Accessing variable inside Vbstart-VBEnd block

[aks]

Hi,

let>res=This is a test message
VBSTART
dim res
msg=res
MsgBox(msg)
VBEND

What is missing in the above code snippet? Or the only way to link vbscript and macro is to use function and sub commands of vbscript? Meaning:

let>res=This is a test message
VBSTART
Sub DisplayMessage (msg)
MsgBox msg
End Sub
VBEND
VBRun>DisplayMessage,res

??

You can use VBEval to evaluate a VBScript expression. A VBScript expression could be just a variable:

Code: Select all

VBSTART
  dim res
  res = "fred"
VBEND

VBEval>res,myRes
MessageModal>myRes

The VBEval statement is evaluating the value of res which of course is "fred".

Often we need to use both methods. E.g. you may VBEval a VBScript function which creates an array or modifies a set of global VBScript variables which you later might want to evaluate in MacroScript using VBEval.

Hi Marcus,

Same way how can i access variable set using macro inside the vb block?
if i do:
let>msg=hello world
vbstart
msgBox msg
vbend

If i execute this code vb msg box is empty. I have also tried declaring the msg variable global inside the vbblock using dim. Still i dont get the message.

In this case you must pass the value to a VBScript sub/function. The VBScript must appear before the VBRun/VBEval:

Code: Select all

VBSTART
  Sub DoSomething(x)
     MsgBox x
  End Sub
VBEND

VBRun>DoSomething,Hello World
