  • Hibernate: Perform criteria query with Sub-Select AND Left-Outer join?

    - by Markos Fragkakis
    Can I perform a Criteria query with Sub-Select AND Left-Outer join? For example, I have A 1-many B 1-many C. With Criteria.createAlias ("b", "b", Criteria.LEFT_JOIN) I can perform Left Outer join. With Criteria.setFetchMode ("b", org.hibernate.FetchMode.DEFAULT) I can perform Join with the default fetching strategy. I assume that having set @org.hibernate.annotations.FetchMode.SUBSELECT in both A.B and B.C is enough (is it?). Question 1: Why does org.hibernate.FetchMode not have SUBSELECT option, whereas the org.hibernate.annotations.FetchMode does? Question 2: Can I perform a Criteria query with Sub-Select AND Left-Outer join?

  • Unable to find standard libraries when compiling Objective-C using GNUstep on Windows

    - by Jason Roberts
    I just installed GNUstep on my Windows XP machine and I'm attempting to compile the following Objective-C Hello World program from the command line: #import <Foundation/Foundation.h> int main(int argc, const char *argv[]) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSLog(@"Hello world\n"); [pool drain]; return 0; } When I try to compile the program from the command line like so gcc hello.m -o hello I end up getting the following error hello.m:1:34: Foundation/Foundation.h: No such file or directory Is there something I need to do order to inform the compiler of where the standard Objective-C libraries are located?

  • C# System.Threading.Timer and its state object

    - by Captain NedD
    I am writing a C# program that uses System.Threading.Timer to timeout on a UDP socket ReceiveAsync call. My program polls a remote device, sending a UDP packet and expecting one in return. I use the timer in one shot mode calling Timer.Change every time I want a new timeout period. For every occurance of a timeout I'd like the timeout handler to have a different piece of information. If I change the object I pass to the Timer on creation it doesn't seem to change when the handler executes. Is the only way to do this to destroy the timer and create a new one? Thanks,

  • Why won't Windows Installer use the UI in the .msi file during removal?

    - by billmcc
    Has anyone been able to get Windows Installer to use the InstallUISequence table during removal? I started with an MSI file produced by the Visual Studio msi builder, decompiled it into WiX source code and handcrafted it, but I cannot get the installer to use my UI during removal. It insists on using a default UI provided by Windows Installer. I have also analyzed several MSI files, and I have been unable to find one where Windows Installer will use the provided UI during removal. I captured the msiexec logs during removal, and sure enough, Windows Installer appears to be ignoring the InstallUISequence table. It seems that msiexec runs with minimal UI during removal. If I specify the /qf switch (use full UI) during removal, then Windows Installer does take the UI from the .msi file. However, this doesn't help the regular user, because she won't do the removal from msiexec. Does anyone know of a way to convince Windows Installer to use the UI in the MSI file by default?

  • DAL without web2py

    - by Jay
    I am using web2py to power my web site. I decided to use the web2py DAL for a long running program that runs behind the site. This program does not seem to update its data or the database (sometimes). from gluon.sql import * from gluon.sql import SQLDB from locdb import * # contains # db = SQLDB("mysql://user/pw@localhost/mydb", pool_size=10) # db.define_table('orders', Field('status', 'integer'), Field('item', 'string'), # migrate='orders.table') orderid = 20 # there is row with id == 20 in table orders #when I do db(db.orders.id==orderid).update(status=6703) db.commit() It does not update the database, and a select on orders with this id, shows the correct data. In some circumstances a "db.rollback()" after a commit seems to help. Very strange to say the least. Have you seen this, more importantly do you know the solution? Jay

  • F# PowerPack 2.0.0.0 issue: The task ..."…\fslex.exe" is invalid

    - by Roman Kuzmin
    I have upgraded F# PowerPack today to the latest 2.0.0.0 and tried to rebuild the MiniCalc sample from here: http://achrissmith.blogspot.com/2010/04/fslex-and-fsyacc-examples-updated.html If I build it in VS 2010 it fails with the message: C:\Program Files\MSBuild\FSharp\1.0\FSharp.PowerPack.targets(32,3): error MSB6004: The specified task executable location "C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\fslex.exe" is invalid. If I build it from the command line by MSBuild it complains about missing C:\Windows\Microsoft.NET\Framework\v4.0.30319\fslex.exe The problem is kind of “fixed” if I copy fslex and fsyacc to that both directories, so after that I can build from the command line and from VS 2010. But it does not look like a right way to solve the problem. What is the right way? EDIT: The same issue is true for the PowerPack sample from sources: May2010\workyard\tests\LexAndYaccMiniProject. Now (after the trick I have done) it is built fine, too.

