The Time value is not reflecting correctly in my excel worksheet

I managed to create an Excel file and tried to update the current system timings into first cell of the worksheet. But when the file is created, I get wrong values for timings. I want the current system time but it is displaying 12:00:00 However date is being displayed correctly.
I am using Microsoft Excel 12.0 Object Library. I need help to get the current system timings or need to reflect the timings as per the date time picker.
Here is my code:
namespace Test6attendance
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.Application();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet.Cells[1, 1] = DateTime.Now.Date.ToString("MM/dd/ yyyy, hh:mm:ss tt");
xlWorkBook.SaveAs("D:\\login.xlscsharp-Excel.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
MessageBox.Show("Excel file created , you can find the file D:\\csharp-Excel.xls");
}
private void releaseObject(object obj)
{
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
obj = null;
}
catch (Exception ex)
{
obj = null;
MessageBox.Show("Exception Occured while releasing object " + ex.ToString());
}
finally
{
GC.Collect();
}
}
}
}

It is because of the following line:
xlWorkSheet.Cells[1, 1] = DateTime.Now.Date.ToString("MM/dd/ yyyy, hh:mm:ss tt");
DateTime.Now.Date will set the time property to Midnight. Use this Instead
xlWorkSheet.Cells[1, 1] = DateTime.Now.ToString("MM/dd/ yyyy, hh:mm:ss tt");
Here is the DateTime.Now Property, DateTime.Date Property

Export datagrid to Excel using Dialog Box on Winform

I'm looking for how to export a datagrid (or dataSet) (not datagridview) to Excel using dialog box which saves data in specific place, I am working on VS 2003 Winform not Webform.
This is my code:
I just need too open a dialog box to let the user choose where he wants to put his file:
private void button2_Click(object sender, System.EventArgs e)
{
#region
string data = null;
int i = 0;
int j = 0;
Excel.Application xlApp ;
Excel.Workbook xlWorkBook ;
Excel.Worksheet xlWorkSheet ;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.ApplicationClass();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
for (i = 0; i <= dsSelectionListeDiffere.Tables[0].Rows.Count - 1; i++)
{
for (j = 0; j <= dsSelectionListeDiffere.Tables[0].Columns.Count - 1; j++)
{
data = dsSelectionListeDiffere.Tables[0].Rows[i].ItemArray[j].ToString();
xlWorkSheet.Cells[i + 1, j + 1] = data;
}
}
xlWorkBook.SaveAs("csharp.net-informations.xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
MessageBox.Show("Excel file created , you can find the file c:\\csharp.net-informations.xls");
#endregion
}
and i have another code it works too :
#region
//// lblMessage.Visible = true;
//// lblMessage.Text = "";
// // Export all the details
// try
// {
// // Get the datatable to export
// DataTable dt = dsSelectionListeDiffere.Tables[0].Copy();
// dsSelectionListeDiffere = FrmFonctionPrincipale.getListeDifferesParClient(1);
// // Export all the details to Excel
//
//
// RKLib.ExportData.Export objExport = new RKLib.ExportData.Export("Win");
// objExport.ExportDetails(dt, Export.ExportFormat.Excel, "C:\\EmployeesInfo.xls");
// MessageBox.Show("Exporté Avec Succès dans C:\\EmployeesInfo.xls");
// }
// catch(Exception Ex)
// {
// MessageBox.Show(Ex.Message);
//// lblMessage.Text = Ex.Message;
// }
#endregion

If you don't need to change the filename, but only the folder where this file is saved, then you can use the FolderBrowserDialog to ask just the folder where the file will be saved
private void button2_Click(object sender, System.EventArgs e)
{
FolderBrowserDialog fbd = new FolderBrowserDialog();
fbd.Description = "Select the destination folder";
fbd.ShowNewFolderButton = true;
fbd.RootFolder = Environment.SpecialFolder.Personal;
if( fbd.ShowDialog() == DialogResult.OK )
{
string folderName = fbd.SelectedPath;
.... the rest of your excel export code .....
// Pass the full path to the SaveAs method
string fullPathName = Path.Combine(folderName, "csharp.net-informations.xls");
xlWorkBook.SaveAs(fullPathName, .....);
.....
MessageBox.Show("Excel file created , you can find the file in: " + fullPathName);
}
If you need to change also the file name, then you need to use a SaveFileDialog instance.
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Excel files (*.xls)|*.xls|All files (*.*)|*.*" ;
sfd.FilterIndex = 1 ;
sfd.RestoreDirectory = true ;
sfd.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
if(sfd.ShowDialog() == DialogResult.OK)
{
if(sfd.FileName.Length > 0)
{
... the rest of your excel code here ....
// sfd.FileName already contains the full path so
xlWorkBook.SaveAs(sfd.FileName, .....);
}
}
else
{
if(MessageBox.Show("Are you sure you want to quit without saving?", "Quitting",
MessageBoxButtons.YesNo) == DialogResult.No)
{
// This important to stop the Form to close if this button is the Cancel/AcceptButton
// or its property DialogResult is not DialogResult.None
this.DialogResult = DialogResult.None;
}
}

I'm working on VS 2003 C# WINFORM.

