  • Switching main view in WPF

    - by mico
    I know it might be silly, I have just started with WPF. I want to switch to a different view when a user clicks on a control, for example showing a detail page after a click on a list. This view would replace the original. In a web application this would be navigating to a different page. What is the local idiom for that?

  • Suppressing "extra ';'" error in GCC when -pedantic is on

    - by Roman D
    Hi all, I'm building my program with -pedantic flag, which causes an extra ';' error (because of a third-party header using a few macros inconsistently; the error is not shown when -pedantic is off). I don't really feel like turning -pedantic off, and neither do I want to edit the header. Is there any way to suppress this exact error? Like a -Wno-annoying-semicolon-error compiler switch or something?

  • Issue using Visual Studio 2010 compiled C++ DLL in Windows 2000

    - by Jon Tackabury
    I have a very simple DLL written in unmanaged C++ that I access from my application. I recently switch to Visual Studio 2010, and the DLL went from 55k down to 35k with no code changes, and now it will no longer load in Windows 2000. I didn't change any code or compiler settings. I have my defines setup for 0x0500, which should include Windows 2000 support. Has anyone else run into this, or have any ideas of what I can do?

  • How does one enhance Silverlight WritableBitmap quality when replacing UIElements for animations

    - by Stephen Ellis
    I'm doing an animation where I temporarily drop down the visibility of UIElements and overlay WritableBitmap versions of the original Image. The problem I have is that when I do this on element with text, it results in a noticeably blurry and darker image meaning the switch from UIElement to Image is noticeable. Has anyone experienced this and/or know how to deal with this issue?

  • Change table view ( style grouped ) background color ?

    - by Madhup
    Hi all, I am developing an iPad application in which I need a table view ( style grouped ) having background color as clearColor. My problem is [self.tableView setBackgroundColor:[UIColor clearColor]]; works well if the table view style is plain but when I switch to group table view the background color does not changes it stays gray in color. FYI: the contentview background color of tableviewcell also does not change. Is this a bug in iPhone-sdk or I am doing something wrong. Thanks, Madhup

  • Use Java Annotation not to run a method

    - by Michael Mao
    Hi all: I've got a method in my class only for testing purpose : private void printOut(String msg, Object value) { System.out.println(msg + value); } It is a wrapper method for System.out.println(); So I hope, with the use of Annotation, I can choose not to run this method during productive environment while still keep those diagnostic output ready if I am to switch back to debugging environment. Which Annotation shall I put on top of the method name?

  • Dump Linq-To-Sql now that Entity Framework 4.0 has been released?

    - by DanM
    The relative simplicity of Linq-To-Sql as well as all the criticism leveled at version 1 of Entity Framework (especially, the vote of no confidence) convinced me to go with Linq-To-Sql "for the time being". Now that EF 4.0 is out, I wonder if it's time to start migrating over to it. Questions: What are the pros and cons of EF 4.0 relative to Linq-To-Sql? Is EF 4.0 finally ready for prime time? Is now the time to switch over?

  • How to Improve my php image resizer to support alpha png and transparent GIFs

    - by David
    Hi, I use this function to resize images but i end up with ugly creepy image with a black background if it's a transparent GIF or PNG with alpha, however it works perfectly for jpg and normal png. function cropImage($nw, $nh, $source, $stype, $dest) { $size = getimagesize($source); $w = $size[0]; $h = $size[1]; switch($stype) { case 'gif': $simg = imagecreatefromgif($source); break; case 'jpg': $simg = imagecreatefromjpeg($source); break; case 'png': $simg = imagecreatefrompng($source); break; } $dimg = imagecreatetruecolor($nw, $nh); switch ($stype) { case "png": imagealphablending( $dimg, false ); imagesavealpha( $dimg, true ); $transparent = imagecolorallocatealpha($dimg, 255, 255, 255, 127); imagefilledrectangle($dimg, 0, 0, $nw, $nh, $transparent); break; case "gif": // integer representation of the color black (rgb: 0,0,0) $background = imagecolorallocate($simg, 0, 0, 0); // removing the black from the placeholder imagecolortransparent($simg, $background); break; } $wm = $w/$nw; $hm = $h/$nh; $h_height = $nh/2; $w_height = $nw/2; if($w> $h) { $adjusted_width = $w / $hm; $half_width = $adjusted_width / 2; $int_width = $half_width - $w_height; imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h); } elseif(($w <$h) || ($w == $h)) { $adjusted_height = $h / $wm; $half_height = $adjusted_height / 2; $int_height = $half_height - $h_height; imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h); } else { imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h); } imagejpeg($dimg,$dest,100); } Example : cropImage("300","200","original.png","png","new.png"); I use php 5.3.2 and the GD library bundled (2.0.34 compatible) How to make it support transparency? i've added imagealphablending() and imagesavealpha but it didn't work. Or atlast is there any similar good classes? Thanks

  • Checking For Word Wrap In Table Column

    - by Sparafusile
    I'm writing part of a web page that allows a user to build a table and fill it with information. In the course of building the table, the user will be adding additional columns with headers. I'd like to code it so when the combined width of all the headers causes one of them to wrap that the table columns switch to using vertical text (writing-mode: tb-rl). Is there any way, using JavaScript, to determine if the contents of a specific cell have wrapped? Thanks, Spara

  • How to search through all commits in the repository?

    - by Josip
    I have a git repository with few branches and dangling commits. I would like to search all such commits in repository for a specific string. I know how to get a log of all commits in history, but these don't include branches or dangling blobs, just HEAD's history. I want to get them all, to find a specific commit that got misplaced. I would also like to know how to do this in mercurial, as I'm considering the switch.

  • How to implement Scrum?

    - by Kaan
    We're trying to switch to Scrum as our development process but we're not sure how to implement it in the best way possible. We also don't want to pay for expensive software tools until we get scrum working and get positive results. How can we implement scrum using a whiteboard without asking people to write down their time on the board and then also input into our own time tracking software? What kind of methodologies do you use?

  • flash's "useHandCursor = true" not working for Chrome on Mac

    - by fucrate
    I'm developing a flash game using the default SimpleButton object for my buttons and the hand cursor is working just fine on PC Chrome and Firefox and Safari for Mac, but Chrome on Mac is not letting me swap the default cursor for the hand cursor. I've even set useHandCursor to true for every button I add a click event to and am still getting nothing. We've got no other rollover events, so it's important that the cursor switch. Anyone else run into this and have a lil-fixy / workaround?

  • How do the versions of Guava work?

    - by Frór
    I would like to use Guava in a project, but my PM doesn't like the "r05" suffix, saying that it looks like it's not stable. In fact, the part I need is only the Google-Collections 1.0 which is now deprecated (my PM doesn't like that word either). So I don't really get the versioning of Guava/Google-Collections. I'm currently doing the development with GC1.0, but if possible I'll switch to a more recent and stable version.
