• Visual SourceSafe (VSS): "Access to file (filename) denied" error

  - by tk-421

  Hi, can anybody help with the above SourceSafe error? I've spent hours trying to find a fix. I've also Googled the heck out of it but couldn't find a scenario matching mine, because in my case only a few files (not all) are affected. Here's what I found: only a few files in my project generate this error other files in the same directory (for example, App_Code has one of the problem files) work fine I've tried checking out from both the VSS client and Visual Studio another developer can check out the main problem file without any problems This sounds like a permission issue for my user, right? However: I found the location of one of the problem files in VSS's data directory (using VSS's naming format, as in 'fddaaaaa.a') and checked its permissions; everything looks fine and its permissions match those of other files I can check out successfully I can see no differences in the file properties between working and non-working files What else can I check? Has anyone encountered this problem before and found a solution? Thanks. P.S.: SourceGear, svn or git are not options, unfortunately. P.P.S.: Tried unsuccessfully to add tag "sourcesafe." EDIT: Hey Paddy, I tried to click 'add comment' to respond to your comment, but I'm getting a javascript error when loading this page in IE8 ("jquery undefined," etc.) so this isn't working. This is when checking out files, and yes, I've obliterated my local copy more times than I can remember. ;) EDIT 2: Thanks for the responses, guys (again I can't 'add comment' due to jQuery not loading, maybe blocked as discussed in Meta). If the problem was caused by antivirus or a bad disk, would other users still be able to check out the file(s)? That's the case here, which makes me think it's a permission issue specific to my account. However I've looked at the permissions and they match both other users' settings and settings on other files which I can check out.

• Can the Visual Studio (2010) Command Window handle "external tools" with project/solution relative p

  - by ee

  I have been playing with the Command Window in Visual Studio (View-Other Windows-Command Window). It is great for several mouse-free scenarios. (The autocompleting file "Open" command rocks in a non-trivial solution.) That success got me thinking and experimenting: Possibility 1.1: You can use the Alias commands to create custom commands Possibility 1.2: You can use the Shell command to run arbitrary executables and specify parameters (and pipe the result to the output or command windows) Possibility 2: A previously setup external tool definition (with project-relative path variables) could be run from the command window What I am stuck on is: There doesn't appear to be a way to send parameters to an aliased command (and thus the underlying Shell call) There doesn't appear to be a way to use project/solution relative paths ($SolutionDir/$ProjectDir) on a Shell call Using absolute paths in Shell works, but is fragile and high-maintenance (one alias for each needed use case). Typically you want the command to run against a file relative to your project/solution. It seems you can't run the traditional external tools (Tools-External Tools...) in the command window Ultimately I want the external tool functionality in the command window in some way. Can anyone see a way to do this? Or am I barking up the wrong tree? So my questions: Can an "external tool" of some sort (using relative project/solution path parameters) be used in the Command Window? If yes, How? If no, what might be a suitable alternative?

• Resources for setting up a Visual Studio/C++ development environment

  - by Tom H.

  I haven't done much "front-end" development in about 15 years since moving to database development. I'm planning to start work on a personal project using C++ and since I already have MSDN I'll probably end up doing it in Visual Studio 2010. I'm thinking about using Subversion as a version control system eventually. Of course, I'd like to get up and running as quickly as I can, but I'd also like to avoid any pitfalls from a poorly organized project environment. So, my question is, are there any good resources with common best practices for setting up a development environment? I'm thinking along the lines of where to break down a solution into multiple projects if necessary, how to set up a unit testing process, organizing resources, directories, etc. Are there any great add-ons that I should make sure I have set up from the start? Most tutorials just have one simple project, type in your code and click on build to see that your new application says, "Hello World!". This will be a Windows application with several DLLs as well (no web development), so there doesn't need to be a deploy to a web server kind of process. Mostly I just want to make sure that I don't miss anything big and then have to extensively refactor because of it. Thanks!

