• Objective C++ support in autotools

  - by vian

  I'm working under Mac OS X 10.6.5 autoconf version 2.68 automake version 1.11.1 In a large project that is built using autoconf, automake, I need to add .mm files to the library sources. When I add them to the library_SOURCES variable they won't compile even after I use AS_IF([test "$with_target" = "quartz"], [AC_PROG_OBJCXX]) in my configure.ac. The test is passed successfully and it event outputs checking whether we are using the GNU Objective C++ compiler... yes and .mm files don't compile. Where can I look to solve this problem?

• DevExpress ASP.NET MVC Combobox not showing the values

  - by Taskos George

  In my PartialView I add a grid with a column that I need to be a combobox in this way. settings.Columns.Add(column => { column.FieldName = "TheFieldName"; column.Caption = ""ACaption; column.ColumnType = MVCxGridViewColumnType.ComboBox; var comboBoxProperties = column.PropertiesEdit as ComboBoxProperties; comboBoxProperties.DataSource = ViewData["MyListOfObjects"]; comboBoxProperties.TextField = "Description"; comboBoxProperties.ValueField = "Description"; comboBoxProperties.ValueType = typeof(String); }); The ViewData is populated in the Index method of the Controller and I have checked that it is populated with objects that contain values. The Combobox in the PopupEditForm not showing anything. Any idea what could be wrong? Regards.

• Problem: adding feature in MOSS 2007

  - by Anoop

  Hi All, I have added a menu item in 'Actions' menu of a document library as follows(Using features: explained in MSDN How to: Add Actions to the User Interface: http://msdn.microsoft.com/en-us/library/ms473643.aspx): feature.xml as follows: <?xml version="1.0" encoding="utf-8" ?> <Feature Id="51DEF381-F853-4991-B8DC-EBFB485BACDA" Title="Import From REP" Description="This example shows how you can customize various areas inside Windows SharePoint Services." Version="1.0.0.0" Scope="Site" xmlns="http://schemas.microsoft.com/sharepoint/"> <ElementManifests> <ElementManifest Location="ImportFromREP.xml" /> </ElementManifests> </Feature> ImportFromREP.xml is as follows: <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <!-- Document Library Toolbar Actions Menu Dropdown --> <CustomAction Id="ImportFromREP" RegistrationType="List" RegistrationId = "101" GroupId="ActionsMenu" Rights="AddListItems" Location="Microsoft.SharePoint.StandardMenu" Sequence="1000" Title="Import From REP"> <UrlAction Url="/_layouts/ImportFromREP.aspx?ActionsMenu"/> </CustomAction> </Elements> I have successfully installed and activated the feature. Normal case: Now if i login with the user having atleast 'Contribute' permission on the document library, i am able to see the menu item 'Import From REP' (in 'Actions' menu)in root folder as well as in all subfolders. Problem case: If user is having view rights on the document library but add/delete rights on a perticular subfolder(say 'subfolder') inside the document library: Menu item 'Import From REP' is not visible on root folder level as well as 'Upload' menu is also not visible. which is o.k. because user does not have AddListItems right on root folder but it is also not visible in 'subfolder' while 'Upload' menu is visible as user has add/delete rights on the 'subfolder'. did i mention a wrong value of attribute Rights(Rights="AddListItems") in the xml file?? If so, what should be the correct value? What should i do to simulate the behaviour of 'Upload' menu??(i.e. when 'Upload' menu is visible, 'Import From REP' menu is visible and when 'Upload' menu is not visible 'Import From REP' menu is also not visible. ) Thanks in advance Anoop

• Silverlight DataGrid refresh problem

  - by Krimson

  Hi, I have encountered a problem when I refresh the observable collection behind my Silverlight DataGrid (the DataGrid binds to a PagedCollectionView with an ObservableCollection as source). When I clear the observable collection and add the new items to the collection the DataGrid repositions to the top. I want the DataGrid to keep the scroll position. This seems to somewhat happen if I remove the items in the collection one-by-one with the RemoveAt mehtod and the add the new items one-by-one. But why is there this difference between removing all the items at once with the Clear method and removing the items one-by-one with the RemoveAt method? Best Regards, Jesper

• Insert a doctype into an XML document (Java/ SAX)

