  • Using True and False to select items to print

    - by user1753915
    I have a workbook that contains rows of information that needs to printed to a seperate worksheet in excel. I am trying to utilize a checkbox to indicate which items need to print and which items need to be skipped. The checkbox is located in column "A" and once checked and the macro ran, I want it to pick up the data in each cell of that particular row, transfer it a seperate worksheet (form), prompt and save the worksheet to pdf, clear the form, and then return to the main worksheet to continue until all rows have been checked. However, right now, my code is only looping through the very first "TRUE" statement and not continuing to the rest. Here is the code: Private Sub CommandButton1_Click() On Error GoTo ErrHandler: Dim i As Integer For i = 1 To 10 If ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = False Then Else If ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = True Then Call PrintWO Else End If Do Until ActiveSheet.OLEObjects("CheckBox" & i).Object.Value = 10 MsgBox "Nothing Selected to Print" Exit Do Exit Sub Loop End If Next i ErrHandler: End Sub

  • Loop to check all 14 days in the pay period

    - by Rachel Ann Arndt
    Name: Calc_Anniversary Input: Pay_Date, Hire_Date, Termination_Date Output: "Y" if is the anniversary of the employee's Hire_Date, "N" if it is not, and "T" if he has been terminated before his anniversary. Description: Create local variables to hold the month and day of the employee's Date_of_Hire, Termination_Date, and of the processing date using the TO_CHAR function. First check to see if he was terminated before his anniversary. The anniversary could be on any day during the pay period, so there will be a loop to check all 14 days in the pay period to see if one was his anniversary. CREATE OR replace FUNCTION Calc_anniversary( incoming_anniversary_date IN VARCHAR2) RETURN BOOLEAN IS hiredate VARCHAR2(20); terminationdate VARCHAR(20); employeeid VARCHAR2(38); paydate NUMBER := 0; BEGIN SELECT Count(arndt_raw_time_sheet_data.pay_date) INTO paydate FROM arndt_raw_time_sheet_data WHERE paydate = incoming_anniversary_date; WHILE paydate <= 14 LOOP SELECT To_char(employee_id, '999'), To_char(hire_date, 'DD-MON'), To_char(termination_date, 'DD-MON') INTO employeeid, hiredate, terminationdate FROM employees, time_sheet WHERE employees.employee_id = time_sheet.employee_id AND paydate = pay_date; IF terminationdate > hiredate THEN RETURN 'T'; ELSE IF To_char(SYSDATE, 'DD-MON') = To_char(hiredate, 'DD-MON')THEN RETURN 'Y'; ELSE RETURN 'N'; END IF; END IF; paydate := paydate + 1; END LOOP; END; Tables I am using CREATE TABLE Employees ( EMPLOYEE_ID INTEGER, FIRST_NAME VARCHAR2(15), LAST_NAME VARCHAR2(25), ADDRESS_LINE_ONE VARCHAR2(35), ADDRESS_LINE_TWO VARCHAR2(35), CITY VARCHAR2(28), STATE CHAR(2), ZIP_CODE CHAR(10), COUNTY VARCHAR2(10), EMAIL VARCHAR2(16), PHONE_NUMBER VARCHAR2(12), SOCIAL_SECURITY_NUMBER VARCHAR2(11), HIRE_DATE DATE, TERMINATION_DATE DATE, DATE_OF_BIRTH DATE, SPOUSE_ID INTEGER, MARITAL_STATUS CHAR(1), ALLOWANCES INTEGER, PERSONAL_TIME_OFF FLOAT, CONSTRAINT pk_employee_id PRIMARY KEY (EMPLOYEE_ID), CONSTRAINT fk_spouse_id FOREIGN KEY (SPOUSE_ID) REFERENCES EMPLOYEES (EMPLOYEE_ID)) / CREATE TABLE Arndt_Raw_Time_Sheet_data ( EMPLOYEE_ID INTEGER, PAY_DATE DATE, HOURS_WORKED FLOAT, SALES_AMOUNT FLOAT, CONSTRAINT pk_employee_id_pay_date_time PRIMARY KEY (EMPLOYEE_ID, PAY_DATE), CONSTRAINT fk_employee_id_time FOREIGN KEY (EMPLOYEE_ID) REFERENCES EMPLOYEES (EMployee_ID)); error FUNCTION Calc_Anniversary compiled Warning: execution completed with warning

