  • Portable Device Path on Windows

    - by Ripei
    Hey guys I actually got an Windows/Java Question. I've got an plugged in Device which I want to access via Java. Normaly u can access an e.g. USB-Stick via the Drive letter... but this Tablet is displayed by Windows as an "Portable Device"... which means, that the Path is sth. like "Computer\Archos 5S" and there is no Drive letter. I want to access a File on this Device via Java, but I am not able to figure out the correct Path to it. There is a similar Question out there, but without a productive answear. Or is there an other way to access this Device via Java? thanks in advance ripei

  • Trouble using opaque pointers in Objective C++

    - by morgancodes
    The answer to this quesion explains that opaque pointers are a good way to include C++ member variables in an Objective C++ header. I'm getting compile errors when trying to follow the example. Here's the relevant code from my header, with the corresponding compiler errors shown as comments: struct ADSR_opaque; // error: forward declaration of 'struct ADSR_opaque' @interface LoopyPulser : NSObject{ float _pulseRate; UInt32 tickInterval; UInt32 step; InMemoryAudioFile * audioFilePlayer; ADSR_opaque* env; // error: expected specifier-qualifier-list before 'ADSR_opaque' Pattern * pattern; float loopLengthRatio; float volume; } Is there something simple I'm doing wrong here?

  • Implementing Projectile Motion

    - by DMan
    I've scored the internet for sources and have found a lot of useful information, but they are math sites trying to tell me how to solve what angle an object has to be at to reach y location. However, I'm trying to run a simulation, and haven't found any solid equations that can be implemented to code to simulate a parabolic curve. Can those with some knowledge of physics help me on this?

  • Custom Cocoa Framework and a problem using it

    - by happyCoding25
    Hello, I made a custom cocoa framework just to experiment and find the best way to make one but ran in to a problem using it. The framework project builds and compiles just fine, but when I use it in an xcode project I get the error, 'LogTest' undeclared. The name of the framework is LogTest Heres the code to my app that uses the framework: AppDelegate.h: #import <Cocoa/Cocoa.h> #import <LogTest/LogTest.h> @interface TestAppDelegate : NSObject <NSApplicationDelegate> { NSWindow *window; } @property (assign) IBOutlet NSWindow *window; @end AppDelegate.m: #import "TestAppDelegate.h" @implementation TestAppDelegate @synthesize window; - (void)awakeFromNib { [LogTest logStart:@"testing 123":@"testing 1234"]; //This is the line where the error occurs } @end Framework Code........ LogTest.h: #import <Cocoa/Cocoa.h> #import "Method.h" @protocol LogTest //Not sure if this is needed I just wanted a blank header @end Method.h: #import <Cocoa/Cocoa.h> @interface Method : NSObject { } + (void)logStart:(NSString *)test:(NSString *)test2; @end Method.m: #import "Method.h" @implementation Method + (void)logStart:(NSString *)test:(NSString *)test2 { NSLog(test); NSLog(test2); } @end If anyone knows why I am getting this error please reply. Thanks for any help

  • Is learning the Caché database hard coming from relational databases and object oriented programming

    - by Edelcom
    I am currently running the local version of Caché on my system in order to determine if I can (and will) take on a new possible project. The current project uses Delphi 7 as a front end calling a Caché dll where the business logic is stored in the database. I have a background of Sqlserver and Firebird (and before Access and Paradox) as databases. I use Delphi 7 for 95% of my Windows development, so I know about object programming. I would like to recieve opinions from persons having used Caché and either SqlServer, Firebird or Oracle and having developed in Delphi (or C++ or C# - an object oriented language). I have read the pro's and con's from other questions, but I am not asking for this, I need input from Caché developers. Thanks in advance.

  • Is this a good KVO-compliant way to model a mutable to-many relationship?

    - by andyvn22
    Say I'd like a mutable, unordered to-many relationship. For internal optimization reasons, it'd be best to store this in an NSMutableDictionary rather than an NSMutableSet. But I'd like to keep that implementation detail private. I'd also like to provide some KVO-compliant accessors, so: - (NSSet*)things; - (NSUInteger)countOfThings; - (void)addThings:(NSSet*)someThings; - (void)removeThings:(NSSet*)someThings; Now, it'd be convenient and less evil to provide accessors (private ones, of course, in my implementation file) for the dictionary as well, so: @interface MYClassWithThings () @property (retain) NSMutableDictionary* keyedThings; @end This seems good to me! I can use accessors to mess with my keyedThings within the class, but other objects think they're dealing with a mutable, unordered (, unkeyed!) to-many relationship. I'm concerned that several things I'm doing may be "evil" though, according to good style and Apple approval and whatnot. Have I done anything evil here? (For example, is it wrong not to provide setThings, since the things property is supposedly mutable?)

  • How popular is WPF as a technology?

    - by Vaibhav
    I had a discussion with some colleagues mentioning that there are not too many projects that we do which make use of WPF for creating UI for a windows application (we almost always use Windows Forms instead). Are your experiences the same - i.e. there is not too much adoption of this technology? Why do you think that is? And will we have a time when we see much more of WPF?

  • How to implement SVN pre-commit hook with best performance?

