• Don't see Clean solution option in Visual Studio

  - by user102533

  For one of the solutions, I don't see the Clean Solution option neither in the context menu when I right click on the solution name in the Solution Explorer nor in the Build menu. When I make any changes to the project and debug, VS never hits the break point and I get the "The breakpoint will not currently be hit. The source code is different from the original version." message. My understanding is that I need to clean the solution. For other solutions, I do see the Clean solution and I don't have the same issue.

• Splitting a string according to a delimiter when elements in the string can contain the delimiter

  - by Vivin Paliath

  I have a string that looks like this: "#Text() #SomeMoreText() #TextThatContainsDelimiter(#blah) #SomethingElse()" I'd like to get back [#Text(), #SomeMoreText(), #TextThatContainsDelimiter(#blah), #SomethingElse()] One way I thought about doing this was to require that the # to be escaped into \#, which makes the input string: "#Text() #SomeMoreText() #TextThatContainsDelimiter(\#blah) #SomethingElse()" I can then split it using /[^\\]#/ which gives me: [#Text(), SomeMoreText, TextThatContainsDelimiter(\#blah), SomethingElse()] The first element will contain # but I can strip it out. However, is there a cleaner way to do this without having to escape the #, and which ensures that the first element will not contain a #? Basically I'd like it to split by # only if the # is not enclosed by parentheses. My hunch is that since the # is context-sensitive and and regular expressions are only suited for context-free strings, this may not be the right tool. If so, would I have to write a grammar for this and roll my own parser/lexer?

• Url encode and routing?

  - by Curtis White

  I'm using custom routing in a web forms context. I have some titles (part of my custom route) that have say a question mark character. When I URL encode this text ("Question?") and then pass into my route, I get an HTTP ERROR CODE 400. Apparently, the URL encoded text is somehow confusing the routing manager. Can someone provide context and explanation for this? Beyond that, I'm thinking I don't need to URL encode these route data but merely strip out the problem characters. Are there any security risks to not using URL decode/encode? And what are the problem characters? A list would be useful. Thanks!

• In Ruby are there any related applications of the syntax: class << self ... end

  - by pez_dispenser

  class << self attr_accessor :n, :totalX, :totalY end The syntax above is used for defining class instance variables. But when I think about what syntax implies, it doesn't make any sense to me, so I'm wondering if this type of syntax is used for any other types of definitions. My point of confusion here is this: class << self The append operator normally means "add what's on the right to the object on the left". But in the context of this block, how does that add up to "put the contents of this block into the definition of the class instance rather than the instance"? For the same reason I'm confused as to why in one context class << self can define class instance variables while in another it seems to create class variables such as here: class Point # Instance methods go here class << self # Class methods go here end end

• accessing embedded object with jquery not working in firefox 3.6

  - by taber

  Hi, this code in my plugin used to work just fine: jQuery('#embedded_obj', context).get(0).getVersion(); and in html... <object id="embedded_obj" type="application/x-versionchecker-1.0.0.1"</object Basically trying to get the properties from an embedded object. But it looks like get(0) is returning an html object instead of the actual embedded object. For example, if I do: var launcher = jQuery('#embedded_obj', context).get(0); for(prop in launcher){ alert(prop + ': ' + launcher[prop]); } ... it alerts things like "getElementByNode," "scrollWidth," "clientLeft," "clientTop" etc. Again this worked before Firefox 3.6. Has anyone else seen this or have any ideas/suggestions? Thanks!

• Does Safari have a timeout issue?

  - by woodysapsucker

  I have a website that works fine in Firefox and IE but never finishes loading in Safari 4.0.4. The live website loads a menu then loads a Google map. Using Safari, the Google map never loads. I have a test website on the same server that uses the exact same code for loading a Google map and Safari can load the map (this is the one that won't load on my live web). This test website does not have the menu - only the Google map. In both cases (live and test) the main web page calls a loadmap.js file. I've been pulling everything apart to try to identify why Safari won't finish loading. Has anyone run across any problems/solutions with Safari that may help me find a resolution to this problem?

• How2 display Image from DB in datagrid?

