  • What is your most useful C/C++ snippet?

    - by maddizzyro
    Hello all, It seems that every project has an "util" module with various code snippets used throughout other files and which don't fit any particular pattern. I want to improve my "util" library, so please post here the most useful class / function / macro that you use in all your C/C++ projects. Please keep the entries small (under 100 lines) and give only one example per post. Thank you.

  • Autopopulate from Select box from database

    - by Chris Spalton
    hope you can help, please forgive any poor coding or anytihng, I'm new to this and just hacking my way through to get things to work. That said, on one of my projects I have this code, which successfully populates the dropdown from a database when the page is loaded: <select name="Region" id="Region"> <option value="">-- Select Region --</option> <?php $region=$POST['Region']; if ($region); { $regionquery = "SELECT DISTINCT REGION FROM Sales_Execs "; $regionresult = mysql_query($regionquery); while($row = mysql_fetch_array($regionresult)) { echo "<option value=\"".$row['REGION']."\">".$row['REGION']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Region').value = <?php echo json_encode(trim($_POST['Region']));?>; </script> </select> On my next project that I'm working on now, I need to do the same thing, so I copied the above code amended, and placed in my new project: <select name="Sales_Exec" id="Sales_Exec"> <option value="">-- Select SE --</option> <?php $salesexec=$POST['Sales_Exec']; if ($salesexec); { $salesexecquery = "SELECT DISTINCT Assigned FROM Data "; $salesexecresult = mysql_query($salesexecquery); while($row = mysql_fetch_array($salesexecresult)) { echo "<option value=\"".$row['ASSIGNED']."\">".$row['ASSIGNED']."</option>\n "; } } ?> <script type="text/javascript"> document.getElementById('Sales_Exec').value = <?php echo json_encode(trim($_POST['Sales_Exec']));?>; </script> </select> This second chunk of code doesn't work... and I can't work out why as it seems I've copied it all and amended all the neccersary parts, can anyone spot what is wrong? Thankyou!

  • 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?

  • UIView fine for iPhone 4in, but squashed in iPhone 3.5in

    - by coopersita
    I started a new project in the new Xcode, and I see that my default the main window is set to 320x548. I'm fine with that, but when I test my app, a view I added to my main xib, which is supposed to be 280x280, looks more like 280x200 when testing on 3.5in devices. I've tried changing the settings for that view in the xib, but nothing seems to affect it. How do I ensure background compatibility so that in older devices the view is the same size?

    - by Maciej

I wonder if exists a bit simple way to archive that (eg by passing URL to setup.exe or such) ? EDIT This Might be also interesting: http://www.codeproject.com/KB/aspnet/Add_Custom_Prerequisite.aspx?msg=2520811 will check and let you know...

  • Getting started with PHP on Windows

    - by jamesaharvey
    I'm getting started with a side project that will be developed using PHP and I'm looking for guidance on getting my Windows machine up and running and ready for development (as quickly as possible). Being that PHP development is more geared towards Linux users/developers (which I am not), I'm trying to figure out how to get all the pieces in place to get a 'WAMP' stack operational locally on my Windows machine. Any good tutorials/quick start guides out there and if not, does someone have all the steps that they could provide me with here?
