Hi to all,

I have the following code:
//... some stuff
    if (FindFirst(this->wpath + "\\" + this->filefilter, iAttributes, sr) == 0)

    {
      do
      {
        if ((sr.Attr & iAttributes) == sr.Attr)
        {

          if (this->DebugLevel >= debug_level)
              ODebug_(this->LogName,
                      this->GetTimeStamp()+" [File Found] " + sr.Name);
          files->Add(sr.Name);
          TStream *file = new TFileStream(this->AppPath + sr.Name, fmOpenRead); // << I;m getting Open File error
          //this->InsertFile(sr.Name);
          //this->FileMove(sr.Name);
        }
      } while (FindNext(sr) == 0);
      FindClose(sr);
    }

While I'm getting a file open error when I try to open the file
using TFileStream?
FindFirst open the file?

Thanks in advance

Ok. Thanks for all, but I fixed.

>      FindClose(sr);
 I have to close every time that I do FindNext

You are not specifying any sharing rights:

    TStream *file = new TFileStream(this->AppPath + sr.Name, fmOpenRead |
fmShareDenyWrite);

Hi Gambit,

yes, but anyway, I only want to open the file using TClientDataSet
(there are XML files), but I was getting an EFOpen File error
using the TFileTream (using LoadFormFile). I could find that the FindFirst/FindNext
open the file with no shared.
I solved this using FindClose() after FindNext.

You need only one FindClose() for the given FindFirst() and all subsequent
FindNext().
The error that occurs in your code may be resulted from the proposoal that

this->wpath + "\\" + sr.Name

is not the same as

this->AppPath + sr.Name
