  • Visual Studio code metrics misreporting lines of code

    - by Ian Newson
    The code metrics analyser in Visual Studio, as well as the code metrics power tool, report the number of lines of code in the TestMethod method of the following code as 8. At the most, I would expect it to report lines of code as 3. [TestClass] public class UnitTest1 { private void Test(out string str) { str = null; } [TestMethod] public void TestMethod() { var mock = new Mock<UnitTest1>(); string str; mock.Verify(m => m.Test(out str)); } } Can anyone explain why this is the case? Further info After a little more digging I've found that removing the out parameter from the Test method and updating the test code causes LOC to be reported as 2, which I believe is correct. The addition of out causes the jump, so it's not because of braces or attributes. Decompiling the DLL with dotPeek reveals a fair amount of additional code generated because of the out parameter which could be considered 8 LOC, but removing the parameter and decompiling also reveals generated code, which could be considered 5 LOC, so it's not simply a matter of VS counting compiler generated code (which I don't believe it should do anyway).

  • C++ stack in Objective-C++

    - by helixed
    I'd like to use a C++ stack type in Objective-C, but I'm running into some issues. Here's a sample of what I would like to do: #import <stack> #import <UIKit/UIKit.h> @interface A : NSObject { stack<SEL> selectorStack; } @end Unfortunately, this doesn't compile. After messing around with the code for a while and trying different things, I can't seem to find a way to accomplish this. Can somebody tell me the best way to use a C++ stack within an Objective-C object or if it's even possible? Thanks. UPDATE: Well, KennyTM's answer worked on my example file, but for some reason when I tried to rename the class it quit working. Here's the code I have right now: #import <stack> #import <UIKit/UIKit.h> @interface MenuLayer : NSObject { std::stack<SEL> selectorStack; } @end The compiler spits out the following errors: stack: No such file or directory expected specifier-qualifier-list before 'std'

  • x86 CMP Instruction Difference

    - by Pindatjuh
    Question What is the (non-trivial) difference between the following two x86 instructions? 39 /r CMP r/m32,r32 Compare r32 with r/m32 3B /r CMP r32,r/m32 Compare r/m32 with r32 Background I'm building a Java assembler, which will be used by my compiler's intermediate language to produce Windows-32 executables. Currently I have following code: final ModelBase mb = new ModelBase(); // create new memory model mb.addCode(new Compare(Register.ECX, Register.EAX)); // add code mb.addCode(new Compare(Register.EAX, Register.ECX)); // add code final FileOutputStream fos = new FileOutputStream(new File("test.exe")); mb.writeToFile(fos); fos.close(); To output a valid executable file, which contains two CMP instruction in a TEXT-section. The executable outputted to "text.exe" will do nothing interesting, but that's not the point. The class Compare is a wrapper around the CMP instruction. The above code produces (inspecting with OllyDbg): Address Hex dump Command 0040101F |. 3BC8 CMP ECX,EAX 00401021 |. 3BC1 CMP EAX,ECX The difference is subtle: if I use the 39 byte-opcode: Address Hex dump Command 0040101F |. 39C1 CMP ECX,EAX 00401021 |. 39C8 CMP EAX,ECX Which makes me wonder about their synonymity and why this even exists.

  • What's with the love of dynamic Languages

    - by Kibbee
    It seems that everybody is jumping on the dynamic, non-compiled bandwagon lately. I've mostly only worked in compiled, static typed languages (C, Java, .Net). The experience I have with dynamic languages is stuff like ASP (Vb Script), JavaScript, and PHP. Using these technologies has left a bad taste in my mouth when thinking about dynamic languages. Things that usually would have been caught by the compiler such as misspelled variable names and assigning an value of the wrong type to a variable don't occur until runtime. And even then, you may not notice an error, as it just creates a new variable, and assigns some default value. I've also never seen intellisense work well in a dynamic language, since, well, variables don't have any explicit type. What I want to know is, what people find so appealing about dynamic languages? What are the main advantages in terms of things that dynamic languages allow you to do that can't be done, or are difficult to do in compiled languages. It seems to me that we decided a long time ago, that things like uncompiled asp pages throwing runtime exceptions was a bad idea. Why is there is a resurgence of this type of code? And why does it seem to me at least, that Ruby on Rails doesn't really look like anything you couldn't have done with ASP 10 years ago?