  • Simplifying loop in Objective-C

    - by Joe Habadas
    I have this enormous loop in my code (not by choice), because I can't seem to make it work any other way. If there's some way make this simple as opposed to me repeating it +20 times that would be great, thanks. for (NSUInteger i = 0; i < 20; i++) { if (a[0] == 0xFF || b[i] == a[0]) { c[0] = b[i]; if (d[0] == 0xFF) { d[0] = c[0]; } ... below repeats +18 more times with [i+2,3,4,etc] ... if (a[1] == 0xFF || b[i + 1] == a[1]) { c[1] = b[i + 1]; if (d[1] == 0xFF) { d[1] = c[1]; } ... when it reaches the last one it calls a method ... [self doSomething]; continue; i += 19; ... then } repeats +19 times (to close things)... } } } I've tried almost every possible combo of things that I know of attempting to make this smaller and efficient. Take a look at my flow chart — pretty huh? i'm not a madman, honest.

  • Program is not displaying output correctly

    - by Dave Lee
    My program is suppose to display information from a text file. The text file is here http://pastebin.com/qB6nX2x4 I cant find the problem in my program. I think it has to deal with the looping but im not sure. My program runs correctly but only displays the first line of text. Any help would be appreciated. #include <iostream> #include <string> #include <cstdlib> #include <fstream> using namespace std; int buildArrays(int A[],int B[],int C[]) { int i=0,num; ifstream inFile; inFile.open("candycrush.txt"); if(inFile.fail()) { cout<<"The candycrush.txt input file did not open"<<endl; exit(-1); } while(inFile) { inFile>>num; A[i]=num; inFile>>num; B[i]=num; inFile>>num; C[i]=num; i++; } inFile.close(); return i; } void printArrays( string reportTitle, int levelsArray[], int scoresArray[], int starsArray[], int numberOfLevels ) { cout<<endl; cout<<reportTitle<<endl; cout<<"Levels\tScores\tStars"<<endl; cout<<"---------------------"<<endl; for(int i=0;i<numberOfLevels;i++) { cout<<levelsArray[i]<<"\t"<<scoresArray[i]<<"\t"; for(int j=0;j<starsArray[j];j++) { cout<<"*"; } cout<<endl; } } void sortArrays( int levelsArray[], int scoresArray[], int starsArray[], int numberOfLevels ) { for(int i=0;i<numberOfLevels;i++) { for(int j=0;j<numberOfLevels;j++) { if(levelsArray[i]<levelsArray[j]) { int temp1=levelsArray[i]; int temp2=scoresArray[i]; int temp3=starsArray[i]; levelsArray[i]=levelsArray[j]; scoresArray[i]=scoresArray[j]; starsArray[i]=starsArray[j]; levelsArray[j]=temp1; scoresArray[j]=temp2; starsArray[j]=temp3; } } } } int main() { const int MAX=400; int levelsArray[MAX]; int scoresArray[MAX]; int starsArray[MAX]; int numberOfLevels=buildArrays(levelsArray,scoresArray,starsArray); printArrays( "Candy Crush UNSORTED Report", levelsArray, scoresArray, starsArray, numberOfLevels ); sortArrays( levelsArray, scoresArray, starsArray, numberOfLevels); printArrays( "Candy Crush SORTED Report", levelsArray, scoresArray, starsArray, numberOfLevels ); system("pause"); }

  • i integer does not +1 the 1st time

    - by Hwang
    I have a gallery where it will load an image after a previous image is loaded, so every time 'i' will +1 so that it could move to the next image. This code works fine on my other files, but I dunno why it doesn't work for the current file. Normally if I trace 'i' the correct will be 0,1,2,3,4,5,6... etc adding on till the limit, but this files its 'i' repeat the 1st number twice, only it continues to add 0,0,1,2,3,4,5,6...etc The code is completely the same with the other file I'm using, but I don't know why it just doesn't work here. The code does not seems to have any problem. Anyway i can work around this situation? private var i:uint=0; private function loadItem():void { if (i<myXMLList.length()) { loadedPic=myXMLList[i].thumbnails; galleryLoader = new Loader(); galleryLoader.load(new URLRequest(loadedPic)); galleryLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,picLoaded); } else { adjustImage(); } } private function picLoaded(event:Event):void { var bmp=new Bitmap(event.target.content.bitmapData); bmp.smoothing=true; bmpArray.push(bmp); imagesArray[i].addChild(bmp); i++; loadItem(); }

