hey zibidian (sorry if ive spelt your name wrong)
thank you for replying to my message, however, i am absolutely useless at programming and i dont understand the help delphi gives. ive only been learning for 2 months or something like that so its all pretty unfamiliar. i dont know if im barking up the wrong tree here but once i program delphi to fill the string grid, would i have to tell it to load file, then fill string grid all in one procedure? also for example if, on my form, i enter a date with a date time picker, would i have to turn that into string for it to load properly on the string grid? possible TDateTimeintostr?! additionally im not sure if im saving the data correctly. what is the save procedure? id be grateful if you could show me some examples of saving and loading files as well as filling in a string grid!
thank you in advance!

Filling a stringgrid can be done by using the build-in editor. The Options property controls if that feature is turned on or not (I don't have Delphi here, but it has a logical name). Here is an example of filling the stringgrid from a comma-delimited textfile:
[code]
var
f: textfile;
s: string;
begin
AssignFile(f, 'somefile.txt');
Reset(f);
SG1.RowCount := 0;
while not eof(f) do
begin
readln(f, s); // read a line from file
SG1.RowCount := SG1.RowCount + 1; // Add a new row
SG1.Rows[SG1.RowCount-1].CommaText := s;
end;
CloseFile(f);
[/code]
I'm not sure what happens if there are more fields per line than Columns in the grid. So the only way to find it out is to try it.
Saving it is very similar:
[code]
var
f: textfile;
s: string;
i: integer;
begin
AssignFile(f, 'somefile.txt');
Rewrite(f);
for i := 0 to SG1.RowCount-1 do
begin
s := SG1.Rows[SG1.RowCount-1].CommaText;
writeln(f, s);
end;
CloseFile(f);
[/code]
You can convert a date and time using the DateToStr() and TimeToStr() functions.
