I want to use barcode to read instead of using input from keyboard. I use Key Enter trigger and passing null against it but it did't fire. Any solution.....
I Googled for it and found this article. The pertinent line is
"In order to cause the key-next-item to execute you will need to ensure
the bar code reader sends a TAB key sequence at the end of each scan
so that the key-next-item trigger will fire."
I don't know whether that will solve your problem but the solution will probably be something along those lines: configuration of the reader.

I need to add printing functionality on a zebra zq520 bluetooth thermal printer.
I manage to do so using the flutter_blue plugin but I am not happy with the implementation.
I hate to break the string to smaller chunks in order to pass through bluetooth (and wait!!!!!).
I was wondering if there is a better approach, like the one we used in the (good?) old days of java for android using the android.bluetooth.BluetoothAdapter class
Thanks.
I ended up creating my own plugin.
source code
EDIT: 2021/11/29 integrate some comments from comments section
This code is not limited to zpl. In theory it can support every printer language that sends clear text to bluetooth serial
It is only for Android
For this source code to works as is:
You have to pair a bluetooth printer with name that starts with "zebra"
You have to send the zpl commands as string.
The easiest way to check that your zpl command is valid, is by using the ultra useful labelary viewer. The easiest way to test a label layout (font size, images, barcodes etc) is by using the above free service. in fact all you have to do, is to create the layout you need in labelary and the just copy the entire string from first ^XA to last ^XZ to FlutterCblue.printToBT. For example if you send this
printToBT("^XA

You will get this:
One more thing: keep in mind that if you want to print special language characters (I need to print Greek) you have to find the correct font that is installed in your printer. For example: In order to print Greek characters I have to integrate this
^CWN,E:TT0003M_.FNT
just after the first ^XA. Then I use the N font in order to print Greek. It is very flexible if you understand the basics
Hope it helps
I used the below code:
web.sendKeys(Keys.chord(Keys.CONTROL,"a"));
web.sendKeys(Keys.BACK_SPACE);
This method almost worked, it cleared first, and is entering an alphabet a, dont know y, I tried element.sendKeys(Keys.Delete); but still no luck, attached is the screen after the method was executed.
enter image description here
The clear function should provide what you're looking for:
element.clear()
Documentation on this can be found in the official Appium documentation.
element.clear() would work but if you actually need to delete something you can use exactly what you have except like this
web.sendKeys(Keys.chord(Keys.CONTROL,"a"));
web.sendKeys(Keys.BACKSPACE);
no _ in BACKSPACE
keep in mind if you want to delete a characters before the cursor use Keys.BACKSPACE, to delete characters after the curser use Keys.DELETE
I am trying to create a Hierarchical block using the GNURadio Companion GUI. Answers I've found in other posts say to select the blocks you want to incorporate, then go to More -> Create Hier. Then a new screen is supposed to appear. However, doing "Create Hier" with any combinations of blocks selected seems to do nothing.
Am I doing something wrong, or is there a problem with my GRC?
It's very simple. You just start with a new flow graph in GRC, and use Pad Sources as input, and Pad Sinks as output.
If you want to let the user configure something, use a Parameter GRC block.
You must set the Generate Options in the Options block to Hier Block, and set a sensible ID there, too – don't stick with top_block, but use something (without spaces or -; it needs to work as a python name) that won't conflict with something else.
Here's an example:
You can then Generate button (or press [F5]), and then, after you've done a rescan of your block library with the refresh button you can find (and use) your new block in the Block Category you specified.
This is the first time I'm encountering GetLayoutObjectAttribute and I am having serious issues with it. My variable $web won't set. I think it's because PD_WebV isn't the right object name to refer to, but I don't know how to find the right object name. I can't find the objects name when I hit Edit Layout, so does anyone know how to find an layout objects name?
Loop
Pause/Resume Script [Duration (seconds): 1]
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
If[$Web="done"]
#execute if statements
After Edit:
After some troubleshooting, I found out that PD_WebV is the right object name to refer and it's refered to correctly, so my new question is why doesn't the script go to the line If[$Web="done"] and how could I fix it? Ss my If statement not evaluating something it should be? Is my $web variable never set to done or is the issue something completely different? Would the problem possibly have to do with my WebDirect sharing settings? Any guidance would help. Thanks.
After, After Edit:
So now that my application is getting past Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")], the variable $web only equals <HTML></HTML>. Does anyone know a way, without using javascript, to test the inside of the html tags?
Also, I printed the bounds of the webViewer PD_WebV that I can't locate on the layout but am referring to in the script. The bounds that are printed are different each time I run the script. Is the usual or unusual? My source is also about:blank so it doesn't look like I'm sourcing from a URL
Is my $web variable never set to done or is the issue something
completely different?
If you're doing:
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
then the only time
$Web="done"
will return true is when the web page loaded into your web viewer contains exactly the string "done" (in practical terms, that's never).
I have already suggested in a comment that you test for:
PatternCount ( $webpage ; "</html>" )
This is assuming you want the subsequent steps to execute only after the page has finished loading. The entire script would look something like this:
Loop
Pause/Resume Script [Duration (seconds): 1]
Set Variable[$Web; Value: GetLayoutObjectAttribute("PD_WebV";"content")]
Exit Loop If [ PatternCount ( $webpage ; "</html>" ) ]
End Loop
# execute statements
You might also want to add a counter to the loop and exit the script after n trials.
Ah, I reread your question.
To set the object name for your webviewer so that the GetLayoutObjectAttribute function works you need to set it in the Name field in the inspector when you have the webviewer selected.
e.g.:
After that your variable should populate.
Be aware
What it will populate with will be all of the html from the browser, i.e. not a boolean true/false liek your conditional suggests.
I'm not sure exactly what you're trying to accomplish, but to be able to determine a result from your web viewer you'll need to either parse the HTML to see if it's content contains what you're looking for or within the code you're setting the webviewer with, fire a javascript function that calls back to the FileMaker file using a FileMaker url.
I am interested in sending an MMS within a private application on the iPhone. A lot of the information I need is proprietary, and therefore I can't find it anywhere. Basically, I'm looking for the proper way to construct a CTMessage and encode it for MMS, and then sending it via one of the overloaded sendMMS functions. Thanks in advance.
For those interested: here is what I managed to dig up (&/OR piece together myself).
For every MMS, a CTMessage is allocated & initialized. addRecipient/setRecipient is called to do just that.
For each data/text section a CTMessagePart is built with its data and corresponding datatype, and then added to the CTMessage's items array. The first item in each MMS items array is always a CTMessagePart containing a SMIL-formatted layout that the recipient interprets to display the message. Each CTMessagePart following the first is in the order that it is referenced from the SMIL data.
Each (unmodifiied) iPhone has an instance of CTMessageCenter running, with the id sharedMessageCenter. Calling sharedMessageCenter's sendMMS, giving the id of the CTMessage you just created will automate the rest of the process. Essentially, the CTMessage is encoded using the CTMmsEncoder into an MMS-PDU hex string. (Not to sure of the correct name for it, hah). Anyways, sharedMessageCenter's send method will then send the (encoded) MMS to your provider's MMSC.
That pretty much sums it up, and should give anyone looking to head down that path a good place to start depending on what they're doing. I can do my best to answer any questions.
