SetFormScriptLimits

Forms, JavaScript safety

Description

Configures independent limits for form-script source length, interpreter operations, parser nesting, string values and object-property accesses

Function TPDFlib.SetFormScriptLimits(MaxScriptLength, MaxOperations, MaxNestingDepth, MaxStringLength, MaxPropertyAccesses: Integer): Integer;

MaxScriptLength	Source-character limit from 1,024 through 1,048,576
MaxOperations	Interpreter-operation limit from 64 through 1,000,000
MaxNestingDepth	Parser nesting limit from 8 through 256
MaxStringLength	Per-string character limit from 1,024 through 16,777,216
MaxPropertyAccesses	Object-property access limit from 16 through 1,000,000

Returns 1 when all limits are accepted, or 0 with LastErrorCode 708 when any value is outside its range

The defaults are 65,536 source characters, 4,096 operations, 64 nesting levels, 1,048,576 string characters and 4,096 property accesses

The same limits apply to direct field-event execution, recalculation and dependency analysis