  • Disable eclipselink caching and query caching - not working?

    - by James
    I am using eclipselink JPA with a database which is also being updated externally to my application. For that reason there are tables I want to query every few seconds. I can't get this to work even when I try to disable the cache and query cache. For example: EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("default"); EntityManager em = entityManagerFactory.createEntityManager(); MyLocation one = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); Thread.sleep(10000); MyLocation two = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); System.out.println(one.getCapacity() + " - " + two.getCapacity()); Even though the capacity changes while my application is sleeping the println always prints the same value for one and two. I have added the following to the persistence.xml <property name="eclipselink.cache.shared.default" value="false"/> <property name="eclipselink.query-results-cache" value="false"/> I must be missing something but am running out of ideas.

  • Best way to detect integer overflow in C/C++

    - by Chris Johnson
    I was writing a program in C++ to find all solutions of a^b = c (a to the power of b), where a, b and c together use all the digits 0-9 exactly once. The program looped over values of a and b, and ran a digit-counting routine each time on a, b and a^b to check if the digits condition was satisfied. However, spurious solutions can be generated when a^b overflows the integer limit. I ended up checking for this using code like: unsigned long b, c, c_test; ... c_test=c*b; // Possible overflow if (c_test/b != c) {/* There has been an overflow*/} else c=c_test; // No overflow Is there a better way of testing for overflow? I know that some chips have an internal flag that is set when overflow occurs, but I've never seen it accessed through C or C++.

  • Show CMFCRibbonStatusBar

    - by praetorian20
    Hi, I'm creating a simple SDI app using the new VS2008 service pack. I added ribbon support but all I want on the ribbon are the Open & Close buttons. I commented out all the code that creates the other default buttons and categories but doing this also gets rid of the status bar (CMFCRibbonStatusBar). I can't find what member function is called when I click the checkbox that displays the statusbar in the default generated code. I've tried the following but it doesn't work: m_wndStatusBar.ShowWindow( SW_SHOWNORMAL ); How do I have the status bar showing without having to have the 'Home' category and 'View' panel (with the 'Show status bar' checkbox) being generated? Thanks, Ashish.

  • Unwanted SDL_QUIT Event on mouseclick.

    - by Anthony Clever
    I'm having a slight problem with my SDL/Opengl code, specifically, when i try to do something on a mousebuttondown event, the program sends an sdl_quit event to the stack, closing my application. I know this because I can make the program work (sans the ability to quit out of it :| ) by checking for SDL_QUIT during my event loop, and making it do nothing, rather than quitting the application. If anyone could help make my program work, while retaining the ability to, well, close it, it'd be much appreciated. Code attached below: #include "SDL/SDL.h" #include "SDL/SDL_opengl.h" void draw_polygon(); void init(); int main(int argc, char *argv[]) { SDL_Event Event; int quit = 0; GLfloat color[] = { 0.0f, 0.0f, 0.0f }; init(); glColor3fv (color); glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0); draw_polygon(); while(!quit) { while(SDL_PollEvent( &Event )) { switch(Event.type) { case SDL_MOUSEBUTTONDOWN: for (int i = 0; i <= sizeof(color); i++) { color[i] += 0.1f; } glColor3fv ( color ); draw_polygon(); case SDL_KEYDOWN: switch(Event.key.keysym.sym) { case SDLK_ESCAPE: quit = 1; default: break; } default: break; } } } SDL_Quit(); return 0; } void draw_polygon() { glBegin(GL_POLYGON); glVertex3f (0.25, 0.25, 0.0); glVertex3f (0.75, 0.25, 0.0); glVertex3f (0.75, 0.75, 0.0); glVertex3f (0.25, 0.75, 0.0); glEnd(); SDL_GL_SwapBuffers(); } void init() { SDL_Init(SDL_INIT_EVERYTHING); SDL_SetVideoMode( 640, 480, 32, SDL_OPENGL ); glClearColor (0.0, 0.0, 0.0, 0.0); glMatrixMode( GL_PROJECTION | GL_MODELVIEW ); glLoadIdentity(); glClear (GL_COLOR_BUFFER_BIT); SDL_WM_SetCaption( "OpenGL Test", NULL ); } If it matters in this case, I'm compiling via the included compiler with Visual C++ 2008 express.

  • why do game engines prefer static libraries over dynamic link libraries

    - by numerical25
    I've been reading a few gaming books. And they always prefer to create the engine as a static library over dynamic link. I am new to c++ so I am not highly knowledge when it comes to static libraries and dynamic link libraries. All I know is static libraries increase the size of your program, where DLL link libraries are loaded as you need them within your program. [edit] I've played games where it almost seemed they used DLL's to load in sound, lighting, and what not all individually. as the level was loading up. cause you don't necessarily need that when your at the game menu.