  • Using graphical ActiveX (COM) controls in WinForms project

    - by alex
    I have a collection (set) of ActiveX controls. I recieved them from our vendor company. I created a wrappers for them using tlbimp.exe and aximp.exe. All non-graphical controls work good. All graphical controls don't react on some methods. When I call their methods I get: TargetInvocativeException (InnerException is null). or Attempt to read/write protected memory. Our vendor company assure that their graphical activex controls work good. But they don't provide support service, so I have to find solution of my problem alone. And some more, All graphical activex controls don't react on mouseclick or any other mouse manipulations. But documentation says: it must change the color on mouse click. Maybe, someone have same symptoms and can help me ! I googled over that problem many pages but they don't help me. Maybe it's some Visual Studio settings or compiler options ? I use VS 2005.

  • realloc() & ARC

    - by RynoB
    How would I be able to rewrite the the following utility class to get all the class string values for a specific type - using the objective-c runtime functions as shown below? The ARC documentation specifically states that realloc should be avoided and I also get the following compiler error on this this line: classList = realloc(classList, sizeof(Class) * numClasses); "Implicit conversion of a non-Objective-C pointer type 'void *' to '__unsafe_unretained Class *' is disallowed with ARC" The the below code is a reference to the original article which can be found here. + (NSArray *)classStringsForClassesOfType:(Class)filterType { int numClasses = 0, newNumClasses = objc_getClassList(NULL, 0); Class *classList = NULL; while (numClasses < newNumClasses) { numClasses = newNumClasses; classList = realloc(classList, sizeof(Class) * numClasses); newNumClasses = objc_getClassList(classList, numClasses); } NSMutableArray *classesArray = [NSMutableArray array]; for (int i = 0; i < numClasses; i++) { Class superClass = classList[i]; do { superClass = class_getSuperclass(superClass); if (superClass == filterType) { [classesArray addObject:NSStringFromClass(classList[i])]; break; } } while (superClass); } free(classList); return classesArray; } Your help will be much appreciated.

  • Calculation Expression Parser with Nesting and Variables in ActionScript

    - by yuletide
    Hi There, I'm trying to enable dynamic fields in the configuration file for my mapping app, but I can't figure out how to parse the "equation" passed in by the user, at least not without writing a whole parser from scratch! I'm sure there is some easier way to do this, and so I'm asking for ideas! Basic idea: public var testString:String = "(#TOTPOP_CY#-#HISPOP_CY#)/#TOTPOP_CY#"; public var valueObject:Object = {TOTPOP_CY:1000, HISPOP_CY:100}; public function calcParse(eq:String):String { // do calculations return calculatedValue } So far, I was thinking of splitting the expression by either the operators, or maybe the variable tokens, but that gets rid of the parenthetical nesting. Alternatively, use a series of regex to search and replace each piece of the expression with its value, recursively running until only a number is left. But I don't think regex does math (i.e. replace "\d + \d" with the sum of the two numbers) Ideally, I'd just do a find/replace all variable names with their values, then run an eval(), but there's no eval in AS... eesh I downloaded some course materials for a course on compiler design, so maybe I'll just write a full-fledged calculator language and parser and port it over from the OTHER flex (the parser generator) :-D

  • appengine local datastore integration testing with spring

    - by mirror303
    Hi all, I want to write some integration tests to see how my spring-managed DAO's behave when talking to the appengine datastore. Following the spring manual I will be providing my test-classes with the proper annotations: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:applicationContext.xml" }) After a lot of browsing I found this blog post dating back to august '09 from somebody doing exactly what I want to achieve. It involves writing a TestEnvironment class that implements ApiProxy.Environment plus talking to ApiProxyLocalImpl. However, if I look at the current docs (for version 1.3.1), it seems that this has been replaced by newing an instance of the framework provided LocalDatastoreServiceTestConfig which is passed to a LocalServiceTestHelper. It is too bad that the appengine docs don't show an example how to do this with JPA because then the spring wiring would be trivial. Trying to follow the route outlined in the blog posting has me running into a compiler messages telling me that classes such as ApiProxyLocalImpl are not visible by me. Hence, there must be a new way of doing it, which probably involves the LocalServiceTestHelper. My question: Does anybody know how? I know I will need to configure an EntityManagerFactory and provide it with the Datastore connection somehow... but how? :)

  • How do I create a multi-level TreeView using F#?

