There are two functions for comparing VARIANT
s. One comes from the COM team, called VarCmp
. Assuming a successful comparison, it returns
Comparison | Return value |
---|---|
Less than | 0 = VARCMP_LT |
Equal to | 1 = VARCMP_EQ |
Greater than | 2 = VARCMP_GT |
This is consistent with the other VarXxx
functions.
On the other hand, the VariantCompare
function comes from the shell, and it returns
Comparison | Return value |
---|---|
Less than | −1 |
Equal to | 0 |
Greater than | +1 |
Yuck.
So be careful which one you’re calling and how you’re testing the result.
