Connecting Visual Basic To SQL Server Using VB Data Source Configuration Wizard?

Dec 29, 2007

I am a brand new user of MS Visual Basic 2005 Express and MS SQL Server 2005 Express.  I have familiarized myself with both programs but have one extremely frustrating problem.  Once I open SQL Server, I can not establish a database connection from Visual Basic using the Visual Basic Data Source Configuration Wizard (even if I close SQL Server).  If I reboot and open Visual Basic first, I can then connect using the Visual Basic Data Source Configuration Wizard.  But then I can not switch to SQL Server and open the database (even if I close Visual Basic).  Again, I must reboot to open the database in SQL Server.I suspect there is a setting somewhere that needs to be changed, but I can not find it?

.net - Which Version Of Visual Studio 2010 Contains Visual Basic SharePoint Templates

Aug 5, 2011

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.

At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates

Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

How To Call A C++ Dll File From Visual Basic 2010

Mar 9, 2012

I'm using Microsoft Visual Studio 2010 Express: the C++ and VB versions.

There is some VB code that forms the body of a program, and all the GUI.There is also some C++ code that does some fast processing (lots of loops).

I am trying to call the C++ code, compiled as a dll, using:

Private Declare Sub CalcGraph Lib "Model.dll" ()

And at the moment keep getting the error: Unhandled exception has occurred in your application. Unable to find an entry point named 'CalcGraph' in DLL 'Model.dll'I'm fairly new to programming, so please be patient with me That said, I'm prepared to do the leg-work, and have already spent quite a while reading around on this and other sites. Nothing seems to match quite well enough to help me understand what's going wrong.
