I have a page that generates an expense report based on user input. I get the file to generate correctly and saved on the network, but I also provide an option that after the file is created that it is allowed to be saved locally (downloaded). The Excel file is generated using the Aspose library:
expenseReport.Worksheets.RemoveAt("Sheet1")
Dim TempExpenseFile As String = Server.MapPath("~/Temporary Files/") & "Expense Report - " & FirstName & " " & LastName & ".xls" 'Generate a temporary file name
expenseReport.Save(TempExpenseFile, FileFormatType.Excel2003) 'This saves the actual file
Dim file As FileInfo = New FileInfo(TempExpenseFile)
The following code is what I've been trying to work with, to allow the file to download, based on user posts and tutorials:
Try
Response.ContentType = "application/vnd.ms-excel"
Response.AppendHeader("Content-Disposition", "attachment; filename=" & file.Name)
Response.WriteFile(TempExpenseFile)
Response.End()
Catch ex As Exception
MsgBox(ex.Message)
End Try
However an exception is always thrown. The message is "Thread was being aborted." From what I read this is caused by Response.End and it is safe to ignore. So I've tried the above code without the Try-Catch block and I've also tried changing Response.WriteFile to Response.TransmitFile however the file is never downloaded. What am I missing here? Thanks in advance for any help.

from MSDN: "When this method is used with large files, calling the method might throw an exception. " (http://support.microsoft.com/kb/812406)
Possible?
Also, maybe, try this before the .ContentType: (C# version...I don't know the VB equivalent syntax)
Response.ClearContent();
Response.ClearHeaders();

When he logs in, check if he has a license, if not, redirect him to a page where he can get one...

Hi,
I have parent.aspx page which has a grid, the grid has column named Date.
When I double click on that column, the child.aspx page will pop-up.
The pop-up page is a MODAL DIALOG which is the "showModalDialog("child.aspx")".
Now, on that child.aspx dialog page,it has a calendar. If I will change the
date then click update button. The parent.aspx page should automatically refresh
without closing the child.aspx page, but it does not.
There is an example here in codeproject which is exactly the same on my problem
but it uses window.open not dialog. Behavior of window.open and dialog is not the
same. You cannot call the window.opener.document.forms(0).submit(), it will
generate error.
Please help.
Thanks.

In order to do that as you said you can use the opener method;
You can change the href of the parent page by => window.opener.location.href = {URL};
If that doesnt work you can try reloading the page. You can reload the page in two different ways.
This will return the form to its default values though => window.opener.location.reload(true);
If you want to preserve form data , use the history method.
window.opener.history.go(0);

first of all, you need to use pre tags around your code. That will make it
look like this and be far more readable to the people who might be willing to help.

Here is the correct way to write question:
I am using Jquery calander control in my project. When i click any button the value in the textbox is cleared. Kindly help me to resolve this issue. I have to take the textbox value and save it in DB.
<script type="text/javascript>
$(function() {
var pickerOpts = {
showOn: "button",
buttonImage: 'calendar.gif',
buttonImageOnly: true,
changeMonth: true,
changeYear: true,
showButtonPanel: true,
dateFormat: 'dd-M-yy'
};
$("#datepicker").datepicker(pickerOpts);
$.datepicker.setDefaults($.datepicker.regional['']);
$("#datepicker").datepicker($.datepicker.regional['en']);
$("#datepicker").val();
});
</script>
<form id="form1" runat="server">
<asp:Label ID="lblDate" runat="server" Text="Date: ">

Dear all,
I have a solution with multiple class library and Asp.net projects.
I want to have a common configuration file for common configuration/settings for all those projects in my solution.
What is the best way to achieve this ? (i didn't find a good solution on the web yet  ).
Thanks in advance.

Do you mean a common web.config for the ASP.NET projects, a common config file for the class libraries, or both?
If you are using source control, such as TFS, a single file could be included in multiple projects. On the file system you could also link the files to each project rather than each having their own.

Hi Mark,
I mean a common config file for both, Asp.net and class libraries. It is one application with different modules.

Doesn't everyone?
Please don't ask people to do your work for you, it's irritating for us and it won't help you. Do some Googling, ask for resources and work your way throught it.
If things get tough and you have a SPECIFIC problem you would like help with, ask the question here. I highly doubt anyone here will help you build something from scratch.
Start here[^]. When you get stuck on something specific, come back and ask for help.

What you're looking for is HttpWebRequest and HttpWebResponse. These can be used to talk to websites using HTTP and download their content just the same way your browser does.
Here's an article right here on CodeProject[^]. Also some MSDN reference material here [^]and here[^].
Basically you will take the URL, send a HTTP GET request, the server will return the HTML of the webpage. You will need some string processing (generally called "HTML scraping" if you want to Google) to get the content you're after. Then any image locations you find in your HTML scraping, you will need to get their URLs and send HTTP GET requests for each to download the image data.
Make sense? So, keywords for Google:
HttpWebRequest
HttpWebResponse
HTML Scraping

Can we assign same domain name to multiple websites on same web server?
|
|
|
|
|
I am not sure what you are trying to achieve.
Even if you do so, say some how, which website you want to return when user will navigate to that website?
I could think of the following scenario you could do:
1. You can create different sub domains and assign each sub domains to each website.
2. You can also write your own ISAPI extension to redirect to different websites based on your need/logic on the same web server.
3. Easiest of all, assign domain to a default website, create a custom http handler, server.transfer to other site based on the your business logic.
Hope this will help.
