I want to ask if there is a way for me to get like a web element content. What i mean is:
the site
the program
You don't need to type the site address or where the element is, in need it only in this case(fully empty site with a few words only).
My question is that, wets say that you have a text on a webpage, and you want that text to appear in a textbox...That's it
you can use this :
Dim We As New System.Net.WebClient()
textbox1.text = We.DownloadString(_Url)
We.Dispose()

I'm creating a sample textbox for search like this (I'm using VB) in my webpage:
Dim txtSearchFilter As New HtmlGenericControl("input")
With txtSearchFilter
.ID = "txtSearchFilter"
.Attributes.Add("placeholder","Filter")
.Attributes.Add("type","search")
.Attributes.Add("maxlength","80")
End With
It's great, because this is the HTML5 style box which has some useful features, such as the "x" on the right side of the box to clear the text entry. However, from the code behind, I can't retrieve the text that was entered. I've tried:
txtSearchFilter.InnerText
txtSearchFilter.InnerHtml
txtSearchFilter.Attributes("value")
Request.Form("txtSearchFilter")
But none of these work. Is there a way to get the value?
P.S., SO prevents me from selecting the HTML5 tag and, instead, puts in the HTML tag even though I selected the HTML5 tag.
Add a name attribute to the input element.
txtSearchFilter.Attributes.Add("name", "txtSearchFilter")
Then on postback, you can retrieve the value by Request.Form(name_attribute). Example based on the above code :
Dim value as String = Request.Form("txtSearchFilter")
I'm creating a blog application similar to scoopwhoop or mensxp.
Basically I want to create my database in such a way that I can assign image a particular position in the article.
look at this page https://www.scoopwhoop.com/Move-Over-Tony-Stark-Marvels-New-Iron-Man-Is-A-15YearOld-Black-Girl/
or http://www.mensxp.com/health/weight-loss/31372-5-rules-of-fat-loss-that-most-people-ignore.html
you see, in these pages we have some text then a relevant image then again some text and relevant image to just above text and so on.
I mean it should make sense that a particular image comes just before or after the related text.
Currently I'm doing this way
class Post(TimeStamp):
title = models.CharField(max_length=127)
text = models.TextField(verbose_name='full text description')
# some more fields
class Pictures(TimeStamp):
image = models.ImageField(upload_to=upload_to_image_path)
post = models.ForeignKey(Post, related_name="picture")
this schema will create two tables one for blog post and other of images used in posts.
now here I can randomly put images in a post... like count no of words in a post and number of images associated with this post and then use basic math to divide the text in equal length and put images after every blog in frontend. but it wont solve the problem.
I tried to use django_summernote as well but created some other problems so discarded that option.
How do you think I should design my schema so that I can solve this problem and may be i should be able to use django admin smoothly.
I would throw out the Pictures() class altogether. The images should be a part of your post body. So an example entry would be...
title = "How to program an awesome site with Django!"
text = "<p>This is some text.</p><img src='image link'><p>This is some text after the image</p>"
Basically, the images are just as much a part of the post body as the text. There is no need to create a separate database table.
So in summary, this should be your database setup...
class Post(TimeStamp):
title = models.CharField(max_length=127)
text = models.TextField(verbose_name='full text description')
# some more fields
And the post body as a whole should all be contained within the text field.
Having trouble getting access vba to set a word document's header properly. I've got this.
oDoc.PageSetup.DifferentFirstPageHeaderFooter = True
oDoc.Sections(1).Headers(wdHeaderFooterFirstPage).Range.InlineShapes.AddPicture "C:\Users\mr.helpless\Pictures\doody.jpg"
oDoc.Sections(1).Headers(wdHeaderFooterFirstPage).Range.Text = "hello there"
oDoc.Sections(1).Headers(wdHeaderFooterPrimary).Range.Text = "whooo hooo!"
What happens right now is the text will replace the picture for the first page (subsequent pages are fine).
I need to have the picture and text - and I need to offset the picture to the left about half an inch while text is centered with normal margins.
Any idea how to go about it? Basically I need to set a document letterhead with a logo.
Update
Dim myText As String
myText = "hello there"
With oDoc.Sections(1).Headers(wdHeaderFooterFirstPage)
.Shapes.AddPicture Filename:="C:\Users\mr.helpless\Pictures\doody.jpg", LinkToFile:=False, SaveWithDocument:=True
.Range.Collapse
.Range.InsertAfter (myText)
.Range.Font.Name = "Helvetica"
.Range.Font.Size = 8
.Range.Font.Bold = True
.Range.Paragraphs.Alignment = wdAlignParagraphCenter
End With
I've got half of it done, now I just need to position the image to -.5 to margin.
Completed Solution
Just add "Left:=-35" to the picture like such (or whatever value works)
.Shapes.AddPicture Filename:="C:\Users\mr.helpless\Pictures\doody.jpg", LinkToFile:=False, SaveWithDocument:=True, Left:=-35
Have you tried recording a macro in Word that does the rough reposition - then bring the code over to Access and edit it for the correct object and size?
All of it is updated in the original thread. it took using the .Range Collapse to add in text along with the image and it took putting Left:=(value) to move it where I needed it.
I didn't know how to phrase the title, so sorry about that. If you have a better title suggestion, let me know and I'll change it.
