Title: Writing a file from a string
Question: How can I save the contents of a string in a file?
Answer:
The following procedure "SaveFile" receives a file name as parameter and
the string we want to save in it. If the file does not exist, it is
created, and if it exists, its previous content is discarded.
procedure SaveFile(const FileName: TFileName;
const content: string);
var
Stream: TFileStream;
begin
Stream := TFileStream.Create(FileName, fmCreate);
try
Stream.Write(Pointer(content)^, Length(content));
except
Stream.Free;
raise;
end;
Stream.Free;
end;
Sample call:
SaveFile('test.txt', 'ABC'); // Stores "ABC" in the file "test.txt"