    - by TwentyMiles
    I would like to display a directory structure using Gtk# widgets through F#, but I'm having a hard time figuring out how to translate TreeViews into F#. Say I had a directory structure that looks like this: Directory1 SubDirectory1 SubDirectory2 SubSubDirectory1 SubDirectory3 Directory2 How would I show this tree structure with Gtk# widgets using F#? EDIT: gradbot's was the answer I was hoping for with a couple of exceptions. If you use ListStore, you loose the ability to expand levels, if you instead use : let musicListStore = new Gtk.TreeStore([|typeof<String>; typeof<String>|]) you get a layout with expandable levels. Doing this, however, breaks the calls to AppendValues so you have to add some clues for the compiler to figure out which overloaded method to use: musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) Note that the columns are explicitly passed as an array. Finally, you can nest levels even further by using the ListIter returned by Append Values let iter = musicListStore.AppendValues ("Dance") let subiter = musicListStore.AppendValues (iter, [|"Fannypack" ; "Nu Nu (Yeah Yeah) (double j and haze radio edit)"|]) musicListStore.AppendValues (subiter, [|"Some Dude"; "Some Song"|]) |> ignore

  • Scaling Literate Programming?

    - by Tetha
    Greetings. I have been looking at Literate Programming a bit now, and I do like the idea behind it: you basically write a little paper about your code and write down as much of the design decisions, the code probably surrounding the module, the inner workins of the module, assumptions and conclusions resulting from the design decisions, potential extension, all this can be written down in a nice way using tex. Granted, the first point: it is documentation. It must be kept up-to-date, but that should not be that bad, because your change should have a justification and you can write that down. However, how does Literate Programming Scale to a larger degree? Overall, Literate Programming is still just text. Very human readable text, of course, but still text, and thus, it is hard to follow large systems. For example, I reworked large parts of my compiler to use and some magic to chain compile steps together, because some "x.register_follower(y); y.register_follower(z); y.register_follower(a);..." got really unwieldy, and changing that to x y z a made it a bit better, even though this is at its breaking point, too. So, how does Literate Programming scale to larger systems? Does anyone try to do that? My thought would be to use LP to specify components that communicate with each other using event streams and chain all of these together using a subset of graphviz. This would be a fairly natural extension to LP, as you can extract a documentation -- a dataflow diagram -- from the net and also generate code from it really well. What do you think of it? -- Tetha.

  • What do I need for development for an ARM processor?

    - by claws
    Hello, I'm familiar with X86[-64] architecture & assembly. I want to start develop for an ARM processor. But unlike desktop processors, I don't have an actual ARM processor. I think I need an ARM simulator. http://www.armtutorial.com/ say An ARM assembly compiler will be required, the most accessible is the ARMulator. I thought of downloading Armulator but found from http://forums.arm.com/index.php?showtopic=13744 that Its not sold seperately. But you can download an eval of RVDS - which includes RVISS/ARMulator I've downloaded & installed RVDS but It looks very complex. I'm unable to figure out what do I need to do to write ARM assembly & run it. I want to write in assembly not in C/C++. I don't have an ARM processor. What is a good simulator? Can any one please mention in short. How to write assembly & assemble & simulate using RVDS. Please be clear? Are there any other alternative ways. I can't afford buying any kind of boards. I always learn from books rather than tutorials. I'm following these two books: ARM System Developer's Guide: Designing and Optimizing System Software (The Morgan Kaufmann Series in Computer Architecture and Design) ARM System-on-Chip Architecture (2nd Edition) Do you have any better suggestions?

