Hi,
Do strings have a maximum length ?
If yes, is there a way to retrieve a longer string from DLL procedure ?

ProcedureDLL.s GetDialogXML()
   Global xml.s="<dialog>"+
                "......"+
                "......"+
                "......"+
                "</dialog>"
   
   ProcedureReturn xml
EndProcedure

Code: Select all

Runtime strings: no, they're unlimited.

A literal string is different: they're strings that you've physically
typed into the IDE. These have a limit of 8192 characters.

Just split it up:

Code: Select all

ProcedureDLL.s GetDialogXML()
   Global xml.s="<dialog>"+
                "......"
          xml.s+"......"+
                "......"+
                "</dialog>"
   
   ProcedureReturn xml
EndProcedure

I see.
Thanks

This limitation, and the distinction between a string literal and a string variable should really be spelled out in the Help file, in the "Variables & Types" page.

There is nothing obvious about it, but there is no explanation given about it.

Thank you for this : )

Or get it from an XML/TXT file directly (if the content doesn't change):

Code: Select all

ProcedureDLL.s GetDialogXML()
  Global xml.s=PeekS(?TXT_Start,-1,#PB_Ascii)
  ProcedureReturn xml
EndProcedure

DataSection
  TXT_Start:
  IncludeBinary "C:\Path\To\Large\XML_file.xml"
  Data.c 0 ; End of text marker.
  TXT_End:
EndDataSection
