Q118397: BUG: SETWINDOWCONFIG Returns an Invalid Configuration

Article: Q118397
Product(s): Microsoft Fortran Compiler
Version(s): 1.0,4.0
Operating System(s):

-------------------------------------------------------------------------------
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
