  • What kind of assemblies can be called using P/Invoke ?

    - by milan
    Hi all, I allready asked at: Is it possible to call unmanaged code using C# reflection from managed code ? if it is possible to call C/C++ library unmanaged function with Invoke and reflection from .NET and the answer is yes. What I am not clear about is can I call using P/Invoke ANY assembly written/compiled/build with other compilers on my Windows PC like Labwindows/CVI(have some kind of C compiler) or Java written dll's, exe. If this is possible is it the same as explained in above given link using "Marshal.GetDelegateForFunctionPointer" ? Thanks! Milan.

  • Is it possible to get code coverage data for a GWT web app running tests from the web browser?

    - by jeff
    I am not sure if this is possible but I would like some way to get code coverage information for tests that are written in Quick Test for our GWT based web app. It does not seem like there is any solution because the Quick Test Pro tests are testing against the GWT compiled app and not the original java code in which the app was written. I suppose I could get coverage data on the javascript that the GWT compiler creates, but there would be no way for me (that I know of) to map this information back to the original java code. Is there some way to do this?

  • Analyzing Windows crash dumps generated on XP/32 machines with Win7/64 ?

    - by Martin
    We have a problem with analyzing our Windows crash-dumps that were created on customer Windows XP/32 boxes on our development machines. Many of our development machines are now Win7/64 boxes, but it appears that the crash-dumps generated under Windows XP cannot full resolve their binary dependency, thereby leading to warnings when displaying the call stacks in Visual Studio (2005). For example, the msvcr80.dll cannot be resolved when loaded from a Win7 machine when the dump was generated on Windows XP: On XP, the WinSxS path appears to be C:\WINDOWS\WinSxS\x86_Microsoft.VC80.CRT_1fc8b3b9a1e18e3b_8.0.50727.4053_x-ww_e6967989\msvcr80.dll -- on Win7, the WinSxS path to the same DLL version seems to be: x86_microsoft.vc80.crt_1fc8b3b9a1e18e3b_8.0.50727.4053_none_d08d7da0442a985d (I got this info from a forum thread on codeguru that link to an msdn article.) Visual Studio (2005) can now no longer correctly resolve the binaries for the crash-dump. How can I get Visual Studio to resolve all the correct binaries for my dump file? Note: I have already correctly set up the symbol server. The public symbols for most system DLLs (kernel32.dll, etc) and our symbols of our own DLLs are correctly loaded. It is just that the symbols of DLLs that reside in the WinSxS folder are not loaded, because it appears that Vista/7 uses a different path scheme for these DLLs than XP does and therefore Visual Studio cannot find the dll (not the pdb) on the local dev machine and so cannot load the corresponding symbols for the dump file.

  • Is there a way to call custom method of Custom Role Provider class

    - by IrfanRaza
    Hello friends, I have created my own custom role provider class "SGI_RoleProvider" and configured properly. Everything is working fine. Suppose that I have added a public method say "SayHello()", then how can i call that. Because if i am using Roles then the method is not displayed. If i am forcefully using that Roles.SayHello() then compiler gives the error. Any suggestion how can i call this. Because creating a new instance of SGI_RoleProvider is meaningless. Thanks for sharing your time.

  • Is Perl's flip-flop operator bugged? It has global state, how can I reset it?

    - by Evan Carroll
    I'm dismayed. Ok, so this was probably the most fun perl bug I've ever found. Even today I'm learning new stuff about perl. Essentially, the flip-flop operator .. which returns false until the left-hand-side returns true, and then true until the right-hand-side returns false keep global state (or that is what I assume.) My question is can I reset it, (perhaps this would be a good addition to perl4-esque hardly ever used reset())? Or, is there no way to use this operator safely? I also don't see this (the global context bit) documented anywhere in perldoc perlop is this a mistake? Code use feature ':5.10'; use strict; use warnings; sub search { my $arr = shift; grep { !( /start/ .. /never_exist/ ) } @$arr; } my @foo = qw/foo bar start baz end quz quz/; my @bar = qw/foo bar start baz end quz quz/; say 'first shot - foo'; say for search \@foo; say 'second shot - bar'; say for search \@bar; Spoiler $ perl test.pl first shot foo bar second shot

