• use boolean with visible, as3

  - by VideoDnd

  Is there a better way to do use a use a boolean with visible? This animation blinks 30 times and stops. It works without error, but takes a moment to load. I would like to learn other ways of using visibility with conditionals. var timz:Timer = new Timer(100,30); timz.addEventListener(TimerEvent.TIMER, doIt); var condition:Number = 5; function doIt(event:TimerEvent):void{ trace("fire!"); if(condition=5){ box.visible = !box.visible; } } timz.start();

• Inserting an element into a sorted list

  - by Russell Cargill

  Ok I'm using getSharedPreferences to store my high score but before I fill it up I wanted to sort the scores into ascending order via and array, but if it finds a Score less than it in the first pos then it wont check the rest for the smallest? //function to add score to array and sort it public void addscoretoarray(int mScore){ for(int pos = 0; pos< score.length; pos++){ if(score[pos] > mScore){ //do nothing }else { //Add the score into that position score[pos] = mScore; break; } } sortArray(score); } should I call sortArray() before and after the loop to fix this problem or is there a better method to achive the same results? I should also mention that the sortArray(score) funtion is just calling Arrays.sort(score) where score is an array of mScore

• About the fix for the interference between Company mode and Yasnippet

  - by janoChen

  Emacs wiki says: Company does interfere with Yasnippet’s native behaviour. Here’s a quick fix: http://gist.github.com/265010 The code is the following: (define-key company-active-map "\t" 'company-yasnippet-or-completion) (defun company-yasnippet-or-completion () (interactive) (if (yas/expansion-at-point) (progn (company-abort) (yas/expand)) (company-complete-common))) (defun yas/expansion-at-point () "Tested with v0.6.1. Extracted from `yas/expand-1'" (first (yas/current-key))) I placed that code in my .emacs and the following message appeared: Warning (initialization): An error occurred while loading `c:/Documents and Settings/Alex.AUTOINSTALL.001/Application Data/.emacs.elc': Symbol's value as variable is void: company-active-map To ensure normal operation, you should investigate and remove the cause of the error in your initialization file. Start Emacs with the `--debug-init' option to view a complete error backtrace. Do I have to place the fix code inside a YASnippet's .el file? or in my .emacs (which throws me an error)?

  - by Macarse

  I am doing a custom title for my android app and I want to have a refresh button like the Twitter app. I am using a RelativeLayout an my ImageView is defined by: <ImageView android:id="@+id/title_refresh" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_menu_refresh" android:layout_alignParentRight="true"> </ImageView> In my Activity I have something like this: refreshView = (ImageView) findViewById(R.id.title_refresh); refreshView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { /* Make the refreshView turn into a progress bar. */ startService(new Intent(MyActivity.this, MyService.class)); } } I would like the ImageView to turn into a ProgressBar while I wait for my service to finish processing.

• android: Check if a View is bringed to front

  - by user329692

  Hi Guys! I made a custom component which simple extends a WebView This component is used into activities that are loaded from a tabhost. This component creates a timertask too. I'd like to execute the task only if the activity that contains the component is visible. Ex: public class MyWebView extends WebView { public MyWebView(Context context, AttributeSet as) { super(context,as); /** More code **/ TimerTask ttask = new TimerTask() { @Override public void run() { if (iamvisible) doStuff(); } }; timer = new Timer(); timer.schedule(ttask, refreshInterval * 1000, refreshInterval * 1000); } } How can I set the iamvisible variable? I tried overriding onWindowFocusChanged and onWindowVisibilityChanged but with no luck Regards in advance

• What's wrong with my logic (Java syntax)

  - by soda

  I'm trying to make a simple program that picks a random number and takes input from the user. The program should tell the user if the guess was hot (-/+ 5 units) or cold, but I never reach the else condition. Here's the section of code: public static void giveHint (int guess) { int min = guess - 5; int max = guess + 5; if ((guess > min) && (guess < max)) { System.out.println("Hot.."); } else { System.out.println("Cold.."); } }

• Adding to arrays and printing arrays in Java

  - by nfoggia

  I need help figuring out how to get the user to input a number of integers no more than 10, and then add them to an array and print them out from the array. The code I have below, when run, asks the user for the integers and then runs forever and doesn't work. What am I doing wrong? public static void main(String[] args) { Scanner input = new Scanner(System.in); // create a new scanner System.out.print("Enter integers between 1 and 100\n "); int[] nextNumber = new int[10]; int i = 0; int number = input.nextInt(); while (i < nextNumber.length){ i++; nextNumber[i] = number; number = input.nextInt(); } int a = 0; while (a < nextNumber.length){ a++; System.out.println(nextNumber[a]); }

