• Will Delphi be there in future ?

  - by devdude

  Yes, there is a version 2009. I know Delphi has a big community since years (10 plus)and I believe you could create native windows exe before Visual Basic got to speed (with all its dll's nighmare). But is it future-proof ? Is there a need or market for a non-crossplatform native all-in-one executable ? Will Embarcardero ex Codegear ex Borland continue to push it ? Why is it so expensive ? Who (non company) can afford it, in order to learn it ?

• Is using the keyword var bad in C# 2.0?

  - by Patrick

  I read an article about using C# 3 features in C# 2 where you can for instance type var x = 2; and even if the project is a 2.0 project, the Visual Studio 2008 compiler picks it up and generates the same code as it would if you type int x = 2. But what I don't get is, should you not do this in some cases? I always thought that the var keyword didn't arrive until C# 3.. If the compiler generates the same code and I can type C# 3 code and C# 2 code exactly the same, what is the differance really, because the CLI is the same, right? Quote from the link above Behind the scenes, the compiler generate regular .NET 2.0 code. Is there any difference between .NET 2.0 code and .NET 3 code?

• embed ttf as embeded resource can't reference it

  - by HoNgOuRu

  Hi, I've just added a ttf file to the project (c# 2008 express) as "file" and build option to embeded resource. I'm having problems when trying to set this font like this: (I know the next line is wrong...) this.label1.Font = AlarmWatch.Properties.Resources.Baby_Universe; Error 1 Cannot implicitly convert type 'byte[]' to 'System.Drawing.Font' C:\Users\hongo\Documents\Visual Studio 2008\Projects\AlarmWatch\AlarmWatch\Form1.Designer.cs 57 32 AlarmWatch I know it is byte[] cause I've set the option build as embeded resource, but...comparing with this line that is correct "this.label1.Font = new System.Drawing.Font("OCR A Extended", 24F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));" How can I set this.label1 to use the new font??? thanks

• Using makecert for Development SSL

  - by John

  Here's my situation: I'm trying to create a SSL certificate that will be installed on all developer's machine's, along with two internal servers (everything is non-production). What do I need to do to create a certificate that can be installed in all of these places? Right now I've got something along these lines, using the makecert application in Microsoft Visual Studio 8\SDK\v2.0\Bin: makecert -r -pe -n "CN=MySite.com Dev" -b 01/01/2000 -e 01/01/2033 -eku 1.3.6.1.5.5.7.3.1 -ss Root -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12 mycert.cer However, I'm not sure as to how to place this .cer file on the other computers, and when I install it on my local machine IIS, everytime I visit a page via https:, I get the security prompt (even after I've installed the certificate). Has anyone done this before?

• WPF Animation of border width

  - by Dave Perry

  I've got a dockpanel on my ui as follows; <DockPanel> <Border DockPanel.Dock="Top">Header</Border> <Border DockPanel.Dock="Bottom">My footer</Border> <Border DockPanel.Dock="Left">Menu</Border> <Border>Content</Border> </DockPanel> What I want to do is to have a storyboard animation to show / hide the Menu on the left-hand side. I've got my border to increase the width when it has loaded but I want a way to close / reopen it. I need a button somewhere but I want this to trigger the animation in the border control rather than itself. Ideally I was thinking of something like the Toolbox / Server Explorer in visual studio. Does anyone have any pointers / examples for getting started? Thanks

• How to add a Web Reference to a SSL web service?

  - by Matt W

  Hi, I have a web service in a C#/3.5 project which has been running fine. This is until I set the "SSL port" in IIS to 443 and set the "IIS - Directory Security - Secure Communications - Require secure channel (SSL)" option to true. Now, the web reference cannot be updated and I cannot add a new web reference to the web service in that site. When I try to view the service in a browse using just HTTP I get the "This page must be viewed over a secure channel" and when viewed with HTTPS on the front I get "This web page not available." Could someone tell me how to get a Web Reference added using Visual Studio to this secure web service, please? Thanks, Matt.

• Silverlight Project Not Updating When Ran

  - by Redburn

  I'm currently developing with VS2010 RC and Silverlight 4 and ran into small problem. My project when ran, would show a version I had built about 4 hours ago. (I built the project using the Business Template) The project itself will not update, meaning all the forms, and controls. I did the following: Restarted my computer Restarted Visual Studio Deleted the xap file in the ClientBin folder on the web side Deleted the Generated_Code folder on the client side Deleted the xap file from the Debug folder on the client side Opened the Solution's Configuration Manager and ensuring both my web and client projects are checked. Rebuilt, built, and cleaned every combination of the different projects and solution Is there a known bug or something else I can try?

• ASP.NET-MVC2 Preview 1: Are There Any Breaking Changes?

  - by Jim G.

