• Can't find .Net 2.0 XML Schema

  - by Zach Smith

  I'm currently setting up an application config for a WPF application written in .Net 4.0. The connection string in the app.config is encrypted like so: <connectionStrings configProtectionProvider="DataProtectionConfigurationProvider"> <EncryptedData> <CipherData> <CipherValue>CypherValue</CipherValue> </CipherData> </EncryptedData> </connectionStrings> To use the EncryptedData element I need to include the XMLNS "http://schemas.microsoft.com/.NetConfiguration/v2.0". Attempting to include it produces an error as the schema cannot be found. Is there a way to include the schema or perhaps a different element I could use instead of EncryptedData?

• MSI File/Registry failures to Windows Server 2008/Windows 7

  - by Luca

  I'm trying to deploy an application on Windows Server 2008 (SP2 x64) and Windows 7 (x64), using VS2005 Installer Project. The MSI version (I think) it the 2.0. Everything works fine, except that some registry keys and some files are not copied on the install machine. The MSI system doesn't notify about nothing (and I don't know whether MSI logs its operations). Are there incompatibilities between my MSI installer project and these new OSes? It seems to me that the OS protect itself for being modified in some part. For example, I'm trying to set the registry keys: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\WinLogon\SpecialAccounts\UserList\User but it is not created. In the same installer there are many other keys, which are created like expected (as they always did before on Windows XP and Windows Server 2003). What's going on?

• What is application and process?

  - by Lu Lu

  An application consists of one or more processes. A process, in the simplest terms, is an executing program. One or more threads run in the context of the process. A thread is the basic unit to which the operating system allocates processor time. A thread can execute any part of the process code, including parts currently being executed by another thread. Source: http://msdn.microsoft.com/en-us/library/ms684841%28VS.85%29.aspx I understand about thread, but I can't distinguish between application & process. What is application? What is process? How do an application have more than 1 process? And please give me an example in C#. Thanks.

• Get all window handles for a process

  - by Jeremy

  Using Microsoft Spy++, I can see that the following windows that belong to a process: Process XYZ window handles, displayed in tree form just like Spy++ gives me: A B C D E F G H I J K I can get the process, and the MainWindowHandle property points to the handle for window F. If I enumerate the child windows using I can get a list of window handles for G through K, but I can't figure out how to find the window handles for A through D. How can I enumerate windows that are not children of the handle specified by MainWindowHandle of the Process object? To enumerate I'm using the win32 call: [System.Runtime.InteropServices.DllImport(strUSER32DLL)] public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

• How do you do dynamic script evaluation in C#?

  - by Deane

  What is the state of dynamic code evaluation in C#? For a very advanced feature of an app I'm working on, I'd like the users to be able to enter a line of C# code that should evaluate to a boolean. Something like: DateTime.Now.Hours > 12 && DateTime.Now.Hours < 14 I want to dynamically eval this string and capture the result as a boolean. I tried Microsoft.JScript.Eval.JScriptEvaluate, and this worked, but it's technically deprecated and it only works with Javascript (not ideal, but workable). Additionally, I'd like to be able to push objects into the script engine so that they can be used in the evaluation. Some resources I find mentioned dynamically compiling assemblies, but this is more overhead than I think I want to deal with. So, what is the state of dynamic script evaluation in C#? Is it possible, or am I out of luck?

• Metatool for automatic xml code generation

  - by iceman

  I want to develop a programming tool for developers which can do automatic xml code generation for specifying a GUI design and its controls. The aim is to allow non-programmers specify GUI controls(which in this case perform higher level task unlike WinForms ) from a GUI. So the xml code generated is essentially an internal representation which programmers can understand and further use in any automatic GUI generator. So the workflow is GUI(non-programmers)-xml(for programmers)-GUI(non-programmers). Is there a Microsoft project similar to this?

• .Net SvcUtil: attributes must be optional

  - by Michel van Engelen

  Hi, I'm trying to generate C# code classes with SvcUtil.exe instead of Xsd.exe. The latter is giving me some problems. Command line: SvcUtil.exe myschema.xsd /dconly /ser:XmlSerializer Several SvcUtil problems are described and solved here: http://blog.shutupandcode.net/?p=761 One problem I can't solve is this one: Error: Type 'DatafieldDescription' in namespace '' cannot be imported. Attributes must be optional and from namespace 'http://schemas.microsoft.com/2003/10/Seri alization/'. Either change the schema so that the types can map to data contract types or use ImportXmlType or use a different serializer. ' I changed <xs:attribute name="Order" use="required"> to <xs:attribute name="Order" use="optional"> and <xs:attribute name="Order"> But the error remains. Is it possible to use attributes, or do I have to delete them all (in that case, this excercition is over)?

