  • What groupware/collaboration system to choose?

    - by Ivan
    I am looking for a good (stable enough, intuitive enough, and the more technologically modern and advanced - the better) free PHP-based online groupware/collaboration system. 100% UTF-8 is a requirement. OOP-style code is an advantage. And collaborative mindmapping would be a cool feature to have. The team is of ~20 people. Any suggestions?

  • Please recommend a Java profiler

    - by Yuval F
    I am looking for the Java equivalent of gprof. I did a little Java profiling using System.getCurrentMillis(), and saw several GUI tools which seem too much. A good compromise could be a text-based Java profiler, preferably free or low-cost, which works in either Windows XP or Linux.

  • How to auto-sync Header in Visual Studio ?

    - by fk2
    Do you know if there is a build-in feature or free add-in for Microsoft Visual Studio 2008 that easily generates C-Headers and keeps them in sync with their .c counterparts? I have already looked at Visual Assist X, but I'm not really willing to pay money at the moment.

  • CGImageCreateWithMask with an image as a mask

    - by Peyman
    Hi I am trying to use an image (painted as Core Graphics) to create a mask. What I am doing is this 1. creating a Core Graphics path CGContextSaveGState(context); CGContextBeginPath(context); CGContextMoveToPoint(context,circleCenter.x,circleCenter.y); //CGContextSetAllowsAntialiasing(myBitmapContext, YES); CGContextAddArc(context,circleCenter.x, circleCenter.y,circleRadius,startingAngle, endingAngle, 0); // 0 is counterclockwise CGContextClosePath(context); CGContextSetRGBStrokeColor(context,1.0,0.0,0.0,1.0); CGContextSetRGBFillColor(context,1.0,0.0,0.0,0.2); CGContextDrawPath(context, kCGPathFillStroke); 2. then I'm saving the context that has the path just painted CGImageRef pacmanImage = CGBitmapContextCreateImage (context); 3. restoring the context CGContextRestoreGState(context); CGContextSaveGState(context); 4. creating a 1 bit mask (which will provide the black-white mask) bitsPerComponent = 1; bitsPerPixel = bitsPerComponent * 1 ; bytesPerRow = (CGImageGetWidth(imgToMaskRef) * bitsPerPixel); mask = CGImageCreate(CGImageGetWidth(imgToMaskRef), CGImageGetHeight(imgToMaskRef), bitsPerComponent, bitsPerPixel, bytesPerRow, greyColorSpace, kCGImageAlphaNone, CGImageGetDataProvider(pacmanImage), NULL, //decode YES, //shouldInterpolate kCGRenderingIntentDefault); 5. masking the imgToMaskRef (which is a CGImageRef imgToMaskRef =imgToMask.CGImage;) with the mask just created imageMaskedWithImage = CGImageCreateWithMask(imgToMaskRef, mask); CGContextDrawImage(context,imgRectBox, imageMaskedWithImage); CGImageRef maskedImageFinal = CGBitmapContextCreateImage (context); returning the maskedImageFinal to the caller of this method (as wheelChoiceMadeState, which is a CGImageRef) who then updates the CALayer contents property with the image theLayer.contents = (id) wheelChoiceMadeState; the problem I am seeing is that the mask does not work properly and looks very strange indeed. I get strange patterns across the path painted by the Core Graphics. My hunch is there is something with CGImageGetDataProvider() but I am not sure. Any help would be appreciated thank you

  • ActiveX control loading but not activating correctly (only when using in Reg Free COM)

