  • microsoft windows driver kit pure C try catch syntax ?

    - by clyfe
    In the Windows Driver Kit (WDK) there are some driver code samples written in pure C, but sprinkled with some try-catch-finally constructs. Does someone know their semantics ? Thank you microsoft for your great tools and standards compliance. Code extract from some_file.c: try { ... if (!NT_SUCCESS( status )) { leave; // ??? } ... } finally { ... } try { ... } except( EXCEPTION_EXECUTE_HANDLER ) { ... }

  • Adding an IList item to a particular index number

    - by Dr. Zim
    Our Client's database returns a set of prices in an array, but they sometimes don't include all prices, i.e., they have missing elements in their array. We return what we find as an IList, which works great when we retrieve content from the database. However, we are having difficulties setting the elements in the proper position in the array. Is it possible to create an IList then add an element at a particular position in the IList? var myList = new List<Model>(); var myModel = new Model(); myList[3] = myModel; // Something like what we would want to do

  • JavaScript setInterval loop not holding variable

    - by Ryan
    Here is my code: var showNo = 1; window.setInterval(function() { console.log(showNo); if(showNo === 1) { var nextNo = 2; } else if(showNo === 2) { var nextNo = 3; } else if(showNo === 3) { var nextNo = 4; } else if(showNo === 4) { var nextNo = 5; } else if(showNo === 5) { var nextNo = 1; } else { var showNo = 1; var nextNo = 2; } var showNo = nextNo; }, 500); My question is, why is the showNo variable not holding when the setInterval loop starts? The console displays 'undefined' in the above example. This may be a simple question, but I am trying to teach myself query and this has me stuck.. Any answers would be great. Thanks.

  • How do you use pip, virtual_env and Frabric to handle deployement?

    - by e-satis
    What are your settings, your tricks, and above all, your workflow. These tools are great but they is still no best practices attached to their usage, so I don't know what is the most efficient way. Do you use pip bundles or always download? Do you set up Apache/Cherokee/MySQl by hand or do you have a script for than. Do you put everything in virtual_env and use --no-site-package? Do you use one virtual_env for several projects? What do you use Fabric for (which part of your deployment do you script)? Do you put your Fabric scripts in on the client or the server? How do you handle database and media file migration? Do you even need a build tool such as SCons? What are the steps of your deployment? How often do you perform each of them? etc.

  • Get All Users in an Active Directory Group

    - by Matt Hanson
    I'm using the following code sample to get a list of all users in a specified AD group (in this case, all users in the "Domain Users" group). My listed code works great, with one exception: it won't return users who have their primary group set to "Domain Users". How can I get a list of all users in the group, including those who have it set as their primary group? Private Sub GetUsers() Dim groupSearcher As New DirectorySearcher Dim groupSearchRoot As New DirectoryEntry("LDAP://OU=Users,DC=domain,DC=com") With groupSearcher .SearchRoot = groupSearchRoot .Filter = "(&(ObjectClass=Group)(CN=Domain Users))" End With Dim members As Object members = groupSearcher.FindOne.GetDirectoryEntry.Invoke("Members", Nothing) For Each member As Object In CType(members, IEnumerable) Console.WriteLine(New DirectoryEntry(member).Name.Remove(0, 3)) Next End Sub

  • UI Components for Windows Mobile Applications (.NET Compact Framework)

    - by splattne
    Applications which run on mobile devices have special user interface requirements. I think Apple did a great job introducing innovative controls on the iPhone/iPod touch platform. Now, I have to design an application for the Windows Mobile platform using the .NET Compact Framework (Visual Studio 2008). I wonder if there are some commercial or open source UI control sets available which are similar to the iPhone / iPod touch UI elements: Scrolling panels based on gestures Instead of a dropdownlist: a new panel with a large list of items Sliding panels etc. I couldn't find any useful products/code. Maybe there is somebody out there with more experience who could help.

  • How do I get selected background color from SecondView to pass to FirstView?

