Handling Decimal Type? 1

[Glenn9999]

I've been working with an ActiveX interface which has a type of "Decimal" in the original function prototype.

The type library converter helpfully called it "OleVariant", but I'm not having any luck getting any data out of it..

Any help would be appreciated.

care to say which interface?

IUpdate.MinDownloadSize for one example. I have it returning other "familiar" data types out of that interface, so I'm not having a problem there. It's just that "OleVariant" seems to not be doing the job (in some way) to return what I need. Like was said, the variable that this returns is called "Decimal" in the original interface headers.

This is the thing that comes up that seems closest to what it's looking for, but I'm still not sure that's correct.

Perhaps try type casting to a double or use VarAsString and then cast it to a double.

Got it figured out (somewhat by chance, but figured out just the same). Turns out, the redefinition of values really wasn't warranted as it actually was returning a static Delphi TDecimal.

I ended up doing:

var
  test: OleVariant;
  test_out: Double;

test := MyUpdate1.MaxDownloadSize;
VarR8FromDec(@test, test_out);

I'll probably write a function to do this since I have many values like this I will want to access as I get further along in the project I'm working with.
