• Data Formatters temporarily unavailable

  - by iphone newbie

  I'm currently working on an iPhone app. This app has a login screen, also a signup screen. After the user has successfully signed up, I dismiss the signup view, then the app automatically logs in using the created account. After which, the login view is dismissed, showing the main view. I'm trying to modify this by immediately dismissing the login view, since I already have the account details of the user when the signup is successful. Basically, the ideal flow is: after the user successfully signs up, I save the username and password in a singleton class, then dismiss the signup view. When I get to the parent view (which is the login screen), I have a variable that checks if there was a successful signup. If that variable is true, I want to immediately dismiss the login view. However, I come across this error message: Data Formatters temporarily unavailable, will re-try after a 'continue'. (Unknown error loading shared library "/Developer/usr/lib/libXcodeDebuggerSupport.dylib") I'm not really sure why this happens. I have no problems dismissing the login view when I go through the actual login procedure - which of course also dismisses the login view if the user inputs a correct username and password. I'm not exactly sure, but I'm starting to think that the iPhone cannot handle dismissing 2 view controllers almost at the same time. Is it possible that I'm dismissing the login view too quickly? Is that a factor? Is there anyway for me to be able to dismiss 2 view controllers almost simultaneously without coming across this error message?

• Android Canvas Coordinate System

  - by Mitch

  I'm trying to find information on how to change the coordinate system for the canvas. I have some vector data I'd like to draw to a canvas using things like circles and lines, but the data's coordinate system doesn't match the canvas coordinate system. Is there a way to map the units I'm using to the screen's units? I'm drawing to an ImageView which isn't taking up the entire display. If I have to do my own calculations prior to each drawing call, how to I find the width and height of my ImageView? The getWidth() and getHeight() calls I tried seem to be returning the entire canvas size and not the size of the ImageView which isn't helpful. I see some matrix stuff, is that something that will work for me? I tried to use the "public void scale(float sx, float sy)", but that works more like a pixel level zoom rather than a vector scale function by expanding each pixel. This means if the dimensions are increased to fit the screen, the line thickness is also increased. Update: After some research I'm starting to think there's no way to change coordinate systems to something else. I'll need to map all my coordinates to the screen's pixel coordinates and do so by modifying each vector. The getWidth() and getHeight() seem to be working better for me now. I can say what was wrong, but I suspect I can't use these methods inside the constructor.

• Determine size of SizeToContent WPF Window before its rendered

  - by DudeFX

  I have a window in my WPF application that is displayed on occasion. When it is shown it is faded in with an annimation, and when closed it is faded out. Nothing fancy, just a storyboard that modifies the opacity. Actually the window is never really closed, the opacity is just faded out to 0 where it remains until its to be displayed again. This window is an informative window and doesn't always show the same content. It is sized to content (Width and Height) and works well in that regard. The user chooses the basic area of the screen for it to be displayed (TopLeft, TopRight, Center, BottomLeft, BottomRight). Before the window is faded in the content is updated. Because the window is sized to content it increases or descreases in size. The width and height can change. When positioning the window, lets say, in the bottom right corner, I simply take the WorkingArea of the screen (width and height) and then minus the width/height of the window to get the Top and Left position that I need. The logic works, but the trouble I am having is the Window's Height and Width is not returning the size it is after the content was updated, but is returning the size it was the last time it was displayed. I am assuming this is because it hasn't yet been rendered with the new content. This causes me grief becuase if the Window is larger than it was the last time it obviously extends off the screen. I tried positioning the window in the OnContentRendered event, but this only fires once when the Window is created, not after the content has been updated, when the opacity is set to 0. Does anyone have any idea how I might get an accurate width and height of this window before it is faded in? Any help would be appreciated!!

• JQGrid datatype as Ajax function not getting called

• Newbie: How to set attribute of the relative layout in my case??