• Visual Studio 2008 having problems with namespaces when used as type in Generic coolection

  - by patrick

  I just upgraded last week from Visual Studio 2005 to 2008. I am having an issue with compiler resolving namespaces when I use a class as a type in a Generic collection. Intellisense recognizes the class and the compiler generates no errors when I use the class except when it is a type in a Generic collection declaration either as return type for a Property or as a parameter to a method. This is happening in my only project that is targeting the 3.5 framework, but changing the project containing the class to use the 3.5 framework doesn't fix the problem. Examples Compile fine MyClass myClass = new MyClass(); SortedList <DateTime,MyClass> listOfClasses = new SortedList<DateTime,MyClass> Compile error - Namespace could not be found public SortedList<DateTime,MyClass> ClassList { get; set; } private void DoSomethingToLists(SortedList<DateTime,MyClass> classList) Intellisense has no problem resolving the namespace, only the compiler. Is this a known bug or am I missing something obvious? Will SP1 fix it? I was able to create a new library containing just this class targeting 3.5 and am now able to successfully use this in both 3.5 and 2.0 projects. My guess is that even though I tried to change the target of my original library, since it was still referencing 2.0 projects there was some conflict.

• Visutal Studio Warning "Content is not allowed" in ASP.NET project

  - by pstar

  Hi, I am just started working as a programmer last month, so there will be plenty of newbie question come from me, stay tuned... I am now working on modify the provided template (from DevExpress) to create new web form using ASP.NET 2.0 on Visual Studio 2008. While the functionality of that web form is there, I am in the process of get rid of ninety something warning message, most of them come from the provided template. One of them puzzled me for a while is this one: "Warning 75 Content is not allowed between the opening and closing tags for element 'ClientSideEvents'." And here is the code: <dxe:ASPxListBox id="edtMultiResource" runat="server" width="100%" SelectionMode="CheckColumn" DataSource='<%# ResourceDataSource %>' Border-BorderWidth="0"> <ClientSideEvents SelectedIndexChanged="function(s, e) { var resourceNames = new Array(); var items = s.GetSelectedItems(); var count = items.length; if (count > 0) { for(var i=0; i<count; i++) _aspxArrayPush(resourceNames, items[i].text); } else _aspxArrayPush(resourceNames, ddResource.cp_Caption_ResourceNone); ddResource.SetValue(resourceNames.join(', ')); }"></ClientSideEvents> </dxe:ASPxListBox> I couldn't see anything wrong with the code myself, so please help me out here.

• Visual C++ function suddenly 170 ms slower (4x longer)

  - by Mikael

  For the past few months I've been working on a Visual C++ project to take images from cameras and process them. Up until today this has taken about 65 ms to update the data but now it has suddenly increased significantly. What happens is: I launch my program and for the first 30 or so iterations it performs as expected, then suddenly the loop time increases from 65 ms to 250 ms. The odd thing is, after timing each function I found out that the part of the code which is causing the slowdown is fairly basic and has not been modified in over a month. The data which goes into it is unchanged and identical every iteration but the execution time which is initially less than 1 ms suddenly increases to 170 ms while the rest of the code is still performing as expected (time-wise). Basically, I am calling the same function over and over, for the first 30 calls it performs as it should, after that it slows down for no apparent reason. It might also be worth noting that it is a sudden change in execution time, not a gradual increase. What could be causing this? The code is leaking some memory (~50 kb/s) but not nearly enough to warrant a sudden 4x slowdown. If anyone has any ideas I'd love to hear them!

• Doing TDD Silverlight 4 RC using Visual Studio 2010 RC

  - by user133992

  First I am glad to see better TDD support in VS2010. Support for generating code stubs from my tests is ok - not as good as more mature TDD plug-ins but a good start. I am looking for some best Silverlight 4.0 TDD practices. First Question: Anyone have links, recommendations? I know the new Silverlight Unit Test capabilities are much better (Jeff Wilcox's Mix Presentation). What I am focusing on right now is using TDD to develop pure Silverlight 4.0 Class Library projects - projects without a Silverlight UI project. I've been able to get it to work but not as cleanly as it should be. I can create an Empty VS project. Add A Silverlight 4 Class Library Project. Add a TestProject (not a silverlight Unit Test Project but a plain Test Project). Add a simple test in the Test Project such as: namespace Calculator.Test { [TestClass] public class CalculatorTests { [TestMethod] public void CalulatorAddTest() { Calc c = new Calc(); int expected = 10; int actual = c.Add(6, 4); Assert.AreEqual<int>(expected, actual); } } } Using the new Generate Type and Method from Test feature it will generate the following code in the Silverlight Project: namespace Calculator { public class Calc { public int Add(int p, int p_2) { throw new NotImplementedException(); } } } When I run the tests the first time it says the target assembly is Silverlight and not able to run test - Not exact text but the same general idea. When I change the implementation to: namespace Calculator { public class Calc { public int Add(int p, int p_2) { return p + p_2; } } } and re-run the test, it works fine and the test goes green. It also works for all other TDD code I generate after. I also get a warning Mark in the Test Project's reference to the Calculator Silverlight Class Library Assembly. Second Question: Any comments ideas if this just a bug in VS2010 RC or is Silverlight Class Library TDD not really supported. I have not created a Silverlight UI project or changed and build or debug settings so I have no idea what is hosting the silverlight DLL. Finally, some of the Silverlight Class Libraries I need to write will provide functionality that requires elevated Out-Of-Browser rights. Based on the above, it looks like I can use TDD Test Projects against regular Silverlight 4.0 Class Libraries, but I have no idea how I can TDD the elevated OOB functionality without also creating the UI component that gets installed. The UI piece is not really needed for the Library development and gets in the way of what I actually want to TDD. I know I can (and will) mock some of that functionality but at some point I will also need the real thing in my tests. Third Question: Any ideas how to TDD Silverlight 4.0 Class Library project that requires OOB elevated rights? Thanks!

