  • What exactly are signals and slots in Qt?

    - by Jen
    I know how they work conceptually, but how are signals and slots implemented in the Qt framework? Qt Creator treats them as keywords, but are they simply a set of macros, or is a special pre-processor required before these source files can be compiled? In other words, if I use Qt's signal/slot features in my code, can I easily compile it on any C++ compiler?

  • Is .NET a write once, run anywhere (WORA) platform like Java claims to be?

    - by Scott Saad
    I remember Sun's slogan so vividly... "Write Once, Run Anywhere". The idea being that since programs are compiled into standard byte codes, any device with a Java Virtual Machine could run it. Over the years, Java seems to have made it onto many platforms/devices. Is this the intention or was it ever the intention of .NET. If so, what kind of efforts are being put forth to make this a reality?

  • delphi 7 SOAP application stop compiling

    - by FrancisR
    Hello there, I don't know why, but a SOAP Server application and a pair of clients of this services stop compiling without any know causes for me. I have installed delphi 2007 and delphi 2009 and I don't know if the cause can come from this. Now when I compile a soap application I get an error like: 'Unit XMLSchema was compiled with a different version of XMLDOM.SHttp' Someone known the cause?

  • Manual alternative to mod_deflate

    - by Bobby Jack
    Say I don't have mod_deflate compiled into apache, and I don't feel like recompiling right now. What are the downsides to a manual approach, e.g. something like: AddEncoding x-gzip .gz RewriteCond %{HTTP_ACCEPT_ENCODING} gzip RewriteRule ^/css/styles.css$ /css/styles.css.gz (Note: I'm aware that the specifics of that RewriteCond need to be tweaked slightly)

  • comprehensive list of unsafe functions in C

    - by Dervin Thunk
    Hello. I've been looking online unsuccessfully for a comprehensive list of unsafe (dangerous) functions in C (see here for a few). When I say "dangerous" I mean functions like gets or strcopy, but I was wondering if someone has actually compiled a comprehensive list. Thank you. PD: Neil Butterworth, you should abstain from answering my posts. You're seldom helpful.

  • A continued saga of C# interoprability with unmanaged C++

    - by Gilad
    After a day of banging my head against the wall both literally and metaphorically, I plead for help: I have an unmanaged C++ project, which is compiled as a DLL. Let's call it CPP Project. It currently works in an unmanaged environment. In addition, I have created a WPF project, that shall be called WPF Project. This project is a simple and currently almost empty project. It contains a single window and I want it to use code from Project 1. For that, I have created a CLR C++ project, which shall be called Interop Project and is also compiled as a DLL. For simplicity I will attach some basic testing code I have boiled down to the basics. CPP Project has the following two testing files: tester.h #pragma once extern "C" class __declspec(dllexport) NativeTester { public: void NativeTest(); }; tester.cpp #include "tester.h" void NativeTester::NativeTest() { int i = 0; } Interop Project has the following file: InteropLib.h #pragma once #include <tester.h> using namespace System; namespace InteropLib { public ref class InteropProject { public: static void Test() { NativeTester nativeTester; nativeTester.NativeTest(); } }; } Lastly, WPF Project has a single window refrencing Interop Project: MainWindow.xaml.cs using System; using System.Windows; using InteropLib; namespace AppGUI { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); InteropProject.Test(); } } } And the XAML itself has an empty window (default created). Once I am trying to run the WPF project, I get the following error: System.Windows.Markup.XamlParseException: 'The invocation of the constructor on type 'AppGUI.MainWindow' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'. --- System.IO.FileNotFoundException: Could not load file or assembly 'InteropLib.dll' or one of its dependencies. The specified module could not be found. at AppGUI.MainWindow..ctor() Interestingly enough, if I do not export the class from CPP Project, I do not get this error. Say, if i change tester.h to: #pragma once class NativeTester { public: void NativeTest() { int i = 0; } }; However, in this case I cannot use my more complex classes. If I move my implementation to a cpp file like before, I get unresolved linkage errors due to my not exporting my code. The C++ code I want to actually use is large and has many classes and is object oriented, so I can't just move all my implementation to the h files. Please help me understand this horrific error I've been trying resolve without success. Thanks.

  • How to create dependencies in automake?

    - by Sam
    Hello, I have a Makefile.am file right now that looks like this: lib_LIBRARIES = foo.a foo_a_SOURCES = bar.F90 baz.F90 When compiled, bar.F90 gives bar.o. However, bar.F90 depends on several other Fortran files (cat.F90, dog.F90, pig.F90). I want to set up Automake to rebuild bar.o if the source of one of these dependencies change. I've been reading the GNU manuals for automake/autoconf and was unable to find a solution to this. Thanks for reading.

  • How does assembly language interact with something like the Internet?

    - by Maulrus
    So I was thinking about languages the other day, and it struck me that any program written in a compiled language that interacts with the Internet is then translated into assembly that has to interact with the Internet. I've just begun learning a bit of x86 assembly to help me understand C++ a bit better, and I'm baffled by how something so low-level could do something like access the Internet. I'm sure the full answer to this question is much more than would fit in a SO answer, but could somebody give me maybe a basic summary?

