VBPrj folder: C# demo source code
VCPrj folder: VC demo executable file. 
Share_Data_Seg_Dll folder: used with BackplaneInfo.exe together
Programs folder: The executable files and the associated DLL file  

Note:
1.The default working path is located at \temp on the device, so it needs to copy 
all executable files and DLL file to the device in the \temp directory and the all 
files could work.

2. Modify source code to change the working path as following
  2.1 Edit Form1.cs in the \VB_UI_Call_VC_Realtime\VBPrj\RTTPrj
  2.2 Modify the first pararmter of CreateProcess function.  
    CreateProcess("\\temp\\RTTimerP.exe", sparameter, IntPtr.Zero, IntPtr.Zero, 0, 0, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, pi);
  For example,
    CreateProcess("\\temp\\RTTimerP.exe", spara, ...)
    Changed as
    CreateProcess("\\System_Disk\\RTTimerP.exe", spara,...)
  2.3 Rebuild the RTTPrj project
  2.4 Copy all executable files and DLL file to \System_Disk folder.
  
3. VCPrj.exe in the VCPrj folder and RTTimerDll.dll and RTTimerDll.lib in the 
Share_Data_Seg_Dll folder are platform-dependent, so the ARM-based VCPrj.exe, 
RTTimerDll.dll and RTTimerDll.lib used for WinPAC are not applied to XPAC and 
vice versa.