  • PHP loop hanging/interspersed/threaded through HTML

    - by sandyv
    I can't figure out how to say what I'm talking about which is a big part of why I'm stuck. In PHP I often see code like this html <?php language construct that uses brackets { some code; ?> more html <?php some more code; } ?> rest of html Is there any name for this? Having seen this lead me to try it out so here is a concrete example whose behavior doesn't make sense to me <div id="content"> <ul id="nav"> <?php $path = 'content'; $dir = dir($path); while(false !== ($file = $dir->read())) { if(preg_match('/.+\.txt/i', $file)) { echo "<li>$file</li>"; ?> </ul> <?php echo file_get_contents($path . '/' . $file); } } ?> </div> Which outputs roughly <div><ul><li></li></ul><li></li>...</div> instead of <div><ul><li></li>...</ul></div> which is what I thought would happen and what I want to happen.

  • Write the longest possible loop.

    - by Abhay
    Hello Group, Recently I was asked this question in a technical discussion. What is the longest possible loop that can be written in a programming language? This loop has to be as long as possible and yet not an infinite loop and should not end-up crashing the program (Recursion etc...) I honestly did not know how to attack this problem, so I asked him if is it practically possible. He said using some computer science concepts, you can arrive at a hypothetical number which may not be practical but nevertheless it will still not be infinite. Anyone here; knows how to analyse / attack this problem. P.S. Choosing some highest limit for a type that can store the highest numerical value is apparently not an answer. Thanks in advance,

  • How to store multiple variables from a File Input of unknown size in Java?

    - by AlphaOmegaStrife
    I'm a total beginner with my first programming assignment in Java. For our programming assignment, we will be given a .txt file of students like so: 3 345 Lisa Miller 890238 Y 2 <-(Number of classes) Mathematics MTH345 4 A Physics PHY357 3 B Bill Wilton 798324 N 2 English ENG378 3 B Philosophy PHL534 3 A Dandy Goat 746333 Y 1 History HIS101 3 A" The teacher will give us a .txt file on the day of turning it in with a list of unknown students. My problem is: I have a specific class for turning the data from the file into variables to be used for a different class in printing it to the screen. However, I do not know of a good way to get the variables from the input file for the course numbers, since that number is not predetermined. The only way I can think of to iterate over that unknown amount is using a loop, but that would just overwrite my variables every time. Also, the teacher has requested that we not use any JCL classes (I don't really know what this means.) Sorry if I have done a poor job of explaining this, but I can't think of a better way to conceptualize it. Let me know if I can clarify. Edit: public static void analyzeData() { Scanner inputStream = null; try { inputStream = new Scanner(new FileInputStream("Programming Assignment 1 Data.txt")); } catch (FileNotFoundException e) { System.out.println("File Programming Assignment 1 Data.txt could not be found or opened."); System.exit(0); } int numberOfStudents = inputStream.nextInt(); int tuitionPerHour = inputStream.nextInt(); String firstName = inputStream.next(); String lastname = inputStream.next(); String isTuitionPaid = inputStream.next(); int numberOfCourses = inputStream.nextInt(); String courseName = inputStream.next(); String courseNumber = inputStream.next(); int creditHours = inputStream.nextInt(); String grade = inputStream.next(); To show the methods I am using now, I am just using a Scanner to read from the file and for Scanner inputStream, I am using nextInt() or next() to get variables from the file. Obviously this will not work when I do not know exactly how many classes each student will have.

  • How do I make a new div with a specific Id + n?

    - by Noor
    I've got a button and when it's pushed this code launches: var nrDivs = "1" var neuDiv = document.createElement("div"); neuDiv.setAttribute("Id","theDiv" + nrDivs); neuDiv.innerHTML = "Text"; $('#allDivs').append(neuDiv); newfeed.draw(neuDiv); I know that right now the script creates a new div with the ID: theDiv1. What I'm trying to do is when I click the button a second time, it creates a div with the ID: theDiv2. Each time the user presses the button there should be a new div drawn and I'm trying to target that new div and insert dynamic text. Thanks, Noor

  • How to make cycle over cycles in Java?

