Hi all I have a strange problem with using web services.

I have a web services that sends more than one variable as a result. if one
of those result veriables which is the date type returns null,web service
raices an exception telling "there is an error in xml file(x,y)" so I cant
catch other returning variables because my service crush...

But I call the same web services using same wsdl file with a power builder
app it works well,I mean all variables returned right and that date types
variable null too(but it doesnt matter)

So is there a bug using web services with null dtae in vb.net or how Do I
handle this error and have right returning variables even that date variable
is null.
I hop I could tell wat my problem is.
thanks...
