  • how to use execute() in groovy to run any command

    - by drake
    I usually build my project using these two commands from command line (dos) G:\> cd c: C:\> cd c:\my\directory\where\ant\exists C:\my\directory\where\ant\exists> ant -Mysystem ... ..... build successful What If I want to do the above from groovy instead? groovy has execute() method but following does not work for me: def cd_command = "cd c:" def proc = cd_command.execute() proc.waitFor() it gives error: Caught: java.io.IOException: Cannot run program "cd": CreateProcess error=2, The system cannot find the file specified at ant_groovy.run(ant_groovy.groovy:2)

  • warning: (Internal error: pc 0x804a6b0 in read in psymtab, but not in symtab.) g++

    - by Sriram
    Hi, I am trying to debug a program using ddd. When I try to enter any function, or within main() itself, I get the following warning: warning: (Internal error: pc 0x804a6b0 in read in psymtab, but not in symtab.) This warning flashes whenever I try to move to another instruction using 'n' or enter or leave a function. I have tried to look this up in other forums, but with no conclusive answer. The code I am trying to debug runs into several files and I am not sure if I can post the entire code here. I am using g++ version: g++ (GCC) 4.4.1 20090725 (Red Hat 4.4.1-2) Any help on this is most welcome. Thanks, Sriram.

  • Question regarding C++ Templates

    - by Isuru
    I used a simple class for a test program about templates, this is what I did: template <typename T> class test { public: test<T>::test(); T out(); }; template <typename T> test<T>::test() { } T test<T>::out() { } int main() { //test<int> t; } But when I try to compile it says 'T' : undeclared identifier and use of class template requires template argument list , pointing to the same line, where I have implemented the method out() . Can anyone please explain what the problem is?? I'm using visual studio 2008.

  • Reading and writing to SysV shared memory without synchronization (use of semaphores, C/C++, Linux)

    - by user363778
    Hi, I use SysV shared memory to let two processes communicate with each other. I do not want the code to become to complex so I wondered if I really had to use semaphores to synchronize the access to the shared memory. In my C/C++ program the parent process reads from the shared memory and the child process writes to the shared memory. I wrote two test applications to see if I could produce some kind of error like a segmentation fault, but I couldn't (Ubuntu 10.04 64bit). Even two processes writing non stop in a while loop to the same shared memory did not produce any error. I hope someone has experience concerning this matter and can tell me if I really must use semaphores to synchronize the access or if I am OK without synchronization. Thanks

  • Form Inheritance in Visual Studios designer implementations

    - by CooPzZ
    I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class

  • Using netlink to obtain arp entries only returns stale entries

    - by Ben
    I'm currently trying to retrieve reachable neighbors from the arp table in a user space program written in c. I've looked through the source code to the "ip neigh" command (ipneigh.c) and it appears that I should use the flag NUD_REACHABLE. struct { struct nlmsghdr n; struct ndmsg r; } req; memset(&req, 0, sizeof(req)); req.n.nlmsg_len = NLMSG_LENGTH(sizeof(struct ndmsg)); req.n.nlmsg_flags = NLM_F_REQUEST | NLM_F_ROOT; req.n.nlmsg_type = RTM_GETNEIGH; req.r.ndm_state = NUD_REACHABLE; However, when I look at the data returned from the kernel, I only have stale entries. In fact, no matter what I put for req.r.ndm_state it seems to return only entries marked as stale by ip neigh. The remainder of my code is modeled after this example: http://linux-hacks.blogspot.com/2009/01/sample-code-to-learn-netlink.html

  • Puttting together binding navigators in a project

    - by vp789
    I am working on a group project in vb.net, in which all my team members are working on individual tables of a database. All of us are using binding navigator,where the GUI is created by drag and drop from the table. Is it possible to attach all these pieces together with imports or references? Will the changes made to the database while working on the program like table adapter can create problem? Do I need to make all those changes in database before importing ? Can you please give suggestions to put the project together.

  • Can PHP Perform Magic Instantiation?

    - by Aiden Bell
    Despite PHP being a pretty poor language and ad-hoc set of libraries ... of which the mix of functions and objects, random argument orders and generally ill-thought out semantics mean constant WTF moments.... ... I will admit, it is quite fun to program in and is fairly ubiquitous. (waiting for Server-side JavaScript to flesh out though) question: Given a class class RandomName extends CommonAppBase {} is there any way to automatically create an instance of any class extending CommonAppBase without explicitly using new? As a rule there will only be one class definition per PHP file. And appending new RandomName() to the end of all files is something I would like to eliminate. The extending class has no constructor; only CommonAppBase's constructor is called. Strange question, but would be nice if anyone knows a solution. Thanks in advance, Aiden (btw, my PHP version is 5.3.2) Please state version restrictions with any answer.

  • Teaching a mainframe COBOL programmer Java?

