Cell is empty but IsEmpty is not working

由 廉价感情. 提交于 2019-12-10 16:40:51
问题 I am writing an IF statement that uses the IsEmpty function to determine if True or False. I tried it both on a cell with a value (e.g., PRB2039) and on a blank cell to test my code, and the result is the same. I removed formatting, and tried it on a new worksheet. I don't know what I'm doing wrong. 回答1: I prefer using If Len(Trim(Cells(i, 1).Value))=0 Then Msgbox "Empty" 回答2: As suggested by @PatricK you may consider using ISBLANK function instead of IsEmpty function. ISBLANK function

ASP Session variables: Is “” same as IsEmpty?

问题 In ASP an uninitialized Session variable Is Empty. I know that the correct way to check for a Session value, and remove a value, is the following: IF NOT IsEmpty(Session("myVar")) THEN ' Go ahead and use Session("myVar") ... ' Now if we're all done with myVar then remove it: Session.Contents.Remove("myVar") END IF I've inherited a codebase where Application and Session variables are typically set = "" after use, and all tests for a value are of the form (Sessions("myVar") = "") . This test

What is the best way to check if a tuple has any empty/None values in Python?

由 南楼画角 提交于 2019-12-09 14:06:09
问题 What is the best/most efficient way to check if all tuple values? Do I need to iterate over all tuple items and check or is there some even better way? For example: t1 = (1, 2, 'abc') t2 = ('', 2, 3) t3 = (0.0, 3, 5) t4 = (4, 3, None) Checking these tuples, every tuple except t1 , should return True, meaning there is so called empty value. P.S. there is this question: Test if tuple contains only None values with Python, but is it only about None values 回答1: It's very easy: not all(t1) returns

Skipping empty files in Gnuplot

问题 I am using gnuplot 4.6 . Also, I know that a similar question was asked more than a year ago here. The answer to that requires to write a small bash script. I want to know if it is possible to achieve this from within gnuplot script, especially when gnuplot-4.6 has so many cool features added. I am trying to achieve something like this : set xrange[xL:xU] set yrange[yL:yU] plot "file1.dat" using 1:2 w l lt 1 lw 1 lc 3,\ "file2.dat" using 1:2 w l lt 1 lw 1 lc 3 I am repeating the above process

AngularJS - controller doesn't get data from service when using $http

由 独自空忆成欢 提交于 2019-12-05 03:22:02
问题 I have simple web app where I like to load some data from json. At the moment the data is hardcoded within my service and everything is working. When I change my service to load the same data from an external json file the controller renders the view before it gets some data. That's what it looks like now: function() { var tripsService = function() { var trips = [{ .... SOME DATA }]; this.getTrips = function() { return trips; }; }; angular.module('customersApp').service('tripsService',

Need to Show a message when DataList is Empty

问题 I'm using DataList to show records on Client Site of my web page. I need to show a message when my DataList is empty. Is there a property of Datalist? How to show that message? 回答1: EmptyDataText property is not supported by DataList yet. But you can achieve almost same functionality using the following trick: <FooterTemplate> <asp:Label Visible='<%#bool.Parse((DataList1.Items.Count==0).ToString())%>' runat="server" ID="lblNoRecord" Text="No Record Found!"></asp:Label> </FooterTemplate> That
