• ASP.NET radiobuttonlist onclientclick

  - by Jon

  I've noticed there is no OnClientClick() property for the radiobuttonlist in the ASP.NET control set. Is this a purposeful omissiong on Microsoft's part? Anyway, I've tried to add OnClick to the radio button list like so: For Each li As ListItem In rblSearch.Items li.Attributes.Add("OnClick", "javascript:alert('jon');") Next But alas, it doesn't work. I've even checked the source in firebug, and there is no javascript shown in the radiobuttonlist. Does anyone know how to get this very simple thing working? I'm using ASP.NET control adpaters so don't know if that has anything to do with it. (I wish asp.net/javascript would just work out the box!!!)

• VS2010 Beta 2 > Setup Project > Prerequisites > Missing .NET 3.0

  - by Adam Kane

  Hello, In Visual Studio 2010 Beta 2, in a Setup project, in Prerequisites, there's no option to include the .NET Framework 3.0 prerequisite. How do I change things so that it is an available option? My goal is to create an .msi installer that is launched by a Setup.exe. The Setup.exe should install .NET 3.0 if it's not there. The application that I'm installing uses .NET 3.0 Note: I've tried clicking the "Check Microsoft Update for more redistributable components", but .NET 3.0 wasn't there. Thanks! Adam

• Will a VB6 App Using wiaaut.dll work on Windows Vista or 7?

  - by Ross Waddell

  I downloaded the Windows Image Acquisition Automation Layer sdk redistributable from Windows and the VB6 app I wrote to capture still images from a DSLR, wia-compliant camera works great on Windows XP. Will the same app work on Windows Vista or 7? Microsoft says, "Windows Image Acquisition Automation Library v2.0 is only supported on Windows XP with Service Pack 1 installed.", but will the APIs work on newer OSs nonetheless? I really don't want to re-write the whole thing in C++ ... Is there any other option available to me if I want to keep using VB6 but want to support newer OSs?

• XML/XSD intellisense not working in Visual Studio 2010

  - by Jason

  I am working on xml and xsd files in VS 2010 but intellisense isn't working. Intellisense is working for the same files in VS 2008, however. When I type '<xs:' options like "attribute", "complexType", "simpleType", or "element" do not appear. Is there some difference between the VS 2008 and VS 2010 that I'm missing? I add an xsd file to my solution. All the proper namespaces are generated automatically as such: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="XMLSchema2" targetNamespace="http://tempuri.org/XMLSchema2.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema2.xsd" xmlns:mstns="http://tempuri.org/XMLSchema2.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema"> </xs:schema> The "xsdschema.xsd" is in the "C:\Program Files\Microsoft Visual Studio 10.0\xml\Schemas" directory. There is a check mark in the "Use" column in the XML Schemas dialog box.

• SQL - .NET - SqlParameters - AddWithValue - Are there any negative performance implications when Par

  - by hamlin11

  http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlparametercollection.addwithvalue.aspx I'm used to adding sql parameters to a sqlCommand using the add() function. This allows me to specify the type of the sqlParameter, but it requires another line to set the value. It's nice to use the AddWithValue function, but it skips the "specify the parameter type" step. I'm guessing this causes the parameters to be sent over as strings contained within single quotes (''), but I'm not sure. Is this the case, and does this cause significantly slower performance of the stored procedures? Note: I understand that it is nice to validate user data on the .NET side of things by specifying the data type for params -- I'm only concerned about reflection-type overhead of AddWithValue either on the .NET or SQL side.

• Trouble switching to the beta ajaxcontroltoolkit

  - by SLC

  I wanted to switch to the beta version to see if it fixes a problem I have been having, so I downloaded it and put two dll files into my bin folder. I deleted the old references to these files in visual studio, and re-added them. When I run my program I get an error: Microsoft JScript runtime error: AjaxControlToolkit requires ASP.NET Ajax 4.0 scripts. Ensure the correct version of the scripts are referenced. If you are using an ASP.NET ScriptManager, switch to the AjaxScriptManager in System.Web.Ajax.dll, or use the ToolkitScriptManager in AjaxControlToolkit.dll. I can't figure out how to fix this. I have the new System.Web.Ajax.dll added to visual studio, but I can't see any AjaxScriptManager anywhere... Any ideas?