  - by Thom Nichols

  Imagine you have an XML document and imagine you have the DTD but the document itself doesn't actually specify a DOCTYPE ... How would you insert the DOCTYPE declaration, preferably by specifying it on the parser (similar to how you can set the schema for a document that will be parsed) or by inserting the necessary SAX events via an XMLFilter or the like? I've found many references to EntityResolver, but that is what's invoked once a DOCTYPE is found during parsing and it's used to point to a local DTD file. EntityResolver2 appears to have what I'm looking for but I haven't found any examples of usage. This is the closest I've come thus far: (code is Groovy, but close enough that you should be able to understand it...) import org.xml.sax.* import org.xml.sax.ext.* import org.xml.sax.helpers.* class XmlFilter extends XMLFilterImpl { public XmlFilter( XMLReader reader ) { super(reader) } @Override public void startDocument() { super.startDocument() super.resolveEntity( null, 'file:///./entity.dtd') println "filter startDocument" } } class MyHandler extends DefaultHandler2 { public InputSource resolveEntity(String name, String publicId, String baseURI, String systemId) { println "entity: $name, $publicId, $baseURI, $systemId" return new InputSource(new StringReader('<!ENTITY asdf "&#161;">')) } } def handler = new MyHandler() def parser = XMLReaderFactory.createXMLReader() parser.setFeature 'http://xml.org/sax/features/use-entity-resolver2', true def filter = new XmlFilter( parser ) filter.setContentHandler( handler ) filter.setEntityResolver( handler ) filter.parse( new InputSource(new StringReader('''<?xml version="1.0" ?> <test>one &asdf; two! &nbsp; &iexcl;&pound;&cent;</test>''')) ); I see resolveEntity called but still hit org.xml.sax.SAXParseException: The entity "asdf" was referenced, but not declared. at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1231) at org.xml.sax.helpers.XMLFilterImpl.parse(XMLFilterImpl.java:333) I guess this is because there's no way to add SAX events that the parser knows about, I can only add events via a filter that's upstream from the parser which are passed along to the ContentHandler. So the document has to be valid going into the XMLReader. Any way around this? I know I can modify the raw stream to add a doctype or possibly do a transform to set a DTD... Any other options?

• How to manage maintenance/bug-fix branches in Subversion when setup projects need to be built?

  - by Mike Spross

  We have a suite of related products written in VB6, with some C# and VB.NET projects, and all the source is kept in a single Subversion repository. We haven't been using branches in Subversion (although we do tag releases now), and simply do all development in trunk, creating new releases when the trunk is stable enough. This causes no end of grief when we release a new version, issues are found with it, and we have already begun working on new features or major changes to the trunk. In the past, we would address this in one of two ways, depending on the severity of the issues and how stable we thought the trunk was: Hurry to stabilize the trunk, fix the issues, and then release a maintenance update based on the HEAD revision, but this had the side effect of releases that fixed the bugs but introduced new issues because of half-finished features or bugfixes that were in trunk. Make customers wait until the next official release, which is usually a few months. We want to change our policies to better deal with this situation. I was considering creating a "maintenance branch" in Subversion whenever I tag an official release. Then, new development would continue in trunk, and I can periodically merge specific fixes from trunk into the maintenance branch, and create a maintenance release when enough fixes are accumulated, while we continue to work on the next major update in parallel. I know we could also have a more stable trunk and create a branch for new updates instead, but keeping current development in trunk seems simpler to me. The major problem is that while we can easily branch the source code from a release tag and recompile it to get the binaries for that release, I'm not sure how to handle the setup and installer projects. We use QSetup to create all of our setup programs, and right now when we need to modify a setup project, we just edit the project file in-place (all the setup projects and any dependencies that we don't compile ourselves are stored on a separate server, and we make sure to always compile the setup projects on that machine only). However, since we may add or remove files to the setup as our code changes, there is no guarantee that today's setup projects will work with yesterday's source code. I was going to put all the QSetup projects in Subversion to deal with this, but I see some problems with this approach. I want the creation of setup programs to be as automated as possible, and at the very least, I want a separate build machine where I can build the release that I want (grabbing the code from Subversion first), grab the setup project for that release from Subversion, recompile the setup, and then copy the setup to another place on the network for QA testing and eventual release to customers. However, when someone needs to change a setup project (to add a new dependency that trunk now requires or to make other changes), there is a problem. If they treat it like a source file and check it out on their own machine to edit it, they won't be able to add files to the project unless they first copy the files they need to add to the build machine (so they are available to other developers), then copy all the other dependencies from the build machine to their machine, making sure to match the folder structure exactly. The issue here is that QSetup uses absolute paths for any files added to a setup project. However, this means installing a bunch of setup dependencies onto development machines, which seems messy (and which could destabilize the development environment if someone accidentally runs the setup project on their machine). Also, how do we manage third-party dependencies? For example, if the current maintenance branch used MSXML 3.0 and the trunk now requires MSXML 4.0, we can't go back and create a maintenance release if we have already replaced the MSXML library on the build machine with the latest version (assuming both versions have the same filename). The only solution I can think is to either put all the third-party dependencies in Subversion along with the source code, or to make sure we put different library versions in separate folders (i.e. C:\Setup\Dependencies\MSXML\v3.0 and C:\Setup\Dependencies\MSXML\v4.0). Is one way "better" or more common than the other? Are there any best practices for dealing with this situation? Basically, if we release v2.0 of our software, we want to be able to release v2.0.1, v2.0.2, and v.2.0.3 while we work on v2.1, but the whole setup/installation project and setup dependency issue is making this more complicated than the typical "just create a branch in Subversion and recompile as needed" answer.

