Hi,

but how to find empty strings [""] in code?

best regards,
Xavier

Hi Xavier,

Not sure I get your question completely but here's what I used to do:
IF SomeString ~= "" THEN ...
or
FOR ALL String SubStr OF MainStr SEPARATED BY CR
IF Substr ~= "" THEN ...

Cheers,

Hi Peter,

I want to find in the code editor all the [""] like EDT_Name = "",
so do a Ctrl-F in the code editor and try to find all the double double quotes in the code.

Cheers, Xavier

Ah, OK.
Not working in WX at the moment...
But by heart: You need to quote your search again in that case if I recall correctly.
Something like "=""" or maybe like in code where you have to quadruple your quotes.
Something like """""""" maybe.

Do some tests, I have used it that way quite a while ago.

Cheers,

Hi Peter,

I've tried "", """, """" => nothing found
just tried """"" (5 double quotes) and now WD finds them...
