Due to the needs of a customer friend, need my WinForm development framework to support the operation of the national Dream database, this database has been heard very early, but the real general project with very little, generally in some special projects may need to use. Since my WinForm development framework is based on the implementation of the data access layer of Enterprise Library, it is easy to add support

Make your PHP support GIF, png, and JPEG at the same timeAfter RedHat6.2 is compiled and installed by php manual, it is found that only GIF images can be processed and JPEG images cannot be processed. Later, I learned that PHP used the GD library to process images, and the GD library started to support GIF. However, because GIF uses the copyrighted LZW algorithm, it may cause legal problems, so from the beg
JSON string, such as:
1
{ foo : ‘bar‘ }
If the JSONP format is agreed with the server, the server will handle the callback parameters and return the results for processing, such as:
1
mycallback({ foo : ‘bar‘ })
As you can see, this is actually a function call, such as the implementation of a callback function named Mycallback in the page definition:
1234
mycallback = function(data){alert(data.foo);};

The single-minimum-support algorithm and multi-minimum-support algorithm can be considered as a special case of the Multi-minimum-support algorithm. In practical applications, the use frequency of the Multi-minimum support algorithm is relati
First: trend analysis."Price changes with a certain trend" is one of the three assumptions of technical analysis. It can be seen that trend analysis in technical analysis is very important. The main trends are rising and falling. Trend line is one of the methods for judging a trend. In the rising market, when the price falls to the rising trend line, it will usually turn to the upward rebound, because the essence of the rising trend line is an important supp