• wcf possible to override the dipose of proxy

  - by pdiddy

  I'd like to override the Dispose method of generated proxy (ClientBase) because of the fact that disposing of a proxy calls Close and can throw an exception when the channel is faulted. The only way I came up was to create a partial class to my generatedproxy, make it inherit from IDisposable. : public partial class MyServiceProxy : IDisposable { #region IDisposable Members public void Dispose() { if (State != System.ServiceModel.CommunicationState.Faulted) Close(); else Abort(); } #endregion } I did some test and my Dipose method is indeed called. Do you see any issue with this strategy? Also, I don't like the fact that I'll have to create this partial class for every generated proxy. It be nice if I was able to make my proxy inherit from a base class...

• UInt32 to IntPtr

  - by ffenix

  I have the following problem: public class ListenThread : SocketInvoke { [DllImport("Ws2_32", CharSet = CharSet.Auto)] public unsafe static extern UInt32 WSAWaitForMultipleEvents(UInt32 cEvents, IntPtr hEventObject, UInt32 fWaitAll, UInt32 dwTimeout, Boolean fAlertable); public void ListenConnections(NetSharedData data) { while (true) { unsafe { if (WSAWaitForMultipleEvents((UInt32)1, data.signal, (UInt32)0, (UInt32)100, false) != WSA_WAIT_TIMEOUT) { } } } } data.signal is a UInt32 how i can cast it to IntPtr?, i try: IntPtr signal = (IntPtr)data.signal; but it doesn't work because i need a pointer to data.signal (UInt32) type and not the int value as an pointer, that will make a memory exception. An C++ example of what i need: int signal = 0; int* psignal = &signal;

• Problem passing a reference as a named parameter to a variadic function

  - by Michael Mrozek

  I'm having problems in Visual Studio 2003 with the following: void foo(const char*& str, ...) { va_list args; va_start(args, str); const char* foo; while((foo = va_arg(args, const char*)) != NULL) { printf("%s\n", foo); } } When I call it: const char* one = "one"; foo(one, "two", "three", NULL); I get: Access violation reading location 0xcccccccc on the printf() line -- va_arg() returned 0xcccccccc. I finally discovered it's the first parameter being a reference that breaks it -- if I make it a normal char* everything is fine. It doesn't seem to matter what the type is; being a reference causes it to fail at runtime. Is this a known problem with VS2003, or is there some way in which that's legal behavior? It doesn't happen in GCC; I haven't tested with newer Visual Studios to see if the behavior goes away

• any way to get sharepoint groups with a given site url

  - by standley-nguyen

  Hi all. I'm getting a stuck. Suppose that I create 5 sites. For each one, I create a few sharepoint groups. So, I create a dropdownlist control to bind 5 sites and when I click on any site there, I will get sharepoint groups created on it. But I always see the dropdownlist used to bind these groups still never change. I mean it only binds a few default groups in sahrepoint everytime. The new created groups is not. And I have confusion like this web.AssociatedGroups web.Groups web.SiteGroups which one we will use this case ? Please guide me Here my snippet code private void BindSPGroupsToDropDownList(DropDownList ddl, string siteUrl) { ddl.Items.Clear(); try { SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(siteUrl)) { using (SPWeb web = site.OpenWeb()) { //web.SiteGroups foreach (SPGroup spGroup in web.Groups) { ddl.Items.Add(new ListItem(spGroup.Name.Trim(), spGroup.ID.ToString())); } } } }); } } thanks in advance

• snprintf and Visual Studio 2010

  - by Andrew

  I'm unfortunate enough to be stuck using VS 2010 for a project, and noticed the following code still doesn't build using the non-standards compliant compiler: #include <stdio.h> #include <stdlib.h> int main (void) { char buffer[512]; snprintf(buffer, sizeof(buffer), "SomeString"); return 0; } (fails compilation with the error: C3861: 'snprintf': identifier not found) I remember this being the case way back with VS 2005 and am shocked to see it still hasn't been fixed. Does any one know if Microsoft has any plans to move their standard C libraries into the year 2010?
