Substring on a Substring Runtime Error
Posted: Wed Jun 14, 2017 6:21 am
I am getting an unhandled runtime error when I try to do a substring on a substring'ed string.
For example, this code triggers the error.
The delimiterPosition correctly comes out to 10 (which is less then the attribute length so it should not be a length issue). The PositionOf function here works, but in a ServerRoutine (where I initially experienced this) the error would happen on PositionOf.
Here in a Windows Form it happens on the Substring.
Here is the x_err.log
For example, this code triggers the error.
Code: Select all
evtroutine handling(#Button1.Click)
define_com class(#PRIM_ALPH) name(#stringToParse)
define_com class(#PRIM_ALPH) name(#attribute)
define_com class(#PRIM_ALPH) name(#attributeName)
define_com class(#PRIM_NMBR) name(#delimiterPosition)
#stringToParse := "username|attribute:value"
#attribute := #stringToParse.Substring( (#stringToParse.PositionOf( '|' ) + 1) )
#delimiterPosition := #attribute.PositionOf( ':' )
* error occurs here
#attributeName := #attribute.Substring( 0 #delimiterPosition )
endroutine
Here in a Windows Form it happens on the Substring.
Here is the x_err.log
Code: Select all
