GetRef to capture methods?
I've just discovered VBScript's GetRef function, which gets a开发者_StackOverflow社区 reference to the function named by its argument. Is there any way to get a reference to a method in this way? I have a hunch that VBScript doesn't offer the sophistication of binding needed to do so, but it would sure be nice.
No, GetRef
doesn't support class methods.
There is a workaround for this, see my answer here
Here the full sample
Const forReading = 1, forWriting = 2, forAppending = 8, CreateFile = True
Set my_obj = CreateObject("Scripting.FileSystemObject").OpenTextFile("c:\temp\test.txt", forWriting, CreateFile)
Function my_function(my_obj, method, text)
command = "my_obj." & method & " """ & text & """"
ExecuteGlobal command
End Function
'make a reference to our function
Set proc = GetRef("my_function")
'and call it with parameters, the first being the method invoked
Call proc(my_obj, "WriteLine", "testing")
'cleanup'
my_obj.Close
Set my_obj = Nothing