  - by Leem

  I would like to divide my screen into 4 equal areas like ?.Each one of the four area is a linear layout. I tried to use relative layout to hold four linear layout like below: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:id="@+id/up_left_area" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#ffff66" > <TextView android:id="@+id/label1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="UP LEFT"/> </LinearLayout> <LinearLayout android:id="@+id/up_right_area" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_toRightOf="@id/up_left_area" android:background="#ccffff"> <TextView android:id="@+id/label2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="UP RIGHT"/> </LinearLayout> <LinearLayout android:id="@+id/down_left_area" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_below="@id/up_left_area" android:background="#66cc33" > <TextView android:id="@+id/label3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="DOWN LEFT"/> </LinearLayout> <LinearLayout android:id="@+id/down_right_area" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_below="@id/up_right_area" android:layout_toRightOf="@id/down_left_area" android:background="#cc6600"> <TextView android:id="@+id/label4" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="DOWN RIGHT"/> </LinearLayout> </RelativeLayout> With the above xml layout code, I do get 4 areas on the screen, but they are not equal sized. How to modify my code to have equal sized 4 areas on the screen like ? ?

• How to create a UIScrollView Programmatically?

  - by Wayfarer

  Alright, so the key here is I'm not using IB at all, because the View I'm working with is created programmatically. The UIView covers the lower half the screen, and has a bunch of buttons on it. However, I want to add more buttons to the UIView, without making it any larger. To do so, I want to make a UIScrollView inside the view, which will allow me to add more buttons off screen so the user can scroll to them. I think that's how it works. self.manaView = [[[UIView alloc] initWithFrame:frame] autorelease]; self.manaView.backgroundColor = [UIColor purpleColor]; UIScrollView *scroll = [UIScrollView alloc]; scroll.contentSize = CGSizeMake(320, 400); scroll.showsHorizontalScrollIndicator = YES; [self.manaView addSubview:scroll]; The first part of the code iniates my UIView, which works great, but I can't figure out how to make the UIScrollView programmatically and add it to the view, and then add the buttons to it. UIButton *ret2 = [UIButton buttonWithType:UIButtonTypeRoundedRect]; ret2.tag = 102; ret2.frame = CGRectMake(255, 5, 60, 50); [ret2 setTitle:@"Return" forState:UIControlStateNormal]; [ret2 addTarget:self action:@selector(flipAction:) forControlEvents:UIControlEventTouchUpInside]; [scroll addSubview:ret2]; When I did that, the button simply disappeared off my screen. So How do I do this correctly? Thank you for your help!

• Simple iPhone drawing app with Quartz 2D

  - by Mr guy 4

  I am making a simple iPhone drawing program as a personal side-project. I capture touches event in a subclassed UIView and render the actual stuff to a seperate CGLayer. After each render, I call [self setNeedsLayout] and in the drawRect: method I draw the CGLayer to the screen context. This all works great and performs decently for drawing rectangles. However, I just want a simple "freehand" mode like a lot of other iPhone applications have. The way I thought to do this was to create a CGMutablePath, and simply: CGMutablePathRef path; -(void)touchBegan { path = CGMutablePathCreate(); } -(void)touchMoved { CGPathMoveToPoint(path,NULL,x,y); CGPathAddLineToPoint(path,NULL,x,y); } -(void)drawRect:(CGContextRef)context { CGContextBeginPath(context); CGContextAddPath(context,path); CGContextStrokePath(context); } However, after drawing for more than 1 second, performance degrades miserably. I would just draw each line into the off-screen CGLayer, if it were not for variable opacity! The less-than-100% opacity causes dots to be left on the screen connecting the lines. I have looked at CGContextSetBlendingMode() but alas I cannot find an answer. Can anyone point me in the right direction? Other iPhone apps are able to do this with very good efficiency.

• How do I break down an NSTimeInterval into year, months, days, hours, minutes and seconds on iPhone?

  - by willc2

  I have a time interval that spans years and I want all the time components from year down to seconds. My first thought is to integer divide the time interval by seconds in a year, subtract that from a running total of seconds, divide that by seconds in a month, subtract that from the running total and so on. That just seems convoluted and I've read that whenever you are doing something that looks convoluted, there is probably a built-in method. Is there? I integrated Alex's 2nd method into my code. It's in a method called by a UIDatePicker in my interface. NSDate *now = [NSDate date]; NSDate *then = self.datePicker.date; NSTimeInterval howLong = [now timeIntervalSinceDate:then]; NSDate *date = [NSDate dateWithTimeIntervalSince1970:howLong]; NSString *dateStr = [date description]; const char *dateStrPtr = [dateStr UTF8String]; int year, month, day, hour, minute, sec; sscanf(dateStrPtr, "%d-%d-%d %d:%d:%d", &year, &month, &day, &hour, &minute, &sec); year -= 1970; NSLog(@"%d years\n%d months\n%d days\n%d hours\n%d minutes\n%d seconds", year, month, day, hour, minute, sec); When I set the date picker to a date 1 year and 1 day in the past, I get: 1 years 1 months 1 days 16 hours 0 minutes 20 seconds which is 1 month and 16 hours off. If I set the date picker to 1 day in the past, I am off by the same amount. Update: I have an app that calculates your age in years, given your birthday (set from a UIDatePicker), yet it was often off. This proves there was an inaccuracy, but I can't figure out where it comes from, can you?

