PHP scenario, you need to convert the array to a JSON string, you need to use PHP's own json_encode function;But when the array contains Chinese strings, the result of the transfer is the following:1PHP2 3 $TMPARR=Array(4' Name ' = ' trousers ',5' Color ' = ' blue ',6' Size ' = ' XL ',7' title ' and ' Aged mens trousers '8 );9 Ten $tmpJson= Json_encode ($TMPARR); One A Echo $tmpJson;Output: {"name": "\u957f\u88e4", "Color": "Blue", "S
statement is actually a subquery. To demonstrate the use of subqueries in the WHERE clause, assume that you need to display a Sales.SalesOrderDetail record that contains the purchase of a oversized long sleeve logo sweatshirt. The code in Listing 3 satisfies my display requirements by using subqueries. SELECT * FROM [Sales]. [SalesOrderDetail] WHERE ProductID = (SELECT ProductID from [Production]. [Product] WHERE Name = ' Long-sleeve Logo Jersey, XL
resources. Combined with textureloader, you can easily load the texture of an external model.
4. External Model
Alternativa3d supports loading and parsing external models. The supported model file formats include:
*. Dae,
*. A3d,
*. 3DS.
*. Dae is an XML-based Collada model file. *. a3d is a specialized alternativa3d model file, and *. 3Ds is the format used by 3DS

The goal of this tutorial are to create instances of objects instead of copies to improve loading time in games developed u Sing the Ogre3d Graphics Engine in combination with a so-called dotsceneloader. A dotsceneloader is a library that loads a '. Scene ' file generated by OgreMax exporter. OgreMax exporter is used to

Throughout the process I will explain how to create a 3D model and then give it a neon-like glow wi
Anycad. Net/c++ SDK supports a variety of 3d/2d file formats, such as Brep, STEP, IGES, STL, DXF, 3DS, OBJ, FBX, SKP, IFC, DAE ... And so on, depending on the use of the scene to provide different APIs.1. Geometric data I/OSupports Brep, IGES, STEP, and STL formats, where BREP supports reading and saving string streams.1.1. Reading filesSupports reading of Brep, IGES, step, and STL, with results stored in toposhape.Step File Read Example:
Next we will use Mesh to read. X file, about. there are actually a lot of X Files. We can use external tools such as 3DS MAX to create them. 3ds file, and then convert. X file. If you use 3DS at the same time, you may ask, what should we do with the material? You don't have to worry, The. X file can automatically contain materials, and animations, so we can use M
Next we want to use mesh to read. x files, about. x files, in fact, can be said a lot, we can use external tools such as 3DS Max to build a. 3ds file, and then use the tools provided to us by Microsoft to convert to. x Files, if you also use 3DS you may ask, what about the material? You don't have to worry about that. X files can automatically contain materials,
Python xlrd, a common method for reading excel, pythonxlrd
I watched a video on excel operations by the old K. I am very grateful to the old K for sharing it!
To install the xlrd module, open cmd and enter the command: pip install xlrd to install it. If it has been installed, it is shown as follows:
You can use the following methods to read excel files from xlrd:
''' 1. open the file ''' xl = xlrd. open_workbook (file) ''' 2. Obtain sheet ''' prin

length is (n-k) the interval to find the difference between the maximum and the minimum difference (= =), and then da lei to find the smallest.Since we can prove that the optimal sequence after the deletion of the element is sequential, it must be sequential, so only the enumeration is required. (Proof slightly)But at the end of the interval the minimum difference is to use the multiplier St algorithm, otherwise it will time out ...The code is as follows (style ugly don't mind)#include #include

Line Segments and Windows: medium to large at the left endpoint ≤ small at the right endpoint

Excel files, the basic method is to use component multiplexing technology to invoke the COM service components provided by the Office software platform, taking advantage of the methods provided by COM components to manipulate Excel files. The application example in this article is a simple demonstration of how COM technology can be used to output data from a dataset dataset to an Excel file. The implementation process and the main source code are as follows: Create a new window class Tfrmcomexc
