securing webapp with web.config

3-Aug-06 2:15

Shell32 is running on your server, not in the browser. Are you wanting to allow users to upload a file via a web application? The only thing you can do is use the html file input control.

how vital enterprise application are for proactive organizations leveraging collective synergy to think outside the box and formulate their key objectives into a win-win game plan with a quality-driven approach that focuses on empowering key players to drive-up their core competencies and increase expectations with an all-around initiative to drive up the bottom-line. But of course, that's all a "high level" overview of things

Hi all,

I'm trying to set up my web app so that it doesn't display error/debugging/tracing messages to visitors.

I have already tried the following but i still get the Description:, Exception Details:, Parameter name:, Source Error: etc that you get from the debugger

My Web.Config has:
<trace enabled="false" pageoutput="false"> <compilation debug="false" explicit="false">

No pages have the debug set to true.

IIS has clientside debugging disabled.

Any ideas on how i can sort this out?

Thanks in advance.

hi Orb1t,

If you try below code in to web.config file and check that

<trace enabled="true" requestlimit="20" pageoutput="false"
="" tracemode="SortByTime" localonly="false">It is working but incase it is not work then try to flase tracing at page level like below:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="Trace.aspx.vb"
Inherits="MCSDWebAppsVB.Trace" trace="True" %>

Chetan, Thanks for your reply + suggestions. I've tried both of them but had no luck with it, the server still returns the parser errors.

Any other ideas?

Cheers

I think what you are trying to do is set up custom errors. Turn the <customerros mode="On" defaultredirect="YouErrorPage.aspx">

Thanks ToddHileHoffer, this is exactly what i want to do. Big Grin | :-D

I just wondered whether there might be a way in which i could get it to use IIS' defualt script message'An error occurred on the server when processing the URL. Please contact the system administrator.' and avoid having to create customs + have the 302 redirects.

Error while providing file download in webpage

I have to provide download of files in ASP.NET 2.0
I am using following lines of code.

try
{
Byte [] bytes = this.ContentController.GetFileContents(filePath);
Response.Clear();
Response.AddHeader("Content-Disposition", "attachment; filename=File" + _fileExtension);
Response.AddHeader("Content-Length", bytes.Length.ToString());
Response.ContentType = "application/octet-stream";
Response.Buffer = true;
Response.BinaryWrite(bytes);
Response.Flush();
}
catch(FileNotFoundException fnfe)
{
this.ShowErrorMessage(this.GetErrorString(ResourceIdentifiers.DOCUMENT_FILE_NOT_FOUND_ERROR));
}
catch(Exception ex)
{
this.ShowErrorMessage(this.GetErrorString(ResourceIdentifiers.DOCUMENT_UNEXPECTED_ERROR));
}

Using above code, when one clicks on file link, a default download box of IE appears. If user clicks on Save, the file gets saved on disk and user can open that file. If user clicks on Open, it opens registered application with file type and says, file not found. Using same code I am able to open Word file but I cannot open Excel, PDF files.

Note: My application used Master pages, UIP Application Blocks. The code written above is inside a user control which gets loaded on view (webform) dynamically based on configration(xml) file.

Please can anyone suggest what could be going wrong in the piece of code because of which I am not able to open Excel/PDF files.

Apprciate your help.

Thanks and regards,
Ashish

Seems I get the problem when I use UIPAB. Otherwise the same code works fine.

Any idea what UIPAB does different.

Hi,

I want to make http request for html page of other site in .aspx page of my site. This html page contain frames. I am using webrequest object to request this html page. When I checked the output string of Request.GetResponse.GetResponseStream it contain the html code of the page i.e etc. and not the actual output. Due to this, .aspx page display complete blank output. The code written to call this frame page is as follows.

Request = WebRequest.Create(URL)
'Request.Timeout = 10000
'Request.ContentLength = body.lenth
Request.ContentType = "application/x-www-form-urlencoded"
Request.Method = "POST"
'Request.AllowAutoRedirect = True

ItemStream = Request.GetResponse.GetResponseStream
Dim tr As StreamReader = New StreamReader(ItemStream)
_Result = tr.ReadToEnd

Note : URL is the html page which contain frame and reside on some other server.

Kindly let me know how to request frame page using webrequest object or any other method.

Regards
Nilesh

If you want the contents of the frames, you have to parse the page that you got to get the URL:s for the frames, so that you can request them from the server.

How to compute end date given the start date?

A project in .NET 2.0 C#. I have used the calendar to let user select the start date. However I do not know how to calculate the end date if the duration is 3 months after clicking the submit button. The end date will be displayed at the lblEndDate.

<br />
public DateTime strEnd;    <br />
protected void Calendar1_SelectionChanged(object sender, EventArgs e)<br />
    {<br />
        txtStartDate.Text = Calendar1.SelectedDate.ToString("dd MMM yyyy");<br />
    }<br />
    protected void btnStart_Click(object sender, EventArgs e)<br />
    {<br />
        //strEnd = txtStartDate.Text.ToString();<br />
        //lblEndDate.Text = strEnd.AddDays(90);        <br />
    }<br />

thanks in advance. Much appreciated.

Inspite of using adddays you can use addmonths which requires no. of monts as a parameter.

Thanks you ring something to me. I still insist on using days. And it can work. Thanks Apurva Kaushal.

lblEndDate.Text = Calendar1.SelectedDate.AddDays(81).ToString("dd MMM yyyy"); // subtract 3 days because I want to end on a friday

if you requirement is not fixed to the number of months(an integer) then your choice is obvious of AddDays. Smile | :)
