• Multithreaded UI desktop application issues

  - by igor

  I am involved into development a rich UI project: desktop windows application. Application uses asynchronous invocations and in its turn it should be ready to process external messages (events). The problem is clear: at first time it was built as a simple prototype and it was not stress tested and all was fine. Then application was grown: the number of calls to server and number of events from server are high and performance is low. What is more users noticed that sometimes performance is extremal low. Asynchronous invocations based on thread pool (BeginInvoke, EndInvoke), external events are going from WCF service (.NET 3.5). My goal is synchronization of all tasks and putting priorities to every executions in desktop application. My question is: is there any practice how to reach my goal: patterns, task priority list, others? What should I do at first, second and next times? Thanks

• Formatting minified jQuery, JavaScript using the Internet Explorer 9 Developer Toolbar

  - by Harish Ranganathan

  Much has been talked about the F12 developer toolbar in IE and the support it provides for web developers.  Starting IE8, the Developer Toolbar is a menu item that helps you view the page source, scripts, profiling and many other details of the rendered page.  It even allows script debugging from within and that makes it a truly powerful web developer tool bar. With IE9, the developer toolbar got even better with the Networking Tab that allows you to inspect the traffic/time taken and drill down into the Request/Response headers and other specifics. The script tab allows you to view the scripts used in the page. One of the challenges of working with JavaScript / jQuery when they are minified, is that, it becomes really hard to read.  Minified JavaScript is a compression technique and also a best practice for delivering faster web pages.  However, when you would like to debug, minified JavaScript files become very hard since they aren't properly formatted.  Take the case of the above sample, which is a basic MVC 3 Web Application.  It uses the minified jQuery and modernizr files. Once we select the above scripts, the script source looks as follows:- But with the “Format JavaScript” option in the Configuration icon, Once you click on the “Format JavaScript”, you can see the formatted JavaScript as per screen below:- This makes the script readable and also easy for debugging.  Cheers !!!

• JOGL hardware based shadow mapping - computing the texture matrix

  - by axel22

  I am implementing hardware shadow mapping as described here. I've rendered the scene successfully from the light POV, and loaded the depth buffer of the scene into a texture. This texture has correctly been loaded - I check this by rendering a small thumbnail, as you can see in the screenshot below, upper left corner. The depth of the scene appears to be correct - objects further away are darker, and that are closer to the light are lighter. However, I run into trouble while rendering the scene from the camera's point of view using the depth texture - the texture on the polygons in the scene is rendered in a weird, nondeterministic fashion, as shown in the screenshot. I believe I am making an error while computing the texture transformation matrix, but I am unsure where exactly. Since I have no matrix utilities in JOGL other then the gl[Load|Mult]Matrix procedures, I multiply the matrices using them, like this: void calcTextureMatrix() { glPushMatrix(); glLoadIdentity(); glLoadMatrixf(biasmatrix, 0); glMultMatrixf(lightprojmatrix, 0); glMultMatrixf(lightviewmatrix, 0); glGetFloatv(GL_MODELVIEW_MATRIX, shadowtexmatrix, 0); glPopMatrix(); } I obtained these matrices by using the glOrtho and gluLookAt procedures: glLoadIdentity() val wdt = width / 45 val hgt = height / 45 glOrtho(wdt, -wdt, -hgt, hgt, -45.0, 45.0) glGetFloatv(GL_MODELVIEW_MATRIX, lightprojmatrix, 0) glLoadIdentity() glu.gluLookAt( xlook + lightpos._1, ylook + lightpos._2, lightpos._3, xlook, ylook, 0.0f, 0.f, 0.f, 1.0f) glGetFloatv(GL_MODELVIEW_MATRIX, lightviewmatrix, 0) My bias matrix is: float[] biasmatrix = new float[16] { 0.5f, 0.f, 0.f, 0.f, 0.f, 0.5f, 0.f, 0.f, 0.f, 0.f, 0.5f, 0.f, 0.5f, 0.5f, 0.5f, 1.f } After applying the camera projection and view matrices, I do: glTexGeni(GL_S, GL_TEXTURE_GEN_MODE, GL_EYE_LINEAR) glTexGenfv(GL_S, GL_EYE_PLANE, shadowtexmatrix, 0) glEnable(GL_TEXTURE_GEN_S) for each component. Does anybody know why the texture is not being rendered correctly? Thank you.

