Using IIS Application Request Routing (ARR) for ASP.NET MVC

- by Malcolm Frexner

I use a simple ASP.NET MVC web (the template you use when you create a new site) and the web works as expected in my live environment. I now try to use IIS Application Request Routing version 2. I have a rule that send all reuqests to a different server that match a rule. The settings are a bit like this: http://blogs.iis.net/wonyoo/archive/2008/07/09/application-request-routing-arr-as-a-reverse-proxy.aspx My rule is just a bit different it is /shop(.*). Only requests that contain shop are send to a different server. I have to use rewrite, not redirect (The same as in the Picture) This works as long as the web the original requests go to is no ASP.NET MVC web. I tried to use a plain htm file in the webfolder and it worked. If put a compiled ASP.NET application into the webfolder it worked. But as soon as I put an ASP.NET MVC web into the folder, request arr served by this application. My understanding is that the ARR should kick in before the web application gets the chance to handle the request. Did anybody use ARR sucessfully as a reverse proxy for a ASP.NET MVC web? EDIT Here is the resulting web config when the rewrite roule is entered. With this rule I get a 404 that indicates that the rule is not used. <?xml version="1.0" encoding="UTF-8"?> <configuration> <configSections> <sectionGroup name="system.web.extensions"

Building Dynamic Classes in Objective C

- by kjell_

I'm a somewhat competent ruby programmer. Yesterday I decided to finally try my hand with Apple's Cocoa frameworks. Help me see things the ObjC way? I'm trying to get my head around objc_allocateClassPair and objc_registerClassPair. My goal is to dynamically generate a few classes and then be able to use them as I would any other class. Does this work in Obj C? Having allocated and registered class A, I get a compile error when calling [[A alloc] init]; (it says 'A' Undeclared). I can only instantiate A using runtime's objc_getClass method. Is there any way to tell the compiler about A and pass it messages like I would NSString? A compiler flag or something? I have 10 or so other classes (B, C, …), all with the same superclass. I want to message them directly in code ([A classMethod], [B classMethod], …) without needing objc_getClass. Am I trying to be too dynamic here or just botching my implementation? It looks something like this… NSString *name = @"test"; Class newClass = objc_allocateClassPair([NSString class], [name UTF8String], 0); objc_registerClassPair(newClass); id a = [[objc_getClass("A") alloc] init]; NSLog(@"new class: %@ superclass: %@", a, [a superclass]); //[[A alloc] init]; blows up.

Reading some questions here on SO about conversion operators and constructors got me thinking about the interaction between them, namely when there is an 'ambiguous' call. Consider the following code: class A; class B { public: B(){} B(const A&) //conversion constructor { cout << "called B's conversion constructor" << endl; } }; class A { public: operator B() //conversion operator { cout << "called A's conversion operator" << endl; return B(); } }; int main() { B b = A(); //what should be called here? apparently, A::operator B() return 0; } The above code displays "called A's conversion operator", meaning that the conversion operator is called as opposed to the constructor. If you remove/comment out the operator B() code from A, the compiler will happily switch over to using the constructor instead (with no other changes to the code). My questions are: Since the compiler doesn't consider B b = A(); to be an ambiguous call, there must be some type of precedence at work here. Where exactly is this precedence established? (a reference/quote from the C++ standard would be appreciated) From an object-oriented philosophical standpoint, is this the way the code should behave? Who knows more about how an A object should become a B object, A or B? According to C++, the answer is A -- is there anything in object-oriented practice that suggests this should be the case? To me personally, it would make sense either way, so I'm interested to know how the choice was made. Thanks in advance

