I'm having problems saving new rows in my existing Excel file, it throws an exception and says "write-protected". My Excel file is not open or something I created it with this code and saved it.
...
xlWorkBook.SaveAs(path, Excel.XlFileFormat.xlWorkbookDefault, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
Marshal.ReleaseComObject(xlWorkSheet);
Marshal.ReleaseComObject(xlWorkBook);
Marshal.ReleaseComObject(xlApp);

endState = 7;

Maybe I cant save it because it's open while I opened it to change it. So delete and save again maybe? or just save like you would save it after adding a row more in a normal Excel file and close it.
if (System.IO.File.Exists(path))
{

This is a code which could create only create xls file. But I want to create xlsx (Excel) file; how can I do that from this code or else can I have another code which I could use to create xlsx files.
using Excel = Microsoft.Office.Interop.Excel;
using System.Runtime.InteropServices;
Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
if (xlApp == null)
{
MessageBox.Show("Excel is not properly installed!!");
return;

xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet.Cells[1, 1] = "ID";
xlWorkSheet.Cells[1, 2] = "Name";
xlWorkSheet.Cells[2, 1] = "1";
xlWorkSheet.Cells[2, 2] = "One";

Take a look on EasyXLS. It is a library that creates xlsx files.
ExcelDocument workbook = new ExcelDocument(1);
// Set the sheet name
workbook.easy_getSheetAt(0).setSheetName("Sheet1");
// Add data
ExcelTable xlsTable = ((ExcelWorksheet)workbook.easy_getSheetAt(0)).easy_getExcelTable();
xlsTable.easy_getCell(0, 0).setValue("ID");
xlsTable.easy_getCell(0, 1).setValue("Name");
xlsTable.easy_getCell(1, 0).setValue("1");
xlsTable.easy_getCell(1, 1).setValue("One");
xlsTable.easy_getCell(2, 0).setValue("2");
xlsTable.easy_getCell(2, 1).setValue("Two");
// Create Excel file
workbook.easy_WriteXLSXFile("d:\\vdfgdfg.xlsx");

Try OpenXML library, should do the trick, find more at

P.s. Interop won't work unless excel is installed on the machine.
Take a look at my SwiftExcel library. It was design for quick and easy excel output and what is more important - performance.
using (var ew = new ExcelWriter("C:\\temp\\test.xlsx"))

ew.Write("ID", 1, 1);
ew.Write("Name", 2, 1);

Replace the following line:

I have 2 textbox i.e. textbox1,textbox2
I want to export the data from these textboxes to an excel sheet i.e. test.xlsx
using a button.
Anyone know what's the code to do that?
First, you need to add a reference to the Excel Object Library in your project.
You can than import the library to your form:
using Excel = Microsoft.Office.Interop.Excel;
You can add similar code to this:
var excelApp = new Excel.Application();
excelApp.Workbooks.Open(filePath);
Excel._Worksheet workSheet = (Excel.Worksheet)excelApp.ActiveSheet;
workSheet.Cells[1, "A"] = textBox1.Text;
workSheet.Cells[1, "B"] = textBox1.Text;
You can also check this Walkthrough for an detailed explanation
Microsoft.Office.Interop.Excel.Workbook xlWorkBook;
Microsoft.Office.Interop.Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
string myPath = tbFolderpath.Text + tbFileName.Text;//User Given Path Value
FileInfo fi = new FileInfo(myPath);
Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application();
if (!fi.Exists)//To Check File exist in a location,if not exist it will create new file
{
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
xlWorkSheet.Cells[1, "A"] = "Name";
xlWorkSheet.Cells[1, "B"] = "Age";
xlWorkSheet.Cells[1, "C"] = "CurrentTime";
var columnHeadingsRange = xlWorkSheet.Range[xlWorkSheet.Cells[1, "A"],
xlWorkSheet.Cells[1, "C"]];
columnHeadingsRange.Interior.Color = Excel.XlRgbColor.rgbYellow;//To Give Header Color
xlWorkBook.SaveAs(myPath, Microsoft.Office.Interop.Excel.XlFileFormat.xlOpenXMLWorkbook,
misValue,misValue, misValue, misValue,
Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlExclusive,
misValue, misValue, misValue, misValue, misValue);
}
//Already File Exist it will open the File and update the data into excel`enter code here`
var workbook = xlApp.Workbooks.Open(myPath);
xlWorkSheet = (Excel.Worksheet)workbook.Worksheets.get_Item(1);
int _lastRow = xlWorkSheet.Range["A" +xlWorkSheet.Rows.Count].
End[Excel.XlDirection.xlUp].Row + 1;
xlWorkSheet.Cells[_lastRow, "A"] = Textbox1.Text;
xlWorkSheet.Cells[_lastRow, "B"] = Textbox2.Text;
DateTime currentTime = DateTime.Now;//To Get the Current Time
string formattedTime = currentTime.ToString("dd/MM/yyyy-hh:mm:ss");
xlWorkSheet.Cells[_lastRow, "C"] = formattedTime;
workbook.Save();
workbook.Close();
xlApp.Quit();
I have wrote the following code for exporting my local database data to an excel file. The fact is that it is working properly, but I'd only like to export it with the actual date, or just month, like august, or something like that. Besides that, the problem that really matters is that it replaces every time the previously exported excel file. How can I change this thing? Thanks !

If you don't want it to overwrite the same workbook every time then you'll need to specify a different file name rather than hard coding it in.
Something simple like creating the filename with the current datetime would normally be sufficient (you can change the format to suit you):
string fileName = #"db " + DateTime.Now.ToString("dd-MM-yyyy HH-mm-ss") + #".xls";
string filePath = Path.Combine(#"C:\Users\Andrei\Documents\Visual Studio 2010\Projects\Stellwag\Stellwag", fileName);
xlWorkBook.SaveAs(filePath, Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
This would produce a file like this:
db 01-09-2015 10-32-35.xls
There is still not explicit check to see if the file exists, but unless you're clicking it every second it's unlikely to overwrite.

int currentLine = 1;
foreach (int currentKey in currentLogFile.Keys)
{

xlWorkSheet.Cells[currentLine, 2] = currentLogFile[currentKey];
currentLine++;

chartRange = xlWorkSheet.get_Range("A1", "B10");
chartPage.SetSourceData(chartRange, misValue);
chartPage.ChartType = Microsoft.Office.Interop.Excel.XlChartType.xlLine;

Try it with xlWorkSheet.UsedRange.EntireRow.Height = value; but it doesn't work. autoFit() is working but i would like to work with my value.
I think you may be looking for RowHeight...