• Need advice or pointers on Release Management Strategies

  - by Murray

  I look after an internal web based (Java, JSP, Mediasurface, etc.) system that is in constant use (24/5). Users raise tickets for enhancements, bug fixes and other business changes. These issues are signed off individually and assigned to one of three or four developers. Once the issue is complete it is built and the code only committed to SVN. The changed files (templates, html, classes, jsp) are then copied to a dev server and committed to a different repository from where they are checked out to the UAT server for testing. (this often requires the Tomcat service to be restarted and occasionally the Mediasurface service as well). The users then test and either reject or approve the release. If approved the edited files are checked out to the Live server and the same process as with UAT undertaken. If rejected the developer makes the relevant changes and starts the release process again. This is all done manually without much control. Where different developers are working on similar files, changes sometimes get overwritten by builds done on out of sync code in other cases changes in UAT are moved to live in error as they are mixed up in files associated with a signed off release. I would like to move this to a more controlled and automated process where all source code and output files are held in SVN and releases to Dev, UAT and Live managed by a CI system (We have TeamCity in house for our .NET applications). My question is on how to manage the releases of multiple changes where some will be signed off and moved on and others rejected and returned to the developer. The changes may be on overlapping files and simply merging each release in to a Release Branch means that the rejected changes would have to be backed out of the branch. Is there a way to manage this using SVN and CI or will I simply have to live with the current system.

• LinearLayout not expanding inside a ScrollView

  - by Felix

  I have a LinearLayout inside a ScrollView that has android:layout_height="fill_parent", but it doesn't expand to the full height of the ScrollView. My layout looks something like: level layout layout_width layout_height 1 LinearLayout fill_parent fill_parent 2 LinearLayout fill_parent wrap_content 3 (some irrelevant stuff) 2 ScrollView fill_parent fill_parent <-- this expands full height 3 LinearLayout fill_parent fill_parent <-- this does not (has orientation=vertical) (following stuff probably are irrelevant, but just to be sure:) 4 TextView fill_parent fill_parent 4 LinearLayout fill_parent wrap_content I can see that the LinearLayout doesn't expand the full height of the ScrollView because in Eclipse in Android Layout Editor, if I select the ScrollView (in the Outline panel) it is highlighted with a red border that fills the screen to the bottom but when I select the LinearLayout its highlight doesn't expand to the bottom of the screen. How can I get it to do so? The effect I'm trying to achieve is to have some text and a button below it (inside the LinearLayout in level 4 there's just a button). The text can be big enough to need a scrollbar, in which case I want the user to have to scroll down in order to see the button. In case the text is not big enough for a scroll bar, I want the LinearLayout containing the button to stick to the bottom of the screen.

• IE innerHTML chops sentence if the last word contains '&' (ampersand)

  - by Mandai

  I am trying to populate a DOM element with ID 'myElement'. The content which I'm populating is a mix of text and HTML elements. Assume following is the content I wish to populate in my DOM element. var x = "<b>Success</b> is a matter of hard work &luck"; I tried using innerHTML as follows, document.getElementById("myElement").innerHTML=x; This resulted in chopping off of the last word in my sentence. Apparently, the problem is due to the '&' character present in the last word. I played around with the '&' and innerHTML and following are my observations. If the last word of the content is less than 10 characters and if it has a '&' character present in it, innerHTML chops off the sentence at '&'. This problem does not happen in firefox. If I use innerText the last word is in tact but then all the HTML tags which are part of the content becomes plain text. I tried populating through jQuery's #html method, $("#myElement").html(x); This approach solves the problem in IE but not in chrome. How can I insert a HTML content with a last word containing '&' without it being chopped off in all browsers?