• Unable to sync custom authentication with RIA services in SL3 + RIA implementation

  - by Nair

  I am developing SL3 + RIA services with custom authentication. I followed the example in http://code.msdn.microsoft.com/RiaServices/Release/ProjectReleases.aspx?ReleaseId=2661 to implement custom authentication. Based on the implementation, you first do login request from client to service. This request is async process. Noe the client GUI will start to bind data to SL controls using RIA services, which requires the authentication to be successful (by adding [RequireAuthentication] attribute). The trouble is, since you requested login from the main process, while it is doing authentication, the page control takes over and starts to bind data using RIA services. But the problem is authentication is not completed yet thus which ever the first service method data binding hits will fail with 'Access denied'. Bottom line is GUI is will not wait for authentication to be completed to start the data binding. My question is how do you handle this situation? Thanks,

• Visual Studio and SQL Server - correct installation sequence?

  - by cdonner

  I am rebuilding my development machine. This issue is not new to me, but I don't remember the solution. I started with VS 2008 Pro, then SQL 2008 Developer, then the SQL SP1, then VS SP1. The result is that I cannot open SSIS projects (see the error below). What is the correct order so that I can avoid the installation of SQL Server Express and still have all the features working? --------------------------- Microsoft Visual Studio --------------------------- Package Load Failure Package 'DataWarehouse VSIntegration layer' has failed to load properly ( GUID = {4A0C6509-BF90-43DA-ABEE-0ABA3A8527F1} ). Please contact package vendor for assistance. Application restart is recommended, due to possible environment corruption. Would you like to disable loading this package in the future? You may use 'devenv /resetskippkgs' to re-enable package loading. --------------------------- Yes No ---------------------------

• notepad sql Unicode and Non Unicode

  - by RBrattas

  Hi, I have a Microsoft Notepad flate file with data and Vertical Bar as column delimiter. I get following message: cannot convert between unicode and non-unicode string data types It seems it is my nvarchar(max) that creates my problem. I changed to varchar(max); but still the same problem. How do I insert my flate file into my SQL Server 2005? And in the SQL Server 2005 import and export wizard the flate file source advanced tab the OutputColumnWith is 50. Will that say my flate file column is max 50? I hope not because my column is more then 50... Thank you, Rune

• Visual C# 2010 MSVCR100.dll missing when opening a project...tried EVERYTHING!

  - by dlopeztt

  I installed Visual C# 2010 Beta 2 and I get this error every time I open a project: 'This application has failed to start because MSVCR100.dll was not found. Reinstalling the application may fix the problem' I uninstalled every VC runtime, .NET framework, C# on this computer. Then reinstalled Visual C# 2010 and the install went smoothly. Then I ran Microsoft Update. Still the same problem when I open a project. The project was created with VC# 2008. I'm running Windows 7 64-bit. Any idea how to fix this? I could only find people with the same problem while trying to Uninstall VS2010 and use a previous version.

• Windows "known folders": is there any one of them which is reliably read/write for all users on all

  - by Stabledog

  SHGetKnownFolderPath() and its cohorts accept one of the constants defined here (http://msdn.microsoft.com/en-us/library/dd378457%28v=VS.85%29.aspx ), returning the path to a directory. I'm looking for one of these folders which is reliably writable by all users (including LocalSystem) on XP, Vista, and Windows 7... but I think I'm striking out. It appears that, in fact, there is no single location on the hard drive anymore where you can put a file and be assured that all users can write to it on all these OS versions, without fiddling the permissions first. Is this true?

