• Stagger increments in C# NumericUpDown control

  - by mihe

  Hi cloud of wisdom :-) I am facing some trouble trying to configure a particular configuration for a NumericUpDown control in c#. Basically, I have seen that I can set the Increment interval, but I would like to manage the Increment interval depending on which arrow is clicked (up or down). I have checked the events of the control, but I do not find an event for each arrow. Basically, I want to achieve a control where, at different values, the increment is different. from 0.00 to 5.00 increments of 0.01, from 5.00 to 20.00 increments of 0.04, and so on Is this possible ? Note: It would be useful also an historic value in the control for the last value when the valuechanged event is trigger. Does this exist? Thanks in advance for any comment or suggestion!!!

• jQuery - Animation flicker using hover()

  - by Chris

  I have a setup as described in this question which works perfectly. Essentially a drop down menu grows when you move your mouse over it to expose more options. There is, however, a small issue. If you move the mouse outside of the #dropdown div and then back in again quickly it constantly fires the mouseenter and mouseleave events causing a never ending cycle of flickering. How can I get around it? Here is my current jQuery code $("#dropdown").hover(function() { $(this).stop(true,true).fadeTo('fast',1); $("#options").stop(true,true).slideDown(); }, function() { $(this).stop(true,true).fadeTo('fast',0.1); $("#options").stop(true,true).slideUp(); } );

• How much time do you spend in Reflector? (.NET)

  - by mannu

  As a consultant I get to toy around with many different products and APIs as the customer demands we use X and Y. I think it is great fun and I learn a lot from it. What will make a great developer over time is, in my opinion, the will to understand and learn new things. Therefore, I will always try to understand what happens "behind the scenes" when I am using 3rd party products. I spend around 10-15% of my time in Reflector to learn what the heck I'm really doing when I call method X. How much time do you spend on average? This may also apply to reading (open) source code, documentation etc.

• What to read as a good quick review and intro into development process methodologies?

  - by Ivan

  Being mostly self-taught freestyle developer and having no experience of working in teams of professionals in serious software companies, having only a very general idea of how the software development is should really be done, I think I've came to a point, when I begin struggling from lack of order in my work. I think I should get acquainted with professional software development technologies to optimize my own productivity and to extend my choice of work by increasing capabilities to work in teams and bigger companies. What should I begin with? Of course I am googling on this subject right now, but maybe hou have some real experience based recommendations to share?

• Stopping function on event in vb.net

  - by afilatun

  I have a vb.net application which does some processing. This processing can take a while. The application doesn't respond until the processing has ended and then it handle all events (such as click on buttons) that the user has done during the processing. I'd like to add a "Stop" button so that the user can stop the processing at some point. How can I do that? Could threading the processing (which is done in a function of the application) be a possible solution? I tried to add a button which change a boolean value and putting the code of the processing function inside a while statement based on that boolean value. However it doesn't work because the click event on the button is processed only after the end of the processing.

• FileSystemWatcher surpassing Active Directory restrictions

  - by DevexPP

  While experimenting with FileSystemWatcher, I've found out that it somehow surpasses Active Directory's restrictions to files and folders, and will raise change events with information about what has changed in files and folders that you don't even have access to. I have two questions about that: 1) Why does this happen ? 2) Is this a problem in the AD configuration ? how do I fix it ? 3) Is there any way to gather these files, or even create a FileSystemInfo of them to get more info about the files (not only the changes made on them) ? As far as I've tried, only the FileSystemWatcher immune to the restrictions, I can't run any other thing over it, here's a list of what I've tried: File.Exists Directory.Exists FileInfo instance on found files DirectoryInfo instance on found files File.Copy File.Delete

• How to Detect Trusted Connection in Crystal Reports using VB.NET?

  - by Michael

  I have some Crystal Reports connecting to a Sql Server db that I would like to detect whether the connection is trusted or whether I need to supply the log on info (reports are not supplied by me so I can't control the connect method). If I just blindly supply login credentials, it won't connect if it is a trusted connection. The following does not work: oRpt = oCR.OpenReport("C:\MyReport.rpt") if oRpt.Database.Tables(1).ConnectionProperties.Item("Integrated Security") = True then 'trusted connection else 'supply login credentials end if It gives the following error: Operator '=' is not defined for type 'IConnectionProperty' and type 'Boolean'. I cannot find how create a construct in vb.net for IConnectionProperty. I can't find any documents from Crystal that explain it. I am using Crystal Reports XI - Developer

• What is the best practice for accessing Model using MVVM pattern

  - by Dzenand

  I have a database that communicates with webservices with my Model (own thread) and exposes Data Objects. My UI application consists of different Views and ViewModels and Custom Controls. I'm using ServiceProvider (IServiceProvider) to access the Model and route the events to the UI thread. Communication between the ViewModels is handeled by a Messenger. Is this way to go? I was also wondering what is the best way to strucutre the DataObjects At the moment i have the DataObjects that have a hierarchy structure but does not support INotifyProperty though the children list are of type of ObservableCollection. I have no possiblity to implement notifypropertychange on the properties. I was wondering the best way of making them MVVM friendly. Implementing a partial class and adding all the properties or commands that are necessary or wrapping all the DataObjects and keep the Model list and MVVM list in sync. All thoughts and ideas are appreciated.

