Code Crunching

Basically, this is a note to myself, but it may help you anyway. So, I publish it here.

Creating a little more complex query today, I got the error message "Insufficient key column information for updating or refreshing" when trying to apply changes to the data set.

Solution: Set CursorLocation to clUseServer and CursorType to ctKeySet.

Technology: ADO, SQL Server

During the recent days I was looking for a solution on how to access properties of my Wacom tablet within a Delphi application.

Using the Pen & Ink API of Windows is one possibility, however that offered much more than I needed, not thinking about the time getting into that one as well. On the Delphi-PRAXiS I found a link to Centaurix, a company offering an easy to use Delphi component, which gives me access to the properties I just needed. The component is freeware and comes with source code.

Great!
