Data updating problems in Multi-Form situation
In an application, multiple forms would be used from one work station. The forms would refer to the same table, opened under default data session in data environment.
While there is no problem with the data structure and the data integrity, updates in one form would not instanteously reflect in the other form(s). Is there a general guideline for handling such a process?
Additionaly, when data field rules are violated (i.e., a new data refering to a new master domain record) of in performing updating process in a form (say, a transacting process), I would attempt to bring in the relevant form (say, a maintenance process) to augment the data domain, data crash would also result. Which form method I could use to control the concurrent form switching while accessing the same set of closely knitted data files?
I am new to the concurrent form concept in VFP and the foregoing problems have been a big headache in our design. Any suggestion would be appreciated.
