• ::LookupAccountSid API Extremely Slow When Targetting x64 Platform (Windows 7)

  - by Chris

  During our application startup, we are making a call to ::LookupAccountSid(). When I build targetting the x86 architecture, this call is nearly instantaneous. However, when I target x64 (debug or release), the call generally takes over 40s to complete. Since this is occurring during application startup, the result is fairly unpleasant as it will appear to the user that the application is not launching. I am running Windows 7 Professional 64-bit on a Dell Studio XPS 16 (Intel Core i7 Q 720). Our application is a native Windows application written in C++. My compiler options (CCOPTS) and linker options (LINKOPTS) are as follows: CCOPTS = "/nologo /Gz /W3 /EHs /c /DWIN32 /D_MBCS /Ob1 /vmg /vmv /Zi /MD /DNDEBUG /DDV_BUILD_DLL /DIV_BUILD_DLL /DDVASSERT_EXCEPTION /Zc:wchar_t-" LINKOPTS = "/manifest:no /nologo /machine:X64 kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib /DEBUG /subsystem:windows /DLL" Any help would be greatly appreciated :D Thanks, --Chris

• ASP.Net Web Site Project - Errors Not Caught at Compile time

  - by 5arx

  For the first time in my career, I'm working on an ASP.Net (v3.5) project that has been set up as a Visual Studio 2008/10 Web Site Project. I'm not keen on this way of working this way for various reasons but for the moment and until such time as the company sees the virtue in working in an environment with namespaces, designer and project files etc., I have to continue with the existing codebase. I've run into some odd issues since I began this but perhaps the oddest one of all is that althought VS lets me build the code, it doesn't reliably pick up compilation errors so these are not noticed until runtime. I know the website model allows dynamic/hot compilation when a request is made for a specific but I can't see why it wouldn't do this when I manually (F5) build/rebuild the project. Its immensely annoying as you can imagine and I can't find a workaround. Could any StackOverflow person help with suome suggestions to make things better?

• Run Exchange Management Shell cmdlets from Visual Basic/C#/.NET app

  - by nowarninglabel

  Goal: Provide a web service using Visual Basic or C# or .NET that interacts with the Exchange Management Shell, sending it commands to run cmdlets, and return the results as XML. (Note that we could use any lanaguage to write the service, but since it is a Windows Box and we have Visual Studio 2008, it seemed like easiest solution would be just use it to create a VB/.NET web service. Indeed, it was quite easy to do so, just point and click.) Problem: How to run an Exchange Management Shell cmdlet from the web service, e.g, Get-DistributionGroupMember "Live Presidents" Seems that we should be able to create a PowerShell script that runs the cmdlet, and be able to call that from the command line, and thus just call it from within the program. Does this sound correct? If so how would I go about this? Thanks. Answer can be language agnostic, but Visual Basic would probably be best since that is what I loaded the test web service up in.

• Online product demo environment for Windows applications

  - by Stefanos Tses

  I'm looking for a way to allow potential customers to try my application before they buy it. The product is a windows forms application that requires an SQL Server database to operate. Although I have a functional demo that the customer can install on their network, I want to make it easier for them by have them "play" with it at my environment. I remember Microsoft had (has?) something similar. I was testing Visual Studio a few years ago in a virtual environment where I was connecting to a server at Microsoft. Any suggestions? Thanks.

• C# Windows Forms Print Dialog box click OK twice to respond

  - by sbartlett007

  I'm using Visual Studio 2008, .net Framework 3.5 for a Windows forms client-server app that I'm working on. There is a weird bug when I run the program and try to print. The print dialog box opens, but I have to click the OK button twice for it to work. After the second click it works fine, no errors. When I put a breakpoint on: if (result == DialogResult.OK) , the breakpoint doesn't trigger until the second click. Here is the code: private void tbPrint_Click(object sender, EventArgs e) { try { printDialog1.Document = pDoc; DialogResult result = printDialog1.ShowDialog(); if (result == DialogResult.OK) { pDoc.PrinterSettings.PrinterName = printDialog1.PrinterSettings.PrinterName; pDoc.Print(); } ... This is driving me crazy, and I can't see anything else that would interfere with it.

