• Addressing "Access Denied" Exception with WMI Calls

  - by Joe

  I'm getting an exception with a message of "Access Denied" when executing against a WMI request. Some WMI requests appear to require higher security privileges than others. Ultimately my goal is to monitor process launches within the system and log. Regardless if there is a better approach, its now become a vendetta in getting this WMI approach to work. I've attempted the code at Security Tools - WMI Programming Using C#.Net and still receive the exception. If you copy the code found in the blog entry you can reproduce my issue. Another post on a similar topic can be found at link text but again, try the code and you'll the see the same security exception. How do I permit my code to execute these WMI requests? I'm running on Windows 7 Pro and VS 2010 in a new C# command line project.

• eclipse, one classpath for compiling, another for launching

  - by DragonFax

  example: For logging, my code uses log4j. but other jars my code is dependent upon, uses slf4j instead. So both jars must be in the build path. Unfortunately, its possible for my code to directly use (depend on) slf4j now, either by context-assist, or some other developers changes. I would like any use of slf4j to show up as an error, but my application (and tests) will still need it in the classpath when running. explanation: I'd like to find out if this is possible in eclipse. This scenario happens often for me. I'll have a large project, that uses alot of 3rd party libraries. And of course those 3rd party jars have their own dependencies as well. So I have to include all dependencies in the classpath ("build path" in eclipse) for the application and its tests to compile and run (from within eclipse). But I don't want my code to use all of those jars, just the few direct dependencies I've decided upon myself. So if my code accidentally uses a dependency of a dependency, I want it to show up as a compilation error. Ideally, as class not found, but any error would do. I know I can manually configure the classpath when running outside of eclipse, and even within eclipse I can modify the classpath for a specific class I'm running (in the run configurations), but thats not manageable if you run alot of individual test cases, or have alot of main() classes.

• Custom QGraphicsItems not compiling and give object is is private error

  - by bahree

  Hi, I am trying to create a Custom QGraphicsItem button as shown by Fred here. The code which he posted can be found here. The problem is when I try and compile the code I get the following two errors: /usr/include/qt4/QtGui/qgraphicsitem.h ‘QGraphicsItem::QGraphicsItem(const QGraphicsItem&)’ is private /usr/include/qt4/QtCore/qobject.h ‘QObject::QObject(const QObject&)’ is private Here is the code snippet which essentially is the same as that in the sample above. The error is on the class deceleration. class MyButton : public QObject, public QGraphicsItem { Q_OBJECT Q_INTERFACES(QGraphicsItem) public: MyButton(QGraphicsItem *parent = 0); MyButton(const QString normal, const QString pressed = "", QGraphicsItem *parent = 0); .... } Interestingly the other sample as shown here works fine. The sample code for that can be found here. Any idea what is wrong? Thanks in advance.

• How 'terse' is too terse? -- Practical guidelines for expressing as much intent in as few characters

  - by Christopher Altman

  First, I love writing as little code as possible. I think, and please correct me, one of the golden rules of programming is to express your code in as few of character as possible while maintaining human readability. But I can get a little carried away. I can pack three or four lines into one statement, something like $startDate = $dateTime > time() ? mktime(0,0,0,date('m',time()-86400),date('d',time()*2),2011) : time(); (Note: this is a notional example) I can comprehend the above code when reading it. I prefer 'mushing' it all together because having less lines per page is a good thing to me. So my question: When writing code and thinking about how compact or terse you can express yourself, what are some guidelines you use? Do you write multiple lines because you think it helps other people? Do you write as little as possible, but use comments? Or do you always look for the way to write as little code as possible and enjoy the rewards of compact statements? (Just one slightly off topic comment: I love the Perl one-liners, but that is not what I am talking about here)

• Reuse, Rewrite, or Refactor?

