  • Firebird 2.1 + EXISTS = query bug?

    - by Atlas
    Using Delphi 2009 + Firebird 2.1.3. Database is ODS 11.1, default char set is UTF8. My prepared query is as follows: SELECT a.po_id, a.po_no FROM purchase_order a WHERE EXISTS (SELECT 1 FROM sales_order_item z1 JOIN purchase_order_item z2 ON z2.so_item_id = z1.so_item_id AND z2.po_id = a.po_id WHERE z1.so_id = :soid) ORDER BY a.po_no Now when I loop this say 1000 times because I have 1000 x so_id, the CPU usage get at 100% for FBSERVER.EXE Anyone encountered this problem?

  • Why is graphical emacs so ugly?

    - by Michael Gummelt
    Every hacker I know uses terminal emacs. Graphical emacs is hideous. The default text is huge and out of place, and the borders are much bigger and blockier than in any other application. Everything I've read about switching the font is confusing and completely different than the font selection used by other applications (I'm on Ubuntu). Does anyone actually use graphical emacs (vs -nw)? If so, how do you make it bearable?

  • Get gprof to profile based on wall-clock time?

    - by jetwolf
    My understanding is that by default gprof takes into account CPU time. Is there a way to get it to profile based on wall-clock time? My program does a lot of disk i/o, so the CPU time it uses only represents a fraction of the actual execution time. I need to know which portions of the disk i/o take up the most time.

  • User control disapear when added to a Panel

    - by dutt
    I've got a user control class that works fine, drawing, events firing and the works. When i programmaticly add it to a class that extends from Panel it disapears. I've checked around and the line that makes it disapear is the line where i go panel.Controls.Add(myuserControl). Without that line the control works just fine, does anybody know why it won't show after the add? I'm currently doing the painting of the user control by overriding OnPaint, but the panel is using the default painting.

  • vim - open file with complete path

    - by David Oneill
    If I have a file that contains a complete path for a file, is there a way to highlight the filename (using visual mode) and open the file? (preferably in a split screen) As I think about it, here is what I would like: if the file name contains a / character, assume it is a full path (IE the 'current directory' is root). Otherwise, use the current folder (IE default behavior) Is this possible?

  • Highlight table view cells when user drags across rows

    - by chronos
    I have a grouped table view that does not need to scroll. I'd like each cell to highlight as the user moves their finger down the screen and call didSelectRowAtIndexPath on release. This behaviour can be seen done by apple in 'settings mail add account'? I can't seem to replicate it myself, all I can get is the default, where the cell deselects as soon as the user moves their finger.

  • Should I name my solution files in lowercase for SEO?

    - by Scott
    I read that an SEO best practice is to use lowercase urls. Should I name my asp.net webforms project files lowercase as well? Visual Studio doesn't name default documents in new projects all lowercase. I'm not sure it matters since browsing to http://www.mysite.com/mypage.aspx will still work even if your page is named MyPage.aspx. Can somebody enlighten me on this?