Visual Studio 2010 Can no longer build .NET v3.5

- by Adam Driscoll

I have a 2010 project that is targeting .NET v3.5. Inexplicably I can no longer build v3.5 projects. The project doesn't have ANY references added. It won't even let me add a reference to System.Core as it is added by the 'build system'. warning CS1685: The predefined type 'System.Func' is defined in multiple assemblies in the global alias; using definition from 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' IFilter.cs(82,49): error CS0433: The type 'System.Func' exists in both 'c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll' and 'c:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.dll' Looks like something is grabbing onto 4.0 but I'm not quite sure how to fix it. Any one else run into this? Coworker had this same issue. It took a reinstall of Windows to correct the problem I've opened a bug on this one: https://connect.microsoft.com/VisualStudio/feedback/details/558245/warning-cs1685-when-compiling-a-v3-5-net-application-in-visual-studio-2010 If the compiler is set to verbose I see this: FrameworkPathOverride = C:\Windows\Microsoft.NET\Framework\v4.0.30319 which is defined as: Specifies the location of mscorlib.dll and microsoft.visualbasic.dll. This parameter is equivalent to the /sdkpath switch of the vbc.exe compiler. Some other interesting tidbits: I've created a new project all together and cannot build v3.5 at all. I can build 2.0, 3.0, 3.5 Client Profile, 4.0 and 4.0 Client Profile with no problem. VB.NET can build v3.5 but C# cannot. I've tried a reinstall of .NET 3.5, 4.0 and Visual Studio 2010 with no success. Visual Studio debug logs shown nothing interesting and Safe Mode does not work. Trying to avoid a Windows reinstall...

Force x86 CLR on 'Any CPU' .NET assembly

- by jeffora

In .NET, the 'Platform Target: Any CPU' compiler option allows a .NET assembly to run as 64bit on a x64 machine, and 32bit on an x86 machine. It is also possible to force an assembly to run as x86 on an x64 machine using the 'Platform Target: x86' compiler option. Is it possible to run an assembly with the 'Any CPU' flag, but determine whether it should be run in the x86 or x64 CLR? Normally this decision is made by the CLR/OS Loader (as is my understanding) based on the bitness of the underlying system. I am trying to write a C# .NET application that can interact with (read: inject code into) other running processes. x64 processes can only inject into other x64 processes, and the same with x86. Ideally, I would like to take advantage of JIT compilation and the Any CPU option to allow a single application to be used to inject into either x64 or x86 processes (on an x64 machine). The idea is that the application would be compiled as Any CPU. On an x64 machine it would run as x64. If the target process is x86, it should relaunch itself, forcing the CLR to run it as x86. Is this possible?

Can't find compiled resource bundles

- by user351032

I am using Adobe Flash Builder 4. I've run into this issue with my latest project, but I was able to re-create it with an almost empty project. Here is what I've done. Created a new Flex Project Created a locale/en_US folder within this project. Added a class that extends SparkDownloadProgressBar. All this class does is attempt to create a Label. When I try to debug this application, I get the following error. Error: Could not find compiled resource bundle 'components' for locale 'en_US'. at mx.resources::ResourceManagerImpl/installCompiledResourceBundle()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:340] at mx.resources::ResourceManagerImpl/installCompiledResourceBundles()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:269] at mx.resources::ResourceManagerImpl/processInfo()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:387] at mx.resources::ResourceManagerImpl()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:122] at mx.resources::ResourceManager$/getInstance()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManager.as:111] at mx.core::UIComponent()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UIComponent.as:3728] at spark.components.supportClasses::TextBase()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\supportClasses\TextBase.as:154] at spark.components::Label()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\Label.as:384] at Preloader()[C:\SVN\Games\Social\Test\src\Preloader.as:21] at mx.preloaders::Preloader/initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\preloaders\Preloader.as:253] at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:1925] at mx.managers::SystemManager/initHandler()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:2419] The Flex Compiler/Additional Compiler Arguments section does contain "-locale en_US", but I do not want to just remove this as I am planning to have this load different property files based on the localization region at run-time and how I understand it, I will need to add each locale that I am planning to use on the compile argument line. I am at a loss as to how to attack this problem. If you need anymore information from me to help with this, I will be more than happy to provide it. Thanks ahead of time for the help!

Declaring struct in header file

- by wrongusername

I've been trying to include a structure called "student" in a student.h file, but I'm not quite sure how to do it. My student.h file code consists of entirely: #include<string> using namespace std; struct Student; while the student.cpp file consists of entirely: #include<string> using namespace std; struct Student { string lastName, firstName; //long list of other strings... just strings though }; Unfortunately, files that use #include "student.h" come up with numerous errors like error C2027: use of undefined type 'Student', error C2079: 'newStudent' uses undefined struct 'Student' (where newStudent is a function with a Student parameter), and error C2228: left of '.lastName' must have class/struct/union. It appears the compiler (VC++) does not recognize struct Student from "student.h" or something? I have tried declaring the whole struct in "student.h", but it didn't help either. How can I declare struct Student in "student.h" so that I can just #include "student.h" and start using the struct? BTW, it seems there are no compiler errors in student.h...