• "Executing SQL directly; no cursor" error when using SCOPE_IDENTITY/IDENT_CURRENT

  - by Chris

  There wasn't much on google about this error, so I'm askin here. I'm switching a PHP web application from using MySQL to SQL Server 2008 (using ODBC, not php_mssql). Running queries or anything else isn't a problem, but when I try to do scope_identity (or any similar functions), I get the error "Executing SQL directly; no cursor". I'm doing this immediately after an insert, so it should still be in scope. Running the same insert statement then query for the insert ID works fine in SQL Server Management Studio. Here's my code right now (everything else in the database wrapper class works fine for other queries, so I'll assume it isn't relevant right now): function insert_id(){ return $this->query_first("SELECT SCOPE_IDENTITY() as insert_id"); } query_first being a function that returns the first result from the first field of a query (basically the equivalent of execute_scalar() on .net). The full error message: Warning: odbc_exec() [function.odbc-exec]: SQL error: [Microsoft][SQL Server Native Client 10.0][SQL Server]Executing SQL directly; no cursor., SQL state 01000 in SQLExecDirect in C:[...]\Database_MSSQL.php on line 110

• When is Visual Studio 2010 expected to RTM?

  - by Chris Pietschmann

  Microsoft originally slated the final release build for April 12, 2010. Somasegar said the Visual Studio 2010 and .NET Framework 4 releases will now be pushed back "a few weeks." I know the version / product name says "2010", but that doesn't necessarily mean that it will RTM in 2010. After all VS'2008 RTM'd in November 2007. The last Beta of VS'2008 came out in July 2007, and it RTM'd in November. So based on the previous version that places VS'2010 to RTM in September 2010 at the very earliest since the first Beta just came out in May. Anyone have any other speculations?

• Understanding what SPARQL is

  - by user73119

  This is a terribly beginner series of questions, but after reading through a good 30 SPARQL tutorials I can't seem to wrap my head around what SPARQL is or how to begin using it. Is it executed on the client side? Is microsoft somehow going to be able to mess this up? Can you use a common relational database (SQL)? Are there particular resources you recommend over others for learning? Do you feel it is premature to begin investing myself in this? Best way to get set up and running to start tinkering? The RDFA examples I have seen are very inspiring. I am currently a big proponent of using microformats but would really like to take it further. I currently develop in PHP, but have only found a Java library.

• Where does Internet Explorer store saved passwords?

  - by Ian Boyd

  Where does Internet Explorer store saved passwords? And since this is a programming site, i'm not literally asking for the location where IE stores passwords, but which API ie uses to save passwords. At first i assumed that Microsoft was using the standard api: CredRead CredWrite which is used to save domain and generic program/web-site credentials. CredRead/CredWrite turn around and use CryptProtectData CryptUnprotectData to encrypt data with the current user's account. CredRead/CredWrite then store the data in some magical location, which contents you can see from the control panel: But i don't see IE passwords in there. So ie doesn't store passwords using CredRead/CredWrite. What api does IE use to store passwords, and if it uses CryptProtectData, where does it then store the protected data?

• Which ORM to use with SQL Azure?

  - by Jamie Chapman

  Just wondering what everyones thoughts on what ORM to use for SQL Azure? I'm fairly comfortable using LINQ-to-SQL and I believe it is possible to get it working with SQL Azure. However, from my understanding (correct me if I'm wrong), no further improvements will be made to Linq-to-SQL in future releases of the .NET framework? Alternatively, there is the entity framework... and further afield from the Microsoft Camp is NHibernate. Ideally, any additional suggestions made should be free or open source. I have seen Telerik's ORM but this of course, is a commercial product. I can get the definitions/benefits of each ORM myself by doing a Google search, but I was just interested in peoples opinions as to which ORM seems to work best for them (even if it is none of the above).