    - by rob
    I am going insane! This is a simple app with two Views. FirstView is a text field with info button to flip to SecondView. In SecondView I have 6 buttons for background color choice. When button is pushed the color of background changes perfectly but cannot make it also change background color for FirstView. Any help would be GREAT! Thanks! I am using Objective C class working on a iPhone app. Sorry new at this. The SecondView acts almost like a settings page in the fact that when a button is pushed the background color changes to the button color. I need it so when I push the "back" button to go back to FirstView the background color has also changed to that color choice. Been thru sooooooooo many tutorials and codes that now I am totally lost......... Thanks again!

  • Does the WCF framework support the XSD IDREF restriction?

    - by Gerard
    A nice feature in XSD is the IDREF restriction, e.g.: <xs:restriction base="xs:IDREF"> <xs:pattern value="[0-9a-zA-Z\-]+"/> </xs:restriction> I used this restriction with great benefit in a Java JAXWS-project. An object serialized in a SOAP XML datamodel can hold a reference (pointer) to another object in the same SOAP message. I want to try the same approach in a C# WCF-project, can it be done? On the web site Data Contract Schema Reference I can see e.g. Id ignored, Ref forbidden, but I am not sure whether I understand what that means.

  • Help with Event-Based Components

    - by Joel in Gö
    I have started to look at Event-Based Components (EBCs), a programming method currently being explored by Ralf Wesphal in Germany, in particular. This is a really interesting and promising way to architect a software solution, and gets close to the age-old idea of being able to stick software components together like Lego :) A good starting point is the Channel 9 video here, and there is a fair bit of discussion in German at the Google Group on EBCs. I am however looking for more concrete examples - while the ideas look great, I am finding it hard to translate them into real code for anything more than a trivial project. Does anyone know of any good code examples (in C# preferably), or any more good sites where EBCs are discussed?

  • Checkstyle for C#?

    - by PSU_Kardi
    I'm looking to find something along the lines of Checkstyle for Visual Studio. I've recently started a new gig doing .NET work and realized that coding standards here are a bit lacking. While I'm still a young guy and far from the most experienced developer I'm trying to lead by example and get things going in the right direction. I loved the ability to use Checkstyle with Eclipse and examine code before reviews so I'd like to do the same thing with Visual Studio. Anyone have any good suggestions? Another thing I'd be somewhat interested in is a plug-in for SVN that disallows check-in until the main coding standards are met. I do not want people checking in busted code that's going to wind up in a code review. Any suggestions at this point would be great.

  • Convert Hexadecimal String to Data

    - by AriX
    Hi Stack Overflow, I have found a whole lot of different solutions to this problem, but not all of them work, and a lot of them seem somewhat hacky and inefficient. Basically I have a string of hexadecimal data (i.e. "55 AA 41 2A 00 94 55 AA BB BB 00 FF") which I would like to convert to raw data. What is the best way to do this? UPDATE: Vicky's solution worked great for me, but I changed it to work with hexadecimal strings that don't have spaces in between and changed the style a bit. int i = 0; char *hexString = "55AA412A009455AABBBB00FF" char *hexPtr = hexString; unsigned int *result = calloc(strlen(hexString)/2 + 1, sizeof *result); while (sscanf(hexPtr, "%02x", &result[i++])) { hexPtr += 2; if (hexPtr >= hexString + strlen(hexString)) break; } return result;

  • Code completion in NetBeans' python plugin does not work properly

    - by T.K.
    I am asking on StackOverflow because surely I am doing something completely silly and I hope S.O. might provide me with a quick answer. I've installed the latest stable Python-plugin for NetBeans. It works great, and I tested code completion with various packages such as sys, os and so on. It works beautifully. However, it does not seem to pick up the code completion for the code in my own project. I created a package called mypackage (it has _init_.py as well), and in it I have a module called mymodule.py. Inside mymodule I've put a class called MyClass, complete with doc-strings and all. Please refer to this screenshot to describe what happens in code-completion: As you see, it's suggesting irrelevant things, as opposed to just MyClass. (Note that if I execute mymodule.MyClass() it works 100%, it's just that I would really like code completion on my own code) Hope I'm just doing something silly here... Any ideas?