Mark assembly App_licenses.dll with AssemblyVersion (FxCop CA1016 rule)

- by user295479

Hello everyone, I'm trying to fulfil FxCop's rules in my web site. Since I use some Infragistics controls I have a licenses.licx file that turns into a "app_licenses.dll" assembly after publication. The problem is that this app_licenses.dll assembly does not comply with rule CA1016 (MarkAssembliesWithAssemblyVersion), and I should add an AssemblyVersion attribute to 'App_Licenses.dll'. I found I can add an AssemblyInfo file to my web site and then reference it from the web.config file as following: <compilers> <compiler language="c#;cs;csharp" extension=".cs" compilerOptions="C:\....\AssemblyInfo.cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4"> <providerOption name="CompilerVersion" value="v3.5" /> <providerOption name="WarnAsError" value="false" /> </compiler> </compilers> AssemblyInfo.cs contains: using System; using System.Reflection; using System.Runtime.InteropServices; using System.Resources; [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: NeutralResourcesLanguageAttribute("es-ES")] NeutralResourcesLanguageAttribute worked for another auto-generated dll in the web site (app_GlobalResources.dll) for another FxCop rule, but app_licenses.dll seems to ignore the assembly info and still pops up the same CA1016 error. Any help would be much appreciated.

Returning ifstream in a function

- by wrongusername

Here's probably a very noobish question for you: How (if at all possible) can I return an ifstream from a function? Basically, I need to obtain the filename of a database from the user, and if the database with that filename does not exist, then I need to create that file for the user. I know how to do that, but only by asking the user to restart the program after creating the file. I wanted to avoid that inconvenience for the user if possible, but the function below does not compile in gcc: ifstream getFile() { string fileName; cout << "Please enter in the name of the file you'd like to open: "; cin >> fileName; ifstream first(fileName.c_str()); if(first.fail()) { cout << "File " << fileName << " not found.\n"; first.close(); ofstream second(fileName.c_str()); cout << "File created.\n"; second.close(); ifstream third(fileName.c_str()); return third; //compiler error here } else return first; } EDIT: sorry, forgot to tell you where and what the compiler error was: main.cpp:45: note: synthesized method ‘std::basic_ifstream<char, std::char_traits<char> >::basic_ifstream(const std::basic_ifstream<char, std::char_traits<char> >&)’ first required here EDIT: I changed the function to return a pointer instead as Remus suggested, and changed the line in main() to "ifstream database = *getFile()"; now I get this error again, but this time in the line in main(): main.cpp:27: note: synthesized method ‘std::basic_ifstream<char, std::char_traits<char> >::basic_ifstream(const std::basic_ifstream<char, std::char_traits<char> >&)’ first required here

CSharpCodeProvider 'cannot find metadata file' Compiling Plugin Code With Mono

- by Jason Champion

I have some code in an XML file that I load and compile at runtime in an application. This works fine on Windows, but under Mono I get assembly reference errors. Here's the examine code in question: public static bool CompileSpell(Spell spell) { CSharpCodeProvider prov = new CSharpCodeProvider(); CompilerParameters cp = new CompilerParameters(); cp.GenerateExecutable = true; cp.GenerateInMemory = true; cp.ReferencedAssemblies.Add("system.dll"); cp.ReferencedAssemblies.Add("system.xml.dll"); cp.ReferencedAssemblies.Add("BasternaeMud.dll"); cp.ReferencedAssemblies.Add("ZoneData.dll"); Log.Trace("Compiling spell '" + spell.Name + "'."); StringBuilder sb = new StringBuilder(); int idx = spell.FileName.IndexOf('.'); string file = spell.FileName; if (idx > 0) { file = spell.FileName.Substring(0, idx); } int lines = GenerateWithMain(sb, spell.Code, "BasternaeMud"); CompilerResults cr = prov.CompileAssemblyFromSource(cp,sb.ToString()); .... The specific errors I get in the compiler results are: cannot find metadata file 'system.dll' at line 0 column 0. cannot find metadata file 'system.xml.dll' at line 0 column 0. Mono obviously doesn't like the way I add referenced assemblies to the code I'm compiling for system.xml and system.xml.dll. The other two assemblies add fine, which is no surprise because they're the code that the compiler is actually executing from and exist in the executable directory. Any clue what I need to do to fix this? Maybe I could just drop those DLLs in the executable directory, but that feels like a dumb idea.

