  • Using static variable in function vs passing variable from caller

    - by Patrick
    I have a function which spawns various types of threads, one of the thread types needs to be spawned every x seconds. I currently have it like this: bool isTime( Time t ) { return t >= now(); } void spawner() { while( 1 ) { Time t = now(); if( isTime( t ) )//is time is called in more than one place in the real function { launchthread() t = now() + offset; } } } but I'm thinking of changing it to: bool isTime() { static Time t = now(); if( t >= now() ) { t = now() + offset; return true; } return false; } void spawner() { if( isTime() ) launchthread(); } I think the second way is neater but I generally avoid statics in much the same way I avoid global data; anyone have any thoughts on the different styles?

  • Is key 'chord' functionality provided by Win32/.net?

    - by John
    Several MS apps support the concept of chords, like "CTRL+X,Y" which means "holding down CTRL, press X, then Y". Is this a bespoke thing they (and other companies) implement, or is it built into any APIs? It would be nice to be able to set up event handlers or accelerators based on chords rather than write code to do it.

  • Should I invest time in learning about OR\M or LINQ?

    - by Peter Smith
    I'm a .NET web developer primarily who occasionally writes console applications to mine data, cleanup tasks, etc. Most of what I do winds up involving a database which I currently design via sql server management studio, using stored procedures, and query analyzer. I also create a lot of web services which are consumed via AJAX applications. Do these technologies really help you in speeding up development times? Do you still have to build the database or object code first?

  • Apply a Quartz filter while saving PDF under Mac OS X 10.6.3

    - by olpa
    Using Mac OS X API, I'm trying to save a PDF file with a Quartz filter applied, just like it is possible from the "Save As" dialog in the Preview application. So far I've written the following code (using Python and pyObjC, but it isn't important for me): -- filter-pdf.py: begin from Foundation import * from Quartz import * import objc page_rect = CGRectMake (0, 0, 612, 792) fdict = NSDictionary.dictionaryWithContentsOfFile_("/System/Library/Filters/Blue \ Tone.qfilter") in_pdf = CGPDFDocumentCreateWithProvider(CGDataProviderCreateWithFilename ("test .pdf")) url = CFURLCreateWithFileSystemPath(None, "test_out.pdf", kCFURLPOSIXPathStyle, False) c = CGPDFContextCreateWithURL(url, page_rect, fdict) np = CGPDFDocumentGetNumberOfPages(in_pdf) for ip in range (1, np+1): page = CGPDFDocumentGetPage(in_pdf, ip) r = CGPDFPageGetBoxRect(page, kCGPDFMediaBox) CGContextBeginPage(c, r) CGContextDrawPDFPage(c, page) CGContextEndPage(c) -- filter-pdf.py: end Unfortunalte, the filter "Blue Tone" isn't applied, the output PDF looks exactly as the input PDF. Question: what I missed? How to apply a filter? Well, the documentation doesn't promise that such way of creating and using "fdict" should cause that the filter is applied. But I just rewritten (as far as I can) sample code /Developer/Examples/Quartz/Python/filter-pdf.py, which was distributed with older versions of Mac (meanwhile, this code doesn't work too): ----- filter-pdf-old.py: begin from CoreGraphics import * import sys, os, math, getopt, string def usage (): print ''' usage: python filter-pdf.py FILTER INPUT-PDF OUTPUT-PDF Apply a ColorSync Filter to a PDF document. ''' def main (): page_rect = CGRectMake (0, 0, 612, 792) try: opts,args = getopt.getopt (sys.argv[1:], '', []) except getopt.GetoptError: usage () sys.exit (1) if len (args) != 3: usage () sys.exit (1) filter = CGContextFilterCreateDictionary (args[0]) if not filter: print 'Unable to create context filter' sys.exit (1) pdf = CGPDFDocumentCreateWithProvider (CGDataProviderCreateWithFilename (args[1])) if not pdf: print 'Unable to open input file' sys.exit (1) c = CGPDFContextCreateWithFilename (args[2], page_rect, filter) if not c: print 'Unable to create output context' sys.exit (1) for p in range (1, pdf.getNumberOfPages () + 1): #r = pdf.getMediaBox (p) r = pdf.getPage(p).getBoxRect(p) c.beginPage (r) c.drawPDFDocument (r, pdf, p) c.endPage () c.finish () if __name__ == '__main__': main () ----- filter-pdf-old.py: end

  • How to simulate a dial-up connection for testing purposes?