    - by embnut
    I have an ActiveX control (created using C#) that I am adding to a form in Visual FoxPro using late binding. It works without problems when I register the control. I want to use reg free COM and created necessary manifest files. Now it load and displays in an inactive state until I double click or programatically activate it. I don't think it has anything to do with the reg free com manifest files. However is there something I need to do to set it up before/after making the late binding call AddObject()? this.AddObject('OleControl1', 'oleControl', 'SomeCompany.SomeOleControl') When I check the OleTypeAllowed Property of the OleControl created by AddObject() it is 1 (Embedded OLE object) instead of -2 (ActiveX object). So the OleControl got instantiated to the wrong type. I also tried the following: DEFINE(d) a subclass of OleControl and set the property OleTypeAllowed = -2. Used late binding to load the control. It did not work as required. The OleTypeAllowed came back as 1 Registered the ActiveX control. Added the ActiveX control to the project as a subclass using the visual editor. Unregistered the control. Used late binding to load the control. It did not work as required. The OleTypeAllowed came back as 1. Is it possible to load the OleControl as a ActiveX control? Any input from VB that I can convert to FoxPro would also be appreciated.

  • detecting double free object, release or not release ...

    - by mongeta
    Hello, If we have this code in our interface .h file: NSString *fieldNameToStoreModel; NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; DataEntered *dataEntered; In our implementation file .m we must have: - (void)dealloc { [fieldNameToStoreModel release]; [fetchedResultsController release]; [managedObjectContext release]; [dataEntered release]; [super dealloc]; } The 4 objects are assigned from a previous UIViewController, like this: UIViewController *detailViewController; detailViewController = [[CarModelSelectViewController alloc] initWithStyle:UITableViewStylePlain]; ((CarModelSelectViewController *)detailViewController).dataEntered = self.dataEntered; ((CarModelSelectViewController *)detailViewController).managedObjectContext = self.managedObjectContext; ((CarModelSelectViewController *)detailViewController).fieldNameToStoreModel = self.fieldNameToStoreModel; [self.navigationController pushViewController:detailViewController animated:YES]; [detailViewController release]; The objects that now live in the new UIViewController, are the same as the previous UIViewController, and I can't release them in the new UIViewController ? The problems is that sometimes, my app crashes when I leave the new UIViewController and go to the previous one, not always. Normally the error that I'm getting is a double free object. I've used the malloc_error_break but I'm still not sure wich object is. Sometimes I can go from the previous UIViewController to the next one and come back 4 or 5 times, and the double free object appears. If I don't release any object, all is working and Instruments says that there are no memory leaks ... So, the final question, should I release those objects here or not ? Thanks, m.

  • Choosing an installer product that is free and will download/install the .NET Framework

    - by Coder7862396
    I'm currently using the Visual Studio Installer (Setup Project) in Visual Studio 2010 as the installer for MyProgram. It has some quirky bugs and is not very customizable so I would like to switch to another installer product. Here are my requirements: Must be free (and licensed for commercial use) Must install the Windows Installer 3.1 and .NET Framework 4.0 if the client doesn't have them The installer will download them if they are not available The code for detecting the .NET Framework and downloading it must be written by Microsoft (I do not want to have to update hard-coded URLs and registry keys in the future). I know that the Windows SDK includes a setup bootstrap that does this (C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper) In the future, when .NET Framework 5 is released and MyProgram uses it, no installer code will need to be changed, the updated installer product should see that MyProgram now uses the .NET Framework version 5 and will install that Here are my current choices: Visual Studio Installer: Automatically detects/downloads/installs Windows Installer and .NET Framework using a bootstrapper Setup.exe (Good!) Limited/buggy functionality (Uninstall shortcuts in the Start Menu cause empty folders to be left behind during uninstall, asking the user if they want a desktop shortcut requires a lot of work, etc.) NSIS: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLS, etc. Inno Setup: Doesn't natively support the .NET Framework so adding it as a prerequisite requires excessive coding, hardcoded URLs, etc. WiX: Steep learning curve... not sure if I want to spend weeks learning it only to find out that it has the same uninstall problem as the Visual Studio Installer (because they both use MSI files) InstallShield LE 2010: Downloading it requires me to setup a fake email account to register just to download it. Then once it is installed it has to contact the company's servers and transmit some private information to them before I'm even allowed to try the free version. This is the most insidious form of DRM that there is and I will not accept it.

