Given the following query
...ANSWER
Answered 2021-May-13 at 06:49Even your brute force approach doesn't work if the submission table has no rows for a particular date.
The standard approach is to use dimension tables to create a template of all the rows you desire, then left join your fact table on to it.
QUESTION
I have 4 buttons that have no direct application to my program. I would like to hide or remove them. I've searched to find out what they are called...they look like navigation, left/right arrows, next/previous. I can't seem to find what they are called. I have looked on the Microsoft site and looking at the CTabView members doesn't seem to jump out and say "hey, these are what you're looking for"....
I'm hoping it is a relatively easy task. Anyone know how to just "turn them off"?
Thanks.
UPDATE:I was able to resolve the C4430 mentioned by moving the new function before the existing in OutputWnd.h and that solved the issue in the output pane area where the arrows are now gone. What I forgot to mention is that I have another mechanism AddView that is creating 2 runtime classes and putting those into a tabbed document view. This time, I've been using GetTabControl() to make it pretty, but this also suffers from the same issue, the scroll arrows are now present.
This is what the code looks like that creates the 2 new tabs:
...ANSWER
Answered 2021-Apr-15 at 22:00There is no public, documented API to hide those navigation buttons. However, digging into the MFC sources finds that:
the arrows are
CMFCTabButton m_btnScrollLeft, m_btnScrollRight, m_btnScrollFirst, m_btnScrollLast;inCMFCTabCtrl;they are created in
CMFCTabCtrl::OnCreatewheneverCMFCTabCtrl::m_bScrollisTRUE;CMFCTabCtrl::m_bScrollis set toTRUEinCMFCTabCtrl::Createif any of the stylesSTYLE_FLAT,STYLE_FLAT_SHARED_HORZ_SCROLL,STYLE_3D_SCROLLED,STYLE_3D_ONENOTE,STYLE_3D_VS2005, orSTYLE_3D_ROUNDED_SCROLLis used.
With that insight, the navigation buttons can be turned off in a couple of ways.
By the book: create the
CMFCTabCtrlwithout any of the styles that enable those buttons, which leaves onlySTYLE_3Davailable. That loses the navigation buttons, indeed, but the styling of the tab control also becomes different, and the tabs themselves display as small rectangles rather than trapezoids.Undocumented: override the
CMFCTabCtrl::m_bScrolland set it toFALSEbefore the tab window gets created. For example, derive a classCMyTabCtrlto clearm_bScroll.

QUESTION
following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.
//.ts file
...ANSWER
Answered 2021-Apr-27 at 16:44You can do it with the $event parameter.
Make sure to compare your values safely.
If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.
You can use the trim function to compare your value safely:
c.state.trim() == val.trim()

QUESTION
I have a problem about drawing a nested pie graph in Matplotlib in Python. I wrote some codes to handle with this process but I have an issue related with design and label
I'd like to draw a kind of this nested pie graph. (from the uppermost layer of the nested to its innermost is SEX, ALIGN with covering their counts)
Here is my dataframe which is shown below.
...ANSWER
Answered 2021-Apr-22 at 21:13You define the function percentage_growth(l) in a way that supposes its argument l to be a list (or some other one-dimensional object). But then (to assign colors) you call this function on dc_df_ALIGN_SEX, which is apparently your DataFrame. So the function (in the first iteration of its loop) tries to evaluate dc_df_ALIGN_SEX[0], which throws the key error, because that is not a proper way to index the DataFrame.
Perhaps you want to do something like percentage_growth(dc_df_ALIGN_SEX['count']) instead?
QUESTION
I need to split the words based on the character '/' and reform the words in this way:
This dataframe contains some kids and their presents for Easter. Some kids have two presents, while some have only one.
...ANSWER
Answered 2021-Apr-02 at 18:16You could use str.split using a regex with expand=True to get your first and second present. Note that this will handle the three cases 'present1/present2', 'coulour present' and 'present'. In the latter two cases the newly created column 'present2' will be None.
To handle the case 'colour present1/present2' you can use str.extract with a regular expression containing permissible colours (see colours_regex below). This is to distinguish colour from presents consisting of two words (e.g 'Barby Doll').
The final step is then to use melt with 'Kids' as an identifier
QUESTION
I am trying to create a registration form with Trailblazer and validation setup using Dry-Validation. I hit a snag which seems to be related to virtual fields. My contract looks like this.
...ANSWER
Answered 2021-Apr-18 at 14:54Yogesh Khater from Trailblazer Zulip Chat was kind enough to point out the error for me.
When we need to define a rule for a virtual field, we need to make sure that the property is required. This is a requirement in the dry-validation library.
The above can be fixed by requiring the property.
QUESTION
I recently coded a neural network based on this online book and Sebastian Lague's brief series on neural networks on youtube. I coded it as faithfully to the original as possible but it didn't end up working. I am trying to solve a simple XOR problem with it but it always seems to give me random but similar values. I even tried copying and pasting the author's code, without changing anything, but it still didn't work.

