Hey there,

how can i handle NULL Objects in Fin250?

I get runtime errors whenever i try to assign an Empty-Object to an other Object.

For example (msxml-Automation):
ReturnedNodeList := RootNode.selectNodes(NodePath);

If RootNode.selectNodes(NodePath) returns the NULL-Object, i get an error message.

Any ideas?

How can i simulate the ISCLEAR-function from attain?

thanks in advance

    I tried something like :

    IF RootNode.selectNodes(NodePath).nodeName <> '' THEN ...

    But it doesn't work. I'm getting an error message that the object is not instantiatet.