• Documentation concerning platform-specific macros in Linux/POSIX

  - by Nubok

  When compiling a C/C++ program under Windows using Visual Studio (or a compiler that tries to be compatible) there is a predefined macro _WIN32 (Source: http://msdn.microsoft.com/en-us/library/b0084kay.aspx) that you can use for platform-specific #ifdef-s. What I am looking for is an analogon under Linux: a macro which tells me that I am compiling for Linux/an OS that claims to be (more or less) POSIX-compatible. So I looked into gcc documentation and found this: http://gcc.gnu.org/onlinedocs/cpp/System_002dspecific-Predefined-Macros.html Applied to my program, the following macros (gcc 4.4.5 - Ubuntu 10.10) looked promising (I hope that I didn't drop an important macro): #define __USE_BSD 1 #define __unix__ 1 #define __linux 1 #define __unix 1 #define __linux__ 1 #define _POSIX_SOURCE 1 #define __STDC_HOSTED__ 1 #define __STDC_IEC_559__ 1 #define __gnu_linux__ 1 #define __USE_SVID 1 #define __USE_XOPEN2K 1 #define __USE_POSIX199506 1 #define _G_USING_THUNKS 1 #define __USE_XOPEN2K8 1 #define _BSD_SOURCE 1 #define unix 1 #define linux 1 #define __USE_POSIX 1 #define __USE_POSIX199309 1 #define __SSP__ 1 #define _SVID_SOURCE 1 #define _G_HAVE_SYS_CDEFS 1 #define __USE_POSIX_IMPLICITLY 1 Where do I find a detailed documentation of them - as to the mentioned Windows-specific macros above? Additionally I'd be interested in macros normally defined for other POSIX-compliant operating systems as *BSD etc.

• Deploy custom web service to sharepoint server(2007/2010)?

  - by leif

  According to MSDN, for deploying custom web service, we need to create *wsdl.aspx and *disco.aspx files, and put them with .asmx together under _vti_bin folder (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\isapi). And put the dll under bin folder of the root of sharepoint virtual directory. It works correctly for me. However, i also found that if i put .asmx file under the root virtual directory without creating those *wsdl.aspx and *disco.aspx files. It can work as well and much easier than the above way. So i'm wondering what's the potential issues in this way?

• VB.NET - ASP.NET - MS-Access - SQL Statement

  - by Brian

  I have a button which when pressed, sets the user's rights in the db. (If Administrator UserTypeID is set to '2' and if Customer it is set to '1'). However when I run the below code, everything remains the same. I think it's from the SQL statement but I;m not sure. Can anyone help please? Protected Sub btnSetUser_Click(sender As Object, e As System.EventArgs) Handles btnSetUser.Click Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\Brian\Documents\Visual Studio 2010\WebSites\WebSite3\db.mdb;") Dim cmd As OleDbCommand = New OleDbCommand("UPDATE [User] SET [UserTypeID] WHERE Username=?", conn) conn.Open() cmd.Parameters.AddWithValue("@Username", txtUser.Text) If ddUserType.SelectedItem.Text = "Administrator" Then cmd.Parameters.AddWithValue("@UserTypeID", "2") cmd.ExecuteNonQuery() lblSetUser.Text = txtUser.Text + "was set to Administrator."

End If conn.Close() End Sub End Class

• .odx Files in BizTalk 2009 (VS2008 IDE) Fail to open. "Unspecified Error"

  - by AllenG

  Okay, I'm not sure if this is an SO question, or a ServerFault question, but I figured I'd post here first. I have a BizTalk project which works like a champ for its original design. It's been deployed and it's working fine. Today, I went in to add some new fuctionality by modifying one of my orchestrations. When I attempted to open it, I got a message which simply stated: "The operation could not be completed. Unspecified error." I've closed the IDE and re-opened; I've restarted the machine; I've even allowed Microsoft Updates to run and restart the machine. Everything else opens just fine (.xsd files, .btms, etc.) so it appears only to be the orchestrations which are failing. Has anyone ever encountered a similar issue and resolved it (short of reinstalling BizTalk/VS, or blowing the orchs away and rebuilding)? Any help would be appreciated.

• ASP.NET site freezing up, showing odd text at top of the page while loading, on one server

  - by MGOwen

  I have various servers (dev, 2 x test, 2 x prod) running the same asp.net site. The test and prod servers are in load-balanced pairs. One of these pairs is exhibiting some kind of (super) slowdown or freezing every other page load or so. Sometimes a line of text appears at the very top of the page which looks something like: 00 OK Date: Thu, 01 Apr 2010 01:50:09 GMT Server: Microsoft-IIS/6.0 X-Powered_By: ASP.NET X-AspNet-Version:2.0.50727 Cache-Control:private Content-Type:text/html; charset=ut (the beginning and end are "cut off".) Has anyone seen anything like this before? Any idea what it means or what's causing it?

• Import received e-mails from Outlook to MSSQL database

  - by _simon_

  How can I automatically import some data from received e-mail from Outlook to MSSQL database? So, when I receive an e-mail (from a preset sender), Outlook should be able to run an external application with the subject and body as parameter. This application will then parse the body of the e-mail and send it to database. Is it possible to set this in 'Rules and alerts' in Outlook (I don't think so)? Or is it possible to do it with macros (an example would be nice). Or else...? I am using Microsoft Outlook 2007 (no Exchange Server), let's say, that incoming mail is from @gmail domain, the externam application would probably be a C# console application, database is SQL SERVER 2005.

