Question

I’ve compiled C# code into a DLL, but have little experience with them. My C# code contains a class HelloWorld with a static method Print(). I’d like to use this DLL in VBScript to call the method Print(). I know this is base, but I’m using this as a test for a larger scale project that will be compiled to DLL in the end. What’s the declare look like for that and how would the method call look?

Important: Both methods will work only if the DLL exposes a COM interface.

If your dll is registered with the system, use CreateObject with it’s ProgID.

Set myObject = CreateObject("MyReallyCoolObject.HelloWorld")
myObject.Print

If your object is not registered on the system, use GetObject with a path to the file containing your object. Make sure your object exposes the proper interface. (The second parameter is optional. Here you can provide a class name if your object exposes more than one.)

Set myObject = GetObject("C:\some\path\helloworld.dll", "appname.HelloWorld")
myObject.Print
