How to check the existence of the object?

[fkwong]

I have a app that uses Winfax SDK but not all the user will have the Winfax installed. Is there a way to check the Winfax Software installation before I make the "fax" option available to them?

I have the following code but it did not work when I try to create the object that is not there.

Thanks!


WAIT WIND "Please Wait! Checking Winfax Software..." NOWAIT
PUBLIC oFax

oFax = CREATEOBJECT("WinFax.SDKSend&quot
WAIT CLEAR
IF TYPE("oFax&quot = "O" AND !ISNULL(oFax)
DO FORM faxacomment
ELSE
MESSAGEBOX("In order to use this option, you need to installed Winfax Software.", 48,"Alert&quot
ENDIF

I believe an error will be generated on the line oFax = CREATEOBJECT("WinFax.SDKSend&quot if it is not installed/registered. You could trap for the error and then bring up your messagebox.
