  • VB.NET generates properties in the release build

    - by dattebayo
    I have a form and i drag and drop a control in VB.NET. I have a line say, private WithEvents radioButton RadioButton Also, I have a handler like, private void click(.....) Handles radioButton.Click { ... } Now, When I build this is .NET 3.5 in release mode, and see the generated code in reflector tool, the code is something like, Private Overridable Property radioButton As RadioButton . . . <AccessedThroughProperty("radioButton")> _ Private _radioButton As RadioButton Can someone tell me what is going on here? And how do I avoid the generation of new properties and fields? -datte

  • Software for defining rules for folder permissions and monitoring deviations

    - by Kjensen
    Let's say a company has a large number of users, and each user has a home area. On each share used for home area folders, I would like to define some rules saying who is supposed to have which permissions on the folder. Then I would like to audit automatically, that this is actually the case and get some sort of report on deviations. So a rule for \MegaServer\Home01 could be defined something like: Domain Admins - Full Control Backup Agent - Read [Home folder owner] - Full Control I am talking about Windows platform and Windows servers, although I think it would most likely also work for *nix machines that expose Windows shares. Does software like this exist? I could roll my own basic version, but if something already exists, that is usually a better option. I am aware of tools to make displaying permissions easier (AccessEnum, DumpSec), but that is not what I am looking for.

  • "Punch card" application

    - by icelava
    Our main-con manager is looking for a "punch card" type of attendance-logging application. We need to take attendance every day, and the most "automatic" method is simply to track when people unlock their Windows desktop screen (not logon, because many simply leave the computer on indefinitely), and report to a remote location/repository, where the administrator will be able to observe which users unlocked their screens each day. Has anybody come across such an application suite? It likely has to be a Windows service so that it operates regardless of who is logged into the system.

  • Full GC real time is much more that user+sys times

    - by Stas
    Hi. We have a Web Java based application running on JBoss with allowed maximum heap size of about 1.2 GB (total machine physical memory is 2 GB). At some point the application stops responding (to clients) for several minutes. After some analysis we found out that the culprit is the Full GC. Here's an excerpt from the verbose GC log: 74477.402: [Full GC [PSYoungGen: 3648K-0K(332160K)] [PSOldGen: 778476K-589497K(819200K)] 782124K-589497K(1151360K) [PSPermGen: 102671K-102671K(171328K)], 646.1546860 secs] [Times: user=3.84 sys=3.72, real=646.17 secs] What I don't understand is how is it possible that the real time spent on Full GC is about 11 minutes (646 seconds), while user+sys times are just 7.5 seconds. 7.5 seconds sound to me much more logical time to spend for cleaning <200 MB from the old generation. Where does all the other time go? Thanks a lot.

  • How to add recently set cookies to nginx's access log

    - by etoleb
    I'd like to include cookie data in an nginx access log like so: (simplified example) log_format foo '$remote_addr "$request" $cookie_bar'; access_log /var/log/nginx/access.log foo; This works great on requests that already have a cookie "bar", but for the first request to my server nginx will report "-" as the value of "bar". It seems like my problem is that nginx is looking at the request headers for the cookie value. Is there a way check for a Set-Cookie in the response and use that as a fallback?

  • Should GSON ignore varying types if they're not used in a class?

    - by loeschg
    I'm making an API call that returns JSON which has a particular field which either returns false or a map depending on content. It's a field that I don't care about. I expected GSON to ignore this particular field, though it doesn't seem to be. The object generation fails with the following message: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 403560 I've seen this particular question (Gson deserialize json with varying value types). I want to make sure I need to make a custom deserializer before doing so. I'm wondering if I may have another issue. edit: Example: "anonymous_flag": { } vs "anonymous_flag": "yes" Another Edit: I actually had the field in my model object... I was referencing the wrong class. Judge away :)

  • How to change the computer name on a server configured by Puppet

    - by David Sulpy
    I am new to Puppet and I'm trying to get Puppet to configure my EC2 instances after they're started from a Cloud Formation Template in AWS. The problem is that all the nodes that get started from the Cloud Formation Template all have the same name (the name from the AMI that the new nodes derive from). I would love to find a way to have puppet rename the nodes when the nodes start up. (although, as far as I know, a Computer Name change requires reboot, a separate issue...) If you can point me to some documentation that can help me figure this out or if you have any ideas that would be great. My ultimate goal is to have each EC2 start with a unique name so that I can use New Relic server monitoring to report the different servers.

  • How to color a mesh with values at the vertices in WPF 3D?

