VBA to lock a workbook to a certain width and height

After searching for 2 hours online, I have read virtually most of the articles and have come to the conclusion that it may be impossible to lock an Excel workbook to a certain window size.

What I am trying to do is drag the bottom right corner of a workbook window to a desired width and height, and punch in some VBA code [may require API calls] and the outcome I desire is to have that window locked to that size and prevent other users from resizing it.

If there is a solution to this, then you walk in the pathways of the righteous Excel beings.

Thanks for your reply. Well, I can achieve the specific sizing if I were to use a userform for an item that I am working however I am using a worksheet in a workbook and my 'app' interface occupies an area of A1:K31. On opening the file I wanted the viewable area to only be the range of my app as it already looks like an app and prevent users from resizing it because it will lose its 'appiness' look.

I tried this but it doesn't work with what I want to achieve. Maybe this is one of the things VBA and Excel cannot do.