  • Error in writting a class.

    - by Richard
    I am running through a tutorial online at http://www.sthurlow.com/python/lesson08/ and I believe I understand how classes work in python, at least to some degree but when I run this code: class Shape: def init(self,x,y): self.x = x self.y = y description = "This shape has not been described yet" author = "Nobody has claimed to make this shape yet" def area(self): return self.x * self.y def perimeter(self): return 2 * self.x + 2 * self.y def describe(self,text): self.description = text def authorName(self,text): self.author = text def scaleSize(self,scale): self.x = self.x * scale self.y = self.y * scale I get this error: Traceback (most recent call last): File "Y:/python/Shape.py", line 1, in -toplevel- class Shape: File "Y:/python/Shape.py", line 17, in Shape self.y = self.y * scale NameError: name 'self' is not defined Any Help would be great Thanks Richard

  • How to parse a text file and write the result to an xls file?

    - by Bk
    Hi all i am a junior level SQL developer. I have a situation where I have a text file with 1100 lines of a search result with each line containing a file path and a stored procedure associated with that file. Each line has a structure like the one below: abc\def\ghi\***.cs(40): jkl=******.*****.******, "proc_pqrst", parms); Where abc\def\ghi\***.cs is file path of the file ***.cs. The stored procedure names begin with proc_. I have to extract the ***.cs and the corresponding stored procedure name begining with proc_ and write them to a .xls file. Can some body help me in writing the parsing program to do this? Also can I get a detailed outline on where should I write the code for c# and where should I compile it? This could be a great help as I don't have any knowledge of C#. Thank you, BK.

  • Why this doesn't work: [MySQL][ODBC 5.1 Driver]Access denied for user

    - by bvandrunen
    So I know that there is a very similar question to this all over the web as well as stack overflow: http://stackoverflow.com/questions/2539961/error-access-denied-for-user-mysql-server but my question I think is different. So I have set up a linked server and it works...I have the correct permissions set up for my IP's that I am using. However the problem arises when our user "webuser@correctIP" tries to access it. Therefore, any user using window authentication is allowed to access it and works great...but any that are not using windows authentication are blocked. However, I have tried all the common solutions such as setting up a strict password, changing security settings in Microsoft SQL Server etc. Nothing is working. Any help is appreciated. Thanks. FYI: I am using this from Microsoft SQL Server 2008 - mysql (through myphpadmin)

  • Anyone up to creating a tomcat based alternative for GAE?

    - by bach
    Hi, If we had the possibility to run GAE app without any code change on our servlet engine that would be great because: in case that google changes their billing policy we can just jump to our own server or in case their current policy doesn't fit our app needs we can do stuff which is not allowed in the GAE, compromising a 1 JVM, 1 DB We don't actually need a distributed system but more of a realtime system with synchronize, true locking mechanisms, other servers/software installed on the server machine, socket interface etc... Such a package should include at least: TomCat (or equivalent) DataNucleus Access Platform (Task Queue service) Any idea if it's easy to get such a thing or if it's already exist somewhere? Thanks

  • Computationally intensive scala process using actors hangs uncooperatively

    - by Chick Markley
    I have a computationally intensive scala application that hangs. By hangs I means it is sitting in the process stack using 1% CPU but does not respond to kill -QUIT nor can it be attached via jdb attach. Runs 2-12 hours at 800-900% CPU before it gets stuck The application is using ~10 scala.actors. Until now I have had great success with kill -QUIT but I am bit stumped as to how to proceed. The actors write a fair amount to stdout using println which is redirected to a text file but has not been helpful so far diagnostically. I am just hoping there is some obvious technique when kill -QUIT fails that I am ignorant of. Or just confirmation that having multiple actors println asynchronously is a real bad idea (though I've been doing it for a long time only recently with these results) Details scala 2.8.1 & 2.8.0 mac osx 10.6.5 java version "1.6.0_22" Thanks

  • .NET Assembly Diff / Compare Tool - What's available?

