How are you?
If you please i'm writing c# code to make a tool addin and i don't know to change the mouse cursor when click the tool.
(Ex. like zoom tool when i click on it mouse cursor change to magnifier).
During the stage of when you create the Tool Addin in the Wizard in Visual Studio you can define the cursor that will be used when the tools is activated. Look at this page for more advice. Look at step 6 in Using the ArcGIS Add-Ins Wizard you can see an option for setting the cursor.
