  • How do you tell if your migrations are up to date with migratordotnet?

    - by Lance Fisher
    I'm using migratordotnet to manage my database migrations. I'm running them on application setup like this, but I would also like to check on application startup that the migrations are up to date, and provide the option to migrate to latest. How do I tell if there are available migrations that need to be applied? I see that I can get the migrations that were applied like this var asm = Assembly.GetAssembly(typeof(Migration_0001)); var migrator = new Migrator.Migrator("SqlServer", setupInfo.DatabaseConnectionString, asm); var applied = migrator.AppliedMigrations; I like to do something like this: var available = migrator.AvailableMigrations; //this property does not exist.

  • Why is OnDragEnter not called?

    - by Harvey
    I have added the COleDropTarget variable to my view class, Registered it in the OnCreate(), which is being called at startup. I added the OnDragEnter and OnDrop virtual functions (not the others yet, as OnDragLeave). But they are not called when I drag (or drop) a piece of text over them. I just happened to think about the fact that I had already implemented the dropfiles function to the same window. Is this preventing the text drag? What else do I need? TIA, Harvey

    Could someone write simple Perl programs for the following scenarios: convert a list from {1,2,3,4,5,7,9,10,11,12,34} to {1-5,7,9-12,34} to sort a list of negative numbers to insert values to hash array there is a file with content: C1 c2 c3 c4 r1 r2 r3 r4 put it into an hash array where keys = {c1,c2,c3,c4} and values = {r1,r2,r3,r4} There are testcases running each testcase runs as a process and has a process ID. The logs are logged in a logfile process ID appended to each line. Prog to find out if the test case has passed or failed. The program shoud be running till the processes are running and display output.

  • What is the best option for reading Java property files?

    - by Mr Morgan
    Hello I have an application which uses a servlet to read an intialization parameter from web.xml for the location of a property file. The serlvet then creates an instance of a class which stores the location of the file for other programs to read as required. This class has appropriate get and set methods. But my question concerns access to the properties: should the physical property file be read by each program as at runtime or should the properties be stored in memory instead? The properties are not currently altered at runtime but this could change? I've seen various alternative approaches but am not sure which is best. Thanks Mr Morgan

  • drawRect context Error

    - by user361228
    Hi, I heard that a lot of people get a context error by not using drawRect Now I have this: - (void)drawRect:(CGRect)rect { NSLog(@"drawRect: Starts"); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetRGBStrokeColor(context, 1.0, 1.0, 1.0, 1.0); CGContextSetLineWidth(context, 3.0); CGContextMoveToPoint(context, lineStart.x, lineStart.y); CGContextAddLineToPoint(context, lineEnd.x, lineEnd.y); CGContextStrokePath(context); } Error: <Error>: CGContextSetRGBStrokeColor: invalid context Which had work on previous programs, but not on this one. Whats different: I have a view controller, which calls this UIView: -(void)createLine:(CGPoint)start:(CGPoint)end { NSLog(@"createLine: Starts"); lineEnd = start; lineStart = end; self = [super initWithFrame:drawRect:CGRectMake(fmin(lineStart.x, lineEnd.x), fmin(lineStart.y, lineEnd.y), fabs(lineStart.x - lineEnd.x), fabs(lineStart.y - lineEnd.y))]; } This is my first question, and I am not sure how much info code I should be putting here so be easy on me :D Thanks

  • MPI: is there mpi libraries capable of message compression?

    - by osgx
    Sometimes MPI is used to send low-entropy data in messages. So it can be useful to try to compress messages before sending it. I know that MPI can work on very fast networks (10 Gbit/s and more), but many MPI programs are used with cheap network like 0,1G or 1Gbit/s Ethernet and with cheap (slow, low bisection) network switch. There is a very fast Snappy (wikipedia) compression algorithm, which has Compression speed is 250 MB/s and decompression speed is 500 MB/s so on compressible data and slow network it will give some speedup. Is there any MPI library which can compress MPI messages (at layer of MPI; not the compression of ip packets like in PPP). MPI messages are also structured, so there can be some special method, like compression of exponent part in array of double.

  • How can I pre-authorize authopen?

    - by Georg
    I'm using authopen inside one of my programs to modify files owned by root. As can be seen in the screenshot below authopen asks for a admin password. What I'd like to achieve is that the dialog shows my app's name and then passes the authorization to authopen. Code Launching authopen which returns an authorized file descriptor. int pipe[2]; socketpair(AF_UNIX, SOCK_STREAM, 0, pipe); if (fork() == 0) { // child // close parent's pipe close(pipe[0]); dup2(pipe[1], STDOUT_FILENO); const char *authopenPath = "/usr/libexec/authopen"; execl(authopenPath, authopenPath, "-stdoutpipe", [self.device.devicePath fileSystemRepresentation], NULL); NSLog(@"Fatal error, quitting."); exit(-1); } // parent // close childs's pipe close(pipe[1]); // get file descriptor through sockets I'd really like not to use AuthorizationExecuteWithPrivileges because then I'd have to get more rights than I want to.