  • NetBeans behaves differently if project is run via "Run Project" or build.xml>run

    - by Rogach
    I slightly modified the build-impl.xml file of my NetBeans project. (Specifically, I made it to insert build time into program code). If I run project via build.xml "run" target, I get behavior I expect - the program displays build time and date. But if I run project using standard (and most obvious, used it always) button "Run Main Project", I get totally another result (no build date). Moreover, if I insert any code into build.xml, I still get result if I run the target explicitly and no result if it is run simply by NetBeans. And this leads me to conclusion, that this button uses another method to run my application. My question is: what does that button do? What method does it call? And can it be configured to run the needed target of make file?

  • Reading a POP3 server with only TcpClient and StreamWriter/StreamReader[SOLVED]

    - by WebDevHobo
    I'm trying to read mails from my live.com account, via the POP3 protocol. I've found the the server is pop3.live.com and the port if 995. I'm not planning on using a pre-made library, I'm using NetworkStream and StreamReader/StreamWriter for the job. I need to figure this out. So, any of the answers given here: http://stackoverflow.com/questions/44383/reading-email-using-pop3-in-c are not usefull. It's part of a larger program, but I made a small test to see if it works. Eitherway, i'm not getting anything. Here's the code I'm using, which I think should be correct. EDIT: this code is old, please refer to the second block problem solved. public Program() { string temp = ""; using(TcpClient tc = new TcpClient(new IPEndPoint(IPAddress.Parse("127.0.0.1"),8000))) { tc.Connect("pop3.live.com",995); using(NetworkStream nws = tc.GetStream()) { using(StreamReader sr = new StreamReader(nws)) { using(StreamWriter sw = new StreamWriter(nws)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); while(temp != ".") { temp += sr.ReadLine(); } } } } } Console.WriteLine(temp); } Visual Studio debugger constantly falls over tc.Connect("pop3.live.com",995); Which throws an "A socket operation was attempted to an unreachable network 65.55.172.253:995" error. So, I'm sending from port 8000 on my machine to port 995, the hotmail pop3 port. And I'm getting nothing, and I'm out of ideas. Second block: Problem was apparently that I didn't write the quit command. The Code: public Program() { string str = string.Empty; string strTemp = string.Empty; using(TcpClient tc = new TcpClient()) { tc.Connect("pop3.live.com",995); using(SslStream sl = new SslStream(tc.GetStream())) { sl.AuthenticateAsClient("pop3.live.com"); using(StreamReader sr = new StreamReader(sl)) { using(StreamWriter sw = new StreamWriter(sl)) { sw.WriteLine("USER " + user); sw.Flush(); sw.WriteLine("PASS " + pass); sw.Flush(); sw.WriteLine("LIST"); sw.Flush(); sw.WriteLine("QUIT "); sw.Flush(); while((strTemp = sr.ReadLine()) != null) { if(strTemp == "." || strTemp.IndexOf("-ERR") != -1) { break; } str += strTemp; } } } } } Console.WriteLine(str); }

  • How can I do something ~after~ an event has fired in C#?

    - by Siracuse
    I'm using the following project to handle global keyboard and mouse hooking in my C# application. This project is basically a wrapper around the Win API call SetWindowsHookEx using either the WH_MOUSE_LL or WH_KEYBOARD_LL constants. It also manages certain state and generally makes this kind of hooking pretty pain free. I'm using this for a mouse gesture recognition software I'm working on. Basically, I have it setup so it detects when a global hotkey is pressed down (say CTRL), then the user moves the mouse in the shape of a pre-defined gesture and then releases global hotkey. The event for the KeyDown is processed and tells my program to start recording the mouse locations until it receives the KeyUp event. This is working fine and it allows an easy way for users to enter a mouse-gesture mode. Once the KeyUp event fires and it detects the appropriate gesture, it is suppose to send certain keystrokes to the active window that the user has defined for that particular gesture they just drew. I'm using the SendKeys.Send/SendWait methods to send output to the current window. My problem is this: When the user releases their global hotkey (say CTRL), it fires the KeyUp event. My program takes its recorded mouse points and detects the relevant gesture and attempts to send the correct input via SendKeys. However, because all of this is in the KeyUp event, that global hotkey hasn't finished being processed. So, for example if I defined a gesture to send the key "A" when it is detected, and my global hotkey is CTRL, when it is detected SendKeys will send "A" but while CTRL is still "down". So, instead of just sending A, I'm getting CTRL-A. So, in this example, instead of physically sending the single character "A" it is selecting-all via the CTRL-A shortcut. Even though the user has released the CTRL (global hotkey), it is still being considered down by the system. Once my KeyUp event fires, how can I have my program wait some period of time or for some event so I can be sure that the global hotkey is truly no longer being registered by the system, and only then sending the correct input via SendKeys?

