我有一些代码从文件路径获取短名称,使用GetShortNameW(),然后检索长名称视图GetLongNameA()。
原始文件的格式为
"C:/ProgramData/My Folder/File.ext"
然而,在转换为short,然后返回long,文件名变为
"C:/Program Files/My Folder/Filename.ext".
短名称的格式为
"C:/PROGRA~2/MY_FOL~1/FIL~1.EXT"
短名称未正确解析。
代码在Windows 7上使用VS 2005进行编译(我无法将项目升级到VS2008)
有人知道为什么会这样吗?
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;
}
答案 0 :(得分:1)
反之亦然:GetShortPathNameA和GetLongPathNameW。
GetLongPathNameA不一定成功。 只有8.3个路径名[部分保证]与ANSI兼容。