Excel worksheet change event is not firing

I have created excel workbook using .NET interop. The excel workbook is created successfully through my C# code. When the user makes any changes in the excel, I want to do some stuff. I have used the ExcelWorkSheet.Change event. But this event is not firing. Here is my code-
using Excel = Microsoft.Office.Interop.Excel;
public class xxx
{
static Excel.Application xlApp;
static Excel.Workbook xlWorkBook;
static Excel.Worksheet xlWorkSheet;
static Excel.Worksheet xlWorkSheet1;
static Excel.DocEvents_ChangeEventHandler EventDel_CellsChange;
public static void ExportToExcel()
{
xlApp = new Excel.ApplicationClass();
object misValue = System.Reflection.Missing.Value;
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet1 = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(2);
---------------- data is dumped to the excel here----------------
((Microsoft.Office.Interop.Excel._Worksheet)xlWorkSheet).Activate();
xlApp.EnableEvents = true;
EventDel_CellsChange = new Excel.DocEvents_ChangeEventHandler(Worksheet_Change);
xlWorkSheet.Change += EventDel_CellsChange;
xlWorkBook.SaveAs("D:\\Test.xlsx", Excel.XlFileFormat.xlWorkbookDefault, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlShared, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet1);
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
response.ClearContent();
response.Clear();
response.ContentType = "application/vnd.ms-excel";
response.AddHeader("Content-Disposition", "attachment; filename=Test.xlsx;");
response.TransmitFile(("D:\\Test.xlsx");
response.Flush();
response.End();
}
public static void Worksheet_Change(Excel.Range Target)
{
try
{
xlApp.EnableEvents = false;
Excel.Range range = xlWorkSheet.get_Range("Y2");
range.Formula = "=A2";
}
catch (Exception ex)
{
}
finally
{
xlApp.EnableEvents = true;
}
}
}
No change is reflected in the Excel file when the user makes some changes.
Please help me out.
Thanks in advance

The Worksheet_Change event is not global - it only applies to that particular worksheet. In your code you wire up the event handler to the xlSheet1.Change event, then close the workbook and release all the Excel objects.
EDIT: I popped your code behind a Form and adapted it slightly. I could get the event to fire and the formula in cell Y2 is set. I'm not 100% sure of your circumstances, but try this code and then compare with your own. Hope it helps.
public partial class Form1 : Form
{
private static Excel.Application xlApp;
private static Excel.Workbook xlWorkBook;
private static Excel.Worksheet xlWorkSheet;
private static Excel.Worksheet xlWorkSheet1;
private static Excel.DocEvents_ChangeEventHandler EventDel_CellsChange;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
xlApp = new Excel.Application();
xlApp.Visible = true;
object misValue = System.Reflection.Missing.Value;
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet1 = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(2);
//---------------- data is dumped to the excel here----------------
((Microsoft.Office.Interop.Excel._Worksheet)xlWorkSheet).Activate();
xlApp.EnableEvents = true;
EventDel_CellsChange = new Excel.DocEvents_ChangeEventHandler(Worksheet_Change);
xlWorkSheet.Change += EventDel_CellsChange;
}
public static void Worksheet_Change(Excel.Range Target)
{
try
{
xlApp.EnableEvents = false;
Excel.Range range = xlWorkSheet.get_Range("Y2");
range.Formula = "=A2";
}
catch (Exception ex)
{
}
finally
{
xlApp.EnableEvents = true;
}
}

How To send datagrid in function

I want to export datagrid information to excel file.My Problem is that i need to rewrite the same function in each windowsfrom that i want to export.
Is it possible to sent the datagrid information to Main function??
the code is:
private void button2_Click(object sender, EventArgs e)
{
string name = textBox1.Text;
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.Application();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
int i = 0;
int j = 0;
for (i = 0; i <= dgvCostumers.RowCount - 1; i++)
{
for (j = 0; j <= dgvCostumers.ColumnCount - 1; j++)
{
DataGridViewCell cell = dgvCostumers[j, i];
xlWorkSheet.Cells[i + 1, j + 1] = cell.Value;
}
}
xlWorkBook.SaveAs(name + ".xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
MessageBox.Show("Excel file created , you can find the file c:\\my documents\\" + name + ".xls");
textBox1.Text = "";
textBox1.Visible = false;
button1.Visible = true;
label2.Visible = false;
}
}
private void releaseObject(object obj)
{
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
obj = null;
}
catch (Exception ex)
{
obj = null;
MessageBox.Show("Exception Occured while releasing object " + ex.ToString());
}
finally
{
GC.Collect();
}
}

How about something like
private void DataGridViewToExcel(string name, DataGridView dgv)
{
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.Application();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
int i = 0;
int j = 0;
for (i = 0; i <= dgv.RowCount - 1; i++)
{
for (j = 0; j <= dgv.ColumnCount - 1; j++)
{
DataGridViewCell cell = dgv[j, i];
xlWorkSheet.Cells[i + 1, j + 1] = cell.Value;
}
}
xlWorkBook.SaveAs(name + ".xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
}
and then your button click code can change to something like
private void button2_Click(object sender, EventArgs e)
{
string name = textBox1.Text;
DataGridViewToExcel(name, dgvCostumers);
MessageBox.Show("Excel file created , you can find the file c:\\my documents\\" + name + ".xls");
textBox1.Text = "";
textBox1.Visible = false;
button1.Visible = true;
label2.Visible = false;
}
}