  • Unable to view dialog box in win ce

    - by ame
    I have a win32 application (over 100 source files large) which i need to port to Win CE. I disabled the unsupported functions (such as non client area functions) and compiled the code on a Win CE platform. Now when i run it on my hardware device, I was able to resize the first couple of dialog screens to show up satisfactorily on the LCD. However there is a dialog box that has 2 option buttons and opens a new dialog box based on the choice. I am unable to view the new dialog box. Also, the close (X) button of the parent dialog box is not there and instead shows a question mark (?). I tried resizing the dialog box in the win32 code's resource compiler and it still showed up fine thus telling me that the problem did not lie with the bitmaps. I think there might be some issue with hiding the first dialog box or opening 2 at the same time. please help me. I did not code the win32 version myself and hence i am unable to locate the problem.

  • Catching a nested-in-template exception [C++]

    - by Karol
    Hello, I have a problem with writing a catch clause for an exception that is a class nested in a template. To be more specific, I have a following definition of the template and exception: /** Generic stack implementation. Accepts std::list, std::deque and std::vector as inner container. */ template < typename T, template < typename Element, typename = std::allocator<Element> > class Container = std::deque > class stack { public: class StackEmptyException { }; ... /** Returns value from the top of the stack. Throws StackEmptyException when the stack is empty. */ T top() const; ... } I have a following template method that I want exception to catch: template <typename Stack> void testTopThrowsStackEmptyExceptionOnEmptyStack() { Stack stack; std::cout << "Testing top throws StackEmptyException on empty stack..."; try { stack.top(); } catch (Stack::StackEmptyException) { // as expected. } std::cout << "success." << std::endl; } When I compile it (-Wall, -pedantic) I get the following error: In function ‘void testTopThrowsStackEmptyExceptionOnEmptyStack()’: error: expected type-specifier error: expected unqualified-id before ‘)’ token === Build finished: 2 errors, 0 warnings === Thanks in advance for any help! What is interesting, if the stack implementation was not a template, then the compiler would accept the code as it is.

  • All possible values of int from the smallest to the largest, using Java.

    - by Totophil
    Write a program to print out all possible values of int data type from the smallest to the largest, using Java. Some notable solutions as of 8th of May 2009, 10:44 GMT: 1) Daniel Lew was the first to post correctly working code. 2) Kris has provided the simplest solution for the given problem. 3) Tom Hawtin - tackline, came up arguably with the most elegant solution. 4) mmyers pointed out that printing is likely to become a bottleneck and can be improved through buffering. 5) Jay's brute force approach is notable since, besides defying the core point of programming, the resulting source code takes about 128 GB and will blow compiler limits. As a side note I believe that the answers do demonstrate that it could be a good interview question, as long as the emphasis is not on the ability to remember trivia about the data type overflow and its implications (that can be easily spotted during unit testing), or the way of obtaining MAX and MIN limits (can easily be looked up in the documentation) but rather on the analysis of various ways of dealing with the problem.

  • Are there macro facility for Java or C#?

    - by h2g2java
    Macros are useful. Therefore, I occasionally bemoan the absence of macros in Java and C#. Macros allow me to force in-line but allow me the code-manageability of non-macro code. Is there any Java- or C#-based project/product somewhere out there that effectively allow macros or specifying in-line expansion. I am thinking of something like @macro public void hello(int x){ ... } or when I call a method, an @inline annotation preceding the call would effect the called-method to be in-lined. or, should I need to know that I should just trust the compiler to make the best the decision for me that at the best of its analysis it might in-line a call. I hope this question will not lead to debating the pro/cons/usefulness of macros.