Answered 2021-Apr-17 at 18:12I seem to have fixed it. I made three main changes:
I switched the a and o in the output layer error calculation which then looked like this:

QUESTION
I am trying to replicate the following stacked bar chart with plotly. I attach one screenshot for every hover text I get when hovering on a bar. As you will see there are 2 issues. First I cannot achieve 3 colors, besides the fact that I create them in the legend and secondly I cannot put First dose as top bar besides the fact that I use factor() based on the levels. Maybe there is an issue with the way I have created my dataset. I have no problem if you have to reform it instead of fix the plotly code to replicate the chart.
ANSWER
Answered 2021-Apr-16 at 21:05There might be a problem with your dataset. The 7.6% of full vaccination is listed under first doese. Therefore your coloring might not work.
Furthermore I transformed the data into a long format for an easy way to create hovertemplates.

Install reform
Make sure you are using Go 1.17+, and Go modules support is enabled. Install or update reform package, reform and reform-db commands with: go get -v gopkg.in/reform.v1/... If you are not using Go modules yet, you can use dep to vendor desired version of reform, and then install commands with: go install -v ./vendor/gopkg.in/reform.v1/... You can also install the latest stable version of reform without using Go modules thanks to gopkg.in redirection, but please note that this will not use the stable versions of the database drivers: env GO111MODULE=off go get -u -v gopkg.in/reform.v1/... Canonical import path is gopkg.in/reform.v1; using github.com/go-reform/reform will not work. See note about versioning and branches below.
Use reform-db command to generate models for your existing database schema. For example: reform-db -db-driver=sqlite3 -db-source=example.sqlite3 init
Update generated models or write your own – struct representing a table or view row. For example, store this in file person.go: //go:generate reform //reform:people type Person struct { ID int32 `reform:"id,pk"` Name string `reform:"name"` Email *string `reform:"email"` CreatedAt time.Time `reform:"created_at"` UpdatedAt *time.Time `reform:"updated_at"` } Magic comment //reform:people links this model to people table or view in SQL database. The first value in field's reform tag is a column name. pk marks primary key. Use value - or omit tag completely to skip a field. Use pointers (recommended) or sql.NullXXX types for nullable fields.
Run reform [package or directory] or go generate [package or file]. This will create person_reform.go in the same package with type PersonTable and methods on Person.
See documentation how to use it. Simple example: // Get *sql.DB as usual. PostgreSQL example: sqlDB, err := sql.Open("postgres", "postgres://127.0.0.1:5432/database") if err != nil { log.Fatal(err) } defer sqlDB.Close() // Use new *log.Logger for logging. logger := log.New(os.Stderr, "SQL: ", log.Flags()) // Create *reform.DB instance with simple logger. // Any Printf-like function (fmt.Printf, log.Printf, testing.T.Logf, etc) can be used with NewPrintfLogger. // Change dialect for other databases. db := reform.NewDB(sqlDB, postgresql.Dialect, reform.NewPrintfLogger(logger.Printf)) // Save record (performs INSERT or UPDATE). person := &Person{ Name: "Alexey Palazhchenko", Email: pointer.ToString("alexey.palazhchenko@gmail.com"), } if err := db.Save(person); err != nil { log.Fatal(err) } // ID is filled by Save. person2, err := db.FindByPrimaryKeyFrom(PersonTable, person.ID) if err != nil { log.Fatal(err) } fmt.Println(person2.(*Person).Name) // Delete record. if err = db.Delete(person); err != nil { log.Fatal(err) } // Find records by IDs. persons, err := db.FindAllFrom(PersonTable, "id", 1, 2) if err != nil { log.Fatal(err) } for _, p := range persons { fmt.Println(p) }
