I have time for example I have in records time written in this way: 00:02:24 or 15:22:45, and now I want to make another column (hours), where can be values for example for time 02:43:22 is value 2, or for time 23:22:14, is value 23 and so on. But I don't know how can I do that, I tried number range, but unsuccessfully.
Here is a picture, how i want to be:
Thanks.
You can use the Modified JavaScript Value step.
I do not know which type is your Time.
If it is a String, a var Hour = Time.substr(0,2); will do.
If it is a Date, use var Hour = Time.getHour();.
If the type is something else, then convert in a String first.
To do this:
drag-and.drop the step Modified JavaScript Valueand link it to the data flow provider (in the example a Data grid).
edit this step and add your script. (Note that you can quickly add the input variable with a double click. Note also that clicking on the Transformation Function in the left menu gives you the list of available function additional to the Javascript built-in collection).
Click on the Get variable button, keep the variable you need (here Hour), and define/redefine its type (here String).
That's done: OK and preview.
If needed, adapt to the type of your input flow. For example Hour = Hour+'' to force a type conversion into a String.

Team,
Occasionally my flow fails and its enough test it manually to running again. However, I want to avoid that this error ocurrs again to stay in calm.
The error that appears is this:
Unable to process template language expressions in action 'Periodo' inputs at line '0' and column '0': 'The template language function 'split' expects its first parameter to be of type string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#split for usage details.'.
And it appears in 2 of the 4 variables that I create:
Client and Periodo
The variable Clientlooks this:
The same scenario to "Periodo".
The variables are build in the same way:
His formula:
trim(first(split(first(skip(split(outputs('Compos'),'client = '),1)),'indicator')))
His formula:
trim(first(split(first(skip(split(outputs('Compos'),'period = '),1)),'DATA_REPORT_DELIVERY')))
The same scenario to the 4 variables. 4 of them strings (numbers).
Also I attached email example where I extract the info:
CO NIV ICE REFRESCOS DE SOYA has finished successfully.CO NIV ICE REFRESCOS DE SOYA
User
binary.struggle#mail.com
Parameters
output = 7
country = 170
period = 202204012
DATA_REPORT_DELIVERY = NO
read_persistance = YES
write_persistance = YES
client = 18277
indicator_group = SALES
Could you give some help? I reach some attepmpts succeded but it fails for no apparent reason:
Thank you.
I'm not sure if you're interested but I'd do it a slightly different way. It's a little more verbose but it will work and it makes your expressions a lot simpler.
I've just taken two of your desired outputs and provided a solution for those, one being client and the other being country. You can apply the other two as need be given it's the same pattern.
If I take client for example, this is the concept.
Initialize Data
This is your string that you provided in your question.
Initialize Split Lines
This will split up your string for each new line. The expression for this step is ...
split(variables('Data'), '\n')
However, you can't just enter that expression into the editor, you need to do it and then edit in in code view and change it from \\n to \n.
Filter For 'client'
This will filter the array created from the split line step and find the item that contains the word client.
`contains(item(), 'client')`
On the other parallel branches, you'd change out the word to whatever you're searching for, e.g. country.
This should give us a single item array with a string.
Initialize 'client'
Finally, we want to extract the value on the right hand side of the equals sign. The expression for this is ...
trim(split(body('Filter_For_''client''')[0], '=')[1])
Again, just change out the body name for the other action in each case.
I need to put body('Filter_For_''client''')[0] and specify the first item in an array because the filter step returns an array. We're going to assume the length is always 1.
Result
You can see from all of that, you have the value as need be. Like I said, it's a little more verbose but (I think) easier to follow and troubleshoot if something goes wrong.
I have a listbox with 2 columns (say "from time" and "to time"). I want to filter user input by 24 hour format only i.e. no other key should be allowed to press except 24 hour time format (i.e 00:00 to 24:00) in the cell. I tried with this: &"0-2"#&"0-3"#:& "0-5"#&"0-9"# it works well but it didn't allow to put something 19:22 or the value after 13:59 in the cell value as I haven't passed other optional value for that 24 hour time format. In regex, it's a bit easy to achieve this ('/^([01][0-9]|2[0-3]):([0-5][0-9])$/') but not sure how this can be done in the 4d database listbox cell field.
Any help would be appreciated. Thanks.
I suggest you make the list box columns text and manage the display and UI yourself if you require fine control over the input values.
The Time string method will convert a time value for you:
$timeStr:=Time string(Current time) // $timeStr = "07:23:45"
The input filters are not RegEx and will not give you the kind of fine control you need. They will let you filter unwanted characters (anything besides numbers for instance). Try this for the Entry Filter on the column
!0&9##:##:##
The result will be a text string of the numbers entered. Write a method to take the input string, parse the elements, validate them, update the data source and then return a properly formatted string for display. I would use the On data change form event as the trigger for running the method.