  • Shared library linking and loading in BusyBox 0.61

    - by Alex Marshall
    Does anybody know how the dynamic linking and shared library loading works in BusyBox 0.61 ? I can't seem to find how this is done. There's no 'ld' present on the embedded system I'm dealing with, nor is there an LD_LIBRARY_PATH variable set anywhere. My motivation for this is to be able to create a symlink in the /lib directory to another directory on a different device (with considerably more storage space) for adding in more shared libraries, as the file system that contains /lib is a ramdisk that gets reloaded on startup and is within a few kb of being completely full (so we can't add more libraries to the image, nor can we obtain devices with more memory for the ramdisk)

  • Eclispe RCP SWT menus for Windows and Mac OS

    - by Raven
    Hi, how do I configure an Eclipse RCP command style menu to match the different menu structures on Windows and on Mac OS? Mac OS X menu example http://images.apple.com/macosx/refinements/images/services_menu_20090902.jpg Windows menu example http://www.flamingpear.com/images/psp8menu.gif In the example you see, the differences in the menu structures. For example has the Mac in its application menu the preference command, the about command and the exit command. These are under Windows usally in the file menu and the about command is found in the help menu. Is there a "standard" way of doing it with RCP programs? It should somehow be possible because Eclipse itself does it. But I can not figure out how.

  • Whats the difference between Process and ProcessStartInfo in C#?

    - by JimDel
    Whats the difference between Process and ProcessStartInfo? Ive used both to launch external programs but there has to be a reason there are two ways to do it. Here are two examples. Process notePad = new Process(); notePad.StartInfo.FileName = "notepad.exe"; notePad.StartInfo.Arguments = "ProcessStart.cs"; notePad.Start(); and ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.FileName = "notepad.exe"; startInfo.Arguments = " ProcessStart.cs "; Process.Start(startInfo) Thanks

  • Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

    - by Michael Kohout
    Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

  • Watin from TeamCity not running as a Windows Service

    - by peter.swallow
    I'm trying to run Watin from within a TeamCity build, using nUnit. All tests run fine locally. I know you cannot run the full Watin tests (i.e. POST) from TeamCity if it is running as a Windows Service. You must start the build agent from a .bat file. But, I don't want to have to login to the server for it to start. I've tried getting a Scheduled Task (in Windows Server 2008) to fire the agent.bat file on StartUp (not Login), but with no luck. Has anyone else got Watin/TeamCity running from a Scheduled Task? Thanks, Pete

  • (VB.NET + WPF) Drag + Drop (to allow user sorting) of stackpanel elements within a Scrollviewer?

    - by Matt H.
    I have good model (I think!) for how to allow a user to drag an element in a stackpanel and reposition it to another location within the stackpanel. However, my Stackpanel is placed within a ScrollViewer, like this (generalized): <ScrollViewer> <StackPanel> ....First item ....Second item ....Third item ....Etc. </StackPanel> <ScrollViewer> Here is the problem, I wish to simulate the functionality of programs like word, where if I am dragging selected content (or an object) outside the viewable area, the window will scroll in the direction of the mouse to see more places to drop my nifty little object. ...i.e. If I move the mouse to the top of my ScrollViewer while dragging a stackpanel's contents, I want the scrollviewer to slowly move up so I can see more locations to drop my content. Any suggestions? If you can help me solve this, you will be a godsend!

  • What is a hardware-id?

    - by Rob
    Some forums that I regularly visit sell premium programs, and to prevent them from being leaked they use hardware-id authentication. That is, first they send you a program to run to grab your HWID, you tell them your HWID, they store it in a database, then they send you the actual program. If your HWID isn't in the database, the program won't run. So what is Hardware-ID, and how is it generated? Why is it that my HWID is different depending on the programmer that sends me a HWID-grabber?

  • In what areas might the use of F# be more appropriate than C#?

    - by Peter McGrattan
    Over the last few years F# has evolved into one of Microsoft's fully supported languages employing many ideas incubated in OCaml, ML and Haskell. Over the last several years C# has extended it's general purpose features by introducing more and more functional language features: LINQ (list comprehension), Lamdas, Closures, Anonymous Delegates and more... Given C#'s adoption of these functional features and F#'s taxonomy as an impure functional language (it allows YOU to access framework libraries or change shared state when a function is called if you want to) there is a strong similarity between the two languages although each has it's own polar opposite primary emphasis. I'm interested in any successful models employing these two languages in your production polyglot programs and also the areas within production software (web apps, client apps, server apps) you have written in F# in the past year or so that you would previously have written in C#. EDIT: Edited based on feedback from close votes with the intent of reducing perceived ambiguity.

