GetCurrWrd | R Documentation |
Look for a running Word, resp. Excel instance and return its handle. If no running instance is found a new instance will be created (which will be communicated with a warning).
GetCurrWrd()
GetCurrXL()
a handle (pointer) to the running Word, resp. Excel instance.
When closing an application instance, the value of the pointer in R is not somehow automatically invalidated. In such cases the corresponding variable contains an invalid address.
Whether the pointer still refers to a valid running application instance can be checked by IsValidHwnd
.

# now it should be gone and the pointer invalid
