I'm working with xls file. How can I save it (if exist) with the same file name + "(copy 1)" like Windows desktop.
method saveCommande(...)
if(!Directory.Exists(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "EE_Commande_Fournisseur"))
{
Directory.CreateDirectory(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\EE_Commande_Fournisseur");
}
xlWorkBook.SaveAs("EE_Commande_Fournisseur\\" + path, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, true, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
path = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\EE_Commande_Fournisseur\\" + path;
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
this.ReleaseComObject(xlApp,xlWorkBook);
//sauvergarde dans la base de données
_newAchatCommande.path = path;
this._fileName = path;
contexte.AddToAchatCommande(_newAchatCommande);
contexte.SaveChanges();
thanks
try using File object's Exists method:
if (!System.IO.File.Exists(#"C:\test2.xls"))
{
xlWorkBook.SaveAs(#"c:\test2.xls");
}
else
{
xlWorkBook.SaveAs(#"c:\test2(Copy).xls");
}
Or Alternatively you can overwrite your excel file by
Microsoft.Office.Interop.Excel.Application excel = new Microsoft.Office.Interop.Excel.Application();
excel.DisplayAlerts = false;
excelSheePrint.SaveAs(filename, Microsoft.Office.Interop.Excel.XlFileFormat.xlWorkbookDefault, Type.Missing, Type.Missing, true, false, XlSaveAsAccessMode.xlNoChange, XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing);
Note: It will overwrite the existing excel (if exist) without asking the user.
DataTable dt= dtData;
using (XLWorkbook wb = new XLWorkbook())
{
//Range(int firstCellRow,int firstCellColumn,int lastCellRow,int lastCellColumn)
int CCount = dt.Columns.Count;
int RCount = dt.Rows.Count;
var ws = wb.Worksheets.Add("Report"); //add worksheet to workbook
ws.Row(1).Cell(1).RichText.AddText(ReportName);
ws.Range(1, 1, 1, CCount).Merge();
ws.Range(1, 1, 1, CCount).Style.Font.Bold = true;//Range(int firstCellRow,int firstCellColumn,int lastCellRow,int lastCellColumn)
ws.Range(1, 1, 1, CCount).Style.Font.FontSize = 16;
ws.Range(1, 1, 1, CCount).Style.Alignment.Horizontal = XLAlignmentHorizontalValues.Center;
ws.Range(1, 1, 1, CCount).Style.Alignment.Vertical = XLAlignmentVerticalValues.Center;
//ws.Range("A1:Z1").Style.Font.Bold = true;
ws.Row(2).Cell(1).InsertTable(dt);
ws.Range("A2:Z2").Style.Font.Bold = true;
ws.Range(2, 1, RCount + 2, CCount).Style.Border.OutsideBorder = XLBorderStyleValues.Medium;
wb.SaveAs(FolderPath + filename + ".xlsx");
ws.Dispose();
}
it works!
thanks

I have a datagrid on my visual studio with 40 items. On button click I want the first 30 items to display on my excel template and the balance to go to page two of template.

Please help as this works but on line 31 it ovewrites the clauses on template. I want it must continue to page two.
My code works fine with generating an excel file, thanks to this community here.
But I still have a problem:
I have a ListBox from which I export a data to an excel file.
When I run it and the file will be created, I open it and in the rows I see
"SheduleMenager.Employees"
Employees is the class in my project in which i have two properties:
string Name and bool Experience
Here is a button to create and fill up the excel file :
private void Generateexcelfile_Click(object sender, RoutedEventArgs e)
{
Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
for (int i = 0; i < MonBox.Items.Count; i++)
{
xlWorkSheet.Cells[i + 1, 1] = MonBox.Items[i].ToString();
}
xlWorkBook.SaveAs("FILEPATH", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
}
I would be really happy if you can help me to represent a VALUE of Employees.Name
I'm guessing that MonBox contains list of employees, in Items collection.
If that is so, change your line
xlWorkSheet.Cells[i + 1, 1] = MonBox.Items[i].ToString();
into
xlWorkSheet.Cells[i + 1, 1] = (MonBox.Items[i] as SheduleMenager.Employees).Name;
I am a little new to c# and Visual Studio and I am trying to plot a graph based on the values of a csv file located somewhere else. I have used the ChartObjects and ChartWizard property in c# to create the graph. The graph plotted should be the column range I am providing, in the Y-axis and X-axis should have the current row number(1,2,3,4 etc). However my graph by default takes the X-axis to be the first column in my csv file. It plots properly if I specify a range for X-axis too but how can I get the current row number there?
I went through a lot of articles and questions even on Stack Overflow but none seemed to help.
Here's a snippet of my code:
Microsoft.Office.Interop.Excel.Application xlexcel;
Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlexcel = new Microsoft.Office.Interop.Excel.Application();
var xlWorkBooks = xlexcel.Workbooks;
xlexcel.Visible = false;
xlWorkBooks.OpenText(#"C:\" + processName + ".csv", misValue, misValue, Microsoft.Office.Interop.Excel.XlTextParsingType.xlDelimited, Microsoft.Office.Interop.Excel.XlTextQualifier.xlTextQualifierNone, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue, misValue);
// Set Sheet 1 as the sheet you want to work with
xlWorkSheet = (Microsoft.Office.Interop.Excel.Worksheet)xlWorkBooks[1].Worksheets.get_Item(1);
xlWorkSheet.Shapes.AddChart(misValue, misValue, misValue, misValue, misValue).Select();
//~~> Make it a Line Chart
xlexcel.ActiveChart.ApplyCustomType(Microsoft.Office.Interop.Excel.XlChartType.xlLine);
//~~> Set the data range
xlexcel.ActiveChart.SetSourceData(xlWorkSheet.Range["E2:E200"]);
xlexcel.ActiveChart.ChartWizard(misValue, Title: chartName + " (" + processName + ")", CategoryTitle: "Iterations", ValueTitle: processType);
Microsoft.Office.Interop.Excel.ChartObjects chartObjects =(Microsoft.Office.Interop.Excel.ChartObjects)(xlWorkSheet.ChartObjects(Type.Missing));
foreach (Microsoft.Office.Interop.Excel.ChartObject co in chartObjects)
{
co.Select();
Microsoft.Office.Interop.Excel.Chart chart = (Microsoft.Office.Interop.Excel.Chart)co.Chart;
chart.Export(ConfigurationManager.AppSettings.Get("Charts") + "\\ProcessFiles" + #"\" + chartName + " (" + processName + "of" + processType + ")" + ".png", "PNG", false);
co.Delete();
}
xlWorkBooks[1].Close(true, misValue, misValue);
xlexcel.Quit();
Any guidance would be greatly appreciated.
Thanks!

