Namespace:  Microsoft.VisualStudio.Data.Core
Assembly:  Microsoft.VisualStudio.Data.Core (in Microsoft.VisualStudio.Data.Core.dll)

Syntax

'Declaration
ReadOnly Property DefaultProvider As Guid
'Usage
Dim instance As IVsDataSource 
Dim value As Guid 

value = instance.DefaultProvider
Guid DefaultProvider { get; }
property Guid DefaultProvider {
    Guid get ();
}
function get DefaultProvider () : Guid

Property Value

Type: System.Guid
The default provider that supports the DDEX data source.

Remarks

Each DDEX data source is represented by one or more supporting DDEX providers. In most cases, there is a default provider associated with each data source, typically produced by the same company that produces the data source technology. For example, the Microsoft SQL Server data source has the default provider .NET Framework Data Provider for SQL Server. Both the data source technology and the default provider are produced by Microsoft.

This property determines the default provider by calling the GetProperty method, passing in the parameter DefaultProvider, to retrieve a string representation of the default provider GUID. If this succeeds, the property attempts to convert the string into a Guid value. If this succeeds, the property verifies that the GUID matches one of the data source’s supporting providers. If any one of these steps fail, the property returns an empty GUID.
