separator

问题 I am using MySQL fulltext and PHP (codeigniter) to search a database containing RSS items. Problem is some of these items's titles use underscores instead of spaces. Since MySQL considers underscores as part of a word, these items will never be matched in the search, unless the user types the exact title including underscores. Server is shared so I don't have access to MySQL Server System Variables. Can this behavior be changed in some other way? Can this maybe be done through the search

问题 I need to make a grouped table view with custom cells. Each cell must have a background image, so that image of one cell will touch the image of the second cell and so on. I've tried to set the separatorStyle to None, but I still get the transparent separator between cells. Help me, please, remove this space between cells. Have a good day, Thanks! 回答1: I found that when I set the background image, the separator went away automatically. The problem is that I want it to show up. Here's what I

问题 How I can remove datetime separator and time separator in date select create by gem called simple_form ?

问题 When using writetable() to write a Data Frame to a file, I would like to be able to have the delimiter be a space then a comma (i.e. " ," as the delimiter). I know writetable() only has the option to have a single char as the separator argument. Is there a possible workaround to be able to have a string as the delimiter? Or, is it possible to simply add a space after every single data point in the data frame and then output it as normal to a .csv file, therefore essentially having the " ,"

问题 I use the MPFR library to do calculations on big numbers, but also return a double with 8 digits after the decimal point. I mpfr_sprintf the number to a char array so precision or anything isn't lost. Everything is fine except that I didn't find any thousand separator option in the documentation(or I missed it). Given a number such as 20043.95381376 I would like to represent it like 20,043.95381376 for better readability. Or the number 164992818.48075795 as 164,992,818.48075795 I read about

问题 I must process some huge file with gawk. My main problem is that I have to print some floats using thousand separators. E.g.: 10000 should appear as 10.000 and 10000,01 as 10.000,01 in the output. I (and Google) come up with this function, but this fails for floats: function commas(n) { gsub(/,/,"",n) point = index(n,".") - 1 if (point < 0) point = length(n) while (point > 3) { point -= 3 n = substr(n,1,point)"."substr(n,point + 1) } sub(/-\./,"-",n) return d n } But it fails with floats. Now

问题 On Windows platform, with the VCL , when we want to add a separator in a menu, we add a TMenuItem with a Caption := '-' ; With FireMonkey , we add a TMenuItem with a Text := '-' ; It works as expected on Windows platform, the item with the Text='-' is displayed as a separator. But, when I run the same application on OSX , I have the minus sign visible... I haven't found any property on the TMenuItem to specify it is a separator ... I have tried with a TMainMenu and a TMenuBar ( UseOSMenu :=

问题 I have made a custom button bar as described here. Now, I want to add a separator between the first and the second and between the second and the third button. My button bar is defined as follows: <LinearLayout android:id="@+id/buttonBar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/buttonbarstyle" android:layout_alignParentBottom="true" android:orientation="horizontal" > <ImageButton android:id="@+id/buttonBarImageButton1" android

问题 I want to display a very simple separator in my listview. I have made a custom adapter that extends 'SimpleAdapter' and my implementation works somewhat. It displays the dividers and my list correct but once I start to scroll and then scroll back up the dividers gets messed up, placed instead of listitems etc. Sometime when I scroll some more it will look correct again. This is my code for 'getView' @Override public View getView(int position, View convertView, ViewGroup parent){ if(((String
