<DIV><FONT size=2>hi,</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>I try to use a call_external in an object method like
this:</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT face="Times New Roman" size=2>pro MCP2000__DEFINE<BR> struct =
{MCP2000, hComm: 0l, status: 0l}<BR>end<BR></FONT></DIV>
<DIV><FONT face="Times New Roman" size=2>function MCP2000::Init<BR>self.hComm
= 0l<BR>return, 1<BR>end<BR></FONT></DIV>
<DIV><FONT face="Times New Roman" size=2>function
MCP2000::InitPort<BR> self.status=call_external('D:\Cpp\SerCommDll\Debug\SerCommDl l.dll','InitPortDll',$ <BR> /PORTABLE,'COM1',self.hComm
,/UNLOAD)<BR>return, self.status<BR>end<BR></FONT></DIV>
<DIV><FONT size=2>the idea is here that self.hComm contains a valid handle,
but it doesnt - it stays zero.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>However, this works</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT face="Times New Roman" size=2>function
MCP2000::InitPort</FONT></DIV>
<DIV><FONT face="Times New Roman"
size=2>Temp=0l<BR> self.status=call_external('D:\Cpp\SerCommDll\Debug\SerCommDl l.dll','InitPortDll',$ <BR>
/PORTABLE,'COM1',Temp,/UNLOAD)</FONT></DIV>
<DIV><FONT face="Times New Roman" size=2>self.hComm=0l<BR>return,
self.status<BR>end</FONT></DIV>
<DIV><FONT face="Times New Roman"></FONT> </DIV>
<DIV><FONT size=2>any ideas what goes wrong in the first
function????</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Gert</FONT></DIV>
<DIV><FONT size=2></FONT><FONT size=2></FONT> </DIV>
