General COM question

[smakadia]

As a VC++ developer, I've created COM components that are used by clients developed using VC++. But now I'm developing a COM component, in VC++, that will be accessed by a VB client. I've got interfaces whose parameters are of basic data types such as unsigned char, unsigned short, char (string), int, double, etc... Is it better to use a VARIANT data type instead of the basic data types? Is there an equivilant to the unsigned (type) data type in VB? Currently a VB client will use this component but in the future, who knows, it could be Java, VBScript, JScript, C#, etc...? Thanks for any help you can give.

Please rate my post if you think it was helpful. Or you can send money!

If you use the automation data types, your code will be accessable by any language that supports them (VC++, VB, VBScript, JScript, JavaScript, Java, WSH COM objects, etc.).

Hope this helps.
