I wanna get some data from oracle server like: 1-get all the function,package,procedure and etc for showing them or drop them & etc... 2-compile my *.sql files,get the result if they have problem & etc... becuz I was beginner in oracle first of all I for solve the second problem I try to connect to sqlPlus by RUN sqlplus and trace the output(I mean,I change the output stream of shell and trace what happend and handle the assigned message to customer. NOW THIS PART SUCCEED. just a little bit I have problem with get all result because the output is asynchronous.any way... [in this case I log in to oracle Server by send argument to the sqlplus by make a process in c#] after that I try to get all function,package or procedure name,but I have problem in speed!so I try to use oracle.DataAccess.dll to connect the database. now I m so confusing about: which way is correct way to build a program that work like Oracle Developer! I do not have any experience for like these program how work. If Your answer is I must use the second way follow this part plz: I search a little bit the Golden,PLedit (Benthic software),I have little bit problem how I must create the connection string?because I thinking about how I can find the host name or port number that oracle work on them?? am I need read the TNSNames.Ora file? IF your answer is I must use the first way follow this part plz: do u have any Idea for how I parse the output?because for example the result of a table is so confusing...[i can handle & program it but I really need someone experience,because the important things to me learn how such software work so nice and with quick response?] All of the has different style in output...

  • What the best multi-thread application debugger for C++ apps.

    - by Coredumped
    I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

  • .NET Best Way to move many files to and from various directories??

    - by Dan
    I've created a program that moves files to and from various directories. An issue I've come across is when you're trying to move a file and some other program is still using it. And you get an error. Leaving it there isn't an option, so I can only think of having to keep trying to move it over and over again. This though slows the entire program down, so I create a new thread and let it deal with the problem file and move on to the next. The bigger problem is when you have too many of these problem files and the program now has so many threads trying to move these files, that it just crashes with some kernel.dll error. Here's a sample of the code I use to move the files: Public Sub MoveIt() Try File.Move(_FileName, _CopyToFileName) Catch ex As Exception Threading.Thread.Sleep(5000) MoveIt() End Try End Sub As you can see.. I try to move the file, and if it errors, I wait and move it again.. over and over again.. I've tried using FileInfo as well, but that crashes WAY sooner than just using the File object. So has anyone found a fool proof way of moving files without it ever erroring? Note: it takes a lot of files to make it crash. It'll be fine on the weekend, but by the end of the day on monday, it's done.

  • What is the best way to properly test object equality against an array of objects?

    - by radesix
    My objective is to abort the NSXMLParser when I parse an item that already exists in cache. The basic flow of the program works like this: 1) Program starts and downloads an XML feed. Each item in the feed is represented by a custom object (FeedItem). Each FeedItem gets added to an array. 2) When the parsing is complete the contents of the array (all FeedItem objects) are archived to the disk. The next time the program is executed or the feed is refreshed by the user I begin parsing again; however, since a cache (array) now exists as each item is parsed I want to see if the object exists in the cache. If it does then I know I have downloaded all the new items and no longer need to continue parsing. What I am learning, I think, is that I can't use indexOfObject or indexOfObjectIDenticalTo: because these really seem to be checking to see that the objects are using the same memory address (thus identical). What I want to do is see if the contents of the object are equal (or at least some of the contents). I've done some research and found that I can override the IsEqual method; however, I really don't want to iterate/enumerate through the entire cache contents table for every newly parsed XML FeedItem. Is iterating through the collection and testing each one for equality the only way to do this or is there a better technique I am not aware of? Currently I am using the following code though I know it needs to change: NSUInteger index = [self.feedListCache.feedList indexOfObject:self.currentFeedItem]; if (index == NSNotFound) { }

  • What is the best way to prevent a webpage coded completely in HTML (no PHP or any server side langua

    - by racl101
    I thought by placing these two lines that it would prevent the page from being cached but this is not the case between the head tags: <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="cache-control" content="no-cache" /> As already mentioned this is on server that doesn't support PHP (or any server side language, well, that's not true, it has cgi-bin folder that supports perl scripts but I don't know perl and have no time to engage in it.) What else could I do to prevent the page from caching? It caches on Firefox and IE (and not so much in Chrome or Safari.)

  • from JS to iphone dev - what's the best language to start with?

    - by Enkai
    I am a total beginner and would like to eventually learn to develop for the iphone. I have just done a beginner's CS course where the language we learned was JavaScript. We studied basic concepts like: variables, arrays, loops (for,while,if,if..else..), properties and functions. I'm wondering if I am starting in the right/wrong place by following this book: Learn C on the Mac by Dave Mark? I have read a few chapters and am finding it a bit hard to get my head around the way that C works, for example the way that Strings are printed seems overly complicated as compared to JS. Do you think that JS was the wrong language to start off with and would I be better to go from JS straight to Objective-C rather than to C? I have tried to read up on previous threads on the merits/demerits of learning C first but haven't found any that relate JS to learning C/Obj C/ Cocoa. Any advice appreciated as I am very new to this. Thanks

  • What is the best way to make a game timer in Actionscript 3?

