Grab Viewport Plus

Update:
v.1.1 -- directory string bug fixed
v.1.2 -- FiXed: expert mode is only working when viewport is not maximized

Usage Notes:
All script settings are stored in INI file in Max "ui\macroscripts" folder.
[*] Hold Control key while executing to load the INI file for editing.
Yes, I know, the most people prefer GUI where to enter the configs, but
the names of all keys are descriptive, so not the big deal to edit them.

-- their is the default contents of the INI file:

[Settings]
SaveToFile=1
MaximizeViewport=1
DisplayInVFB=1
Directory=C:/3ds Max Screenshots
FileName=img_
FileFormat=.jpg

First 3 keys are boolean values. 0 = disable , 1 = enable

"SaveToFile" -- enable/disable saving. 
"MaximizeViewport" -- toggle Expert Mode + Maximize Viewport. 
"DisplayInVFB" -- whether to display or not the shot. 
"Directory" -- is the output path. 
"FileName" -- is the base prefix. 
"FileFormat" -- the output file format.

Error handler:

To prevent errors while keeping the code simple, I end with this:

• Disable first 3 options by set their value to 0 and
  enable them by set their value to 1 (or whatever else different from 0).
• If the directory not exist the Max "previews" folder will be used insted,
  e.g.: C:\Documents and Settings\USER\My Documents\3dsmax\previews
• If "FileName" key is empty, the "img_" will be used by default.
• If you set an invalid file format (i.e. that Max not support) then
  the JPEG (.jpg) will be used by default.

Installation: Typical/normal macro script installation.
