Can I add comments to a Configuration File?

[R Hibbert]

If so, how?

I want to be able to update the values in the file. At the moment I have lines beginning with a semi colon and am reading from the configuration file, but as soon as I enable writing to the file it gets messed up (="" added to the end of every comment line, header information deleted).

Thanks

Richard.

Richard;

A suggestion can be to add a comment string as a key for each section in the config file.

As far as I know there is no symbol to indicate comments, at least for a fully platform independent configuration file. Some systems use the exclamation symbol "!".

Another alternative is to use a different format, such as XML, if that's possible for your specific application.

Begin and end each comment line with "\\" characters.  Extra carriage return\line feed characters are allowed (to improve readability).  I have only tried this on Windows XP so I don't know if it will work on other platforms.

Here is an example configuration file:

[Button1]
Text=Production Testing
Privileges=Operator,Technician,Admin
VI Path=C:\\C4Test\\Strider\\software\\labview\\Production Testing.vi

[Button2]
Text=Advanced Testing
Privileges=Technician,Admin
VI Path=C:\\C4Test\\Strider\\software\\labview\\Advanced Testing.vi

[Button3]
Text=Maintenance
Privileges=Technician,Admin
VI Path=C:\\C4Test\\Strider\\software\\labview\\Maintenance.vi

[Button4]
Text=Updates
Privileges=Technician,Admin
VI Path=C:\\C4Test\\Strider\\software\\labview\\Updates.vi

[Auxiliary1]
Text=Documents
Privileges=Operator,Technician,Admin
VI Path=C:\\C4Test\\Strider\\software\\labview\\Documents.vi

[Auxiliary2]
Text=Home
Privileges=Operator,Technician,Admin
VI Path=C:\\C4Test\\Strider\\software\\labview\\Home.vi

\\In this configuration file, square brackets enclose each section name. Every section name must be unique.\\
\\Sections contain key/value pairs separated by an equal sign. Within each section, every key name must be unique.\\
\\The key name represents a configuration preference and the value name represents the setting for that preference.\\