• do-while loop in Python?

  - by Eye of Hell

  I need to emulate a do-while loop in a python. But, unfortunately, following straightforward code does not work: l = [ 1, 2, 3 ] i = l.__iter__() s = None while True : if s : print s try : s = i.next() except StopIteration : break print "done" Instead of "1,2,3,done" I have the following output: [stdout:]1 [stdout:]2 [stdout:]3 None['Traceback (most recent call last): ', ' File "test_python.py", line 8, in <module> s = i.next() ', 'StopIteration '] What can I do in order to catch 'stop iteration' excepton and break a while loop properly? Example why such thing may be needed. State machine: s = "" while True : if state is STATE_CODE : if "//" in s : tokens.add( TOKEN_COMMENT, s.split( "//" )[1] ) state = STATE_COMMENT else : tokens.add( TOKEN_CODE, s ) if state is STATE_COMMENT : if "//" in s : tokens.append( TOKEN_COMMENT, s.split( "//" )[1] ) else state = STATE_CODE # re-evaluate same line continue try : s = i.next() except StopIteration : break

• Ruby SerialPorts Gem

  - by Seth Archer

  Using Ruby SerialPorts Gem to interact with hardware. When I write a byte array to the hardware using a program called "Serial Port Monitor" the hardware responds correctly. However, when I write the same byte array using ruby it doesn't work unless I do a read request just before the write request. This device doesn't respond correctly with this sp = SerialPort.new(args) sp.write [200.chr, 30.chr, 6.chr, 5.chr, 1.chr, 2.chr, 0.chr, 244.chr] But it does if I add a read request before the write. Like this sp SerialPort.new(args) sp.read sp.write [200.chr, 30.chr, 6.chr, 5.chr, 1.chr, 2.chr, 0.chr, 244.chr] This works, but I'm at a loss as to why. I should also add that the first snippet does work occasionally maybe 1/10 of the time.

  Dears, I am now making some RESTful web service with MySQL database. I used NetBeans to create the resources of RESTful service with MySQL, and now I can now using GET and POST/PUT to list and add/modify data entities in the MySQL server. Currently, I wish to make some calculations right after a client makes the POST activities, then the posted data with calculated results will be inserted into the MySQL database. I am very new to this, I guess I need to add some functions and call them to calculate but I don't know where and how to do that : ( Could any one help me on this issue?