• Adding to the browser user agent string?

  - by stwissel

  I have a plug-in that handles its own url schema (something like mystuf:// ). If a user clicks on such a link when the plug-in isn't installed (s)he gets an ugly error. So I extended my installer to write into the Registry (for Internet Explorer) and the user.js (for Firefox) to ADD a custom string to the user agent string. These additions survive a browser upgrade nicely (Microsoft uses this technique to indicate the presence of the dotNet Framework). Now I need to extend this to Apple Safari and Google Chrome on all supported platforms. To be clear: I'm not looking how to REPLACE the user agent string, but how to amend it with additional information. Any hint?

• Seeking References To MSVC 9.0's C++ Standards Compliance

  - by John Dibling

  I "know" (hopefully) that MSVC 9.0 Implements C++ 2003 (ISO/IEC 14882:2003). I am looking for a reference to this fact, and I am also looking for any research that has been done in to how compliant MSVC 9.0 is with that version of the Standard. I have searched for and not been able to find a specific reference from MicroSoft that actually says something to the effect that MSVC implements C++ 2003. Some of the out-of-date documentation says things like "this release achieves roughly 98% compliance" (when referring to MSVC .NET 2003's conformance to C++ 1997). But I want a link to a document from MS that says "MSVC 9.0 implements blah," and another link to an independent group that has tested the conformance of MSVC 9.0. Do you know of any such links?

• Hierarchical animations in DirectX and handling seperate animations on the same mesh?

  - by meds

  I have a hierarchical animated model in DirectX which loads and animates based on the following DirectX sample: http://msdn.microsoft.com/en-us/library/ee418677%28VS.85%29.aspx As good as the sample is it does not really go into some of the details of animation that I'd like. For example, if I have a mesh which has a running animation and a throwing animation as seperate animation sets how can I get the throwing animation to occur for bones above the hip and the walking animation to occur for bones underneath the hip? Also if I wanted to for example have the person lean left or right would I simply have to find the bone for the hip and multiplay a rotation matrix by its matrix? In this case I think the matrix is m_amxBoneOffsets?

• Why can't set cast an object from Excel interop?

  Trying to get a reference to the worksheets (using Excel interop): Excel.Application xl = new Excel.ApplicationClass(); Excel.Workbooks xlWorkBooks = xl.Workbooks; Excel.Workbook xlWorkBook = xlWorkBooks.Open(fileName, 0, false, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0); Excel.Worksheets xlWorkSheets = (Excel.Worksheets) xlWorkBook.Worksheets; // crashes The error is that it cannot cast it: Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Interop.Excel.Worksheets'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208B1-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

• Windows Mobile Development on MacBook Pro?

  - by Ted Nichols

  I am a frequent Windows Mobile application developer in need of a new development laptop. I am considering a MacBook or Macbook Pro running either Fusion from VMWare or Parallels Desktop. This will give me the option to port my applications to the iPhone depending on what MS does with WM 6.5 and 7. Has anybody tried doing Windows Mobile development using Microsoft Windows Mobile Device Center (or ActiveSync) and VS2008 on the MacBook Pro using one of these virtual machines? Does the device emulator work properly? What about debugging a Windows Mobile device over a USB cable? In general, do most USB drivers (non HID) designed for Windows work under these virtual machines? Thanks.

• Does MSDeploy support website and database upgrades?

  - by Samuel Jack

  I've just been reading about MSDeploy, the new website deployment tool from Microsoft. I'm developing an installer for a webapplication and a webservice to be used for our off-the-shelf product. I have a couple of questions that I couldn't find obvious answers to. Does MSDeploy have robust support for upgrading websites after the initial deployment? I can see MSDeploy has good support for the initial deployment of databases. But does it have support for upgrading schemas whilst preserving the current data? Links addressing these specific questions would be good.

• Problems with ASP.NET State Service version; state service is 1.1, website is 3.5

  - by Mick Byrne

  Hi there, I have a ASP.NET 3.5 website running on Windows Server 2003 and I'm using the ASP.NET State Service to manage sessions. It will appear to be working then I regularly get an error saying my code needs to have version 2.0 of the State Service running to work (I think that's what it said, I've temporarily switched back to storing sessions InProc). Refresh the page and the error goes away (for a bit, it's bound to come back). So I looked at the properties of the ASP.NET State Service in the Services interface and it's mapping to a .exe in the 1.1 framework folder: C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_state.exe There's a corresponding version in the 2.0 framework folder, but I don't know how to add it as a new service. I'm also not sure that adding the 2.0 version (and stopping and/or removing the 1.1 version) will solve the problem. Thanks in advance for any help anyone can provide. Mick

• ToolStripComboBox.SelectedItem change does not propagate to binding source

Now the dropdown list is populated as expected, but when I select and item in the list, the change is not propagated to the binding source. Any idea what I am doing wrong?
