Recently due to the needs of the project, we have begun to do the development of the crystal report, encounter a problem, summarized as follows:
1, the problem of the field change: one report has been designed with the PUSH mode, all of which are all done, the report can also be displayed normally, but now the database has two fields of the fields, and then run now The report will not find that two fields, the field name is changed, and it is not found, and the other problem is found, that is, the Dataset has been updated, and adds a table, how to refresh it in the data expert. Come out, I am mad at me. Finally, after the 9CBS forum, through the heroic point, the method is solved, the method is as follows:
Open DataSet, regenerate the dataset, then go to the crystal report, run the verify database command, will prompt the change, then pop up a window, list the field of UNMAP, point in the window, then map I sure to return to the crystal report, save it, if I generate DataSet, I can preview DataSet first after the DataSet is generated.
