• My code works in Debug mode, but not in Release mode.

  - by Nima

  Hi, I have a code in Visual Studio 2008 in C++ that works with files just by fopen and fclose. Everything works perfect in Debug mode. and I have tested with several datasets. But it doesn't work in release mode. It crashes all the time. I have turned off all the optimizations, also there is no dependency to anything(in the linker), and also I have set these: Optimization: Disabled(/Od) Keep Unreferenced Data. Do Not Remove Redundant Optimize for Windows98: NO I still keep wondering how it should not work under these circumstances. What else should I turn off to let it works as in debug mode? I think if it works in release mode but not in debug mode, it might be a coding fault but the other way looks weird. isn't it? I appreciate any help. --Nima

• Stopping Windows Mobile 6.5 tab reordering

  - by PaulH

  I have a C++ Visual Studio 2008 Windows Mobile 6.5 application that uses a tab control. I've noticed that depending on how careful you are with the stylus, when using the tab control you can accidentally re-order the tabs. It's difficult to do deliberately, but it's very easy to do when you're not trying. I assume this is a new "feature" of Windows Mobile 6.5 as it doesn't happen in Windows Mobile 6.1 with the same code. Is there a window style or something I can set that will lock the tab order such that people don't accidentally re-arrange them? Also, is there an MSDN page that describes this behavior and how it is supposed to work? I've looked, but have come up empty. Thanks, PaulH

• 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?

• Why is SVN better than VSS? [closed]

  - by tsilb

  I've heard soooo many people complain about VSS, and noooo people complaining about SVN. We use SVN on my work project. It's slow, regularly freezes up my IDE, and has wonky behavior like looking for a database server every time I right-click the Solution node in my Solution Explorer. When I used VSS, everything worked beautifully, except for access restrictions which I of course blame on the people who control access. VSS is built by Microsoft and thus has great integration with Visual Studio. SVN is written by pretty much anybody with some free time (right?) and thus kinda works most of the time... And I honestly get the impression they had a dozen different directions in the design instead of one. So why do I keep hearing that SVN is better than VSS?

• Is WPF a good choice for developing line of business user interfaces?

  - by Randy Minder

  We're debating whether our future Windows UI development should be WinForms or WPF. How have some of you made this decision? Most of our applications are LOB applications, and I'm not sure I see a clear and overwhelming benefit to WPF for these types of applications. However, my knowledge of WPF is limited. I'm also a little concerned that WPF will be in vogue for another couple years and then Microsoft will get tired of it and push something else on us. I guess one argument against this is the fact that Visual Studio 2010 is a WPF application. Thanks.

• How do I create a class associated with a windows form in C#?

  - by xarzu

  Now that C++ development has become second nature to me, do I have to start from scratch with C#? Since the beginning of Visual Studio, there has been easy way to describe the shape of a Dialog (now called a Form) in the resource file and then use a wizard to create the corresponding C++ code. I kind of remember that in MFC it was pretty much a no-brainer to create a custom dialog with all the components you want and then all the associated code. If I have a C# app that has many forms that I want to bring to the screen based on the user's menu selections, how do I create a class associated with a windows form?

• 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

• 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?

• 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.

• can't publish my asp.net project?

  - by Sulaiman

  dears, when try to publish my mroject I get this error: Error 3 Task failed because "AL.exe" was not found, or the correct Microsoft Windows SDK is not installed. The task is looking for "AL.exe" in the "bin" subdirectory beneath the location specified in the InstallationFolder value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v6.0A. You may be able to solve the problem by doing one of the following: 1) Install the Microsoft Windows SDK for Windows Server 2008 and .NET Framework 3.5. 2) Install Visual Studio 2008. 3) Manually set the above registry key to the correct location. 4) Pass the correct location into the "ToolPath" parameter of the task.

• 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 :)

• Web service reference location?