  - by Jon Purdy

  At work I inherited development of a PHP-based Web site after the consultant who originally produced it bailed out and left without a trace. Literally half of the code is ripped from online tutorials, and there are thousands of lines of cruft that, being incomplete, do precious little. Hardly any of it actually works. I've been trying to pull out the usable components, such as the layout (cleverly intermixed with code), session management (delicately seasoned with unescaped, unvalidated SQL queries), and a few other things, but it's very difficult to force all of this junk into place. Further, I don't speak idiomatic PHP, being more of a Perl user, and I'm supposed to be on this project principally for maintenance, so rewriting everything seems like it would take just as long as wrestling the existing monster back into place. As an aside, I have literally never seen anything as badly written as this. Welcome me to the world of working with other people's code, I guess, but I do hope it's not this common in the real world to have such gems as these: // WHY IS THIS NOT WORKING // I know this is bad but were going for working stuff right now... // This is a PHP code outputing Javascript code outputting HTML...do not go further // Not userful I'm looking for the best advice I can get here. What would you do if you were in my position?

• jQuery; combine user click and :checked

  - by user275074

  I have two blocks of code which basically check for 1) a click event on a radio button e.g. $("input[id='frmSkill']").click(function(){ //do something }); And 2) a block of code to check if a radio button is :checked, if so, then perform some actions e.g. if($("input[id='frmSkill']:checked").val()){ //do something }); What I'd like to do is combine the two in order to reduce the code as the actions performed under each are the same.

• Why do software engineers hate writing documentation?

  - by Stewart Johnson

  I ask because I quite enjoy it! I'm talking about design documentation and implementation notes (NOT user manuals), which are non-existent in most of the codebases I've been handed. I can understand why a developer wouldn't want to write requirements (that's the analyst's job) or the user documentation (that's a technical writer's job) but I don't get why developers hate writing design docs. I don't think I would feel as if I'd finished the job if I only wrote the code and walked away -- mainly because when I've been introduced to code-only situations I've seen how hard it is to figure out what's been done and what the software does. I would hate for people to suffer the same situation when inheriting my code. What makes you loath writing supporting documentation for your code?

• Marshal a C++ class to C#

  - by Adam Haile

  I need to access code in a native C++ DLL in some C# code but am having issues figuring out the marshaling. I've done this before with code that was straight C, but seem to have found that it's not directly possible with C++ classes. Made even more complicated by the fact that many of the classes contain virtual or inline functions. I even tried passing the headers through the PInvoke Interop Assistant, but it would choke on just about everything and not really no what to do... I'm guessing because it's not really supported. So how, if at all possible, can you use a native C++ class DLL from .NET code. If I have to use some intermediary (CLR C++?) that's fine.

• int considered harmful?

  - by Chris Becke

  Working on code meant to be portable between Win32 and Win64 and Cocoa, I am really struggling to get to grips with what the @#$% the various standards committees involved over the past decades were thinking when they first came up with, and then perpetuated, the crime against humanity that is the C native typeset - char, short, int and long. On the one hand, as a old-school c++ programmer, there are few statements that were as elegant and/or as simple as for(int i=0; i<some_max; i++) but now, it seems that, in the general case, this code can never be correct. Oh sure, given a particular version of MSVC or GCC, with specific targets, the size of 'int' can be safely assumed. But, in the case of writing very generic c/c++ code that might one day be used on 16 bit hardware, or 128, or just be exposed to a particularly weirdly setup 32/64 bit compiler, how does use int in c++ code in a way that the resulting program would have predictable behavior in any and all possible c++ compilers that implemented c++ according to spec. To resolve these unpredictabilities, C99 and C++98 introduced size_t, uintptr_t, ptrdiff_t, int8_t, int16_t, int32_t, int16_t and so on. Which leaves me thinking that a raw int, anywhere in pure c++ code, should really be considered harmful, as there is some (completely c++xx conforming) compiler, thats going to produce an unexpected or incorrect result with it. (and probably be a attack vector as well)

• Eclipse does not format this if statement correctly

  - by Maroloccio

  This should be easy to answer: I have Eclipse set to wrap Java code over 80 chars to respect my margin. This code never wraps: if (expressionItem.type.isTypeCompatibleWith(containingNameLink.type) == false) { reportParsingError("expression type incompatible with containing " + "context."); } Question: how do I set my code formatter preferences so that the margin is respected?

• ASP NET MVC custom route fallback

  - by manudea

  I'm wondering if it is possibile to customize routing in a way that all requests are evaluated by a piece of code, redirected to the relevant controller if a match is found or passed to next rout in list if not found. sample request: /my coolpage/another one the code searches and determine that the right controller for this is Page, action is "list" and id is "123" and so redirects another request: /products/list/5 code finds no match al passes it back to next route that knows how to handle it... any idea on how to do this?