How does one use OpenFileDialog in C# in visual Studio 2010

- by xarzu

I have written a custom dialog (form) that I can use in a C# program that behaves much like a "File - Open" menu command and brings up a window where a user can select a file or directory. The question I have is this. It has "My Computer" as its root. How can I have it so that it searches on a Network? If the file or directory is located on a network. Or better yet, in Visual Studio 2010, is there some sort of canned FileOpenDialog that I can use right away? I tried calling the OpenFileDialog as described in the example code at http://msdn.microsoft.com/en-us/library/system.windows.forms.openfiledialog.aspx but the compiler does not seem to like DialogResult.OK as used in this line of code: if(openFileDialog1.ShowDialog() == DialogResult.OK) The compiler says: Error 1 'System.Nullable' does not contain a definition for 'OK' and no extension method 'OK' accepting a first argument of type 'System.Nullable' could be found (are you missing a using directive or an assembly reference?) I tried using the namespace Microsoft.Win32 instead of System.Windows.Forms and neither worked. They both produced this error.

Why is this code invalid in C#?

- by mmattax

The following code will not compile: string foo = "bar"; Object o = foo == null ? DBNull.Value : foo; I get: Error 1 Type of conditional expression cannot be determined because there is no implicit conversion between 'System.DBNull' and 'string' To fix this, I must do something like this: string foo = "bar"; Object o = foo == null ? DBNull.Value : (Object)foo; This cast seems pointless as this is certainly legal: string foo = "bar"; Object o = foo == null ? "gork" : foo; It seems to me that when the ternary branches are of different types, the compiler will not autobox the values to the type object...but when they are of the same type then the autoboxing is automatic. In my mind the first statement should be legal... Can anyone describe why the compiler does not allow this and why the designers of C# chose to do this? I believe this is legal in Java...Though I have not verified this. Thanks. EDIT: I am asking for an understanding of why Java and C# handle this differently, what is going on underneath the scenes in C# that make this invalid. I know how to use ternary, and am not looking for a "better way" to code the examples. I understand the rules of ternary in C#, but I want to know WHY... EDIT (Jon Skeet): Removed "autoboxing" tag as no boxing is involved in this question.

How to provide stl like container with public const iterator and private non-const iterator?

- by WilliamKF

Hello, I am deriving a class privately from std::list and wish to provide public begin() and end() for const_iterator and private begin() and end() for just plain iterator. However, the compiler is seeing the private version and complaining that it is private instead of using the public const version. I understand that C++ will not overload on return type (in this case const_iterator and iterator) and thus it is choosing the non-const version since my object is not const. Short of casting my object to const before calling begin() or not overloading the name begin is there a way to accomplish this? I would think this is a known pattern that folks have solved before and would like to follow suit as to how this is typically solved. class myObject; class myContainer : private std::list<myObject> { public: typedef std::list<myObject>::const_iterator myContainer::const_iterator; private: typedef std::list<myObject>::iterator myContainer::iterator; public: myContainer::const_iterator begin() const { return std::list<myObject>::begin(); } myContainer::const_iterator end() const { return std::list<myObject>::end(); } private: myContainer::iterator begin() { return std::list<myObject>::begin(); } myContainer::iterator end() { return std::list<myObject>::end(); } }; void myFunction(myContainer &container) { myContainer::const_iterator aItr = container.begin(); myContainer::const_iterator aEndItr = container.end(); for (; aItr != aEndItr; ++aItr) { const myObject &item = *aItr; // Do something const on container's contents. } } The error from the compiler is something like this: ../../src/example.h:447: error: `std::_List_iterator<myObject> myContainer::begin()' is private caller.cpp:2393: error: within this context ../../src/example.h:450: error: `std::_List_iterator<myObject> myContainer::end()' is private caller.cpp:2394: error: within this context Thanks. -William