• Neural Networks in C# using NeuronDotNet

  - by kingrichard2005

  Hello, I'm testing the NeuronDotNet library for a class assignment using C#. I have a very simple console application that I'm using to test some of the code snippets provided in the manual fro the library, the goal of the assignment is to teach the program how to distinguish between random points in a square which may or may not be within a circle that is also inside the square. So basically, which points inside the square are also inside the circle. Here is what I have so far: namespace _469_A7 { class Program { static void Main(string[] args) { //Initlaize the backpropogation network LinearLayer inputLayer = new LinearLayer(2); SigmoidLayer hiddenLayer = new SigmoidLayer(8); SigmoidLayer outputLayer = new SigmoidLayer(2); new BackpropagationConnector(inputLayer, hiddenLayer); new BackpropagationConnector(hiddenLayer, outputLayer); BackpropagationNetwork network = new BackpropagationNetwork(inputLayer, outputLayer); //Generate a training set for the ANN TrainingSet trainingSet = new TrainingSet(2, 2); //TEST: Generate random set of points and add to training set, //for testing purposes start with 10 samples; Point p; Program program = new Program(); //Used to access randdouble function Random rand = new Random(); for(int i = 0; i < 10; i++) { //These points will be within the circle radius Type A if(rand.NextDouble() > 0.5) { p = new Point(rand.NextDouble(), rand.NextDouble()); trainingSet.Add(new TrainingSample(new double[2] { p.getX(), p.getY() }, new double[2] { 1, 0 })); continue; } //These points will either be on the border or outside the circle Type B p = new Point(program.randdouble(1.0, 4.0), program.randdouble(1.0, 4.0)); trainingSet.Add(new TrainingSample(new double[2] { p.getX(), p.getY() }, new double[2] { 0, 1 })); } //Start network learning network.Learn(trainingSet, 100); //Stop network learning //network.StopLearning(); } //generates a psuedo-random double between min and max public double randdouble(double min, double max) { Random rand = new Random(); if (min > max) { return rand.NextDouble() * (min - max) + max; } else { return rand.NextDouble() * (max - min) + min; } } } //Class defines a point in X/Y coordinates public class Point { private double X; private double Y; public Point(double xVal, double yVal) { this.X = xVal; this.Y = yVal; } public double getX() { return X; } public double getY() { return Y; } } } This is basically all that I need, the only question I have is how to handle output?? More specifically, I need to output the value of the "step size" and the momentum, although it would be nice to output other information as well. Anyone with experience using NeuronDotNet, your input is appreciated.

• UIWebView leak? Can someone confirm?

  - by Shaggy Frog

  I was leak-testing my current project and I'm stumped. I've been browsing like crazy and tried everything except chicken sacrifice. I just created a tiny toy project app from scratch and I can duplicate the leak in there. So either UIWebView has a leak or I'm doing something really silly. Essentially, it boils down to a loadRequest: call to a UIWebView object, given an URLRequest built from an NSURL which references a file URL, for a file in the app bundle, which lives inside a folder that Xcode is including by reference. Phew. The leak is intermittent but still happens ~75% of the time (in about 20 tests it happened about 15 times). It only happens on the device -- this does not leak in the simulator. I am testing targeting both iPhone OS 3.1.2 and 3.1.3, on an original (1st Gen) iPod Touch that is using iPhone OS 3.1.3. To reproduce, just create a project from scratch. Add a UIWebView to the RootViewController's .xib, hook it up via IBOutlet. In the Finder, create a folder named "html" inside your project's folder. Inside that folder, create a file named "dummy.html" that has the word "Test" in it. (Does not need to be valid HTML.) Then add the html folder to your project in Xcode by choosing "Create Folder References for any added folders" Add the following to viewDidLoad NSString* resourcePath = [[NSBundle mainBundle] resourcePath]; NSString* filePath = [[resourcePath stringByAppendingPathComponent:@"html"] stringByAppendingPathComponent:@"dummy.html"]; NSURL* url = [[NSURL alloc] initFileURLWithPath:filePath]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; // <-- this creates the leak! [browserView loadRequest:request]; [url release]; I've tried everything from setting delegate for the UIWebView and implementing UIWebViewDelegate, to not setting a delegate in IB, to not setting a delegate in IB and explicitly setting the web view's delegate property to nil, to using alloc/init instead of getting autoreleased NSURLRequests (and/or NSURLs)... I tried the answer to a similar question (setting the shared URL cache to empty) and that did not help. Can anyone help?

• UITabBarController rotation problem with popViewControllerAnimated and selectedIndex (iPhone SDK)