• Very slow compile times on Visual Studio

  - by johnc

  We are getting very slow compile times, which can take upwards of 20+ minutes on dual core 2GHz, 2G Ram machines. A lot of this is due to the size of our solution which has grown to 70+ projects, as well as VSS which is a bottle neck in itself when you have a lot of files. (swapping out VSS is not an option unfortunately, so I don't want this to descend into a VSS bash) We are looking at combing projects (not nice, as we like the separation of concerns, but is a good opportunity to refactor away some dead wood). We are also looking at having multiple solutions to achieve greater separation of concerns and quicker compile times for each element of the application. This I can see will become a dll hell as we try to keep things in synch. I am interested to know how other teams have dealt with this scaling issue, what do you do when your code base reaches a critical mass that you are wasting half the day watching the status bar deliver compile messages UPDATE Apologies, I neglected to mention this is a C# solution. Thanks for all the cpp suggestions, but it's been a few years since I've had to worry about headers. At a distance I say I miss C++, but I'm not sure I want to go back EDIT: Nice suggestions that have helped so far (not saying there aren't other nice suggestions below, just what has helped) New 3GHz laptop - the power of lost utilization works wonders when whinging to management Disable Anti Virus during compile 'Disconnecting' from VSS (actually the network) during compile - I may get us to remove VS-VSS integration altogether and stick to using the VSS UI Still not rip-snorting through a compile, but every bit helps. Orion did mention in a comment that generics may have a play also. From my tests there does appear to be a minimal performance hit, but not high enough to sure - compile times can be inconsistent due to disc activity. Due to time limitations, my tests didn't include as many Generics, or as much code, as would appear in live system, so that may accumulate. I wouldn't avoid using generics where they are supposed to be used, just for compile time performance WORKAROUND We are testing the practice of building new areas of the application in new solutions, importing in the latest dlls as required, them integrating them into the larger solution when we are happy with them. We may also do them same to existing code by creating temporary solutions that just encapsulate the areas we need to work on, and throwing them away after reintegrating the code. We need to weigh up the time it will take to reintegrate this code against the time we gain by not having Rip Van Winkle like experiences with rapid recompiling during development.

