View 2 RepliesI am working on a comparison tool that will take an excel file and a .csv file and find differences. The user is going to be selecting the two files from their local machine via the .NET FileUpload control. The issue I am running into is that I don't want to write the files to the server first so using something like below won't work for me, as "Book1.xls" or even " + FilePath + " in place of it won't work. I need to be able to read the posted files into memory, then create maybe datatables of them, then do my comparison code.

I have some code that reads the PostedFile into a stream but I don't know how I can use that stream with the above code. Then I have some that can read the .csv file, but if it is an excel file, I get a bunch of Excel garbage along with the data...

How can I read into clean data from a FileUpload control of an Excel document?
i had 2 columns in the excel file one is SNo and another Description
looks like below
Sno Description
1 1/2 Feet
2 1/5 Feet
3 20
4 30
i read the data from this file using below code
string strFileName = FileUpload1.PostedFile.FileName;
string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFileName + ";" + "Extended Properties=Excel 8.0;";
OleDbConnection objConn = new OleDbConnection(connectionString);
objConn.Open();
String strConString = "SELECT * FROM [Product Classification 5$]";
//where date = CDate('" + DateTime.Today.ToShortDateString() + "')";
OleDbCommand objCmdSelect = new OleDbCommand(strConString, objConn);
// Create new OleDbDataAdapter that is used to build a DataSet
// based on the preceding SQL SELECT statement.
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
// Pass the Select command to the adapter.
objAdapter1.SelectCommand = objCmdSelect;
// Create new DataSet to hold information from the worksheet.
DataSet objDataset1 = new DataSet();
objAdapter1.Fill(objDataset1, "ExcelData");
but in it doesnt read the Description data of 20 & 30 because somebody said if the first cell value is string type then all the column should be string but in mycase its coming as mixed(alpha & numeric), so that it cant read the data, i tried to convert the column as Text then also the same problem continues,

I've got a macro that updates a copyright header with the most recent edit date.
The problem I have is that the macro currently reads through the entire file rather than just the first 6 lines (which is all it needs).
Is there a way to get the Macro to only read the first "X" lines rather than the entire file?