• Custom Gesture in cocos2d

  - by Lewis

  I've found a little tutorial that would be useful for my game: http://blog.mellenthin.de/archives/2012/02/13/an-one-finger-rotation-gesture-recognizer/ But I can't work out how to convert that gesture to work with cocos2d, I have found examples of pre made gestures in cocos2d, but no custom ones, is it possible? EDIT STILL HAVING PROBLEMS WITH THIS: I've added the code from Sentinel below (from SO), the Gesture and RotateGesture have both been added to my solution and are compiling. Although In the rotation class now I only see selectors, how do I set those up? As the custom gesture found in that project above looks like: header file for custom gesture: #import <Foundation/Foundation.h> #import <UIKit/UIGestureRecognizerSubclass.h> @protocol OneFingerRotationGestureRecognizerDelegate <NSObject> @optional - (void) rotation: (CGFloat) angle; - (void) finalAngle: (CGFloat) angle; @end @interface OneFingerRotationGestureRecognizer : UIGestureRecognizer { CGPoint midPoint; CGFloat innerRadius; CGFloat outerRadius; CGFloat cumulatedAngle; id <OneFingerRotationGestureRecognizerDelegate> target; } - (id) initWithMidPoint: (CGPoint) midPoint innerRadius: (CGFloat) innerRadius outerRadius: (CGFloat) outerRadius target: (id) target; - (void)reset; - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event; - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event; - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event; - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event; @end .m for custom gesture file: #include <math.h> #import "OneFingerRotationGestureRecognizer.h" @implementation OneFingerRotationGestureRecognizer // private helper functions CGFloat distanceBetweenPoints(CGPoint point1, CGPoint point2); CGFloat angleBetweenLinesInDegrees(CGPoint beginLineA, CGPoint endLineA, CGPoint beginLineB, CGPoint endLineB); - (id) initWithMidPoint: (CGPoint) _midPoint innerRadius: (CGFloat) _innerRadius outerRadius: (CGFloat) _outerRadius target: (id <OneFingerRotationGestureRecognizerDelegate>) _target { if ((self = [super initWithTarget: _target action: nil])) { midPoint = _midPoint; innerRadius = _innerRadius; outerRadius = _outerRadius; target = _target; } return self; } /** Calculates the distance between point1 and point 2. */ CGFloat distanceBetweenPoints(CGPoint point1, CGPoint point2) { CGFloat dx = point1.x - point2.x; CGFloat dy = point1.y - point2.y; return sqrt(dx*dx + dy*dy); } CGFloat angleBetweenLinesInDegrees(CGPoint beginLineA, CGPoint endLineA, CGPoint beginLineB, CGPoint endLineB) { CGFloat a = endLineA.x - beginLineA.x; CGFloat b = endLineA.y - beginLineA.y; CGFloat c = endLineB.x - beginLineB.x; CGFloat d = endLineB.y - beginLineB.y; CGFloat atanA = atan2(a, b); CGFloat atanB = atan2(c, d); // convert radiants to degrees return (atanA - atanB) * 180 / M_PI; } #pragma mark - UIGestureRecognizer implementation - (void)reset { [super reset]; cumulatedAngle = 0; } - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesBegan:touches withEvent:event]; if ([touches count] != 1) { self.state = UIGestureRecognizerStateFailed; return; } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; if (self.state == UIGestureRecognizerStateFailed) return; CGPoint nowPoint = [[touches anyObject] locationInView: self.view]; CGPoint prevPoint = [[touches anyObject] previousLocationInView: self.view]; // make sure the new point is within the area CGFloat distance = distanceBetweenPoints(midPoint, nowPoint); if ( innerRadius <= distance && distance <= outerRadius) { // calculate rotation angle between two points CGFloat angle = angleBetweenLinesInDegrees(midPoint, prevPoint, midPoint, nowPoint); // fix value, if the 12 o'clock position is between prevPoint and nowPoint if (angle > 180) { angle -= 360; } else if (angle < -180) { angle += 360; } // sum up single steps cumulatedAngle += angle; // call delegate if ([target respondsToSelector: @selector(rotation:)]) { [target rotation:angle]; } } else { // finger moved outside the area self.state = UIGestureRecognizerStateFailed; } } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesEnded:touches withEvent:event]; if (self.state == UIGestureRecognizerStatePossible) { self.state = UIGestureRecognizerStateRecognized; if ([target respondsToSelector: @selector(finalAngle:)]) { [target finalAngle:cumulatedAngle]; } } else { self.state = UIGestureRecognizerStateFailed; } cumulatedAngle = 0; } - (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesCancelled:touches withEvent:event]; self.state = UIGestureRecognizerStateFailed; cumulatedAngle = 0; } @end Then its initialised like this: // calculate center and radius of the control CGPoint midPoint = CGPointMake(image.frame.origin.x + image.frame.size.width / 2, image.frame.origin.y + image.frame.size.height / 2); CGFloat outRadius = image.frame.size.width / 2; // outRadius / 3 is arbitrary, just choose something >> 0 to avoid strange // effects when touching the control near of it's center gestureRecognizer = [[OneFingerRotationGestureRecognizer alloc] initWithMidPoint: midPoint innerRadius: outRadius / 3 outerRadius: outRadius target: self]; [self.view addGestureRecognizer: gestureRecognizer]; The selector below is also in the same file where the initialisation of the gestureRecogonizer: - (void) rotation: (CGFloat) angle { // calculate rotation angle imageAngle += angle; if (imageAngle > 360) imageAngle -= 360; else if (imageAngle < -360) imageAngle += 360; // rotate image and update text field image.transform = CGAffineTransformMakeRotation(imageAngle * M_PI / 180); [self updateTextDisplay]; } I can't seem to get this working in the RotateGesture class can anyone help me please I've been stuck on this for days now. SECOND EDIT: Here is the users code from SO that was suggested to me: Here is projec on GitHub: SFGestureRecognizers It uses builded in iOS UIGestureRecognizer, and don't needs to be integrated into cocos2d sources. Using it, You can make any gestures, just like you could, if you whould work with UIGestureRecognizer. For example: I made a base class Gesture, and subclassed it for any new gesture: //Gesture.h @interface Gesture : NSObject <UIGestureRecognizerDelegate> { UIGestureRecognizer *gestureRecognizer; id delegate; SEL preSolveSelector; SEL possibleSelector; SEL beganSelector; SEL changedSelector; SEL endedSelector; SEL cancelledSelector; SEL failedSelector; BOOL preSolveAvailable; CCNode *owner; } - (id)init; - (void)addGestureRecognizerToNode:(CCNode*)node; - (void)removeGestureRecognizerFromNode:(CCNode*)node; -(void)recognizer:(UIGestureRecognizer*)recognizer; @end //Gesture.m #import "Gesture.h" @implementation Gesture - (id)init { if (!(self = [super init])) return self; preSolveAvailable = YES; return self; } - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer { return YES; } - (BOOL)gestureRecognizer:(UIGestureRecognizer *)recognizer shouldReceiveTouch:(UITouch *)touch { //! For swipe gesture recognizer we want it to be executed only if it occurs on the main layer, not any of the subnodes ( main layer is higher in hierarchy than children so it will be receiving touch by default ) if ([recognizer class] == [UISwipeGestureRecognizer class]) { CGPoint pt = [touch