PowerBuilder lets you trigger build and deploy operations
when you run or debug a .NET Web Forms or Windows Forms project.

By default, when you click the running man or debugging icon in
the PowerBuilder toolbar, or select Run from a project menu or context
menu for one of these target types, PowerBuilder determines if there
is a corresponding build directory for the selected target. If there
is, PowerBuilder checks whether the .NET modules in the build directory
are consistent with the latest changes to each object in your current
application.

If implementation
or interface changes are detected or if the build directory does
not exist for the current target, PowerBuilder displays a message
box that tells you the project is out of date and that prompts you
to redeploy the project. The message box has three buttons (Yes,
No, and Cancel) and a check box that lets you prevent the display
of the message box the next time you click or select run or debug.

If you click Yes in the message box, PowerBuilder builds the
project using an incremental or full rebuild�depending
on the current rebuild scope�and then redeploys it, using
the current project�s deployment specifications. If you
click No in the message box with the redeployment prompt, PowerBuilder
attempts to run or debug the currently deployed target even though
it is out of date. Clicking Cancel terminates the run or debug request.

If you select the Do not ask me again check
box and then click Yes or No, PowerBuilder modifies a
drop-down list selection on the General tab of the System Options
dialog box.
