So I have a simple app that uses QML for my graphical interface and c++ code for some of the logic. I was looking for a method to compile the QML into c++ code and link it into my binary and found this page over at the Qt home site: Basically it says use the resource system for all of my QML graphical interface files and add the QML compiler flag to my qmake config line in my .pro file and everything should be good to go. As far as I know everything compiles fine, but when I use the the Qt windeployqt.exe tool to get all of the dependency files and test it on a clean system, I get a small white screen as if my QML files were not loaded properly. I have one c++ reference to my main QML file using "qrc:/mainqml.qml" and that's it. Any idea what I am doing wrong? You're using the open source version of Qt. It didn't come with the Qt Quick compiler until Qt 5.11 where it is included - and after a rework, too. So it performs better than precompiled QML did in Qt 5.10 a...

I noticed jackson turns LocalDate s to [2018,06,01] which sucks I can annotate a specific variable/method for it to be properly formatted like so: Which is fine but I have several LocalDate s in my class, I'd rather have a single class level annotation, so: Is there an annotation I can use on my class to format them automatically?

I want to reorder a sheet in excel using an internal SQL query. I have 3 sections of data, say A2:D10, A:11:D20, A21:D30. and I want to order them such that A21:D30 goes first in my spreadsheet.

I know this has been asked before, but I need a little more help than the other answers on SO provide. I currently have a foreach loop that iterates over records in my DB. Each row contains a unique "id" primary attribute (1,2,3,4,5,etc.). In my loop, I need to generate a UNIQUE RGB value for each record based on its ID. The resulting RGB value will be applied to the HTML element's text bound to that record. The generated color must be unique to the record itself (via "id"), which is why I am not using the loop iterator. I have already created a working function to do this for me, but I need one more thing - I need the rgb value to have a contrast ratio greater than 4:5:1 on a white background. The function I have generates colors that are too bright, making the text hard to read. How can I modify my function to produce darker colors that contrast well on a white background? Maybe this isnt possible... but I'm hoping one of you Math geniuses can help me out ...

I am not an expert in MySQL . I need to find out rank of customers. Here I am adding the corresponding ANSI standard SQL query for my requirement. Please help me to convert it to MySQL . Is there any function to find out rank in MySQL? One option is to use a ranking variable, such as the following: The (SELECT @curRank := 0) part allows the variable initialization without requiring a separate SET command. Test case: Result: Here is a generic solution that sorts a table based on a column and assigns rank; rows with ties are assigned same rank (uses an extra variable for this purpose): Note that there are two assignment statements in the second WHEN clause. Sample data: Output: SQL Fiddle While the most upvoted answer ranks, it doesn't partition, You can do a self Join to get the whole thing partitioned also: Use Case Answer : A tweak of Daniel's version to calculate percentile along with rank. Also two people with same marks will get the same rank. Results of the query for a...

I am wondering if it is somehow possible to assign aliases/nicknames/common names to columns which have technical names rather than "easy to read"-names. Say I have a table, where the columnnames are something like "CD12xxx" and I want to translate that into something readable: Can this only be achieved by creating a view and "renaming" all columns with something like [CD12001] AS Customer_ID - or is there a nice way of doing this? In Teradata I have seen something similar at some point, just wondering if it is possible in SQL-Server? I believe it is SQL-Server 2016 my company is running. Thanks.

I have simple Dockerfile And in my entrypoint I'm setting up some configurational keys and set some data to redis via node: Image builds succesfully, but when I running it - nothing happens. What's the problem? What should I do to run redis in container and make some configuration after? May be the trouble is in that I'm running redis as daemon? Answer from author TL:DR There is a pretty similiar question in Stackoverflow which help to fix my problem: The problem was in that a Docker ENTRYPOINT or CMD should "spawn single process". And I put Redis starting and node init.js execution as different programs into supervisord . Providing supervisord.conf for example: Why did I do that? The main trouble which I have with this issue was with misunderstanding what actually is a Docker container. And what does ENTRYPOINT or CMD in Docker.

I am pasting below output of my head command of a BSE stock data column which I use for R programming practice. I googled and tried almost every trick but I am not able to clear white spaces at the end of these values. It seems that all the strings have fixed width of 12 and after characters I see white space which I am unable to remove. not sure if this will paste in exact same way(e.g. i see a lot of white space after word HDFC in its double quotes) but no technique helped me get rid of those trailing whitespaces.

I've been working with Airflow for a while now, which was set up by a colleague. Lately I run into several errors, which require me to more in dept know how to fix certain things within Airflow. I do understand what the 3 processes are, I just don't understand the underlying things that happen when I run them. What exactly happens when I run one of the commands? Can I somewhere see afterwards that they are running? And if I run one of these commands, does this overwrite older webservers/schedulers/workers or add a new one? Moreover, if I for example run airflow webserver , the screen shows some of the things that are happening. Can I simply get out of this by pressing CTRL + C? Because when I do this, it says things like Worker exiting and Shutting down: Master . Does this mean I'm shutting everything down? How else should I get out of the webserver screen then?

