- Attributes
Methods
| Name | Description |
|---|---|
| CancelAsync(Object) |
When implemented by a class, cancels the asynchronous call, returning immediately. |
| DeriveParametersAsync(String, DataCommandType, Int32, Object) |
When implemented by a class, derives, in an asynchronous manner, a set of parameters for use with a specified command. |
| DeriveSchemaAsync(String, DataCommandType, IVsDataParameter[], Int32, Object) |
When implemented by a class, derives, in an asynchronous manner, the schema of the specified command. |
| ExecuteAsync(String, DataCommandType, IVsDataParameter[], Int32, Object) |
When implemented by a class, executes a command in an asynchronous manner. |
| ExecuteWithoutResultsAsync(String, DataCommandType, IVsDataParameter[], Int32, Object) |
Executes, in an asynchronous manner, a command that does not return any results beyond an integer value indicating status. |
| PrepareAsync(String, DataCommandType, IVsDataParameter[], Int32, Object) |
When implemented by a class, prepares, in an asynchronous manner, the specified command to be executed against the data source; the command can then be executed multiple times, with varying parameters. |
Events