    - by Roman
    I would like to make a cycle over the following elements: [1,2,11,12,21,22,111,112,121,122,....,222222] or for example [1,2,3,11,12,13,21,22,23,31,32,33,111,112,113,... 333333333] How can I make it in Java? In my particular case I use 4 digits (1,2,3,4) and the length of the last number can be from 1 to 10. I managed to do it in Python and PHP. In the first case I used list over lists. I started from [[1],[2],] then for every element of the list I added 1 and 2, so I got [[1,1],[1,2],[2,1],[2,2]] and so on: nchips = sum(chips) traj = [[]] last = [[]] while len(last[0]) < nchips: newlast = [] for tr in last: for d in [1,2,3,4]: newlast.append(tr + [d]) last = newlast traj += last When I did it in PHP I used number with base 3. But it was a tricky and non elegant solution. for ($i=-1; $i<=$n; $i+=1) { if ($i>-1) { $n5 = base_convert($i,10,5); $n5_str = strval($n5); $tr = array(); $found = 0; for ($j=0; $j<strlen($n5_str); $j+=1) { $k = $n5_str[$j]; if ($k==0) { $found = 1; break; } array_push($tr,$k); } if ($found==1) continue; } else { $tr = array(); } } Can it be done easily in Java?

  • a nicer way to create structs in a loop

    - by sandra
    Hi guys, I haven't coded in C++ in ages. And recently, I'm trying to work on something involving structs. Like this typedef struct{ int x; int y; } Point; Then in a loop, I'm trying to create new structs and put pointers to them them in a list. Point* p; int i, j; while (condition){ // compute values for i and j with some function... p = new Point; p* = {i, j}; //initialize my struct. list.append(p); //append this pointer to my list. } Now, my question is it possible to simplify this? I mean, the pointer variable *p outside of the loop and calling p = new Point inside the loop. Isn't there a better/nicer syntax for this?

  • PHP: Loop through text file and isolate lines which a specific "starting point"

    - by Mestika
    Hi everyone, I’m trying to reduce some editing time within some textfiles where there approximately are 10.000 lines of text, but I only need around 200 or some. The text file relies on a almost specific pattern but it deviates from time to time but my “focus” in order to select the right line to keep is, that the line always starts with: z3455 and then have a variable afterwards, e.g.: z3455 http://url.com/data1/data1.1/data1.3/ (342kb) I have an algorithm to capture the URL and its content but now I need some way to loop through the text file, deleting all lines except does that starts with z3455 and then “push” them together so they are listed underneath each other. I’ve tried different approaches for this in PHP but can’t seem to find a correct function. I can “isolate” a specific line number but when it deviates I can’t use this approach fully. I hope that someone can help me, either by providing the code or knocking me in the right direction to how I’ll solve this problem. Thanks in advance Sincerely - Mestika

  • How can I optimize this loop?

    - by Moshe
    I've got a piece of code that returns a super-long string that represents "search results". Each result is represented by a double HTML break symbol. For example: Result1<br><br>Result 2<br><br>Result3 I've got the following loop that takes each result and puts it into an array, stripping out the break indicator, "kBreakIndicator" (<br><br>). The problem is that this lopp takes way too long to execute. With a few results it's fine, but once you hit a hundred results, it's about 20-30 seconds slower. It's unacceptable performance. What can I do to improve performance? Here's my code: content is the original NSString. NSMutableArray *results = [[NSMutableArray alloc] init]; //Loop through the string of results and take each result and put it into an array while(![content isEqualToString:@""]){ NSRange rangeOfResult = [content rangeOfString:kBreakIndicator]; NSString *temp = (rangeOfResult.location != NSNotFound) ? [content substringToIndex:rangeOfResult.location] : nil; if (temp) { [results addObject:temp]; content = [[[content stringByReplacingOccurrencesOfString:[NSString stringWithFormat:@"%@%@", temp, kBreakIndicator] withString:@""] mutableCopy] autorelease]; }else{ [results addObject:[content description]]; content = [[@"" mutableCopy] autorelease]; } } //Do something with the results array. [results release];

  • Looping through covariates in regression using R

    - by Kyle Peyton
    I'm trying to run 96 regressions and save the results as 96 different objects. To complicate things, I want the subscript on one of the covariates in the model to also change 96 times. I've almost solved the problem but I've unfortunately hit a wall. The code so far is, for(i in 1:96){ assign(paste("z.out", i,sep=""), lm(rMonExp_EGM~ TE_i+ Month2+Month3+Month4+Month5+Month6+Month7+Month8+Month9+ Month10+Month11+Month12+Yrs_minus_2004 + as.factor(LGA),data=Pokies)) } This works on the object creation side (e.g. I have z.out1 - z.out96) but I can't seem to get the subscript on the covariate to change as well. I have 96 variables called TE_1, TE_2 ... TE_96 in the dataset. As such, the subscript on TE_, the "i" needs to change to correspond to each of the objects I create. That is, z.out1 should hold the results from this model: z.out1 <- lm(rMonExp_EGM~ TE_1 + Month2+Month3+Month4+Month5+Month6+Month7+Month8+Month9+ Month10+Month11+Month12+Yrs_minus_2004 + as.factor(LGA),data=Pokies) And z.out96 should be: z.out96 <- lm(rMonExp_EGM~ TE_96+ Month2+Month3+Month4+Month5+Month6+Month7+Month8+Month9+ Month10+Month11+Month12+Yrs_minus_2004 + as.factor(LGA),data=Pokies) Hopefully this makes sense. I'm grateful for any tips/advice. cheers, kyle

