Can any1 explain how we can create Excel WITHOUT using INTEROP in c# window service.
So that I can apply styles also to the generating excel as I wish.
Rigin
You can use one of the Excel libraries. I use this C# Excel library.
See also this sample of code:
http://www.easyxls.com/manual/FAQ/export-to-excel-in-dot-net.html
You can create both XLS or XLSX documents.
You can create excel in windows services like below:
public static void GenerateExcel(DataTable DT, string fullFileName, string rptHeader, string SheetName)
{
try
{
var file = new FileInfo(fullFileName);
string currentFileName = System.IO.Path.GetFileName(fullFileName);
ExcelPackage excel = new ExcelPackage(file);
var sheetcreate = excel.Workbook.Worksheets.Add("Sheet1");
//rptHeader = getCaption(rptHeader);
char c = 'A';
c = (char)(((int)c) + DT.Columns.Count - 1);
//sheetcreate.Cells["A1:" + c+"1"].Value = rptHeader;
sheetcreate.Cells["A1:D1"].Value = rptHeader;
sheetcreate.Cells["A1:" + c + "1"].Style.Fill.PatternType = ExcelFillStyle.Solid;
//sheetcreate.Cells["A1:" + c + "1"].Style.Fill.BackgroundColor.SetColor(System.Drawing.ColorTranslator.FromHtml("#c6c6c6"));
sheetcreate.Cells[1, 1, 1, DT.Columns.Count].Merge = true;
sheetcreate.Cells[1, 1, 1, DT.Columns.Count].Style.Font.Bold = true;
int col = 0;
foreach (DataColumn column in DT.Columns)
{
sheetcreate.Cells[2, ++col].Value = column.ColumnName;
sheetcreate.Cells[2, col].Style.Font.Bold = true;
sheetcreate.Cells[2, col].Style.Border.BorderAround(OfficeOpenXml.Style.ExcelBorderStyle.Thin);
sheetcreate.Cells[2, col].Style.HorizontalAlignment = ExcelHorizontalAlignment.Center;
}
if (DT.Rows.Count > 0)
{
int row = 2;
for (int eachRow = 0; eachRow < DT.Rows.Count; ) //looping each row
{
bool havingText = false;
for (int eachColumn = 1; eachColumn <= col; eachColumn++) //looping each column in a row
{
var eachRowObject = sheetcreate.Cells[row + 1, eachColumn];
eachRowObject.Style.Fill.PatternType = ExcelFillStyle.Solid;
eachRowObject.Value = DT.Rows[eachRow][(eachColumn - 1)].ToString();
if (!havingText) //checking if 'totoa' in string and setting up 'havingText' variable to color it differently
havingText = DT.Rows[eachRow][(eachColumn - 1)].ToString().ToLower().Contains("total");
//Making all cell value to left align
eachRowObject.Style.HorizontalAlignment = ExcelHorizontalAlignment.Left;
//if (CL.isDecimal(DT.Rows[eachRow][(eachColumn - 1)].ToString())) //if it is number with decimal value make it right align
//{
// eachRowObject.Style.HorizontalAlignment = ExcelHorizontalAlignment.Right;
//}
//eachRowObject.Style.Border.BorderAround(OfficeOpenXml.Style.ExcelBorderStyle.Thin); // adding border to each cells
//if (eachRow % 2 == 0) //alternatively adding color to each cell.
// eachRowObject.Style.Fill.BackgroundColor.SetColor(System.Drawing.ColorTranslator.FromHtml("#e0e0e0"));
//else
// eachRowObject.Style.Fill.BackgroundColor.SetColor(System.Drawing.ColorTranslator.FromHtml("#ffffff"));
}
if (havingText) //if any cell data containt 'total' color complete.
{
for (int eachColumn = 1; eachColumn <= col; eachColumn++)
{
sheetcreate.Cells[row + 1, eachColumn].Style.Fill.PatternType = ExcelFillStyle.Solid;
//sheetcreate.Cells[row + 1, eachColumn].Style.Fill.BackgroundColor.SetColor(System.Drawing.ColorTranslator.FromHtml("#86a9ef"));
}
}
eachRow++;
row++;
}
getLog("batch controller: in loop");
}
getLog("batch controller: 485");
sheetcreate.Cells.AutoFitColumns();
excel.Save();
}
catch (Exception e)
{
getLog("Error while generating excel=>"+e);
}
}

I'm new to Dart. I was trying to convert integer to roman. But It returns nothing. Can you guys help me? here is my code sample.
