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

Syntax

'Declaration
Public Overridable Sub AsyncDeriveParameters ( _
    command As String, _
    commandType As Integer, _
    commandTimeout As Integer, _
    asyncCommandEvents As DataAsyncCommandEvents _
)

public virtual void AsyncDeriveParameters(
    string command,
    int commandType,
    int commandTimeout,
    DataAsyncCommandEvents asyncCommandEvents
)

public:
virtual void AsyncDeriveParameters(
    String^ command, 
    int commandType, 
    int commandTimeout, 
    DataAsyncCommandEvents^ asyncCommandEvents
)

abstract AsyncDeriveParameters :

public function AsyncDeriveParameters(
    command : String, 
    commandType : int, 
    commandTimeout : int, 
    asyncCommandEvents : DataAsyncCommandEvents
)

Parameters

• command
  Type: System.String
  Command for which the parameters are derived.

• commandType
  Type: System.Int32
  Format of the command string.

• commandTimeout
  Type: System.Int32
  Amount of time, in seconds, before which the command times out.

• asyncCommandEvents
  Type: Microsoft.VisualStudio.Data.DataAsyncCommandEvents
  The object on which this method calls back as the command progresses.

Exceptions

Remarks

This method performs the same operation as the DeriveParameters method, but in an asynchronous manner.

If the value of the commandTimeout parameter is 0, there is no timeout (or, timeout is infinite); if the value is -1, the timeout period is that set by the data provider.
