Re: variantconfig bug: If a control name has EOL character, read panel from INI will fail

[PJ M <pjm...@ya...>]

Hi all,
 
When I found that bug, I was actually implementing some error checking. It is based on the following assumption:
1) VI name (containing the saved panel) might be changed in the future
2) Paramater can be added or remove from the panel
and in both case, the "read panel from INI" should work (if possible)
 
In the first case, I check the Section Name[] of the INI against the file name and try to get a match or a best match
In the second case I check the Keys[] of the INI against the controls name and report to the user if the INI is missing anything so the user can manually finish populating what is missing.
 
Regarding the EOL issue, replacing the EOL by space should be enough. The programmer should be aware of the issue by having two controls/indicators with the same name. Returning a warning in such a case is a possibility as well

Hello All,

Philippe submitted the bug shown in the attached email. It is a problem
with variantconfig that effects control names with EOL characters in their
names. Philippe suggests a fix by converting EOL characters to a space. I
think this is a good fix. This will cause the names to appear as a single
line in the INI file. The only possible problem is that there could be a
name collision with a control that has the same name. However, LabVIEW also
allows controls with the same name so this problem already exists. Hmmm,
sounds like we need some error handling... any thoughts? What preconditions
should we be testing for?

- No two controls can have the same names tested after converting all
illegal names to legitimate names (like converting EOLs in control names to
spaces.)

Any others?

Summary: If a control name is on 2 line, read panel from INI will fai

Initial Comment:
If a control name is on 2 line such as
"my control
name"
read panel from INI will fail because the controls was
saved as two different keys on two different lines

Possible Fix: when saving key name, scan string for end
of line or line feed or carriage return and replace it
by a space.
The same thing is required when getting the name of the
control from the variant
