问题 I have 60 different character arrays loaded in my workspace (Book01, Book02, ..., Book60). For example, Book01 is a 1x202040 char. I'm working in a script file, and trying to separate the last sentence("RandomInfoAtEnd") of Book45 until Book58: WholeBook = Book50; % Call Array for test for i = 1:60 book = eval(['Book' num2str(i)]); if i >= 45 && i <= 58 % Procedure to separate last sentence. Chr = convertStringsToChars(WholeBook); SearchedUnit = '.!?' ; % Sentence end punctuation idx =

问题 I have created a dictionary to combine several bits of data for one event. For example, NameA can have four entries depending on the value in column 5. It can be A, B, C, D. However i would like to display all this information from A, B, C, D on one row in a table for NameA as the end product. So i have created a dictionary with a class module to show this, with the class listing all possible variables to display in final output. Depending on the entries (A, B, C, D) the value in column 1 can

问题 I am trying to delete a row if cells in column V is not equal to F or V. This code deletes everything. For i = RowCount To 1 Step -1 If Range("V" & i).Value <> "F" Or Range("V" & i).Value <> "V" Then Rows(i).Delete Next i 回答1: Your logic seems incorrect. By changing the or to an and , you will then be evaluating the proper boolean arithmetic. Right now, you are checking not "v" and not "f" which is always false. No matter the input, this will always have answer be true. 回答2: Answer to Else

问题 Hello Stack Overlords! I'm currently trying to put together a little coding project. Something simple, but I'm having a rather difficult time. The objective, clear out three cells once the time of day, based on one of those cells, passes. Essentially - G9 contains the the time I want the cells to be cleared. Once it has gone past the time of day specified in G9, I'd like cells D6, D9 and G9 cleared. I've set up a way of doing this using an IF statement, both from the sheets side, and scripts

问题 Update Sorry for the delay in responding. I was traveling yesterday when I sent that in. I am on version 5.6. This is what I was thinking of and it does mark when there is change, but the issue is the sort causes the result set to fall out of order. I guess I will need to create a temporary table and just apply the conditional formatting once the order has been set. SET @previousstate = ''; SELECT frm.fi_details.PortfolioCode AS 'Portfolio Code', id, if(@previousstate != frm.fi_details

问题 Very simple problem that I can't seem to wrap my head around. I'm writing a bicycle program that calculates MPH based on the cadence and gears set on the bike. The gears that can be set are between 1-3 and the cadence is between 1-100. TL;DR If a user enters a number outside of that range, I'm having trouble figuring out how to have the program prompt them again until they enter the correct range. I'm also having trouble figuring out how to get the entire BicycleTest program to loop over once

问题 Couldn't find any other answer on the site that covers this. If else is run and an error message is displayed, is it possible to restart the program by looping back to the start instead of restarting the console? class Program { static void Main(string[] args) { int User; int Array; StreamWriter outfile = new StreamWriter("C://log.txt"); Console.WriteLine("Input an number between 1 and 100"); User = Convert.ToInt32(Console.ReadLine()); if (User < 101 && User > 0) { for (Array = 1; Array <=
