I am working on an app that reads XML and displays content accordingly with whats contained n the XML. Now i have the XML part done but i need one other part and that is to load a Small section of html code into a web browser element. Is there anyway for me to either dynamically create a html file (i was thinking maybe create one and save in storage then load from there?) or directly insert code into the web browser element.
Failing this i'll just create a php page on my server that adjusts according to value its passed.
You can store your entire HTML code in a string variable and call the NavigateToString method.
myWebBrowser.NavigateToString("myHTMLcode")
How you create the HTML string depends on your app but you could store a basic template and use String.Replace to replace any particular items in the code.

How can we access the content after class="hidden_elem" using selenium, as it does not get loaded into the page source while accessing it. The content in the comments is actually what we need to extract as they are a part of the script that gets run.
I have an ASP.NET Web API web service which I want to use for file uploading. The way I do this is that the client posts a JSON object to the service at http://myserver.com/api/images/upload .
The object would contain a base64 string representation of the image, plus some metadata, e.g:
{ companyId: 12345, image: "someBase64encodedStringRepresentingTheImage" }
I would like to use TinyMCE on the client side, but I can't figure out how to customize it such that images are uploaded to the server in that format. (Actually, it doesn't seem like TinyMCE comes with an image uploader at all)
TinyMCE 4.2+ actually has its own built in process for handling the upload of images that you place in the editor:
https://www.tinymce.com/docs/advanced/handle-async-image-uploads/
The basic process is that TinyMCE will create a separate HTTP POST for each image that you insert into the editor. It will send that image to a URL of your choosing (via HTTP POST) based on the setting of the images_upload_url option in your init.
The image handler at the URL referenced in the images_upload_url (which you have to create) has to do whatever needs to be done to "store" the image in your application. That could mean something like:
Store the item in a folder on your web server
Store the item in a database
Store the item in an asset management system
...regardless of where you choose to store the image your image handler needs to return a single line of JSON telling TinyMCE the new location of the image. As referenced in the TinyMCE documentation this might look like:
{ location : '/uploaded/image/path/image.png' }
TinyMCE will then update the image's src attribute to the value you return. If you use the images_upload_base_path setting in the init that will be prepended to the returned location.
The net here is that TinyMCE knows when an embedded image exists in your content but it can't possibly know what to do with that image in the context of your application so that job (the "image handler") is something you must create.
There is an option for you to write your own image handler if the default one is not sufficient:
https://www.tinymce.com/docs/configure/file-image-upload/#images_upload_handler
I would recommend trying to use the uploader that comes with TinyMCE so you don't have to write and maintain your own code going forward (always easier) but if the built in code is not appropriate you can indeed replace it with your own function.
I´m using AspPDF together with Classic ASP to create PDF files and I have a page that is build dinamically based on POST requests.
After that, I need to get this HTML that has been dinamically created and insert all of it inside a variable, so then I can send it to AspPDF method at the end of the page.
(I know AspPDF has a method that converts page based on URL, it does not work for me in my specific case)
Because I have several if statements and loops, I have no idea how to store all current HTML generated in a variable.
Any ideas on that?
Thanks
i am not familiar with AspPDF, but my question is:
can you store everything in some variable and once html completly generated then send content by using
Response.Write VarHTML
Because I have several if statements and loops, I have no idea how to store all current HTML generated in a variable.
like this:
VarHTML = VarHTML & "your html code"
VarHTML -- just variable you create
I want to invoke a procedure in one page and use it in another page, and the response is only used by the next page, so I think JsonStore is not suit for that. Should I define a global var?
Is there any code sample to do such things? Thanks for your help.
I presume by pages you mean different HTML files. If so, that is not recommended, Worklight is intended for single page applications. There are no code samples that show how to do that.
I would recommended having a single HTML page and using something like jQuery.load to inject new HTML / DOM elements. By dynamically injecting new HTML your single/main HTML file shouldn't be too big and you can destroy (i.e. remove from memory / the DOM) unused DOM elements. Searching on Google for page fragments and html templates could help you find examples. The idea is that you don't lose the JavaScript context.
Maybe you can get away with doing a new init to re-initialize JSONStore (it won't delete any the data, just give you access) on every new HTML page and use get to get access to the JSONStore collections to perform operations such as find.
I need to find a way to write a program (in any language) that will connect to a website and read dynamically generated data from the website.
Note that it's dynamically generated--it's not enough to get the source html, because the data I'm interested in is generated via javascript that references back-end code. So when i view the webpage source, I can't see the data. (For example, go to google, and do a search. Check the source code on the search results page. Very little of the data your browser is displaying is reflected in the source--most of it is dynamically generated. I need some way to access this data.)
Pick a language and environment that includes an HTML renderer (e.g. .NET and the WebBrowser control). Use the HTML renderer to get the URL and produce an HTML DOM in memory (making sure that scripting is enabled). Read the contents of the HTML DOM after the renderer has done its work.
Example (you'll need to do this inside a System.Windows.Form derived class):
WebBrowser browser = new WebBrowser();
browser.Navigate("http://www.google.com");
HtmlDocument document = browser.Document;
// extract what you want from the document
I used to have a Perl program to access Mapguide.com to get the drive direction from one location to another location. I parsed the returned page and save to database. If the source never change their format, it is OK. the problem is the source format often change, your parser also need change.
A simple thought: if we're talking about AJAX, you can rather look up the urls for the dynamic data. Then you can use the javascript on the page you're talking about to reformat this.
If you have Firefox/greasemonkey making a DOM dumper should be a simple matter.
