QUESTION
I am writing a C# Winforms program that uses the WebBrowser control. In my program I use the Navigate function whenever I click on a link in my webrowser page so I can create some text and assign it to WebBrowser.DocumentText. This works fine. However, the program also can execute a WebBrowser.Navigate(url) function which creates a program loop as it keeps coming back through the OnNavigate function as shown below:
...ANSWER
Answered 2021-Mar-31 at 01:26When you set the onNavigate event to a handler, you can saying, whenever I navigate, run this function.
The only reason I can see a looping happening is that you are calling another navigate in the event handler. So check that a navigate call doesn't exist in the call stack either in the event handler or a function called by the event handler.
If that's the issue and the intent of the handler is to do something to the url before navigating, you are probably using the wrong event and need a beforeNavigate event or a Navigating event which allows you to cancel the navigation or modify the url before navigation.
In any case, if you can't find where you are looping, what you can do is to set a variable for the whole form e.g.

I am trying to deploy my Django project using Ubuntu and apache webserver. When I transferred my project to the Ubuntu web server and tested it in development, everything went fine. However when changed to production, I experienced file not found problem and I suspect this problem is related to my setings.py, but I am unable to troubleshoot it further. The error I see in production when accessing my site is:

Answered 2021-Mar-13 at 12:58It is as commented by Ivan Starostin that one should give the absolute path in to the file in the production environment. Also using reverse url can also work in this case as suggested in the comment.
QUESTION
Hello guys!
A friend of mine has to do a lot of typing for school in her IT classes. That means, she has to learn how to type fast on the keyboard. As lazy as she is, she asked me if i have any idea how she's able to type her texts on https://at4.typewriter.at/index.php?r=site/index without actually doing something. I thought to myself "hey thats a cool idea, I'll look into it".
This is how the website looks like
Thats the website where she has to type. There is a
The problem I am facing is that i have no Idea how to scrape data from a website that already has been opened in a webrowser / that already has been edited / that already has been interacted with. I'm happy about any advice or solutions!
Thanks!
...ANSWER
Answered 2020-Aug-13 at 00:13Normally, you'd have people asking for what you've tried so far and your code, but I understand you're really in the dark on how to even get started with this problem.
If you need the Python script to be able to step in after the user has interacted with the site, you're in for a massive challenge. There are many variables, like what browser is being used, on what operating system, at what resolution, with what settings, etc.
Interacting with a live application will be fairly hard, although not impossible. If the site can be operated entirely using the keyboard and you can find some reliable sequence of keyboard inputs that find the right controls to send input to, that could be an approach and libraries like pywin32 could provide access to the API call you'd need to send input to the screen.
However, a better approach may be to just cut out the user altogether and have the script perform all the interaction. You can do that through something like selenium and a driver like ChromeDriver that basically allows you to operate a website, with all its scripting, like a user would.
You should probably look into either of these approaches and come up with a basic attempt to ask more specific questions if you run into problems.

QUESTION
I need to get the current calculated style of element in winform webrowser.
get the element:
HtmlElement em = webBrowser1.Document.GetElementById("theIdOfElement");
now to get the style i can use:
var style = em.Style
or
var style = em.GetAttribute("style");
the documentation says that the style property "Gets or sets a semicolon-delimited list of styles for the current element." so the result should look something like: "font-weight:bold"
But the result i get in first case is "null" and in second its "System.__ComObject" From what i understand, if the style is in html for example :
than the result is "color:red" but when the div style is affected by CSS than the result is null.
Is there a way to get the current style of Htmlelemnt even if the style is only in CSS file ?
If i cant get the current style is there any other way to determinate if the htmlelement is visible ?
...ANSWER
Answered 2020-Feb-11 at 08:55The style property returns the value that you have explicitly assigned to style.
To get the computed style, you can use currentStyle property of element or getComputedStyle method of the window.
The following code get computed background-color and computed color for an a element:
QUESTION
I'm generating a PDF from a HTML form using mPDF. The form contains a couple of textarea tags (among other things). If the user doesn't enter anything in one textarea (they don't have to), that textarea doesn't show up in the PDF.
This is what it looks like with text in the textarea:
This is what it looks like without text:
I would like the empty textarea to show up as an empty box in the PDF. It looks fine in the HTML page, but not in the PDF.
I've tried the following:
- Entering a blankspace in the
textarea. - Styling the border with CSS: "
border: 1px solid #000". - Setting the font colour of the
textareato white using CSS ("color: #fff") and adding some text to it. The text is white in the HTML, but in the PDF it shows up as black.
Is there a way to make mPDF render a textarea without text as an empty box, just as it looks in the webrowser (I'm using Firefox btw.)?
...ANSWER
Answered 2019-Nov-20 at 11:07Adding a to an empty textarea forces mPDF to render it.
Thanks to Delena Malan for pointing this out!
(I guess that I should've checked the issue tracker for mPDF before asking this)

The iss express was in 32-bit and it should be configured in 64-bit for manage big amounts of memory.

QUESTION
I developed a simple windows form app that displays a webpage inside a Gecko webrowser. It works fine on my computer(win10, visual st.2017), I also tried it on another computer running win10 and it also runs fine, but when I tried running it on the client's computer it just won't launch, as if nothing happens, the cursor changes to a circle(thinking) and then nothing.
I installed .net 4.6 no change, disabled antivirus no change, installed firefox no change. Tried another winforms app that simply opens an empty window and it works fine, and another console application works fine, it's just this app that uses Gecko webbrowser that doesn't work.
I tried simply copying my bin\debug folder and running the app, and I also tried installing the app from the setup.exe after making a release version also won't run, it gives error that plugin-hang-ui.deploy.exe not found, I have plugin-hang-ui.exe in Firefox folder under bin\Release.
