So that Once I read I can send them to DataBase. My excel file Test.xls in ("C:\") Thanks DossAnswer 2 I would guess: open Excel from your program, and have Excel read the data. Search for Visual Studio Tools for Office (VSTO) for the details. Answer 3 His Doss, Create a reference in your project to excel Objects Library. The exc el object library can be added in the COM tab of adding reference dialog. I hope the following code in your menu click event method will help you a lot to achi eve your need. this.openFileDialog1.FileName = "*.xls"; if (this.openFileDialog1.ShowDialog() == DialogResult.OK) { Excel.Workbook theWorkbook = ExcelObj.Workbooks.Open( openFileDialog1.FileName, 0, true, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true); Excel.Sheets sheets = theWorkbook.Worksheets; Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1); for (int i = 1; i //definition of worksheet is Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1); int stemp = Convert.ToInt32 ( worksheet.Cells[1, 1]); Regards Harshal Answer 31 Hi, did you find out a way to dynamically insert a button in excel and get your c# method to be called when the button is clicked? Answer 32Hello, I will refer here only the Web Applications. It is not possible to perform file I / O operations at Web Applications. Although you can read Excel files on .csv / .txt format. You can find an example on my site: http://www.wwv-it.com/WebServicesNet/ServicesNet.aspx, category Data conversions ,Service "Convert Excel / Text files to data Sets / XML files / database tables ". I would be glad if you could help with this example. Do not hesitate to contact me if you need more information or code.

To use this I need to add the microsoft Excel refrence to the project, right? The thing is I dont have microsoft offince on my computer. I use open office whi ch is kind of the same thing. But the problem is that I dont have that refrence in the com that when I want to add the refrence to my project. Is there any oth er way to do this or anywhere I can get that reference thing? thx Answer 38 Does anybody know to figure out what range of data was used for a chart object?I like this bit of code posted earlier because it is easy to use: Range myRange = (Range) sheets.Cells[30,10]; currentRate = (float)Convert.ToDouble(myRange.Cells.Value2.ToString()); myRange = (Range)sheets.Cells[30, 2];So, my plan is to figure out which cells were used to create a particular chart - i.e. which cells are the x-axis and which cells are the y-axis. Then just loo p through and grab the values to an array.Any thought would be great...Answer 39 learning Answer 40 I cannot find the function ConvertToStringArray. What dll do I need to include in my project to be able to use this function?Answer 41 This is not ready made function, you have to write it yourself, here i can give u example, you can ajust the lengths acooring to your need, string[] ConvertToStringArray(System.Array values) { // create a new string array string[] theArray = newstring[values.Length]; int position = 0; // loop through the 2-D System.Array and populate the 1-D String Array for (int i = 1; i
