    <p>I have a file upload control in my asp.net (c#) website, which is used to upload csv files with data to be inserted into the database, my problem is that, I was not able to get the actual path of the uploaded file</p> <p>It always gave me: <code>C:\inetput\projectfolder\csvname.csv</code> where it should have been similar to: <code>C:\Documents and settings\Pcname\Desktop\csvname.csv</code></p> <p>but by going through the various post of file upload, i came to know that file need to be saved on the server first,</p> <p>using <code>Fileupload1.Saveas(savepath);</code></p> <p>which is mandatory to save the file in a previously specified location, where this not actually required. (since it will increase the overhead of again deleting the file).</p> <p>then what I do is as below:</p> <pre><code>bool result = true; strm = FileUpload1.PostedFile.InputStream; reader2 = new System.IO.StreamReader(strm); // **** new **** FileInfo fileinfo = new FileInfo(FileUpload1.PostedFile.FileName); string savePath = "c:\\"; // example "c:\\temp\\uploads\\"; could be any path string fileName = fileinfo.Name; string strFilePath = savePath.ToString(); savePath += fileName; FileUpload1.SaveAs(savePath); string strSql = "SELECT * FROM [" + fileinfo.Name + "]"; string strCSVConnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + strFilePath + ";" + "Extended Properties='text;HDR=NO;'"; // load the data from CSV to DataTable OleDbDataAdapter oleda = new OleDbDataAdapter(strSql, strCSVConnString); DataTable dtbCSV = new DataTable(); oleda.Fill(dtbCSV); if (dtbCSV.Columns.Count != 2) { result = false; } </code></pre> <p>because I want to count the number of columns in the file, I'm using the oledb reader. which needs a file to be queried.</p> <p>Is it possible to Query a stream? I dont want to save the file, instead just read it without saving.</p>

    1. CONope you can't query a Streamreader's data..You'll have to somehow save the file first...

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.