locationInView:touch.view]; pt = [[CCDirector sharedDirector] convertToGL:pt]; for (CCNode *child in owner.children) { if ([child isNodeInTreeTouched:pt]) { return NO; } } } return YES; } - (void)addGestureRecognizerToNode:(CCNode*)node { [node addGestureRecognizer:gestureRecognizer]; owner = node; } - (void)removeGestureRecognizerFromNode:(CCNode*)node { [node removeGestureRecognizer:gestureRecognizer]; } #pragma mark - Private methods -(void)recognizer:(UIGestureRecognizer*)recognizer { CCNode *node = recognizer.node; if (preSolveSelector && preSolveAvailable) { preSolveAvailable = NO; [delegate performSelector:preSolveSelector withObject:recognizer withObject:node]; } UIGestureRecognizerState state = [recognizer state]; if (state == UIGestureRecognizerStatePossible && possibleSelector) { [delegate performSelector:possibleSelector withObject:recognizer withObject:node]; } else if (state == UIGestureRecognizerStateBegan && beganSelector) [delegate performSelector:beganSelector withObject:recognizer withObject:node]; else if (state == UIGestureRecognizerStateChanged && changedSelector) [delegate performSelector:changedSelector withObject:recognizer withObject:node]; else if (state == UIGestureRecognizerStateEnded && endedSelector) { preSolveAvailable = YES; [delegate performSelector:endedSelector withObject:recognizer withObject:node]; } else if (state == UIGestureRecognizerStateCancelled && cancelledSelector) { preSolveAvailable = YES; [delegate performSelector:cancelledSelector withObject:recognizer withObject:node]; } else if (state == UIGestureRecognizerStateFailed && failedSelector) { preSolveAvailable = YES; [delegate performSelector:failedSelector withObject:recognizer withObject:node]; } } @end Subclass example: //RotateGesture.h #import "Gesture.h" @interface RotateGesture : Gesture - (id)initWithTarget:(id)target preSolveSelector:(SEL)preSolve possibleSelector:(SEL)possible beganSelector:(SEL)began changedSelector:(SEL)changed endedSelector:(SEL)ended cancelledSelector:(SEL)cancelled failedSelector:(SEL)failed; @end //RotateGesture.m #import "RotateGesture.h" @implementation RotateGesture - (id)initWithTarget:(id)target preSolveSelector:(SEL)preSolve possibleSelector:(SEL)possible beganSelector:(SEL)began changedSelector:(SEL)changed endedSelector:(SEL)ended cancelledSelector:(SEL)cancelled failedSelector:(SEL)failed { if (!(self = [super init])) return self; preSolveSelector = preSolve; delegate = target; possibleSelector = possible; beganSelector = began; changedSelector = changed; endedSelector = ended; cancelledSelector = cancelled; failedSelector = failed; gestureRecognizer = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(recognizer:)]; gestureRecognizer.delegate = self; return self; } @end Use example: - (void)addRotateGesture { RotateGesture *rotateRecognizer = [[RotateGesture alloc] initWithTarget:self preSolveSelector:@selector(rotateGesturePreSolveWithRecognizer:node:) possibleSelector:nil beganSelector:@selector(rotateGestureStateBeganWithRecognizer:node:) changedSelector:@selector(rotateGestureStateChangedWithRecognizer:node:) endedSelector:@selector(rotateGestureStateEndedWithRecognizer:node:) cancelledSelector:@selector(rotateGestureStateCancelledWithRecognizer:node:) failedSelector:@selector(rotateGestureStateFailedWithRecognizer:node:)]; [rotateRecognizer addGestureRecognizerToNode:movableAreaSprite]; } I dont understand how to implement the custom gesture code at the start of this post into the rotateGesture class which is a subclass of the gesture class written by the SO user. Any ideas please? When I get 6 more rep I'll add a bounty to this.

