Hi All ,
This is my first email to group......however i havenot read the complete mail.
just scanned....
Bu what I & my friend Anish can say is ..................
If you dont want to display all the values of a specific base enum
in
certain forms, is it necessary to delete some values from a BaseEnum at
runtime? Instead of deleting we can hide the values from the user.
1 Hiding the value from the user on a specific form
Control which present the enumtype should have AutoDeclaration (yes)
Try this piece of code
Control_name.delete(Name of the element);
If we really want to delete the values of a baseenum on run time Use the
class SysDictEnum
2 Deleting the enum value on Run time (dynamically)
SysDictEnum = new SysDictEnum(enum_Id); //initialization
Sysdictenum.treeNode().AOTfindChild("Name of the
element").AOTdelete(); //deleting the element from the Enum
SysDictEnum.treeNode().AOTcompile(1); //compile
SysDictEnum.treeNode().AOTsave(); //Saving the baseenum

this disscusion already old, but does anyone already found the
solution yet? 'cause this's also my problem right now.. :)
Daniel's code seems fine to me, b'cause when I debug it, the final
result is the value of the original enum, not the deleted one.
But the overwrite method "Enter" which delete the unwanted enum
produce an unbalance program, after I select the enum combo, the
form refresh all the time..
thanks,
