I need to check if a specific region that exists images I want to click, and images will show up randomly, I write the code to check that, however it takes over 10 seconds to check the region, is there anyway I can shorten the time.
Settings.MinSimilarity = 0.95
Reg = Region(582,404,214,187)
img = capture(Reg)
search = True
Settings.MoveMouseDelay = 0
while search :
if Reg.exists("12.png") or Reg.exists("13.png") or Reg.exists("14.png")or Reg.exists("15.png")or Reg.exists("28.png"):
click(Reg.getLastMatch())
search = False
You can add a 0 parameter to the exists() call.
So instead of
if Reg.exists("12.png") or Reg.exists("13.png") or Reg.exists("14.png")or Reg.exists("15.png")or Reg.exists("28.png"):
You would have:
if Reg.exists("12.png",0) or Reg.exists("13.png",0) or Reg.exists("14.png",0)or Reg.exists("15.png",0)or Reg.exists("28.png",0):
According to this, the zero parameter means that
0 as the second parameter to exists forces, that only one search is executed and the result returned immediately. It does not wait the standard 3 seconds, so it is very responsive.
The smaller the region, the faster this will be.
Try this:
Reg.setAutoWaitTimeout(0.5)
This reduce time for detection from 3 secs to 0.5 secs or the value you like.

I am using ag-grid-angular 27.1.1
serverSideStoreType = 'partial'
If i setup paginationAutoPageSize = true and didnt provide paginationPageSize, when the getRows event performed the paginationPageSize is using default value 100 and pagination works only for 100 rows. If i setup paginationAutoPageSize = true and paginationPageSize = 10 the getRows event performed twice on gridReady event and then on every pagination event. If i setup paginationPageSize = 10 works fine but i cant change page size..
How i can implement paginationAutoPageSize or changing page size manually?
I have collection with 10mill rows without any index.In this case system should read whole table ?
When i use eplain statement then it shows
db.employees.find({hundreds2:{$lt:1}},{}).explain();
"nscannedObjects" : 10000000,
"n" : 105
millis" : 6027
It works fine.
But i am using java to process query . Here is code
whereQuery = new BasicDBObject();
whereQuery.put("hundreds2",new BasicDBObject("$lt", rangeQuery));
timer.start();
setupMongoDBReadQuery(arrForRange[posOfArr]);
cursor = coll.find(whereQuery);
timer.stop();
this.selectTime= timer.elapsed();
timer.start();
while (cursor.hasNext())
{
numberOfRows++;
cursor.next();
}
timer.stop();
this.fetchTime= timer.elapsed();
this.totalOfSelAndFetch=this.selectTime+this.fetchTime;
But after test result .I got this information
selTime=2 fetchTime=6350 numRows105 TotalTime6352
selTime=0 fetchTime=6290 numRows471 TotalTime6290
selTime=0 fetchTime=6365 numRows922 TotalTime6365
Why fetch time is more than select .As per my knowledge ,while loop is just printing data . Why it taking so much time to print and how mongoDB select number of rows with 0 or 2 millSec?
Same experiment i did in MySQL with similiar code and results are
selTime=6302 fetchTime=1 numRows105 TotalTime6303
selTime=6318 fetchTime=1 numRows471 TotalTime6319
selTime=6387 fetchTime=2 numRows922 TotalTime6389
MongoDB uses lazy evaluation with cursors. That means in many cases when you start a MongoDB query which returns a cursor, the query doesn't get executed yet.
The actual selection happens when you start requesting data from the cursor.
The main reason is that this allows you to call methods like sort(by), limit(n) or skip(n) on the cursor which can often be processed much more efficiently on the database before selecting any data.
So what you measure with the "fetch time" is actually also part of the selection.
When you want to force the query to execute without fetching any data yet, you could call explain() on the cursor. The database can't measure the execution time without actually performing the query. However, in actual real-world use, I would recommend you to not do this and use cursors the way they were intended.
I already asked a Question Here.
My this question is just a step ahead to same problem.
I have a delphi code which works perfectly for calling report.
But, now I wanted to show a MessageBox before opening rpt file.
I tried to query it separately for record count and then decide for MessageBox. But, this solution is having a worst case where a aprticular report's query itself takes 3 mins to execute and then again querying while opening rpt it takes 30 sec to load (in second query it takes less time may be because of some data may present in buffer/temp place,etc.).
qPODPhy.close;
qPODPhy.SQL.clear;
qPODPhy.SQL.text :='select * from ViewName';
qPODPhy.Open;
If qPODPhy.RecordCount < 1 Then
MessageBOx('No data To Display...');
Else
Begin
crRep.Somproperties := Initialization
.