  - by rjobidon

  Hi! This is a very important auto rotate issue and easy to reproduce. My application has a UITabBarController. Each tab is a UINavigationController. Auto rotation is handled with normal calls to shouldAutorotateToInterfaceOrientation and didRotateFromInterfaceOrientation. The interface rotates normally until I call UIViewController.popViewControllerAnimated and change UITabBarController.selectedIndex. Steps to reproduce: Create a demo Tab Bar Application. Add the following code to the App Delegate .h file: #import <UIKit/UIKit.h> @interface TestRotationAppDelegate : NSObject { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; -(void)doAction; @end // Redefine the interface to cach rotation messages @interface UITabBarController (TestRotation1AppDelegate) @end Add the following code to the App Delegate .m file: #import "TestRotationAppDelegate.h" @implementation TestRotationAppDelegate @synthesize window; @synthesize tabBarController; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; return YES; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } -(void)dealloc { [tabBarController release]; [window release]; [super dealloc]; } @end @implementation UITabBarController (TestRotation1AppDelegate) -(void)viewDidLoad { [super viewDidLoad]; // Add a third tab and push a view UIViewController *view1 = [[UIViewController alloc] init]; view1.title = @"Third"; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:view1]; NSMutableArray *array = [[NSMutableArray alloc] init]; [array addObjectsFromArray:self.viewControllers]; [array addObject:nav]; self.viewControllers = array; // Push view2 inside the third tab UIViewController *view2 = [[UIViewController alloc] init]; [nav pushViewController:view2 animated:YES]; // Create a button to pop view2 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = CGRectMake(50, 50, 220, 38); [button setTitle:@"Pop this view" forState:UIControlStateNormal]; [button addTarget:self action:@selector(doAction) forControlEvents:UIControlEventTouchUpInside]; [view2.view addSubview:button]; } -(void) doAction { // ROTATION PROBLEM BEGINS HERE // Remove one line of code and the problem doesn't occur. [self.selectedViewController popViewControllerAnimated:YES]; self.selectedIndex = 0; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end The interface auto rotates normally until you tap the button on tab #3. Your help will be geatly appreciated!

• Bing Maps - how to link to a push pin from a link outside the map

  - by Rajah

  I have a Virtual Earth Maps (Bing Maps??) to which I have added a set of pushpins. Each pushpin is labelled 1 to n. In addition to adding pushpins to the map, I also add text to the web-page that contains the description to each pushpin. I would like to add a link to the text outside the map, that when clicked will open the balloon associated with the corresponding pushpin. How do I open the balloon associated with a pushpin, through a link that exists outside the map? To get a better understanding, look at my map: link. When you click load, PushPins are added to the map. I would like to have a link from the list on the right of the map, that opens the corresponding PushPin. Thanks in advance!

• Autoconf/Automake "configure.ac:2: option `-Wall' not recognized"

  - by Atmocreations

  Hello I'm trying to start with autoconf / automake for a new project. To get started, I'm reading "Using GNU Autotools" and trying to build the Hello-World-Tutorial. The required files from page 96 (real Page=105 because it's a LaTeX-Presentation) configure.ac, Makefile.am and src/Makefile.am look exactly as stated in the document. After that I tried: $ autoreconf --install configure.ac:2: option `-Wall' not recognized autoreconf: automake failed with exit status: 1 Well, it seems that automake doesn't like the second line: AM_INIT_AUTOMAKE([-Wall -Werror foreign]) Therefore I executed: $ autoreconf -v --install autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal autoreconf: configure.ac: tracing autoreconf: configure.ac: not using Libtool autoreconf: running: /usr/bin/autoconf autoreconf: running: /usr/bin/autoheader autoreconf: running: automake --add-missing --copy --no-force configure.ac:2: option `-Wall' not recognized autoreconf: automake failed with exit status: 1 You can see easily that autoconf runs automake --add-missing --copy --no-force which I repeated with the verbose-option. And it only returns this: $ automake -v --add-missing --copy --no-force automake: thread 0: reading autoconf --trace=_LT_AC_TAGCONFIG:\$f:\$l::\$d::\$n::\${::}% --trace=AM_ENABLE_MULTILIB:\$f:\$l::\$d::\$n::\${::}% --trace=AM_SILENT_RULES:\$f:\$l::\$d::\$n::\${::}% --trace=AC_INIT:\$f:\$l::\$d::\$n::\${::}% --trace=_AM_COND_IF:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CONFIG_FILES:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CANONICAL_TARGET:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CONFIG_LIBOBJ_DIR:\$f:\$l::\$d::\$n::\${::}% --trace=AC_FC_SRCEXT:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CANONICAL_HOST:\$f:\$l::\$d::\$n::\${::}% --trace=AM_GNU_GETTEXT:\$f:\$l::\$d::\$n::\${::}% --trace=AC_LIBSOURCE:\$f:\$l::\$d::\$n::\${::}% --trace=AM_INIT_AUTOMAKE:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CANONICAL_BUILD:\$f:\$l::\$d::\$n::\${::}% --trace=AM_AUTOMAKE_VERSION:\$f:\$l::\$d::\$n::\${::}% --trace=_AM_SUBST_NOTMAKE:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CONFIG_AUX_DIR:\$f:\$l::\$d::\$n::\${::}% --trace=sinclude:\$f:\$l::\$d::\$n::\${::}% --trace=AM_PROG_CC_C_O:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CONFIG_LINKS:\$f:\$l::\$d::\$n::\${::}% --trace=AC_REQUIRE_AUX_FILE:\$f:\$l::\$d::\$n::\${::}% --trace=m4_sinclude:\$f:\$l::\$d::\$n::\${::}% --trace=LT_SUPPORTED_TAG:\$f:\$l::\$d::\$n::\${::}% --trace=AM_CONDITIONAL:\$f:\$l::\$d::\$n::\${::}% --trace=AC_CONFIG_HEADERS:\$f:\$l::\$d::\$n::\${::}% --trace=AM_MAINTAINER_MODE:\$f:\$l::\$d::\$n::\${::}% --trace=m4_include:\$f:\$l::\$d::\$n::\${::}% --trace=_AM_COND_ELSE:\$f:\$l::\$d::\$n::\${::}% --trace=AM_GNU_GETTEXT_INTL_SUBDIR:\$f:\$l::\$d::\$n::\${::}% --trace=_AM_COND_ENDIF:\$f:\$l::\$d::\$n::\${::}% --trace=AC_SUBST_TRACE:\$f:\$l::\$d::\$n::\${::}% configure.ac:2: option `-Wall' not recognized Anybody an idea why this doesn't work?

