SFTP ReadDirectory/EOF compile error using BCB5

Hi!
here is a part of my code that i can't compile.
ScSFTPClient is the component that i placed on the form.
Code: Select all
Scclrclasses::TBytes Handle;
Handle = ScSFTPClient->OpenDirectory("Test");
try
{
do
{
ScSFTPClient->ReadDirectory(Handle);
} while (!(ScSFTPClient->EOF));
__finally {
ScSFTPClient->CloseHandle(Handle);
}
Borland C++Builder 5 (Enterprise) won't compile the line with the EOF statement: Error: E2280 Member identifier expected.
Even if i use the popup list (where you can see all the functions and properties - and the EOF property is displayed there!).
If i use the 'Active' property instead (just for a test) it compiles ok.
Any idea what is wrong? Any help how to solve? Are there any more/better examples/demos written in C++ to check?
thanks

EOF' seems to be globally known in this unit (i believe by SecureBridge, not by me. Seems also to be the cause for my other problem - see my other post 'SFTP OnDirectoryList compile error using BCB5').
So if i change the code to this it compiles and works!
Code: Select all
Scclrclasses::TBytes Handle;
Handle = ScSFTPClient->OpenDirectory("Test");
try
{
do
{
ScSFTPClient->ReadDirectory(Handle);
} while (!EOF);
__finally {
ScSFTPClient->CloseHandle(Handle);
}
Hope this will help other C++ programmers

To solve the problem you can add the following lines in the beginning of your cpp unit:

Hi!
I changed code to this:
Code: Select all
#ifdef EOF
#undef EOF
#endif
Scclrclasses::TBytes Handle;
Handle = ScSFTPClient->OpenDirectory("Test");
try
{
do
{
ScSFTPClient->ReadDirectory(Handle);
} while (!(ScSFTPClient->EOF));
__finally {
ScSFTPClient->CloseHandle(Handle);
}
void __fastcall TSftpForm::ScSFTPClientDirectoryList(TObject *Sender,
const AnsiString Path, const TBytes Handle,
TScSFTPFileInfo *FileInfo, bool EOF)
{
FilenameList->Add(FileInfo->Filename);
}
Now it compiles without error, but when executed i get an runtime error in the 'ScSFTPClientDirectoryList' function.
I have it running with my workaround, just want to give a reply that there still seems to be a problem.

Please give a more detailed description of the error that arises in the 'ScSFTPClientDirectoryList' function.

It's an EAccessViolation.
I have 2 files in the remote directory.
So i get 3 events that work well (my 2 files and '.').
On the 4th event, that shouldn't occure, i get the access violation (since there's no (more) filename to read).
So for me it looks like the instruction:
doesn't work right (doesn't recognize/set EOF).
Note:
I placed the
right after the '#include' and '#pragma link' statements, so directly before the code of my SFTP unit beginns.

The last OnDirectoryList event is arised with EOF equaled to True, and this means that the server has passed all the directory list. This behaviour is particularly useful in the NonBlocking mode.
At this case FileInfo is nil, and therefore to solve the problem you should use the following code:
Code: Select all
void __fastcall TSftpForm::ScSFTPClientDirectoryList(TObject *Sender,
const AnsiString Path, const TBytes Handle,
TScSFTPFileInfo *FileInfo, bool EOF)
{
if (FileInfo != NULL)
FilenameList->Add(FileInfo->Filename);
}

Ok, it was my fault - have overlooked this when viewing the 'SFTPClientFrame.pas' example.
Now it works
Can also be coded like this:
Code: Select all
void __fastcall TSftpForm::ScSFTPClientDirectoryList(TObject *Sender,
const AnsiString Path, const TBytes Handle,
TScSFTPFileInfo *FileInfo, bool EOF)
{
if (!EOF)
FilenameList->Add(FileInfo->Filename);
}
