Hi Agraham
Thanks for your reply.
I know what modules are all about and how they work. It is just that I got my sentences mixed up. It is sometimes difficult to think in german and write in another language!

I am not really sure that you understand what I want to do. I am busy with a "Polar" calculation, but for the angle input textbox, I need to add 2 angles. Now,.....the angle input textbox has the focus and I click on the "Calculator" icon to add the 2 angles. Then I click on ">>" on my calculator; the calculator closes (hides....or whatever you want to call it!

and hey presto the answer sits in the input textbox that had the focus. This way I don't have to write the answer on my hand in the field. If I carry on like this I will get blood poisening!
While I have your attention. May I send through my (yours

) delauney module. I need to me able to delete triangles and also add "Manually" triangles by tapping on points on the screen. You will also see that I have a "Shading" routine. But it does not work very good. Maybe you can give me some ideas.
And lastly. I am nearly finished with my CAD module. Works very much like Autocad Lite. If I send it through could you have a look to put it in a DLL?
Thanks