  • gcc segmentation fault compiling 20k file

    - by aaa
    hi. I have fairly large file, 20k lines long (auto generated). It has been compiling okay, but after adding new if/endif preprocessor block, I started getting gcc internal errors: segmentation fault. the code inside new preprocessor block is not being compiled, so I am not sure where the error is coming from. my only guess is memory, but as far as I can tell it does not exhaust computer memory. Any thoughts?

  • If Then Statement Condition Being Ignored With Optimisations On

    - by Matma
    I think im going mad but can some show me what im missing, it must be some stupidly simple i just cant see the wood for the trees. BOTH side of this if then else statement are being executed? Ive tried commenting out the true side and moving the condition to a seperate variable with the same result. However if i explicitly set the condition to 1=0 or 1=1 then the if then statement is operating as i would expect. i.e. only executing one side of the equation... The only time ive seen this sort of thing is when the compiler has crashed and is no longer compiling (without visible indication that its not) but ive restarted studio with the same results, ive cleaned the solution, built and rebuilt with no change? please show me the stupid mistake im making using vs2005 if it matters. Dim dset As DataSet = New DataSet If (CboCustomers.SelectedValue IsNot Nothing) AndAlso (CboCustomers.SelectedValue <> "") Then Dim Sql As String = "Select sal.SalesOrderNo As SalesOrder,cus.CustomerName,has.SerialNo, convert(varchar,sal.Dateofpurchase,103) as Date from [dbo].[Customer_Table] as cus " & _ " inner join [dbo].[Hasp_table] as has on has.CustomerID=cus.CustomerTag " & _ " inner join [dbo].[salesorder_table] as sal On sal.Hasp_ID =has.Hasp_ID Where cus.CustomerTag = '" & CboCustomers.SelectedValue.ToString & "'" Dim dap As SqlDataAdapter = New SqlDataAdapter(Sql, FormConnection) dap.Fill(dset, "dbo.Customer_Table") DGCustomer.DataSource = dset.Tables("dbo.Customer_Table") Else Dim erm As String = "wtf" End If EDIT: i have found that this is something to do with the release config settings im using, i guesing its the optimisations bit. does anyone know of any utils/addons for vs that show if a line has been optimised out. delphi, my former language showed blue dots in the left margin to show that it was a compiled line, no dot meaning it wasnt compiled in, is there anything like that for vs? alternatively can someone explain how optimisations would affect this simple if statement causeing it to run both sides? EDIT2: using this thread as possible causes/solutions : http://stackoverflow.com/questions/2135509/bug-only-occurring-when-compile-optimization-enabled. It does the same with release = optimisations on, x86, x64 and AnyCPU Goes away with optimisations off. Im using V2005 on a x64 win7 machine, if that matters. Thanks

  • is there difference between debug and release reference path while compiling?

    - by Nair
    I am building a SL3 + RIA application in VS2008. When compiled the application in debug mode it compiles fine with out any error, but when I compile the same application with out any code change in release mode I get an error 'The type of namespace name 'BusyIndicator' does not exist in the namespace 'System.Windows.Controls' (are you missing an assembly reference). All the errors are coming from the generated code name.g.cs Just curious anyone run into this problem.

  • Detecting that a MemberExpression has a value

    - by cs
    How do I detect if a MemberExpression has a value that needs to be compiled/evaluated? I have two separate member expression outputs, the first which has a value, and the second which doesn't. What is the best way to differentiate between the two? exp **{value(Microsoft.Connect.Api.Client.Tests.SearchQueryUnitTests+<>c__DisplayClass6).handle}** [System.Linq.Expressions.MemberExpression]: **{value(Microsoft.Connect.Api.Client.Tests.SearchQueryUnitTests+<>c__DisplayClass6).handle}** NodeType: MemberAccess Type: {Name = "String" FullName = "System.String"} vs exp {x.CreatedBy} [System.Linq.Expressions.MemberExpression]: {x.CreatedBy} NodeType: MemberAccess Type: {Name = "String" FullName = "System.String"}

  • Any difference in performance/compatibility of different languages in PostgreSQL?

    - by Igor
    In nowadays the PostgreSQL offers plenty of procedural languages: pl/pgsql, pl/perl, etc Are there any difference in the speed/memory consumption in procedures written in different languages? Does anybody have done any test? Is it true that to use the native pl/pgsql is the most correct choice? How the procedure written in C++ and compiled into loadable module differs in all parameter w.r.t. the user function written with pl/* languages?

  • SerialVersionUID with "private static final long" still gets InvalidClassException

    - by Buggieboy
    I have compiled and jarred the various projects in my Java application, generating serialVersionUIDs automatically through Eclipse for all my classes derived from Serializable. I read the answers to this question, and verified that serialVersionUids are all private static final long. Nevertheless, I get an error like this when I try to run: java.io.InvalidClassException: com.acme.product.Widget; local class incompatible: stream classdesc serialVersionUID = 5226096973188250357, local class serialVersionUID = -5432967318654384362 What am I missing?