  • Cast to delegate type fails in JScript.NET

    - by dnewcome
    I am trying to do async IO using BeginRead() in JScript.NET, but I can't get the callback function to work correctly. Here is the code: function readFileAsync() { var fs : FileStream = new FileStream( 'test.txt', FileMode.Open, FileAccess.Read ); var result : IAsyncResult = fs.BeginRead( new byte[8], 0, 8, readFileCallback ), fs ); Thread.Sleep( Timeout.Infinite ); } var readFileCallback = function( result : IAsyncResult ) : void { print( 'ListenerCallback():' ); } The exception is a cast failure: Unhandled Exception: System.InvalidCastException: Unable to cast object of type 'Microsoft.JScript.Closure' to type 'System.AsyncCallback'. at JScript 0.readFileAsync(Object this, VsaEngine vsa Engine) at JScript 0.Global Code() at JScript Main.Main(String[] ) I have tried doing an explicit cast both to AsyncCallback and to the base MulticastDelegate and Delegate types to no avail. Delegates are supposed to be created automatically, obviating the need for creating a new AsyncCallback explicitly, eg: BeginRead( ... new AsyncDelegate( readFileCallback), object ); And in fact if you try to create the delegate explicitly the compiler issues an error. I must be missing something here.

  • What are the primitive Forth operators?

    - by Barry Brown
    I'm interested in implementing a Forth system, just so I can get some experience building a simple VM and runtime. When starting in Forth, one typically learns about the stack and its operators (DROP, DUP, SWAP, etc.) first, so it's natural to think of these as being among the primitive operators. But they're not. Each of them can be broken down into operators that directly manipulate memory and the stack pointers. Later one learns about store (!) and fetch (@) which can be used to implement DUP, SWAP, and so forth (ha!). So what are the primitive operators? Which ones must be implemented directly in the runtime environment from which all others can be built? I'm not interested in high-performance; I want something that I (and others) can learn from. Operator optimization can come later. (Yes, I'm aware that I can start with a Turing machine and go from there. That's a bit extreme.) Edit: What I'm aiming for is akin to bootstrapping an operating system or a new compiler. What do I need do implement, at minimum, so that I can construct the rest of the system out of those primitive building blocks? I won't implement this on bare hardware; as an educational exercise, I'd write my own minimal VM.

  • Typecasting EnityObject

    - by AJ
    Hello, I'm new to C# and am stuck on the following. I have a Silverlight web service that uses LINQ to query a ADO.NET entity object. e.g.: [OperationContract] public List<Customer> GetData() { using (TestEntities ctx = new TestEntities()) { var data = from rec in ctx.Customer select rec; return data.ToList(); } } This works fine, but what I want to do is to make this more abstract. The first step would be to return a List<EntityObject> but this gives a compiler error, e.g.: [OperationContract] public List<EntityObject> GetData() { using (TestEntities ctx = new TestEntities()) { var data = from rec in ctx.Customer select rec; return data.ToList(); } } The error is: Error 1 Cannot implicitly convert type 'System.Collections.Generic.List<SilverlightTest.Web.Customer>' to 'System.Collections.Generic.IEnumerable<System.Data.Objects.DataClasses.EntityObject>'. An explicit conversion exists (are you missing a cast?) What am i doing wrong? Thanks, AJ

  • Maven doesn't compile target/hibernate3/generated-sources

    - by mmm
    Can someone tell me how to configure maven for it also to compile sources from the target/hibernate3/generated-sources directory? I have already read this and other posts but they don't seem to solve my problem (which indeed seems trivial). I have used the bottom-up approach hibernate configuration for cfg.xml, hbm.xml and POJO generation (i.e. auto-generated the complete hibernate configuration out of an existing database schema). I'm also only using standard maven and hibernate3-plugin directory layouts. Yet, when executing mvn compile in the command-line while my sources are in the src/main/java and the generated sources in /target/hibernate3/generated-sources only the ones from src/main/java get compiled and copied into target/classes. I wouldn't like to generate sources into src/main/java as I'd like mvn clean to clean them. I'd like to solve the problem using command-line, plugins and pom.xml only. Is there a way to configure maven-compiler-plugin to do so? Or is there another way? Regards and thanks for any help.

  • Do overlays/tooltips work correctly in Emacs for Windows?

