Emacs Mark Region and Scrolling Problem

The problem looks like this in emacs when I set the mark:

1. C+SPC set the mark at the beginning of the paragraph

2. Move to the end to paragraph.

3. If I need to scroll the page in step 2, the cursor will move to the current view of the emacs

4. Then I use left click to select the region between the start mark and current cursor. But I only get part of the region that in the current view.

After making me depressed a long time, I realized that the reason is due to the failing of set mark in step 1. C+SPC is not captured by Emacs, but by my Input Method.

Synchronize the folder to the server in the Rstudio

1. Install the WinSCP

2. Set WinSCP installation path to the WIN7 Environment Variable in $PATH

3. Write the code:
1. Winscp_sync.txt:

                  open stored_session_name_in_WinSCP

                  synchronize both E:\Projects\R\data\server /homed/home/shi/anthony/tfbs_pwm/rsnp

                  exit

2. Winscp_sync.bat:

                WinSCP.exe /console /script=winscp_sync.txt

4. In Rstudio

               Call: system('./winscp_sync.bat')#Path needed
