I am using UiPath and am currently trying to extract data from a screen that looks like this:
When I use the Screen Scraping tool, I am able to get the data:
But when I add Get Full Text activity into my sequence and select the same region, the output to the variable is always blank.
Am I missing something here?
In the screen scraping tool the scraping method you are using is native, Whereas you are using Get Full Text activity which is equivalent forfull-text screen scraping method to retrieve the same in UIPath studio.
So try to use Get Visible Text activity (Equivalent to native screen scraping method).
I hope you know there are 3 scraping methods as below
Full-Text (Equivalent to Get full text activity)
Native (Equivalent to Get visible text activity)
OCR (Equivalent to Get OCR text activity)
Please let us know if you have further queries

Given a rectangle that represents an area on a Windows screen that contains text, what is the best way to extract the text?
I know that it is possible using OCR, but even after significant pre processing, the quality is really poor.
Getting the Window Text using Win32 API does not always work as well.
Assuming that the text was rendered using a font, is it possible to get it from there?
Any directions would be extremely helpful. Thanks!
Given a rectangle that represents an area on window screen, the best way to extract text is indeed OCR. Use a better OCR library like this one from Microsoft.
The reason getting the window text using Win32 API does not work well is because there may be multiple windows in that rectangle. You will have to find out what all windows the rectangle contains and send a message to get the text for each window. It is not impossible but difficult to do and even if you manage to do that, you will run into issues of text alignment, etc. OCR is your best option.
It does seem possible without using OCR, as NirSoft SysExporter can do this:
https://www.nirsoft.net/utils/sysexp.html
This may be suitable for programmatic use as it can be run from a command line:
Starting from version 1.70, you can export the content of Windows
control from command-line, without displaying any user interface.
You may not be able to target it at a specific rectangle on the screen, but maybe the same result could be achieved by first scraping everything followed by some post-processing.
Further basic info:
SysExporter utility allows you to grab the data stored in standard
list-views, tree-views, list boxes, combo boxes, text-boxes, and
WebBrowser/HTML controls from almost any application running on your
system, and export it to text, HTML or XML file.
...
Known Limitations
SysExporter can export data from most combo boxes, list boxes,
tree-view, and list-view controls, but not from all of them. There are
some applications that use these controls to display data, but the
data itself is not actually stored in the control, but in another
location in the computer's memory. In such cases, SysExporter won't be
able to export the data.
Personally I've used it to grab text from what look like label controls.
I have a list of images that I am currently looping through.
Is it possible to have a command where I can put in the location of text that I am trying to extract or show it with something like Citrix Scrape on what data I want to take out?
The Get OCR Text action requires you to provide a UI element. One simple option is to loop over all images, then open them in an image viewer of your choice, and then use the Text -> Scrape Relative to extract your invoice number into a variable.
You can use the Desktop Recorder for all actions mentioned above. Note that you will have to adjust the Selectors, as the Recorder usually considers the text the application title as well (which will often include the document's name, and that's not what you want as all your invoices will have different names). You can just open another invoice in your application, then open the Selector and Attach to Live Element to let UiPath work out the Selector for you - which works just fine in most cases.
Depicted below: a sample sequence created with the Desktop Recorder. Here I just read the invoice number with OCR, and I use IrfanView to display them. Of course you may want to increase the zoom level to enhance your OCR results in a real-world scenario.
I used this code to display multiple images in the same namedWindow. Now I want to display some of the calculation results (that I have calculated before with image processing functions).
The results should be displayed in the fourth position of the namedWindow, like I show in the red square in the image below:
Is there any way in opencv that can throw console window in the namedWindow? Can I copy the results from console window in any other way on the named window? Is it possible to create somehow scrolling window with all information and put them on ?
I would suggest creating an new Mat with either ones() or zeros() and then using the function putText to insert your text.
Afterwards show the Mat like the rest before
Hi every One See the Below Image
in this Screen that 3 Blocks are images and i am trying to Bind some text to that Text Block and display with some time intervals with Live tile Look and feels. Can any One Sugest How can i do this
If you want to mimic Live Tiles, I suggest that you take a look at The Windows Phone Toolkit. It contains the HubTile control which is live and is probably the thing you are looking for.
If not, you have the source code and you can check how they did it. This way you can replicate the behavior and then customize it.
I'm developing a WP7 app that has a lot of math content, and I need to display expressions as images.
The data for these expressions is in the form of strings like this:
"d=\\sqrt{2} \\times a"
"A=a \\times \\frac{\\pi}{4}"
etc.
The goal is to take a string like this, run it through some parser of some sort that then outputs an image of the expression in LateX style.
Does anyone know of some magic code I can include / have a solution?
Much appreciated.
A possible solution without getting Tex to run on windows 7 phone, would be to use a web service.
You would post your equation string to a web service and it would reply with the image data or a url. Example
In the event that tex for windows 7 phone exists, that above mentioned page also links to a script called tex2im which shows how to create an image from tex code.