    - by mawg
    I have to code a server app where clients open a TCP/IP socket, send some data and close the connection. The data packets are small < 100 bytes, however there is talk of having them batch their transactions and send multiple packets. How can I best simulate a dial-up ut connection (using Delphy & Indy components, just FYI)? Is it as simple as open connection wait a while (what is the definition of "a while"?) close connection

  • How do you pronounce "Enum"?

    - by Davy8
    In the spirit of this question how do you pronounce Enum? Tagging as subjective and community wiki obviously. I've heard E-Nuhm and E-Nnoom any others? Edit: Looks like we have a winner. Thought it'd be a closer race since most of the people at my work use the 2nd one.

  • Visual Studio 2010 Language Support

    - by inspectorG4dget
    Hello SO, I want to be able to develop code using Visual Studio 2010. I just got VS2010 and I'm not able to get the languages I want on it. The main reason that I'm asking this is that I'm trying to migrate to ONE IDE that does it all for me. Thus far eclipse has been doing a good job, but I've been informed that VS2010 is better and I'm trying to get into the groove of that standard So my question is two-fold. I am not able to find a complete list of languages supported by VS2010. What are these languages? How can I get VS2010 support for: a. Python/IronPython b. C/C++/C#/XNA c. Java My Googling has given me no promising/definitive results. I'd really appreciate any help.

  • XCode and developer tools

    - by Infinity
    Hello guys! I want to use the FileMerge utility on my mac, but it isn't installed. I searched in the google and there is written that it will be installed with the developer tools. So the big question is where can I find the developer tools, because I downloaded the iPhone SDK 3.2 beta 5, and installed it, but I can't found the download location of developer tools. Maybe can you help me?

  • How can I demonstrate the benefits of abstractions to an old-time C programmer?

    - by Zaban Khuli
    Hi, there's this senior developer in my company that programs in C. I happen to be from functional background (ML, to be specific). This senior C programmer refuses to use abstractions because "abstraction is for lame programmers and _real_ programmers do not need it." I can not seem to convince him otherwise Is it a problem with only this programmer or do all C (and other lower level language) programmers have this opinion that abstraction is for lame programmers?

  • Could I be writing this code better?

    - by Ben Dauphinee
    Is there any website out there somewhere where a programmer such as myself might be able to post pieces of code to be looked at by more experienced people? I am thinking of something that programmers could use to have advice given on how to improve their ability. I really like the atmosphere here, but am not sure that posting code for review here is appropriate.

  • Telling someone to "let the world judge their development practices" without being condicending?

    - by leeand00
    There's a person in management on my team, that: Doesn't ask questions on Stack Overflow. Doesn't read development blogs. Doesn't use development best practices. This person is about to make some major decisions about the technology stack that will be used throughout the company. (I asked him what the technology stack was they were planning to use was, and it included many things that are not even development tools). How can I tell them to "Let the world's experience" judge their development practices, before they set them in stone; without being condescending or upsetting them?

  • How can i learn file name and create a folder?