  • Foundation framework. No NSString.h file

    - by pawelini1
    Hello I'm getting a few errors just after I updated my working copy via SVN. /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSCharacterSet.h:8:0 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSCharacterSet.h:8:32: error: Foundation/NSString.h: No such file or directory /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSCharacterSet.h:45:0 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSCharacterSet.h:45: error: expected ')' before 'unichar' /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSPathUtilities.h:10:0 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSPathUtilities.h:10: error: cannot find interface declaration for 'NSString' All that errors tell that compiler is unable to find NSString.h file in Foundation framework and I have opened the Foundation framework in Xcode/Frameworks/Foundation.framework/Headers and noticed that there is no NSString header file there. Could anyone tell me what happened? I tried to delete the framework and add it again but it failed to. Still I don't have NSString header file.

  • Returning structs in registers - ARM ABI in GCC

    - by jbcreix
    Hi, In the ARM ABI documentation I come across functions defined like: __value_in_regs struct bar foo(int a, int b) { ... } but GCC(4.3.3) doesn't allow it and all I could find are references to some RealView compiler. Is there any way of doing this from GCC? I have tried -freg-struct-return but it doesn't make a difference. As it is an ABI I can't change the original programs, and returning a regular struct mangles the stack. I would rather not using assembly for this if avoidable as it isn't otherwise necessary. Thanks!

  • Updating PDB files without rebuilding.

    - by amit
    Hi All, Is there a way to update the PDB file with the new source location ? I have a project which links to some libraries which are built on another machine and are debug build with the PDB file. I cannot put a breakpoint in the files which are compiled in the libs. These libs take more than 4 hours to build so I dont want to buid them on my machine. Is there a way where i can make the compiler use the new source paths. I am using VS 2005 pro c++. Thanks Amit

  • Expression Tree

    - by nettguy
    My understanding of expression tree is : Expression trees are in-memory representation of expression like arithmetic or boolean expression.The expressions are stored into the parsed tree.so we can easily transalate into any other language. Linq to SQL uses expression tree.Normally in LINQ to SQL query the compiler translates it into parsed expression trees.These are passed to Sql Server as T-SQL Statements.The Sql server executes the T-SQL query and sends down the result back.That is why when you execute LINQ to SQL you gets IQueryable<T> not IEnumetrable<T>.Because IQuerybale contains public IQueryable:IEnumerable { Type Element {get;} Expression Expression {get;} IQueryaleProvider Provider {get;} } Questions : Microsoft uses Expression trees to play with LINQ-to-Sql.What are the different ways can i use expression trees to boost my code. Apart from LINQ to SQL,Linq to amazon ,who used expression trees in their applications? Linq to Object return IEnumerable,Linq to SQL return IQueryable ,What does LINQ to XML return?

  • Graphical Programming Language

    - by prosseek
    In control engineering or instrumentation, I see Simulink or LabVIEW(G) is pretty popular. In ESL design, I see that Agilent SystemVue is gaining some popularity. If you see the well established compiler theroy, almost 100% is about the textual language. But how about the graphical language? Is there any noticable research or discussion about the graphical programming language? In terms of Theory about Graphical Language - syntactic/semantic analysis and whatever relevant expressiveness (Actually, I asked a question about it at SO - http://stackoverflow.com/questions/2427496/what-do-you-mean-by-the-expressiveness-in-programming-lanuguage) Possibility of the Graphical language ... Or what do you think about the Graphical Programming Language?

  • How exactly does linking in C# work?

    - by akosch
    I want to use a GPL'd library in my C# application, but not necessarily release my own code under the GPL. If I understand correctly linking against a GPL'd library using dynamic linking and not distributing the library in question means I can license my own app in any way I want (the users of my software would then be required to install the library themselves). Please correct me if I'm wrong. My question is: how can I link against a DLL this way in C#? Do I only need to use C#'s using directive and add the DLL as a reference to the compiler? Is the distribution of the resulting bytecode legal?

  • BeautifulSoup can't parse a webpage?

