This code is collected from "http://forums.asp.net/t/956392.aspx"
Export to Excel in ASP.NET is a very common feature, which I'm sure everyone who has worked in ASP.NET would have had the chance to implement.
Whenever we choose the Export to Excel option from our Application, a dialog box pops us with the option to Open or to Save.
By chance if the user checks off the option "Always ask before opening this type of file" that is shown in the dialog box, from next time the user will not be able to see the dialog box. Instead, the excel file opens up in the same window.
To set back this option, the following steps can be followed:
1. Go to Windows Explorer.
2. On the Tools menu, click Folder Options, and then click on the File Types tab.
3. From the Registered file types list box, select the XLS extension, and then click Advanced.
4. In the Edit File Type dialog box, set the Confirm open after download to selected.
5. Make sure the Browse in same window option is not selected, and then click OK.
The above steps will make sure that we get the dialog box as shown above. However, since this is an option set at the client computer, these steps cannot be mandated to be followed in every computer that browses the application.
So, from the code level, we must make sure that the excel file is opened in a separate window. One possible option for this is to Save the file to the web server, and then open the file in a separate window.
The code for this is given below:
private void ExportToExcel(DataGrid dgExport)
{
try
{
string strFileName = String.Empty, strFilePath= String.Empty;
strFilePath = Server.MapPath(@"../Excel/") + "ExcelFileName" + ".xls";
if (File.Exists(strFilePath))
{
File.Delete(strFilePath);
}
System.IO.StringWriter oStringWriter =new StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new HtmlTextWriter(oStringWriter);
StreamWriter objStreamWriter;
string strStyle =@" .text { mso-number-format:\@; }
";
objStreamWriter = File.AppendText(strFilePath);
dgExport.RenderControl(oHtmlTextWriter);
objStreamWriter.WriteLine(strStyle);
objStreamWriter.WriteLine(oStringWriter.ToString());
objStreamWriter.Close();
string strScript = "window.open('../Excel/" + "ExcelFileName" +
".xls','dn','width=1,height=1,toolbar=no,top=300,left=400,right=1,
scrollbars=no,locaton=1,resizable=1');";
if(!Page.IsStartupScriptRegistered("clientScript"))
{
Page.RegisterStartupScript("clientScript", strScript);
}
}
catch(Exception)
{
//Handle Exception
}
}
In the above method, the file is saved to the Web Server inside the folder "Excel". Of course, this folder must have write permissions for the user. But it will definitely ensure that the excel file is opened in a new window in the client computer.
**** I think it helps U ****

Try This:
#Region "Export To Excel Button Click Event"
Protected Sub cmdExportToExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdExportToExcel.Click
Dim sw As StringWriter = New StringWriter()
Dim htw As HtmlTextWriter = New HtmlTextWriter(sw)
Try
Dim ml_strFileName As String = ml_strSaveFileName
Dim attachment As String = "attachment; filename=" & ml_strFileName & ".xls"
Response.ClearContent()
Response.AddHeader("content-disposition", attachment)
Response.ContentType = "application/ms-excel"
Gridview1.RenderControl(htw)
Response.Write(sw.ToString())
Response.End()
Catch ex As Exception
Finally
If Not sw Is Nothing Then
If Not htw Is Nothing Then
sw = Nothing
htw = Nothing
End If
End If
End Try
End Sub
#End Region
#Region "VerifyRenderingInServerForm"
Public Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
End Sub
#End Region
Hope this helps u???

Hi there,
Some third party products can do that. Check out a tool called StateMirror.

But it still not Ok !

I am prettysure it would need to go before the waitforexit, but you might need to pause for a second before you write it. So maybe something this would work:
MyProc.Start();
Threading.Thread.Sleep(1000);
StreamWriter myStreamWriter = MyProc.StandardInput;
myStreamWriter.WriteLine("my password");
myStreamWriter.Close();
MyProc.WaitForExit();
Hope that helps.

Hi
Do you want to add text boxes at runtime?
If yes
dim MyTxtBox as new TextBox
set watever properties you want using "MyTextBox."
Add MyTextBox to panel,placeholder or to ASP Tables or any other.
eg:
panel1.controls.add(MyTextBox)
To succeed, we must first believe that we can.

If you have a form you call a splash screen, how are you closing it ?

I am just learning asp.net and I am doing some work for my company who has several asp.net sites already built. The particular site I am having trouble with has some codebehind files it is using. My problem is that I cannot find the aspx.vb files it is referring to. I realize that dll files are created and the site is actually using those files, but I want to look at the code it is using. Where are these files usually kept?
Thanks for the help.

The files will be contained in the solution which created the DLL - if you don't have access to them - download REFLECTOR and open the DLL files with that - you can at least see what the code behind looks like even if you don't have access to the original files.

They in the project that was used to create the website. Usually they are stored in some version control system, such Visual SouceSafe, or could possibly be on the developers machine (very bad practice). Ask the person(s) who created the site.
