I have an issue with excel downloading with one of my aspx page. Excel file size is 256KB only. File downloading from all aspx pages except from one aspx page. I am not understanding why this is happening. Not only that, It is working on DEV and QA environments but when we pushed the same code to production. it is not working.
[Code]....
In my web app, I have an aspx page which contains an html table and several lines of text. I need users to be able to download this whole page as a separate file.
In the past I have used the a webclient to do this:
Dim myWebClient As New System.Net.WebClient
myWebClient.DownloadFile(strSource, strDest)
Response.AddHeader("Content-Disposition", "attachment;filename=test.doc")
Response.Write("test.doc")
but it appears this is only able to download html pages.
I have been trying to download the file from a virtual directory ( which is pointing to some other location) within the web-folder. I have implemented 2/3 ways on doing that, but none of the ways download the file. The asp .net page is not even showing the error, its showing a blank screen. One of the pice of code I implemented is:
<code>
filename = LinkButton2.Text
filepath2 = Server.MapPath("/folders/") & uname & "/" & filename
HttpContext.Current.Response.ContentType = "application/octet-stream"

I use following code to download a web page source code in my project:

The web page I am trying to download is a intranet site. I am periodically downloading the web page for archiving purpose for future reference. The web page will list the current active jobs/projects we work. We process 100's of jobs everyday. The list item will have the Project id, Project name, Project deadline, etc.The download works fine. the web page is downloaded locally. The problem is the date/time format is changed to some other format. If I view the web page in browser, the deadline of one of the project shows as "7/15 03:00".
However, the downloaded webpage shows the deadline of that project as "Wed Jul 14 16:30:00 CDT 2010". I believe it shows in CDT timezone. Also, it shows couple of other timezone too. I think the project might be created from those countries. I am in India timezone.
I am downloading page data using the stream reader using readline.I want to concatenate each line into one long string for parsing The below line of code is not working: datajoined =dataline.Insert(datajoined.Length - 1, dataline.Length - 1)My inevitable goal here is to track stream data with a progress bar. But first I must learn to dload page data in chunks.

View 2 RepliesI'm downloading a page and stripping out the HTML. I actually stripped out everything successfully, but there is something weird with the "<br />" tag..
When I try to replace <br />, I can't detect it..
Unlike other HTML tags such as <br> and such, <br /> does not show up as a text in my TextBox.. it shows up as a BOX and messes up the whole formatting.Does anybody know how I can go about removing the boxes from my textbox?

In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < b>Column Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

I am writing a report to an excel template and am trying to insert a page break into the report. Part of my code is included:
Imports msWE = Microsoft.Office.Interop
Dim Rnge As msWE.Excel.Range = excelApp.Range("A20:M20")
Dim excelApp As New msWE.Excel.ApplicationClass
excelApp.Worksheets.HPageBreaks.Add(Rnge)
Now the pagebreak code executes but it does nothing. Its almost as if it is being ignored. Also I have heard that using Microsoft.Office.Interop is not a good idea as it is slow and unstable.
Basically, i have to write a small application that just writes in certain cells of a set page of an excel sheet, the sheet will always be the same layout.

View 3 RepliesI have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

View 1 RepliesThe thing is i have a Master page and a Content Page. I have a LoadComplete in Content Page and a PreRender in Master Page.

For some reason all controls on the aspx side go through the Master Page prerender except the ones that i change on the LoadComplete side. How can i make sure the entire content page loads and then the Master Page PreRender event is called, making all the controls go through that event.

The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.
