Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Me.IsPostBack Then Dim dataSet1 As New DataSet dataSet1 Dim dataSet2 As New DataSet dataSet2 Dim dataSet3 As New DataSet dataSet3
Dim dataSets As New List(Of DataSet)() dataSets.Add(dataSet1) dataSets.Add(dataSet2) dataSets.Add(dataSet3) Dim strout As String = Server.MapPath("test1.xls") DataSetsToExcel(dataSets, strout) End If End Sub
How to create each excel sheet non-editable (read only)
I used this coding for export to excel, by using this coding i got only 65,536 rows only. How to bind more than 65,536 records or how to move the balace records to sheet 2 by using this method.
Protected Sub btnExportExcel_Click(ByVal sender As Object, ByVal e As EventArgs) Dim ars_stock As New DataTable ars_stock = cls.FillDataTable("select top 70000 * from spal..po_acc_details") Response.Clear() Response.Buffer = True
I have code to export the grid to excel . i have taken it from [URL] now i want to save excel file directly without asking user to save it or open it at client side. i want to save it on server folder. how to do that .
I have some code that reads records from an excel file and then imports that data into an sql database. The issue only happens when the excel file has more then 350 rows in it. In the middle of the import it just stops executing and I get directed to the 'Internet Explorer cannot display the webpage' page or just a blank page when using firefox.
I dont get any time out errors or any error at all but still I tried messing around with the script timeout settings but still does the same thing at about the 2 min 30 sec mark.
I understand how to use a connection string object to read excel sheets. What I don't know is how to follow a hyperlink inside excel, grab matching data from the linked page and return it to my database. Essentially, the spreadsheet has two columns:
Title | Class#
Class# has the hyperlink which links to an internal web site. The connected page has a course description and any pre-required classes that must be taken before you can take this class. This is where I'm rather stumped as I've not had to do this type of thing before.