    - by Christo
    We've got a sphere which we want to display in 3D and color given a fuction that depends on spherical coordinates. The sphere was triangulated using a regular grid in (theta, phi), but this produced a lot of small triangles near the poles. In an attempt to reduce the number triangles at the poles, we've changed out mesh generation to produce more evenly sized triangles over the surface. The first triangulation method had the advantage that we could easily create a texture and drape it over the surface. It seems that in WPF it isn't possible to assign colors to vertices the way one would go about in OpenGL or Direct3D. With the second triangulation method it isn't apparent how to go about generating the texture and setting the texture coordinates, since the vertices aren't aligned to a grid anymore. Maybe it would be possible to create a linear texture containing a color for each vertex, but then how will that effect the coloring? Will it still render smoothly over the triangle surfaces as one would expect by applying per vertex coloring?

  • Qt: any way to automatically generate QSharedData-based structures?

    - by Eye of Hell
    Hello. Qt has a build-in supprt for creating objects with integrated reference counting via QSharedData and QSharedDataPointer. All wordks great, but for each such object i need to write a lot of code: QSharedData-based implementation class with constructor and copy constructor, object class itsef with accessor methods for each filed. For a simple structures with 5-10 fields this requires really lot of near same code. Is it some ways to automate such classes generation? Maybe it's some generators exists that take a short description and automatically generates implementation class and object class with all accessors?

  • Program is not displaying output correctly

    - by Dave Lee
    My program is suppose to display information from a text file. The text file is here http://pastebin.com/qB6nX2x4 I cant find the problem in my program.

  • Forcing a method to be non-transactional in JPA (Eclipselink)

    - by rhinds
    Hi, I am developing an application using Eclipselink and as part of the app I need to be able to manipulate some of the objects which involves changing data without it being persisted to the database (i merging/changing objects for some batch generation processes). I am reluctant to change the data in the Entity objects, as there is a risk that even though i have not marked the methods as @Transactional, this method could in the future be inadvertantly called from within a transactional method and these changes could be persisted. So my question is, is there anyway to get around this? Such as force a method to always be non-transactional regardless; terminate any transactionality as soon as the method is started; etc. I know there is a .detach() method that can detach the objects from the Entity Manager, however, there are many objects and this seems like a potentially error prone fail-safe on my code.

I generation is simple, base FlowLayoutPanel have other FlowLayoutPanels, for each have a Label and TextBox with DataBinding. Problem is this is VERY SLOW, up to 20 seconds, i drawing less than 100 controls, from Performace Session i know a problem is on 70% procesing functions: System.Windows.Forms.Control.ControlCollection.Add(class System.Windows.Forms.Control) System.Windows.Forms.ControlBindingsCollection.Add(class System.Windows.Forms.Binding) How i can do with this? Anyone help me in this problem? How solve the dynamic form layout problem?

  • T4 Template Interception

    - by JeffN825
    I'm wondering if anyone out there knows of any T4 template based method interception systems? We are beginning to write mobile applications (currently with MonoTouch for IOS). We have a very nice core set of DI/IoC functionality and I'd like to leverage this in development for the new platform. Since runtime code generation Reflection.Emit is not supported, I'm hoping to use T4 templates to implement the dynamic interception functionality (+ TinyIoC as a container for resolution). We are currently using Castle Windsor (and intend to continue doing so for our SL and full .NET development), but all of the Windsor specific ties are completely encapsulated, so given a suitable T4 solution, it shouldn't be hard to implement an adapter that uses a T4 based implementation instead of Windsor.

  • Java: How can I create good looking class docs with Javadoc?

    - by Cheeso
    I'd like to create HTNML documentation for a Java class library that includes programming guide information - beyond just a class reference code examples in the reference doc collapsible regions I want it to look well-styled. Something like this: I think that Javadoc exposes a doclet API that allows other parties to provide doc generation integrated in Javadoc. Is there a doclet option that I can use (for free) that does something a little nicer than the standard javadoc output? I tried googling for this but no luck. Suggestions?

  • HP DL380 G5 Predictive failure of a new drive

    - by CharlieJ
    Consolidated Error Report: Controller: Smart Array P400 in slot 3 Device: Physical Drive 1I:1:1 Message: Predictive failure. We have an HP DL380 G5 server with two 72GB 15k SAS drives configured in RAID1. A couple weeks ago, the server reported a drive failure on Drive 1. We replaced the drive with a brand new HDD -- same spares number. A few days ago, the server started reporting a predictive drive failure on the new drive, in the same bay. Is it likely the new drive is bad... or more likely we have a bay failure problem? This is a production server, so any advice would be appreciated. I have another spare drive, so I can hot swap it if this is a fluke and new drive is just bad. THANKS! CharlieJ

  • Dynamic, reflective SignalHandler in Java

    - by pilcrow
    How do I install signal handling logic iff sun.misc.Signal is available? Background First generation of my code looked something like this: class MyApp { public static void main(String[] args) { ... Signal.handle(term_sig, new SignalHandler() { public void handle(Signal sig) { ... } }); ... } } I believe I understand how to reflectively test for and use signal handlers -- Class.forName("sun.misc.Signal"), reflectively call Signal.handle, and so forth. My impulse was simply to instantiate another anonymous inner class with the dynamically obtained SignalHandler class, but I think that's just wishful syntax.

