins/flvPlayer/flvPlayer.gif); background-repeat:no-repeat; background-position:center;"><script src="http://localhost/fckeditor/editor/plugins/flvPlayer/swfobject.js" type="text/javascript"></script> <div id="player959093"><a href="http://www.macromedia.com/go/getflashplayer">Get the Flash Player</a> to see this player. <div id="player959093-config" style="display: none;visibility: hidden;width: 0px;height:0px;overflow: hidden;">url=/editeur/images/flash/FOO.flv width=270 height=160 loop=false play=false downloadable=false fullscreen=true displayNavigation=true displayDigits=true align=left dispPlaylist=none playlistThumbs=false</div> </div> <script type="text/javascript"> var s1 = new SWFObject("http://localhost/editeur/javascript/fckeditor/editor/plugins/flvPlayer/mediaplayer.swf","single","270","160","7"); s1.addVariable("width","270"); s1.addVariable("height","160"); s1.addVariable("autostart","false"); s1.addVariable("file","/editeur/images/flash/FOO.flv"); s1.addVariable("repeat","false"); s1.addVariable("image",""); s1.addVariable("showdownload","false"); s1.addVariable("link","/editeur/images/flash/FOO.flv"); s1.addParam("allowfullscreen","true"); s1.addVariable("showdigits","true"); s1.addVariable("shownavigation","true"); s1.addVariable("logo",""); s1.write("player959093"); </script></div> </div> When I echo this content once in my PHP page, It works great. More than once, the videos doesn't appear. Which is obvious because of the unique ID. As you can see, the content has these ids: div id="player959093-parent" div id="player959093" div id="player959093-config s1.write("player959093"); So my question is: Is there a function that can replace the string "player959093" or concatenate it with some other string to resolve the display problem? Thank you very much, Regards.

  • Syntax proposition

    - by Knowing me knowing you
    I wonder if syntax as follows would be helpful in your opinion as a code readability improvent and self-commenting of code: std::map<std::string name, std::vector<int> scores> myMap; In this example it clearly says and no other comment is needed, what for we are using myMap variable. Looking forward to your opinions.

  • WPF: Copy Property to Clipboard

    - by Phil Sandler
    I have a string property in my ViewModel/Datacontext and want a simple button that copies its contents to the clipboard. Is this possible to do from XAML, or I do I need to handle the button click event (or use an ICommand) to accomplish this? I thought the following would work, but my button is always greyed out: <Button Width="100" Content="Copy" Command="ApplicationCommands.Copy" CommandTarget="{Binding MyStringProperty}"/>

  • Cross-thread operation not valid: Control accessed from a thread other than the thread it was create

    - by SilverHorse
    I have a scenario. (Windows Forms, C#, .NET) There is a main form which hosts some user control. The user control does some heavy data operation, such that if I directly call the Usercontrol_Load method the UI become nonresponsive for the duration for load method execution. To overcome this I load data on different thread (trying to change existing code as little as I can) I used a background worker thread which will be loading the data and when done will notify the application that it has done its work. Now came a real problem. All the UI (main form and its child usercontrols) was created on the primary main thread. In the LOAD method of the usercontrol I'm fetching data based on the values of some control (like textbox) on userControl. The pseudocode would look like this: //CODE 1 UserContrl1_LOadDataMethod() { if(textbox1.text=="MyName") <<======this gives exception { //Load data corresponding to "MyName". //Populate a globale variable List<string> which will be binded to grid at some later stage. } } The Exception it gave was Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on. To know more about this I did some googling and a suggestion came up like using the following code //CODE 2 UserContrl1_LOadDataMethod() { if(InvokeRequired) // Line #1 { this.Invoke(new MethodInvoker(UserContrl1_LOadDataMethod)); return; } if(textbox1.text=="MyName") //<<======Now it wont give exception** { //Load data correspondin to "MyName" //Populate a globale variable List<string> which will be binded to grid at some later stage } } BUT BUT BUT... it seems I'm back to square one. The Application again become nonresponsive. It seems to be due to the execution of line #1 if condition. The loading task is again done by the parent thread and not the third that I spawned. I don't know whether I perceived this right or wrong. I'm new to threading. How do I resolve this and also what is the effect of execution of Line#1 if block? The situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread. So only accessing the value so that the corresponding data can be fetched from the database.
