Property
Specify a property name. It will hold the result of the search, which is a file
name, directory path, or other value, depending on the operation performed by
the search. If you’ve already defined a new public property (all uppercase) in
the Properties icon on the Product tab, then you can select it from the list;
otherwise enter a new property name (all uppercase). If you enter a new
property name, and the search fails to find a match, the property value will be
null and will be false if used in a condition.
Operation
Select the type of entry for the property:
Read directory name from INI file
Use this only if the .INI information you are searching for is a directory path.
A search of this type returns the entire directory path. Example:
E:\Application\.
If you use this operation on .INI information that’s in the form of a file path,
or any other form, then this type of search fails. The search also fails if there
is more than one value listed for the item, separated by commas.
Read file pathname from INI file
Use this only if the .INI information you are searching for is a file path.
Example: E:\Application\Application.exe. However, the file name itself is
dropped from the search result. A search of this type returns the directory
path only, minus the file name. Example: E:\Application\.
If you use this operation on .INI information that’s in the form of a directory
path, or any other form, then this type of search fails. The search also fails if
there is more than one value listed for the item, separated by commas.
Read raw value from INI file
Use this to find any type of .INI information. This type of search has the
added benefit of letting you specify the Item Field, which determines which
value in a comma-delimited list of values to retrieve. Example: If you set the
Item Field to 2 and search this item:
Colors=red,blue,green
“blue” is returned because it is the second field in the item.
INI File Name
Enter the name of the .INI file. (Not case-sensitive.)
INI Section Name
Enter the section name that contains the item you’re searching for. Although
section names are enclosed in brackets, don’t include the brackets. (Not case-
sensitive.)
INI Item Name
Enter the name of the item that contains the value you’re searching for. (Not
case-sensitive.)
Item Field
This is enabled if you select Read raw value from INI file in the Operation
field. If the item you’re searching for contains several values, separated by
commas, enter the number of the value’s position in the list of values or enter 0
to get all values.
