change string into an integer

[Michiel Spape]

Hi Mark & group,
I understand that string InitialValue takes a value from attribute InitialValue (i.e. [InitialValue]), which in turn refers to nested attribute [Value02]? 
1. Why do you not just have vCount = c.GetAttrib("Value02")?
2. Attributes themselves are like (or just are?) variants, which VisualBasic slightly awkwardly casts depending on their value. Point is:
Dim vCount as integer
vCount = c.GetAttrib ("InitialValue")
vCount = vCount + 1 'or whatever you do with your intial value
c.SetAttrib "InitialValue", vCount
...should also work, as long as the value of [initialvalue] actually was found to be a number
3. All of that should hardly matter, but if vCount has value of "Value02" (rather than [Value2]), my quick guess would be that your nested attribute is wrongly set to be Value02 instead of Value02. So:
vCount = c.GetAttrib("InitialValue") 'is where it goes wrong
...adding the following line should give you a quick check to see whether this is tru:
debug.print cstr(vCount) 'shows value in output log.
If this shows a) nothing at all, or b) a value that is not a number (like 'Value02'), then quite obviously, you cannot change this into an integer. Although, if you like, you can change Value02 into an integer of 02 (i.e. 2) by doing something like 
Dim newvalue as integer
Newvalue = cint(mid(vCount,6,2))
(not sure on exact syntax)

Best,
Mich

Subject: change string into an integer

I have a question regarding the changing logged data from a string
into an integer. I have a little bit of script before a label which
designates the starting values in a trial which is:

Dim vCount As String
Dim pCount As String
Dim InitialValue As String
Dim InitialPie As String
vCount = c.GetAttrib("InitialValue")
pCount = c.GetAttrib("InitialPie")

at the end of a second inline, this little bit of script logs the data
designated in the first.

c.SetAttrib "InitialValue", vCount
c.SetAttrib "InitialPie", pCount

pCount is fine but vCount logs value of Value02, which is a nested
attribute. I would like to have it return the value contained in the
attribute "Value02". I've tried to make this happen a number of
different ways, e.g. CInt(vCount), CStr(CInt(vCount) + 0), etc.) but
each time i get an error message of type mismatch. is there any way to
change this string into an integer?