• Why is TransactionScope using a distributed transaction when I am only using LinqToSql and Ado.Net

  - by Ian Ringrose

  We are having problems on one machine, with the error message: "MSDTC on server XXX is unavailable." The code is using a TransactionScope to wrap some LingToSql database code; there is also some raw Ado.net inside of the transaction. As only a single sql database (2005) is being accessed, why is a distributed transaction being used at all? (I don’t wish to know how to enable MSDTC, as the code needs to work on the server with their current setup)

• How to safely use VSS when using a working directory on a thumb drive?

  - by MatthewMartin

  I know putting code into VSS in general is as safe as putting money into a mutual fund run by Bernard Madoff, but I don't have the luxury of ditching it for subversion. That said, I need to be able to write code on two machines, I'm considering checking out code to a flash thumb drive. Anyone know in advance what I should/shouldn't do to avoid loss of work? Do I need to ensure the drive letter stays the same?

• Custom roles in ASP.NET

  - by MainMa

  Hi, I am working on an ASP.NET website which uses forms authentication with a custom authentication mechanism (which sets e.Authenticated programmatically on protected void Login_Authenticate(object sender, AuthenticateEventArgs e)). I have an ASP.NET sitemap. Some elements must be displayed only to logged in users. Others must be displayed only to one, unique user (ie. administrator, identified by a user name which will never change). What I want to avoid: Set a custom role provider: too much code to write for a such basic thing, Transform the existing code, for example by removing sitemap and replacing it by a code-behind solution. What I want to do: A pure code-behind solution which will let me assign roles on authenticate event. Is it possible? How? If not, is there an easy-to-do workaround?

• How to initiate chatting between two clients and two clients only, using applets and servlets?

  - by mithun1538

  Hello everyone, I first need to apologize for my earlier questions. (You can check my profile for them)They seemed to ask more questions than give answers. Hence, I am laying down the actual question that started all them absurd questions. I am trying to design a chat applet. Till now, I have coded the applet, servlet and communication between the applet and the servlet. The code in the servlet side is such that I was able to establish chatting between clients using the applets, but the code was more like a broadcast all feature, i.e. all clients would be chatting with each other. That was my first objective when I started designing the chat applet. The second step is chatting between only two specific users, much like any other chat application we have. So this was my idea for it: I create an instance of the servlet that has the 'broadcast-all' code. I then pass the address of this instance to the respective clients. 2 client applets use the address to then chat. Technically the code is 'broadcast-all', but since only 2 clients are connected to it, it gives the chatting between two clients feature. Thus, groups of 2 clients have different instances of the same servlet, and each instance handles chatting between two clients at a max. However, as predicted, the idea didn't materialize! I tried to create an instance of the servlet but the only solution for that was using sessions on the servlet side, and I don't know how to use this session for later communications. I then tried to modify my broadcast-all code. In that code, I was using classes that implemented Observer and Observable interfaces. So the next idea that I got was: Create a new object of the Observable class(say class_1). This object be common to 2 clients. 2 clients that wish to chat will use same object of the class_1. 2 other clients will use a different object of class_1. But the problem here lies with the class that implements the Observer interface(say class_2). Since this has observers monitoring the same type of class, namely class_1, how do I establish an observer monitoring one object of class_1 and another observer monitoring another object of the same class class_1 (Because notifyObservers() would notify all the observers and I can't assign a particular observer to a particular object)? I first decided to ask individual problems, like how to create instances of servlets, using objects of observable and observer and so on in stackoverflow... but I got confused even more. Can anyone give me an idea how to establish chatting between two clients only?(I am using Http and not sockets or RMI). Regards, Mithun. P.S. Thanks to all who replied to my previous (absurd) queries. I should have stated the purpose earlier so that you guys could help me better.

• Can I use pdb files to step through a 3rd party assembly?

