Hi,
In the documentation for an app. written by someone else it says:
Call RegisterWindowsMessage(PChar('SOMEUNIQUESTRING')) and then monitor
the windows procedure for the registred message ID.
When the message is received lParam will contain a pointer PChar to a
string containing the data.
This means that in that app. there must be code like this:
var
S: string;
S := 'Pass this data to other application';
BroadcastSystemMessage(BSF_POSTMESSAGE,@Recipients,MsgID, 0,
Integer(PChar(S)));
But there is something I don't understand here. The two applications
have different memory address spaces so how can this work?
In other words how can the other application fill data and pass a
pointer to that data that my application can actually access?
As its actually working my question is more out of curiosity than
anything else :-)
Hope someone here can educate me. Thanks in advance.