• Automatically generate buddy classes from model in C#

  - by JohnnyO

  I use Linq to Sql (although this is equally applicable in Entity Framework) for my models, and I'm finding myself creating buddy classes for my models all the time. I find this time consuming and repetitive. Is there an easy way to automatically generate these buddy classes based on the models? Perhaps a visual studio macro? An example of a buddy class that I'd like to create: [MetadataType(typeof(PersonMetadata))] public partial class Person { } public class PersonMetadata { public object Id { get; set; } public object FirstName { get; set; } } Thanks in advance.

Application pool is using NetworkService account which has access to SQL Server. I can access the configuration databases through SQL Management Studio. SQL server is on the same machine. Any help, suggestions on how to solve the problem? I am very new to SharePoint.

• Using Visual sudio .ncb file for reflection.

  - by Rushi

  I am developing visual game level editor in c++. For this I want reflection(RTTI) mechanism to know class attributes at runtime. I am currently using PDB files for this.But using PDB I couldn't retrieve actual code line for extra information in commented format which is given for that attribute. Visual studio uses NCB files for intelligence. So will it be better idea to use NCB instead PDB? If yes,How to retrieve information from NCB files? Is there any SDK like DIA SDK?

• ReturnUrl = Default.aspx for MVC?

  - by Cynthia

  I'm trying to secure my entire MVC site, so before the Home controller, I added an [Authorize] attribute. Now if you run it from Visual Studio or navigate using the root URL (e.g. http://localhost:2897) it does redirect to the login page, as expected. However the URL in the address bar after redirection looks like this: http://localhost:2897/Account/LogOn?ReturnUrl=%2fdefault.aspx%3f I haven't tested this out, seeing as I have not implemented my authentication code. However, this looks like a big problem to me, since I do not have a default.aspx in my project! My authentication tag in the web.config looks like this: <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" defaultUrl="~/Home/Index" timeout="2880"/> </authentication> Why doesn't it pick up this route as the default ReturnUrl instead of default.aspx?

• 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.

• Any way to rename a deployed ClickOnce app?

  - by tobinibot

  My company has a ClickOnce that has been in use with our customers for about a year now. We're going through a re-branding, and want to change the name of the application. However, just changing all of the normal name options in Visual Studio, and then building a new deploy obviously changes the manifests that the existing app is looking for, so essentially any installed apps never see the new updates. I've tried messing around with the .application file, but haven't been able to get anything to work yet. Is there anyway to rename a deployed ClickOnce app, or do we have to get people to just install the new app?

• Source Insight: Show me Enum Values

  - by JXG

  I'm programming in C and using Source Insight. I have an enum type with a lot of constants (like 100). I have debug prints that print out variable values, but they (of course) print out as integers. What I'd like to do is click on the name of an enum constant, and see its numeric value displayed somewhere. (I've seen this done in a Visual Studio plugin, so it must be possible.) That is, assume I have enum colors { ORANGE, PURPLE, PINK }; I want to click on (or select, or something) PURPLE and see the value 1 somewhere visible (ideally, the symbol window or context window, but I'm not particular). Is there an easy way to do this in Source Insight? Is there a difficult way, at least (such as writing a macro)?

• MySQL, C++: Retrieving auto-increment ID

  - by Thomas Matthews

  I have a table with an auto-incrementing ID. After inserting a new row, I would like to retrieve the new ID. I found an article that used the MySQL function LAST_INSERT_ID(). The article says to create a new query and submit it. I'm using MySQL Connector C++, Windows XP and Vista, and Visual Studio 9. Here are my questions: Is there an API, for the connector, that will fetch the ID out of the record? Does the result set, after an insert/append, contain the new ID? The LAST_INSERT_ID is MySQL specific. Is there an SQL standard method for obtaining the new ID?

  Hi all, I'm using Visual Studio .NET 2003, and I'm trying to convert a program written in purely ANSI characters to be independent of Unicode/Multi-byte characters. The program has a callback function of pcap_loop, called "got_packet".

• Why does my Excel add-in only half work?

