Write/Read data from file

[jgd12345]

Hi, I'm working on a project at college and I need some way of storing some data for customer records.

I've looked into types of database but I think it would be easier if I stored it via files. I looked on the delphi help and found the following for writing to files, but don't know how to use it. I would be greatful if someone could give me an example, aswell as an example of how to load from the file to put the data back into an array.

I would be greatful for your help. Thanx

procedure SaveToFile(const FileName: string = ''; Format TDataPacketFormat=dfBinary);

Check out the following link. This Delphi Basics site is very good in giving you examples of how to use code:

Remember, string variables can hold binary data.

with TFileStream.Create(AFileName, fmCreate) do
try
   Write(PChar(DataString)^ Length(DataString));
finally
   Free;
end;
[\code]
and
[code]
with TFileStream.Create(AFileName, fmOpenRead) do
try
   SetLength(FileData, Size);
   Read(PChar(FileData)^, Size);
finally
   Free;
end;
[\code]