• Purple Screen then Black Screen while Booting from CD or Windows Install

  - by Tyler

  Whenever I try to run Ubuntu from my internal CD drive, I see this screen minus the Ubuntu Text: Then the screen goes black, not even the internal light stays on. Sometimes it restarts itself, other times the black screen is indefinite until I restart the laptop myself. I'm on an HP Quad-Core AMD A8-3500M APU with 8 GB RAM and a Radeon AMD 6620g Discrete-Graphics Card. (HP dv6-6145dx) This is my first time using Linux, I am not too technically-inclined so any simplification would be welcomed. I am good at following technical instructions though which is how I was able to partition my hard drive and change the boot order to allow the internal CD drive first. Thanks in advance!

• Multithreded UI desktop application issues

  - by igor

  I am involved into development a rich UI project: desktop windows application. Application uses asynchronous invocations and in its turn it should be ready to process external messages (events). The problem is clear: at first time it was built as a simple prototype and it was not stress tested and all was fine. Then application was grown: the number of calls to server and number of events from server are high and performance is low. What is more users noticed that sometimes performance is extremal low. Asynchronous invocations based on thread pool (BeginInvoke, EndInvoke), external events are going from WCF service (.NET 3.5). My goal is synchronization of all tasks and putting priorities to every executions in desktop application. My question is: is there any practice how to reach my goal: patterns, task priority list, others? What should I do at first, second and next times? Thanks

• Quaternion Camera

  - by Alex_Hyzer_Kenoyer

  Can someone help me figure out how to use a Quaternion with the PerspectiveCamera in libGDX or in general? I am trying to rotate my camera around a sphere that is being drawn at (0,0,0). I am not sure how to go about setting up the quaternion correctly, manipulating it, and then applying it to the camera. Edit: Here is what I have tried to do so far. // This is how I set it up Quaternion orientation = new Quaternion(); orientation.setFromAxis(Vector3.Y, 45); // This is how I am trying to update the rotations public void rotateX(float amount) { Quaternion temp = new Quaternion(); temp.set(Vector3.X, amount); orientation.mul(temp); } public void rotateY(float amount) { Quaternion temp = new Quaternion(); temp.set(Vector3.Y, amount); orientation.mul(temp); } public void updateCamera() { // This is where I am unsure how to apply the rotations to the camera // I think I should update the view and projection matrices? camera.view.mul(orientation); ... }

  - by user36385

  Im making a game in XNA 4 and this is the first time I'm using the Content loader to initialize a simple class with a XML file, but no matter how many guide I follow, or how simple or complicated is my XML File the ContentManager cant find the file; the Debug keep telling me: "A first chance exception of type 'Microsoft.Xna.Framework.Content.ContentLoadException' occurred in Microsoft.Xna.Framework.dll". I'm really confuse because I can load SpriteFonts and Texture2D without a problem ... I create the following XML (the most basic Xna XML): <?xml version="1.0" encoding="utf-8" ?> <XnaContent> <Asset Type="System.String">Hello</Asset> </XnaContent> and I try to load it in the LoadContent method in my main class like this: System.String hello = Content.Load<System.String>("NewXmlFile"); There is something I'm doing wrong?

• Input handling between game loops

  - by user48023

  This may be obvious and trivial for you but as I am a newbie in programming I come with a specific question. I have three loops in my game engine which are input-loop, update-loop and render-loop. Update-loop is set to 10 ticks per second with a fixed timestep, render-loop is capped at around 60 fps and the input-loop runs as fast as possible. I am using one of the Javascript frameworks which provide such things but it doesn't really matter. Let's say I am rendering a tile map and the view of which elements are rendered depends on camera-like movement variables which are modified during key pressing. This is only about camera/viewport and rendering, no game physics involved here. And now, how can I handle input events among these loops to keep consistent engine reaction? Am I supposed to read the current variable modified with input and do some needed calculations in a update-loop and share the result so it could be interpolated in a render-loop? Or read the input effect directly inside the render-loop and put needed calculations inside? I thought interpreting user input inside an update-loop with a low tick rate would be inaccurate and kind of unresponsive while rendering with interpolation in the final view. How it is done properly in games overall?

• Learning PostgreSql: old versions of rows are stored right in the table

  - by Alexander Kuznetsov

  PostgreSql features multi-version concurrency control aka MVCC. To implement MVCC, old versions of rows are stored right in the same table, and this is very different from what SQL Server does, and it leads to some very interesting consequences. Let us play with this thing a little bit, but first we need to set up some test data. Setting up. First of all, let us create a numbers table. Any production database must have it anyway: CREATE TABLE Numbers ( i INTEGER ); INSERT INTO Numbers ( i ) VALUES...(read more)

• Eclipse Helios on OS X Snow Leopard crashes frequently when editing certain PHP files