    - by Jared
    I’m trying to help someone learn Java who’s only programming experience is COBOL on the mainframe. I was wondering if anyone knew any good resources for object oriented concepts. I learned how to program with C++ so just understand the theory behind basic OOP. I’m more concerned about a way to get the basic concepts across, such as encapsulation and inheritance rather then Java syntax. I think it’d be better to teach the concepts of OOP then a language rather then trying to cram both a new language and paradigm in at the same time. Does anyone have any resources or ideas that could help this person learn OOP followed by Java?

  • SSIS Script Component, Allow Null values

    - by user2471943
    I have a SSIS package that I am programming and my script component won't allow null column inputs. I have checked the box to keep nulls in the flat file source component. My program is running well until my script component where I get the error "The column has a null value" (super vague, I know). The column currently throwing the error is an "int" valued column and is used for aggregations in my script. I could make the null values 0s or to say "NULL" but I'd prefer to just leave them blank. Any advice on how to handle this problem would be greatly appreciated! Thanks in advance! I am using SQL Server BIDS 2008.

  • Images saved with D3DXSaveSurfaceToFile will open in Paint, not Photoshop

    - by bsruth
    I'm using D3DXSaveSurfaceToFile to save windowed Direct3D 9 surfaces to PNG, BMP and JPG files. There are no errors returned from the D3DXSaveSurfaceToFile call and all files open fine in Windows Photo Viewer and Paint. But they will not open in a higher end image editing program such as Paint Shop Pro or Photoshop. The error messages from these programs basically say that the file is corrupted. If I open the files in Paint and then save them in the same file format with a different file name, then they'll open fine in the other programs. This leads me to believe that D3DXSaveSurfaceToFile is writing out non-standard versions of these file formats. Is there some way I can get this function to write out files that can be opened in programs like Photoshop without the intermediate step of resaving the files in Paint? Or is there another function I should be using that does a better job of saving a Direct3D surfaces to an image?

  • Best Application for storing code snippets

    - by Konrad
    Hi all, Just wondering if you can point me in the direction of a simple, fast program which stores code snippets. I have been using a local wiki up to now, but I find it a little annoying at times. Ideally I would like this application to be portable - i.e. it could run off of a USB stick on multiple machines with no installation. What do you guys use? EDIT: I would prefer a solution that was decoupled from the IDE and stored locally, not in the cloud. EDIT 2: Thanks for all the replies thus far, but I am still awaiting a non cloud / web based portable solution. Anyone else care to weigh in? :)

  • IE7 Times Out Debugging ASP.Net Page

    - by Eric J.
    My issue is similar to ASP.NET Debugging Timing out with IIS except that I'm using the built-in ASP.Net Development Server with VS 2010. If I pause for more than about 10 seconds in the debugger, IE7 "disconnects" from the web server with the error message Internet Explorer cannot display the webpage However, unlike in the similar question, the debugger is still running. If I refresh the browser it will post that refresh to the server and I can debug the page from the top again. Is it possible to configure things so that IE7 waits (much) longer before giving up? If it makes a difference, I'm launching IE using the "Start external program" option and passing a localhost URL as the command line argument (since Chrome is my default browser). I also specify a specific port.

  • Making Eclipse behave like Visual Studio

    - by FlySwat
    I'm doing some Android dev, and I much prefer Visual Studio, but I'll have to use Eclipse for this. Has anyone made a tool that switches Eclipse to look and behave more like visual studio? I mainly can't stand its clippyesqe suggestions on how I should program (Yes, I know I have not yet used that private field! Thanks Eclipse!), or its incredibly lousy intellisense. For example, in eclipse, if I don't type "this" first, its intellisense won't realize I want to look for locally scoped members. Also, the TAB to complete VS convention is drilled into my head, and Eclipse is ENTER to complete, I could switch everything by hand but that would take hours, and I was hoping someone had some sort of theme or something that has already done it :)

  • Why are nanosleep() and usleep() too slow?

    - by user351990
    I have a program that generates packets to send to a receiver. I need an efficient method of introducing a small delay between the sending of each packet so as not to overrun the receiver. I've tried usleep() and nanosleep() but they seem to be too slow. I've implemented a busy wait loop and had more success, but it's not the most efficient method, I know. I'm interested in anyone's experiences in trying to do what I'm doing. Do others find usleep() and nanosleep() to function well for this type of application? Thanks, Danny Llewallyn

  • Suggestion for creating custom sound recognition software to toggle audio

    - by Parrot owner
    I need to develop a program that toggles a particular audio track on or off when it recognizes a parrot scream or screech. The software would need to recognize a particular range of sounds and allow some variations in the range (as a parrot likely won't replicate its sreeches EXACTLY each time). Example: Bird screeches, no audio. Bird stops screeching for five seconds, audio track praising the bird plays. Regular chattering needs to be ignored completely, as it is not to be discouraged. I've heard of java libraries that have speech recognition with dictionaries built in, but the software would need to be taught the particular sounds that my particular parrot makes - not words or any random bird sound. In addition as I mentioned above, it would need to allow for slight variation in the sound, as the screech will likely never be 100% identical to the recorded version. What would be the best way to go about this/what language should I look into?