Primitive type 'short' - casting in Java

- by gemm

Hello, I have a question about the primitive type 'short' in Java. I am using JDK 1.6. If I have the following: short a = 2; short b = 3; short c = a + b; the compiler does not want to compile - it says that it "cannot convert from int to short" and suggests that I make a cast to short, so this: short c = (short) (a + b); really works. But my question is why do I need to cast? The values of a and b are in the range of short - the range of short values is {-32,768, 32767}. I also need to cast when I want to perform the operations -, *, / (I haven't checked for others). If I do the same for primitive type int, I do not need to cast aa+bb to int. The following works fine: int aa = 2; int bb = 3; int cc = aa +bb; I discovered this while designing a class where I needed to add two variables of type short, and the compiler wanted me to make a cast. If I do this with two variables of type int, I don't need to cast. Thank you very much in advance. A small remark: the same thing also happens with the primitive type byte. So, this workes: byte a = 2; byte b = 3; byte c = (byte) (a + b); but this not: byte a = 2; byte b = 3; byte c = a + b; For long, float, double, and int, there is no need to cast. Only for short and byte values.

Using MSADO15.DLL and C++ with MinGW/GCC on Windows Vista

- by Eugen Mihailescu

INTRODUCTION Hi, I am very new to C++, is my 1st statement. I have started initially with VC++ 2008 Express, I've notice that GCC becomes kind of standard so I am trying to make the right steps event from the beginning. I have written a piece of code that connects to MSSQL Server via ADO, on VC++ it's working like a charm by importing MSADO15.dll: #import "msado15.dll" no_namespace rename("EOF", "EndOfFile") Because I am going to move from VC++ I was looking for an alternative (eventually multi-platform) IDE, so I stick (for this time) with Code::Block (I'm using last nightly buil, SVN 6181). As compiler I choose to use GCC 3.4.5 (ported via MinGW 5.1.6), under Vista. I was trying to compile a simple "hello world" application with GCC that use/import the same msado15.dll (#import "c:\Program Files\Common Files\System\ADO\msado15.dll" no_namespace rename("EOF", "EndOfFile")) and I was surprised to see a lot of compile-time errors. I was expected that the #import compiler's directive will generate a library from "msado15.dll" so it can link to it later (link-edit time or whatever). Instead it was trying to read it as a normal file (like a header file,if you like) because it was trying to interprete each line in the DLL (which has a MZ signature): Example: Compiling: main.cpp E:\MyPath\main.cpp:2:64: warning: extra tokens at end of #import directive In file included from E:\MyPath\main.cpp:2: c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\144' in program In file included from E:\MyPath\main.cpp:2: c:\Program Files\Common Files\System\ADO\msado15.dll:1:4: warning: null character(s) ignored c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\3' in program c:\Program Files\Common Files\System\ADO\msado15.dll:1:6: warning: null character(s) ignored c:\Program Files\Common Files\System\ADO\msado15.dll:1: error: stray '\4' in program ... and so on. MY QUESTION Well, it is obvious that under this version of GCC the #import directive does not do the expected job (perhaps #import is not supported anymore by GCC), so finally my question: how to use the ADO to access MSSQL database on a C++ program compiled with GCC (v3.4.5)?

JSP or .ascx equivalent for Scala?

- by Daniel Worthington

I'm working on a small MVC "framework" (it's really very small) in Scala. I'd like to be able to write my view files as Scala code so I can get lots of help from the compiler. Pre-compiling is great, but what I really want is a way to have the servlet container automatically compile certain files (my view files) on request so I don't have to shut down Jetty and compile all my source files at once, then start it up again just to see small changes to my HTML. I do this a lot with .ascx files in .NET (the file will contain just one scriptlet tag with a bunch of C# code inside which writes out markup using an XmlWriter) and I love this workflow. You just make changes and then refresh your browser, but it's still getting compiled! I don't have a lot of experience with Java, but it seems possible to do this with JSP as well. I'm wondering if this sort of thing is possible in Scala. I have looked into building this myself (see more info here: http://www.nabble.com/Compiler-API-td12050645.html) but I would rather use something else if it's out there.