• Is there a limit to the number of DataContracts that can be used by a WCF Service?

  - by Chris

  Using WCF3.5SP1, VS2008. Building a WCF service that exposes about 10 service methods. We have defined about 40 [DataContract] types that are used by the service. We now experience that adding an additional [DataContract] type to the project (in the same namespace as the other existing types) does not get properly exposed. The new type is not in the XSD schemas generated with the WSDL. We have gone so far as to copy and rename an existing (and working) type, but it too is not present in the generated WSDL/XSD. We've tried this on two different developer machines, same problem. Is there a limit to the number of types that can exposed as [DataContract] for a Service? per Namespace?

• "No XML content. Please add a root view or layout to your document."

  - by ez4nick

  I am trying to follow this tutorial : http://developer.android.com/training/basics/firstapp/building-ui.html as I am new to android developing and this is what my "activity_main.xml" file looks like : <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal"> <EditText android:id="@+id/edit_message" android:layout_weight="1" android:layout_width="0dp" android:layout_height="wrap_content" android:hint="@string/edit_message" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/button_send" /> When I click run I get an error that says "No XML content. Please add a root view or layout to your document." and I noticed there is a new file generated called "activity_main.out.xml". What could I be doing wrong?

• How would you create a notification system like on SO or Facebook in RoR?

  - by Justin Meltzer

  I'm thinking that notifications would be it's own resource and have a has_many, through relationship with the user model with a join table representing the associations. A user having many notifications is obvious, and then a notification would have many users because there would be a number of standardized notifications (a commenting notification, a following notification etc.) that would be associated with many users. Beyond this setup, I'm unsure how to trigger the creation of notifications based on certain events in your application. I'm also a little unsure of how I'd need to set up routing - would it be it's own separate resource or nested in the user resource? I'd find it very helpful if someone could expand on this. Lastly, ajax polling would likely improve such a feature. There's probably some things I'm missing, so please fill this out so that it is a good general resource.

• How to stop C# compile on first error in VS 2010 (VS 2008 macros don't work)!

  - by Ben Robbins

  At work we have a C# solution with over 80 projects. Is it possible in VS 2010 to automatically stop compilation as soon as an error is encountered rather than the default behaviour which is to continue as far as possible and display a list of errors in the error window? I'm happy for it to stop either as soon as an error is encountered (file-level) or as soon as a project fails to build (project-level). I'd also note that in VS 2008 we used macros similar to some of the answers below but they don't work in VS 2010 (at least I couldn't get them to as the environment events don't seem to fire in VS 2010).

• WPF EDitable ComboBox

  - by Amittai Shapira

  Hi! I want to create editable combo box with the following properties: 1. Bind the text property to my data model. 2. The data model may override the changes in the GUI, even in Selection changed. E.g. I can choose from 1, 2, 3 I choose 2, but some component down under changes it to 3. 3. Update the data model on the following events: 1. Selection Changed 2. Lose focus 3. Enter pressed (should behave the same as lost focus). I've been able to create such control, but it's pretty ugly (using many hacks) and I hoped there's a simpler way… Thanks in advance

• Web Service returning object with null fields

  - by Xaiter

  Never seen this one before. WebService.Implementation imp = new WebService.Implementation(); WebService.ImplementationRequest req = new WebService.ImplementationRequest(); return imp.GetValue(req); The object that imp returns is not null. It's returning an ImplementationResponse, as expected. But all of the fields in that object are null. Which is not expected. The WebService, currently, just returns some constant dummy data. We've tested this on another developer's machine, works just fine. I suppose I should also note that the WebService should throw an exception if I pass null into the GetValue method. It doesn't. Not for me. Any idea what could be wrong with my environment that could make a WebService return an object, but make every value in that object null? And somehow 'magically' return this mystery object when it should be throwing an exception?

• FileSystemWatcher event trigger problem(s)

  - by Bahadir Cambel

  It seems like , FileSystemWatcher triggers events more than once. Here is my settings ; watcher = new FileSystemWatcher(); watcher.Path = @"D:\testSpace"; watcher.InternalBufferSize = 1024*64; watcher.Deleted += Triggered; watcher.Changed += Triggered; watcher.Created += Triggered; watcher.Error += ErrorOccured; watcher.NotifyFilter = NotifyFilters.LastWrite; watcher.IncludeSubdirectories = true; watcher.EnableRaisingEvents = true; One more thing that I found out that , new folder created event does not get triggered unless a new file created under the folder. do you guys know any work around for these issues ?