    - by Nuthman
    I have built an online game system that depends on a timer that records how long it took a player to complete a challenge. It needs to be accurate to the millisecond. Their time is stored in a SQL database. The problem is that when I use the Timer class, some players are ending up getting scores in the database of less than a second. (which is impossible, as most challenges would take at least 11 seconds to complete even in a perfect situation.) What I have found is that if a player has too many browser windows open, and/or a slow computer, the flash game slows down actually affecting the timer speed itself. The timer is 'spinning' on screen so you can physically see the numbers slowing down. It is frustrating that I cannot just open a second thread or do something to allow flash to keep accurate time regardless of whatever else is going on in the program. Any ideas?

  • Where is the best place to start learning Java Socket Programming?

    - by MarcoBoomTing
    I wish to create a Java Socket server which can be connected to using Javascript and/or Flash. I have experience in Connecting to sockets in flash, and using a comet like system in Ajax. I wish to make a live communication system, which will intale multiple connections to the server from various clients, needing almost instant communication between peers. I coded a system like this in PHP but I want to convert it to Java, simply because I don't want the PHP engine to be tied up on this Sever, as it serves all the web stuff normally on the site, and i've heard is more powerful for this sort of thing. Just looking for advice on where I can start learning how to write this sort of system using Java? I have previous coding experience in PHP, Javascript, Adobe Air and AS3 if That helps?

  • What is the best businessmodel when using NHibernate to access the database?

    - by Sem Dendoncker
    Hi, I'm starting to use NHiberante as a dataaccess tier. I'm used to work with the repository model as a business model. This means, my domain model (not really a tier), my asp.net application tier, my repository tier which finally uses my dataaccess tier. But with what I've learned by now (on NHibernate) I know that many logic is done within an ISession so I was wondering if NHibernate could be used within the repository tier. Or perhaps there are even better ways to use NHibernate. Does anyone know where I could find a propriate example of how to use NHibernate in an webapplication? Cheers, M.

  • Best practices for packaging resources (jpg's, sound, video) in an iPhone app?

    - by Mel
    I'm a newb iPhone developer writing an app that has several large JPGs and sound files. Everything works ok if I drag these non-code resources into my project. But I am wondering if this is the right way to package my app. In Windows development, I would create a "resource DLL" that keeps the .exe size small. What is the equivalent for iPhone? I think I should be creating a "bundle" - can someone please give me some pointers to using these and how to link them into my main project? Thanks!

  • What's the best way to use hamcrest-AS3 to test for membership in an IList?

    - by Chris R
    I'm using Flex 3.3, with hamcrest-as3 used to test for item membership in a list as part of my unit tests: var myList: IList = new ArrayCollection(['a', 'b', 'c']).list; assertThat(myList, hasItems('a', 'b', 'c')); The problem is that apparently the IList class doesn't support for each iteration; for example, with the above list, this will not trace anything: for each (var i: * in myList) { trace (i); } However, tracing either an Array or an ArrayCollection containing the same data will work just fine. What I want to do is (without having to tear apart my existing IList-based interface) be able to treat an IList like an Array or an ArrayCollection for the purposes of testing, because that's what hamcrest does: override public function matches(collection:Object):Boolean { for each (var item:Object in collection) { if (_elementMatcher.matches(item)) { return true; } } return false; } Is this simply doomed to failure? As a side note, why would the IList interface not be amenable to iteration this way? That just seems wrong.

  • What's the best editor/program for g++ in Linux?

    - by Phenom
    So far I've been using vi, but I'm wondering if there's something better to use in Linux. In Windows there's Visual C++, and I guess practically all C++ programmers in Windows use this these days. It has a lot of things in it to help the programmer. What about for Linux?

  • Best environment to port C/C++ code from Linux to Windows.

    - by Simone Margaritelli
    I'd like to make a big project of mine buildable on Windows platforms. The project itself it's written in C/C++ following POSIX standards, with some library dependencies such as libxml2, libcurl and so on. I'm more a Linux developer rather than a Windows developer, so i have no idea of which compiler suite i should use to port the code. Which one offers more compatibility with gcc 4.4.3 i'm using right now? My project needs flex and bison, is there any "ready to use" environment to port such projects to windows platforms? Thanks.

  • best way to store php data on a page for use with javascript/jquery?

    - by Haroldo
    Ok, so im trying to work out the fastest way of storing data on my page without slowing the page load: I need to store information in the page to be later used by jquery. My page is an events page and i want to attach data to each event anchor. there are 100+ events to attach data to. The events anchors are created with a php loop, so i could create the data elements within this loop using either use un-semantic tags ie *rel="some_data"* create a jquery.data() for each iteration of the loop or i could run the loop again, separately, this time inside script tags with jquery.data(); would really appreciate any thoughts on this!
