Take A Screen Capture Of A Particular Area Of The Screen?
Mar 17, 2010
Is it possible to take a screen capture of a particular area of a web-page from the web-page's own ASP.NET code?
I need to display 6 images that are stacked on top of one another using CSS, and I'd like to offer the user the ability to right-click save-as if possible by stacking the screen capture on top top of the original image stack.
I am still new to Jquery and trying to sell my boss on it.Is there any good examples that show how I can say when the user mouses over an area of the screen( for a certian Item) it would popup the details of that item? am using vs 2010 / mvc 2 and would like to use Json to get the data for the popup. So it does not have to be loaded all at one time.
I have question regarding printer option page which pop up when i click on print button on crystalreportviewer and when i click okay on that pop up page it displays print preview of the report.
Is there any way to skip that pop up window(Printer Option) and just display (PDF)print preview screen instead?
(I am not exporting report to pdf, just want to display printview screen and when the user click on print button it will print out the page)
I have tried following code but i am getting error:
"Object reference not set to an instance of an object."
I just want to know how to capture an image using asp.net server side.
My code runs smoothly and captures the image when I'm running it in localhost, but when if I published or deployed it in our web server then access it tru its url, it doesn't work or i can't capture the image.
I have upgraded web application from VS.2008 to vs 2010. I was using previously ReportViewer 2008 control in a page and replaced with 2010 ReportViewer Control.
I have installed the ReportViewer Redistributable also in my local pc as well as in the server. Also as per the new requirement I have placed the Scriptmanager in the web page where the reportviewer control located.
While running the page, the reportviewer run the report and is not showing the data on the screen. It shows the blank screen. But If I export the data to execl or world it is showing the data. Also the page numbers in the reportviewer showing the total pages available in the navigation bar. I am sure the report is running and bringing the data to the screen but not showing it.
The below is the exact scenario, One form will be there and when user click on "Edit" hyper link other window will open to get more details. In that new window also I have a grid or a table which has other hyperlink which lead to open other window and in that window I will enter few details and save it....
I have created my first MVC application. I am using forms authenticataion. I have created a custom action filter MyAppAuthorizationFilter which inherits from AuthorizeFilter. Inside this filter I'm authenticating the user credentials by checking them against a database table (by overriding OnAuthorize method). If the user is not authenticated, I am redirecting the users to a login page (which is view of LoginController). I am using this filter agaginst my main controller so that all actions in this filter will execute only if the user is authenticated.
I do not have any problem when I use the asp.net development server (shipped with Visual Studio). But when I deploy the app to our IIS7 server, I can see the login screen when I access the default url, but after entering the credentials (both correct and incorrect) and posting back the Login page, it stays on the Login page (clears the pwd, but not the username). Its never getting redirected to the home screen or invalid login screen.
IIS 7 server has .net framework 3.5SP1, but no MVC. So I deployed the System.Web.Mvc dll in the bin folder.
Here's my Code (I've omitted the views and models as they are not needed here):
[MyAppAuthorizationFilter] public class MainController : Controller { // // GET: / [code]......
I am using the below code where I put this tag on a .aspx page:
"<a name="tips"></a>"
Now if I from another page run the code in the hyperlink to navigate to this page2 where I have the above tag. The page will scroll down to this tag automatically where this tag will be at the TOP of the screen.
My question now is if it is instead possible to scroll to the position where you have this tag at the BOTTOM of the screen instead ?
I'm building a few webpages in my webapplication which use a webservice.While communicating with the webservice, which can take more than a few seconds, I want to display a loading screen. Something like the jquery dialog, where the background is disabled and a loading image appears in the middel of the webpage.
How would one create a website that would look the same at any resolution? I've heard of making so it will fit for a 800x600 screen but then that just screws everyone that has a higher screen resolution. I've heard about using widths that use percentages and using iframes and things like that.
What's the best way to have one website fits all resolutions?
So I am creating a log-in screen that is similar to that of Facebook's. In other words you can log-in but if you are a new user you can create yourself a profile quickly by filling in a few fields.
The problem I have is I want to put validators in to check that a user has completed all the necessary fields but the validators dont validate even if the user is not using that form. For example, if I filled in the create user form and pressed the create user button the page would not progress as the validators for the log-in section would say that there is no text in the username or password fields.
I was wondering if there is a way of fixing this. I thought that maybe you could write in the VB code something like:
IF btnCreateUser_Click = True
then
the required validators for the log-in section are set to true.
Is there a way to return to the previous view without having to record all the parameters that were used to get to the view in question. Consider this situation. You have a search screen with input parameters, you press search and get results displayed on the page. You click on one item to get a detailed look which redirects you to a new view. Does MVC have the ability to get the previous query string that contains the search parameters?
I got a bot and screen scrapper problem. I have successfully redirected them somewhere else, but they still show up in my stats. I run my redirection code in the pre init section of the master page. I use discountasp for my hosting provider. Is there a way to run my code before the preinit page section?
I added a button on my website and tried to use confirmbuttonextender. I inserted it and enabled it on the button but when I run the application and click the button, the page just posts back, no pop up message or anything comes up. What would cause this? I don't get any errors
<asp:Button ID="Button1" runat="server" Text="Button" /> <asp:ConfirmButtonExtender ID="Button1_ConfirmButtonExtender" runat="server" ConfirmOnFormSubmit="True" ConfirmText="Once data has been updated, it can't be retreived" Enabled="True" TargetControlID="Button1"> </asp:ConfirmButtonExtender>
I want to know that how can i make fit the page according to the screen size.
I am using master and child pages.
Before I already put the same question in the forum few months back but didnot get perfect answer. The solution I got from the forum is but it is not working fine:
[Code]....
I have published my website on intranet and checked on different sized monitors but the pages are not fitted according to the montior size.
With Menuitem in horozontal display mode, i want it to be displayed accross the top of the screen, filling the whole width - any idea how you specify this? I see there is a width parameter, but what value to use? Additionally, if say it contained 4 items say and I wanted to display the 4 items justified in the centre only of the screen - how would I do this?
We've been working with VS2010 for the last month now and everyone in our team is getting the same annoying behaviour. After VS has been open a while (couple of hours usually) we get the following issues:
- the text editor starts to stop redrawing as we type - Intelisense stops popping up - The status bar no longer updates
It doesn't matter how long we sit and wait, the screen never catches up, but if we alt-tab out and back again our changes are there instantly. That says to me its not a speed issue with either the processor or the graphics? Is it some kind of WPF bug?
I'm creating a optimized web page for mobile devices with C#. Is there a way to offer a page for larger screens and one for smaller screens on android devices? With Apple i can differentiate between iPad and iPhone, but how can I do this with the galaxy tab or a regular android phone?I don't want to use any javascript in this case.