    - by mliebelt
    We have the following tools in place: Subversion (Version 1.5.9) Polarion (version 3.2.2) Polarion is based on Subversion, so on every action that changes anything (which is often the case), Polarion will use a Subversion commit to change anything. All things are currently stored in one and only one repository, so every commit of every user (some 100-200 on the same repository) will trigger the pre-commit hook. So what is the best strategy to provide pre-commit hooks that will trigger only for some, but not all projects run as fast as possible, because every pre-commit hook will block all other commits. We have tried to implement pre-commit hooks with Java (using SVNKit), but this will start on every commit a Java VM. So any ideas how to implement that nicely?

  • How do I convert an INT into HH:mm:ss using SSRS 2005

    - by user293249
    Ok I need to display total talk time of an agent that is coming into SRSS 2005 from SQL 2005 as an INT. For the life of me I cannot figure out what combination of expression editing or format editing I need to use. For the detail portion I can use: =DATEADD("s", SUM(Fields!Talk_Time.Value), CDate("00:00")) And it will return: 1/1/0001 12:00:14 AM Now I can use =LEFT(DATEADD("s", SUM(Fields!Talk_Time.Value), CDate("00:00")),8) Which will return: 12:00:14 But really what I need is: 00:00:14 Please help!

  • retrieve Scrollbar position with javascript

    - by Paul
    I know how to do this in flash, but completely lost about regular html. I'm trying to detect the position of the browser scrollbar with Javascript to decide where abouts in the page the current view is. My guess is that I'd have to detect where the thumb on the track is, and then the height of the thumb as a percentage of the total height of the track. Am I over-complicating it, or does Javascript offer an easier solution than that? Any ideas code-wise. Thanks.

  • solution for COMET and PHP

    - by codemaker
    Is there a real solution for COMET AND PHP combination? Basically, I've come to a point that I need to update a user home page periodically whenever there is new data in the database. As far as I understand, I need to open a persistent connection between my server and my clients browsers to update the contents of their home page as soon as new info. available without dedicating a lot of resources but I had no luck finding anything clear about this issue. I read many articles suggests that PHP is not a good language to implement COMET. My web application is completely programmed in PHP and I don't want to learn another language but if I'm forced to, Would you suggest a good language to start with? Do you think that I can program an interface just to handle this issue? Thanks in advance.

  • committing to a branch that's not checked out

    - by intuited
    I'm using git to version my home directories on a couple different machines. I'd like for them to each use separate branches and both pull from a common branch. So most commits should be made to that common branch, unless something specific to that machine is being committed, in which case the commit should go to the checked out, machine-specific branch. Switching branches is clearly not a very good option in this case. It's mentioned in this post that what I want to do is impossible, but I found that answer to be rather blunt and to perhaps not take into account the possibility of using the plumbing commands. Unfortunately I don't have enough reputation to comment on that thread. I rather suspect that there is some way to do this and am hoping to save myself an hour or few of questing for the answer by just asking you good folk. So is it possible to commit to a different branch without checking that branch out first? Ideally I'd like to use the index in the same way that git commit normally does.

  • implicit parameter definition in class

    - by coubeatczech
    implicit val odkaz = head; def vypis(implicit odkaz:Prvek):String = { odkaz match{ case null => "" case e => e.cislo + " " + e.pocet + "\n" + vypis(e.dalsi) } } ... def main(args:Array[String]){ val q = new MyQueue() // insert some values println(q.vypis) } This method(vypis) is a member of an queue-class so I'll always want to implicity start the recursion from the start of the queue, when calling the method from outside. Is there a way how to write it, that the method from outside calling, there's no paramter, but in inside, there's a parameter - for recursion...? The compiler complains that the parameter is not defined when called from outside

  • php claims my defined variable is undefined

    - by tedders
    My php is a little rusty but this is boggling my mind right now. I googled this and read all the stackoverflow questions I could find that looked related, but those all seemed to have legitimate undefined variables in them. That leads me to believe that mine is the same problem, but no amount of staring at the simple bit of code I have reduced this to seems to get me anywhere. Please someone give me my dunce cap and tell me what I did wrong! <?php //test for damn undefined variable error $msgs = ""; function add_msg($msg){ $msgs .= "<div>$msg</div>"; } function print_msgs(){ print $msgs; } add_msg("test"); add_msg("test2"); print_msgs(); ?> This gives me the following, maddening output: Notice: Undefined variable: msgs in C:\wamp\www\fgwl\php-lib\fgwlshared.php on line 7 Notice: Undefined variable: msgs in C:\wamp\www\fgwl\php-lib\fgwlshared.php on line 7 Notice: Undefined variable: msgs in C:\wamp\www\fgwl\php-lib\fgwlshared.php on line 10 Yes, this is supposed to be a shared file, but at the moment I have stripped it down to just what I pasted. Any ideas?

  • Visual Studio 2010 Express for Windows Phone not installing

    - by Mohit Deshpande
    I have download and installed Visual Studio 2010 RC and I want to develop for the new Windows Phone 7. But when I run the vm_web.exe (that IS the name of the exe file, isn't it?), It still says that I haven't installed Silverlight 4.0 SDK, BUT I have installed the Silverlight SDK. In my control panel's menu, it says I have installed "Microsoft Silverlight 4 Beta SDK".

  • How could one emulate namespace in C?

    - by skydoor
    In C++ one might use namespace to keep independent groups working in the same code base from inadvertently creating functions with the same name and thus creating a conflict. My question is, before the idea of namespace comes out, how might one emulate namespace in C.
