 |
|
I have an edit dialog that im trying to save in an application but it appears as though control characters are causing it to only save the first line if I do a carriage return in the edit field.
| Code: |
DIALOG ADD,EDIT,EDIT5,205,21,927,389,,,MULTI,BLACK,SCROLL,TABS,WRAP
%%notez = @dlgtext(EDIT5)
%%saveticket = %%date|%%ticketid|%%source|%%destination|%%message|%%notez
|
I tried using @trim to no success. What am I missing here or is something else causing this?

One or both of two possibilities could be causing your problem. I assume you're placing the var "%%saveticket" into a list and saving it to a text file as a flat database. In which case the problem should be apparent by looking at text of the saved file. If there are additional lines between data rows containing a portion of the text from the %%notez field above there are LF and CR characters being saved within the %%notez string. Another problem could be extra flied separator characters are being typed into the edit control by the user to latter be misinterpreted by the parse command.
To resolve the above mentioned you need to validate every char a user types into your program. I use the following, hope it helps.
| Code: |
#define function,TxtOnly
%%notez = @TxtOnly(@dlgtext(EDIT5))
:TxtOnly
# This function strips ALL control chars
# Returns a single line string between #32 - #126
# Also strips the feild sep char
# Carrage Returns replaced by White Space
%R =
%S = @asc(@fsep())
%L = @len(%1)
if @greater(%L,0)
repeat
%C = @asc(@substr(%1,%L))
if @greater(%C,31)
if @greater(127,%C)
if @unequal(%C,%S)
%R = @chr(%C)%R
end
end
elsif @equal(%C,13)
%R = @chr(32)%R
end
%L = @pred(%L)
until @zero(%L)
end
exit %R

Use @text() instead of @dlgtext()
You might even want to place quotes at both ends of the string since you're
placing %%notez in to another variable
| Code: | DIALOG ADD,EDIT,EDIT5,205,21,927,389,,,MULTI,BLACK,SCROLL,TABS,WRAP
%%notez = @chr(34)@text(EDIT5)@chr(34)
%%saveticket = %%date|%%ticketid|%%source|%%destination|%%message|%%notez |

Ooops, You're right WidgetCoder
I haven't had this problem with control characters in multiline edit boxes before. However I usually place quotes around questionable groups of text.
| Code: | DIALOG ADD,EDIT,EDIT5,205,21,927,389,,,MULTI,BLACK,SCROLL,TABS,WRAP
%%notez = @chr(34)@dlgtext(EDIT5)@chr(34)
%%saveticket = %%date|%%ticketid|%%source|%%destination|%%message|%%notez |
One thing I have noticed is that not resetting OPTION FEILDSEP back to (|) can sometimes have undesirable results when placing the contents of a control into variables.
Just as a test the following seems to work without any problems:
| Code: | Title Multiline Edit Test
DIALOG CREATE,New Dialog,-1,0,485,234
DIALOG ADD,EDIT,EDIT1,23,22,442,139,,,MULTI,SCROLL,TABS,WRAP
DIALOG ADD,BUTTON,BUTTON1,189,215,64,24,DLGTEXT
DIALOG ADD,BUTTON,Close,190,350,64,24,Close
DIALOG SHOW
:Evloop
wait event
goto @event()
:BUTTON1BUTTON
%N = 0
REPEAT
#Create a string of all ascii characters
%N =@SUCC(%N)
%%FILL = %%FILL@CHR(32)@CHR(%N)
UNTIL @EQUAL(%N,255)
DIALOG SET,EDIT1,%%FILL
#Wait a couple of seconds to see %%FILL in EDIT1
WAIT 2
%%EDIT1TEXT = @DLGTEXT(EDIT1)
%%NEWVAR = Add contents of EDIT1 to this string|%%EDIT1TEXT
INFO %%NEWVAR
goto evloop
:CloseBUTTON
:Close
exit |

Quoted strings only escape special chars in hard code. You could still have issues with LF/CR and the user entering a field separator. The parse command will still interpret {"sometxt | somemoretxt"} as {"sometxt |} from a saved file. I only use the example above on multi style edits normally I parse edits with @pos() and use @strdel().