  - by William

  I use Eclipse Helios (Eclipse Platform: 3.6.0.I20100608-0911, Eclipse IDE for PHP Developers: 1.3.0.20100617-0520) all the time on OS X (Snow Leopard), and it seems I only run into trouble whenever I'm editing a PHP file that's part of the WordPress blogging framework. When I move my cursor to a variable or function name, that often triggers the beach ball of death. I suspect Eclipse is trying to look up that variable/function and for some reason that causes an endless loop. Sometimes it's not just variables or functions. Just today I was trying to replace all occurrences of a quoted string. Every time I clicked "Replace All", the program would freeze immediately after the string was replaced and the text cursor was moved to the replaced position. I think the moving of the text cursor is important, because I got the same result when I searched for the string (thus moving the cursor), but NOT when I searched for a nonexistent string. I tried disabling everything in my preferences related to marked occurrences, hovering, code assistance, etc. Nothing helps. I use Eclipse for all my projects, and I find that it's only WordPress projects where this happens. Here's my eclipse.ini file: -startup ../../../plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.1.0.v20100503 -product org.eclipse.epp.package.php.product --launcher.defaultAction openFile -showsplash org.eclipse.platform --launcher.XXMaxPermSize 512m --launcher.defaultAction openFile -vmargs -Dosgi.requiredJavaVersion=1.5 -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -XX:PermSize=128m -XX:MaxPermSize=128m -XX:MaxGCPauseMillis=10 -XX:MaxHeapFreeRatio=70 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:CompileThreshold=5 -Xms128m -Xmx512m -Xss2m -Xdock:icon=../Resources/Eclipse.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -framework ../../../plugins/org.eclipse.osgi.services_3.2.100.v20100503.jar I have 4GB of RAM, so I don't know if the problem is I'm underutilizing my resources.

This value will be overwritten using the values from the preferences I did some experimenting with the particular script that's giving me trouble. It's a hybrid of HTML and PHP, so Eclipse has to do both HTML and PHP validation. I wondered if the HTML validation had something to do with it, so I created a new file, copied the contents over, and messed with the doctype element. I found that if I replaced the well-formed XHTML 1.0 Strict doctype element with a generic doctype (as such: <!DOCTYPE html>), then I did not crash the program just by moving the cursor around. I set all HTML validation rules to "Ignore", but it still didn't solve my problems. For now, I'm just going to echo the doctype using PHP instead of entering it literally. That seems to prevent crashes. I notice that when I move the cursor around the document, Eclipse displays the "xpath" to my current location at the bottom of the screen. Sometimes there's a delay while it figures out my current path. Perhaps when it's validating against the Strict doctype, it has problems quickly calculating the xpath as I move the cursor around? Maybe it has a stack overflow that causes it to crash.

