3. Enter the following code in the btn_ep function of the event procedure by using the source code editor:
  object->setProperty(WSNlabelString,"Hello!");
  
  Figure: Window displayed after this addition is made with the source code editor
  
  If Java is the language used, add the following code in the btn_ep function:
  object.setProperty("labelString","Hello!");
2.7 Building and Running an Executable File

This section explains the procedure for creating and running an executable file.

Procedure
1. Build the file from the [Project...] menu.
  If an error message is displayed in the [Console] view, take action according to the error message contents to correct the error.
  To build the file, select [Clean] from the [Project...] menu, and run "build."
  The build processing after you select [Clean] varies as follows:
  - If [Build Automatically] is checked on the [Project...] menu, the build starts automatically.
  - If [Build Automatically] is not checked on the [Project...] menu, check [Start a build immediately] in the [Clean] dialog box, and click [OK].