• Bogus WPF / XAML errors in Visual Studio 2010

  - by epalm

  There are bogus errors hanging around, but at runtime everything works. Right now, I'm getting Cannot locate resource 'img/icons/silk/arrow_refresh.png'. I've got a simple UserControl called ImageButton (doesn't everyone?): <UserControl x:Class="WinDispatchClientWpf.src.controls.ImageButton" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d"> <Button Name="btnButton" Click="btnButton_Click"> <StackPanel Orientation="Horizontal"> <Image Name="btnImage" Stretch="None" /> <TextBlock Name="btnText" /> </StackPanel> </Button> </UserControl> Which does what you'd expect: [ContentProperty("Text")] public partial class ImageButton : UserControl { public String Image { set { btnImage.Source = GuiUtil.CreateBitmapImage(value); } } public String Text { set { btnText.Text = value; } } public double Gap { set { btnImage.Margin = new Thickness(0, 0, value, 0); } } public bool ToolBarStyle { set { if (value) { btnButton.Style = (Style)FindResource(ToolBar.ButtonStyleKey); } } } public bool IsCancel { set { btnButton.IsCancel = value; } } public bool IsDefault { set { btnButton.IsDefault = value; } } public event RoutedEventHandler Click; public ImageButton() { InitializeComponent(); } private void btnButton_Click(object sender, RoutedEventArgs e) { if (Click != null) { Click(sender, e); } } } Where CreateBitmapImage is the following: public static BitmapImage CreateBitmapImage(string imagePath) { BitmapImage icon = new BitmapImage(); icon.BeginInit(); icon.UriSource = new Uri(String.Format("pack://application:,,,/{0}", imagePath)); icon.EndInit(); return icon; } I can't see the design view of any xaml file that uses an ImageButton like such: <Window foo="bar" xmlns:wpfControl="clr-namespace:MyProj.src.controls"> <Grid> <wpfControl:ImageButton ToolBarStyle="True" Gap="3" Click="btnRefresh_Click" Text="Refresh" Image="img/icons/silk/arrow_refresh.png" /> </Grid> </Window> Why is VS complaining?

• Problem with Command Pattern under Visual Studio 2008 (C++)

  - by D.Giunchi

  Dear All, I've a problem with this pattern under c++ on VS 2008. The same code has been tested in gcc (linux, mac and mingw for widnows) and it works. I copy/paste the code here: class MyCommand { public: virtual void execute() = 0; virtual ~MyCommand () {}; }; class MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyOperationDerived : public MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyUndoStackCommand : public MyCommand { public: typedef void(MyOperation::*Action)(); MyUndoStackCommand(MyOperation *rec, Action action); /*virtual*/ void execute(); /*virtual*/ ~MyUndoStackCommand(); private: MyOperation *myReceiver; Action myAction ; }; in cpp: #include "MyUndoStackCommand.h" #include "MyOperation.h" MyUndoStackCommand::~MyUndoStackCommand() { } MyUndoStackCommand::MyUndoStackCommand(myOperation *rec, Action action): myReceiver(rec), myAction(action) { } void MyUndoStackCommand::execute() { ((myReceiver)->*(myAction))(); } use in main.cpp: MyReceiver receiver; MyUndoStackCommand usc(&receiver, &MyOperation::DoIt); usc.execute(); when I debug under visual studio only if I set inside MyUndoStackCommand, directly myAction = &MyOperation::DoIt , it works, otherwise not. Any advice? thank you very much, dan Edit: The following code compiles with g++ - changes by Neil Butterworth flagged as //NB. class MyCommand { public: virtual void execute() = 0; virtual ~MyCommand () {}; }; class MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyOperationDerived : public MyOperation { public: virtual void DoIt() {}; //I also write it not inline }; class MyUndoStackCommand : public MyCommand { public: typedef void(MyOperation::*Action)(); MyUndoStackCommand(MyOperation *rec, Action action); /*virtual*/ void execute(); /*virtual*/ ~MyUndoStackCommand(); private: MyOperation *myReceiver; Action myAction ; }; MyUndoStackCommand::~MyUndoStackCommand() { } MyUndoStackCommand::MyUndoStackCommand(MyOperation *rec, //NB Action action) : myReceiver(rec), myAction(action) { } void MyUndoStackCommand::execute() { ((myReceiver)->*(myAction))(); } int main() { MyOperation receiver; //NB MyUndoStackCommand usc(&receiver, &MyOperation::DoIt); usc.execute(); }

• Visual Basic 2010 Language Enhancements

  Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10 (also referred to as Visual Basic 2010). Previously, the C# and Visual Basic programming languages were managed by two separate teams within Microsoft, which helps explain why features found in one language was not necessarily found in the other. For example, C# 3.0 introduced <a href="http://weblogs.asp.net/scottgu/archive/2007/03/08/new-c-orcas-language-features-automatic-properties-object-initializers-and-collection-initializers.aspx"><i>collection initializers</i></a>, which enable developers to define the contents of a collection when declaring it; however,

