<p class=MsoNormal>Dear all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m trying to create a new component in C++ with a
dynamicdata function.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>It works when I build the solution in C++, but pulls out
following error when I run this component in TRNSYS:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>“Access violation at address 100048CC in module
‘TRNDLL.DLL’. Read of address 00000002”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Does anyone has some experience in using the dynamicdata
function in C+ and can help me out?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks very much in advance<o:p></o:p></p>
