Error handling with the CompileFromFile function is a somewhat different from most other d3dx functions since it's dealing with compiling hlsl code. If I remember it right you can access any hlsl syntax errors by passing a ID3D10Blob** as the second-to-last parameter ('ppErrorMsgs').

If you want to put the error message in a MessageBox you would need something like

ID3D10Blob* pErrorBlob = NULL;
if (FAILED(D3DX11CompileFromFile("Effects.fx", 0, 0, "VS", "vs_4_0", 0, 0, 0, &VS_Buffer, &pErrorBlob, 0)))
{   
   char* pErrors_mb = static_cast<char*>(pErrorBlob->GetBufferPointer());   
   wchar_t pErrors_w[512];   
   mbstowcs(pErrors_w, pErrors_mb, 512);   
   MessageBox(NULL, pErrors_w, L"Error", MB_OK);   
   return 0;
}

edit: On a sidenote, MSDN recommends precompiling any shader code (for example by using fxc.exe) rather than using this function.