  I was following Steven Sanderson's 'Pro ASP.NET MVC Framework' book. On page 132, in accordance with the author's recommendation, I downloaded the ASP.NET MVC Futures assembly, and added it to my MVC project. Then, without encouragement from the author, I downloaded, installed, and incorporated the ASP.NET MVC2 Preview 1 dlls into my project. Now, I can no longer load the website. That is, when I hit F5 in Visual Studio, I get this error. In retrospect, I think it was a really bad idea to assume that ASP.NET MVC2 Preview 1 would only be additive; but I'd like other people to weigh in. Has anyone noticed any breaking changes in ASP.NET MVC 2 Preview 1? Also - Has anyone noticed any changes that impact Castle Windsor? Also, please let me know if I should be mindful of IIS6 vs. IIS7 ramifications.

• Navingating to an .html file in the assembly

  - by Joel

  I’m working with the WPF WebBrowser control to navigate to a html page hosting Silverlight. It seems I cannot use the NavigateToString or NavigateToStream method since I have Silverlight content. The html content loads fine but not Silverlight. So I think I’ll have to use the Navigate method which takes an Uri. Now I html page I’d like to navigate to is in a .html file in my Visual Studio project so I will have to have a local uri of some sort. I don’t want the html file to be copied to the output folder since I don’t want to distribute it separately; I want it to be somehow included in the assembly. The problem is that the WebBrowser control doesn’t seem to allow relative Uris or pack://application: uris. How could I accomplish navingating to an .html file in the assembly?

• Android: How to restore List data when pressing the "back" button?

  - by Rob

  Hi there, My question is about restoring complex activity related data when coming back to the activity using the "back" button". Activity A has a ListView which is connected to ArrayAdapter serving as its data source - this happens in onCreate(). By default, if I move to activity B and press "back" to get back to activity A, does my list stay intact with all the data or do I just get visual "copy" of the screen but the data is lost? What can I do when more than activities are involved? Let's say activity A starts activity B which starts activity C and then I press "back" twice to get to A. How do I ensure the integrity of the A's data when it gets back to the foreground? PrefsManager does not seem to handle complex object very intuitively. Thanks, Rob

• JNI_CreateJavaVM: Buffer overrun if I throw an exception in case of failure

  - by Dominik Fretz

  Hi, In a C++ project, I use the JNI invocation API to launch a JVM. I've done a little wrapper arount the JVM so I can use all the needed parts in a OO fashion. So far that works great. Now, if the JVM does not start (JNI_CreateJavaVM returns a value < 0) I'd like to raise an exception within my C++ code.But if I throw an exception after JNI_CreateJavaVM, I get a buffer overrun. If I raise the exception without the JNI_CreateJavaVM call, it works as expected. Does anyone have a clue on what the issue could be here? Or how to debug this? Environment: Windows, Visual Studio 2008 JDK: jrockit27.6jdk16005, but happens with SUN stock one as well Cheers Dominik

• SQL Server won't perform regular expression validation on XML column

  - by Kirk Broadhurst

  Hi I have an XML column in my table which contains this xsd snippet: <xsd:element name="Postcode" minOccurs="0"> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:pattern value="^[0-9]{4}$" /> </xsd:restriction> </xsd:simpleType> </xsd:element> The regular expression should require a string containing 4 numerical digits. It validates perfectly in Visual Studio and is a correct regular expression. SQL Server, on the other hand, won't accept it. The error message I receive is: XML Validation: Invalid simple type value: '1234'. Location: / * : Donor[1]/*:Postcode[1]. I have an email address regex working fine, but can't get this simple numerical regex to work.

• .NET 4.0 build issues on CI Server

  - by DMcKenna

  Anybody manage to get .net 4.0 applications compiling on a CI server without installing visual studio 2010 on a CI server. No SDK exists for .net 4.0. Have installed .NET 4.0 on CI Server. Msbuild.exe works for simple projects and give the following warning (GetReferenceAssemblyPaths target) - C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(847,9): warning MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.0" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in placeof reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.

• Sharepoint Foundation 2010 installation problems

  - by Robert Koritnik

  I'm having problems installing development machine for Sharepoint (Foundation) 2010. This is what I did so far on the same machine: Installed a clean Windows 7 x64 with 4GB of RAM without being part of any domain. Just a simple standalone machine. Enabled IIS related features as described here except IIS6 related ones (two of them) Installed SQL Server 2008 R2 Development Edition (DB Engine and Writer being enabled but not SQL Agent) Installed Visual Studio 2010 Premium Started installing Sharepoint Foundation 2010 with first extracting files, changing config to enable Windows 7 installation and then installed it as Server Farm (then Complete) to avoid installing SQL Express. Created a separate SPF_CONFIG local user with Logon on as a service right. Opened SPF Management Shell and run New-SPConfigurationDatabase so I am able to use a non-domain username (SPF_CONFIG that I created in the previous step) But all I get is this: The outcome after this error is: Database Sharepoint2010Config is created User SPF_CONFIG is added to SQL Server and attached to this newly created database as dbowner and checking SQL server security logins this user has following rights: dbcreator securityadmin public