this code is from the Leetcode problem section.
class Solution {
String intToRoman(int num) {
List<int> numbers = [1,4,5,9,10,40,50,90,100,400,500,900,1000];
List<String> romans = ["I","IV","V","IX","X","XL","L","XC","C","CD","D","CM", "M"];
int index = romans.length - 1;
String roman = '';
for(num >0;numbers[index]<=num;){
roman += romans[index];
num -= numbers[index];
index -= 1;
}
return roman;
}
}
just change a little bit on the logic
.try on dartpad: https://dartpad.dev/?id
void main() {
print (intToRoman(30)); // result: XXX
}
String intToRoman(int num) {
List<int> numbers = [1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1];
List<String> romans = ["M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"];
String roman = '';
for (int i = 0; i < numbers.length; i++) {
while (num >= numbers[i]) {
roman += romans[i];
num -= numbers[i];
}
}
return roman;
}
This solution is based on Wiki:
class Solution {
/// digit: 3=Thousands(10³), 2=Hundreds(10²), 1=Tens(10), 0=Units(1)
/// Range for roman numerals: 1...3999
static final romanNumerals = <int,Map<int,String>>{
1 : {3:'M', 2:'C', 1:'X', 0:'I'},
2 : {3:'MM', 2:'CC', 1:'XX', 0:'II'},
3 : {3:'MMM', 2:'CCC', 1:'XXX', 0:'III'},
4 : {2:'CD', 1:'XL', 0:'IV'},
5 : {2:'D', 1:'L', 0:'V'},
6 : {2:'DC', 1:'LX', 0:'VI'},
7 : {2:'DCC', 1:'LXX', 0:'VII'},
8 : {2:'DCCC', 1:'LXXX', 0:'VIII'},
9 : {2:'CM', 1:'XC', 0:'IX'},
};

var list = number.toString().split('').map(int.parse).toList();
var buffer = StringBuffer();
final len = list.length;
for (var i = 0; i < len; i++) {
var digit = list[i];
if (digit == 0) continue;
buffer.write(romanNumerals[digit]![len - 1 - i]);
}
return buffer.toString();
}
/* ---------------------------------------------------------------------------- */
void intToRoman2(int number) {
print(intToRoman(number));
}
}
void main(List<String> args) {
Solution()

I use this extension to convert english numbers to persian numbers
extension StringExtensions on String {
String persianNumber() {
String number = this;
number = number.replaceAll("1", "۱");
number = number.replaceAll("2", "۲");
number = number.replaceAll("3", "۳");

number = number.replaceAll("5", "۵");
number = number.replaceAll("6", "۶");

number = number.replaceAll("9", "۹");
number = number.replaceAll("0", "۰");
return number;
}

I want to accomplish something like this:
I have a sort of "Relational" Spreadsheet, and I want rows to be colored according.
I manually choosing a unique color for each Category on the "Categories" Sheet or generating a unique color based on the string content, either would work for my use case.
Not the best solution but it works
function onEdit(e) {
if(e){
var ss = e.source.getActiveSheet();
var range = e.source.getActiveRange();
var r1 = range.getRow();
var c1 = range.getColumn();
var rowsCount = range.getNumRows();
for(var i=0; i<rowsCount; i++){
var row = ss.getRange(r1+i,1,1,ss.getMaxColumns());
updateRow(row, ss);
}
}
}
function updateRow(row, ss){
if (ss.getName() == "Entries") { // This is the sheet name
var cell = row.getCell(1,1);
var firstCellValue = cell.getValue();
if(firstCellValue){
cell.setBackgroundColor(stringToColor(firstCellValue));
}
else{
cell.setBackgroundColor(null);
}
}
}
function stringToColor(str) {
var hash = 0;
for (var i = 0; i < str.length; i++) {
hash = str.charCodeAt(i) + ((hash << 5) - hash);
}
var colour = '#';
for (var i = 0; i < 3; i++) {
var value = (hash >> (i * 8)) & 0xFF;
colour += ('00' + value.toString(16)).substr(-2);
}
return colour;
}
Based on this answer
in conditional formatting select the range you want to apply colors, select color, choose Text is exactly and set value:
Setting colors of cells 1 by 1 is extremely slow. It is advised to do that by assigning an array to the range. I read about that and there is often refered to the following sample. However I can't get this to work so it doesn't help me.