Do you know any base where to start and what I have to pay attention for? I'm on Ubuntu 9.10 64bit. Any help is appreciated. Thanks in advance, regards

• Modifying SQL Server Schema Collection

  - by Mevdiven

  SQL Server XML Schema Collection is an interesting concept and I find it very useful when designing dynamic data content. However as I work my way through implementing Schema Collections, I find it very difficult to maintain them. Schema Collection DDL allows only CREATE and ALTER/ADD nodes to existing schemes. CREATE XML SCHEMA COLLECTION [ <relational_schema>. ]sql_identifier AS 'XSD Content' ALTER XML SCHEMA COLLECTION [ <relational_schema>. ]sql_identifier ADD 'Schema Component' When you want to remove any node from a schema you have to issue following DDL's. If that schema collection assigned to a table column, you have to alter table to remove schema collection association from that column Drop the schema collection object Re-Create schema collection Alter table column to re-associate schema collection to that column. This is pain when it comes to 100+ of schemes in a collection. Also you have to re-create XML indexes all over again, if any. Any solutions, suggestions, tricks to make this schema collection object editing process easier?

• WPF - Bind Menu Item

  - by Miguel

  Hello, I am creating a menu and binding the menu items ate runtime as follows but I am not able to make it work. I am creating the menu as follows: Menu menu = new Menu(); menu.Items.Add(new MenuItem { Command = new PackCommand(), Header = "Pack" }); DockPanel.SetDock(menu, Dock.Top); content.Children.Add(menu); And I am implementing ICommand: public static class PackCommand : ICommand { Boolean CanExecute(object parameter) { return true; } void Execute(object parameter) { Packer packer = new Packer(); packer.Run(); } } I am not sure how to bind the menu item. Why CanExecute? Shouldn't it always? I only want to run packer.Run when the buttom is clicked. I think I should implement ICommand but I am not even sure I should do this? Could someone please help me out? Thanks, Miguel

• Android Map Performance poor because of many Overlays?

  - by Dave

  Hi, I have a map in my android application that shows many markers (~20-50). But the app performs very poor when i try to scroll/zoom (in Google Android Maps i did a sample search for pizza and there were also some 20-50 results found and i didn't notice any particular performance problems when zooming/scrolling through the map). Here is my (pseudo)code: onCreate() { .... drawable = this.getResources().getDrawable(R.drawable.marker1); itemizedOverlay = new MyItemizedOverlay(drawable,mapView); ... callWebServiceToRetrieveData(); createMarkers(); } createMarkers(){ for(elem:bigList){ GeoPoint geoPoint = new GeoPoint((int)(elem.getLat()*1000000), (int) (elem.getLon()*1000000)); OverlayItem overlayItem = new OverlayItem(geoPoint, elem.getName(), elem.getData()); itemizedOverlay.addOverlay(overlayItem); mapOverlays.add(itemizedOverlay); } mapView.invalidate(); } the MyItemizedOverlay.addOverlay looks like this: public void addOverlay(OverlayItem overlay) { m_overlays.add(overlay); populate(); }

