variant

[jeff at HCT]

I need help understanding how to extract data from a variant of an activex.

VARIANT my_data_1[1];

error_code = DATAQSDKLib__DDataqSdkGetData (dataq_handle, errorInfo, my_data_1);

type = CA_VariantGetType (&my_data_1[0]); 

// returns 4198.

What does 4198 mean?

Thanks

Jeff

As you can see in the online help, CA_VariantGetType returns an enumerated type (defined in cviauto.h and starting from 100) OR'ed with either CAVT_ARRAY (defined as 0x1000) and/or CAVT_BYREF (0x2000), whichever applies to.

That is, your variant should contain an array of short integers (102 OR 0x1000).