I want to make a button which you press for passing data from 3 textboxes to an excel table but I want to use the same table every time and just add data to a new row. Every time I want to add something, it creates me a new excel file. Here's my code.
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet.Cells[1, 1] = "Book name";
xlWorkSheet.Cells[1, 2] = "Author";
xlWorkSheet.Cells[1, 3] = "Rating";
string curFile = #"g:\Biblioteca.xls";
if (!File.Exists(curFile))
{
xlWorkBook.SaveAs("g:\\Biblioteca.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkSheet.Cells[++k, 1] = getName;
xlWorkSheet.Cells[k, 2] = getAuthor;
xlWorkSheet.Cells[k, 3] = getRating;
MessageBox.Show("Excel created succesfuly");
}
else
{
Excel.Application excelApp = (Excel.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Excel.Application");
Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(curFile,
0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "",

You are not opening any existing file!
See #gmiley's second reference for an example of opening an existing spreadsheet. You may need to study Range to work out how to place your new data.
I am creating a dynamic Excel sheet using ExcelWorksheet. I need to create a non-editable excel. ws.Cells["A1:Q12"].Style.Locked = true is not working.
Here is my code :
Default.aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
string filePath = Server.MapPath("~/Download/Sample.xlsx");
using (ExcelPackage pck = new ExcelPackage())
{
FileInfo summaryFilePath = new FileInfo(filePath);
ExcelWorksheet ws= pck.Workbook.Worksheets.Add("Sample Page");
CreateForamters(ws);
}
}
private void CreateForamters(ExcelWorksheet ws)
{
ws.Cells["B8:L8"].Value = "SamplePage";
ws.Cells["B10:L10"].Value = DateTime.Now.ToString("MMM-yy");
ws.Cells["B11:L11"].Value = "test data........-";
ws.Cells["B8:L11"].Style.Fill.PatternType = ExcelFillStyle.Solid;
ws.Cells["B8:L11"].Style.Font.Bold = true;
ws.Cells["B8:L11"].Style.Font.Name = "Arial";
ws.Cells["B8:L11"].Style.Font.Size = 16;
ws.Cells["B8:L11"].Style.Font.Color.SetColor(Color.Blue);
ws.Cells["B8:L11"].Style.Fill.BackgroundColor.SetColor(Color.White);
ws.Cells["B8:L11"].Style.HorizontalAlignment = OfficeOpenXml.Style.ExcelHorizontalAlignment.Center;
ws.Cells["B8:L8"].Merge = true;
ws.Cells["B9:L9"].Merge = true;
ws.Cells["B10:L10"].Merge = true;
ws.Cells["B11:L11"].Merge = true;
ws.Cells["A1:Q12"].Style.Locked = true;
}
Thank you all in advance for your response.
I am creating a dynamic Excel sheet using ExcelWorksheet. I need to create a non-editable excel. ws.Cells["A1:Q12"].Style.Locked = true is not working.
To create NON-Editable Cells, you have to use
ws.get_Range("A1", "Q12").Locked = true;
And then you need to protect the worksheet. Without protecting the worksheet, the .Locked command doesn't have any significance.
Here is a basic example (TRIED AND TESTED IN VS2010 + OFFICE 2010)
object misValue = System.Reflection.Missing.Value;
ws.get_Range("A1", "Q12").Locked = true;
string Password = "Sid";
ws.Protect(Password, misValue, misValue, misValue, misValue, misValue,
misValue, misValue, misValue, misValue, misValue, misValue, misValue,
misValue, misValue, misValue);
NOTE: By default all cells in Excel are locked. If you don't want to protect the rest of the cells in the sheet then remember to set their .Locked property to False.
ws.Cells.Locked = false;
and then use the above code.
if you want to save Excel WorkBook as ReadOnly Save as Below:
object misValue = System.Reflection.Missing.Value;
ExcelWorkBook.ActiveWorkbook.SaveAs(save_path, Excel.XlFileFormat.xlWorkbookNormal, misValue , misValue , True, True,XlSaveAsAccessMode.xlShared, false, false, misValue, misValue , misValue );