• SubSonic 3 ignoring columns in Select()

  - by jessegavin

  I have a table like so.. CREATE TABLE [dbo].[Locations_Hours]( [LocationID] [int] NOT NULL, [sun_open] [nvarchar](10) NULL, [sun_close] [nvarchar](10) NULL, [mon_open] [nvarchar](10) NULL, [mon_close] [nvarchar](10) NULL, [tue_open] [nvarchar](10) NULL, [tue_close] [nvarchar](10) NULL, [wed_open] [nvarchar](10) NULL, [wed_close] [nvarchar](10) NULL, [thu_open] [nvarchar](10) NULL, [thu_close] [nvarchar](10) NULL, [fri_open] [nvarchar](10) NULL, [fri_close] [nvarchar](10) NULL, [sat_open] [nvarchar](10) NULL, [sat_close] [nvarchar](10) NULL, [StoreNumber] [int] NULL, [LocationHourID] [int] IDENTITY(1,1) NOT NULL, CONSTRAINT [PK_Locations_Hours] PRIMARY KEY CLUSTERED ( [LocationHourID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] And SubSonic 3 is generating a class with the following properties int LocationID string monopen string monclose string tueopen string tueclose string wedopen string wedclose string thuopen string thuclose string friopen string friclose string satopen string satclose string sunopen string sunclose int? StoreNumber int LocationHourID When I try to perform a query against this class like so.. var result = DB.LocationHours.Where(o => o.LocationID == _locationId); This is the resulting SQL query that SubSonic generates. SELECT [t0].[LocationHourID], [t0].[LocationID], [t0].[StoreNumber] FROM [dbo].[Locations_Hours] AS t0 WHERE ([t0].[LocationID] = 4019) I cannot figure out why SubSonic is omitting the nvarchar fields when it generates the SELECT statement. Anyone got any ideas?

• Process.CloseMainWindow() not working

  - by gehho

  I start the Windows On-Screen-Keyboard like that: s_onScreenKeyboard = new Process(); s_onScreenKeyboard.StartInfo = new ProcessStartInfo("osk.exe"); s_onScreenKeyboard.EnableRaisingEvents = true; s_onScreenKeyboard.Exited += new EventHandler(s_onScreenKeyboard_Exited); s_onScreenKeyboard.Start(); This works fine, but when I try to stop it using the following code, it does nothing: s_onScreenKeyboard.CloseMainWindow(); if (!s_onScreenKeyboard.HasExited) { if (!s_onScreenKeyboard.WaitForExit(1000)) { s_onScreenKeyboard.Close(); //s_onScreenKeyboard.Kill(); } } When uncommenting s_onScreenKeyboard.Kill(); it is closed, but the problem is that osk.exe obviously uses another process called "msswchx.exe" which is not closed if I simply kill the OSK process. This way, I would end up with hundreds of these processes which is not what I want. Another strange thing is that the CloseMainWindow() call worked at some time, but then it suddenly did not work anymore, and I do not remember what has changed. Any ideas? Background: I am implementing an On-Screen-Keyboard for my application because it should work with a touchscreen. It is important that the keyboard layout matches the layout which is configured in Windows since the application will be shipped to many different countries. Therefore, instead of implementing a custom keyboard control with approx. 537 keyboard layouts (exaggerating a little here...), I wanted to utilize the Windows built-in On-Screen-Keyboard which adapts to the selected keyboard layout automatically, saving a lot of work for me.

• UiModeManager - NightMode (FroYo)

  - by Kaloer

  Hi there, I have been trying to turn off the buttons' light in my application using the UiModeManager's nightmode function. The default Desk Clock application (Nexus One) turns off the buttons' light when it is dimmed, and I want to do this as well. I've tried using the following code: UiModeManager mgr = (UiModeManager) getSystemService(UI_MODE_SERVICE); mgr.setNightMode(UiModeManager.MODE_NIGHT_YES); The UiModeManager.setNightMode(int mode) documentation says this: Sets the night mode. Changes to the night mode are only effective when the car or desk mode is enabled on a device. Does that mean that the device has to be physically in a desk dock? I can set the device to car mode using the UiModeManager.enableCarMode(int flags) method. This works fine, but it doesn't turn off the lights, it only dims the screen's backlight. Is there a way to set the device into desk mode without using a physical desk dock? As the FroYo source code is not yet released, I cannot look at the build-in Desk Clock application. Thanks in advantage.

