TITLE   :BUG: SETWINDOWCONFIG Returns an Invalid Configuration
PRODUCT :Microsoft Fortran Compiler
PROD/VER::1.0,4.0
OPER/SYS:
KEYWORDS:kbcode kbFortranPS kbLangFortran

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Fortran Powerstation 32 for Windows NT, versions 1.0, 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

The SETWINDOWCONFIG() function does not create a valid window configuration
record. The second call to SETWINDOWCONFIG() fails, even though the online Help
says that SETWINDOWCONFIG() is supposed to modify the window configuration so
that the next call will succeed.

RESOLUTION
==========

Each time SETWINDOWCONFIG() is called and fails, it makes adjustments to the
window configuration record. If SETWINDOWCONFIG() is called enough times, it
will eventually succeed.

NOTE: Under FORTRAN PowerStation 32, version 4.0, the call to SETWINDOWCONFIG()
never succeeds.

STATUS
======

Microsoft has confirmed this to be a bug in the products listed at the beginning
of this article. We are researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION
================

To demonstrate this problem, compile and run the sample code below. Both the
first and second calls to SETWINDOWCONFIG() generate a window configuration
record that is not consistent. For example, the number of pixels needed in X
(106) does not equal the number of text rows (13) times the row width (8). Even
with these inconsistencies, the third call does succeed.

Sample Code
-----------

   C compile options required: /MW or /MWs

         include 'flib.fi'
         include 'fgraph.fi'
         include 'flib.fd'
         include 'fgraph.fd'

         record /windowconfig/ wc

         wc.numxpixels=-1
         wc.numypixels=-1
         wc.numtextcols=1
         wc.numtextrows=1
         wc.numcolors=-1
         wc.fontsize=-1

         print *, 'Success? ',setwindowconfig(wc)
         print *, 'numxpixels',wc.numxpixels
         print *, 'numypixels',wc.numypixels
         print *, 'numtextcols',wc.numtextcols
         print *, 'numtextrows',wc.numtextrows
         print '(A,Z8)', ' Font size: ',wc.fontsize
         print *, 'Success? ',setwindowconfig(wc)
         print *, 'numxpixels',wc.numxpixels
         print *, 'numypixels',wc.numypixels
         print *, 'numtextcols',wc.numtextcols
         print *, 'numtextrows',wc.numtextrows
         print '(A,Z8)', ' Font size: ',wc.fontsize
         print *, 'Hit return to continue'
         read *
         print *, 'Success? ',setwindowconfig(wc)

         END
