• Any way for linq query to check against existing select?

  - by danrhul

  I have an an offer, that can be in any number of categories. I don't however want that offer to then appear twice or however more. I was wondering if its possible to have a where clause that ascertains whether that offer already exists in that select statement and if so obviously to ignore it. Here is the linq query: Offers = from o in offerCategories orderby o.RewardCategory.Ordering, o.Order where o.RewardOffer.IsDeleted == false select new OfferOverviewViewModel { Partner = o.RewardOffer.Partner, Description = String.Format("{0} {1}", o.RewardOffer.MainTitle, o.RewardOffer.SecondaryTitle), OfferId = o.OfferId, FeaturedOffer = o.RewardOffer.FeaturedOfferOrder.HasValue, Categories = from c in offerCategories.Where(oc => oc.OfferId == o.OfferId) orderby c.RewardCategory.Ordering select new CategoryDetailViewModel { Description = c.RewardCategory.DisplayName } },

• How do I most efficienty check the unique elements in a list?

  - by alex

  let's say I have a list li = [{'q':'apple','code':'2B'}, {'q':'orange','code':'2A'}, {'q':'plum','code':'2A'}] What is the most efficient way to return the count of unique "codes" in this list? In this case, the unique codes is 2, because only 2B and 2A are unique. I could put everything in a list and compare, but is this really efficient?

• What's wrong with my If-statement to check uploaded file? (PHP)

  - by ggfan

  I am trying to test if the uploaded file is the image type I want. If it isn't a gif,jpeg, png, it should echo "Problem". But when I execute this code, it always says there's a problem. What's wrong with my if statement? $uploadfile_type=$_FILES['userfile']['type']; if ( ($uploadfile_type !='image/gif') || ($uploadfile_type !='image/jpeg') || ($uploadfile_type !='image/png')) { echo 'Problem: file is not a gif or jpeg or png!'; exit; } This code works when I am only checking one type of image. Ex: if($uploadfile_type !='image/gif') -- this statement would work but when I add a OR it doesn't.

• How to check in which position (landscape or portrait) os the iPhone now?

  - by Knodel

  I have an app with a tab bar, and nav controllers in each tab. When user shakes the device, a UIImageView appears as a child view in the nav controller. But the UIImageView must contain a special image, depending on the device's current orientation. If I write just - (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) if (interfaceOrientation == UIInterfaceOrientationPortrait|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { //Code } else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight||interfaceOrientation == UIInterfaceOrientationLandscapeLeft) { //Code } } The view just goes crazy if user rotated the device before shaking. Is there a method to get iPhones current orientation?

• check for null date in CASE statement, where have I gone wrong?

  - by James.Elsey

  Hello, My source table looks like this Id StartDate 1 (null) 2 12/12/2009 3 10/10/2009 I want to create a select statement, that selects the above, but also has an additional column to display a varchar if the date is not null such as : Id StartDate StartDateStatus 1 (null) Awaiting 2 12/12/2009 Approved 3 10/10/2009 Approved I have the following in my select, but it doesn't seem to be working. All of the statuses are set to Approved even though the dates have some nulls select id, StartDate, CASE StartDate WHEN null THEN 'Awaiting' ELSE 'Approved' END AS StartDateStatus FROM myTable The results of my query look like : Id StartDate StartDateStatus 1 (null) Approved 2 12/12/2009 Approved 3 10/10/2009 Approved 4 (null) Approved 5 (null) Approved StartDate is a smalldatetime, is there some exception to how this should be treated? Thanks

• PHP: What's the best way to check equality of $_SERVER['HTTP_REFERER'] ?

  - by Hank

  I have a PHP script that checks the HTTP Referer. if ($_SERVER['HTTP_REFERER'] == 'http://www.example.com/') {...} However, this seems inherintly unsafe ... because what happens if the user goes to 'http://example.com/' or 'http://www.ExaMple.com' (both of which don't match the equality test). Question: what's a better equality test to ensure that the HTTP Referer is coming from 'example.com' ?

This does not happen always, but after some time of running said program (lowRange varies each time the function is called) What am I not seeing?

• How to check an exectuable's path is correct in PHP?

  - by nickf

  I'm writing a setup/installer script for my application, basically just a nice front end to the configuration file. One of the configuration variables is the executable path for mysql. After the user has typed it in (for example: /path/to/mysql-5.0/bin/mysql or just mysql if it is in their system PATH), I want to verify that it is correct. My initial reaction would be to try running it with "--version" to see what comes back. However, I quickly realised this would lead to me writing this line of code: shell_exec($somethingAUserHasEntered . " --version"); ...which is obviously a Very Bad Thing. Now, this is a setup script which is designed for trusted users only, and ones which probably already have relatively high level access to the system, but still I don't think the above solution is something I want to write. Is there a better way to verify the executable path? Perhaps one which doesn't expose a massive security hole?
