1) Verify whether UpRSPictureedt has a RUNAT=server attribute. Custom manually typed controls normally, we skip and create this error.

2) upload1.PostedFile should be checked for NULL

In visual studio 2005, Add the reference - Microsoft office 10.0 object Library to your project.

Add the following code in button click event

Dim excel As New Excel.Application
Dim wbook As Excel.Workbook
Dim wSheet As Excel.Worksheet

wbook = excel.Workbooks.Add()
wSheet = wbook.ActiveSheet()
Dim strFileName As String = "The location to save the excel file"
wbook.SaveAs(strFileName)
excel.Workbooks.Open(strFileName)
excel.Visible = True

Try it and check whether its working.

Put a UpdatePanel, and drag your drop down control inside to that. You are almost done

Private oProjApp As Microsoft.Office.Interop.MSProject.Application

This object is used for import and export MPP file to/from databse.

Everything is working file.

But If I import (save physical MPP file to database) same file in consecutive manner (more than once) it hang on process on statement

oProjApp.FileSaveAs("<mpp_dsn_1>\" + ProjectPlanName, Microsoft.Office.Interop.MSProject.PjFileFormat.pjMPP, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, "sa", "mpcs", "MSProject.odbc", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing)

To come out of this I need to kill process from command prompt

Kill winproj.exe

Then it works fine again.

Does anyone has any idea regarding same ?

This is one way to send values accross pages

To send string
page.aspx
response.redirect("page2.aspx?ProjPlanName='test'")

To retrive string value
page2.aspx
Request.QueryString("ProjPlanName")

Thanks,

Assume you are posting from page1.aspx to page2.aspx. So page1.aspx code would be

Response.Redirect("Page2.aspx?MyQry=Helloworld");

In page2.aspx

string QuerystringValue = Request.QueryString["MyQry"];

Hope this helps

There are many differences.

1 - .NET2005 introduced partial classes
2 - ASP.NET2005 introduced entirely different folder structure from .NET2003
3 - New events introduced in ASP.NET page life cycle
4 - Master pages introduced on .NET2005

and many more..

AJAX is mot .NET specific. It can be used in any web scripting languages. It's written with javascript, and it works on the client side. Check documentation for using XMLHttp object in javascript to get started

An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.