• How to add Custom View +Relative Layout into ViewGroup

  - by TimothyMiller

  Hi I am creating a View where you can draw on the screen, using a view, where I would like to have a button/titlebar drawn at the top of the screen. Here is my current code public class FingerPaint extends Activity implements ColorPickerDialog.OnColorChangedListener { private Paint mPaint; private MyView mView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); LinearLayout main = new LinearLayout(this); mView = new MyView(this); main.addView(this.getLayoutInflater().inflate( R.layout.topbar, null )); main.addView(mView); main.bringChildToFront(mView); setContentView(main); // mView.addView(this.getLayoutInflater().inflate( R.layout.topbar, null )); mPaint = new Paint(); mPaint.setAntiAlias(true); mPaint.setDither(true); mPaint.setColor(0xFFFF0000); mPaint.setStyle(Paint.Style.STROKE); mPaint.setStrokeJoin(Paint.Join.ROUND); mPaint.setStrokeCap(Paint.Cap.ROUND); mPaint.setStrokeWidth(12); mBitmaps=new Bitmap[100]; location=0; actualSize=0; mEmboss = new EmbossMaskFilter(new float[] { 1, 1, 1 }, 0.4f, 6, 3.5f); mBlur = new BlurMaskFilter(8, BlurMaskFilter.Blur.NORMAL); setContentView(main); } public class MyView extends View{ ......... } But when run, only the topbar.xml view is shown. I want the status bar from topbar and the rest down to be from the myView (for drawing on the screen like paint). Am I using ViewGroup properly?

• Android: Creating a Scrollable Layout

  - by MD

  I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now. The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application. Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through. I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful. EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)

• Android layout with sqare buttons

  - by Mannaz

  I want to make a layout similar to this one: Four square buttons on the screen - each of those using half of the screen with/screen height (whichever is smaler). I already tried to achieve this by using a LinearLayoutbut the buttons are ending up using the correct width, but still having the height of the background (not square any more). <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_width="fill_parent" android:text="@string/sights" android:id="@+id/ApplicationMainSight" android:layout_toLeftOf="@+id/ApplicationMainEvent"></Button> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_width="fill_parent" android:text="@string/sights" android:id="@+id/ApplicationMainSight" android:layout_toLeftOf="@+id/ApplicationMainEvent"></Button> </LinearLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_weight="1" android:layout_width="fill_parent" android:text="@string/usergenerated" android:id="@+id/ApplicationMainUserGenerated"></Button> <Button android:layout_height="wrap_content" style="@style/CKMainButton" android:layout_weight="1" android:layout_width="fill_parent" android:text="@string/tours" android:id="@+id/ApplicationMainTour"></Button> </LinearLayout> </LinearLayout> It's looking like this: How can i acchieve the Layout to look like the image above?

• Debugging a working program on Mathematica 5 with Mathematica 7

  - by Neuschwanstein

  Hi everybody, I'm currently reading the Mathematica Guidebooks for Programming and I was trying to work out one of the very first program of the book. Basically, when I run the following program: Plot3D[{Re[Exp[1/(x + I y)]]}, {x, -0.02, 0.022}, {y, -0.04, 0.042}, PlotRange -> {-1, 8}, PlotPoints -> 120, Mesh -> False, ColorFunction -> Function[{x1, x2, x3}, Hue[Arg[Exp[1/(x1 + I x2)]]]]] either I get a 1/0 error and e^\infinity error or, if I lower the PlotPoints options to, say, 60, an overflow error. I have a working output though, but it's not what it's supposed to be. The hue seems to be diffusing off the left corner whereas it should be diffusing of the origin (as can be seen on the original output) Here is the original program which apparently runs on Mathematica 5 (Trott, Mathematica Guidebook for Programming): Off[Plot3D::gval]; Plot3D[{Re[Exp[1/(x + I y)]], Hue[Arg[Exp[1/(x + I y)]]]}, {x, -0.02, 0.022}, {y, -0.04, 0.042}, PlotRange -> {-1, 8}, PlotPoints -> 120, Mesh -> False] Off[Plot3D::gval]; However, ColorFunction used this way (first Plot3D argument) doesn't work and so I tried to simply adapt to its new way of using it. Well, thanks I guess!

