Why Can't I Find My VI in My Library File (LLB) When I Try to Build an Application?

Primary Software: LabVIEW Development Systems>>LabVIEW Full Development System
Primary Software Version: 6.0
Primary Software Fixed Version: N/A
Secondary Software: N/A

I created a VI Library File (LLB) using Save with Options»Development Distribution. Now, I am trying to build an application out of the main VI in that LLB. However, when I go to the Source Files tab of my Application Builder and choose Add Top Level VI, only my subVIs are listed. How can I find my main VI?

You can see your main VI by choosing View All instead of Custom Pattern.  Because of the way your LLB was created, you can't see your main VI is because it was saved without the .vi extension. Whenever you go to create an LLB using Save with Options»Development Distribution, you need to have already saved your main VI. If you haven't saved your main VI already, using Save with Options»Development Distribution, will still create the LLB, but your main VI will be saved without the .vi extension. This is what prevents you from seeing the main VI when you try to build an application. 

If you have the Professional Development System of LabVIEW 6.x, you can rename your VIs with the VI Library Manager. If you have the Full or Professional Development System of LabVIEW 5.x, you can rename your VIs with the File Manager. The VI Library/File Manager allows you to look inside of your LLB to rename VIs, copy VIs, convert LLBs to directories, and vice versa. To launch the VI Library Manager in LabVIEW 6.x go to Tools»VI Library Manager. In LabVIEW 5.x go to Project»File Manager.

NOTE: To mark a VI in your LLB as top level, go to File»Edit VI Library in LabVIEW 5.x, or Tools»Edit VI Library in LabVIEW 6.x and higher. The top level VI will always show up at the top of your LLB.
