Why is the Webbrowser control DocumentComplete event fired for top level frame first?

阅读更多关于 Why is the Webbrowser control DocumentComplete event fired for top level frame first?

Based on this article on MSDN: How To Determine When a Page Is Done Loading in WebBrowser Control , and from past discussions on StackOverflow, I would assume that in case of a document with multiple frames, the DocumentComplete event would fire multiple times, and the last time would be for the top level frame. However, using the exact sample code from the above-mentioned MSDN link, I find that if there are multiple DocumentComplete events when doing a Navigate to a URL, the condition is satisfied in the following code the first time, not the last time as the article seems to indicate.

Webpage navigation with persistance - ASP.NET C#

阅读更多关于 Webpage navigation with persistance - ASP.NET C#

I have a website that is already completed in ASP.NET. I need to add a section at the bottom that holds a live streaming video chat (Flash Object), and I need it to persist over different page visits. e.g. I have profile.aspx and local.aspx that might be visited and I need the little chat frame at the bottom to persist between page changes. Here's a pic: alt text http://c3gl.com/pageper.jpg The only ways I can think to do this are... Make the whole website on page that just dynamically loads what it needs. or use a bottom frame maybe? (not a fan of this idea) Is there any other way to do this,

Matlab has the following guide to making a movie in avi format. My goal is to be able to play the video in my presentation through powerpoint. nFrames = 20; % Preallocate movie structure. mov(1:nFrames) = struct('cdata', [],... 'colormap', []); % Create movie.

However I dont understand how to

I have a website which I host myself. I do not have a static IP address so I have all traffic for my domain forwarded with masking to my DDNS account.

I've been trying to find some free and working code on the net about how to send and receive data (or frames as its seemed to be called) to and from a specific USB device by using VID and PID. Does anybody know how to do this in delphi? There seems to be nothing about this for delphi, at all! LU RD See Robert Marquardt's HID controller suite for Delphi . It will give you communication possibilities with a USB device. This unit is incorporated in Project Jedi as well. See also Jan Axelson's HID page for examples. I think he has written book also.

How to detect if a site cannot be embedded via iframe?

阅读更多关于 How to detect if a site cannot be embedded via iframe?

I'm trying to embed some random sites in an iframe. I'm getting this error: Refused to display document because display forbidden by X-Frame-Options. I'm willing to respect their wishes and not embed it, but I'd like to be able to detect that this is set, so that I can try and reload another page. Is there an easy to way to do this in Javascript? You can do it either using CURL server side or using AJAX request. Either way, the idea is that you make a request to the website in question and simply check whether the response contains X-Frame-Options . 来源： https://stackoverflow.com/questions

The new simulator comes with the frames that make it look more like a phone in Xcode 9 beta. Is there any way to remove this frames and make it look more like the simulator in Xcode 8?

WPF - pagination when printing a visual

阅读更多关于 WPF - pagination when printing a visual

问题 I have a WPF window with a frame. I have some code to print out the content of the frame using the printdialog and printvisual. But this will only print what appears on the screen even though the frame scrolls and other parts are available. Is there a way to add pagination and make sure that the entire content of my frame will print. Or is there another way to take my frame content and print it? i.e. to not use printvisual? 回答1: Yes. I've done this. It is not very difficult. Wrap your Frame

Auto Layout vs Frame Sizes

阅读更多关于 Auto Layout vs Frame Sizes

So I'm slightly embarrassed to ask this because it seems so rudimentary but ever since beginning iOS development (about a year of self/internet teaching), when not using storyboards, I have relied heavily on frame sizes and used auto layout very sparingly. In Objective C I find myself in situation where I need to use Auto Layout more often but with Swift I can animate a frame's x and y origins, its center, etc... I have never run into a situation where I could not accomplish what I want with frame sizes and pixel locations alone and I have done some fairly complex view work. My question is,
