[Gambas-user] type mismatch: wanted integer, got string instead

[Dimitris Anogiatis]

MSulchan,

in http://www.gambasdoc.org/help/cat/datatypes you will find a breakdown of
the available data types
supported by Gambas2 and in http://www.gambasdoc.org/help/cat/conv the
available data conversion
functions. In this section of Gambasdoc
http://www.gambasdoc.org/help/cat/type   you will also find
datatype functions that can help you with the special cases... ie IsNULL
will detect if your variable
is null or not.

Now as for a strategy to deal with the floats...

Depending on the floating number's floating part (meaning if the number's
floating part is no more than 2 digits ie 0.90)
seeing as it represents percentage you could always multiply them * 100 and
turn them into an integer. If of course
you get a large number like 0.9999582694 multiplying it by 100 and turning
that into an integer, you'll end up with
rounded data. The other approach is to use a float type variable but then
you need to change your code to handle
floats.

With this new data about your project's input

You could try something like this...
'------------------------------------------------------------------------------------------------------------------------------------------------------
'if the value of sRain is NOT a null

if IsNull(Val(sRain)) = False  THEN

   'if the number is an integer just assign it to the iRain variable
   if IsInteger(Val(sRain)) = TRUE THEN
      iRain = Val(sRain)

     'if it's not an integer
   ELSE
      'check to see if it's a string
      SELECT CASE isString(sRain)
         CASE True

             'if it's a string check here to see which one of the
             'designated strings you have and assign a value to iRain

             if sRain = "x" then iRain = 0.4 'or anything else you want to
make it
             if sRain = "-" then iRain = 0 'or anything else you want to
make it
         CASE False

             ' if it's neither an integer nor a string, convert it into an
integer multiply it by 100 turn it assign it to the iRain variable
             iRain = Val(sRain) * 100
         CASE ELSE
      END SELECT
   ENDIF

'if the value of sRain is a null then just assign a negative integer to
iRain
ELSE
  iRain = -1
ENDIF
'------------------------------------------------------------------------------------------------------------------------------------------------------

I hope this helps a bit more

Regards
Dimitris