I've got a chunk of text that is displayed as HTML in a TextField. An example of this text is this:
1
<font size="30" color="#FF0000">When your only tool is a hammer, all problems start looking like nails.</font>
</br>
2
<i>99 percent of lawyers give the rest a bad name.</i>
<b>Artificial intelligence is no match for natural stupidity.</b>
<u>The last thing I want to do is insult you. But it IS on the list.</u>
</br>
3<showimage=Images/image1.jpg>
I don't have a solution, but I do admire the problem.
The only substitute for good manners is fast reflexes.

Well, here I am! What are your other two wishes?
Most of the tags are basic, meant to display what I can do formatting wise. However, since Adobe Air has a sandbox that prevents inline images (via the <img src='foo.png'> tag), I've had to come up with another way to display images.
Basically, I intend on having an image displayed somewhere on the screen, and as the user scrolls the image will change based on where in the text they have scrolled to. The image can be a background image, a slideshow on the right, anything really.
In the snippet above, look for my custom tag <showimage=Images/image1.jpg>. I want to get the local y position of that tag once the TextField is rendered as HTML and word wrapped. The trouble is, when I query the y position of the tag (using getCharBoundaries), I can only either search for the tag when I render the text as a .text instead of a .htmlText. If I search for the tag in the TextField after rendering it as .htmlText, it doesn't get found because the tags are hidden and replaced with formatting.
The trouble with the y value I get before rendering the HTML is that the y value will be different due to font sizes, tags being hidden and word wrap changing the line and y value that the tag is located at.
How do I get the correct y value of an HTML tag once the HTML has been rendered?
I've considered using a different style tag, maybe something like &&&&&showImage=Images/image1.jpg&&&&, but that seems like a cop-out and I'd still run into problems if multiple of those tags were in a block of text and the tags were removed, followed by word wrap that shifts lines in a pretty unpredictable way.
myTextField.textHeight tells you the height of the text in pixels. So you can split the string on whatever you're looking for, put the text before your target in the textField and get the textHeight, then put the rest of the text in.
Here's some example code - tMain is the name of the textField:
var iTextHeight: int = 0;
var sText: String = '<font size="30" color="#FF0000">When your only tool is a hammer, all problems start looking like nails.</font></br><i>99 percent of lawyers give the rest a bad name.</i><b>Artificial intelligence is no match for natural stupidity.</b><u>The last thing I want to do is insult you. But it IS on the list.</u></br><showimage=Images/image1.jpg> I don\'t have a solution, but I do admire the problem. The only substitute for good manners is fast reflexes. Support bacteria - they\'re the only culture some people have. </br>Letting the cat out of the bag is a whole lot easier than putting it back in. Well, here I am! What are your other two wishes?';
var aStringParts: Array = sText.split("<showimage=Images/image1.jpg>");
for (var i = 0; i < aStringParts.length; i++) {
if (i == 0) {
tMain.htmlText = aStringParts[i];
trace("height of text: " + tMain.textHeight);
} else {
tMain.appendText(aStringParts[i]);
}
}
sText gets split on the tag you're looking for (removes the text you're looking for and breaks remaining text into an array). The text leading up to the tag is put in the textField and the textHeight is traced. Then the rest of the text is put in the textField. This gives you the y pixel number you need to arrange things.
Let me know of any questions you have.
Instead of going through the trouble of parsing your image tag, have you tried playing with HTMLLoader and using the loadString method? This should load everything in its proper place including the image using the img tag.
private var htmlLoader:HTMLLoader;
private function loadHtml(content:String):void
{
htmlLoader = new HTMLLoader(); //Constructor
htmlLoader.addEventListener(Event.COMPLETE, handleHtmlLoadComplete); //Handle complete
htmlLoader.loadString(content); //Load html from string
}
private function handleHtmlLoadComplete(e:Event):void
{
htmlLoader.removeEventListener(Event.COMPLETE, handleHtmlLoadComplete); //Always remove event listeners!
htmlLoader.width = htmlLoader.contentWidth; //Set width and height container
htmlLoader.height = htmlLoader.contentHeight;
addChild(htmlLoader); //Add to stage
}
Another approach is to search your html string for <showImage ..> tags and replace these with shortcodes e.g [showImage ..] , before inserting the htmlString in a textField. Then this is NOT xml but text and you can retrieve the y value (that is if i understand correctly your issue).
Then the rest of your code can take it from there.
(ps using HtmlLoader seems nice alternative though)
I have grabbed the text from a webpage, and put it into a TextBox using:
TextBox1.Text = WebBrowser1.Document.Body.InnerText
Now in that text box, I have :
Show Me HowDevice Status
ORDER CARTRIDGE LESS THAN 700 PAGES
Help
Pause/Resume Continue
I want to be able to grab the "ORDER CARTRIDGE LESS THAN 700 PAGES" from the textbox, and put it as the text to TextBox2.Text
I have been looking for ways to do this, but I'm just not finding any resolution. This is the simplest amount of text I can get the page down to. This text can also change depending on the printer's status. So I'm basically looking for a way to get the data between Status and Help, and assign it to another textbox's text. I hope this makes sense... If it's easier to get it from the HTML please assist me with that. Below is some of the code from the HTML of the page.
<div id="Text1" style="font-size:14px; padding-top: .7em; padding-bottom: .7em;" >ORDER CARTRIDGE
LESS THAN 700 PAGES
</div>
To answer your specific question:
If you have a good reason to display the whole text in textbox1, and the string you require is always the second line:
TextBox2.Text = Textbox1.Lines(1)
To get direct from the browser:
TextBox2.Text = WebBrowser1.Document.GetElementById("Text1").InnerText
But as the others have mentioned, there are probably better ways to accomplish your task.
What exactly are you trying to do?