  • How to send date from one view to another in xcode?

    - by Egor Sosin
    I want to make the program where you have to enter some data, and then it will manipulate that data and show it on the other view when you click done. I search through multiple tutorials, but still cant understand how you do that. I have a textfield - lesson1 and want to pass it to the label in the second view. The views are called EditClasses and DayView. Thanks a lot. Also I need to change the data every 24 hours, what is the best way to do it?

  • Understanding top output in Linux

    - by Rayne
    Hi, I'm trying to determine the CPU usage of a program by looking at the output from Top in Linux. I understand that %us means userspace and %sy means system/kernel etc. But say I see 100%us. Does this mean that the CPU is really only doing useful work? What if a CPU is tied up waiting for resources that are not avaliable, or cache misses, would it also show up in the %us column, or any other column? Thank you.

  • How does Mach-O loader recognize a bunch of NSString objects?

    - by overboming
    I have known that If you define a bunch of @"" NSString objects in the source code in Mac OS. These NSStrings will be stored in a segment in the Mach-O library. Section sectname __ustring segname __TEXT addr 0x000b3b54 size 0x000001b7 offset 731988 align 2^1 (2) reloff 0 nreloc 0 flags 0x00000000 reserved1 0 reserved2 0 If I hex dump the binary, they are aligned closely one by one with a 0x0000as separator. What I want to know is how does the loader in Mac OS X load these NSStrings when the program runs? Are they loaded simpily by recognize the 0x0000 separator or these is a string offset table elsewhere in the binary pointing to separate NSString objects? Thanks. (What I really want to do is the increase the length of one of the NSString, so I have to know how the loader recognize these separate objects)

  • How can I synchronize database access between a write-thread and a read-thread?

    - by Runcible
    My program has two threads: Main execution thread that handles user input and queues up database writes A utility thread that wakes up every second and flushes the writes to the database Inside the main thread, I occasionally need to make reads on the database. When this happens, performance is not important, but correctness is. (In a perfect world, I would be reading from a cache, not making a round-trip to the database - but let's put that aside for the sake of discussion.) How do I make sure that the main thread sees a correct / quiescent database? A standard mutex won't work, since I run the risk of having the main thread grab the mutex before the data gets flushed to the database. This would be a big race condition. What I really want is some sort of mutex that lets the main thread of execution proceed only AFTER the mutex has been grabbed and released once. Does such a thing exist? What's the best way to solve this problem?

  • Which data structure(s) to back a Final Fantasy ATB-style queue? (a delay queue)

    - by ZoFreX
    Situation: There are several entities in a simulated environment, which has an artificial notion of time called "ticks", which has no link to real time. Each entity takes it in turns to move, but some are faster than others. This is expressed by a delay, in ticks. So entity A might have a delay of 10, and B 25. In this case the turn order would go: A A B A A I'm wondering what data structure to use. At first I automatically thought "priority queue" but the delays are relative to "current time" which complicates matters. Also, there will be entities with larger delays and it's not unforseeable that the program will run through millions of ticks. It seems silly for an internal counter to be building higher and higher when the delays themselves stay relatively small and don't increase. So how would you solve this?

  • uneven illuminated images

    - by coul
    How to get rid of uneven illumination from images, that contain text data, usually printed but may be handwritten? It can have some spots of lights because the light reflected while making picture. I've seen the Halcon program's segment_characters function that is doing this work perfectly, but it is not open source. I wish to convert an image to the image that has a constant illumination at background and more dark colored regions of text. So that binarization will be easy and without noise. The text is assumed to be dark colored than it's background. Any ideas?

  • administrator permission are recommended for running visual studio sp1 on windows 7 rc

    - by vinayakg
    I get this annoying message everytime I try to run visual studio 2005(even using "Run as Administrator" gives same message). I have VS 2005 Professional with all the latest service packs installed including vs2005 SP1 and vs 2005 update for Vista. I am part of the administrators group on my machine. Still I have this problem. Some read on the web suggests that Running program in Compatibility mode solves the problem. Others also recommend turning off the message forever. Well my question is how do I turn off this warning which seems to bother me even if I am part of administrators group. Does Visual Studio does not run in administrator mode even when I am an administrator or even I use "Run as adminsitrator". Also it would be greate if someone out there can highlight what features of Visual Studio wont be available if Visual Studio is launched as a normal user (User is not an administrator/part of the administrator group) on Windows 7.
