  • Command prompt print dialog command

    - by wrongusername
    Is there any way a C++ commandline program on Windows can produce a graphical GUI print dialog for printing to a printer, just like usual GUI programs? I've combed through this webpage and it seems there are only commands that print files in the background to a pre-determined printer.

  • Windows application data directory

    - by Stefan
    With the environment variable %allusersprofile% I can get the directory where common settings are stored. But most programs store their settings in the sub-folder "anwendungsdaten" (German, application data). Is there a way to get the direct path to this folder? The problem is that its name is language dependent. Thanks.

  • Which mobile operating system should I code for?

    - by samgoody
    It seems as though mobile computing has fully arrived. I would like to rewrite two of our programs for mobile devices, but am a bit lost as to which platform to target. Complicating this decision: I would need to learn the relevant languages and IDEs - my coding to date has been almost all web based (PHP, JS, Actionscript, etc. Some ASPX). Most users seem to be religious about their mobile decision, so oral conversations leave me more confused then enlightened. I do not yet own a smartphone - will have to buy one once I know which platform to be aiming for. Both of my programs are more for business users, (one is only useful for C.P.A.s). I am a single developer, and cannot develop for more than one platform at a time. Getting it right is important. Based on what I've found on the web, I would've expected RIM to be a shoo-in, and the general order to be as follows: RIM Blackberry - More of them than any other brand. Despite naysayers, they've had double the sales (or perhaps 5X the sales) of any other smartphone, and have continued to grow. And, they have business users. Android - According to Schmidt, they have outsold everyone else except RIM (though I can't find where I read that now), and they are just getting started. According to Comscore, they are already at 8% of the market and expected to hit Shcmidt's claims within six months. Nokia - The largest worldwide. If they would just make up between Maemo or Symbian, I would be far less confused. iPhone - Much more competition by other apps, fewer sales to be had, and a overlord that can delay or cancel my app at any time. Is Cocoa hard to learn? Windows Mobile - Word is that version 7 will not be backwards compatible and losing market share. Palm WebOS - Perhaps this should go first, as it is the only one that offers tools to make my life easy as a web application developer. No competition in marketplace. But not very many users either. However, a search on StackOverflow shows a hugely disproportionate number of iPhone questions versus Blackberry. Likewise, there are clearly more apps on iPhone, so it must be getting developer love. What is the one platform I should develop for? Please back up your answer with the logic.

  • Command line semaphore utility

    - by compie
    I want to write a command line utility that can be used to synchronize the execution off programs in different consoles. Console A: $ first_program && semaphore -signal Console B: $ semaphore -wait && second_program The first program takes a long take to complete. The second program can only start when the first program has finished. Which synchronization object do I need to implement this (in Python)?

  • What's the best way to trim std::string

    - by Milan Babuškov
    I'm currently using the following code to right-trim all the std::strings in my programs: std::string s; s.erase(s.find_last_not_of(" \n\r\t")+1); It works fine, but I wonder if there are some end-cases where it might fail? Of course, answers with elegant alternatives and also left-trim solution are welcome.

  • Coexisting installation of visual studio 2010 &2008

    - by yCalleecharan
    Hi, I currently have MVS2008 and I want to try the 2010 version hoping that it would compile C programs faster. I would like to know if I can have a 2008 installation coexisting with a 2010 installation on the same Windows partition, without conflicts in the Windows environment variables in Win XP. Thanks a lot...

  • How to stop emacs from replacing underbar with <- in ess-mode

    - by SetJmp
    ess-mode is "Emacs speaks statistics." This mode is useful for editing programs for R or Splus (two separate statistics packages). In my buffer, when ever I type '_' the character is replaced with "<-" which is very frustrating. Is there a emacs lisp statement to turn off this behavior? Thanks, SetJmp emacs: 22.1.1 ess-mode release (unknown)

  • stringstream problem - vector iterator not dereferencable

    - by andreas
    Hello I've got a problem with the following code snippet. It is related to the stringstream "stringstream css(cv.back())" bit. If it is commented out the program will run ok. It is really weird, as I keep getting it in some of my programs, but if I just create a console project the code will run fine. In some of my Win32 programs it will and in some it won't (then it will return "vector iterator not dereferencable" but it will compile just fine). Any ideas at all would be really appreciated. Thanks! vector<double> cRes(2); vector<double> pRes(2); int readTimeVects2(vector<double> &cRes, vector<double> &pRes){ string segments; vector<string> cv, pv, chv, phv; ifstream cin("cm.txt"); ifstream pin("pw.txt"); ifstream chin("hm.txt"); ifstream phin("hw.txt"); while (getline(cin,segments,'\t')) { cv.push_back(segments); } while (getline(pin,segments,'\t')) { pv.push_back(segments); } while (getline(chin,segments,'\t')) { chv.push_back(segments); } while (getline(phin,segments,'\t')) { phv.push_back(segments); } cin.close(); pin.close(); chin.close(); phin.close(); stringstream phss(phv.front()); phss >> pRes[0]; phss.clear(); stringstream chss(chv.front()); chss >> cRes[0]; chss.clear(); stringstream pss(pv.back()); pss >> pRes[1]; pss.clear(); stringstream css(cv.back()); css >> cRes[1]; css.clear(); return 0; }

  • Glassfish V3 won't start

    - by Zakaria
    Hi everybody, I installed NetBeans 6.8 and tried to run the GlasshFish V3 server. I'm working under Windows Vista 32 Bits. First, it won't run.

