A MFC programming with spontaneous since the test code, defines the frame ID FFFFFFFF, display ID always received 1 FFFFFFFF, relevant code below
Define the ID
If (frameinfo ExternFlag==1)//extension frames
{
Sscanf (m_EditSendFrmID, "% x" 08, & amp; n);
Frameinfo. ID=n;
}

Read ID with program
Len=VCI_Receive (DLG - & gt; M_devtype, DLG - & gt; M_devind, DLG - & gt; M_cannum frameinfo, 50200);
.
TMPSTR. The Format (" frame ID: % x "08, frameinfo [I] ID);
STR +=TMPSTR;
.

How ID defined? Have more than 1 _ffff_ffff 32 bit?

define ID? Have more than 1 _ffff_ffff 32 bit?

User manual said frame ID is a 32-bit UINT variable
When I start set the ID to 8 f, adopts the model of spontaneous since closed, received the ID of the display for a 1 + 7 f, don't know where is the problem,

Breakpoints can only be set where there is corresponding to the assembly instruction,
