示例1: GetCurrentDirectoryX
bool GetCurrentDirectoryX(std::basic_string<Char, Traits, Alloc>& out)
{
Blob<Char> buf;
//TCHAR* tsz = 0;
DWORD dwRet = 0;
bool r = false;
dwRet = GetCurrentDirectoryW(static_cast<DWORD>(buf.Size()), buf.GetBuffer());
if(dwRet)
{
if(dwRet > static_cast<DWORD>(buf.Size()))
{
// It needs more space.
if(buf.Alloc(dwRet+2))
{
if(::GetCurrentDirectory(static_cast<DWORD>(buf.Size()), buf.GetBuffer()))
{
out = buf.GetBuffer();
r = true;
}
}
}
else
{
out = buf.GetBuffer();
r = true;
}
}
return r;
}示例2: LoadLibraryX
inline HMODULE LoadLibraryX(const Char* buffer)
{
Blob<wchar_t, false, BlobTraits<true, MAX_PATH> > t;
t.Alloc(StringLength(buffer) + 1);
t.GetWritableBuffer()[0] = 0;
XLastDitchStringCopy(buffer, t.GetWritableBuffer());
return LoadLibraryW(t.GetBuffer());
}示例3: LoadStringX
inline int LoadStringX(HINSTANCE hInstance, UINT id, Char* buffer, int buffermax)
{
