有关Environment Variable被赋值
If we try to use Set to assign an object to the Environment Variable, 'Type mismatch' exception is raised.
1. use a string definition of the object and then convert it to an object
2. assign the object to the variable without using the Set
Method 1
Environment("BrowserObj") = "Browser(""creationtime:=0"")"
Dim objBrowser
Excute "set objBrowser = "& Environment("BrowserObj")
objBrowser.close
Method2
Environment("BrowserObj") = Browser("creationtime:=0")
Dim objBrowser
set objBrowser = Environment("BrowserObj")
objBrowser.close
How an array is passed using Environment Variable
QTP throws a "this array is fixed or temporarily locked" exception, if we try to pass a fixed length array using Environment Variable.
Dim fixedArr(3)
For i = LBound(fixedArr,1) to UBound(fixedArr,1)
fixedArr(i) = Cstr(i)
Next
Dim dynArr
dynArr = fixedArr
Environment.Value("passArray") = dynArr
