"File Access Denied" error with read-only files
Hi ...
Whenever my Delphi 3 app tries to open and read a file which is set to "Read-Only" mode, it gives a "File Access Denied" error. I'm opening and reading these files as simple text files. I only want to read from these files, not write to them...so why would I get an error trying to read from them? I know one solution is to change the file's properties to 'Archive', but is there a way programmatically to successfully read these 'read-only' files?
Thanks

P.S: My 'automatic notification' thing is not working whenever you guys answer my questions...how can I fix this?

According to the help file, the Filemode command is not for text files - which is what I'm using. What do I do now?
Thanks

will the file load into a memo or stringlist at all ?
how are you trying to open it?
how are you trying to open it?
The simple way is to use the TStringlist. In fact the TString list has a lot of methodes which can help you to handle the string.
var
MyFile: TStringList;
begin
try
MyFile := TStringList.Create;
MyFile.LoadFromFile(FileNa
finally
MyFile.Free;
MyFile := nil; {Make sure it's memory refrence is freed}
end;
end;
as well see the other 2 way to read the text file
1-Option 1
var
F: TextFile;
S: string;
begin
if OpenDialog1.Execute then
begin
FileMode := 0;
AssignFile(F, OpenDialog1.FileName);
Reset(F);
Readln(F, S);
Edit1.Text := S;
CloseFile(F);
end;
end;
2- Option 2
You can use the TFileStream, which is good as well, but it is not so easy.
var
FStream: TFileStream;
begin
try
FStream := TFileStream.Create(FileNam
Read any part of the file.
finally
FStream.Free;
FStream := nil;
end;
end;
But still the first methode (TStringList), the best and simple way.

Sorry guys...my mistake...yep, I'm an idiot. The problem I was having wasn't with text files after all. It was with the typed files I had - and as soon as I set filemode to 0 as "inthe" suggested, it worked fine. Can you please give "inthe" full marks for his answer.
Sorry!
