CFile::Open flags in LoadFromFile

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic


   The CXTPGraphicBitmapPng::LoadFromFile has such code:
/---
 CFile file;
 if (!file.Open(lpszFileName, CFile::modeRead))
 {
  return FALSE;
 }
---/
The code can result in failing to load an image if two instanses of a program will try to open the file.
I think you should change flags for CFile::Open
/---
  CFile file;
  if (! file.Open(lpszFileName, CFile::modeRead | CFile::shareDenyWrite))
 {
  return FALSE;
 }
---/