• Device Driver IRQL and Thread/Context Switches

  - by Christian Hoglund

  Hi, I'm new to Windows device driver programming. I know that certain operations can only be performed at IRQL PASSIVE_LEVEL. For example, Microsoft have this sample code of how to write to a file from a kernel driver: if (KeGetCurrentIrql() != PASSIVE_LEVEL) return STATUS_INVALID_DEVICE_STATE; Status = ZwCreateFile(...); My question is this: What is preventing the IRQL from being raised after the KeGetCurrentIrql() check above? Say a context or thread swithch occurs, couldn't the IRQL suddenly be DISPATCH_LEVEL when it gets back to my driver which would then result in a system crash? If this is NOT possible then why not just check the IRQL in the DriverEntry function and be done with it once for all?

• Unit Tests in Visual Studio 2010

  - by Ben

  Hi, i am trying to create a Unit test for a WinForm in a Visual Studio 2010 project. I add a new "Coded UI Test" to my project, open up the code file, then right click and select "Generate Code for Coded UI Test" - "Use Coded UI Test builder". I then start my application up, select "Record" on the UI Map control. I run my tests (in this case simply select a textbox, type in a random value, them click a button). I then select "Generate Code" from the UI Map control which generates the code which the test will use. When running this test, i get the error: Test method HelloWorldTest.CodedUITest1.CodedUITestMethod1 threw exception: Microsoft.VisualStudio.TestTools.UITest.Extension.UITestControlNotFoundException: The playback failed to find the control with the given search properties. Additional Details: TechnologyName: 'MSAA' ControlType: 'Window' Name: 'Form1' ClassName: 'WindowsForms10.Window' --- System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component. Does anyone know where i am going wrong? Thanks

• TypeLoadException at startup of WCF

  - by Kelly

  I get the following error long before I hit the breakpoint at Main(). System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information. at System.Reflection.Module._GetTypesInternal(StackCrawlMark& stackMark) at System.Reflection.Assembly.GetTypes() at Microsoft.Tools.SvcHost.ServiceHostHelper.LoadServiceAssembly(String svcAssemblyPath) There is a suggestion that it might be a configuration error, but I don't see it when comparing to a similar, working example. How do I "Retrieve the LoaderExceptions property" when it happens this early? Thanks!

• How to mix colors "naturally" with C#?

  - by crono

  I have to mix some colors in a natural way. This means blue + yellow = green blue + red = purple and so on. I got the colors as RGB-Values. When I try to mix them I got the right "RGB"-results like green + red = yellow yellow + blue = white but not the right "natural-wet-paint"-results. Any good idea how to mix RGB in a natural way? It would be great if someone knew a solution within the Microsoft.Xna.Framework.Graphics namespace but a generic solution would also help :)

  Hello.

Thank you!!

• Is there a list of known web crawlers?

  - by J. Pablo Fernández

  I'm trying to get accurate download numbers for some files on a web server. I look at the user agents and some are clearly bots or web crawlers, but many for many I'm not sure, they may or may not be a web crawler and they are causing many downloads so it's important for me to know. Is there somewhere a list of know web crawlers with some documentation like user agent, IPs, behavior, etc? I'm not interested in the official ones, like Google's, Yahoo's, or Microsoft's. Those are generally well behaved and self-indentified.

• Outlook 2003 View Control with C#

  - by Eleasar

  I want to embed a custom c# windows form (or WPF) user control into an outlook view. I am using Outlook 2003 and Visual Studio 2008. I did download an example for Outlook 2007 here: http://blogs.msdn.com/e2eblog/archive/2008/01/09/outlook-folder-homepage-hosting-wpf-activex-and-windows-forms-controls.aspx and also here: http://msdn.microsoft.com/en-us/library/aa479345.aspx I tested it and under 2007 it is working, but for 2003 i am getting the following error when i want to open the view: Could not complete the operation due to error 80131509 I can start it from Visual Studio, it is registering the folder just fine, debugging works and all that. It creates an HTML page that contains my type as an object parameter - but the Initialize method that should be called is either not present (not shown via JS) or it has some errors. The breakpoints for RegisterSafeForScripting are also never hit - maybe related to that. Thx in advance!
