If Blocking=1, then page wizards should return some values via the parameter file’s Output section.
The ExitStatus key should be set to either “error,” “cancel,” or “OK.” If ExitStatus is not present, the launching program will assume that an error occurred in the wizard.
If Destination=disk, the wizard should write a FileCount key and a list of keys from File1 to FileN and Url1 to UrlN. The values of these keys should be set to the absolute paths and target URLs of each file generated by the wizard.
For example, a wizard that generated two files might create an Output section like this:
[Output]
ExitStatus=ok
FileCount=2
File1=c:\temp\wiz01.tmp
Url1=index.htm
File2=c:\temp\wiz02.tmp
Url2=test.htm
It is assumed that File1 will be the main HTML file created by a page wizard.