  - by Saverio Tedeschi

  Hope it's not yet been answered, but I've googled for quite a long time, and I've not been able to get it working. In brief, I've a SL4 page with a DataGrid filled accordingly to parameters passed from the previous page, so I fill the context in code, with a "RIA" query (w/parameters as well). So far, so good. I get the XAML declared columns as expected but the Photo templated column, which holds just an image control. I think I can use the LoadingRow event, but can some1 give me some code on how to get my goal (image is in in the context from DB)? Thanks in advance

• How to call a new thread from button click

  - by Lynnooi

  Hi, I'm trying to call a thread on a button click (btn_more) but i cant get it right. The thread is to get some data and update the images. The problem i have is if i only update 4 or 5 images then it works fine. But if i load more than 5 images i will get a force close. At times when the internet is slow I will face the same problem too. Can please help me to solve this problem or provide me some guidance? Here is the error i got from LogCat: 04-19 18:51:44.907: ERROR/AndroidRuntime(1034): Uncaught handler: thread main exiting due to uncaught exception 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): java.lang.NullPointerException 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at mobile9.android.gallery.GalleryWallpapers.setWallpaperThumb(GalleryWallpapers.java:383) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at mobile9.android.gallery.GalleryWallpapers.access$4(GalleryWallpapers.java:320) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at mobile9.android.gallery.GalleryWallpapers$1.handleMessage(GalleryWallpapers.java:266) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at android.os.Handler.dispatchMessage(Handler.java:99) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at android.os.Looper.loop(Looper.java:123) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at android.app.ActivityThread.main(ActivityThread.java:4310) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at java.lang.reflect.Method.invokeNative(Native Method) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at java.lang.reflect.Method.invoke(Method.java:521) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 04-19 18:51:44.927: ERROR/AndroidRuntime(1034): at dalvik.system.NativeStart.main(Native Method) My Code: public class GalleryWallpapers extends Activity implements Runnable { public static String MODEL = android.os.Build.MODEL ;

• Cannot combine commits using TortoiseGit

  - by JC

  I have two branches with several commits each. On one branch, I can go to the log, select two commits, and TortoiseGit shows "combine to one commit" in the context menu. On the other branch this option does not show in the context menu. Both sequence of commits is very similar; add file then modify it, so there is no difference really between the branches. What factors would cause this "combine to one commit" to not be available? I'm wondering if I should just switch to the command line.

• Cocoa NSStatusBar Global HotKey

  - by Craig

  I have created an NSStatusBar cocoa application which sits in the system status bar. I want to assign a hotkey so that when pressed it toggles my applications and show the menu. Is this possible?, In my searching and experimenting I have found a few different ways of assigning global hot keys that can be pressed when your application is in the background but I can't find any way to problematically make the menu show. Is this possible?, If anyone thinks a way of assigning a global hotkey is best please post it. Thanks. One of the hotkey tutorials I found was on http://dbachrach.com/blog/2005/11/program-global-hotkeys-in-cocoa-easily/ for anyone interested.

• LabVIEW: converting numeric array to string array

  - by JaysonFix

  Using LabVIEW 2009, I have a VI that outputs an array of U64 integers. I'd like the user to be able to perform discrete selection from among the elements of this array. I'm thinking of accomplishing this by programmatically populating a Menu Ring (as shown at http://digital.ni.com/public.nsf/allkb/FB0409491FAB16FA86256D08004FCE7E). However, I apparently need to convert my array of U64 ints to an array of strings, as it is an array of strings that is used to populate the Menu Ring. My question: how can I convert the array of U64 ints to an array of strings?

• Insert new relationship data in core data

  - by michael

  Hoping someone can shed some light on what I might be doing wrong here. Trying to add an "event" to a list of events, represented by a one to many (inverse) relationship: MyEvents <--- Event This is the code: MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSLog(@"MYEVENTS: %@", myEvents); NSLog(@"EVENT: %@", event); [myEvents addEventObject:event]; My context is fine, and both the myEvents and event print perfectly valid information. When I try to add the event that I have (which is passed into this view controller, having been retrieved from core data previously) with this code [myEvents addEventObject:event]; It falls over with *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance MyEvents and Event are just the default generated code. MyEvents contains only the relationship to event. Thanks.

• Error releasing Grails plugin

  Hi, I checked out the trunk of my plugin from the Grails svn repo, made some changes, incremented the version number to 0.2.1, then ran release-plugin. It failed with the error shown below: Checking in plugin zip... Updating from SVN... Updated to revision 61343. Committing local, please wait...

