问题 I am working with large data. I have 2 datasets as ORIGIN and DESTINATION. Using google API, I would like to compute the direction from ORIGIN dataset to DESTINATION dataset. The data is as follows: Origin(masterdata): No xcoord ycoord 1 109.6663 -6.897970 2 109.6584 -6.897511 3 109.6519 -6.893822 4 109.6586 -6.896936 5 109.6651 -6.897484 Destination(xystation3375) No Long Lat 1 109.6644 -6.889696 2 109.7008 -6.902980 key = "Google API dataset_origin <- as.data.frame(masterdata[1:500,])

问题 I'm trying to add a custom query to a WordPress template and include pagination but my pagination isn't appearing, for example's sake I'm trying to add this to page.php. I have the following markup which works perfectly when place inside a category template like category.php, the pagination shows up and functions just fine. The issue is that the pagination doesn't appear when the same code is place in page.php or any custom page template. The query: <?php $paged = (get_query_var('paged')) ?

问题 Excerpt from Chapter 3.5 of the Rust Book: ... we use the break keyword with the value counter * 2 . After the loop, we use a semicolon to end the statement that assigns the value to result . Plus the code snippet: fn main() { let mut counter = 0; let result = loop { counter += 1; if counter == 10 { break counter * 2; } }; println!("The result is {}", result); } I understand how this works and why the result is 20, but I noticed that if I remove the semicolon on the line that contains the

问题 I am trying to: Use a value from Table A (column - person's name) to filter on Table B in separate sheet Copy filtered Table B into the body of an email (outlook) Send outlook email to email address for that recipient (from Table A) Loop through the process again for the next person in Table A Example of Table A: Example of Table B: So for example for the first iteration Take Dave Jones from Table A and filter Table B for Dave Jones. Copy the filtered Table B to the body of a new email Send

问题 Suppose I have got a shorthand if-else statement inside a loop as in this case : for(...) { a = b == c ? b : c; // More unnecessary code if the result was true. } And I would like to break the loop by the result of the condition: for(...) { a = b == c ? b break : c; // Now the unnecessary code is not executed. } I realize I could just type it in a full way as in this example: for(...) { if( b == c ) { a = b; break; } else { a = c; } // Now the unnecessary code is not executed. } But it is too

问题 This question already has answers here : Listen for key press in .NET console app (9 answers) Closed 3 years ago . Currently I am using this code: using System; namespace Project { class MainClass { public static void Main (string[] args) { bool key = false; while (key == false) { Console.WriteLine ("Loop"); } } } } Which works fine, but I wanted to make the loop stop when a key is pressed. I tried this: using System; namespace Project { class MainClass { public static void Main (string[]