Iteration speed of int vs long

- by jqno

I have the following two programs: long startTime = System.currentTimeMillis(); for (int i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); and long startTime = System.currentTimeMillis(); for (long i = 0; i < N; i++); long endTime = System.currentTimeMillis(); System.out.println("Elapsed time: " + (endTime - startTime) + " msecs"); Note: the only difference is the type of the loop variable (int and long). When I run this, the first program consistently prints between 0 and 16 msecs, regardless of the value of N. The second takes a lot longer. For N == Integer.MAX_VALUE, it runs in about 1800 msecs on my machine. The run time appears to be more or less linear in N. So why is this? I suppose the JIT-compiler optimizes the int loop to death. And for good reason, because obviously it doesn't do anything. But why doesn't it do so for the long loop as well? A colleague thought we might be measuring the JIT compiler doing its work in the long loop, but since the run time seems to be linear in N, this probably isn't the case.

Compile error on inheritance of generic inner class extending with bounds

- by Arne Burmeister

I have a problem when compiling a generic class with an inner class. The class extends a generic class, the inner class also. Here the interface implemented: public interface IndexIterator<Element> extends Iterator<Element> { ... } The generic super class: public abstract class CompoundCollection<Element, Part extends Collection<Element>> implements Collection<Element> { ... protected class CompoundIterator<Iter extends Iterator<Element>> extends ImmutableIterator<Element> { ... } } The generic subclass with the compiler error: public class CompoundList<Element> extends CompoundCollection<Element, List<Element>> implements List<Element> { ... private class CompoundIndexIterator extends CompoundIterator<IndexIterator<Element>> implements IndexIterator<Element> { ... } } The error is: type parameter diergo.collect.IndexIterator<Element> is not within its bound extends CompoundIterator<IndexIterator<Element>> ^ What is wrong? The code compiles with eclipse, but bot with java 5 compiler (I use ant with java 5 on a mac and eclipse 3.5). No, I cannot convert it to a static inner class.

Some general C questions.

- by b-gen-jack-o-neill

Hello. I am trying to fully understand the process pro writing code in some language to execution by OS. In my case, the language would be C and the OS would be Windows. So far, I read many different articles, but I am not sure, whether I understand the process right, and I would like to ask you if you know some good articles on some subjects I couldn´t find. So, what I think I know about C (and basically other languages): C compiler itself handles only data types, basic math operations, pointers operations, and work with functions. By work with functions I mean how to pass argument to it, and how to get output from function. During compilation, function call is replaced by passing arguments to stack, and than if function is not inline, its call is replaced by some symbol for linker. Linker than find the function definition, and replace the symbol to jump adress to that function (and of course than jump back to program). If the above is generally true and I get it right, where to final .exe file actually linker saves the functions? After the main() function? And what creates the .exe header? Compiler or Linker? Now, additional capabilities of C, today known as C standart library is set of functions and the declarations of them, that other programmers wrote to extend and simplify use of C language. But these functions like printf() were (or could be?) written in different language, or assembler. And there comes my next question, can be, for example printf() function be written in pure C without use of assembler? I know this is quite big question, but I just mostly want to know, wheather I am right or not. And trust me, I read a lots of articles on the web, and I would not ask you, If I could find these infromation together on one place, in one article. Insted I must piece by piece gather informations, so I am not sure if I am right. Thanks.

