I need to access to a webpage, and load its content out as a HTML text format, the problem is, when i right click and choose view source, it return me a correct document text, but when i try to access it with VB.NET, i encounter a problem which it cannot return the content as view source do, because the content is a source in a frame, like the following.
[Code]...
What i need to know is how to refresh/load a single frame and not the whole page.[code]...
View 6 RepliesIs it possible to load the page source of a website without loading the page using webbrowser?
View 1 RepliesI'm trying to get the HTML from a frame in a website which is loaded into a WebBrowser in my application.
I have this WebBrowser so that the user can login easily by putting the username and password on the login form of the page so that i can get the HTML code from the protected page.
However, i have to read the frame code while the WebBrowser being on the main page because if i enter the frame, it redirects me to the main page again so there is no way of reading the frame code by entering it.
So i don't know how to read the frame HTML code of a website[url]...
I currently have a main page called "ShowFrames.php" that has this html code in it:
[Code]...
I have loaded "ShowFrames.php" onto my WebBrowser1 control and it loads both of the frames onto the webbrowser control. Now my question is, how can I get the source of either of the iframes WITHOUT loading that frame by itself? For instance, when you load 2 frames on a screen in Firefox, it lets you right click on it, and select "This Frame" > "View Source" so you can view the sources separately. Can anyone tell me how I can duplicate this and put the source in variable strSource? I know that to get source code for a page, you need this WebBrowser1.Document.Body.InnerHtml But I dont know where to go from there in order to get a specific iframe's source.
I have just a form in my VB.Net project and even when I try debugging that - there is nothing going on besides the form being loaded - I get the error: No symbols are loaded for any call stack frame. The source code cannot be displayed.
View 3 Repliesi'm trying to make the program wait while the webbrowser document frame loads. I'm using the code below, but all that happens is the page load pauses while the do loop happens (which obviously will be neverending as the search function searches for a line of html particularly present in the page i'm waiting for the webbrowser to load).
[Code]....
Way to space out the source code of a web page, having each tag on one line, without having to search for each tag ending and then making a new line after.
My code for obtaining the source code is:
CODE:
Also if anyone knows a way to colour the tags.
I have multiple iframe items on a page (vb.net based application), in particular, one is a frame that holds links that generate the details frame. Currently the javascript is working for IE but when used in any other browser it does not work correctly. Here is the line that is causing this errorwindow.parent.detailFrame.location.href = form + "?cat=" + cat + "&par=" + par + "&HighlightID=" + HighlightID;I can tell this line is incorrect in firefox because when placing alerts in the function after this line, they do not fire, but they do in IE. can anyone see what needs to be done for this to work in both firefox and IE?
edit:
i am able to use items like
window.parent.getElementById('detailFrame').location

One of the great features of Page Frames in the now discontinued FoxPro language was that you could use a Page Frame (like a TabControl) and hide the tabs. The nice thing about this was that if you wanted (for example) to have simulated "frames" you could use a Page Frame control, hide the tabs, and that gave you endless frame that you could then access programmatically.I need to do something along the same lines. To further illustrate, if you look at any configuration screen in Office 2007, they all have a ListBox on the left, and then clicking on those Listbox selections brings up "frames" on the right with what you want to work with.This is the effect I want to create - but in .NET I cannot see a good control to use.
Panels - these seemed a good idea at first, but even when set to Visible and not Visible these frames hide each other so they dont seem like they will work.
GroupBoxes - Tried these but the same problem as with panels.
TabControl - Tried this, and it works great - but I DONT want the Tabs. Instead I want non-tabbed pages, that would then be like frames.
What is the best control to use? And, can I hide the Tabs somehow in the TabControl?

View 3 RepliesDoes anyone know why a Page_Load would be called twice on a page when requesting an aspx page?I am using .Net 2.0 with the new .net 1.1 compilation model installed. Whenever I request a page, the Page_Load on the aspx page appears to be called twice, so does the Page_Load on and user controls added to that page.

View 3 RepliesI have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
'Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1))
'Response.Cache.SetValidUntilExpires(False)
'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.
I have a page to which i send some variables with the GET method. In my VB back-end i get those variables using Page.Request.QueryString("<name>")If i then use the IsNumeric method to make shure it is an numeric string i get True back as value.
When i then try to transform the string to an Integer using val, cìnt, Integer.Parse or cType I get an error saying that my string could not be converted to a integer.So i made an error page which gives me all the info i need to deal with the problem (view below) Exception Message: Conversion from string "" to type 'Integer' is not valid.
[Code]...
IsNumeric confirms that it is a numeric string and that it should be convertable to an Integer. So why won't it work. I don't think that my code should provide any extra information because it only gets the querystrings, uses IsNumeric and then tries to convert them.

View 6 RepliesI need to get the source of a webpage that my browser control has loaded.
Whenever i use browser.document.htmltext or anything like that dont get the proper source that i need.
The URL is masked so i can't use some sort of HTTP response request to get the page source.
The website only works with IE and does not behave normally like most sites.
The only way I've been able to get the source that i need is right clicking the webpage in my browser, and selecting "View Source".
How can i do this "View Source" programmicatally so i can work with the source code of the web page?

Is there something I have missed or is it due to forum protection etc which is preventing the vb application from extracting the whole page source?

View 13 RepliesI'm writing a program in VB.net that gets the source code of a web page with a video on it. it then uses regular expressions to isolate the download link of that video. then it uses "httpwebrequest" and "httpwebresponse" to download the video. my problem arises when certain sites have a page where you have to click continue in order to get to the video page. [URL].. called "The.Matrix.Reloaded.2003.mp4" so i tell my program to get the source code for the url [URL]..but it cant find the video's download link because it's searching for the file in the "continue" page's source code. you can see what i am saying by going to that website above and viewing the source code by right clicking on it. and then click continue and do the same when the video appears and you'll notice that the file is only there in the second one.
So my question is how can i get the source code for the page that the video is playing on and not the page where i have to click continue?
