ReportPro - Tabs

[ecosSystem]

If you print a memo-field with the following content (chr(9) between the blocks):

1234 5678 abcde 1234 5678 abcde

RP prints 5678 abcde too high:

This happens with normal text and with RTF-text and worked fine in the VO-Version. This bug is caused by the function rpTabbedTextOut in Drawtext.prg Please replace the line MoveToEx(sDrawText:hDC,nX,sDrawText:nY-sDrawText:nDescent,NULL_PTR) with MoveToEx(sDrawText:hDC,nX,sDrawText:nY,NULL_PTR) This fixes the behaviour.

A second problem concerns only RTF-text. If the text after the first tab is marked as bold, RP goes completely nuts:

I did not find a solution for this yet, this didn’t work in VO either. If you find a solution please let me know. I will also try to figure it out when I find some time.

This should fix both problems:
