[Dev-C++] saving text from EDIT control

[Noorez K. <lor...@ho...>]

Sry, resend.

For my program, I need a part that is like a simple text editor, but I can't 
get the 'save' function to work. This error is received while debugging : 
'An Access Violation (Segmentation Fault) raised in your program'  at the 
marked line. I attached the entire program so that you can try to run it.

void SaveText(HWND main)
{
int length;
char* buffer;

length = GetWindowTextLength(GetDlgItem(main, IDC_MAIN_EDIT));

if(length>0)
{
   OPENFILENAME saveFileInfo;

   saveFileInfo.lStructSize = sizeof(saveFileInfo);
   saveFileInfo.hwndOwner = main;
   saveFileInfo.hInstance = gThisInstance;
   saveFileInfo.lpstrFilter = ".TXT"+'\0';
   saveFileInfo.lpstrCustomFilter = '\0';
   saveFileInfo.nMaxCustFilter = 0;
   saveFileInfo.nFilterIndex = 1;
   saveFileInfo.lpstrFile = "Untitled.txt";
   saveFileInfo.nMaxFile = sizeof( saveFileInfo.lpstrFile );
   saveFileInfo.lpstrFileTitle = 0;
   saveFileInfo.lpstrInitialDir = "C:\\";
   saveFileInfo.lpstrTitle = "Hey";
   saveFileInfo.nFileOffset = 0;
   saveFileInfo.nFileExtension = 0;
   saveFileInfo.lCustData = 0;
   saveFileInfo.lpstrDefExt = 0;
   saveFileInfo.Flags = OFN_HIDEREADONLY;
   saveFileInfo.lpfnHook = (LPOFNHOOKPROC)0;
   saveFileInfo.lpTemplateName = 0;


   GetSaveFileName(&saveFileInfo); //error is here in debugging
   buffer = new char[length+1];
   GetDlgItemText(main, IDC_MAIN_EDIT, buffer, length + 1);
   ifstream saveTextFile("SaveText.txt", ios::binary);
   saveTextFile >> buffer;
   saveTextFile.close();
   delete buffer;

}
}
