HelpFile charge with busy led

Hi guys. In my app, I can load a help file that gives the word. But how to display an indicator busy before really be posted? The VI command line just invokes the command and does not expect or wait until it is closed (wait until completion = T). Example attached using the som LV chm file. Thank you.

Essentially, you will need to write a wrapper for system Exec. This wrapper VI would launch the help file with Exec System with "wait until the end" set to False. Then, after waiting a little short of time, you check to see if the Help window has demonstrated itself. If this is not the case, have the wrapper VI appear and enter a loop. The façade is simply a progress bar. In the loop you would keep control if the Help window has demonstrated itself. Once this is done, the VI wrapper may close itself.

A simple wrapper VI would be simply to change the cursor in the busy cursor, Exec System call and then enter the loop as described above. Once the window has been restoring the default cursor.

You can search the forum a lot of examples on the audit for windows and the change of the cursor.
