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)