    - by JLTChiu
    I am using beautiful soup for parsing webpage now, I've heard it's very famous and good, but it doesn't seems works properly. Here's what I did import urllib2 from bs4 import BeautifulSoup page = urllib2.urlopen("http://www.cnn.com/2012/10/14/us/skydiver-record-attempt/index.html?hpt=hp_t1") soup = BeautifulSoup(page) print soup.prettify() I think this is kind of straightforward. I open the webpage and pass it to the beautifulsoup. But here's what I got: Warning (from warnings module): File "C:\Python27\lib\site-packages\bs4\builder\_htmlparser.py", line 149 "Python's built-in HTMLParser cannot parse the given document. This is not a bug in Beautiful Soup. The best solution is to install an external parser (lxml or html5lib), and use Beautiful Soup with that parser.

HTMLParseError: bad end tag: u'</"+"script>', at line 634, column 94 I thought CNN website should be well designed, so I am not very sure what's going on though. Does anyone has idea about this?

Is there something I need to add to my class, or to the .pro file?

  • Xcode 3.2 + LLVM = no local symbols when debugging

    - by glebd
    I have a project for Mac OS X 10.5 that I'm building on 10.6 using Xcode 3.2. When I use GCC 4.2 for Debug build and hit a breakpoint, Xcode debugger displays local variable information normally. If I choose LLVM GCC 4.2 or Clang LLVM, when I hit breakpoint, local symbols are not available, and GDB says No symbol 'self' in current context if I try to print self or any other local symbol. In all cases Generate debug info option is set. The Debug configuration is set to $(NATIVE_ARCH) and 10.5 SDK, Build active architecture only option is set. When GDB starts, I can see it is being configured as x86_64-apple-darwin. I must be missing something obvious. How do I make GDB show local symbols when using a LLVM compiler?

  • C# Language Design: explicit interface implementation of an event

    - by ControlFlow
    Small question about C# language design :)) If I had an interface like this: interface IFoo { int Value { get; set; } } It's possible to explicitly implement such interface using C# 3.0 auto-implemented properties: sealed class Foo : IFoo { int IFoo.Value { get; set; } } But if I had an event in the interface: interface IFoo { event EventHandler Event; } And trying to explicitly implement it using field-like event: sealed class Foo : IFoo { event EventHandler IFoo.Event; } I will get the following compiler error: error CS0071: An explicit interface implementation of an event must use event accessor syntax I think that field-like events is the some kind of dualism for auto-implemented properties. So my question is: what is the design reason for such restriction done?

  • Static libraries, dynamic libraries, DLLs, entry points, headers ... how to get out of this alive?

    - by tunnuz
    Hello, I recently had to program C++ under Windows for an University project, and I'm pretty confused about static and dynamic libraries system, what the compiler needs, what the linker needs, how to build a library ... is there any good document about this out there? I'm pretty confused about the *nix library system as well (so, dylibs, the ar tool, how to compile them ...), can you point a review document about the current library techniques on the various architectures? Note: due to my poor knowledge this message could contain wrong concepts, feel free to edit it. Thank you Feel free to add more reference, I will add them to the summary. References Since most of you posted *nix or Windows specific references I will summarize here the best ones, I will mark as accepted answer the Wikipedia one, because is a good start point (and has references inside too) to get introduced to this stuff.

  • How do I specify the block object / predicate required by NSDictionary's keysOfEntriesPassingTest ?

    - by Todd
    For learning (not practical -- yet) purposes, I'd like to use the following method on an NSDictionary to give me back a set of keys that have values using a test I've defined. Unfortunately have no idea how to specify the predicate. NSDictionary keysOfEntriesPassingTest: - (NSSet *)keysOfEntriesPassingTest:(BOOL (^)(id key, id obj, BOOL *stop))predicate Let's say for example all my values are NSURLs, and I'd like to get back all the URLs that are on port 8080. Here's my stab at coding that -- though it doesn't really make sense to me that it'd be correct: NSSet * mySet = [myDict keysOfEntriesPassingTest:^(id key, id obj, BOOL *stop) { if( [[obj port] isEqual: [NSNumber numberWithInt: 8080]]) { return key; }] And that's because I get back the following compiler error: incompatible block pointer types initializing 'void (^)(struct objc_object *, struct objc_object *, BOOL *)', expected 'BOOL (^)(struct objc_object *, struct objc_object *, BOOL *)' What am I missing? I'd appreciate a pointer at some docs that go into more detail about the "Block object" that the predicate is supposed to be. Thanks!