$h:=Num(Substring($inputStr;1;2))
$m:=Num(Substring($inputStr;3;2))
$s:=Num(Substring($inputStr;5;2))
Recent versions of 4D manage time values as seconds since midnight which is why you may get a longint value instead of a 'time' value sometimes. And depending on which version you are using and the type of listbox (collection, entity selection, array, etc.) you may not even have a 'time' type option for the list box column which can be confusing. Given all that it's just easier to stringify the value and work with that.
For example, what do you want to do if a user enters "33:45:00"? If you want to reject the "33" at the outset you can do this by evaluating each character as it is typed. The On After Keystroke form event lets you run your evaluation method after each change in the field and the Get edited text command allows you to see what the user is entering. https://doc.4d.com/4Dv18R3/4D/18-R3/Get-edited-text.301-4901376.en.html
To convert a string (or longint) into a time value use the Time method:
$timeVar:=Time($timeStr)
4D is a typed language and has had a time type since the beginning. However with the addition of ORDA some UI objects no longer support the time type (collection and entity selection list boxes, for example) and use a longint type instead. This can be confusing if you are working with an existing app or older code but attempting to use the newer tools. Be sure to look over
https://developer.4d.com/docs/en/Concepts/time.html
and
https://doc.4d.com/4Dv18/4D/18/Date-and-Time.201-4504355.en.html
You may not need to get so involved in the input. It depends on the nature of the UI and the data. Time and date is tricky in just about every platform.
I had a scenario like I need to select one random date range from drop down list of values(like today, yesterday, last month etc). How should i select one value randomly every time from the drop down list.waht function or method i need use in my jmeter script.Any one please help me. Thanks in advance
The easiest way to get this done is using HTML Link Parser, refer Poll Example user manual entry for more details, basically you need to provide input name and a wildcard like .* and JMeter will automatically scan the possible options and pick up a random value.
Other option (if the above one is not applicable for some reason) is using XPath Extractor or CSS/JQuery Extractor to get the possible dropdown values from the page DOM, Match No. parameter set to 0 will return the random option value.
I'm stuck on an error in my App Inventor 2 application. I' m using three checkboxes, so the user to pass values to a timer interval in a clock component.
The values are stored in a variable as a list of three values of miliseconds (e.g. 1600, 1800, 2000). I check in code when and which checkbox is checked and then pass it over to a TinyDB database as a tag.
Problem is that, in Do it and on the device running the app, I get the following error as title suggests.
Here is the coding blocks I've used so far:
Does anyone be kind enough to direct me to how solving this error? Is it possible to pass values to a clock component through this logic. I've used a listPicker with success sometime ago, but I need it done with a checkBoxes layout. Thank you all in advance for your answers.
[Edit1]
To overcome this error and before #Taifun's remarks and suggestions, I followed the variable path, to pass values in the timer interval field. Do not now if it is very efficient but it is working for now. Here is the coding blocks:
Bracket pairs like this () represent a list.
The operation TimerInterval cannot accept the arguments: [(1800)]
This is, what the error message is trying to tell you: You are trying to assign a list, which has the item 1800 inside, to the TimerInterval property of a clock component.
You should assign the value directly instead.
Also you should think about the default value: which value should be used, if the user did not store anything in TinyDB... You are currently using an empty string in the valueIfTagNotThere socket... This does not really make sense... A better value would be for example 1000 ... same for the else part in your if-then-else statement...
CodeIgniter stores timezones for its date class in
system/language/english/date_lang.php
I would like to change the strings in this file so that
$lang['UM12'] = '(UTC -12:00) Baker/Howland Island';
$lang['UM11'] = '(UTC -11:00) Samoa Time Zone, Niue';
would instead be
$lang['-12:00'] = '(UTC -12:00) Baker/Howland Island';
$lang['-11:00'] = '(UTC -11:00) Samoa Time Zone, Niue';
Is this possible at all?
Any change I make to the UM__ portion of one line makes it show as a blank on the dropdown. The remaining (unchanged) lines appear OK.
I have also tried to clone this file to application/language/english/ with similar bad results.
Any insights on this?
It looks like this would require hacks to the date_helper.php file which I am not willing to do.
Instead, the date class in CI has the timezones() function which allows you to convert from, for example, UM5 to -5. In that case one can wrap this function around the U__ value coming from the view/dropdown -- and then save it to DB as -5 or some other INT.
Since I want to show the user their selected timezone on that same dropdown, I am forced to have DB fields for the U__ and INT timezone formats. As far as I know, there is no CI function to convert from -5 to UM5.
So, for the user, I pull the U__ format into the view to autopopulate the dropdown.
For timezone conversions and such, I use the INT format.