.
.
CrRep.SQLQuery := qPODPhy.SQL.text;
crRep.action := 1
End
My Question is :
How can I show a MessageBox if no record is going to present for particular view's output.
OR
Is there a method where I can open the dataset of .rpt file in delphi code and just check the count of records and make the decision? In short, is there some property of crystalreport component which can do this?
You can do a select count(*) separately, that is much faster.
Or maybe select only one record: SELECT TOP 1 ....
And, as RBA suggested, you can try putting that SELECT COUNT in a stored procedure for even more speed.
Just experiments with these methods to see if/when you've gained enough speed.
Are you pushing the data ? You can probably use ReadRecords method of the ReportDocument and check Rows.Count property. If the report is retrieving the data the you can use the NoData event of ReportDocument.
When I query some view in Couchbase I get the response that has following structure:
{
"total_rows":100,
"rows":[...]
}
'total_rows' is very useful property that I can use for paging.
But lets say I select only a subset of view using 'start_key' and 'end_key' and of course I don't know how big this subset will be. 'total_rows' is still the same number (as I understand it's just total of whole view). Is there any easy way to know how many rows was selected in subset?
You can use the in-built reduce function _count to get the total count of your query.
Just add _count as reduce function for your view. After that, you will need to make two calls to couchbase:
In one call, you'll set the query param reduce=true (along with either group=true or group_level=n, depending upon how you're sending your key(s)). This will give you the total count of your filtered rows.
In the other call, you'll disable the reduce function with reduce=false because you now need the actual rows.
You can find more details about map and reduce at http://docs.couchbase.com/admin/admin/Views/views-writing.html
You can just use an array count/total/length in whatever language you are using.
For example in PHP:
$result = $cb->view("dev_beer", "beer_by_name", array('startkey' => 'O', 'endkey'=>'P'));
echo "total = >>".count($result["rows"])
If you're actually wanting to paginate your data then you should use limit and skip:
http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-views-writing-querying-pagination.html
If you have to paginate the view in the efficient way, you actually don't need to specify both start and the end.
Generally it is possible to use startkey/startkey_id and limit. In this case the limit will tell you that the page won't be bigger than known size.
Both cases are described in CouchDB book: http://guide.couchdb.org/draft/recipes.html#pagination
Here is how it works:
Request rows_per_page + 1 rows from the view
Display rows_per_page rows, store + 1 row as next_startkey and next_startkey_docid
As page information, keep startkey and next_startkey
Use the next_* values to create the next link, and use the others to create the previous link
My webpage displays realtime data that is updated every 10 seconds from our PI server(historian server). I was recently tasked to take two peices of data that are allready displayed on my page and divide them, displaying the new result on a graph. I have very little experience with AJAX/JQuery, so I was wondering if someone out there can lend me a hand?
Clarification:
Hypethetically-
Say I have "Number of Grades" and "Sum of Grades" displayed on my page as basic integers. They are updated every 10 seconds from the server. I want to take those two pieces of live data, divide them, and display the result (in this case it would be the overall average grade). So, my page will display Number of Grades, Sum of Grades, and Average Grade all updated in real time, every 10 seconds.
I am unclear as to whether JQuery can simply take those values off the server and perform division on them and return a value, or if other steps need to be taken to achieve this. I'm completely shooting in the dark here so sorry in advance for any vagueness or lack of required information.Thank you. Some example code is given below:
<span class = 'PIdata' data-tag = 'NumOfGrades' data-on_pi_change = 'NumOfGradeChange'></span>
<span class = 'PIdata' data-tag = 'SumOfGrades' data-on_pi_change = 'SumOfGradeChange'></span>
I want to display a value that divides NumOfGrades by SumOfGrades.
var sumOfGrades = parseFloat($.('#SumOfGradesId').text());
var numberOfGrades = parseFloat($.('#NumberOfGradesId').text());
var result = fn(sumOfGrades , numberOfGrades);
$.('#AverageGradeId').text(result);
This will set the required value.

The above link seems to have the answer to your question! Basically just access numbers by their id you set, get the value, parse them into integers or floats, perform your calculation, then store the value into the spot you would like it to appear!
