I am running this simple code

cUserName := "Luis"

If cUserName <> ""
? "Not Empty"
Else
? "Empty"
EndIf

The response is "Empty".
I tried everything that I can think.
Driving me crazy...

Thanks

Try

if len(alltrim(cUserName )) > 0

Luis,

Code: Select all  Expand view

If ! cUserName == ""
   ? "Not Empty"
Else
   ? "Empty"
EndIf

Code: Select all  Expand view

[#include "Set.ch"
FUNCTION MAIN()

? set(_SET_EXACT )
cUserName := "Luis"

If cUserName <> ""
? "Not Empty"
Else
? "Empty"
EndIf

SET EXACT ON
? set(_SET_EXACT )

cUserName := "Luis"

If cUserName <> ""
? "Not Empty"
Else
? "Empty"
EndIf


RETURN NIL
 

SET EXACT
Determines the mode for character string comparison.
Syntax
SET EXACT on | OFF | ( <lOnOff> )

Arguments
on | OFF | ( <lOnOff> )
on | OFF | ( <lOnOff> )
This option toggles if an exact comparison is performed with character strings. or not.
The default is OFF or .F. (false), i.e. characters are compared up the length of the shorter string.
To change the setting use ON or .T. (true) as parameter.
The parameter can also be specified as a logical expression enclosed in parentheses.

Basically this ! variable == "" works
This variable <> "" does not
this variable != "" does not....
