            react-native-maps custom map style
            Asked 2022-Mar-23 at 17:44

            I created a json using google maps styling wizard. I then set that to a const under render and set that const to my MapView style but it renderers nothing when I do.

            I am not sure the issue, Ideally I would like to have the style in a separate file but I was trying to start small.

            How can I fix the current issue I am having as well as import and use the style from a separate file?

            Here is a snack of my code that reproduces my exact error as well as the code below.



            Answered 2022-Mar-23 at 17:44

            The custom google maps styling must be passed to the customMapStyle prop and you need to set a specific width and height in the normal style prop of the MapView. Setting absoluteFillObject does something different than you might have thought and according to the react-native documentation there is

            Currently, there is no difference between using absoluteFill vs. absoluteFillObject.

            Thus, absoluteFill is for the following use case.

            A very common pattern is to create overlays with position absolute and zero positioning (position: 'absolute', left: 0, right: 0, top: 0, bottom: 0), so absoluteFill can be used for convenience and to reduce duplication of these repeated styles.

            This will not set a height and a width! We need to do this manually which is documented here.

            The following solves your problem.

            Cell style is lost or not displayed in Excel 97-2003 (.xls)
            Asked 2022-Mar-11 at 06:49

            I am using the Apache POI library to export data to Excel. I have tried all the latest versions (3.17, 4.1.2, and 5.2.1).

            I have a problem with Excel 97 (.xls) format in relation to cell styles. The cell style somehow is lost (or not displayed) after a certain number of columns.

            Here is my sample code:



            Answered 2022-Mar-11 at 06:49

            Creating cell styles for each single cell is not a good idea using apache poi. Cell styles are stored on workbook level in Excel. The sheets and cells share the cell styles if possible.

            And there are limits for maximum count of different cell styles in all Excel versions. The limit for the binary *.xls is less than the one for the OOXML *.xlsx.

            The limit alone cannot be the only reason for the result you have. But it seems as if Excel is not very happy with the 50 exactly same cell styles in workbook. Those are memory waste as only one shared style would be necessary as all the 50 cells share the same style.

            Solutions are:

            Do creating the cell styles on workbook level outside cell creating loops and only set the styles to the cells in the loop.

            Update content of references to text mark in DOCX
            Asked 2022-Mar-04 at 09:55

            My need in short: I want to refresh references to text marks in a docx document with Apache POI 5.

            Context: In a docx document, my system replaces text in placeholders (e.g. "${myplaceholder}"). Some of these placeholders are within text marks. This works fine.

            In the document there are references to the text marks. After replacing placeholders (within the text mark), I open the docx document, select everything with Ctrl+A and hit F9. Then all references are updated and contain the text from the referenced text marks / placeholders.

            Problem/Quest: I do not want (the system users) to hit Ctrl+A / F9 to update the references.

            Question: Is there a way either (a) to force Microsoft Word to refresh all references (like this is feasible for xlsx files with Apache POI) or (b) to refresh all references in Apache POI 5?

            Update + simple code example:

            This is the content of the input docx document (where the second "${firstname}" is a reference to the first "${firstname}" (marked in MS Word as a text mark)):

            This is some code that adds some text to the "firstname" placeholder:



            Answered 2022-Mar-04 at 09:55

            The whole problem goes away when the text-replacement works correctly.

            The problem here is how Word stores texts in different text runs. Not only different formatting splits text in different text runs, also marking grammar and spelling check problems do and multiple other things. So one can impossible predict how a text gets split into text runs when typed in Word. That's why your text-replacement approach is not good.

            Apache POI provides TextSegment to solve those kind of problems. And using current apache poi 5.2.0 this also seems to work correctly. Former versions had have bugs in XWPFParagraph.searchText - see Apache POI: ${my_placeholder} is treated as three different runs for a workaround.

            Using TextSegment one can determine the begin and end of a seached text and so doing the text-replacement better.

            Following example should show this.