• Why is a report, in SSRS, when viewed in preview mode looks different when viewed in print layout mo

  - by Dean

  I have a report that was originally built in report builder and then imported into Visual Studio to add some other formating to it. The report has a header and a body section. In the body section there is a column that shows commission and the commission is subtotaled for each sales person. There is a page break for each sales person as well. When I preview the report, the subtotal appears as it should for each sales person, but when I either look at it in print layout mode or send it to the printer, the subtotal appears in the body section of the next page, which is the next sales person. Why is it behaving like this and how can I fix this? Thanks.

• Silverlight solution builds in VS2008 but fails with MSBuild

  - by Chris Nicola

  I have a Silverlight solution that I want to create a build script for. I have a simple script that looks like this call "c:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat" msbuild %CD%\V1\Incentive.sln /target:Rebuild /property:Configuration=DEBUG;WarningLevel=2 msbuild %CD%\UI\IncentiveUI.sln /target:Rebuild /property:Configuration=DEBUG;WarningLevel=2 pause However when I run this I get a failure, with some complaints about classes that are in a project with linked files: http://pastebin.com/JRE3tWfh This solution compiles fine in VS2008 so I can't figure out what the problem is. I have to guess something is wrong with the way I am using msbuild here.

• What are the causes and solutions of exception code c0000005 in mscorwks.dll?

  - by Erick

  The exception code c0000005 is thrown from mscorwks.dll when the application is run on Windows Server 2008 R2. Other platforms (WinXP, Server 2003 R2, Windows 7 32-bit and 64-bit) do not present this exception. The event log from a single execution has many of the following event with event ID 1023 raised by the .NET Runtime: .NET Runtime version 2.0.50727.4952 - Fatal Execution Engine Error (7383851A) (80131506) The application itself makes use of a SOAP interface generated by visual studio from a wsdl, a COM object with an embedded interop, and is targeting .Net 4. sfc /scannow was run and found no problems with system files on the affected system. What trouble shooting can be done to identify a solution?

• How do I pre-empt IIS StaticFileHandler with my own HttpHandler

  - by Hmobius

  Hi there, I'm building a website referencing an assembly that contains several js scripts as embedded resources, some controls which use those scripts and a 'HttpResourcesHandler' that knows how to retrieve those embedded scripts when asked for them. In web.config I have an entry in the section that reads <add verb="*" path="/embedded/controlscripts/*" validate="false" type="CWeb.Controls.Web.HttpResourcesHandler, CWeb.Controls.EditBox" /> This control adn the website work absolutely fine when debugging with the Visual Studio web development server, but if I then switch the website to run under IIS (v7 - I'm running Vista and there appears to be no problem with debugging the site using IIS 5 or 6), the control can no longer access the scripts. I get a HTTP 404.0 error screen indicating the StaticFileHandler cannot find the file. I know that - it's embedded. So the StaticFileHandler appears to be grabbing the request for the script before my own and returning a 404. How do I tell IIS to use my own resource handler for the embedded/controlscripts directory rather than the staticfilehandler? I'm running the website in classic mode by the way.

• XSD NewDataSet Namespace?

  - by Ian

  I'm running XSD on an XML file and getting something strange. Depending on the depth of elements it produces a 'NewDataSet' element which will then is prefixed in Visual Studio to my auto-generated classes which is something I don't want. I've got quite a complex structure and am just trying to add a simple version element or attribute which is causing the problem. The simplest demo I could come up with is this. <A> <B>Text</B> </A> Running this through XSD says there is an element called 'NewDataSet' which may or may not appear and will prefix namespaces. <A> <B> <C>Text</C> </B> </A> This example works as expected and there is no magic 'NewDataSet' element in the generated XSD file.

• Creating an installer with WPF forms, packaged files and custom setup actions in C#

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• Coordinating the logging output from a web app installed in a SharePoint farm.

  - by Kelly French

  We are deploying web parts to SharePoint 2007 and would like to include logging (log4net). The ideal solution would be to use a database appender to avoid the problems with knowing which actual server is executing the web part. This questions has been helpful: http://stackoverflow.com/questions/219668/sharepoint-and-log4net. I've got log4net working in a stand-alone web app using Visual Studio dev server using the web.config for the log4net settings and a file appender for the output. I'd like to transition to SharePoint and still use the log file output so I can make sure it's all working first, then change the config around to log to a database. Is this going to be too much trouble? How have other developers added log4.net into their solutions for SharePoint?
