Excel User Defined function calling RTD
Hi,
I have an Excel user defined function (UDF) lets say udf1 implemented in an XLL. udf1(X) // Excel UDF defined in an XLL taking 1 argument This UDF calls a RTD server using the RTD function with 3 arguments RTD("RTDServerName", "", int X, int arg2, int arg3) I have an Excel sheet saved with this UDF. Now lets say the implementation of the RTD server has changed and the type of arg2 changed incompatibly. Eg: RTD("RTDServerName", "", int X, String arg2, int arg3) // Arg 2 changed from int - String I also changed the XLL so that the UDF calls the new RTD function correctly. But somehow the Excel sheet that was originally saved seems to remember that the RTD was called with an int argument and the RTD server seems to be getting called with the integer argument. The new RTD server does not like the argument and it fails the request. Is this normal? Is this RTD call caching some feature of Excel that can be disabled? Thanks |
