问题 I need to programmatically change the background color for a single row in a datagrid in Flex. I've scoured the Net and found reference to "dg.setPropertiesAt," which is not a supported method (according to the compiler). Also, there are suggestions to extend the dg's "drawRowBackground" method but I need to set the background externally (not from logic inside the dg). Any and all suggestions welcome. TIA, Bob 回答1: You'll have to use an itemRenderer in order to accomplish this. See the

问题 I want to have a condition incase the row doesn't exist at all. $stmt = $conn->prepare('SELECT * FROM table WHERE ID=?'); $stmt->bindParam(1, $_GET['id'], PDO::PARAM_INT); $stmt->execute(); $row = $stmt->fetch(PDO::FETCH_ASSOC); Tried if (count($row) == 0) and if($stmt->rowCount() < 0) but none of them works. 回答1: You can just check the return value directly. $stmt = $conn->prepare('SELECT * FROM table WHERE ID=?'); $stmt->bindParam(1, $_GET['id'], PDO::PARAM_INT); $stmt->execute(); $row =

问题 I have a pandas data frame like this: Column1 Column2 Column3 Column4 Column5 0 a 1 2 3 4 1 a 3 4 5 2 b 6 7 8 3 c 7 7 What I want to do now is getting a new dataframe containing Column1 and a new columnA.

Any advice would be helpful. Thanks in advance! 回答1:

问题 If there was just one value in a row. I got the answer but i have more than one. This my main class which i couldnt decide how to fill Textwatcher stuff. "CityArray" is the class which i created the rows and "CityXmlParse" is the class that i take data from XML file called "cities.xml" in the raw folder. Each row has an image and a name and i want to filter the rows by name while typing, but whole row must be seen after typing (with image). public class TravelFinalActivity extends Activity {

问题 I'm having problems implementing a table row that allows text to wrap to multiple lines, and also has an image on the left, and a disclosure accesssory on the right. The multiline text is fine but the imageView expands to the right when there is more than one line of text. I want images in all rows to be the same size. I've tried setting the autoresizingMask to UIViewAutoresizingNone but this doesn't seem to work.. Do I need to use the contentView, or a nib file? Any help/example code

问题 I am working on PHP & mySQL based website. I am trying to setup the 'Settings' page in administration panel where I can enter different settings to manage the site. The settings can range upto 100 (or even more) depending upon the requirements. So instead of making 100 columns (and increase if I have to add more columns in future), I want to store the data in row wise format and fetch the values as if I am fetching it from columns.