  • Flex Spark DropDownList selectedItem didn't update after dataProvider changed

    - by Candy Chiu
    I have two dataProvider's for one DropDownList. The following code can be compiled and run. <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" creationComplete="flipLast()" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ import mx.collections.ArrayCollection; public function flipLast():void { if( last ) { list.dataProvider = dp1; list.selectedItem = "Flex"; } else { list.dataProvider = dp2; list.selectedItem = "Catalyst"; } last = !last; } public var last:Boolean = true; public var dp1:ArrayCollection = new ArrayCollection( [ "Flex", "Air" ] ); public var dp2:ArrayCollection = new ArrayCollection( [ "Catalyst", "FlashBuilder" ] ); ]]> </fx:Script> <s:VGroup> <s:DropDownList id="list" requireSelection="true" /> <s:Label id="listSelectedItem" text="{list.selectedItem}" /> <s:Label id="listSelectedIndex" text="{list.selectedIndex}" /> <s:Button label="Flip" click="flipLast()" /> </s:VGroup> </s:Application> Scenario 1: dataProvider updated, but selectedIndex is the same. At startup: [ listSelectedItem=Flex, listSelectedIndex=1 ]. Click Flip: dataProvider is updated, but still [ listSelectedItem=Flex, listSelectedIndex=1 ]. Scenario 2: dataProvider updated, selectedIndex is also updated. At startup: [ listSelectedItem=Flex, listSelectedIndex=1 ]. Select Air from list: [ listSelectedItem=Air, listSelectedIndex=2 ]. Click Flip: dataProvider is updated, but still [ listSelectedItem=Catalyst, listSelectedIndex=1 ]. Seems to me that selectedItem is driven by selectedIndex. selectedItem updates only when selectedIndex updates. Shouldn't selectedItem be updated when dataProvider is updated? Is binding to selectedItem flawed?

  • Is LuaJIT really faster than every other JIT-ed dynamic languages?

    - by Gabriel Cuvillier
    According to the computer language benchmark game, the LuaJIT implementation seems to beat every other JIT-ed dynamic language (V8, Tracemonkey, PLT Scheme, Erlang HIPE) by an order of magnitude. I know that these benchmarks are not representative (as they say: "Which programming language implementations have the fastest benchmark programs?"), but this is still really impressive. In practice, is it really the case? Someone have tested that Lua implementation?

  • New functional languages

    - by AnnaR
    Functional programming has been around since at least 1958 (creation of Lisp), but is experiencing a renaissance now with old functional languages being dusted off and new functional languages being created. Which functional languages are there that are newly developed or are in the making? I realize that you can write purely functional programs in most high level languages, so with functional languages I imply languages that are specifically designed for functional programming such as F#. If you have links to tutorials, wikis or code examples I encourage you to add them to your answer!

  • Channel Audio from .mp4?

    - by Kyle
    Hi there. I am at a loss here after searching around with no results. I am attempting to channel the audio specifically from an .mp4 for use in a driver. I am aware that there are programs which extract the audio from .mp4's, but I am looking for another approach without using external applications such as those.. is there any direction that someone can point me towards to solve this problem? Thanks, -K

  • Program compiled with MSVC 9 won't start on a vanilla SP3 XP

    - by jemper
    I installed XP on a virtual machine, updated it to SP3 and then tested a small program compiled with Visual C++ 2008 on my real computer - however it didn't start but outputted only an error saying that a problem had been detected and that a reinstall of the application (mine is 10KB in size and doesn't even have an installation) could fix the problem. What is required to run programs compiled with MSVC 9? Can I just include some dlls for it to work everywhere?

  • Win32 API prevent standby

    - by bobobobo
    What is the Win32 api function that prevents the system from going into standby? Some programs use it, which is pretty annoying in my opinion. I know there's a couple of WM_SYSCOMMAND messages you can trap to prevent the screensaver from coming on..

  • Dependency Property Set Priority: CodeBehind vs. XAML

    - by LukePet
    When I initialize a control property from code, the binding to the same property defined on XAML don't work. Why? For Example, I set control properties on startup with this statements: myControl.SetValue(UIElement.VisibilityProperty, DefaultProp.Visibility); myControl.SetValue(UIElement.IsEnabledProperty, DefaultProp.IsEnabled); and on xaml I bind the property of myControl in this way: IsEnabled="{Binding Path=IsKeyControlEnabled}" now, when the property "IsKeyControlEnabled" changes to false, myControl remains enabled (because it's initialize with true value). How can I do?
