I'm using powershell for completing webform. I have dropdown there and can select it by value:
$dropdown.value = '3236'
It works fine, but I need to select by text. I read this answer and tried this code:
($dropdown | where {$_.innerHTML -eq "sometext"}).Selected = $true
It works too, but because dropdown has too many options (probably several thousands), it takes several minutes to select, which is not acceptable.
How can I improve this?
btw, I use powershell 2.0
Okay, I found solution, maybe it isn't perfect, but I got performance improved in hundreds times, instead several minutes it takes less than second.
I created the following function:
function getValue($innerHTML, $Name)
{
$innerHTML = $innerHTML.Substring($innerHTML.IndexOf($Name) - 11, 10)
return $innerHTML.Substring($innerHTML.IndexOf('=') + 1)
}
Function takes innerHTML of dropdown as string, search for option name and return value instead.
and use function the following way:
$drop.Value = getValue $drop.innerHTML 'somename'

I´m quite new to PowerShell and just a bit more experienced with programming as such.
The goal of the current excercise our teacher gave us, is basically to code a simple crossroads traffic light.
I use Windows Forms to display labels, that change colors.
Now I coded a button, that is supposed to run through the traffic light "phases" once.
Thanks to prior experiences I went with the method to have a incrementing variable and a Function that checks the value of said variable.
But the colors turn the intended way once every 4 tries or so, without a recognizable logic to it.
Am I missing something basic in the way PS reads code and the timing thereof?
Button, supposed to reset the variable, then increment it, then call the function. Due to the Write-Host I can at lease say that the variable does count to 4 as intended
$Button1 = New-Object System.Windows.Forms.Button;
$Button1.Location = New-Object System.Drawing.Size(300,100);
$Button1.Text = "Next Phase";
$Window.Controls.Add($Button1);
$Button1.Add_Click({
#Set Phase 0, then increment & update Function Phase
$current_phase = 0;
Do {
$current_phase++;
Write-Host $current_phase;
Phase_update;
} Until($current_phase -gt 3)
Two of the functions minus some of the color changes, intended to change the colors and then wait a while
Function Phase_update
{
#Phase A
if ( $current_phase -eq 1 )
{
$LightTop.ForeColor = 'red';
}
#Phase B
elseif ( $current_phase -eq 2 )
{
$LightTop.ForeColor = 'green'
}
Start-Sleep -Seconds 2
}
# Show Form
[void]$Window.ShowDialog()
Thanks in advance for any input, problem specific and in general
A little background, I'm trying to do a custom Category listing, but at the moment it seems the Category not being sort as I seen on Admin.
Here's the code that I've done so far
$current_store = $this->_storeManager->getStore();
$root_category_id = $this->_storeManager->getStore()->getRootCategoryId();
$collection = $this->_categoryCollectionFactory->create()
->addAttributeToSelect('*')
->addAttributeToFilter('is_active', 1)
->setStore($current_store);
return $collection->addAttributeToFilter('entity_id', array('nin' => $root_category_id))
->setOrder('position','ASC');
And the result, when I tried to echo its ID is like below
3
10
4
11
5
7
12
8
15
9
13
14
16
6
But, from the Admin, it doesn't reflect the order correctly, below is the figure
The problem that I realize is, that, I have sub category, I tried to echo the query from above code, and then copy-paste it into sql GUI, and I realize, the position is kinda weird but, it does make-sense, because it's a sub category.
Here's the result when I execute the query on sql GUI
So, what I tried to achieve is to sort above result, to reflecting what I set on Admin.
Is there anything that I missed? I'm not sure where to look, since I've been stuck around 1-2 days, not sure what's the proper keyword, almost all keyword I did will arrive to product sort or kind of that, not category sort
Thanks in Advance!
For those who still needs some answer relating to this question, here's the answer
...
$store_categories = $this->_categoryFactory->create();
$store_categories = $store_categories->load($this->_root_category_id)->getChildrenCategories();
foreach ($store_categories as $category) {
//get id
$category_id = $category->getId();
//get category model
$category = $this->getCategoryModel($category_id);
$sub_children = $this->getActiveChildCategories($category);
if (count($sub_children) > 0) {
$sub_categories = $this->getSubCategory($sub_children);
$categories = array_merge($categories, $sub_categories);
} else {
$categories[] = $category;
}
}
...
The _categoryFactory comes from Magento\Catalog\Model\CategoryFactory.
It's pretty much covering what I want, but not really as I expected before, because I think it's not really efficient.
PS - I'm still new on Magento 2, so, if someone else has other answer that might be pretty much like I expect, then, I'm happily change it as Accepted Answer. :)
Goodluck!
Is it possible to perform a dynamic "where/filter" in a dataframe ?
I am running a "like" operation to remove items that match specific strings
eventsDF.where(
~eventsDF.myColumn.like('FirstString%') &
~eventsDF.myColumn.like('anotherString%')
).count()
However I need to filter based on strings that come from another dataframe/list.
