the IE-> tool --> Option --> advanced, that is, you do not need to use UTF-8 encoding to send URLs, however, because IE is sent in UTF Encoding by default, everyone needs to change the IE settings.
The general cause of this problem is that IE uses utf8 encoding for the Chinese characters in the URL ---> after the Web server receives the URL, it needs to be decoded. Different web server decoding rules are also different, however, the decoding is gener
You can not only display PNG, JPG, BMP, etc., but only display a single frame.
One way is to use createimagefromfile in iimagingfactory
Let's take a look at msdn:
This method lets an application create a decoded image object from a file.Syntax
HRESULT CreateImageFromFile( const WCHAR* filename, IImage** image);
Parameters
Filename
[In] A wchar array containing the name of the source file.

from the previous introduction that fileencodingIt is automatically set after Vim detects a file when it is opened. Therefore, in case of garbled characters, we cannot correct the garbled characters by setting fileencoding again after opening the file.4 fileencodings
The automatic identification of encoding is implemented by setting fileencodings. Note that it is in the plural form. Fileencodings is a list separated by commas (,). Each item in the list is an encoded name. When we open the file,

Therefore, in case of garbled characters, we cannot correct the garbled characters by setting fileencoding again after opening the file. 4. the automatic identification of fileencodings encoding is implemented by setting fileencodings. Note that it is in the plural form. Fileencodings is a list separated by commas (,). Each item in the list is an encoded name. When we open the file, VIM uses the encod
encoding method that is strictly required and is more prone to decoding failures when the file is not encoded, put the loose encoding method at the end. For example, latin1 is a very loose encoding method. The text obtained by any encoding method is decoded using latin1 and will not fail to be decoded.-Of course, the decoded results are naturally "garbled ". The
step.
1. test.txt saves Chinese Characters in some encoding method, such as UTF-8.
2. bufferedreaderreads the byte content of test.txt directly and constructs the string by default. After analyzing the code of bufferedreader, we can see that bufferedreader calls the read method of filereader, and filereader callsThe native read method of fileinputstream. The so-called native method is the underlying method of the operating system. Therefore, fileinputstream reads files in GBK mode by default.

Next, we will introduce the world's popular Caesar password Caesar cipher, also known as shift password.
Shift the password, that is, the letters in the password will be shifted according to the specified number.
A common case is the ROT13 password, where letters are moved to 13 locations. By 'A'↔'N', 'B'↔'O', and so on.
Write a ROT13 function to encrypt the input string and decrypt the output string.
All letters are in uppercase. Do not convert any non-alphanumeric characters (such as spaces
Python has added support for it. Now you can use JSON for codec.
import json variable = ['hello', 42, [1,'two'],'apple'] print "Original {0} - {1}".format(variable,type(variable)) # encoding encode = json.dumps(variable) print "Encoded {0} - {1}".format(encode,type(encode)) #deccoding decoded = json.loads(encode) print "Decoded {0} - {1}".format(decoded
UISlider, UISlider
// Create UISlider. The height is a value, but cannot be set to 0.
// Slide if the height is 0
UISlider * slider = [[UISlideralloc] initWithFrame: CGRectMake (200, 10)];
// Set the maximum value. Do not set the inverse value. Otherwise, you cannot slide.
Slider. maximumValue = 1;
Slider. minimumValue = 0;
// Set the initial value of the row.
Slider. value =. 5;
// [Slider setValue:. 5 animated: YES];
// Create an image that needs to be displayed on the sliding button

It should be noted that the input of this decoder must contain only the video encoded data "bare stream" (for example, H. T, Hevc Stream file), but not the encapsulated format of the media data (such as AVI, MKV, MP4).The functions of the key functions in the flowchart are listed as follows:

convention is simple:The encoder encodes multiple images into a section of the GOP (Group of Pictures), and the decoder reads a segment of the GOP when it is decoded to decode the screen before rendering the display.The GOP (Group of Pictures) is a contiguous set of images consisting of an I-frame and several b/p frames, which are the basic unit of video image encoder and decoder access, and the order of the sequences will be repeated until the end o

This is a native Python serialization method. In recent years, however, JSON has become popular and Python has added support for it. Now you can use JSON to codec.
Copy Code code as follows:
Import JSON
variable = [' Hello ', +, [1, ' two '], ' Apple ']print ' Original {0}-{1} '. Format (variable,type (variable))