    - by STW
    I'd like to be able to do a code-level diff between two assemblies; the Diff plug-in for Reflector is the closest thing I've found so far, but to compare the entire assembly is a manual process requiring me to drill-down into every namespace/class/method. The other tools I've found so far appear to be limited to API-level (namespaces, classes, methods) differences--which won't cut it for what I'm looking for. Does anyone know of such a tool? My requirements (from highest to lowest) are: Be able to analyze / reflect the code content of two versions of the same assembly and report the differences Accept a folder or group of assemblies as input; quickly compare them (similar to WinMerge's folder diff's) Quick ability to determine if two assemblies are equivalent at the code level (not just the API's) Allow easy drill-down to view the differences Exporting of reports regarding the differences (Personally I like WinMerge for text diffs, so an application with a similar interface would be great)

  • Implementing OFX specification with javascript

    - by John Langston
    Hey all, I am working on a personal project and need to retrieve financial data. After looking around how this is normally done it seems you can pay lots of money and license a service like Yodlee to get this data for you or you can implement a OFX client like wesabe has to communicate with financial institutions. Seeing as I don't have lots of money and wouldn't mind the challenge I decided to try to implement the ofx spec (unless one of you can suggest a cheap/free alternative!). I looked around for some ofx libraries other people have already written for use but didn't find anything that looked too great. I was wondering if anyone knew if it would be a bad idea to attempt this in Javascript (using XMLSocket from actionscript to handle the actual socket communication). If there is some really bad reason why I shouldn't do this please bring it up. If there is I'll just do it in Java but I think it would be neat to have it completely in javascript so it runs client-side. Anyways I was hoping for some helpful input, thanks.

  • Searching with Linq

    - by Phil
    I have a collection of objects, each with an int Frame property. Given an int, I want to find the object in the collection that has the closest Frame. Here is what I'm doing so far: public static void Search(int frameNumber) { var differences = (from rec in _records select new { FrameDiff = Math.Abs(rec.Frame - frameNumber), Record = rec }).OrderBy(x => x.FrameDiff); var closestRecord = differences.FirstOrDefault().Record; //continue work... } This is great and everything, except there are 200,000 items in my collection and I call this method very frequently. Is there a relatively easy, more efficient way to do this?

  • Python Profiling in Eclipse

    - by Jordan L. Walbesser
    This questions is semi-based of this one here: http://stackoverflow.com/questions/582336/how-can-you-profile-a-python-script I thought that this would be a great idea to run on some of my programs. Although profiling from a batch file as explained in the aforementioned answer is possible, I think it would be even better to have this option in Eclipse. At the same time, making my entire program a function and profiling it would mean I have to alter the source code? How can I configure eclipse such that I have the ability to run the profile command on my existing programs? Any tips or suggestions are welcomed!

  • Why does the release build of my iPhone app crash on the device on the first run after installation?

    - by Chris Cooper
    I have an iPhone app that's been in development for about 2 weeks. We recently tried the "release" version of the build on a device, and to our great unhappiness, it crashes in one of the views with an "EXC_BAD_ACCESS". This crash only occurs on devices, and only in the "release" build. Not only that, but it only happens the first time the app is launched! It is also 100% reproducible. We have removed the small block of code that deals with data persistence, and have tried re-openning Xcode, cleaning the project, deleting and reinstalling the app, etc., as some other questions suggest. Do you have any advice for a) what might be causing this problem, and b) how to go about debugging if it only happens in "release"? Thanks

  • Handling log-in / log-out via Objective-c

    - by squeezemylime
    Having a real problem with this one...Tried using cookies to store variables, etc. but no luck. Writing an iPhone app where the User has to log in. There is an HTTPS call to get the person's userid, which is used practically everywhere else in the app, so that either has to be stored in a global variable or a cookie (for sending messages to other users, etc.) I tried the cookie route, but am having great difficulty storing (and retriving) a user ID in a cookie. The User should be able to then close out of the app and then reboot it and have the app retain their User ID as well, so I'm not sure global variables are necessarily the solution to this. Are there any best practices or suggestions?