  • Relative Resizing of Forms in C#

    - by xarzu
    What is the magic that makes components cling to the edges of a form? I had thought that one must use the resize event of the form and them force each element in the form to resize. But then I saw some sample code which, even when I am editing the form, the elements seem to adhere to a percentage of the space they take up in the form rather than a set diminsion. In other words, when I am editing the form and resizing it, the panels and the parts inside the form bend their shape such that the edges remain a few pixels from the edges. But in my own program I have not been able to find where I can duplicate this feature. When I run my program, this (http://i67.photobucket.com/albums/h292/Athono/microsoft/001.jpg) goes to this (http://i67.photobucket.com/albums/h292/Athono/microsoft/002.jpg)

  • Good projects to learn OCaml and F#

    - by Yin Zhu
    After learning the basic syntax, reading some non-trivial code is a fast way to learn a language. We can also learn how to design a library/software during reading others' code. I have following lists. A Chess program in OCaml by Tomek Czajka. Hal Daumé has written several machine learning libraries in Ocaml. Including decision trees, logistic regression and SVM. All of them are near-production-quality code. A Chess Game Analysis program in F# in Microsoft Research. The above three are my favorites. Will you suggest some other sources? General purpose open source software are good, specialized open source like the three I list here are even more welcome.

  • python metaprogramming

    - by valya
    I'm trying to archive a task which turns out to be a bit complicated since I'm not very good at Python metaprogramming. I want to have a module locations with function get_location(name), which returns a class defined in a folder locations/ in the file with the name passed to function. Name of a class is something like NameLocation. So, my folder structure: program.py locations/ __init__.py first.py second.py program.py will be smth with with: from locations import get_location location = get_location('first') and the location is a class defined in first.py smth like this: from locations import Location # base class for all locations, defined in __init__ (?) class FirstLocation(Location): pass etc. Okay, I've tried a lot of import and getattribute statements but now I'm bored and surrender. How to archive such behaviour?

  • SQL Server: Database stuck in "Restoring" state

    - by Ian Boyd
    i backed up a data: BACKUP DATABASE MyDatabase TO DISK = 'MyDatabase.bak' WITH INIT --overwrite existing And then tried to restore it: RESTORE DATABASE MyDatabase FROM DISK = 'MyDatabase.bak' WITH REPLACE --force restore over specified database And now the database is stuck in the restoring state. Some people have theorized that it's because there was no log file in the backup, and it needed to be rolled forward using: RESTORE DATABASE MyDatabase WITH RECOVERY Except that, of course, fails: Msg 4333, Level 16, State 1, Line 1 The database cannot be recovered because the log was not restored. Msg 3013, Level 16, State 1, Line 1 RESTORE DATABASE is terminating abnormally. And exactly what you want in a catastrophic situation is a restore that won't work. The backup contains both a data and log file: RESTORE FILELISTONLY FROM DISK = 'MyDatabase.bak' Logical Name PhysicalName ============= =============== MyDatabase C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase.mdf MyDatabase_log C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase_log.LDF

  • django-admin: creating,saving and relating a m2m model

  • Where is PostSharp.Public 1.5 DLL ?

    - by jfneis
    Fellows, I'm going crazy with looks like a really stupid problem. I'm trying to build a simple example using PostSharp as a log AOP utility. I've not installed PostSharp, and I don't want to, I want to reference the necessaries DLLs, change my .csproj and see everything working. Change the project and add references was kind of easy, byt just after adding the LogAttribute to a method I got two errors: Error 1 'Log4PostSharp.LogAttribute' is not an attribute class C:\Dev\LogWithPostsharp\LogWithPostsharpCmd\Program.cs 17 10 LogWithPostsharpCmd Error 2 The type 'PostSharp.Extensibility.MulticastAttribute' is defined in an assembly that is not referenced.

C:\Dev\LogWithPostsharp\LogWithPostsharpCmd\Program.cs 18 22 LogWithPostsharpCmd The first error really looks like consequence of the second, but here is the deal: the PostSharp.Public.* simply doesn't exist in the downloaded .zip. Is there something that I'm not getting? Thank you in advance. Filipe