• SQL SERVER – Automated Type Conversion using Expressor Studio

  - by pinaldave

  Recently I had an interesting situation during my consultation project. Let me share to you how I solved the problem using Expressor Studio. Consider a situation in which you need to read a field, such as customer_identifier, from a text file and pass that field into a database table. In the source file’s metadata structure, customer_identifier is described as a string; however, in the target database table, customer_identifier is described as an integer. Legitimately, all the source values for customer_identifier are valid numbers, such as “109380”. To implement this in an ETL application, you probably would have hard-coded a type conversion function call, such as: output.customer_identifier=stringToInteger(input.customer_identifier) That wasn’t so bad, was it? For this instance, programming this hard-coded type conversion function call was relatively easy. However, hard-coding, whether type conversion code or other business rule code, almost always means that the application containing hard-coded fields, function calls, and values is: a) specific to an instance of use; b) is difficult to adapt to new situations; and c) doesn’t contain many reusable sub-parts. Therefore, in the long run, applications with hard-coded type conversion function calls don’t scale well. In addition, they increase the overall level of effort and degree of difficulty to write and maintain the ETL applications. To get around the trappings of hard-coding type conversion function calls, developers need an access to smarter typing systems. Expressor Studio product offers this feature exactly, by providing developers with a type conversion automation engine based on type abstraction. The theory behind the engine is quite simple. A user specifies abstract data fields in the engine, and then writes applications against the abstractions (whereas in most ETL software, developers develop applications against the physical model). When a Studio-built application is run, Studio’s engine automatically converts the source type to the abstracted data field’s type and converts the abstracted data field’s type to the target type. The engine can do this because it has a couple of built-in rules for type conversions. So, using the example above, a developer could specify customer_identifier as an abstract data field with a type of integer when using Expressor Studio. Upon reading the string value from the text file, Studio’s type conversion engine automatically converts the source field from the type specified in the source’s metadata structure to the abstract field’s type. At the time of writing the data value to the target database, the engine doesn’t have any work to do because the abstract data type and the target data type are just the same. Had they been different, the engine would have automatically provided the conversion. ?Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Database, Pinal Dave, SQL, SQL Authority, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, SQLAuthority News, T SQL, Technology Tagged: SSIS

• My Favorite New Features in Visual Studio 2010

  On Tuesday, April 13th, Microsoft released <a href="http://www.microsoft.com/visualstudio">Visual Studio 2010</a> and the .NET Framework 4.0 (which includes ASP.NET 4.0). To get started with Visual Studio 2010 you can either <a href="http://msdn.microsoft.com/en-us/vstudio/bb984878.aspx">download a trial version</a> of one of the commercial editions or you can go grab the free <a href="http://www.microsoft.com/express/Web/">Visual Web Developer 2010 Express Edition</a>. The Visual Studio 2010 user experience is noticeably different than with previous versions.

• Introducing .NET 4.0 with Visual Studio 2010 by Alex Mackey - Book review

  - by Malisa L. Ncube

  Alex (http://simpleisbest.co.uk/) does a very good job in covering the new features of .NET 4.0 and Visual Studio 2010. His focus is on the developers that have experience in development using previous versions of Visual Studio, more specifically Visual Studio 2008.     The following are my views towards his book. 1. Scope / Coverage Even as the book is labeled as introduction, it is covers a broad spectrum of technologies, features and references that are focused into helping a developer quickly decide what to use in the new .NET framework. a. Content The content included covers as much as possible the new additions that are included in the new .NET version 4.0. He shows the Visual Studio 2010 new features and quickly shows how to extend it using Managed Extensibility Framework. Some of my favorites are parallel debugging enhancements. The author delves into JQuery, which Microsoft has decided to support. Some of the very interesting content is on the out-of-band releases including ASP.NET MVC, Windows Azure Silverlight 3 and WCF Data Services. b. What is not included? Windows Phone 7 Series. This was only talked about in the MIX10. The data may not have been available at the time of writing. Microsoft Pinpoint (Microsoft code name "Dallas") Windows Embedded development. c. Table of Contents Chapter 1: Introduction Chapter 2: Visual Studio IDE and MEF Chapter 3: Language and Dynamic Changes Chapter 4: CLR and BCL Changes Chapter 5: Parallelization and Threading Enhancements Chapter 6: Windows Workflow Foundation 4 Chapter 7: Windows Communication Foundation Chapter 8: Entity Framework Chapter 9: WCF Data Services Chapter 10: ASPNET Chapter 11: Microsoft AJAX Library Chapter 12: jQuery Chapter 13: ASPNET MVC Chapter 14: Silverlight Introduction Chapter 15: WPF 4.0 and Silverlight 3.0 Chapter 16: Windows Azure 2. Depth Avoids getting into depth on the topics presented, to present the new concepts in assumption of the developer’s existing knowledge. Code samples are on book and exist mostly as snippets and very easy to follow. There are no downloadable examples. 3. Complexity The book is written in a very simple way and easy to follow. There are no irrelevant intimidating details. So it’s a book that you can grab and never put down until you’ve finished reading the entire book. 4. References The author includes reference links to blogs, Wikis and a lot of online resources including the MSDN documentation, which is a very convenient strategy to avoid flooding the reader with details which may not be of interest to them. Most sites do not use url routing and that is really not nice. There are notes from interviews between the author and people behind the new technologies, in which they explain what some specific areas that need clarifications and what their future views are in relation to the features they are working on. 5. Target The author targets experts that want to make a transition from .NET 3.5 to 4.0. Some obvious 3.5 features have been purposely excluded from the text 6. Overrall It is evident that the author has made extensive research into the breadth of what MS is working on, in relation to .NET and Visual Studio and has also been watching the online community. What I would like to see in the next edition are some details on OData protocol, Expression Blend 4 and Embedded development and Windows Phone development. I should say I’m one of the beneficiaries of this book. Excellent work Alex.   Technorati Tags: .NET,Book-Review,Visual Studio

