Web Forms :: Opening A Protected PDF With Page.Response?
Apr 6, 2010
I am trying to open a PDF file that is protected. Is there a way using Response.AddHeader to define the password without having to prompt the user? Adobe automatically prompts the user to enter in the password. I do not want this to occur.
The following is how the pdf file is served to the user:
[Code]....
The file is protected as it may contain private information and we do not want to the user to freely download the file using Adobe reader without having the pdf protected. Is there a way to pass the password to the browser without prompting the user (through Adobe)?
In ASP.NET, if a file was downloaded on a page that was protected by SSL, through a server-side postback that writes to HttpContext.Current.Response.OutputStream, is the transmission that file ALSO protected by SSL?
i am posting some data from my application to an external website i.e for a credit card payment
so i am using a response.write object.how to display the reposnse.write in a new window
this is my code
Dim sb As New StringBuilder() sb.AppendFormat("runat=server") sb.Append("<html>") sb.AppendFormat("<body onload='document.forms[""form""].submit()'>") sb.AppendFormat("<form name='form' action='{0}' method='post'>", postbackUrl)
it works fine when i run it in debug mode, but gives the following error when running through IIS Problems during Load Problems came up in the following areas during loadMissing file: QTnicFLJ5JKZN8dyEzUEsK2jPtygbkw....
Usually when we create an aspx page and then open the aspx.cs page we can see a protected void page_load().So my question is why that should be protected in default.Can we give other access modifiers.
I'm using Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.HtmlEncode(FileName)); to pop a 'open/save file' dialog for the users, so that they can download an file on to their local machines.
This is working good normally in IE7,But on IE6 the file is not opening when user click on the open button in 'open/save file' dialog. I gone through the net and found that Response.AddHeader("Content-Disposition", "inline; filename="+Server.HtmlEncode(FileName)); should be provide to work that in IE6,and its works fine..
But the issue is most of the files that can open in browser opens on the page itself.. ie user on a mail page and click download an image file it opens there,, i need it to open in another window as in case of IE7 what can i do... other files that cannot open in bowser open with current application in system ie(word,excel etc)..
The Code i used is here....
Response.AddHeader("Content-Disposition", "attachment; filename=" +FileName); Response.AddHeader("Content-Length", file.Length.ToString()); Response.ContentType = ReturnExtension(file.Extension.ToLower()); Response.TransmitFile(file.FullName); Response.End(); private string ReturnExtension(string fileExtension) { switch (fileExtension) { case ".txt": return "text/plain"; case ".doc": return "application/ms-word"; case ".xls": return "application/vnd.ms-excel"; case ".gif": return "image/gif"; case ".jpg": case "jpeg": return "image/jpeg"; case ".bmp": return "image/bmp"; case ".wav": return "audio/wav"; case ".ppt": return "application/mspowerpoint"; case ".dwg": return "image/vnd.dwg"; default: return "application/octet-stream"; } }
I have code examples from some of my previous work that help me to post form values to a web page (login credentials) and retrieve the text from that page. Now I want to pass in form values (login credentials again) but actually open that web page in a browser given those credentials.How do I do that? I'm not doing anything nefarious. In our CRM app (home-grown as it is), I want to create a link button that opens our web site's protected products page given the user's credentials (based on the user's login credentials). Normally, I'd copy the user's credentials in our login page which then takes me to the products page.

I need to open a new window or page keeping the existing page open. I plan to put a Button on the existing page and when a user click the button, a new page or window pops up with what I have coded for that page. My preference would be that the user don't have to tweek any browser options or configure anhing else to open the new window with the click.
Now my problem is when ever the pop-up window opens, the parent page loses its focus and goes to top of the page(I guess this is beacuse the page is posting back when the button is clicked).But I could set the foucs again when I am closing the pop-up window by using
I am using asp.net to call the reporting services report. In my asp.net page, there is a parameter screen which while running opns the reporting services report in asp.net page as pageA.aspx Now, whenever, I again change the parameters on the parameter page and click the run button, if pageA.aspx is already opened, it just refreshes that page but the page doesn't generate new results ( caused by the change in parameters). I want to close that page (pageA.aspx) before generating the same page with other values (caused by the change in parameters in parameter page). I want this function in page_load() function of the param page.
Searched and couldn't find anything. I'm wrtiting an intranet application, and it creates links to see the original PO or Order for a given order number. Problem is that some of these orders were never put into the system electronically, so you get an error 400, no such page. Is there some way to programatically 'test' a link before sending the user to this error message?
any page that I open in my browser comes up blank.
I don't get any errors, it just comes up blank.
I also noticed that it seems to bypass forms authentication. For example, even though the page I open is blank, it is the actual page name that shows up in the browzer instead of the page that it usually redirects to for the forms authentication.
I have designed menu using <ul> and <li> tags and handled onserverclick event, where redirection code is written. This code works fine for normal click. But when I right click on the link and select "Open link in new tab", it opens blank page. So how can I handle this scenario.
I started a new web project in VS2008 coding in vb.net. When I double-click on a control in the designer screen to go to the vb code page so I can code on some events, the control does not show in the control dropdown which means I cannot get to all of the different events. The only way I can do this is to add a line like below inside the class at the top:

I am working with another project that does not have this problem. Is there a setting that changes this?
I need to hide the menu and tool bars of a browser window, and the only examples I've found on how to do this are in the DOM with a javascript window.open command similar to the following:
The problem is, I cannot use this as the page (an aspx form) is being called with a server.transfer, so there really isn't a way to use the above code. Is there a way to set the toolbar and menubar without using window.open?
I have a web page in that contains an infragistics grid control. In this is a column that when double-clicked on, a new window needs to popup that allows a user to enter "Comments". It's basically an .aspx page. I just need it to pop up over the current page. How can I do this in the VB code-behind?
I have a site in which I have defined my Start up page, say Sample.aspx. After deployment in server named "Siteserver, Now whenever I open link [URL]. Now, my question is, if I have more than one page like Sample1.aspx and Sample2.aspx and I want to open [URL] directly, how can I do this. It is redirecting again to Sample.aspx. How can I achieve this.
