Decide what operation you want to perform when the ‘Help’ button is clicked as shown below
The 
button will not be displayed in the wizard so the user can see it
if the text field in the figure above is not empty. In this field, you may
specify one of the following:
• A link to a web page, example: www.winmls.com
• An
identifier that opens a page in the WinMLS help file. The identifier is composed
by ‘IDH_’ plus the heading name. If there are spaces or punctuations in the
heading name, use ‘_’.
Example: If the heading is “Calculate Menu” you must
write “IDH_Calculate_Menu”.
Example: If the heading is “Load...”, you must
write “IDH_Load___”.
• A
file that exists on your hard disk, example: test.txt. Any file format is
supported if you PC has the software for opening the document. It is recommended
to move these files to the subfolder named Docs in the folder where
WinMLS is installed. If you do this, you do not need to specify any path for the
files and these documentation files will be included if you export the setup. Click the 
button to open a file from your hard disk.
Click the 
button to check if what you have specified is correct.
