I noticed that using the Launch Application component does not require a path to start a program ( ie. IEXPLORE.EXE ), but Start App service in the Application Interface component does require a full path in order to start the same program. This is not a problem, but I just wanted to let others know about it to avoid any frustrations.

Also, I am curious when the Application Interface component Keys service will be able to send a 'SPACEBAR' command. If a button is selected the spacebar is the Windows keystroke command to depress the button. The only way to accomplish a button press currently is to position the mouse over the button and send a left click command. Mouse positioning is not a problem, but if there are varying resolutions being employed by users the mouse placement is not consistent even when specifying mouse coordinates as 'normalized' via port 2 on the component.

Thank you Codemorphis.

I just noticed that I can press a button by sending a shifted ENTER command via Keys service in the Application Interface component.

My appologies.

Thanks for your post.

The "Launch Application" component is making use of the Path variable in your environment, which normally contains the path to the Windows directory. This is why typical applciations like Internet Explorer (iexplore.exe) can be launched without an absolute path.

The "Start App" service is normally used to invoke general applications rather than system applications which is why it was implemented without using the Windows system Path variable. This, however, could be a good option in the future.

Thanks for posting and providing your observations.
