• Clear Bitmap data and make it null

  - by Arun

  I am working in an android application and I want to Clear my Bitmap data. The scenario is that I am taking a screen capture of an Widget(Imageview) and I am storing it in a Bitmap. This action comes in a Button click. SO after some time I get a Memory error. So I want to clear the values in the bitmap. So to do that I have done the following code : The BitMap variable is mCaptureImageBitmap public void ButtonClick(View v) { mCaptureImageBitmap.recycle(); mCaptureImageBitmap=null; View ve = findViewById(R.id.mainscreenGlViewRelativeLayout); ve.setDrawingCacheEnabled(true); mCaptureImageBitmap = ve.getDrawingCache(); } But I get an error of NullPoint exception. Please help me

• Writing the code by dividing it into more files in cocoatouch.

  - by srikanth rongali

  My problem is, I need a background image, a sprite(with animation) on left edge, another sprite(with animation) at other edge, a number count animation 1-2-3 at middle. I got all these when I wrote all in same file.(like [self addChild:label], [self addChild:sprite].., But in this it needs touch enables for both sprites separately, and touchDisabled to the remaining screen. So thought of writing in different files. But now it is not working. I kept one sprite, background image, numbercount in one file and another spritr in other file. Either I am getting the second sprite or the (sprite+background+numberCount) is displayed. This is my problem. plz give me solution. Thank You

• Event is causing an error, but I can't catch the exception

  - by proudgeekdad

  A developer has created a custom control in ASP.NET using VB.NET. The custom control uses a repeater. In certain scenarios, the rpt_ItemDataBound event is encountering a data error. My goal is rather than having the user see the yellow screen of death, give the user a friendlier error explaining exactly what the data error is. I figured I would be able to use a Try/Catch block as shown below throw the exception, however, it appears that the event has nowhere to be thrown to and stops executing at the "End Try" line. Protected Sub rpt_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.RepeaterItemEventArgs) Handles rpt1.ItemDataBound, rpt2.ItemDataBound Try ProcessBadData... Catch ex As Exception Throw ex End Try End Sub In VB.NET, I can find where the repeater's DataSource is being set, however, I can not find a DataBind event. Any ideas how I can capture the exception in this ASCX control so I can report it to the user?

• cropped layout on the Android avd emulator

  - by SpellBound

  My application layout looks good on two slightly different avds I created in the development environment using Eclipse. However when I try to run these devices in the Emulator as standalone I see some missing buttons and cropped edges on the screen. I used the apk generated by Eclipse and installed it in the devices using adb - install. I want to know what the problem is. Also, any general guidelines to write an app that can run on any Android device for a given version. Thanks in advance.

• Refresh the Parent form of "Call_form" after Child form is closed in Oracle 10g

  - by DotNetDan

  What I need is: what trigger to use and where to put it. I will give you an example of what I am doing. I have a Contract form that is fully editable except the contract financial areas, which is read only. I want the user to press a button called, “change rates” and that will have a trigger “When-Button-Pressed” and call_form(UpdateFinancials);. Now, in this screen, I have the user change the financial information such as increase the contract from 50k to 100k. Then the user saves and exits. This will then close the child form "UpdateFinancials" and show the parent form "ContractForm". The problem is, it still has all the old information on it. I need the information in the form to refresh when it gets back from the child form of the Call_Form function.

• How can we make the video play in a small view and also filling that whole view?

  - by wolverine

  I have added an imageView of size 300*300 into the interface in my ipad project. I can play the video fullscreen using MPMOviePlayerController. And I am trying to make it play in the imageView by using the following code. [imageView1 addSubview:moviePlayer.view]; [self.moviePlayer play]; Its playing but not as fullscreen and also not filling the whole imageview. Its kind of playing on the top quarter of the view and that too not the whole movie view - about lower right 60% only. How can I fix this? How can I make the movie play on the whole imageview like it plays on the full screen?

• Is it faster to count down than it is to count up?

  - by Bob

  Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?