• WPF absolute positioning in InkCanvas

  - by Nilu

  Hi, I'm trying to position a rectangle in an InkCanvas. I am using the following method. Unfortunately when I add the rectangle it gets displayed at (0,0). Although when I query to see the whether the left property is 0 I get a non zero values. Does anyone know why this might be? Cheers, Nilu InkCanvas _parent = new InkCanvas(); private void AddDisplayRect(Color annoColour, Rect bounds) { Rectangle displayRect = new Rectangle(); Canvas.SetTop(displayRect, bounds.Y); Canvas.SetLeft(displayRect, bounds.X); // check to see if the property is set Trace.WriteLine(Canvas.GetLeft(displayRect)); displayRect.Width = bounds.Width; displayRect.Height = bounds.Height; displayRect.Stroke = new SolidColorBrush(annoColour); displayRect.StrokeThickness = 1; _parent.Children.Add(displayRect); }

• Create a grid in WPF as Template programmatically

  - by wickie79

  I want to create a basic user control with a style programmatically. In this style i want to add a Grid (no problem), but i dont can add column definitions to this grid. My example code is ControlTemplate templ = new ControlTemplate(); FrameworkElementFactory mainPanel = new FrameworkElementFactory(typeof(DockPanel)); mainPanel.SetValue(DockPanel.LastChildFillProperty, true); FrameworkElementFactory headerPanel = new FrameworkElementFactory(typeof(StackPanel)); headerPanel.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal); headerPanel.SetValue(DockPanel.DockProperty, Dock.Top); mainPanel.AppendChild(headerPanel); FrameworkElementFactory headerImg = new FrameworkElementFactory(typeof(Image)); headerImg.SetValue(Image.MarginProperty, new Thickness(5)); headerImg.SetValue(Image.HeightProperty, 32d); headerImg.SetBinding(Image.SourceProperty, new Binding("ElementImage") { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent) }); headerPanel.AppendChild(headerImg); FrameworkElementFactory headerTitle = new FrameworkElementFactory(typeof(TextBlock)); headerTitle.SetValue(TextBlock.FontSizeProperty, 16d); headerTitle.SetValue(TextBlock.VerticalAlignmentProperty, VerticalAlignment.Center); headerTitle.SetBinding(TextBlock.TextProperty, new Binding("Title") { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent) }); headerPanel.AppendChild(headerTitle); FrameworkElementFactory mainGrid = new FrameworkElementFactory(typeof(Grid)); FrameworkElementFactory c1 = new FrameworkElementFactory(typeof(ColumnDefinition)); c1.SetValue(ColumnDefinition.WidthProperty, new GridLength(1, GridUnitType.Star)); FrameworkElementFactory c2 = new FrameworkElementFactory(typeof(ColumnDefinition)); c2.SetValue(ColumnDefinition.WidthProperty, new GridLength(1, GridUnitType.Auto)); FrameworkElementFactory c3 = new FrameworkElementFactory(typeof(ColumnDefinition)); c3.SetValue(ColumnDefinition.WidthProperty, new GridLength(3, GridUnitType.Star)); FrameworkElementFactory colDefinitions = new FrameworkElementFactory(typeof(ColumnDefinitionCollection)); colDefinitions.AppendChild(c1); colDefinitions.AppendChild(c2); colDefinitions.AppendChild(c3); mainGrid.AppendChild(colDefinitions); mainPanel.AppendChild(mainGrid); FrameworkElementFactory content = new FrameworkElementFactory(typeof(ContentPresenter)); content.SetBinding(ContentPresenter.ContentProperty, new Binding() { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent), Path = new PropertyPath("Content") }); mainGrid.AppendChild(content); templ.VisualTree = mainPanel; Style mainStyle = new Style(); mainStyle.Setters.Add(new Setter(UserControl.TemplateProperty, templ)); this.Style = mainStyle; But the creation of FrameworkElementFactory with type ColumnDefinitionCollection will throw an exception "'ColumnDefinitionCollection' type must derive from FrameworkElement, FrameworkContentElement, or Visual3D." Who can help me?