• Better understanding of my SQL transactions

  - by Slew Poke

  I just realized that my application was needlessly making 50+ database calls per user request due to some hidden coding -- hidden in the sense that between LINQ, persistence frameworks and events it just so turned out that a huge number of calls were being made without me being aware. Is there a recommended way to analyze individual transactions going to my SQL 2008 database, preferably with some integration to my Visual Studio 2010 environment? I want to be able to 'spy' on individual transactions being made, but only for certain pieces of my code, and without making serious changes to either the code or database.

• Changing Color with LinearLayout and TextView in Java (Android)

  - by Rob S.

  I'm a relatively new Android developer and I noticed what seems like an oddity to me that I'm hoping someone can explain. I have LinearLayout ll. This line of code fails for me when executed: ll.setBackgroundColor(R.color.white); However this line of code works: ll.setBackgroundResource(R.color.white); I assume its simply because I have white defined in my resources. However, I've also tried passing 0xFFFFFF in setBackgroundColor() and that doesn't work either. Similarly with my TextView text this line of code fails when executed: text.setTextColor(R.color.white); I can see my TextView so I know I initialized it correctly (like my LinearLayout which I can also see). So I guess my question boils down to: How do I properly use LinearLayout.setBackgroundColor() and TextView.setTextColor() ? Thanks a ton in advance. I've read through the docs and tried to find information online via googling and haven't come up with anything.

• Why do debug symbols so adversely affect the performance of threaded applications on Linux?

  - by fluffels

  Hi. I'm writing a ray tracer. Recently, I added threading to the program to exploit the additional cores on my i5 Quad Core. In a weird turn of events the debug version of the application is now running slower, but the optimized build is running faster than before I added threading. I'm passing the "-g -pg" flags to gcc for the debug build and the "-O3" flag for the optimized build. Host system: Ubuntu Linux 10.4 AMD64. I know that debug symbols add significant overhead to the program, but the relative performance has always been maintained. I.e. a faster algorithm will always run faster in both debug and optimization builds. Any idea why I'm seeing this behavior?

• Where can I find a deliberately insecure open source web application?

  - by Phil Laliberte

  As a developer, I've learned that I usually gain a better understanding of best/worst practices through experience. The area of web application security isn't really somewhere where my organization can afford to let developers learn through trial and error. So looking for a hands-on approach to knowledge sharing of best practices in web application security, I was thinking that it would be useful to have an open source application that was deliberately built to be insecure in order to help teach junior developers about application security. Does anyone out there know where to find something like this?

• Application disappears after starting - C++ linking managed code dll

  - by Axarydax

  Hello, we have a problem with our applications. We have recently upgraded our toolchain to Visual Studio 2010 and friends, it all works fine on Windows Vista + Windows 7 developer machines and Windows 7 customer machines. (all x86) Today we did a first installation to a client PC running Windows XP SP3 x86, and all applications linking managed code dll do not work. After starting the .exe seemingly nothing happens, no window pops up, no memory gets eaten, no task shows in task manager, nothing, nada. Event log is empty, everything is just as if the application returned to the OS right after the start. I am at loss about this, I really don't know how should I start even debugging this problem. I don't want to install VS2010 and everything onto a Windows XP box, I'd like to try something less time intensive first. This all is happening just to native C++ apps that link managed c++ DLL. Pure managed C# apps do work. Pure native C++ apps do work.

• How do I send an email from my webpage?

  - by Jordan S

  I am not a web developer but I do have a lot of programming experience in C# and Windows forms programming. On our company webpage my boss wants me to put in a textbox where visitors can submit a comment and press a submit button and that comment will be sent to an email address. Right now, our website uses just plain old html, no php or javascript or anything like that. I am wondering what is the simplest way to accomplish what I need? Can someone point me in the right direction? The website is hosted on an Apache server so I won't be able to use aspx.

• What is so great about STL?

  - by Zygrob

  Hello StackOverflow. I am a Java developer trying to learn C++. I have many times read over the web (including StackOverflow) that STL is the best collections library that you can get in *any* language. (Sorry, I do not have any citations atm) However after studying some STL, I am really failing to see what makes STL so special. Would you please shed some light on what sets STL apart from the collection libraries of other languages and make it the _best_ collection library? Thanks in advance, Zygr??b.

• How can I run a function anytime anything is animated with jQuery?

  - by WillyCornbread

  Hi - I have some jQuery animations in my code to slide divs up and down in response to some mouse clicks and other logic. This is all working just peachy, however in IE 6 some of the smaller icon images on the page don't slide along with the rest of the div for some strange reason. They kind of stay put then flicker into the new position and I've chalked this up to an IE6 'feature'. Considering that I have to support IE6, I wanted to just hide the icons anytime an animation started, and show them again when the queue was empty. I couldn't find a reference to any kind of events or hooks into the queue itself and I'd rather not add the hide code, then the show code to every animation as a callback. Thanks if you can help- b