  - by Dan Crowther

  I've created an Excel add-in using Visual Studio 2008. It has a ribbon, a bunch of panes and code that adds sheets and ranges and gets information scraped from a web page. When I run it on my dev PC it works perfectly. I used the Publish command to publich it and installed on a Windows XP virtual PC. The installation seemed fine and when I open Excel I see my ribbon. If I click a button that shows a pane, up pops the pane. If I enter some details into the pane that should create a range and populate it with data from a web page, the range is created but the web page is not visited (I have tested that I have connectivity). One of my buttons adds a hidden worksheet and another displays or hides that sheet. One of these buttons is not working. I've tried everything I can think of. I'm wondering if there are any permissions or trust issues I need to deal with?

• Full text searching in SQL Server 2008 Express Advanced

  - by Iain Macleod

  Hi, I have recently installed SQL Server 2008 Express Edition with Advanced Services on XP Pro but am having trouble getting full text searching to work with an restored database. The database was originally created in SQL Server 2005. When I call a stored proc that uses the full text index then I get the following error: Full-Text Search is not installed, or a full-text component cannot be loaded. This is my db version: Microsoft SQL Server 2008 (RTM) - 10.0.1600.22 (Intel X86) Jul 9 2008 14:43:34 Copyright (c) 1988-2008 Microsoft Corporation Express Edition with Advanced Services on Windows NT 5.1 (Build 2600: Service Pack 3) When I run: SELECT DATABASEPROPERTY('DBNAME','ISFULLTEXTENABLED') I get: 1 Also, when I look in the advanced properties for the db server in Management Studio I see both the "Default Full-Text Language" and "Full-Text Upgrade Option" properties. However, when I go to SQL Server Configuration Manager I don't see the "MSSQLFDLauncher" service. Does anyone know how to get this working? Cheers, Iain

• Tortoise SVN Icon Overlays Displaying Everywhere...Why?

  - by jwalkerjr

  Update: So, this turns out to have nothing to do with Tortoise SVN. I use Mozy.com for off-site backups and their new version includes these icon overlays. They can be disabled via the config options...or see here http://forum.pcmech.com/showthread.php?p=1385433. Thanks @OS for the answer. Been using Tortoise SVN for some time on my Vista box. Within the last few days (and after recently upgrading to 1.5.4) the icon overlays are displaying on all files. My exclude path is: * My include paths are: C:\Users\jw\Documents\Visual Studio 2008\Projects\SVNProjects* C:\Users\jw\Documents\VB Projects\SVNProjects* I haven't touched those settings in months. Any ideas? Help. Thanks.

• Is it good to use .settings for storing controls text data?

  - by Zenya

  In my WinForms applications I often put the controls text data (form title, labels texts, button captions, etc.) into a .settings (feature automatically generated by Visual Studio - based on the ApplicationSettingsBase class). In particular, Add a form or a control. In Solution Explorer add a new string item into the application scope of the settings file. Bind the control text property with the corresponding item of the settings file (through the property binding). Good point of this is that all my text data is collected in one place and easy to check and edit. Also it is convenient when I want to use the same text for several controls. However, I haven't heard that somebody uses the .settings such way. In tutorials for creating multilingual applications, for example, it is recommended to enter texts directly into the control property. So, is it good practice to use .settings for storing controls text data? Brief conclusion from the answers: Storing controls text data in the .settings is not common practice.

• Best Template Engine for ASP.NET MVC

  - by OnesimusUnbound

  I am exploring ASP.NET MVC and I wanted to add jQuery to make the site interactive. I used StringTemplate, ported to .Net, as my template engine to generate html and to send JSON. However, when I view the page, I could not see it. After debugging, I've realized that the $ is used by the StringTemplate to access property, etc and jQuery uses it too to manipulate the DOM. Gee, I've looked on other template engines and most of them uses the dollar sign :(. Any alternative template engine for ASP.Net MVC? I wanted to retain jQuery because MSFT announced that it will used in the Visual Studio (2008?) Thanks in Advance :)

• sql server 2005 reporting services-- how to use multiple datasets in report

  - by larryq

  Hi everyone, I'm new to SQL Server reporting services, and am trying to decipher an existing report. It's nothing too bad, but I notice it does have two report datasets defined. (They are generated via separate stored procedures) I'm trying to figure out where and how the report datasets are linked together so the Fields collection has both sets of columns available and the report has a single rowset to traverse. Is there a section in the report layout where a joining of datasets is defined? I'm using Visual Studio 2005 to design and preview the report fwiw. Thanks for your help!
