Description
Erases the data value associated with an ini file entry.
System.IniFiles.TMemIniFile.DeleteKey inherits from System.IniFiles.TCustomIniFile.DeleteKey. All content below this line refers to System.IniFiles.TCustomIniFile.DeleteKey.
Erases the data value associated with an ini file entry.
Call DeleteKey to erase a data value associated with an ini file entry. Section is string containing the name of an ini file section, and Ident is a string containing the name of the key for which to set a nil (Delphi) or NULL (C++) value.
Note: Attempting to erase a data value in a nonexistent section or attempting to erase data from a nonexistent key are not errors. In these cases, DeleteKey creates the section and key and sets its initial value to an empty value.