  - by Damien Dennehy

  I have a Visual Studio 2008 solution that's currently consisting of three projects: A DataFactory project for Business Logic/Data Access. A Web project consisting of the actual user interface, pages, controls, etc. A Web.Core project consisting of utility classes, etc. The application requires consuming a web service. Normally I'd add the service reference to the Web project, but I'm not sure if this is best practice or not. The following options are open to me: Add the reference to the Web project. Add the reference to the Web.Core project, and create a wrapper method that Web will call to consume the web service. Add a new project called Web.Services, and copy step 2. This project is expected to increase in size so I'm open to any suggestions.

• Securing against dynamic linking in .NET

  - by Henri

  I want to deploy an application with a license attached. However, I want to prevent that my dll can be easily referenced in visual studio. What are the usual ways of doing this? I was thinking about ngen-ing the application to prevent this, however, then the code becomes architecture dependent. Im not targetting any other architecture/platform besides windows, however, ngen-ing the application after making a release build seems like a workaround to me. Are there any other techniques to achieve this?

• Pervasive SQL german Umlauts Problem

  - by cordellcp3

  Hi there, I'm using the Pervasive SQL - ADO.NET 3.5 DataProvider for retrieving data out of the PSQL DB and I've noticed that the german umlauts (äöüÄÖÜ etc.) are not represented correctly in the PSQLDataReader, but in the Pervasive Control Center (similar to the sql management studio) the umlauts are all correct. Is there anything similar to the TSQL "SET LANGUAGE"-command? I havn't found something like that for Pervasive SQL. Googling this issue wasn't successful at all, too. Although I did find some tips with a file called upper.alt or collate.cfg, but don't know how to use this files and I coudn`t find them in my installation. (I'm totally new to Pervasive...) I hope that someone on here could help me with that. Thanks in advance

The program has a callback function of pcap_loop, called "got_packet".

• Imitate database in C

  - by Mohit Deshpande

  I am fairly new to C. (I have good knowledge of C# [Visual Studio] and Java [Eclipse]) I want to make a program that stores information. My first instinct was to use a database like SQL Server. But I don't think that it is compatible with C. So now I have two options: Create a struct (also typedef) containing the data types. Find a way to integrate SQLite through a C header file Which option do you think is best? Or do you have another option? I am kind of leaning toward making a struct with a typedef, but could be pursuaded to change my mind.

• Create list in existing site collection from a feature

  - by keysersoze

  I have created a feature, a publishing site, in Visual Studio to MOSS - this feature contains a masterpage, some page-templates, some site columns (grouped to match each page-template) and som custom list templates etc. I have also created a site collection, some sites and pages based on my feature. Now I have upgraded the code in my feature - I wanted a ListInstance to be created based on my custom list template. When I have upgraded my SharePoint (using WSPBuilder), the ListInstance and default data are visible if I create a new site collection, but existing site collection does not get the ListInstance and data. Is there anything I can do to update existing site collections to contain the ListInstance when upgrading?

• Why can't I publish MVC project

  - by Vnuk

  I'm having problems publishing my MVC project. When I do publish and upload everything to web server I get this: [InvalidOperationException: The view 'Index' or its master could not be found. The following locations were searched: ~/Views/Home/Index.aspx ~/Views/Home/Index.ascx ~/Views/Shared/Index.aspx ~/Views/Shared/Index.ascx] Weird thing is that Index.aspx exists in ~/Views/Home/, but IIS cannot find it there. If I copy entire project to web server and let asp.net compile it on the fly it works like a charm. My routing code: routes.MapRoute( _ "Default", _ "{controller}/{action}/{id}", _ New With {.controller = "Home", .action = "Index", .id = ""} _ ) routes.MapRoute("Root", "", New With {.controller = "Home", .action = "Index", .id =""}) I'm using IIS7 on Windows 2008 Web server. ASP.NET MVC 1.0, Visual Studio 2008. I've tried it local with IIS7 on Windows 7 - same error.

• 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.
