                           VFP 9.0 FIX - REPORT FOOTER

1. BUG:

     There is a report for test:

     Paper: A4 (21.0cm x 29.7cm)
     Print area: Whole page
     Page Header: Height = 5.0cm
     Detail: Height = 2.0cm
     Page Footer: Height = 4.7cm or 4.65cm

     The report print 10 records per page: 29.7cm = 5.0cm + 2.0cm x 10 + 4.7cm

     Please refer to the picture testreport.jpg:

     In vfp8, the report is correctly for all printers.

     Please refer to the picture testreport8.jpg:

     But in vfp9, there is some blank space between the detail and the page footer.

     Please refer to the picture testreport9.jpg:


2. CAUSE:

     We can calculate the top non-printable area for different printer:

     GetDeviceCaps(hdc,PHYSICALOFFSETY) / GetDeviceCaps(hdc,LOGPIXELSY) x 2.54

     For Epson LQ-1600K, the value is 0.846667cm.
     For HP LaserJet 1020, the value is 0.397933cm.
     For Adobe PDF, the value is 0cm.

     This value is equal to the blank space height.

     The BUG is the page footer have been added the top non-printable area.


3. RESOLUTION:

     We can write some code to fix the BUG.

     6, Recommend to add the following code to the start program:

     * VFP9FixReportFooter

     #IF ROUND(VAL(CHRTRAN(UPPE(VERSION()),"MICROSOFTVISUALFOXPRO","")),2)=9.0
     =f_vfp9fixreportfooter()
     #ENDI

     Now in vfp9, the report is correctly too.