    - by Cheeso
    I'm using Flymake on C# code, emacs v22.2.1 on Windows. The Flymake stuff has been working well for me. For those who don't know, you can read an overview of flymake, but the quick story is that flymake repeatedly builds the source file you are currently working on in the background, for the purpose of doing syntax checking. It then highlights the compiler warnings and erros in the current buffer. Flymake didn't work for C# initially, but I "monkey-patched it" and it works nicely now. If you edit C# in emacs, I highly recommend using flymake. The only problem I have is with the UI. Flymake highlights the errors and warnings nicely, and then inserts "overlays" with the full error or warning text. IF I hover the mouse pointer over the highlighted line in code, the overlay pops up. But as you can see, the overlay (tooltip) is truncated, and it doesn't display correctly. Flymake seems to be doing the right thing, it's the overlay part that seems broken., and overlay seems to do the right thing. It's the tooltip that is displayed incorrectly. Do overlays tooltips work correctly in emacs for Windows? Where do I look to fix this?

  • Compiling Visual c++ programs from the command line and msvcr90.dll

    - by Stanley kelly
    Hi, When I compile my Visual c++ 2008 express program from inside the IDE and redistribute it on another computer, It starts up fine without any dll dependencies that I haven't accounted for. When I compile the same program from the visual c++ 2008 command line under the start menu and redistribute it to the other computer, it looks for msvcr90.dll at start-up. Here is how it is compiled from the command line cl /Fomain.obj /c main.cpp /nologo -O2 -DNDEBUG /MD /ID:(list of include directories) link /nologo /SUBSYSTEM:WINDOWS /ENTRY:mainCRTStartup /OUT:Build\myprogram.ex e /LIBPATH:D:\libs (list of libraries) and here is how the IDE builds it based on the relevant parts of the build log. /O2 /Oi /GL /I clude" /I (list of includes) /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_UNICODE" /D "UNICODE" /FD /EHsc /MD /Gy /Yu"stdafx.h" /Fp"Release\myprogram" /Fo"Release\\" /Fd"Release\vc90.pdb" /W3 /c /Zi /TP /wd4250 /vd2 Creating command line "cl.exe @d:\myprogram\Release\RSP00000118003188.rsp /nologo /errorReport:prompt" /OUT:"D:\myprgram\Release\myprgram.exe" /INCREMENTAL:NO /LIBPATH:"d:\gtkmm\lib" /MANIFEST /MANIFESTFILE:"Release\myprogam.exe.intermediate.manifest" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /PDB:"d:\myprogram\Release\myprogram.pdb" /SUBSYSTEM:WINDOWS /OPT:REF /OPT:ICF /LTCG /ENTRY:"mainCRTStartup" /DYNAMICBASE /NXCOMPAT /MACHINE:X86 (list of libraries) Creating command line "link.exe @d:\myprogram\Release\RSP00000218003188.rsp /NOLOGO /ERRORREPORT:PROMPT" /outputresource:"..\Release\myprogram.exe;#1" /manifest .\Release\myprogram.exe.intermediate.manifest Creating command line "mt.exe @d:\myprogram\Release\RSP00000318003188.rsp /nologo" I would like to be able to compile it from the command line and not have it look for such a late version of the runtime dll, like the version compiled from the IDE seems not to do. Both versions pass /MD to the compiler, so i am not sure what to do.

  • Possible Data Execution Prevention problem in Windows 7

    - by Joel in Gö
    I have a serious problem with my .Net program. It calls a native dll, and then crashes instantly because it can't find a native method. This is behaviour we have seen before, whereby the C# compiler, in its infinite wisdom, sets the flag that the program is DEP compatible, even if it calls a native dll which patently is not. We have the standard workaround for this, where the flag is set to Not DEP Compatible in a post-build step, and this works fine. Everywhere except on my machine. I have Windows 7 32bit, and the program works fine on the Win 7 64bit machines that we have, as well as on Vista and XP; we have not yet been able to check on another Win7 32bit. However, on my machine the DataExecutionPolicy_SupportPolicy is 0, i.e. we have successfully switched DEP off. The dll in question also works fine when called from a native program. We are running out of ideas... any help would be much appreciated!