The solution that I was going for (which doesn't really work) involves a function that receives an index
#my_func[0] = "FirstString"
#my_func[1] = "anotherString"
def my_func(n):
return str(item[n])
newDf.where(
~newDf.useragent.like(str(my_func(1))+'%')
).count()
but I'm struggling to make it work by passing a range (mainly because it's a list instead of an integer)
newDf.where(
~newDf.useragent.like(str(my_func([i for i in range(2)])+'%'))
).count()
I don't want to go down the path of using "exec" or "eval" to perform it
str_likes = [~df.column.like(s) for s in strings] then reduce it into one expression reduce(lambda x, y: x & y, str_likes)
It's a little bit ugly but does what you want. You can also do this in a for loop like so
bool_expr = ~df.column.like(strings[0])
for s in strings[1:]:
bool_expr &= ~df.column.like(s)
df.where(bool_expr).count()
I'm trying to figure out how I can take two date time strings that are stored in our database and convert it to a difference in time format of hh:mm:ss.
I looked at diffForHumans, but that does give the format I'd like and returns things like after, ago, etc; which is useful, but not for what I'm trying to do.
The duration will never span days, only a max of a couple hours.
$startTime = Carbon::parse($this->start_time);
$finishTime = Carbon::parse($this->finish_time);
$totalDuration = $finishTime->diffForHumans($startTime);
dd($totalDuration);
// Have: "21 seconds after"
// Want: 00:00:21
I ended up grabbing the total seconds difference using Carbon:
$totalDuration = $finishTime->diffInSeconds($startTime);
// 21
Then used gmdate:
gmdate('H:i:s', $totalDuration);
// 00:00:21
If anyone has a better way I'd be interested. Otherwise this works.
$finishTime->diff($startTime)->format('%H:%I:%S');
// 00:00:21
$start = new Carbon('2018-10-04 15:00:03');
$end = new Carbon('2018-10-05 17:00:09');
You may use
$start->diff($end)->format('%H:%I:%S');
which gives the difference modulo 24h
02:00:06
If you want to have the difference with more than 24h, you may use :
$start->diffInHours($end) . ':' . $start->diff($end)->format('%I:%S');
which gives :
26:00:06
I know this is an old question, but it still tops Google results when searching for this sort of thing and Carbon has added a lot of flexibility on this, so wanted to drop a 2022 solution here as well.
TL;DR - check out the documentation for different/more verbose versions of the diffForHumans method, and greater control over options.
As an example, we needed to show the difference between two Carbon instances (start and end) in hours & minutes, but it's possible they're more than 24 hours apart—in which case the minutes become less valuable/important. We want to exclude the "ago" or Also wanted to join the strings with a comma.
We can accomplish all of that, with the $options passed into diffForHumans, like this:
use Carbon\CarbonInterface;
$options = [
'join' => ', ',
'parts' => 2,
'syntax' => CarbonInterface::DIFF_ABSOLUTE,
];
return $end->diffForHumans($start, $options);
Which will result in values like what's seen in the Duration column:
Hope that's helpful for someone!
You can do it using the Carbon package this way to get the time difference:
$start_time = new Carbon('14:53:00');
$end_time = new Carbon('15:00:00');
$time_difference_in_minutes = $end_time->diffInMinutes($start_time);//you also find difference in hours using diffInHours()
I have a schema of Row Keys 1-n. In each row there are a variable number of supercolumns with a TimeUUID 'name'. Im hoping to be able to query this data by a time range.
Two issues have come up:
in KeyRange -> the values that I put in for 'start_key' and 'end_key' are getting misunderstood (for lack of a better term) by Thrift. Experimenting with different groups of values Im not seeing what I expect and often get back something completely unexpected.
Example: my row keys are running from 1-1000 with lots of random gaps. I put start_key = 50 and end_key = 20 .. and I get back rows with keys ranging from 99 to 414.
Example: I have a known row with key = 13. Putting this value into start_key and end_key gives me no results.
Second issue: even when I do get results the 'columns' portion of the 'keyslice' is always empty. I have checked via cassandra-cli and I know there is data.
Im using Perl as follows:
my $slice_range = new Cassandra::SliceRange();
$slice_range->{ start } = create_UUID( UUID::Tiny::UUID_TIME, "2010-12-24 00:00:00" );
$slice_range->{ finish } = create_UUID( UUID::Tiny::UUID_TIME, "2011-12-25 00:00:00" );
my $slice_predicate = new Cassandra::SlicePredicate();
$slice_predicate->{ slice_range } = $slice_range;
my $key_range = new Cassandra::KeyRange();
$key_range->{ start_key } = 13;
$key_range->{ end_key } = 13;
my $result = $client->get_range_slices( $column_parent, $slice_predicate, $key_range, $consistency_level );
print Dumper( $result );
Clearly Im misunderstanding some basic precept.
EDIT: It turns out that the Perl library Im using is not properly documented. The UUID creation was not working as advertised. I opened it up, fixed it, and now its all going a bit more as I was expecting. I can slice my supercolumns by date/time range. Still working on getting the key range portion to work.
http://wiki.apache.org/cassandra/FAQ#range_rp covers why you're not seeing what you expect with key ranges.
You need to specify a SlicePredicate that contains the actual range of what you're trying to select. The default of no column_names and no slice_range will result in the empty columns list that you see.
