Hello Alex,
Thank you for contacting National Instruments.
If you are asking how to make your VI appear like a native window box in Microsoft Windows, complete with menu bar (including a File menu option), the answer is to edit your VI's properties.
First, resize your front panel so that it displays everything the way you want it to. Then, click on File >> VI Properties and choose Window Appearance from the drop down box. You can then edit how your VI will appear when it is run. Use the customize option to fine tune your VI's look. In your case, however, I would recommend using the Top-level application window option. This option will make your VI appear most like a native window box.
I hope this answers your question. If not, let me know.