var cell = sheet.getRange('a1');
var colors = new Array(100);
for (var y = 0; y < 100; y++) {
xcoord = xmin;
colors[y] = new Array(100);
for (var x = 0; x < 100; x++) {
colors[y][x] = getColorFromCoordinates(xcoord, ycoord);
xcoord += xincrement;
}
ycoord -= yincrement;
}
sheet.getRange(1, 1, 100, 100).setBackgroundColors(colors);
My piece of code is the following and ends with the message (error): Cannot convert array to object[[]], pointing at the last line.
function TabelMarkeren() {
var selection = SpreadsheetApp.getActiveSpreadsheet().getRangeByName("Proef") // 6 by 3;
var colors = [];
for (var row = 1; row <= selection.getNumRows(); ++row) {
var cell = selection.getCell(row, 1);
if (cell.isBlank()) {
colors[row, 1] = "#86d8b6";
}// if
else {
colors[row, 1] = "c4c4a4";
}// else
colors[row, 2] = "blue";
colors[row, 3] = "green";
}// for
SpreadsheetApp.getActiveSpreadsheet().
getRangeByName("Proef").setBackgrounds(colors);
}
When I use a Browser.msgBox . . to show me some values from the array. It is ok. But clearly setBackgroundColors wants an object and not an array.
The setBackgrounds expect the value in [][] and you are passing the values in []. Refer the below code.
function TabelMarkeren() {
var selection = SpreadsheetApp.getActiveSpreadsheet().getRangeByName("Proef") // 6 by 3;
var finalColors = [];
for (var row = 1; row <= selection.getNumRows(); ++row) {
var colors = [];
var cell = selection.getCell(row, 1);
if (cell.isBlank()) {
colors[row, 1] = "#86d8b6";
} // if
else {
colors[row, 1] = "c4c4a4";
} // else
colors[row, 2] = "blue";
colors[row, 3] = "green";
finalColors.push(colors)
} // for
Logger.log(colors)
SpreadsheetApp.getActiveSpreadsheet().getRangeByName("Proef").setBackgrounds(finalColors);
}
Thank you Ritz, I have it working now.
I also had to change the colomn indexes from 1,2,3 to 0,1,2. That was another mistake. The code is now:
function TabelMarkerenn() {
var selection = SpreadsheetApp.getActiveSpreadsheet().getRangeByName("Proef");
var finalColors = []
for (var row = 1; row <= selection.getNumRows(); ++row) {
var colors = [];
var cell = selection.getCell(row, 1);
if (cell.isBlank()) {
colors[row, 0] = "#86d8b6";
}// if
else {
colors[row, 0] = "#c4c4a4";
}// else
colors[row, 1] = "blue";
colors[row, 2] = "green";
finalColors.push(colors);
}// for
Logger.log(finalColors);
SpreadsheetApp.getActiveSpreadsheet().
getRangeByName("Proef").setBackgrounds(finalColors);
}
Very happy with this, but . . . isn't there a way to directly use the finalColors array? Or is that slower or just not common practice.
I have a spreadsheet for project data with time-sheet for each month logged against each project ID
I want to iterate through each sheet and if there is matching project ID , I want to sum up the number of hours logged for each project.
I have written the following code but keep getting the
TypeError: Cannot read property "0" from undefined. (line 31).
This is my sheet : https://goo.gl/rrsSxI
And this is my Code.
function TotalHours(TaskID) {
var a = SpreadsheetApp.getActiveSpreadsheet().getSheets().length;
var sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
var sum = 0;
// var fcol = 0;
for (var i = 1; i <= a; ++i) {
// var sheetname = sheets[i].getName();
//var cell = sheets[i].getActiveCell();
//Set active cell to A1 on each sheet to start looking from there
SpreadsheetApp.setActiveSheet(sheets[i])
//var sheet = sh.getActiveSheet();
var range = sheets[i].getRange("A1");
//* sheets[i].setActiveRange(range);
var data = sheets[i].getDataRange().getValues();
for (var row = 2; row <= data.length; ++row) {
if (data[row][0] == TaskID) {
for (var col = 2; col <= 31; ++col) {
sum += sheets[i].getRange(row, col).getValue();
}
}
}
}
return sum;
}
Can someone help me with what I am doing wrong.
I assume you want to exclude the sheet where the formula is going to be used ("Tracker" ?