• MSSQL: Copying data from one database to another

  - by DigiMortal

  I have database that has data imported from another server using import and export wizard of SQL Server Management Studio. There is also empty database with same tables but it also has primary keys, foreign keys and indexes. How to get data from first database to another? Here is the description of my crusade. And believe me – it is not nice one. Bugs in import and export wizard There is some awful bugs in import and export wizard that makes data imports and exports possible only on very limited manner: wizard is not able to analyze foreign keys, wizard wants to create tables always, whatever you say in settings. The result is faulty and useless package. Now let’s go step by step and make things work in our scenario. Database There are two databases. Let’s name them like this: PLAIN – contains data imported from remote server (no indexes, no keys, no nothing, just plain dumb data) CORRECT – empty database with same structure as remote database (indexes, keys and everything else but no data) Our goal is to get data from PLAIN to CORRECT. 1. Create import and export package In this point we will create faulty SSIS package using SQL Server Management Studio. Run import and export wizard and let it create SSIS package that reads data from CORRECT and writes it to, let’s say, CORRECT-2. Make sure you enable identity insert. Make sure there are no views selected. Make sure you don’t let package to create tables (you can miss this step because it wants to create tables anyway). Save package to SSIS. 2. Modify import and export package Now let’s clean up the package and remove all faulty crap. Connect SQL Server Management Studio to SSIS instance. Select the package you just saved and export it to your hard disc. Run Business Intelligence Studio. Create new SSIS project (DON’T MISS THIS STEP). Add package from disc as existing item to project and open it. Move to Control Flow page do one of following: Remove all preparation SQL-tasks and connect Data Flow tasks. Modify all preparation SQL-tasks so the existence of tables is checked before table is created (yes, you have to do it manually). Add new Execute-SQL task as first task in control flow: Open task properties. Assign destination connection as connection to use. Insert the following SQL as command:   EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL' GO   EXEC sp_MSForEachTable 'DELETE FROM ?' GO   Save task. Add new Execute-SQL task as last task in control flow: Open task properties. Assign destination connection as connection to use. Insert the following SQL as command:   EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL' GO   Save task Now connect first Execute-SQL task with first Data Flow task and last Data Flow task with second Execute-SQL task. Now move to Package Explorer tab and change connections under Connection Managers folder. Make source connection to use database PLAIN. Make destination connection to use database CORRECT. Save package and rebuilt the project. Update package using SQL Server Management Studio. Some hints: Make sure you take the package from solution folder because it is saved there now. Don’t overwrite existing package. Use numeric suffix and let Management Studio to create a new version of package. Now you are done with your package. Run it to test it and clean out all the errors you find. TRUNCATE vs DELETE You can see that I used DELETE FROM instead of TRUNCATE. Why? Because TRUNCATE has some nasty limits (taken from MSDN): “You cannot use TRUNCATE TABLE on a table referenced by a FOREIGN KEY constraint; instead, use DELETE statement without a WHERE clause. Because TRUNCATE TABLE is not logged, it cannot activate a trigger. TRUNCATE TABLE may not be used on tables participating in an indexed view.” As I am not sure what tables you have and how they are used I provided here the solution that should work for all scenarios. If you need better performance then in some cases you can use TRUNCATE table instead of DELETE. Conclusion My conclusion is bitter this time although I am very positive guy. It is A.D. 2010 and still we have to write stupid hacks for simple things. Simple tools that existed before are long gone and we have to live mysterious bloatware that is our only choice when using default tools. If you take a look at the length of this posting and the count of steps I had to do for one easy thing you should treat it as a signal that something has went wrong in last years. Although I got my job done I would be still more happy if out of box tools are more intelligent one day.

• Model won't render in my XNA game

  - by Daniel Lopez

  I am trying to create a simple 3D game but things aren't working out as they should. For instance, the mode will not display. I created a class that does the rendering so I think that is where the problem lies. P.S I am using models from the MSDN website so I know the models are compatible with XNA. Code: class ModelRenderer { private float aspectratio; private Model model; private Vector3 camerapos; private Vector3 modelpos; private Matrix rotationy; float radiansy = 0; public ModelRenderer(Model m, float AspectRatio, Vector3 initial_pos, Vector3 initialcamerapos) { model = m; if (model.Meshes.Count == 0) { throw new Exception("Invalid model because it contains zero meshes!"); } modelpos = initial_pos; camerapos = initialcamerapos; aspectratio = AspectRatio; return; } public Vector3 CameraPosition { set { camerapos = value; } get { return camerapos; } } public Vector3 ModelPosition { set { modelpos = value; } get { return modelpos; } } public void RotateY(float radians) { radiansy += radians; rotationy = Matrix.CreateRotationY(radiansy); } public float AspectRatio { set { aspectratio = value; } get { return aspectratio; } } public void Draw() { Matrix world = Matrix.CreateTranslation(modelpos) * rotationy; Matrix view = Matrix.CreateLookAt(this.CameraPosition, this.ModelPosition, Vector3.Up); Matrix projection = Matrix.CreatePerspectiveFieldOfView(MathHelper.ToRadians(45.0f), this.AspectRatio, 1.0f, 10000f); model.Draw(world, view, projection); } } If you need more code just make a comment.

• Cloud Computing and Data Utilization

  - by Ahsan Alam

  Someone recently asked me “is cloud computing going to change the way we perceive data?”. My first instinct was “off course”; but I restrained myself and thought for a moment. Then my answer was “no”. Why do I feel that way? Technology and business have evolved quite a bit in the past few decades; however, the need to effectively view and utilize data hasn't changed. It is not uncommon to see many organization to rely on multiple database management systems (DBMS). Applications and systems are often built to utilize information from all these data sources, and effectively present them to users. In addition to multiple DBMS, corporations are also housing their systems across numerous data centers. In fact, systems and data can reside anywhere around the world with the advent of globalization. Cloud based systems have simply provided us a different place to maintain our data, nothing more. Hosting costs, security and accessibility are different issues; however, the way we utilize and view these data remains the same.

