这是个关于装载和保存字符患列表的问题
procedure Tform1.FOrmCreate(........);
var
filename: string;
begin
filename := 'c:\autoexec.bat';
with memo1 do
begin
loadFromFile(filename);
saveTofile(ChangeFileExt(filename,'bak'));
end;
end;
end.
结果出现以下错误:
undeclared identifiler:'loadFromfile'
undeclared identifiler:'saveTofile'
