  • you use designers instead of coding

Using a special component you can embed your code into event handlers of the built-in controls such as the Send button in Outlook, the Save menu item in Word, the Find command in Excel, etc. In addition, you can disable standard event handlers and completely replace them with your own ones.

Fact #8: Real keyboard shortcuts in all Office applications

  • you use designers instead of coding

Now, in one project, you can combine your add-ins, custom worksheet functions and MSForms controls to build very effective Excel-based solutions. Excel RTDS projects have a special module that implements the IRTDServer interface, contains RTD topic components and centralizes your applied code. The RTD Server module has its own designer.