See if this works ?
function TotalHours(TaskID) {
var sum = 0,
s = SpreadsheetApp.getActive(),
active = s.getActiveSheet().getName(),
sheets = s.getSheets();
for (var i = 0, slen = sheets.length; i < slen; i++) {
if(sheets[i].getName() != active) {
var sheetVal = sheets[i].getDataRange()
.getValues();
for (var j = 0, vlen = sheetVal.length; j < vlen; j++) {
if (sheetVal[j][0] == TaskID) {
for (var k = 2, rlen = sheetVal[j].length; k < rlen; k++) {
var c = sheetVal[j][k]
sum += c && !isNaN(parseFloat(c)) && isFinite(c)? c : 0; //check if cell holds a number
}
}
}
}
}
return sum;
}
I need to format numbers with commas as thousand seperators, for example:
1234 = 1,234
1234.50 = 1,234.50
12345.60 = 12,345.60
123456.70 = 123,456.70
1234567.80 = 1,234,567.80
etc etc
This needs to work for numbers with decimal values or without
i.e. both 1234567.80 and 1234567
This is for Actionscript 2 in a Coldfusion / Flash application, so normal actionscript is being used. I have seen a couple of solutions on the net but none quite do the trick.
So far I have the function below, but it is not formatting correctly when decimals are provided.For example: 21898.5 becomes 2,188,8.5.
Please could you help me find the bug or offer an alternative solution that fulfils the requriements.
Thanks
_global.NumberFormat = function(theNumber)
{
var myArray:Array;
var numberPart:String;
var decPart:String;
var result:String = '';
var numString:String = theNumber.toString();
if(theNumber.indexOf('.') > 0)
{
myArray = theNumber.split('.');
numberPart = myArray[0];
decPart = myArray[1];
}
else
{
numberPart = numString;
}
while (numString.length > 3)
{
var chunk:String = numString.substr(-3);
numString = numString.substr(0, numString.length - 3);
result = ',' + chunk + result;
}
if (numString.length > 0)
{
result = numString + result;
}
if(theNumber.indexOf('.') > 0)
{
result = result + '.' + decPart;
}
//alert('Result: ' + result);
return result;
}
You could try this:
_global.NumberFormat = function(numString)
{
numString = String(numString);
var index:Number = numString.indexOf('.');
var decimal:String;
if(index > 0) {
var splitByDecimal:Array = numString.split(".");
//return NumberFormat(splitByDecimal[0])+"."+splitByDecimal[1];
numString = splitByDecimal[0];
decimal = splitByDecimal[1];
} else if(index === 0) {
return "0"+numString;
}
var result:String = '';
while (numString.length > 3 ) {
var chunk:String = numString.substr(-3);
numString = numString.substr(0, numString.length - 3);
result = ',' + chunk + result;
}
result = numString + result;
if(decimal) result = result + "." + decimal;
return result;
}
It splits the number by the decimal if present(compensating for an illegal '.01234' if required), and uses recursion so call itself on the split element.
For your example numbers this traces:
1,234
1,234.50
12,345.60
123,456.70
1,234,567.80
Just for fun
This is why your original code didn't work:
After creating a string representation of the number (var numString:String = theNumber.toString();) you then carried on using the actual number rather than the string version.
After assigning a value to number part you then continued to perform operations on numString rather than numberPart.
A corrected version looks like this:
_global.NumberFormat = function(theNumber)
{
var myArray:Array;
var numberPart:String;
var decPart:String;
var result:String = '';
var numString:String = theNumber.toString();
if(numString.indexOf('.') > 0)
{
myArray = numString.split('.');
numberPart = myArray[0];
decPart = myArray[1];
}
else
{
numberPart = numString;
}
while (numberPart.length > 3)
{
var chunk:String = numberPart.substr(-3);
numberPart = numberPart.substr(0, numberPart.length - 3);
result = ',' + chunk + result;
}
if (numberPart.length > 0)
{
result = numberPart + result;
}
if(numString.indexOf('.') > 0)
{
result = result + '.' + decPart;
}
//alert('Result: ' + result);
return result;
}
public static function formatNumberString(value:Number,separator:String):String {
var result:String = "";
var digitsCount:Number = value.toString().length;
separator = separator || ",";
for (var i:Number = 0; i < digitsCount; i++) {
if ((digitsCount - i) % 3 == 0 && i != 0) {
result += separator;
}
result += value.toString().charAt(i);
}
return result;
}
Try this out, works fine for me:
var largeNumber:String=new String(1000000.999777);
var fAr:Array=largeNumber.split(".");
var reg:RegExp=/\d{1,3}(?=(\d{3})+(?!\d))/;
while(reg.test(fAr[0]))
fAr[0]=fAr[0].replace(reg,"$&,");
var res:String=fAr.join(".");
trace(res);
Trace: 1,000,000.999777