  • Difference between an LL and Recursive Descent parser?

    - by Noldorin
    I've recently being trying to teach myself how parsers (for languages/context-free grammars) work, and most of it seems to be making sense, except for one thing. I'm focusing my attention in particular on LL(k) grammars, for which the two main algorithms seem to be the LL parser (using stack/parse table) and the Recursive Descent parser (simply using recursion). As far as I can see, the recursive descent algorithm works on all LL(k) grammars and possibly more, whereas an LL parser works on all LL(k) grammars. A recursive descent parser is clearly much simpler than an LL parser to implement, however (just as an LL one is simply than an LR one). So my question is, what are the advantages/problems one might encounter when using either of the algorithms? Why might one ever pick LL over recursive descent, given that it works on the same set of grammars and is trickier to implement? Hopefully this question makes some amount of sense. Sorry if it doesn't - I blame my the fact that this entire subject is almost entirely new to me.

  • QT: Scroll widget that renders directly to the DC

    - by shoosh
    I'm trying to create a widget which paints directly to the windows Device Context by calling getDC() and painting an HBITMAP to it. The widget I'm painting resides inside a scroll widget. I've implemented the paintEvent() and it does seem to paint but immediatly after painting the widget gets painted over again with a blank gray color. I've tried setting WA_PaintOnScreen and Qt::WA_NoSystemBackground but none of those help. In theory this should be possible since this is basically how the GLWidget works. What am I missing?

  • ASP.NET Error when referencing a code-behind variable

  • Reverting CoreData data

    - by ndg
    I have an NSTableView which is populated via a CoreData-backed NSArrayController. Users are able to edit any field they choose within the NSTableView. When they select the rows that they have modified and press a button, the data is sent to a third-party webservice. Provided the webservice accepts the updated values, I want to commit those values to my persistent store. If, however, the webservice returns an error (or simply fails to return), I want the edited fields to revert to their original values. To complicate matters, I have a number of other editable controls, backed by CoreData, which do not need to resort to this behaviour. I believe the solution to this problem revolves around the creation of a secondary Managed Object context, which I would use only for values edited within that particularly NSTableView. But I'm confused as to how the two MOC would interact with each other. What's the best solution to this problem?

  • How to create a generic C free function .

    - by nomemory
    I have some C structures related to a 'list' data structure. They look like this. struct nmlist_element_s { void *data; struct nmlist_element_s *next; }; typedef struct nmlist_element_s nmlist_element; struct nmlist_s { void (*destructor)(void *data); int (*cmp)(const void *e1, const void *e2); unsigned int size; nmlist_element *head; nmlist_element *tail; }; typedef struct nmlist_s nmlist; This way I can have different data types being hold in "nmlist_element-data" . The "constructor" (in terms of OOP) has the following signature: nmlist *nmlist_alloc(void (*destructor)(void *data)); Where "destructor" is specific function that de-allocated "data" (being hold by the nmlist_element). If I want to have a list containing integers as data, my "destructor" would like this: void int_destructor(void *data) { free((int*)data); } Still i find it rather "unfriendly" for me to write a destructor functions for every simple primitive data type. So is there a trick to write something like this ? (for primitives): void "x"_destructor(void *data, "x") { free(("x" *)data); } PS: I am not a macro fan myself, and in my short experience regarding C, i don't use them, unless necessary.

