I want to show a PDF in browser, from which user can select text, showing pdf is very easy i have done this using "pdfviewer" control, now i want to get the selected text which the user selects in the PDF, is there any way to achieve this? i am using asp.net
View 2 RepliesIn an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is:
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.AddHeader("Content-Disposition", "attachment;filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.End();
This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this:
HttpResponse response = HttpContext.Current.Response;
response.ClearHeaders();
// Setting cache to NoCache was recommended, but doing so results in a security
// warning in IE6
//response.Cache.SetCacheability(HttpCacheability.NoCache);
response.AppendHeader("Content-Disposition", "attachment; filename="theFilename.pdf"");
response.ContentType = "application/pdf";
response.BinaryWrite(MethodThatReturnsFileContents());
response.Flush();
response.End();
However, I don't believe that any of the changes made will fix the issue.
I dont know whether this simple task or not, but I tried to search in google but couldn't find anything.
I've a asp.net form and user enters some data in the text boxes provided. Whenever user submits the form, browser will save that form data. I don't want this form data to be saved in browser. How can I restrict the browser saving this form data without touching the browser settings?
Application is developed using asp.net and normal text boxes are used here.

I have placed the code below on a page. The strange thing is that the "SOME TEXT" string doesnt show up in the page! I do see "upanel" and "pnl":
upanel
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
pnl
<cc1:TabContainer OnActiveTabChanged="TabChanged" ID="tabContainer" runat="server"
ActiveTabIndex="0" OnClientActiveTabChanged="ActiveTabChanged" Width="100%">
<cc1:TabPanel ID="tp1" runat="server" HeaderText="A tab">
<ContentTemplate>
<asp:UpdatePanel ID="UpdatePanel3" runat="server" UpdateMode="Always">
<ContentTemplate>
SOME TEXT
</ContentTemplate>
</asp:UpdatePanel>
</ContentTemplate>
</cc1:TabPanel>
</cc1:TabContainer>
</ContentTemplate>
</asp:UpdatePanel>
HOWEVER, when I view the pagesource, I see this, so the text IS rendered to the browser! What can be happening here?
upanel
<div id="ctl00_CPHCenter_UpdatePanel2">
pnl
<div id="ctl00_CPHCenter_tabContainer" style="width:100%;visibility:hidden;">
<div id="ctl00_CPHCenter_tabContainer_header">

Whenever there is a configuration error inside the web.config, the server sends a yellow screen of death to the browser with a few lines around it. My problem is I am using impersonation and I don't want the users to see the impersonating username/password. So how can I prevent the server from showing the web.config code??
View 1 RepliesI am using a Webgrid as part of an MVC 3 app. The weird thing is the first display of the page with the grid displays fine but when I click on a heading to sort, the grid is not displayed as part of the page when I am running under the web server provided by the VS 2010 installation. When I do a View Source of that page, all of the grid stuff (as table elements) is there to be displayed. It just does not show up in the browser. So, I wrote the html to a file and copied the javascript and css files to the same folder and then ran the file under IE and everything displays as it should.
View 1 RepliesI've a view which display all data. I'm using ViewData, for loop etc.. on the view, to show the data. It may sound weird, but is it possible to write view to disk as a file instead of showing in the browser. The reason is that, business wants functionality to send the same view file as email attachment to the user.

The days list shows fine but the selected value is not 2 but "---". Why?
I have a .net 3.5 web form with an ajax combo box and a text box inside it. The bombo box is bound to a SqlDataSource.
My requirement is to show/hide the text box depending on the text of the selected item in the combo box. If a particular string, say 'xyz', appears in the text of the selected item, the I will make the text box invisible. I enabled the AutoPostback, made the text box disappear in the SelectedIndexChanged event, and everything worked fine.
However, when users enter their own texts (which are not in the list items), I am unable to show / hide the text box. I've tried the TextChanged event but nothing happens. It seems the event is not trigger after I enter a new text and locate the focus to other place.
is there a way to prevent the user ented text from being inserted into the bombo box?

View 13 RepliesWhen you click Questions, Tags, Users etc. at the top of stackoverflow, the one you're looking at becomes highlighted orange. This is (usually) done by changing the css of one of them to be 'selected'.
If you have a single template that all your pages are built with, and that template includes these buttons across the top, how do you highlight one of them depending on which page you are viewing?The problem is that you'd have one template, not one for each page.(If it matters, I am using ASP.NET MVC 2 and setting up a Master page)

I'm trying to set up the SSL in my web app, but don't know if i'm doing it right, or if even i'm taking the right steps in the right order.I have a function in a class that returns the secure URL (https://mydomain.com/...aspx) if the current url is not secure (http)
[Code]....
(Though in develop environment It's like "https://localhost:port" + rawUrl)
when the function returns ssl value, if it's not empty, then the master page redirects to the new url... but the browser is not showing it...
URL.... Still there will be need of url in ajax method if i put javascript in site.master.cs . As what i have understood from that mysite.master.cs will be like this :
protected void Page_Load(object sender, EventArgs e) {
try {
if (Session["Prefix"].ToString().Trim() == "sys_admin") {
UserNameMasterLabel.Text = Session["UserName"].ToString().Trim() + " (ADMIN)";
[code]....
And site.master will be like this :

SessionStateSection section = (SessionStateSection)config.GetSection("system.web/sessionState");
int timeout = (int)section.Timeout.TotalMinutes * 1000 * 60;
return timeout;
}
But I have several pages in my website , by doing the above story will it work for Builder.aspx ? or any other page rather than dailylog.aspx ?
List controls deriving from ListControl, such as DropDownList, ListBox or RadioButtonList, are populated by a list of ListItems. A ListItem has a Value and a Text property.
ListControl offers the following methods to access the currently selected item:
ListControl.SelectedItem returns the currently selected ListItem,
ListControl.SelectedValue returns the Value property of the currently selected ListItem.
Now, the interesting thing is:
ListControl.Text returns exactly the same value as ListControl.SelectedValue. It does not return SelectedItem.Text, as one might expect.
This is by design:
[code]....
The Text property gets and sets the same value that the SelectedValue property does.
This seems counter-intuitive and confuses people. My question is: Why was it done this way? I can imagine that providing a Text property is necessary for implementing the ITextControl interface, but why on earth would you choose to have it return the Value of the ListItem rather than the Text?
In the IIS, it shows that the web app (i'm using) is using an application pool that uses NETWORK SERVICE account for identity. But when I debug/run my web app, User.Identity.Name shows that my windows user login instead. I checked my web.config file, and it does not have Impersonate enabled. In fact, I set it to false, and it still shows the same.

I have written a SP which maintains users log in and log out history,it works fine when any user logs in or clicks on log out, problem is that as per need its not to allowed to keep the screen idle for 1 minute or more then in the log out column Null value is passed.
SP
Create proc usp_trackuserlogindetails
@username varchar(50) = null,
@command int = 0
as
BEGIN
if(@command = 0)
begin
insert into userlog (USERNAME,LOGIN,LOGOUT) values (@username,Getdate(),Null)
[Code] ....
Here when user manually clicks the log out button then 1(table above) is the output.
When user leaves the screen idle then after 1 minute the page goes to the Login.aspx page if the user tries to do something on the current page,here 2(table above) is the output can i store some hard core value instead of Null like Session expire or the exact session expires time.
