TMemIniFile.DeleteKey Method

Deletes a specified entry from the .ini file.

Pascal
procedure DeleteKey(const Section: String; const Ident: String); override;
C++
virtual __fastcall DeleteKey(const AnsiString Section, const AnsiString Ident);
Description

Call DeleteKey to erase .ini file entry. Section is string containing the name of a .ini file section, and Ident is a string containing the name of the key to remove.

Note: Attempting to erase a key in a nonexistent section or attempting to erase a nonexistent key are not errors. In these cases, DeleteKey does nothing.
DeleteKey only affects the in-memory copy of the .ini file, not the copy on disk. The change is not written to disk until you call UpdateFile.