• Windows CE: SDK Doesn’t Show up in Visual Studio 2008

  - by Bruce Eitman

  A customer recently contacted me because after installing an SDK it didn’t show up in Visual Studio 2008.  So being a good vendor I installed VS2008 and then installed the SDK – no problem the SDK showed up and I could create projects based on it. I let the customer know that the SDK definitely works with VS2008. The customer got back to me and asked what OS I was using. Hmm, how could that play into this? I told him that I use Windows XP, and it turned out that he is way more modern than I am and is using both Windows Vista and 7. The customer opened a support case with Microsoft. The answer turns out to be that the SDK install requires the user to be logged on as an administrator when installing on Windows Vista and 7 for the SDK to show up in Visual Studio 2008. This problem does not seem to exist for Visual Studio 2005 on those operating systems. The actual instructions from Microsoft Support are: 1)      Make sure Visual Studio 2008 is not running. I also shut down the device emulator manager but you may not be using that. 2)      Open a “Visual Studio 2008 Command Prompt” as Administrator. On Windows 7 just right click the short cut and pick the “Run as administrator” option. 3)      Enter the following command: msiexec /log SDKInstallLog.txt /package <the path to your .msi file> 4)      When asked if you wish to do a custom or complete install pick custom 5)      Instruct the installer to omit the installation of the documentation. This was something I found about CE 6 SDK installation issue and may have no bearing upon your problem but I did it anyway. 6)      Install   Copyright © 2010 – Bruce Eitman All Rights Reserved

• Rouen Business School builds its entire back office UI with Visual WebGui

  - by Webgui

  Two years ago, Rouen Business School (AMBA accredited institution located in Rouen, Normandy, France) decided to develop and implement a proprietary information system in-house. The objective was to administer all the data encompassed by a classic 3500 Students business school: from on-line application forms to the registration system including financial information, scheduling, grades management, etc. The development team at Rouen Business School chose Visual WebGui for the UI. “When we tested the Visual WebGui solution we were really amazed and enthusiastic. It was exactly the kind of solution we were looking for… The great performance of the solution allows us to manage a large amount of information with no delay with a very positive feedback at the user end,” said Stéphane Henry the IT Project Manager of the school.   As a result of the fast development, easy deployment, performance, and professional design that the team experienced with Visual WebGui, the entire back office of Rouen Business School information system was chosen to be developed with the Visual WebGui framework “and after two years we do not see any reason to change this,” commented Stéphane Henry who added that “all the original requirements were satisfied using Visual WebGui.” You can read the full Case study here >

  - by Jagannath

  I have Windows 7 64-bit Professional on my PC. When using English language, the visual effects are turned on. When I use Telugu LIP (India), the visual effects are turned off every time I reboot my PC. When I say visual effects, I don't mean the aero effects. The maximize and minimize effects are not felt. The effects don't show up though the check boxes are checked. Find the image showing the check boxes are checked but the effects not being showed up p. UPDATE: I recreated the account and now the effects are restored properly. UPDATE: Yes it is. This is a standard account. The surprising thing is,the check boxes are checked but still no animations. Once I make the apply button enable, the animations show up again.