I am trying to understand why running a count on my MongoDB view takes so long to perform, and if there are things I can do to speed it up. It looks like this: I am passing filter params in as the param "search" within find() , and then running the count . The target collection of this view has about a half million docs, though the view matches to only about 8,000 of those. In the view I am matching on an indexed field from the targeted collection in stage 1 of my aggregation pipeline - that's what takes me down to 8,000 or so documents. Now, because the count on the much larger target collection uses meta data, it comes back really quickly - in about 240ms. But the count on the view takes over 6 seconds to return, on, as I say, a much smaller data set. Even with the find(search) segment taken out, it still takes over 6 seconds for the count to complete. By the way, I also tried: ... with the same result. And according to the docs, db.orders.count() is equivalent to db...

The following (admittedly contrived) C program fails to compile: When compiling the above C source file with gcc (or Microsoft's CL.EXE), I get the following error: Such simple and intuitive syntax is certainly useful, so this seems like it should be legal, but clearly it is not. Surely I am not the only person frustrated with this apparently silly limitation. I don't understand why this is disallowed-- what problem is the C language trying to avoid by making this useful syntax illegal? It seems like it may have something to do with the way a compiler generates the assembly code for the initialization, because if you remove the "static" keyword (such that the variable "x" is on the stack), then it compiles fine. However, another strange thing is that it compiles fine in C++ (even with the static keyword), but not in C. So, the C++ compiler seems capable of generating the necessary assembly code to perform such an initialization. Edit: Credit to Davislor--...

How do I create an HTML table with fixed/frozen left column and scrollable body? I need a simple solution. I know it's similar to some other questions, like: But I need just a single left column to be frozen and I would prefer a simple and script-less solution. If you want a table where only the columns scroll horizontally, you can position: absolute the first column (and specify its width explicitly), and then wrap the entire table in an overflow-x: scroll block. Don't bother trying this in IE7, however... Relevant HTML & CSS: Fiddle This is an interesting jQuery plugin that creates fixed headers and/or columns . Toggle fixed column to be true on the demo page to see it in action. In case of fixed width left column the best solution is provided by Eamon Nerbonne.

BUT I want to be able to send a message to clients, from outside the Hub. Where some event happens in my application, and a message is sent to clients. In full .NET, I'd use the GlobalHost and get the context. In ALL my searches on Stack Overflow, they reference something that no longer works, or used within an REST API controller that's passed in the IHubContext. I have an event listener in my program.cs, and when the event...

I have simple 2D game on Unity3D. In Unity it's okay, but then I start it on smartphone, I have non-smooth motion and freezes.

Try this: or Think about the contract for Comparator. It returns an int, not boolean. Generally in your @Override implementation of the compare() function, you will want something that returns -1, 0, or 1 (generally an int). So, in this case you would want something like this: This will order Person a1 and Person a2 based on age. Depending on the order you want (ascending vs descending) you can do the comparison as a2.GetAge()...

Is there a way to concat rows if there are duplicate IDs? For example If I were to GROUP BY ROOM_ID I would lose the information in Line 2. So is there a way to get the following results: Thanks If you have only a handful of lines, then conditional aggregation might be the easiest method: Note that this does not generalize very well, but it works quite effectively for two or three addresses.

I have been using these lines in my projects but i do not know what does it exactly means, can anyone please tell me what does it mean exactly. That declares myObject on the global scope. If it was existing before it takes the existing value, or if it is not existing it assigns it to a new empty object (Read on). This is a common technique if multiple scripts assign properties of the same object, so that it doesn't matter which script got executed first they will always end up with the same result. Thats an IIFE were the context gets myObject , that allows you to write to the object easily with The IIFE also makes sure that your variables that you declared inside the function, e.g.: are not part of the global scope, so they are not polluting the global namespace. Notice that inside the IIFE you can access myObject as you wish. See in the below snippet how the printed object is the one created with a key custom and a value associated value . ...

I'm not sure if there should be a loop for this or what the easiest approach would be. My data consists of a list of people participating in our program. They have various start and end dates, but the following equation is able to capture the number of people who participated on a specific date: Is there a way I can loop in different date values to get the number of program participants each day for an entire year? Multiple years? One simple way is to use a CTE to generate the dates and then a left join to bring in the data. For instance, the following gets the counts as of the first of the month for this year: Note that this will work best for a handful of dates. If you want more than 100, you need to add option (maxrecursion 0) to the end of the query. Also, count(people) is highly suspicious. Perhaps you mean sum(people) or something similar.

I'm trying to add new elements to an Array but it keeps overwriting it the first element, i'm not sure if i'm doing it correctly, but this is my code: push method is ok for you. It will add elements at the end of the array. If you have data already setted in your array, then remove this.nArray = because this is creating a new empty array, deleting all previous data stored in nArray variable. In any case, if you want to add elements at the beginning try unshift : this.nArray.unshift(this.data); . If you push data inside nArray you will get an array of array of objects. Maybe you are looking to add only the elements in data and not the whole array. Use concat method for that. this.nArray.push(this.nArray.concat(data)); Or a shorten syntax using spread operator ... : this.nArray.push(...data); NOTE : I'd recommend you to use const for your array definition and remove the blank assignment of in nArray . Also, instead of using concat , use the spread operators wit...

We believe that Stack Overflow should not just be a resource for very specific technical questions, but also for general guidelines on how to solve variations on common problems. "Form based authentication for websites" should be a fine topic for such an experiment. Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question.