• How to handle One View with multiple ViewModel and fire different Commands

  - by Naresh

  Hi All, I have senario in which one view and view has binding with multiple ViewModel. Eg. One View displaying Phone Detail and ViewModel as per bellow: Phone basic features- PhoneViewModel, Phone Price Detail- PhoneSubscriptionViewModel, Phone Accessories- PhoneAccessoryViewModel For general properties- PhoneDetailViewModel I have placed View's general properties to PhoneViewModel.Now senario is like this: By default View displays Phone Basic feaures which is bind with ObservationCollection of PhoneViewModel. My view have button - 'View Accessories', onclick of this button one popup screen- in my design I have display/hide Grid and bind it with ObservationCollection of PhoneAccessoryViewModel. Now problem begins- Accessory List also have button 'View Detail' onclick I have to open one popup screen, here also I had placed one Grid and Visible/Hide it. I have bind 'ViewAccessoryDetailCommand' command to 'View Detail' button. And on command execution one function fires and set property which Visible the Popup screen. Using such programming command fires, function calls but the property change not raises and so my view does not display popup. Summary: One View-- ViewModel1--Grid Bind view ViewModel2 --Grid Have Button and Onclick display new Grid which binded with ViewModel3-this Command fires but property not raises. I think there is some problem in my methodology, Please, give your suggetions.

• T SQL Rotate row into columns

• How do DP and CC change in Piet?

  - by Paul Butcher

  According to the specification, Black colour blocks and the edges of the program restrict program flow. If the Piet interpreter attempts to move into a black block or off an edge, it is stopped and the CC is toggled. The interpreter then attempts to move from its current block again. If it fails a second time, the DP is moved clockwise one step. These attempts are repeated, with the CC and DP being changed between alternate attempts. If after eight attempts the interpreter cannot leave its current colour block, there is no way out and the program terminates. Unless I'm reading it incorrectly, this is at odds with the behaviour of the Fibonacci sequence example here: http://www.dangermouse.net/esoteric/piet/fibbig1.gif (from: http://www.dangermouse.net/esoteric/piet/samples.html) Specifically, why does the DP turn left at (0,3) ((0,0) being (top, left)) when it hits the left edge? At this point, both DP and CC are LEFT, so, by my reading, the sequence should then be: Attempt (and fail) to leave the block by going off the edge at (0,4), Toggle CC to RIGHT, Attempt (and fail) to leave the block by going off the edge at (0,2). Rotate DP to UP, Attempt (and succeed) to leave the block at (1,2) by entering the white block at (1,1) The behaviour indicated by the trace seems to be that DP gets rotated all the way, leaving CC at LEFT. What have I misunderstood?

• iPhone SDK: PushViewController not working

  - by iPhone Developer

  I am trying to create a basic navigation application with a header and detail screen. My problem is the detail screen is not working. The code below is for the opening the detail view and placing it on the nav stack. My problem is the detail screen is not being pushed and I'm not sure why? I have verified the method below is firing. Any ptr or links to examples appreciated. //this opens up a detail view -(void) tableView:(UITableView *)tb didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"DETAIL VIEW....."); NSInteger index = [indexPath indexAtPosition:1]; Retailer *retailer = [self retailerAtIndex:index]; if(retailer) { NSLog(@"DETAIL VIEW helelelelekjekljklerj....."); Membership * newMem = [[Membership alloc] init]; [newMem setIssuerId:[retailer retailerId]]; MembershipViewController * mvc = [[MembershipViewController alloc] initWithNibName:nil bundle:nil]; [mvc setSubject:newMem]; RootAppDelegate *appDelegate = (RootAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate.landingRetailersNavController pushViewController:mvc animated:YES]; [mvc release]; [newMem release]; }

• AdMob ad in iPhone app makes App content disappear when "done" is pressed!

