I have DLL named SIP.DLL. This DLL contain function SendLine.
I want use it. In VFP I use command
DECLARE INTEGER SendLine IN SIP.DLL STRING cPort, STRING cString, STRING cAddress, STRING cFlowControl
This command work o.k. Next I use command
nRetVal=Sendline('1','Text','1')
When I use this command VFP return error 'Cannot find entry point
SendLine in the DLL'. What does it mean?
Name of function SendLine is correct, because I have another program
in C++ which use SendLine and this C++ program work o.k.