  • NSTableView setting the sort column?

    - by overcyn
    I have a NSTableView with multiple columns. clicking each of the columns sorts by the column like in iTunes. However when the tableview first loads the rows are unsorted and no tablecolumn is highlighted or displaying the up/down indicator image. I'm wondering if theres a simple way I can programmatically set the column the table is sorted by and set the indicator image on startup. The only solution I can think of is using [NSTableView setIndicatorImage: inTableColumn:] and [NSTableView setHighlightedColumn:], but that makes it so that clicking on the header doesnt highlight the column. I would rather not have to use tableView:mouseDownInHeaderOfTableColumn: and rewrite the whole click on header to sort thing.

  • How to retain service settings through InstallShield upgrade install

    - by sjohnston
    I have an InstallScript project in IS2010. It has a handful of services that get installed. Some are C++ exes and use the "InstallShield Object for NT Services". Others are Java apps installed as services with Java Service Wrapper through LaunchAppAndWait command line calls. Tomcat is also being installed as a service through a call to its service.bat. When the installer runs in upgrade mode, the services are reinstalled, and the settings (auto vs. manual startup, restart on fail, log-on account, etc.) are reverted to the defaults. I would like to save the service settings before the file transfer and then repopulate them afterward, but I haven't been able to find a good mechanism to do this. How can I save and restore the service settings?

  • List of header file locations for the Havok Physics Engine

    - by QAH
    Hello everyone! I am trying to integrate the Havok physics engine into my small game. It is a really nice SDK, but the header files are all over the place. Many headers are deeply nested in multiple directories. That gets confusing when you are trying to include headers for different important objects. I would like to know if there is a nice guide that will let you know where certian objects are and what headres they are in. I have already looked at Havok's documentation, and I also looked at the reference manual, but they don't give great detail as to where certain classes are located (header location). Also, is there any programs out there that can scan header files and create a list of where objects can be found? Thanks again

  • Does my AMD-based machine use little endian or big endian?

    - by Frank
    I'm going though a computers system course and I'm trying to establish, for sure, if my AMD based computer is a little endian machine? I believe it is because it would be Intel-compatible. Specifically, my processor is an AMD 64 Athlon x2. I understand that this can matter in C programming. I'm writing C programs and a method I'm using would be affected by this. I'm trying to figure out if I'd get the same results if I ran the program on an Intel based machine (assuming that is little endian machine). Finally, let me ask this: Would any and all machines capable of running Windows (XP, Vista, 2000, Server 2003, etc) and, say, Ubuntu Linux desktop be little endian? Thank You, Frank

  • Mac OS X, Can't start/stop MySQL via System Preferences

    - by Steve Kuo
    I downloaded and installed MySQL 5.1.47 for OS X 10.6 using the DMG archive: mysql-5.1.47-osx10.6-x86_64.dmg I also installed MySQL.prefPane and MySQLStartupItem.pkg. MySQL.prefPane is a Preference Pane. The problem is, whenever I attempt to start/stop MySQL from the Preference Pane, System Preferences just hangs. It runs at about 50% CPU forever, eventually I have for force quit System Preferences. The same thing happens if I toggle "Automatically Start MySQL Server on Startup". Basically the MySQL Preference Pane is not functional. Note that I have no problem starting MySQL from the command line: sudo /usr/local/mysql/bin/mysqld_safe I have tried reinstalling MySQL and the Preference Pane. I'm using the standard installation location, nothing out of the ordinary. Every time the MySQL Preference Pane just hangs. I'm doing this on a Macbook Pro (Intel) running OS X 10.6.3. There are no old versions of MySQL on this machine.

  • Virtualizing WindowsXP on Linux Fedora 12 for Photoshop....

    - by Rae
    I am running a Linux server from 2000, I have Fedora12 installed as the OS. I know you can virtualize Windows XP on the system to be able to run Windows programs, but the problem is I My server has only one 1333Mhz Pentium 3 processor and 1G of Ram. granted this is a pretty kick ass computer for the day, but lacking the processor I'm afraid that I will not be able to run Windows virtualization to support Photoshop CS3. Is there any program out there that runs similar to Photoshop, like windows Digital Image suite 10, that will run smoothly in my Linux Fedora 12 environment? or can I virtualize windows and run the Windows digital image suite 10, without slowing or corrupting my system?
