Get an integer value which only has address of this variable (transfer() function)

pcsoft.us.windevCopyright 2026, PC SOFT17 Oct 2015 16:17:00 Z16 Oct 2015 15:48:00 ZHi, I am working on a dll file in Windev. I have a callback function which has one parameter returned by system. I can only get the address of this variable (the third parameter: nResponseAddress), it keeps a unsigned long variable in C. I used system int to keep the address. How do I get the value in this address? I read some document from Windev website. I saw there is a function Transfer( , , ) However, from the document about my callback function the value in here is supposed to be either 1 or 2. But Windev returns 16. Did I missed something? Here is my code: PROCEDURE CallBackControl(sMyConext is string, nStateMask is system int, nResponseAddress is system int, nSignal is system int, nBitmapAddress is system int) nResponseValue is int nResponseTempAddress is system int = &nResponseValue Transfer(&nResponseValue,nResponseAddress,4) After I run this function, nResponseValue is 16.
