The following code worked in 1.0.47.06 but fails in 1.0.48.05 (error handling code not shown). The TextLen is retrieved correctly but the Text variable is empty (because the Temp variable is empty after the call to the FileRead function to retrieve the text).
Code:
;Get length of text in file (including trailing null)
FileRead( handle, Temp, 4 )
TextLen := NumGet( Temp )
;Get text
FileRead( handle, Temp, TextLen )
Text := Temp
;FileRead function
FileRead( handle, ByRef Result, Length )
{
VarSetCapacity( Result, Length, 0 )
DllCall( "ReadFile", handle, Result, Length, ... )
}
If I remove the use of the Temp variable when retrieving the text it works fine. For example:
Code:
;Get length of text in file (including trailing null)
FileRead( handle, Temp, 4 )
TextLen := NumGet( Temp )
;Get text
FileRead( handle, Text, TextLen )
It appears that AHK doesn't like the fact that the Temp variable was previously used to get the text length before it was filled with the null terminated text string.