  - by nephilite

  Hello All, When I return from an adMob ad by hitting "done" the content of my app has disappeared ! All that remains is a background image I had attached directly to the main window. Oddly I can still hear the result of my touch events from my main screen (which is now gone). This may be related to the issue some people have had regarding a 20 pixel move involving the toolbar...I see something to that effect as the ad starts to overlay. I have admob in another app that is working fine, and I notice when the ad opens in that app the ad content fills the whole screen EXCEPT the top toolbar (it starts right under it). In the new app I'm working on right now this isn't the case. When the ad starts to open I see the tool bar vanish, then the add comes in and fills the entire screen (including the area where the tool bar was); then when I click done and the the ad goes away everything under it is gone as well. It may be worth noting that the App I had working was 2.x and the current app is 3.x (and thus using the admob 3.0 libraries). This is very odd and deal-breaking; I need help ASAP The relevant part of my view hierarchy is as follows: AppDelegate - ViewController - MainView (Ad is in here) There are also some other Views that are children of the ViewController and a UITabbar is also a subview of the ViewController (programmatically declared, not a UITabBar Controller). Any help you can offer would be extremely appreciate...I need to resolve this issue ASAP, release in two days! Thanks!!

• Why do I get completely different results when saving a BitmapSource to bmp, jpeg, and png in WPF

  - by DanM

  I wrote a little utility class that saves BitmapSource objects to image files. The image files can be either bmp, jpeg, or png. Here is the code: public class BitmapProcessor { public void SaveAsBmp(BitmapSource bitmapSource, string path) { Save(bitmapSource, path, new BmpBitmapEncoder()); } public void SaveAsJpg(BitmapSource bitmapSource, string path) { Save(bitmapSource, path, new JpegBitmapEncoder()); } public void SaveAsPng(BitmapSource bitmapSource, string path) { Save(bitmapSource, path, new PngBitmapEncoder()); } private void Save(BitmapSource bitmapSource, string path, BitmapEncoder encoder) { using (var stream = new FileStream(path, FileMode.Create)) { encoder.Frames.Add(BitmapFrame.Create(bitmapSource)); encoder.Save(stream); } } } Each of the three Save methods work, but I get unexpected results with bmp and jpeg. Png is the only format that produces an exact reproduction of what I see if I show the BitmapSource on screen using a WPF Image control. Here are the results: BMP - too dark JPEG - too saturated PNG - correct Why am I getting completely different results for different file types? I should note that the BitmapSource in my example uses an alpha value of 0.1 (which is why it appears very desaturated), but it should be possible to show the resulting colors in any image format. I know if I take a screen capture using something like HyperSnap, it will look correct regardless of what file type I save to. Here's a HyperSnap screen capture saved as a bmp: As you can see, this isn't a problem, so there's definitely something strange about WPF's image encoders. Do I have a setting wrong? Am I missing something?

• How i zoom perticular part of UIScrollView?

  - by Rajendra Bhole

  HI, I develop an application in which i want to implement the splash screen, on that splash screen i want to bind the scrollView and UIImage. My code as follow, -(void)splashAnimation{ window = [[UIWindow alloc] initWithFrame:CGRectMake(0, 0, 320, 420)]; //scrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; scrollView = [[UIScrollView alloc] initWithFrame:[window bounds]]; scrollView.pagingEnabled = NO; scrollView.bounces = NO; UIImage *image = [UIImage imageNamed:@"splash.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; imageView.userInteractionEnabled = NO; [scrollView addSubview:imageView]; [scrollView setDelegate:self]; //[scrollView release]; } - (void)applicationDidFinishLaunching:(UIApplication *)application { [self splashAnimation]; [self initControllers]; [window addSubview:[mainTabBarController view]]; [window makeKeyAndVisible]; } On my given code the one blank window comes up and stay on. I want to on that blank screen bind my splash.png. *The Above problem is solved* My current code is scrollView.pagingEnabled = NO; scrollView.bounces = NO; UIImage *image = [UIImage imageNamed:@"splash.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; imageView.userInteractionEnabled = NO; [scrollView addSubview:imageView]; scrollView.maximumZoomScale = 4.0f; scrollView.minimumZoomScale = 1.0f; CGRect rect = CGRectMake(119, 42, 208, 166); [scrollView zoomToRect:rect animated:YES]; [scrollView setDelegate:self]; [window addSubview:scrollView]; [window makeKeyAndVisible]; i want to zoom the particular part of scrollView.