  • Persistent warning message about "initWithDelegate"!

    - by RickiG
    Hi This is not an actual Xcode error message, it is a warning that has been haunting me for a long time. I have found no way of removing it and I think I maybe have overstepped some unwritten naming convention rule. If I build a class, most often extending NSObject, whose only purpose is to do some task and report back when it has data, I often give it a convenience constructor like "initWithDelegate". The first time I did this in my current project was for a class called ISWebservice which has a protocol like this: @protocol ISWebserviceDelegate @optional - (void) serviceFailed:(NSError*) error; - (void) serviceSuccess:(NSArray*) data; @required @end Declared in my ISWebservice.h interface, right below my import statements. I have other classes that uses a convenience constructor named "initWithDelegate". E.g. "InternetConnectionLost.h", this class does not however have its methods as optional, there are no @optional @required tags in the declaration, i.e. they are all required. Now my warning pops up every time I instantiate one of these Classes with convenience constructors written later than the ISWebservice, so when utilizing the "InternetConnectionLost" class, even though the entire Class owning the "InternetConnectionLost" object has nothing to do with the "ISWebservice" Class, no imports, methods being called, no nothing, the warning goes: 'ClassOwningInternetConnectionLost' does not implement the 'ISWebserviceDelegate' protocol I does not break anything, crash at runtime or do me any harm, but it has begun to bug me as I near release. Also, because several classes use the "initWithDelegate" constructor naming, I have 18 of these warnings in my build results and I am getting uncertain if I did something wrong, being fairly new at this language. Hope someone can shed a little light on this warning, thank you:)

  • MySQL and Matlab

    - by Shaihi
    I want to interact with a MySQL database from Matlab. I found a mysql "library" for matlab here and the same on mathworks. I followed the instructions to compile the library and the compilation seems to be successful. I get a mex32 file at the end. Only, the instructions on the first page refer to a Dll that I need to use (I guess that a Dll was supposed to be generated). I am not familiar with the mex compiler or with compiling external modules for Matlab. Am I missing something trivial? Where is the Dll supposed to be? Thanks.

  • What would cause native gem extensions on OS X to build but fail to load?

    - by goodmike
    I am having trouble with some of my rubygems, in particular those that use native extensions. I am on a MacBookPro, with Snow Leopard. I have XCode 3.2.1 installed, with gcc 4.2.1. Ruby 1.8.6, because I'm lazy and a scaredy cat and don't want to upgrade yet. Ruby is running in 32-bit mode. I built this ruby from scratch when my MBP ran OSX 10.4. When I require one of the affected gems in irb, I get a Load Error for the gem extension's bundle file. For example, here's nokogigi dissing me: > require 'rubygems' = true > require 'nokogiri' LoadError: Failed to load /usr/local/lib/ruby/gems/1.8/gems/nokogiri-1.4.1/lib/nokogiri/nokogiri.bundle This is also happening with the Postgres pg and MongoDB mongo gems. My first thought was that the extensions must not be building right. But gem install wasn't throwing any errors. So I reinstalled with the verbose flag, hoping to see some helpful warnings. I've put the output in a Pastie, and the only warning I see is a consistent one about "passing argument n of ‘foo’ with different width due to prototype." I suspect that this might be an issue from upgrading to Snow Leopard, but I'm a little surprised to experience it now, since I've updated my XCode. Could it stem from running Ruby in 1.8.6? I'm embarrassed that I don't know quite enough about my Mac and OSX to know where to look next, so any guidance, even just a pointer to some document I couldn't find via Google, would be most welcome. Michael
