    High Pass Dialog Textbook Exercise

    ojodegato Level 1

      I purchased the Power, Speed and Automatitation textbook to learn Photoshop Scripting. I am working through the exercises in the last chapeter Building Custom Dialogs and have stumbled on the last exercise building a High Pass Dialog. When I test the script ai get a time run error which I am not able to track down. Can someone please look at the script and let me know where the error is coming from.

      Many thanks,







      This dialog gathers data for creating a High Pass layer,

      which can shapern or blur a docuemnt.


      This dialog shows the use of many differnt types of UI controls




      Stage #1 build the dialog

          Create helloWorldDialog() function

              Place the dialog where it will be displayed

              Add UI elemtnst to function

              Add a group box panel for formating the buttons in a row

              Add On and Cancel buttons


          Create initHelloWorldDialog() function

              Initalize buttons OK and Cancel

              Add Events to OK and Cancel buttons



      Hook up the dialog to respond to events (add to SET UP)



      Stage #2 display the dialog

          Create runHelloWorldDialog() function



      Stage #3 process the results

          processHelloWorldResults() function

          show alert()




      Script Installation:

      1.Mac place script in Applications/Adobe Photoshop CC/Presets/Scripts

      2.Windows place script in C:\Program Files\Adobe\Adobe Photoshop CC#\Presets\Scripts\

      3.Restart Photoshop

      4.Choose File > Scripts > template





      // SET UP




      //Enable double clicking from hte Macintosh Finder or Windows  Explorer

      #target photoshop



      //Make Photoshop the formost Appplication




      //** DIALOG STAGE #1 - build the dilaog **



      //Create the dialog object and its UI objects

      var theDialog = createHighPassDialog();



      //Hook up the dialog to respond to events

      initHighPassDialog (theDialog);






      // MAIN




      //** DIALOG STAGE #2 - display the dialog **

      if (runHighPassDialog(theDialog) == 1) {


          //User pressed OK


          //** DIALOG STAGE #3 - process the dialog results **
