    <p>I have an excel file on a server. I access it with a path looking like this : "\\Server\folder\file.xlsx".</p> <p>I was able to read it with the Excel API from office, but since I cannot install office on my server, I need to avoid this dependency.</p> <p>I tried using some other libraries, but it does not work...</p> <p>I tried opening the file with EPPLUS, but I have an exception saying " This operation is not supported for a relative URI" when I try to open the workbook... I tried with ExcelLibrary, but I have an out of memory exception...</p> <pre><code>//EXCELLIBRARY Workbook book = Workbook.Load(_filename); //EPPLUS FileInfo file = new FileInfo(_filename); ExcelPackage pack = new ExcelPackage(file); ExcelWorksheet sheet = pack.Workbook.Worksheets[1]; </code></pre> <p>Does someone have an idea on how to solve this?</p> <p>If not, you have another library to suggest? I don't want to use OleDB and already tried NOPI. I want a library that only need to add a reference to a dll. I need to open excel 2010 files. I also need to be able to determine what is the used range in the sheet and get a array with the values. Here is the code that I used and worked with the office API.</p> <pre><code>Excel.Application xlApp; Excel.Workbook xlWorkBook; Excel.Worksheet xlWorkSheet; object misValue = System.Reflection.Missing.Value; xlApp = new Excel.ApplicationClass(); xlWorkBook = xlApp.Workbooks.Open(_filename, 0, true, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0); xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1); _range = (System.Array)xlWorkSheet.UsedRange.Value2; _headers = GetHeaders(_range); _lastRow = xlWorkSheet.Cells.Find("*", misValue, misValue, misValue, Excel.XlSearchOrder.xlByRows, Excel.XlSearchDirection.xlPrevious, false, misValue, misValue).Row; xlWorkBook.Close(false, misValue, misValue); xlApp.Quit(); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
