The method adds two integer numbers and returns the result. When the project properties window is opened, click Application tab, and then click Assembly Information button. In addition to making the DLL COM-visible, we also need to register the assembly as a COM component in the Windows registry.

On the Assembly Information window, check Make assembly COM-Visible. This allows COM-based applications to call the class library's member variables and methods. There are a few ways to do it based on your circumstances.

There is also a hack to Create an Additional VBA Thread.

The Performance Module contains: Are you sure you need VBA (Visual Basic for Applications) to solve your problem? Check out my Do you really need Visual Basic for Applications macro for that?

This will force you to explicitly declare the types of your variables.

VBA is a dynamic typed language therefore you do not normally have to declare the type of your variable or declare variables in that matter.

In some rare cases Excel may crash assuming that the Application is not responding. How to control when the Screen is Updated and when it is not? See the example below If you still aren’t satisfied with your VBA performance try Compiling your VBA to a . VBA code can be mulithreaded although this makes sense for macros running more than approx. When working on improving VBA performance you will certainly want to verify how some optimization will reduce your total execution time.

Net DLL in Visual Studio and use it inside MS Access, Excel VBA, or VB6 applications. Net) project and select Class Library as the template type. Below I created a simple calculation class for testing.

Hope the tips can save you a couple of hours or days of headaches. This class has two variable members and one Add() method.

When working with OLE objects remember that it is more efficient to declare the OLE object type explicitly.

Use: Use the With…End Clause when working with Object such as Ranges, Worksheets, Workbooks, Collections etc.
