 Graceful exit from SolverSolve Solver loop found

Using Excel XP and Win XP

Just started using SolverSolve in a loop to solve a series of problems
(140 problems or 18 hrs).  Got it working OK and have just found a way
to gracefully abort the loop at the end of the current problem.  Could
not find this noted anywhere else and thought I might post it.  Still
have one problem that I could use help with that I will put in a
different thread.

Before I get to the sample, has anyone else made VBA edits in Excel
XP, closed the spreadsheet using the X in the upper right, and had the
sheet close without getting the "Do you want to save changes..."
screen to pop up?  I have but I can't seem to recreate it on demand
yet.  But it has made me mad at Excel XP a couple of times already (3
wks).  Some other bugs in there too, ain't there?

OK, I want to be able to close a loop containing a SolverSolve problem
gracefully at the end of the current loop (before the next problem
loads).  I had trouble with this because solver seems to swallow the
mouse during its operation.  But keys go through ok.  Note that this
will probably effect the Max. Iterations and/or the Max. Time popups.
But that is part of my problem in the other thread.

Hope this helps someone,

Make a form with two buttons.  I named these cmdStart and cmdStop.
You could get by with only one, but I wanted to be sure that Excel was
done opening the form, so the cmdStart button is really just a delay
to let Excel finish watever it has to do.

The code in the form looks like this:


Option Explicit

Private Sub UserForm_Activate()

    cmdStart.Visible = True
    cmdStop.Visible = False

End Sub

Private Sub cmdStart_Click()

    cmdStart.Visible = False
    cmdStop.Visible = True
    Call doIt

End Sub

Private Sub cmdStop_Click()

    MsgBox "The Clicks are swallowed by Solver :>( !"

End Sub

Private Sub cmdStop_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)

    MsgBox "But the KeyPress(es) aren't :>) !"

End Sub

Sub doIt()


        ' check if there are any more problems to do


        ' load the new problem

        SolverSolve UserFinish:=True

        ' unload the solved problem


End Sub
