I have a script in a custom toolbox which sums the values in a given field. After the user indicates which field (currently I have them typing it in but would love to know how to get the ArcToolbox to generate a dropdown after an input is identified) the script returns the value in a win32gui box.
Using win32gui means I have to install win32com package on the users machines. Is there another easier solution to return the value of sum-ing the values in a field..preferably if the dialogue box lets you copy the text with the mouse?
I am using ArcGIS Desktop 9.3.