• Perl: print back to beginning of line

  - by Pmarcoen

  Okay, so what I'm trying to do is print out a percentage complete to my command line, now, I would like this to simply 'update' the number shown on the screen. So somehow go back to the beginning of the line and change it. For example the windows relog.exe command-line utility (which can convert a .blg file to a .csv file) does this. If you run it, it will display a percentage complete. Now this is probably written in C++. I don't know if this is possible in perl as well ?

• Is Android IPC plumbing exposed in any official and/or supported way?

  - by mathrick

  I'm interested in knowing how much the IPC mechanisms are meant to be exposed to the outside world. That is, if I wanted to impersonate a dalvik VM instance without having my app actually written in Java, am I allowed to do so, or will the protocol change the next time I look away from the screen? If it's allowed, what are the stability guarantees or lack thereof? Is there anything like documentation, or am I supposed just to read the fine sources on android.git.kernel.org? The purpose of it all would be to write apps in !Java languages while retaining the ability to construct GUIs. I don't care or mind if the code is technically inside a dalvik process as a JNI callout, what I'm interested in is "if I'm really good at pretending I'm Java over the wire, can I do everything actual Java code can? Or is there something that's only available as Java bytecode and nothing else?"

• make Ruby script run once a second

  - by Matt Hintzke

  I have a ruby script that needs to run about 1 time a second. What I am doing is using a ruby script to keep track of modifications of files in a directory. I want the script to run once a second so that the modifications are updated in "live" time. Basically, I want my script to do the same kind of thing as running "top" on a unix shell. Where the screen is updated every second or so. Is there an equivalent to setInterval in ruby like there is in javascript? Thanks

• Can I save my app's state at close time in iPhone OS?

  - by Steve

  I have an app that functions much like an ebook. I have a bunch of textual information in various languages that is accessible through a number of drill down methods. When a user wants to get into where they were reading last, they currently have to navigate through the section and chapter menus to get back to where they were. An ideal solution for this would be to setup a bookmark system, which I am considering. But if I remember correctly, when iPhone OS 4 was announced, they seemed to make a big deal of the added ability to save the state of an app. Does that mean that someone using my reader app would be able to just exit right out, do whatever, and then when they came back in, it would be the reading screen just as they left it? I don't know much about how to setup a bookmarking system, I suppose it would be worth investigating, but I would probably want to just hold off for iPhone OS 4 if that is indeed what it will be capable of doing. Any thoughts or insights would be appreciated!!

• How will web programming change as tablet PC's become more prevalent?

  - by MrGumbe

  In case you've been living under a rock, you may have noticed that Apple introduced a tablet PC. HP, Microsoft, Google, and others aren't too far behind. A lot of discussion and thought has been put into how a user would interact with traditional applications in a large touch screen environment, but how do you think this will affect the user interface of traditional web programming? What do you think will have to change with our current HTML controls? What new kinds of controls will be possible if we have touch-and-drag technology on our web pages?

• Android: Touch seriously slowing my application

  - by Jason Rogers

  Hi all, I've been raking my brains on this one for a while. when I'm running my application (opengl game) eveyrthing goes fine but when I touch the screen my application slows down quite seriously (not noticeable on powerful phones like the nexus one, but on the htc magic it gets quite annoying). I did a trace and found out that the touch events seem to be handled in a different thread and even if it doesn't take so much processing time I think androids ability to switch between threads is not so good... What is the best way to handle touch when speed is an issue ? Currently I'm using : in the GLSurfaceView @Override public boolean onTouchEvent(MotionEvent event) { GameHandler.onTouchEvent(event); return true; } Any ideas are welcome

• How to hide action bar before activity is created, and then show it again?

  - by Ilya Izhovkin

  I need to implements splash screen in my honeycomb app. I use this code in activity's onCreate to show splash: setContentView(R.layout.splash); getActionBar().hide(); and this code to show main UI after some time: setContentView(R.layout.main); getActionBar().show(); But before onCreate is called and splash appears, there is small amount of time when action bar shown. How can I made it not to show? I tried to apply theme to activity without action bar: <item name="android:windowActionBar">false</item> but in that case getActionBar() always returns null and I found no way to show it again.