• Drawing a texture with an alpha channel doesn't work -- draws black

  - by DevDevDev

  I am modifying GLPaint to use a different background, so in this case it is white. Anyway the existing stamp they are using assumes the background is black, so I made a new background with an alpha channel. When I draw on the canvas it is still black, what gives? When I actually draw, I just bind the texture and it works. Something is wrong in this initialization. Here is the photo - (id)initWithCoder:(NSCoder*)coder { CGImageRef brushImage; CGContextRef brushContext; GLubyte *brushData; size_t width, height; if (self = [super initWithCoder:coder]) { CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = YES; // In this application, we want to retain the EAGLDrawable contents after a call to presentRenderbuffer. eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES1]; if (!context || ![EAGLContext setCurrentContext:context]) { [self release]; return nil; } // Create a texture from an image // First create a UIImage object from the data in a image file, and then extract the Core Graphics image brushImage = [UIImage imageNamed:@"test.png"].CGImage; // Get the width and height of the image width = CGImageGetWidth(brushImage); height = CGImageGetHeight(brushImage); // Texture dimensions must be a power of 2. If you write an application that allows users to supply an image, // you'll want to add code that checks the dimensions and takes appropriate action if they are not a power of 2. // Make sure the image exists if(brushImage) { brushData = (GLubyte *) calloc(width * height * 4, sizeof(GLubyte)); brushContext = CGBitmapContextCreate(brushData, width, width, 8, width * 4, CGImageGetColorSpace(brushImage), kCGImageAlphaPremultipliedLast); CGContextDrawImage(brushContext, CGRectMake(0.0, 0.0, (CGFloat)width, (CGFloat)height), brushImage); CGContextRelease(brushContext); glGenTextures(1, &brushTexture); glBindTexture(GL_TEXTURE_2D, brushTexture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, brushData); free(brushData); } //Set up OpenGL states glMatrixMode(GL_PROJECTION); CGRect frame = self.bounds; glOrthof(0, frame.size.width, 0, frame.size.height, -1, 1); glViewport(0, 0, frame.size.width, frame.size.height); glMatrixMode(GL_MODELVIEW); glDisable(GL_DITHER); glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_DST_ALPHA); glEnable(GL_POINT_SPRITE_OES); glTexEnvf(GL_POINT_SPRITE_OES, GL_COORD_REPLACE_OES, GL_TRUE); glPointSize(width / kBrushScale); } return self; }

• ExtJS 4.1: FocusManager.enable prevents stopping click event

  - by jacob

  If FocusManager is enabled, then Menu item href click handlers can not be stopped. This causes the native click handler to complete and navigate the location hash to '#'. If FocusManager is not enabled, it does not change the hash. I tried overriding Ext.menu.Item to call evt.stopEvent if href is null. However, it looks like the EventManager.createListenerWrap() method totally hides the actual browser event and replaces it with an EventObject focus event. What's the correct solution here? Thanks.

• How to figure out which jars are needed?

  - by Ari

  How can I systematically determine which jars I'll need, and thus should include in my pom.xml file (I'm using maven as my project management tool)? When learning spring, to keep things simple, added all the jars (even the ones I never used) to the classpath. Right now for the most part, I'm guessing which jars to include. For example, I know in my spring configuration file, I have: <tx:annotation-driven /> <context:annotation-config /> <aop:aspectj-autoproxy /> So, I guess I'll need: spring-context-x.x.x.jar, spring-tx-x.x.x.jar, spring-aop-x.x.x.jar Thanks.

• differences between using wmode="transparent", "opaque", "window" for an embedded object on webpage

  - by Jian Lin

  when embedding a Flash object with the <object and <embed tag, there is an attribute called "wmode". It seems that most of the time, wmode="transparent" is the same as wmode="opaque" as the Flash doesn't actually have any transparent color so that the bottom HTML element is to be shown. As a result, "opaque" should be faster than "transparent" since it require less processing for transparency, yet most of the time i see Flash object embedded with "transparent" instead of "opaque". "opaque" is needed so that other HTML element won't be covered up by the Flash object. (such as a menu item that pops up an extra sub-menu won't be covered up by the Flash object). By the way, is there formal documentation for wmode's "opaque", "transparent", and "window"? I was only able to find blogs that describe it but not the formal documentation. thanks.

• Location of New Window after old window closed

  - by John Brayton

  I have an app that allows multiple windows. I have a strange bug where, if I repeatedly open and close windows, new windows are positioned lower and lower on the screen. I would expect this if I were keeping the windows open, but it seems that the OS X window tiling mechanism is unaware of when my windows are closing. Potentially relevant notes: I am using garbage collection. This is not a document-based app. When I close a window, the corresponding menu item is removed from the "Window" menu. Any hints as to what I might be doing wrong would be appreciated. Thanks!