  • Should I use WPF or Windows Forms Application for my project in C#?

    - by RAJ K
    I am developing a Client-Server based application in which client application will access server database to store billing information. It will also have report generation facility. Windows Forms is good in document printing & I don't see such facility or controls in WPF. If I am wrong then please correct me. I want database security, which DB should I use, SQL Server, MySQL or Oracle. I would like to use free DB but security is my priority. Please suggest how I can implement a Client-Server architecture with multiple clients in C#? Thank you Geeks!!!

  • Making Django ignore string literals

    - by James
    UPDATE: It turns out this is a deeper question than I thought at first glance - the issue is that python is replacing the string literals before they ever get to django. I will do more investigating and update this if I find a solution. I'm using django to work with LaTeX templates for report generation, and am running into a lot of problems with the way Django replaces parts of strings. Specficially, I've run into two problems where I try to insert a variable containing latex code. The first was that it would replace HTML characters, such as the less than symbol, with their HTML codes, which are of course gibberish to a LaTeX interpreter. I fixed this by setting the context to never autoescape, like so: c = Context(inputs) c.autoescape = False However, I still have my second issue, which is that Django replaces string literals with their corresponding characers, so a double backslash becomes \, and \b becomes a backspace. How can I force Django to leave these characters in place, so inputs['variable'] = '{\bf this is code} \\' won't get mangled when I use {{variable}} to reference it in the django template?

  • How to manage SOAP requests to a pool of VM each listening on a HTTP port with a priority value in these requests?

    - by sputnick
    I have a front SOAP web-server under Linux. It will have to communicate with Windows Servers VM listening each on a HTTP port, for a HTTP POST request. The chosen VM should return a report of the task to the SOAP client. In the SOAP requests, there's a special variable : the priority of the request (kind of SLA), and my question is coming right now : I think of using a ha software (nginx, HAProxy, HeartBeat...) that can manage priority in this point of view. Is it relevant or do you think I need to implement a queue by myself with some specific developments? Ex: I have a SOAP requests with low priority in the pipe : the weight priority for these VM should be decreased if I have high priority SOAP requests at the same time. Any clue will be really appreciated.

  • Netbeans hard freezes Windows XP, how to debug

    - by Jestep
    I get this problem about once to twice a day while editing in netbeans. I will be editing some code in Netbeans and I get a hard freeze requiring a full reboot. There hasn't been any correlation with an actual event that I can tell. Sometimes it's when I focus, sometimes while typing, sometimes while clicking on another window. I need to figure out how to track down what's causing the problem, as no error is generated when this happens. No error in Netbeans logs or Windows logs. I've also tried letting it sit to see if it recovers, and it's definitely stuck. I haven't had any problems with other apps running JRE, so I'm thinking it's Netbeans itself. I can't submit a bug report because I can't get a log or any reproduce-able explanation of the problem.

  • Video driver reports 8-bit color depth after Windows Update

    - by user3163
    Windows Update pushed out a new video driver for the Mobile Intel(R) 4 Series Express Chipset Family. One HP 6730b laptop was updated from 8.15.10.1872 to 8.15.10.2021. After the update the color depth is reported as 8-bit even if the setting is 32-bit. This means that Areo effects are disabled. Downgrading to 8.15.10.1872 did not help. Is there any way to force the video driver to report 32-bit color depth?

  • How to update SQL Server database from multiple data sources for ASP.Net MVC 4 application

    - by shaz
    I have 10+ SQL Server databases, from where I would use one table from each database to display information using the application that I am creating. For instance, DB1, DB2....DB10. NewDB (Account, Country, Costcenter....etc.). I have started with creating a new database which would contain all the information from all those 10+ databases. However, I am confused in many cases. First of all what process should I follow? Shall I create a table (in new database) with the same structure as the actual data source and insert data from actual data source to new database? Should I be doing this on the DBMS? If so, is it some scripting? (hint expected since very new to this) I am creating a report generation application which has 10+ data sources. I need some hint which way should I proceed? Thanks for advice/help in advance.

  • Typed DataSet connection - required to have one in the .xsd file?

    - by Kyralessa
    In the .xsd file for a typed DataSet in .NET, there's a <Connections> section that contains a list of any data connections I've used to set up the DataTables and TableAdapters. There are times when I'd prefer not to have those there. For instance, sometimes I prefer to pass in a connection string to a custom constructor and use that rather than look for one in settings, .config, etc. But it seems like if I remove the connection strings from that section (leaving it empty), or remove the section entirely, the DataSet code-generation tool freaks out. Whereas if I don't remove them, the DataSet gripes when I put it in a different project because it can't find the settings for those connection strings. Is there any way I can tell a typed DataSet not to worry about any connections? (Obviously I'll have to give it a connection if I change any TableAdapter SQL or stored procs, but that should be my problem.)