• How to make sure that grub does use menu.lst?

  - by Glen S. Dalton

  On my Ubuntu 9.04 ("Karmic") laptop I suspect grub does not use the /boot/grub/menu.lst file. What happens on boot is that I see a blank screen and nothing happens. When I press ESC I see a boot list which is different from what I would expect from the menu.lst file. The menu lines are different and when I choose the first entry it does not use the kernel options that are in the first entry in menu.lst. Where do the entries that grub uses come from? How can I find out what happens, is there a log? I could not find anything in /var/log/syslog or /var/log/dmesg about grub using a menu.lst. How can I set it to work like expected?

• Cooking With Expression: HTML 5 and Expression Web

  - by David Wesst

  I finally got the first one done! This is the first of a series of webcasts that I have wanted to do for a while. I call it Cooking with Expression because developing great user experiences are very similar to cooking great food. So please, check it out, leave some feedback, and enjoy! --- To kick off the series, we want to talk about some techniques that we will be using throughout the series for the different recipes. Since HTML 5 is literally the future of the web and buzz topic in development today, we thought we would start off with that. In this episode we are going to teach you how to use one of your your present day tools Microsoft Expression Web with HTML 5. Cooking with Expression - HTML 5 in Expression Web from David Wesst on Vimeo.

• Are animated GIFs supported in Google Chrome?

  - by James Goodwin

  I have recently been testing a website and found animated gif images that seem to show fine in IE and Firefox but in Google Chrome they only show briefly and then dissapear! This happens if I view the image on the page or view the file directly. Are there any reported problems in displaying GIFs in Chrome, or is it just being fussy? There seemed to have been some problems in older versions of Chrome, but it's hard to believe something as simple as this wouldn't have been fixed by now. The version of Google Chrome I am using is: 4.1.249.1021 Not sure if this is relevant, but some info about the image: Width: 216 pixels Height: 36 pixels Horizontal resolution: 96dpi Vertical resolution: 96dpi Bit Depth: 32 Frame Count: 3 EDIT: Seems to be a problem relating to the latest beta version of Chrome, as it works fine in 4.0.249

• National Give Camp Weekend - January 14-16, 2011

  - by MOSSLover

  What is a Give Camp?  I get asked this question constantly in the SharePoint Community.  About 3 years ago there was an event called "We Are Microsoft" in Dallas, TX.  A lady named, Toi Wright, gathered up a bunch of charities and gathered up a bunch of IT Professionals in the community.  They met for an entire weekend devising better ways to help these charities with 3 days projects.  None of these charities had in house IT staff or they were lacking.  The time these projects would save would help out other people in the long run.  The first give camp was really popular that a couple guys from Kansas City decided to come up with a give camp in the Kansas City regiona.  The event was called Coders 4 Charity.  I read Jeff Julian's post on the "We Are Microsoft" event that it inspired me to get involved.  i showed up to this event and we were split into teams.  On that team I met a couple really awsome guys: Blake Theiss, Lee Brandt, Tim Wright, and Joe Loux.  We created a SharePoint site for a boyscout troup.  It was my first exposure to Silverlight 1.1.  I had so much fun that I attended the event the next year and the St. Louis Coders 4 Charity.  Last year in 2010 when I moved i searched high and low.  Sure enough they had an event in Philadelphia.  I helped out with two SharePoint Projects for a team of firefighters and another charity.  This year there are a series of give camps around the U.S.  They have consolidated most of the give camps.  The first ever New York City Give Camp is on National Give Camp Day.  If you guys are interested I see there is a give camp in Philadelphia, St. Louis, Northwest Arkansas, Seattle, Atlanta, Houston, and more...Here is a link to the site I would definitely encourage you to get involved: http://givecamp.org/national-givecamp/.  Also, if you feel like it's only developer focused that's entirely wrong.  They need DBAs, Project Leads, Architects, and many other roles fulfilled aside from development.  It is a great experience to meet good people and help out a charity doing what we all love to do.  I strongle encourage getting involved in a give camp.  if you are coming to the NYC Give Camp I would love to meet you.  i will be there on Saturday somewhere in the morning until around dinner time.
