| CIT had confirmed this to be a problem in
Citect for Windows Versions 5.00 to 5.20 (service pack B). The
problem has been fixed for version 5.21.
A work-around for this is to read another value from the object
before you read the tag name. If you call the following Cicode
function from the touch command of a numeric display object, it
will pop up a window listing the tagname that is being
displayed.
FUNCTION
GetTagName()
INT hAN, hInfo, iIndex, iType;
STRING sTagName;
hAN =
KeyGetCursor(); // Find the animation
number clicked on
hInfo = DspInfoNew(hAN); // Create an object
information block for that AN
DspInfo(hInfo, 1, 0); // Work-around
to read a value from the object
sTagName = DspInfo(hInfo, 3, 0);
// Read the tagname
Message("Tag Name", sTagName, 0); // Pop-up window
DspInfoDestroy(hInfo); // Destroy the object
info block when done
END
