Here are mine:
- DevExpress VCL Subscription. Pretty expensive but worth a lot more. I', still amazed about how great a value they deliver to a developer. Grids are fantastic. Editors, skinning. all. Support is great.
- REMObjects SDK. I love the way I can break the functionality of a big project into a few of smaller ones and then exchange the data between them in many ways. Without using packages which I always try to avoid.
- TMS Smooth controls for the makeup.
- SecureBlackBox SSL not to rely on third party dlls, but get SSL functionality with full source code.
- FastReports, inexpensive and a great reporting tool. Regularly updated.
- Addin_express for creating Microsoft Office addins. I'm using it in my next project. it works on all versions of MSOffice.
