I have some code which gets the short name from a file path, using GetShortNameW(), and then later retrieves the long name view GetLongNameA().
The original file is of the form
"C:/ProgramData/My Folder/File.ext"
However, following conversion to short, then back to long, the filename becomes
"C:/Program Files/My Folder/Filename.ext".
The short name is of the form
"C:/PROGRA~2/MY_FOL~1/FIL~1.EXT"
The short name is being incorrectly resolved.
The code compiles using VS 2005 on Windows 7 (I cannot upgrade the project to VS2008)
Does anybody have any idea why this might be happening?
DWORD pathLengthNeeded = ::GetShortPathNameW(aRef->GetFilePath().c_str(), NULL, 0);
if(pathLengthNeeded != 0)
{
WCHAR* shortPath = new WCHAR[pathLengthNeeded];
DWORD newPathNameLength = ::GetShortPathNameW(aRef->GetFilePath().c_str(), shortPath, pathLengthNeeded);
if(newPathNameLength != 0)
{
UI_STRING unicodePath(shortPath);
std::string asciiPath = StringFromUserString(unicodePath);
pathLengthNeeded = ::GetLongPathNameA(asciiPath.c_str(),NULL, 0);
if(pathLengthNeeded != 0)
{// convert it back to a long path if possible. For goodness sake can't we use Unicode throughout?F
char* longPath = new char[pathLengthNeeded];
DWORD newPathNameLength = ::GetLongPathNameA(asciiPath.c_str(), longPath, pathLengthNeeded);
if(newPathNameLength != 0)
{
std::string longPathString(longPath, newPathNameLength);
asciiPath = longPathString;
}
delete [] longPath;
}
SetFullPathName(asciiPath);
}
delete [] shortPath;
}
