View 1 RepliesI 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.

i use this code to download the source of a page from a site
Dim MyWebClient As New System.Net.WebClient()
TextBox1.Text = MyWebClient.DownloadString("site")
but it doesn't work when i try to grab a site that has .php so how could i accomplish downloading the page source of a site that ends with .php
I've used this method tons of times, always worked but for some reason it does not work with [URL]..anyone has an idea what the problem is and how to fix (I tried also with just 'http://blinkx.com' did not work too or maybe other ways to get the source page of this website?

url...only after you have logged in (because then you can see your collected points)How can I do this? I tried the &password=.... thing after the url didn't work I also tried with [code]this would work but it's complicated because then you'll need to check if you are logged in, log in through webbrowser and then get source page, I think it should be possible faster..also how can I check if the page is completely loaded in a webbrowser control? now I usually go to a webpage and then continue my code in the [code]but this become complicated if I want to go to another website after that because then it starts from the beginning again and I need goto statement, etc this is really annoying and complicated after a while
View 1 RepliesWay 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:

Also if anyone knows a way to colour the tags.
Is it possible to display the page's source by opening notepad.exe (via Process.Start) and somehow set the text to the source?

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 1 RepliesAfter the client finishes testing, they go to the results page and then my program returns them back to the secondary page.If they re-enter the testing page again, for a second go-around, with out completely leaving the program as I have been doing since I was tweaking the code after each run, the repetition counter is not resting back to Zero. It�s still retains the information from the previous testing phase.
Example:The client chooses how many testing cycles they want to go through, from 1 to the total amount available to them to test. Right now its only 5.When they first start testing, it starts at �1 of 5�, then progresses at one increment for each drug they test on. Once they reach 5 and answer their final question, the program then goes to the results page and then to back the secondary page. If they choose to re-enter the testing page without totally leaving the program, the testing page counter sits at �5 of 5�. Shouldn�t the page be resetting the variables each time it loads?
I built a specialized userControl using VB2008 (on XP 32-bit) to embed in HTML (not ASP!) and compiled it, pointing to x86 CPUs. I added the necessary keys to the registry (see attachment) to declare a classId in a HTML 'object' tag. This scheme works OK on all 32-bit OS I could put my hands on, but fails to load on 64-bit: I could test only on XP and Win 2003. No error message and Fiddler does not even know something happened... I installed VS2008 on the XP 64-bit machine and ported the code to a fresh userControl (to check the code). I got the userControl running on this workstation without any trouble. I copied this new DLL on another workstation and added the necessary keys to the register, but to no avail. I checked the registry and the 'Wow64' keys are there allright. As a check (and to provide you with a 'working' example), I:
- built a very simple userControl on the 32-bit environment (label, textbox and button to display the text in a mMessage box),
- on the 32-bit workstation:
+ copied the file to a 'program files' folder,

is there anyway to get the page source with out complete loading the page?
View 3 RepliesI have made many web browsers that just navigate to a web page, I don't have any buttons or any thing like that as it is controlled via other software using shortcut keys etc.I have created a button in my other software that sends the keys strokes "Control" and "H" I can get this to navigate to a webpage by manually typing i the same page that it navigates to when the form loads, but this mean I have to type the address in twice for each browser I make. I first type the url for the browser to navigate to in the properties section in VB and this is nice and quick to type in each webpage and build quickly build a new browser for it. Currently I have to repeat that url in the browser_homebutton Private Sub, what I want to happen in the below Private Sub is that it navigates to what ever address is typed in the "URL" cell in properties of the browser. What should my "Then" statement say? [code]
View 2 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.

What this should do is get all the page source from the current web page from where I righ clicked and save it on the disk. Basically, "right click -> view source -> file -> saveAs ", this is what i want to do programmatically.

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?

The above code works fine on most of the websites I have tried to extract page source from but for some reason it is failing to extract the html contents of few websites like these where the message posted by a user is nowhere to be seen? The webpage in question is this: [URL]
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?
