Title: Blurcalc
Post by: claygrazer on March 11, 2016, 12:16:06 PM
For us OLD folks that use Bob's old Blurcalc program on XP 32 bit machines, it is a joy.  I've not found anything else like it online.  It would be nice to have a concise source that gives the formulas used in the old Visual Basic Blurcalc program.  If available, they could be put into a newer program for our Bokeh enjoyment.
Glad to be part of the Community!

As far as I know there is nothing like it anywhere online!

My solution to the issues of upgrading my OS form XP 32-bit to Win7 64-bit was to install the Microsoft Virtual (XP) Machine, which emulates a 32-bit Windows XP system, then run Blurcalc (and a bunch of other older programs that don't work with Win7 64bit) on the Virtual Machine. It works well and allows me to use quite a few older programs that I could never get to work on Win7 64-bit.

You can find the Virtual Machine at http://windows.microsoft.com/en-us/windows7/install-and-use-windows-xp-mode-in-windows-7

It's pretty unlikely I'll ever get around to updating Blurcalc or Dofcalc to work on Windows 7/8/10 64-bit systems. It might happen, but I wouldn't hold my breath for it.
