EOF does not reset

Post by HBL » Wed 14 Nov 2018 13:49

When I try to open a file, then read it and close it using closehandle. If I then try to open another file or the same file, then EOF is not set to false, but stays at True from last time.

System: Delphi XE5 Update 2, Windows 10 Pro, SecureBridge 8.2.4

I even tried to disconnect and reconnect without it being reset to false when I call Openfile.

Code:
var
Handle: TBytes;
Begin
ScSFTPClient1.connect;

For I := 0 to 5 do Begin //Loop, just for testing
Handle := ScSFTPClient1.OpenFile('/test/2018-01-05_panelists.txt', fmOpenExisting, [], [bmWrite, bmDelete], [amReadData]);
Try
//First time ScSFTPClient1.EOF is False, second time it stays True and the code inside While is not executed.
While not ScSFTPClient1.EOF do
//Do ScSFTPClient1.ReadFile here
Finally
CloseHandle(Handle);
end;
end;

ScSFTPClient1.Disconnect;
Anyone have solution to this, its a pretty wierd if no one have seen it before ?

To solve your task, please try to use the following code:

Code: Select all

repeat
//Do ScSFTPClient1.ReadFile here
until ScSFTPClient1.EOF;
instead of

Code: Select all

While not ScSFTPClient1.EOF do
//Do ScSFTPClient1.ReadFile here

I got it working using the Repeat sentence

I see now that the EOF flag is set by ReadFile, so by checking it on second loop before Readfile will always yell True because of the previous loop.

Idea:
Would it be better if the call to OpenFile resets the flag to False, so both While and Repeat would work?

We have already fixed this issue, the fix will be included in the next SecureBridge build, which we are planning to release within a week.
