Hi Pavel. > Did you declare your procedure GetDriver as exported in a bpl?
No. I found that problem about an hour after posting. However, now, when running the code, I get a runtime error stating that 'Application is not licensed to use this feature'. I wrote about this in my previous post. I've tried toying with my exported procedure and found that this latest problem has to do with the fact that I'm passing an object that is of the super-class type, and initializing it (in the GetDriver procedure) as a subclass. How would I go about exporting the class? Thanks for all the help, Assaf. -----Original Message----- From: Pavel Evarestov [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 21, 2005 8:45 AM To: [email protected] Subject: [delphi-en] Re: Problems loading a BPL package dynamically in D7 Hi, Assaf! >What I do is, locate the file, then run LoadPackage, and then >GetProcAddress, to run the procedure (GetDriver) that returns the >driver object (the procedure creates the proper subclass of the parent >driver class). However, when I run the code, the driver procedure >(ExecF) is unassigned, and that of course, is not what should be. Did you declare your procedure GetDriver as exported in a bpl? > @ExecF := GetProcAddress(phm, 'GetDrive'); May be this is a cause of a problem? You've written, that your procedure is called "GetDriver', but in above line of code you try to get an address of "GetDrive". Another question is: are there any reasons that prevent you from creating your object straignt from the package, something like this: aPointSensorDrv:=TPointSensorDrv.Create(...); What is the reason for using special procedure "GetDriver"?