  • Should try...catch go inside or outside a loop?

    - by mmyers
    I have a loop that looks something like this: for(int i = 0; i < max; i++) { String myString = ...; float myNum = Float.parseFloat(myString); myFloats[i] = myNum; } This is the main content of a method whose sole purpose is to return the array of floats. I want this method to return null if there is an error, so I put the loop inside a try...catch block, like this: try { for(int i = 0; i < max; i++) { String myString = ...; float myNum = Float.parseFloat(myString); myFloats[i] = myNum; } } catch (NumberFormatException ex) { return null; } But then I also thought of putting the try...catch block inside the loop, like this: for(int i = 0; i < max; i++) { String myString = ...; try { float myNum = Float.parseFloat(myString); } catch (NumberFormatException ex) { return null; } myFloats[i] = myNum; } So my question is: is there any reason, performance or otherwise, to prefer one over the other? EDIT: The consensus seems to be that it is cleaner to put the loop inside the try/catch, possibly inside its own method. However, there is still debate on which is faster. Can someone test this and come back with a unified answer? (EDIT: did it myself, but voted up Jeffrey and Ray's answers)

  • Basic Python While loop compound conditional evaluation

    - by dbjohn
    In Python IDLE Shell it seems I cannot use a compound conditional expression and a while loop. I tried it within brackets too. k=0 m=0 while k<10 & m<10: print k k +=1 m+=1 If I write while k<10: print k k+=1 This does work. Is there a way I could achieve the first block of code with the "and" operator. I have done it in Java. Do I just need to put together "if" statements to achieve the same functionality in Python?

  • SASS color array

    - by Eric Holmes
    I am trying to write a loop that will cycle through colors and condense the amount of code in my scss file. Here is a simple example of what I have: $color1: blue; $color2: red; $color3: white; $color4: black; .color1-bg { background-color: $color1; } .color2-bg { background-color: $color2; } .color1-border { border-color: $color1; } .color2-border { border-color: $color2; } And so on. I am looking for a way to make the equivalent of a foreach loop, and cycle through an 'array' of colours by index. Something like this: @each $color in $color1, $color2, $color3, $color4 { .{$color}-bg { background-color: $color; .{$color}-border { border-color: $color; } I know the syntax is wrong, but that is my thinking process. Thanks for the help!

  • Help me refactor my World Cup Challenge Script

    I am setting up a World Cup Challenge between some friends, and decided to practice my Ruby and write a small script to automate the process. The Problem: 32 World Cup qualifiers split into 4 tiers by their Fifa ranking 8 entries Each entry is assigned 1 random team per tier Winner takes all :-) I wrote something that suffices yet is admittedly brute force. But, in my attempt to improve my Ruby, I acknowlege that this code isn't the most elegant solution around - So I turn to you, the experts, to show me the way. It may be more clear to check out this gist - https://gist.github.com/91e1f1c392bed8074531 My Current (poor) solution: require 'yaml' @teams = YAML::load(File.open('teams.yaml')) @players = %w[Player1 Player2 Player3 Player4 Player5 Player6 Player7 Player8] results = Hash.new players = @players.sort_by{rand} players.each_with_index do |p, i| results[p] = Array[@teams['teir_one'][i]] end second = @players.sort_by{rand} second.each_with_index do |p, i| results[p] << @teams['teir_two'][i] end third = @players.sort_by{rand} third.each_with_index do |p, i| results[p] << @teams['teir_three'][i] end fourth = @players.sort_by{rand} fourth.each_with_index do |p, i| results[p] << @teams['teir_four'][i] end p results I am sure there is a better way to iterate through the tiers, and duplicating the @players object ( dup() or clone() maybe?) So from one Cup Fan to another, help me out.
