Intresting. 
make EnableViewStateMac = false and try your luck
I think the root casue might be client using Vista and IE8 or IE7
are you not tracking client browser in error log. try to do that
that helps in trouble shooting.
If you have not checked this . go through it.

I have a website up on a server & while I'm still debugging, I have the website's images stored on a separate server.
Unfortunately though, it appears I don't have the propper permissions set on my image server because everytime I try to view my website, I'm being prompted with a windows login popup (you can see an image of the popup here http://97.74.54.51/login.jpg[^] )
Any idea what permissions I need to set to remove this password?
Thanks.

You must have made a Virtual Directory for the images on the server.Provide it Anonymous access.
Cheers!!

hi,
i am opening a web application from a windows applicatino using
SHDocVw.InternetExplorer.
eg.
object vPost, vHeader, vFlags, vTargetFrame, vUrl;
string vPostData;
vPostData = "SecKey=123&Uname=xyz";
SHDocVw.InternetExplorer ie; //Class ie = new SHDocVw.InternetExplorerClass();
vFlags = null;
vTargetFrame = null;
vUrl = "http://localhost/app/StartUpPage.aspx";
vHeader = "Content-Type: application/x-www-form-urlencoded" + Convert.ToChar(10) + Convert.ToChar(13);
//Convert the string to post to an array of bytes.
vPost = ASCIIEncoding.ASCII.GetBytes(vPostData);
ie.Navigate2(ref vUrl, ref vFlags, ref vTargetFrame, ref vPost, ref vHeader);
In the above code vpost is an bytes array which i am posting to the web application.
my question is how to receive the posted data in a web application

I have a user control on my site (in directory UserControls/UserInfo. When I drop the control onto a page created from my master page template, it does nothing (i.e. you click on the "login" link and nothing happens). I even added an explicit link to a Login.aspx url on the LoginStatus line, which will work. However, the LogOut link does not work.
I've found I can drop this user control onto any new, blank (i.e. not derived from MasterPage.master) and all works as expected.
Also, when I run in debug mode, I get the following error when I click on the Login link:
"Microsoft JScript runtime error: Object doesn't support this property or method"
The method highlighted is: "theForm.submit();"
This call is in the javascript function created to do the postback:
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}
The javascript issues I just listed may be a red herring.
I've included the user control code below. Any assistance on why this doesn't work within master pages would be helpful and greatly appreciated.
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="UserInfo.ascx.cs" Inherits="UserControls_UserInfo" %>
<asp:loginview id="LoginView1" runat="server">
<anonymoustemplate>
<rolegroups>
<asp:rolegroup roles="Administrators">
<contenttemplate>
<asp:loginstatus id="LoginStatus2" logoutaction="Redirect" runat="server">
ReelPushMowers

<asp:loginstatus id="LoginStatus1" runat="server">

formatstring="Hello, <b>{0}</b>!">

...make sure that you don't have any other form controls on your page that have ID="submit". This caused the same error on my system whilst converting an HTML layout to ASP.NET because JavaScript was referencing a form element called submit, rather than the submit() method of the form.

To is a read only property. You need to pass the to address via constructor when you instantiate MailMessage class. See documentation[^].
jojoba2010 wrote: txtContactUs.txt;
txt is not a valid property. Try txtContactUs.Text.
These are very basic stuff and I suggest you to get a good book on the subject and start reading it.
Best wishes,

If I remember correctly, I have posted you the code few days back. See I have wrote this code in CP's editor itself, that why some mistake is there. But from the error it is quite understandable.
Please do as navaneeth suggested.

You can't unless quick books provide some API to access their data.

Try This one,
Use this code in your Code Behind
Page.ClientScript.RegisterStartupScriptthis.GetType(), "JSFunc", "MyFunc();", true);
This is your JavaScript Code :
<script type="text/javascript">
function MyFunc()
{
alert('JS Calling From Code Behind');
}
</script>
Hope this will help you