            My Reference.docx looks like so:

            There ${firstname}, ${lastname} and ${address} in head are bookmarked as firstname. lastname and address. And their occurences in text are references as { REF firstname } , { REF lastname} and { REF address}

            Apache POI docx file content control parse

            I'm trying to parse docx file that contains content control fields (that are added using window like this, reference image, mine is on another language)

            I'm using library APACHE POI. I found this question on how to do it. I used the same code:



            Answered 2022-Feb-28 at 12:11

            According to your uploaded sample files your content controls are in a table. The code you had found only gets content controls from document body directly.

            Tables are beastly things in Word as table cells may contain whole document bodies each. That's why content controls in table cells are strictly separated from content controls in main document body. Their ooxml class is CTSdtCell instead of CTSdtRun or CTSdtBlock and in apache poi their class is XWPFSDTCell instead of XWPFSDT.

            If it is only about reading the content, then one could fall back to XWPFAbstractSDT which is the abstract parent class of XWPFSDTCell as well as of XWPFSDT. So following code should work:

            How to handle user-defined data structure in Fortran90?
            Asked 2022-Feb-24 at 15:55

            in my program I defined a data type called Lyapunov_orbit that contains 8 fields, then I used it to read data from external .txt file (see below where I report only a few lines for convenience because the file has about 4000 lines). I need to perform some operations by using such structure (as to find minimum and maximum value of an array) but to handle it I had to declare an "auxiliary" variable called vec_J_cst because if I try to directly use my data strucutre, I get some errors (the structure-name is invalid or missing).

            Merge documents by inserting content into a new page using poi
            Asked 2022-Jan-13 at 17:14

            I have several documents and I want to combine them all into one docx file. My code :



            Answered 2022-Jan-13 at 17:14

            Your code only appends multiple CTBody elements into the document. But that is not how a Word document is structured. "It works" because Microsoft Word is tolerant enough to interpret it. But it fails when it comes to references within the Word document structure.

            For example to numbering definitions are referenced by IDs. And that can be the same ID for different definitions in different documents. So ID 1 in first document might be pointing to a decimal numbering while ID 1 in second document might be pointing to a bullet numbering. So the numIDs needs to be merged and not only copied.

            Embedded media (images for ex.) are referenced by rIDs. So the CTBody only contains the IDs. The media itself is stored outside the document body. So if the document body refers to a picture having rID12 and this picture is not stored, then the document gets corrupted.

            Same is with many other document elements.

            So that approach is not usable at all.

            The need is traversing all body elements of the document, which shall be appended. Then append each found body element to the first document and update it's references.

            The following is a working draft to show the principle. It is not ready yet. For example it does not considering hyperlinks, footnotes, comments, structured document tags and much more things. And as you see from the sheer amount of code needed, considering all possible things will be a very laborious task to do. To avoid even more code I simply copy the underlying XML bean if possible. This also should be better formed out for productive usage. But the principle should be clear from this code.

            The code is commented when names of methods and variables are not self explained.

            The code is tested and works using current apache poi 5.1.0. Former versions are not tested and also should not be used since they offer even less support for XWPF.

            The code needs the full jar of all of the schemas as mentioned in Apache POI FAQ.

            Is it possible to increase de accracy / precision of the Geocoder JSON response?

            I could accomplish it using the Map, however, with the Geocoder It wasn't possible.

            Problem Description

            Answered 2022-Jan-09 at 06:11

            Precision of 6 decimal places gives you ~10 centimeter accuracy. Mapbox is using GeoJSON specification which has following recommendation about precision:

            The size of a GeoJSON text in bytes is a major interoperability consideration, and precision of coordinate values has a large impact on the size of texts. A GeoJSON text containing many detailed Polygons can be inflated almost by a factor of two by increasing coordinate precision from 6 to 15 decimal places. For geographic coordinates with units of degrees, 6 decimal places (a default common in, e.g., sprintf) amounts to about 10 centimeters, a precision well within that of current GPS systems. Implementations should consider the cost of using a greater precision than necessary.

            GPS-enabled smartphones are typically accurate to within a 4.9 m (16 ft.) radius under open sky. However, their accuracy worsens near buildings, bridges, and trees.ref

There is however a constructor for such document that takes a Stream argument on construction.
