[BUG/PRB.] VFP 9.0 FIX - THE MAXIMUM NUMBER OF THE RETURN VALUE OF THE VALID EVENT
December 2024
--------------------------------------------------------------------------------------------
CCB
1. BUG:
In vfp9 (and vfp6, vfp7, vfp8), sometimes the Valid event returns a BIG random number, VFP will enter an infinite loop.
In VFP Advanced, if the absolute value of the return value of the Valid event > the maximum number of the return value of the Valid event,
VFP will reset the return value of the Valid event to 1, the next control will get the focus.
The bug occurs in the Valid event for the following controls:
CheckBox control
ComboBox control
CommandButton control
CommandGroup control
EditBox control
Grid control
ListBox control
OptionButton control
OptionGroup control
Spinner control
TextBox control
2. CAUSE:
There are some BUGs in the following code.
3. RESOLUTION:
We can write some code to fix the BUG.
