Object Comparisons

[Eiredrake]

I'm in a class....

and I'm accepting an argument that is an object which is to be processed. However if it's anything other than the type of object I'm expecting (another class) obviously I'm not going to be able to pull the data off of it that i need to process.

You can't do this...
if object1=typename then

Because it says that the type is a type in System.Types and can't be used in an expresion.

So, my question is, how do you compare objects?

You can use getType, TypeName, or probably IS ObjectType.

Wouldn't it be easier to just make the parameter the class/object you are expecting instead of the generic object?

The GetType method might work for you: Object.GetType

I stumbled across the IS operator. Thanks


Actually... the problem is that I don't know what the object is before I get it. I'm storing a serialized object in the Dbase because it will hold information access information for a service. One service may require, domain name/username/password, another may require just username/password... yet another may require nothing at all.

That's actually what I'm testing for... to make sure the object ISN'T a generic object but is actually a previously defined service class.


Personally I think this is all stupid the way my boss wants this done. We're basically turning a relational database into an object oriented one just because he doesn't know what he wants to store. <sigh>

what you want to do is creat to subs/function of the same name..but differnt parameters...the program will know which one to run


public sub login(name as string, username as string, password as string)

public sub login(username as string, password as string)

public sub login(username as string, password as string)

Don't forget to use the Overloads keyword.

Public Overloads Sub login(name as string, username as string, password as string)

Public Overloads Sub login(username as string, password as string)

Do you use the overloads keyword Sheppe? I never do, maybe thats bad I don't know, but I just skip it. I did the same thing with the Call keyword in VB6. As long as none of them use the Overloads keyword it'll still work.