• Bitmap size exceeds VM budget after second load

  - by jonny

  This is driving me crazy. I have a game which has a bitmap as the background, this is big so I scale it down and this works fine. However when I navigate to another activity and then reload the game screen it crashes on drawing the background. I am calling recycle on all the bitmaps and setting them to null on onDestroy() but this doesn't help. Any ideas and if not how can I debug the memory to see at which step its growing. I looked at getting the heap but nothing of any size is on there really. Thanks.

• How to check if aspect ratio auto adjustment is enabled in monitor

  - by kFk

  Game application is written in C++ and uses DirectX 8. I am getting a maximum monitor resolution to calculate it's aspect ratio. Then I use this value to fix game rendering (scale and set clipping to receive normal 4:3 image with black borders on wide screen monitors). How can I check if monitor is using aspect ratio auto adjustment now? Because my scaling plus monitor scaling makes resulting image overscaled. Thanks EDIT: I saw correct different monitor resolution handling with or without aspect ratio auto adjustment in "Royal Envoy" casual game. But don't know how do they do this.

• How do I stop setNeedsDisplayInRect / drawRect coalescence?

  - by No One in Particular

  When programming my app, I get to the point where I have to update two rectangles on the screen. So I call [self setNeedsDisplayInRect:rect1] and then [self setNeedsDisplayInRect:rect2]. When my drawRect method is called, the rectangle parameter is the smallest rectangle which contains both rect1 and rect2. I can handle this with no problem, but when the two rectangles are far apart, then I am updating a lot of real estate with no gain. In this case, I would just like to repaint my two small rectangles. So my question is how can I prevent the underlying system from coalescing my two calls into one?

• How to check if canvas objects overlap each other

  - by ?????? ???????

  I'm trying to check if two objects (e.g. a rectangle and a triangle) on a HTML5 canvas are overlapping each other. Currently I can only check that by looking at the screen (having set globalCompositeOperation='lighter'). My first idea would have been to scan all over the canvas if the "lighter" (compare code snippet above) color exists in the canvas. But therefor I would have to look at every single pixel which was rather costly for what I need. Is there a (better) alternative to automatically check if they are overlapping? Best regards.

• Setting Global Variables in VBA

  - by dennis96411

  I'm currently making an "OS" in PowerPoint and I need to know how to set global variables for the settings. I made a module called "Settings" containing: Public Sub Settings() Option Explicit Public UserName, UserIcon, Background, BrowserHomePage As String Public SetupComplete As Boolean SetupComplete = False UserName = "Administrator" UserIcon = Nothing Background = Nothing BrowserHomePage = Nothing 'Set the variables UserName.Text = UserName End Sub Now on the "log in" screen, I have a text box named "UserName". I then made a button just to test out the variables. The button does this: Private Sub CommandButton1_Click() UserName.Value = UserName End Sub The text box has no value when I click the button. I'm super new at VBA, and would like to know how to do this. Also, if anyone knows how to automatically execute codes when starting the PowerPoint, that would be fantastic.

• How does R treat positional arguments

  - by inspectorG4dget

  I'm a python guy and very new to R (so far, all I've done is copy-paste code and screen-shot the resulting, graph). I would now like to actually learn the language so that I can draw useful plots (right now, I am trying to plot this). In attempting my first plot, I came across this function call: sets_options("universe", seq(from = 0, to = 25, by = 0.1)) Now, I would like to know if I can achieve the same result by calling sets_options("universe", seq(0, 25, 0.1)) The help page for seq doesn't speak to this specifically (or I'm not reading it correctly), so I was hoping someone could shed some light on how R handles positional arguments I tried calling the function that way in R and it worked (no syntax errors, etc), but I don't know how to test the output of that function, so I'm forced to ask here