  - by Pure.Krome

  Hi folks, my friend has made a really helpful class library which I use all the time. I usually use Reflector to see what his code does. What I really wanted to do was to step through his code while I'm debugging. So he gave me his .pdb file. Foo.dll (release configuration, compile) Foo.pdb Now, I'm not sure how I can get it to auto break into his code when it throws an exception (his code, at various points, thorws exceptions .. like A first chance exception of type 'System.Web.HttpException' occurred in Foo.dll ... Can I do this? Do i need to setup something with the Symbol Server settings in Visual Studio ? Do i need to get the dll compiled into Debug Configuration and be passed the .dll and .pdb files? Or (and i'm really afraid of this one) .. do i need to have both the .dll, .pdb AND his source code ... I also had a look at this previous SO question, but it sorta didn't help (but proof I've tried to search before asking a question). Can someone help me please?

• Using a variable name in XMLHttpRequest

  - by Paul

  Hi All, I am using jQuery and trying to load a variable in place of a named xml file. My Code: $(document).ready(function() { // bind 'myForm' and provide a simple callback function $('#theForm').ajaxForm(function(responseXML2) { var myxml = responseXML2; alert(responseXML2); displayResult(); }); }); function loadXMLDoc(dname) { if (window.XMLHttpRequest) { alert("loading xmlhttprequest"); xhttp=new XMLHttpRequest(); } else { alert("loading activeX"); xhttp=new ActiveXObject("Microsoft.XMLHTTP"); } alert("bottom load"); xhttp.open("GET",dname,false); xhttp.send(); return xhttp.responseXML; } function displayResult() { alert("setting vars"); alert("displayResult called"); //xml=loadXMLDoc(responseXML2); //tried this and the line below, among others xml=responseXML2; alert("xmlDocLoaded"); xsl=loadXMLDoc("xslt-test.xsl"); alert("XSLloaded"); // code for IE if (window.ActiveXObject) { alert("IE"); ex=xml.transformNode(xsl); document.getElementById("ieiresponse").innerHTML=ex; } // code for Mozilla, Firefox, Opera, etc. else if (document.implementation && document.implementation.createDocument) { alert("notIE"); xsltProcessor=new XSLTProcessor(); xsltProcessor.importStylesheet(xsl); resultDocument = xsltProcessor.transformToFragment(xml,document); document.getElementById("ieiresponse").appendChild(resultDocument); } } In the code above I want to have: //xml=loadXMLDoc(responseXML2); //tried this and the line below, among others xml=responseXML2; instead of a named file: xsl=loadXMLDoc("example.xml"); When I run through the code, it works if I name the file, but when I use the variable, (which does show up in alerts, so is being pulled), it stops the code at the above line (placing the variable as the xml file) Any help would be much appreciated! Thank you in advance.

• google maps not working anymore at the drop of a hat

  - by Vordreller

  2 days ago, I was working on a project that involves google maps. The website showed the maps on the pages just fine. Now, I come back to my workstation, nothing has changed, expect for the fact that the google maps won't show up anymore. The code is identical, nobody has touched my machine since I was gone, I've checked the html, everything is perfect and still this isn't working... The Javascript console is giving no errors and the code is identical to a backup I make everytime I call it a day. 2 days ago it was working, today it isn't. I've even copied the source code, put it into an html file and tried that, but the same result. I'm at a loss here. This is my code: <script type="text/javascript"> //<![CDATA[ var map; var directionsPanel; var directions; function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); //the route description directionsPanel = document.getElementById("route"); directions = new GDirections(map, directionsPanel); directions.load({COMMAND}); } } //]]> </script> The {COMMAND} is something that the PHP template will parse, I've checked it, the format is 100% correct and like I allready said, code now is identical to the backup, and if it worked back then, it should work now. Did google update their API overnight and did a function that I use here become deprecated? I don't know what's going on here...

• ASP.NET cached aspx page & IIS logs

  - by Vishal Seth

  Hi guys, Is there any way to find out if ASP.Net runtime has served a cached copy of ASPX page or actually went through the page life cycle? Here is my problem: I'm seeing many entries in my IIS log files that were served successfully (200 OK). I've a corresponding logging code (Log4Net API) in the Session_Start and Application_BeginRequest() events that is logging every request to my DB with more details. I'm not seeing any corresponding entries in my SQL DB for some cases that should have been created by Log4Net code. Are there any logs available to find out if a cached copy was served by .NET worker process? Moreover, if my logging code would throw an exception, won't that show up as 500 in IIS logs? The code is on Windows 2008 Server, IIS 7.