Removing padding from structure in kernel module

- by dexkid

I am compiling a kernel module, containing a structure of size 34, using the standard command. make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules The sizeof(some_structure) is coming as 36 instead of 34 i.e. the compiler is padding the structure. How do I remove this padding? Running make V=1 shows the gcc compiler options passed as make -I../inc -C /lib/modules/2.6.29.4-167.fc11.i686.PAE/build M=/home/vishal/20100426_eth_vishal/organised_eth/src modules make[1]: Entering directory `/usr/src/kernels/2.6.29.4-167.fc11.i686.PAE' test -e include/linux/autoconf.h -a -e include/config/auto.conf || ( \ echo; \ echo " ERROR: Kernel configuration is invalid."; \ echo " include/linux/autoconf.h or include/config/auto.conf are missing."; \ echo " Run 'make oldconfig && make prepare' on kernel src to fix it."; \ echo; \ /bin/false) mkdir -p /home/vishal/20100426_eth_vishal/organised_eth/src/.tmp_versions ; rm -f /home/vishal/20100426_eth_vishal/organised_eth/src/.tmp_versions/* make -f scripts/Makefile.build obj=/home/vishal/20100426_eth_vishal/organised_eth/src gcc -Wp,-MD,/home/vishal/20100426_eth_vishal/organised_eth/src/.eth_main.o.d -nostdinc -isystem /usr/lib/gcc/i586-redhat-linux/4.4.0/include -Iinclude -I/usr/src/kernels/2.6.29.4-167.fc11.i686.PAE/arch/x86/include -include include/linux/autoconf.h -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Os -m32 -msoft-float -mregparm=3 -freg-struct-return -mpreferred-stack-boundary=2 -march=i686 -mtune=generic -Wa,-mtune=generic32 -ffreestanding -DCONFIG_AS_CFI=1 -DCONFIG_AS_CFI_SIGNAL_FRAME=1 -pipe -Wno-sign-compare -fno-asynchronous-unwind-tables -mno-sse -mno-mmx -mno-sse2 -mno-3dnow -Iarch/x86/include/asm/mach-generic -Iarch/x86/include/asm/mach-default -Wframe-larger-than=1024 -fno-stack-protector -fno-omit-frame-pointer -fno-optimize-sibling-calls -g -pg -Wdeclaration-after-statement -Wno-pointer-sign -fwrapv -fno-dwarf2-cfi-asm -DTX_DESCRIPTOR_IN_SYSTEM_MEMORY -DRX_DESCRIPTOR_IN_SYSTEM_MEMORY -DTX_BUFFER_IN_SYSTEM_MEMORY -DRX_BUFFER_IN_SYSTEM_MEMORY -DALTERNATE_DESCRIPTORS -DEXT_8_BYTE_DESCRIPTOR -O0 -Wall -DT_ETH_1588_051 -DALTERNATE_DESCRIPTORS -DEXT_8_BYTE_DESCRIPTOR -DNETHERNET_INTERRUPTS -DETH_IEEE1588_TESTS -DSNAPTYPSEL_TMSTRENA_TEVENTENA_TESTS -DT_ETH_1588_140_147 -DLOW_DEBUG_PRINTS -DMEDIUM_DEBUG_PRINTS -DHIGH_DEBUG_PRINTS -DMODULE -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(eth_main)" -D"KBUILD_MODNAME=KBUILD_STR(conxt_eth)" -c -o /home/vishal/20100426_eth_vishal/organised_eth/src/eth_main.o /home/vishal/20100426_eth_vishal/organised_eth/src/eth_main.c

Disable Flex CSS type selector warning?

- by davr

I'm building a somewhat large Flex project that includes several modules (a single Flex project that produces multiple SWFs) Right now, I have a single css file, being loaded in the main SWF tag: <s:Application ... > <fx:Style source="css/main.css" /> ... </s:Application> In the CSS file: /* CSS file */ @namespace s "library://ns.adobe.com/flex/spark"; s|Panel { skinClass: ClassReference("com.skins.DefaultPanelSkin"); } s|Button { skinClass: ClassReference("com.skins.DefaultButtonSkin"); } The CSS file is not referenced anywhere else. I have currently 6 modules (plus the main SWF, a total of 7 SWFs). I've noticed that the number of warnings is correlated to the number of modules...every time I add a module, I get more warnings. Right now, I get 6 warnings for every entry in the CSS file, so: CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' CSS type selectors are not supported in components: 'Panel' And repeat for Button, TextArea, etc etc. I have so many useless warnings, it is impossible to see if there are any valid ones. Is this warning caused by something I'm doing wrong? The styles are all being applied correctly and appears to work just the way I want at runtime. If I'm doing nothing wrong, can I tell the compiler to ignore this warning? NOTE: I've tried the -show-unused-type-selector-warnings=false compiler flag, and it does not work...that's for a similar but different warning.
