Abandoning error rows
In some cases, you may want to enable users or your application
to completely discard one or more error rows from the error DataWindow
control. This can be useful for dealing with error rows that it
is not desirable to repair.
Table 17-4 shows
some techniques you can use for abandoning such error rows.
|
If |
Use |
|---|---|
|
All error rows in the error DataWindow |
The Reset function |
|
One or more particular error rows in |
The RowsDiscard function |
For more information on coding these functions,
see the PowerScript Reference.
Example
In the following example, users can choose to abandon all
error rows in the dw_pipe_errors DataWindow
control.
Providing a CommandButton
When painting the w_sales_extract window, include
a CommandButton control named cb_forgofixes.
Write code in a few of the application’s scripts to enable
this CommandButton when dw_pipe_errors contains
error rows and to disable it when no error rows appear.
Calling the Reset function
Next write a script for the Clicked event of cb_forgofixes.
This script calls the Reset function:
|
1 |
dw_pipe_errors.Reset() |
Together, these features let a user of the application click
the cb_forgofixes CommandButton to
discard all error rows from dw_pipe_errors.
