Title: Adding Text to Log Files
Question: How to add a line of text to the log file without using memos or other visual components?
Answer:
Use this function:
function AddTextToFile(const aFileName, aText: string; AddCRLF: Boolean): Boolean;
var
lF: Integer;
lS: string;
begin
Result := False;
if FileExists(aFileName) then lF := FileOpen(aFileName, fmOpenWrite + fmShareDenyNone)
else lF := FileCreate(aFileName);
if (lF = 0) then
try
FileSeek(lF, 0, 2);
if AddCRLF then lS := aText + #13#10
else lS := aText;
FileWrite(lF, lS[1], Length(lS));
finally
FileClose(lF);
end;
end;