  • Using Hibernate with MS ACCESS 2007 Database (Free JDBC Driver)

    - by Quentin T.
    1. I want to do a reverse engineering action with the Hibernate plugin of Eclipse on a MS Access 2007 Database. I'm forced to use a existing MS Access 2007 db. A easy solution is to buy the HXTT. But I want to use a free driver to do my work. So I tried to apply this post : http://www.programmingforfuture.com/2011/06/how-to-use-ms-access-with-hibernate.html (That uses the SQL Server dialect and the driver sun.jdbc.odbc.JdbcOdbcDriver) Unfortunately I have an error that nobody seems to have been on the internet: Exception while generating code Reason : org.hibernate.exception.GenericJDBCException: Error while reading primary key meta data for `c:/myaccessdb.mdb`.TableTest1 I have try to change the primary key on my MS Access DB (deleting all primary key) or to try the reverse engineering on a MS ACCESS with only one table without primary key, but I got all times the problems. 2. The purpose of my job is to transfer daily (weekly) an Oracle 11g database with data from an existing database MS ACCESS 2007. And I thought to use a procedure (Hibernate EJB) Java to be launched automatically every week to do the data transfer. Is this is the best solution ? Configuration : sun.jdbc.odbc.JdbcOdbcDriver v??? Hibernate v3.4 Eclipse ps: If you are a HXTT developer or seller please be indulgent with my post ;). Making money by making people believe that you help, it's bad ! A solution is to use Derby Client driver, as the solution in the post: Does anyone know if Hibernate and java will work effectively with Access? But a clarification of the answer of Rich Seller is required. Could you explain your answer and explain your configuration (hibernate.cfg.xml, persistence.xml and what URL you use in the property name="hibernate.connection.url") without using paying HXTT driver but with the free Derby driver.

  • Jetty 7 will not allow me to customize a session cookie path

    - by Bob Obringer
    Using Jetty 7.0.2, I am unable to set a custom session cookie path. I am hosting multiple sites on the same server using apache to proxy requests to the proper context. (replaced http as htp as stackoverflow thinks my multiple links might be spam) <VirtualHost *:80> ServerName context.domain.com ProxyRequests On ProxyPreserveHost Off <Proxy *:80> Order deny,allow Allow from 127.0.0.1 </Proxy> ProxyPass / htp://localhost:8080/context/ ProxyPassReverse / htp://localhost:8080/context/ <Location /> Order allow,deny Allow from all </Location> </VirtualHost> Jetty is running on the same server on port 8080 and my context is available @ /context The user accesses the application @ htp://context.domain.com but jetty is setting the path for the session cookie @ /context. This prevents the browser from accessing the cookie since the the actual path to the context is not being used. I need to override Jetty's default setting to set the cookie for the context, and set the path at the root ( / ). In my Jetty's webdefault.xml I have the following, which is partially working: <context-param> <param-name>org.eclipse.jetty.servlet.SessionCookie</param-name> <param-value>CustomCookieName</param-value> </context-param> <context-param> <param-name>org.eclipse.jetty.servlet.SessionPath</param-name> <param-value>/</param-value> </context-param> The cookie is properly set with a custom name, but it is NOT setting the SessionPath. No matter what I set the value to... it refuses to set a cookie at any path but /context. This has been driving me crazy so any help would be greatly appreciated.

  • Django template tag basic question

    - by ninja123
    It looks like this template tag works like a charm for most people: http://blog.localkinegrinds.com/2007/09/06/digg-style-pagination-in-django/ For some reason I get this error: Caught an exception while rendering: 'is_paginated' I use this template tag in my template like so: {% load digg_paginator %} {% digg_paginator %} Where digg_paginator.py is in my app/templatetags folder and the included template context digg_paginator.html is in my app/templates folder. The queryset that needs pagination is called 'destinations'. If i just specify {% digg_paginator %}, how does it know what variable to paginate?? I feel I am missing something important here or just plain stupid :P Someone please help, or explain to me how this should be done. Thanks

  • open program once with multiple files as arguments from explorer

    - by Jonathan
    I have a program that works when, a file is opened with it using the right click menu in explorer. But if I select multiple files and then right click and open with my program then it opens multiple instances of my program, instead of just passing the multiple files as arguments to a single instance. The program is written in vb.net but is not a windows form, it is just a module, so I can to tick the Single instance option in the properties in Visual Studio. So how do I open multiple files from explorer context menu in a single instance.