    - by Phsika
    i try to make TCP/Ip Application to listen any other roemote computer to recieve any file. So i try to get files. i can do that. on the other hand every sample on google about giving SaveDialogBox to recived path folder.Forexample my old server.cs is that: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; using System.Net; using System.Net.Sockets; using System.Threading; namespace Server3 { public partial class Form1 : Form { Thread kanal; public Form1() { InitializeComponent(); try { kanal = new Thread(new ThreadStart(Dinle)); kanal.Start(); kanal.Priority = ThreadPriority.Normal; this.Text = "Kanal Çalisti"; } catch (Exception ex) { this.Text = "kanal çalismadi"; MessageBox.Show("hata:" + ex.ToString()); kanal.Abort(); throw; } } void Dinle() { TcpListener server = null; try { Int32 port = 51124; IPAddress localAddr = IPAddress.Parse("127.0.0.1"); server = new TcpListener(localAddr, port); server.Start(); Byte[] bytes = new Byte[1024 * 250000]; // string ReceivedPath = "C:/recieved"; while (true) { MessageBox.Show("Waiting for a connection... "); TcpClient client = server.AcceptTcpClient(); MessageBox.Show("Connected!"); NetworkStream stream = client.GetStream(); if (stream.CanRead) { saveFileDialog1.ShowDialog(); string pathfolder = saveFileDialog1.FileName; StreamWriter yaz = new StreamWriter(pathfolder); string satir; StreamReader oku = new StreamReader(stream); while ((satir = oku.ReadLine()) != null) { satir = satir + (char)13 + (char)10; yaz.WriteLine(satir); } oku.Close(); yaz.Close(); client.Close(); } } } catch (SocketException e) { Console.WriteLine("SocketException: {0}", e); } finally { // Stop listening for new clients. server.Stop(); } Console.WriteLine("\nHit enter to continue..."); Console.Read(); } private void Form1_Load(object sender, EventArgs e) { Dinle(); } } } i want to give automatically folder without SAVEDIALOGBOX. Also i want to learn my file name om my stream.Like that: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.IO; using System.Net; using System.Net.Sockets; using System.Threading; namespace Server3 { public partial class Form1 : Form { Thread kanal; public Form1() { InitializeComponent(); try { kanal = new Thread(new ThreadStart(Dinle)); kanal.Start(); kanal.Priority = ThreadPriority.Normal; this.Text = "Kanal Çalisti"; } catch (Exception ex) { this.Text = "kanal çalismadi"; MessageBox.Show("hata:" + ex.ToString()); kanal.Abort(); throw; } } void Dinle() { TcpListener server = null; try { Int32 port = 51124; IPAddress localAddr = IPAddress.Parse("127.0.0.1"); server = new TcpListener(localAddr, port); server.Start(); Byte[] bytes = new Byte[1024 * 250000]; string ReceivedPath = "C:/recieved"; while (true) { MessageBox.Show("Waiting for a connection... "); TcpClient client = server.AcceptTcpClient(); MessageBox.Show("Connected!"); NetworkStream stream = client.GetStream(); if (stream.CanRead) { saveFileDialog1.ShowDialog(); string pathfolder = " i have to give property creating path and want to learn file name"; StreamWriter yaz = new StreamWriter(pathfolder); string satir; StreamReader oku = new StreamReader(stream); while ((satir = oku.ReadLine()) != null) { satir = satir + (char)13 + (char)10; yaz.WriteLine(satir); } oku.Close(); yaz.Close(); client.Close(); } } } catch (SocketException e) { Console.WriteLine("SocketException: {0}", e); } finally { // Stop listening for new clients. server.Stop(); } Console.WriteLine("\nHit enter to continue..."); Console.Read(); } private void Form1_Load(object sender, EventArgs e) { Dinle(); } } } Also i need : FileStream fs; FileInfo fi = new FileInfo(@"c:/recieved"); if (fi.Exists) fs = new FileStream(fi.FullName, FileMode.Append); else fs = new FileStream(fi.FullName, FileMode.Create); StreamWriter yazici = new StreamWriter(fs); How can i do that. Creating C:/recieved if it does not exist. And how can i learn File name on my network stream sending File Name.

  • Enumerating computers in NT4 domain using WNetEnumResourceW (C++) or DirectoryEntry (C#)

    - by Kevin Davis
    I'm trying to enumerate computers in NT4 domains (not Active Directory) and support Unicode NetBIOS names. According to MSDN, WNetEnumResourceW is the Unicode counterpart of WNetEnumResource which to me would imply that using this would do the trick. However, I have not been able to get Unicode NetBIOS names properly using WNetEnumResourceW. I've also tried the C# rough equivalent DirectoryEntry using the WinNT: provider with no luck on Unicode names either. If I use DirectoryEntry on Active Directory (using the LDAP: provider) I do get Unicode names back. I noticed that during some debugging my code using DirectoryEntry and the WinNT: provider, the exceptions I saw were of type System.Runtime.InteropServices.COMException which tends to make me believe that this is just calling WNetEnumResourceW via COM. This web page implies that for some Net APIs the MS documentation is incomplete and possibly inaccurate which further confuses things. Additionally I've found that using the C# method which certainly results in cleaner, more understandable code also yields incomplete results in enumerating computers in domains\workgroups. Does anyone have any insight on this? Is it possible that computer acting as the WINS server is mangling the name? How would I determine this? Thanks

  • Winsock failed to connect to local ip address

    - by JKS
    I have used the following code in a form that acts like a server, WskServer(0).Close LocalIP = WskServer(0).LocalIP WskServer(0).LocalPort = DEFAULT_TCP_PORT WskServer(0).Protocol = sckTCPProtocol txtStatus.Text = "Starting server" Call WskServer(0).Bind(DEFAULT_TCP_PORT, LocalIP) WskServer(0).Listen when i execute above code,i received the following error "Address is not available from the local machine" . If i changed the line Call WskServer(0).Bind(DEFAULT_TCP_PORT, LocalIP) to Call WskServer(0).Bind(DEFAULT_TCP_PORT, "127.0.0.1") this is working What's wrong with the code?, can anybody give the fix Update I just removed the line Call WskServer(0).Bind(DEFAULT_TCP_PORT, LocalIP) now server working properly. this way is correct or not
