format

问题 I have a iFrame tool, which should get rendered in a other format than my page. So I want to detect requests from iFrame like I can detect them from a iPhone. Is this possible? Is there a special hint in the request header, that I could use, or could I manually enter one? Thanks Markus 回答1: When you get a request from an iPhone there will be send a "User Agent"-String like Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543a Safari/419

问题 Do you know how can I set the thousand sepator and have a value formatted like this? 403.000 I'm using apache-poi 3.8 with Java. I googled it a lot but I didn't find an answer. I can't use a string value because my formulas are not evaluated correctly in this way. Any help? thanks! I've tried something like this: cellStyle.setDataFormat(creationHelper.createDataFormat().getFormat("#.##0")); but it doesn't work.. 回答1: You can do this: final HSSFCell dataCell = dataRow.createCell(1); dataCell

问题 I need to format a number with a specifc mask: 9.9.9.9.99.999 , depending on the length of number string. For example: - 123456789 => 1.2.3.4.56.789 - 123456 => 1.2.3.4.56 - 1234 => 1.2.3.4 - 123 => 1.2.3 - 12 => 1.2 It will not occur a number string with 7 or 8 digits in the input. How could that be implemented with regex, preferably in python? Thanks in advance. 回答1: You can use this pattern: (?:(?<=^\d)|(?<=^\d{2})|(?<=^\d{3})|(?<=^\d{4})|(?<=^\d{6}))(?=\d) with . as replacement. example:

问题 I'm just coming up to speed with Python and had a question about best practices (or at least common practices) around using .format on a string. My question is mostly around when you would use blank curly brackets vs. an index number vs. a name. For example if you had a single variable that you wanted to include in a string which one would you do? print "I {} Stack Overflow".format(var) print "I {0} Stack Overflow".format(var) print "I {verb} Stack Overflow".format(verb = var) Does this

问题 Let's say I have a list datalist , with len(datalist) = 4 . Let's say I want each of the elements in the list to be represented in a string in this way: s = "'{0}'::'{1}'::'{2}' '{3}'\n".format(datalist[0], datalist[1], datalist[2], datalist[3]) I don't like having to type datalist[index] so many times, and feel like there should be a more effective way. I tried: s = "'{0}'::'{1}'::'{2}' '{3}'\n".format(datalist[i] for i in range(4)) But this doesn't work: Traceback (most recent call last):

问题 This code launches ping: $ProcessInfo = New-Object System.Diagnostics.ProcessStartInfo $ProcessInfo.FileName = "ping.exe" $ProcessInfo.RedirectStandardError = $true $ProcessInfo.RedirectStandardOutput = $true $ProcessInfo.UseShellExecute = $false $ProcessInfo.Arguments = "localhost" $Proc = New-Object System.Diagnostics.Process $Proc.StartInfo = $ProcessInfo $Proc.Start() | Out-Null When I type $Proc at the command, $Proc I get this: Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id ProcessName ----

问题 I want to be able to present "today" and "yesterday" for recent dates in my application. I've got a date formatter in use currently to show dates (retrieved from data records) and will keep using this for anything more than a couple of days old. I just really like the way the SMS app in the iPhone shows dates for recent messages and would like to emulate this. The time-stamps that I have to work with are generated on a server that the phone downloads the data records from. All times are

问题 I have a MaskedTextBox using the mask "00/00/\2\000" to restrict input to a format of XX/XX/20XX , with the Text property bound to MyBindingSource.SomeProperty of type DateTime . Recently, values with a single-digit month or day recently started displaying incorrectly. I expect that the ToString() method is being called on the value at some point in data binding, and I believe the call is not padding month / day with zeroes. I tried setting the format type of the MaskedTextBox.Text property
