SUMMARY
This article shows how to display the Microsoft Word for Windows 97 print dialog box that always remains on top of all windows or applications without making Word visible.
MORE INFORMATION
One problem encountered when you open Word's print dialog box from Visual FoxPro using OLE automation and do not show Word or the document window is that the following message may appear:
This usually occurs because Word's print dialog box appears behind the current window. To prevent this message, use the FindWindowA and SetWindowPos Application Program Interface (API) calls to make the print dialog box remain on top.
Sample Code
***** Begin code sample *****
DECLARE LONG FindWindowA IN WIN32API ;
STRING class, ;
STRING title
DECLARE SetWindowPos IN WIN32API ;
LONG HWND, ;
LONG hwndafter, ;
LONG x, ;
LONG y, ;
LONG cx, ;
LONG cy, ;
LONG flags
oWord = CREATEOBJECT("Word.Application" )
oWord.Documents.Add
* Check background printing.
lBackground = oWord.Options.PrintBackground()
IF lBackground
oWord.Options.PrintBackground = .F. && Turn off.
ENDIF
dlg = oWord.Dialogs(88) && Open Print dialog box in Word.
dlg.SHOW
* Get the window handle to Word 97.
wordhandle = 0
DO WHILE wordhandle = 0
* Pass the class name for Word 97 "OpusApp" to FindWindowA
wordhandle = FindWindowA("OpusApp", NULL)
ENDDO
* Variables used in the SetWindowPos API.
swp_nosize = 1
swp_nomove = 2
hwnd_topmost = -1
hwnd_notopmost = -2
* Call SetWindowPos to make the print dialog stay on top.
lretval = 0
lretval = SetWindowPos(wordhandle,hwnd_topmost,;
0,0,0,0,swp_nosize+swp_nomove)
* Turn on background printing if it was on before.
IF lBackground
oWord.Options.Printbackground = !oWord.Options.Printbackground
ENDIF
oWord.Quit
RETURN
***** End code sample *****
NOTE: On some machines, Word displays briefly and disappears whenever the print dialog box closes.
