using namespace System;
using namespace EasyXLS;
using namespace EasyXLS::Constants;

int main()
    Console::WriteLine("Tutorial 18\n----------\n");

    // Create an instance of the class that exports Excel files having two sheets
    ExcelDocument ^workbook = gcnew ExcelDocument(2);

    // Set the sheet names
    workbook->easy_getSheetAt(0)->setSheetName("First tab");
    workbook->easy_getSheetAt(1)->setSheetName("Second tab");

    // Get the table of data for the first worksheet
    ExcelWorksheet ^xlsFirstTab = safe_cast<ExcelWorksheet^>(workbook->easy_getSheetAt(0));
    ExcelTable ^xlsFirstTable = xlsFirstTab->easy_getExcelTable();

    // Add data in cells for report header
    for (int column=0; column<5; column++)
        xlsFirstTable->easy_getCell(0,column)->setValue(String::Concat("Column ",(column + 1).ToString()));

    // Add data in cells for report values
    for (int row=0; row<100; row++)
        for (int column=0; column<5; column++)
                String::Concat("Data ", (row + 1).ToString(), ", ", (column + 1).ToString()));

    // Set column widths
    xlsFirstTable->setColumnWidth(0, 70);
    xlsFirstTable->setColumnWidth(1, 100);
    xlsFirstTable->setColumnWidth(2, 70);
    xlsFirstTable->setColumnWidth(3, 100);
    xlsFirstTable->setColumnWidth(4, 70);

    // Freeze row
    xlsFirstTable->easy_freezePanes(1, 0, 75, 0);

    // Export Excel file
    Console::WriteLine("Writing file C:\\Samples\\Tutorial18 - freeze rows or columns in Excel.xlsx.");
    workbook->easy_WriteXLSXFile("C:\\Samples\\Tutorial18 - freeze rows or columns in Excel.xlsx");

    // Confirm export of Excel file
    String ^sError = workbook->easy_getError();
    if (sError->Equals(""))
        Console::Write("\nFile successfully created. Press Enter to Exit...");
        Console::Write(String::Concat("\nError encountered: ", sError, "\nPress Enter to Exit..."));

    // Dispose memory
    delete workbook;
