I want to work with ".xls" files, however EPPlus produces an error when I try to read the ".xls" file.
this my code:
System.IO.Stream stream;
ExcelSpreadsheetName sheeet;
FileUploadBuild fileUpload;
DialogGroup dlgUploadGroup;
FileUploadBuild fileUploadBuild;
FormBuildControl formBuildControl;
Dialog dialog = new Dialog("Import the data from Excel");
dlgUploadGroup = dialog.addGroup("@SYS54759");
formBuildControl = dialog.formBuildDesign().control(dlgUploadGroup.name());
fileUploadBuild = formBuildControl.addControlEx(classstr(FileUpload), 'Upload');
fileUploadBuild.style(FileUploadStyle::MinimalWithFilename);
fileUploadBuild.fileTypesAccepted('.xls');
if (dialog.run() && dialog.closedOk())
{
FileUpload fileUploadControl = dialog.formRun().control(dialog.formRun().controlId('Upload'));
FileUploadTemporaryStorageResult fileUploadResult = fileUploadControl.getFileUploadResult();
if (fileUploadResult != null && fileUploadResult.getUploadStatus())
{
stream = fileUploadResult.openResult();
using (ExcelPackage Package = new ExcelPackage(stream))
{
int rowCount, i;
Package.Load(stream);
ExcelWorksheet worksheet = package.get_Workbook().get_Worksheets().get_Item(1);
OfficeOpenXml.ExcelRange range = worksheet.Cells;
rowCount = worksheet.Dimension.End.Row - worksheet.Dimension.Start.Row 1;
for (i = 2; i<= rowCount; i )
{
info(range.get_Item(i, 1).value);
info(range.get_Item(i, 2).value);
}
}
}
else
{
error("Error here");
}
I'm wondering whether there is another approach to work with "xls" files.
I saw several code snippets that use SysExcelWorkbook, but they fail with the error "The name 'SysExcelApplication' does not denote a class, a table, or an extended data type."
SysExcelApplication application;
SysExcelWorkbooks workbooks;
SysExcelWorkbook workbook;
SysExcelWorksheets worksheets;
SysExcelWorksheet worksheet;
SysExcelCells cells;
COMVariantType type;
int row;
ItemId itemid;
Name name;
FileName filename;
;
application = SysExcelApplication::construct();
workbooks = application.workbooks();
//specify the file path that you want to read
filename = @"C:\Users\hsaoudi\Downloads\crypresenceetcoutparemploye.xls";
try
{
workbooks.open(filename);
}
catch (Exception::Error)
{
throw error("File cannot be opened.");
}
workbook = workbooks.item(1);
worksheets = workbook.worksheets();
worksheet = worksheets.itemFromNum(1);
cells = worksheet.cells();
do
{
row ;
itemId = cells.item(row, 1).value().bStr();
name = cells.item(row, 2).value().bStr();
info(strfmt('%1 - %2', itemId, name));
type = cells.item(row 1, 1).value().variantType();
}
while (type != COMVariantType::VT_EMPTY);
application.quit();
