SalBoolean DataSourceCreateWindow( SalNumber nWhat, SalString sWindowName )
Applications and the framework call the DataSourceCreateWindow method to initialize data transfer and create a window.
Name | Description |
---|---|
SalNumber nWhat | Standard method parameter. Possible values are Const.METHOD_Inquire, Const.METHOD_Execute. |
SalString sWindowName | Name of window to create. |
When nWhat = Const.METHOD_Inquire: the return value is TRUE if the window is
included in the application, and the corresponding data source is available.
When nWhat =
Const.METHOD_Execute: the return value is TRUE if the window is
successfully created, FALSE otherwise.
Before creating the window, DataSourceCreateWindow calls DataSourcePrepareKeyTransfer to initialize data transfer.
