• How to propertly reference a namespace for Microsoft.Sdc.Tasks.XmlFile.GetValue

  - by æther

  Hi, i want to use MSBuild to insert a custom xml element into web.config. After looking up online, i found such solution: 1) Store element in the .build file in projectextensions <ProjectExtensions> <CustomElement name="CustomElementName"> ... </CustomElement> </ProjectExtensions> 2) Retrieve the element with GetValue <Target name="ModifyConfig"> <XmlFile.GetValue Path="$(MSBuildProjectFullPath)" XPath="Project/ProjectExtensions/CustomElement[@name='CustomElementName']"> <Output TaskParameter="Value" PropertyName="CustomElementProperty"/> </XmlFile.GetValue> </Target> This will not work as i need to reference a namespace the .build project is using for it to find the needed element (checked the .build file with XPath Visualizer). So, i look up for a further solution and come to this: <ItemGroup> <XmlNamespace Include="MSBuild"> <Prefix>msb</Prefix> <Uri>http://schemas.microsoft.com/developer/msbuild/2003</Uri> </XmlNamespace> </ItemGroup> <Target name="ModifyConfig"> <XmlFile.GetValue Path="$(MSBuildProjectFullPath)" Namespaces="$(XmlNamespace)" XPath="/msb:Project/msb:ProjectExtensions/msb:CustomElement[@name='CustomElementName']" > <Output TaskParameter="Value" PropertyName="CustomElementProperty"/> </XmlFile.GetValue> </Target> But for some reason namespace is not recognized - MSBuild reports the following error: C:...\mybuild.build(53,9): error : A task error has occured. C:...\mybuild.build(53,9): error : Message = Namespace prefix 'msb' is not defined. I tried some variations of referencing it differently but none work, and there is not much about propertly referencing those namespaces online also. Can you tell me what am i doing wrong and how to do it propertly?

• Optimizing wireless router speed and minimizing interference.

  - by Tchalvak

  I've been experiencing problems with my wireless connectivity lately, and want to make sure that it's not related to the abundance of other wireless routers here in my building. So, what I'm looking for is a method (probably via some application or another) to audit the wireless channels (and other factors that might be important that I don't even know of yet) that are floating through the aether around me. Ubuntu or other linux apps are preferred, but some kind of windows/mac solution is possible, since I do have other OSes around me that I could install & test on. Router: netgear WGT624 v3 Hearsay tells me that channels 1, 6, and 11 are "non-overlapping" (I expect they aren't used for non-wireless-router purposes or something, not sure how they couldn't overlap with other routers using other channels), so perhaps my best choices of channel are limited, so if channels aren't really a big concern, I'd be happy to get links to other optimizations that I should look into.

• QGraphicsView scrolling and image scaling/cropping

  - by boohoo

  I would like to have a background image in my QGraphicsView that is always scaled (and cropped if necessary) to the size of the viewport, without scrollbars and without scrolling with the keyboard and mouse. The example below is what I am doing to scale and crop an image in the viewport, but I am using random values for the cropping that are pulled out of the aether. I would like a logical solution? MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); scene = new QGraphicsScene(this); ui->graphicsView->resize(800, 427); // MainWindow is 800x480, GraphicsView is 800x427. I want an image that // is the size of the graphicsView. ui->graphicsView->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff); ui->graphicsView->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff); // the graphicsView still scrolls if the image is too large, but // displays no scrollbars. I would like it not to scroll (I want to // add a scrolling widget into the QGraphicsScene later, on top of // the background image.) QPixmap *backgroundPixmap = new QPixmap(":/Valentino_Bar_Prague.jpg"); QPixmap sized = backgroundPixmap->scaled( QSize(ui->graphicsView->width(), ui->graphicsView->height()), Qt::KeepAspectRatioByExpanding); // This scales the image too tall QImage sizedImage = QImage(sized.toImage()); QImage sizedCroppedImage = QImage(sizedImage.copy(0,0, (ui->graphicsView->width() - 1.5), (ui->graphicsView->height() + 19))); // so I try to crop using copy(), and I have to use these values // and I am unsure why. QGraphicsPixmapItem *sizedBackground = scene->addPixmap( QPixmap::fromImage(sizedCroppedImage)); sizedBackground->setZValue(1); ui->graphicsView->setScene(this->scene); } I would like to know a way to scale and crop an image to the size of the QGraphicsView that will work even when I resize the QGraphicsView. Where are the 1.5 and 19 coming from?
