Hi all, I am working with a COM interface and the specification which is wrtten for ASP calls for a "Currency" data type to be passed to a function. What is the equivalent in PHP? If I call com_print_typeinfo() I can see that the function has the following info: function GetPrice( /* VT_PTR [26] [in][out] --> VT_VARIANT [12] */ &$Account, /* VT_PTR [26] [in][out] --> VT_CY [6] */ &$Quant, /* VT_PTR [26] [in][out] --> VT_I2 [2] */ &$QuantMult, /* VT_PTR [26] [in][out] --> VT_I2 [2] */ &$prMult ) The parameter I am having problems with parameter 2 - $Quant. I tried to create a VARIANT of type VT_CY so I did: $qty = new VARIANT('1.0000', VT_CY); The error I am getting is: Uncaught exception 'com_exception' with message 'Parameter 2: Type mismatch.
