Visual Basic 2008 + SQL Server 2008 R2

alexandruvint — Sat, 13 Nov 2010 07:42:14 GMT

Buna dimineata,
Am realizat o aplicatie in VB2008 iar baza de date in SQL Server 2008 R2. As vrea sa instalez aplicatia pe un alt calculator. Stiu ca trebuie sa includ in setup atat fisierele din Release, cat si baza de date. Care ar fi pasii? Ma gandesc ca trebuie in primul rand sa se realizeze o conexiune ,la prima rulare a programului, intre baza de date si aplicatie.

da = New SqlDataAdapter(sqlfltr, cs)
da.Fill(ds, sqlfltr)

Eroare New Database Diagram ...

bustiuci — Sun, 02 Dec 2007 10:38:37 GMT

Pe un SQL Server 2005 Standard cu Visual Studio 2005 Pro si 2003 cand vreau sa creez sau sa vizualizez un "Database Diagram" in MS SQL Server Management Studio am eroarea descrisa mai jos. Detaliile sunt din dialogul cu mesajul "Unspecified error".

===================================

Unspecified error
(MS Visual Database Tools)

------------------------------
Program Location:

   at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo)
   at Microsoft.SqlServer.Management.UI.VSIntegration.Editors.VirtualProject.Microsoft.SqlServer.Management.UI.VSIntegration.Editors.ISqlVirtualProject.CreateDesigner(Urn origUrn, DocumentType editorType, DocumentOptions aeOptions, IManagedConnection con)
   at Microsoft.SqlServer.Management.UI.VSIntegration.Editors.ISqlVirtualProject.CreateDesigner(Urn origUrn, DocumentType editorType, DocumentOptions aeOptions, IManagedConnection con)
   at Microsoft.SqlServer.Management.UI.VSIntegration.Editors.VsDocumentMenuItem.CreateDesignerWindow(IManagedConnection mc, DocumentOptions options)

In Visual studio la Server Tools cand vreau sa adaug o Diagrama noua acelasi mesaj imi da "Unspecified Error".

Din detaliile de mai sus pare sa fie o problema cu o componenta COM parte din MS SQL Server Management Studio.

Stie cineva cum se rezolva aceasta problema.

Pe undeva prin internet am gasit sugestia sa fac Remove Program apoi sa Instalez, dar la ce? La MS SQL Server 2005 tot sau doar Client Tools sau tot, ori la Visual Studio 2005.

Multumesc.

Microsoft® Visual Studio® 2005 Team Edition for Database Professionals Power Tools

MrSmersh — Sat, 18 Aug 2007 09:59:17 GMT

Au aparut, download aici.
Cam ce cuprind (conforma download manifest):
This release includes 5 new refactoring types, a new dependency viewer, additional data generators and editors, 2 new MSBuild tasks for Schema and Data Compare as well as the introduction of the TSQL Static Code Analysis feature

TSQL Static Code Analysis
• Static Code Analysis - A precursor to the functionality that will be in future versions of VSTS that will allow you to perform Static Code Analysis on T-SQL code.

Refactoring
• “Move Schema” Refactoring - Allows a user to right click on an object and move it to a different but existing schema
• SP Rename Generation - Generate a new script that will contain sp_renames for all rename refactored objects that the user can then execute.
• Wildcard Expansion - Automatically expand the wildcard in a select to the appropriate columns.
• Fully-Qualified Name Support - Automatically inject fully-qualified names when absent in a script
• Refactoring extended to Dataset - Refactor into strongly typed dataset definitions

MSBuild Tasks
• Data / Schema Compare Build Tasks - MSBuild tasks that can generate scripts as if the user had run the Data / Schema compare UI

Schema View
• API Access to Schema View - Insert / Update / Delete to schema View and list schema objects and their associated files

Dependency Tool Window
• Dependency Tree - Show the dependencies ( incoming / outgoing ) for selected schema objects in a new tool window

Miscellaneous Tools
• Script Preprocessor - Expand SQLCMD variables and include files and command line version (sqlspp.exe) & an MSBuild version ( wraps the command line version )

.NET Framework 3.0 si SQL Server 2005 SP2

adrian_trif — Mon, 11 Dec 2006 12:03:17 GMT

Exista vreun lucru nou pentru tandemul NET Framework 3.0/SQL Server 2005 SP2 ?

Adica in afara de chestiile pentru Vista si Visual Studio aduce .NET Framework 3.0 ceva bun (sau macar nou) pentru SQL ?
