<DIV>Yes, I did! The problem is the generating of _ (underscore) beofre the function name. So in the lib there is the function _type201. Solution is very simple: use option __stdcall.<BR></DIV>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN lang=EN-GB style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Basically it shouldnt matter what tool you use to create the DLL. The problem can be on two levels:<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN lang=EN-GB style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">Either the function implementing the type is not exported in the DLL, or TRNSYS doesnt recognize it. <o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN lang=EN-GB style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">To check the first, simply use a tool like the dependency walker to look at your DLL (Microsoft gives one away for free type depends.exe in google to find it). A correct DLL should show a C-style function called TYPE201 (with a little little grey C in the line that lists it). If it isnt there, you have trouble telling your compiler to export the function. In the Microsoft world, one way to say this is the line <o:p></o:p></SPAN></FONT></P>

<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN lang=EN-GB style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">To check the second, make sure your type returns 1 at every possible exit point. If its a complicated one, try a simple one first (like one saying only return 1; ).<o:p></o:p></SPAN></FONT></P>
