Conditional formatting for HTML Signatures in Outlook 2016+

由 牧云@^-^@ 提交于 2019-12-13 20:12:30
问题 So, I'm trying to understand the conditional formatting in HTML email signatures within Outlook 2016 and above. I have this short demo code: <!DOCTYPE HTML> <html> <head> </head> <body> <!--[if mso]> <p style="background: blue"> <![endif]--> <p style="background: pink">TEST TEST TEST</p> <!--[if mso]> </p> <![endif]--> </body> </html> Which, by my logic, should change the background colour to blue, if the HTML is rendered within Outlook 2016. However, it's pink. Is my code incorrect logically

Split CSV to Multiple Files Containing a Set Number of Unique Field Values

由 蓝咒 提交于 2019-12-13 16:30:26
问题 As a beginner of awk I am able to split the data with unique value by awk -F, '{print >> $1".csv";close($1)}' myfile.csv But I would like to split a large CSV file based on additional condition which is the occurrences of unique values in a specific column. Specifically, with input 111,1,0,1 111,1,1,1 222,1,1,1 333,1,0,0 333,1,1,1 444,1,1,1 444,0,0,0 555,1,1,1 666,1,0,0 I would like the output files to be 111,1,0,1 111,1,1,1 222,1,1,1 333,1,0,0 333,1,1,1 and 444,1,1,1 444,1,0,1 555,1,1,1 666

Warning: Assignment in condition

由 非 Y 不嫁゛ 提交于 2019-12-13 13:24:31
问题 One thing that has always bugged me is that when checking my php scripts for problems I get the warning "bool-assign : Assignment in condition" and I get them a lot. e.g.: $guests = array(); $sql = "SELECT * FROM `guestlist`"; $result = mysql_query($sql); while($row = mysql_fetch_assoc($result)) $guests[] = $row['name']; Is there a different way to get multiple or all rows into an object or array? Or is there nothing wrong with this method? 回答1: try doing this instead: $guests = array(); $sql

Applying Conditions on Pandas DataFrame Columns before reading csv or tsv files

由 こ雲淡風輕ζ 提交于 2019-12-13 12:22:30
问题 Is it possible to set conditions (filters) for the DataFrame columns before reading a csv or tsv files, If I am already aware of the column names and types? If yes, how? For Example: Consider there are two numerical columns (col1 and col2) in a very big file. I do not want to load whole file in the memory and select only those rows where col1 greater than col2. Therefore, first, I want to set the condition on the dataframe that it should read only those rows from the csv file where col1 is

R all combinations of 3 vectors with conditions

由 假如想象 提交于 2019-12-13 07:34:37
问题 I have two vectors vector1 = c(0.9,0.8,0.7,0.6,0.5) vector2 = c(10,20,30) I now want all combinations of the elements in these vectors, while vector2 is used twice. I use expand.grid() to this. combinations = expand.grid(vector1,vector2,vector2) The result is a frame with the columns Var1 , Var2 and Var3 . Now I want to combine the first vector with the second vector with some conditions. E.g. 0.9 to 0.7 from vector1 should only be combined with Var2 >= Var3 . And 0.6 to 0.5 should only be

Disable submit button if all three of three specific dropdown fields are empty

由 一世执手 提交于 2019-12-13 07:08:15
问题 There are four dropdowns in the form. One is optional. Of the other three, at least one has to be chosen. I have a script that I'm using on a form with one field, that disables submit until a selection is made. But I can't figure out and can't find how to adapt it to be disabled until at least one of three specific dropdowns has a selection made. Here's the current script: jQuery(function($) { $('#ssbbcmodal-attribute').change(function() { var empty = false; $('#ssbbcmodal-attribute').each

Conditional logic in Rails/ActionMailer for two versions of same article to readers/subscribers

由 戏子无情 提交于 2019-12-13 07:00:11
问题 Users are either readers or subscribers. When a new article is published, subscribers get a full text e-mail, readers get a teaser text. Assuming scopes in the model for readers/subscribers, is this right or do I need another conditional for each type of user? if @article.valid? User.subscribers.each do |user| ArticleMailer.send_article_full(@article, user).deliver_now end User.readers.each do |user| ArticleMailer.send_article_teaser(@article, user).deliver_now end redirect_to :root, notice:

Routing an object in C# without using switch statements

由 折月煮酒 提交于 2019-12-13 06:48:28
问题 I am writing a piece of software in c# .net 4.0 and am running into a wall in making sure that the code-base is extensible, re-usable and flexible in a particular area. We have data coming into it that needs to be broken down in discrete organizational units. These units will need to be changed, sorted, deleted, and added to as the company grows. No matter how we slice the data structure we keep running into a boat-load of conditional statements (upwards of 100 or so to start) that we are
