BlackBerry Java program Development, User Agent is required to manually set, so more flexible.
First Use System.getproperty ("Browser.useragent") to obtain the user agent data as follows:
For example: "mozilla/5.0" (BlackBerry; U BlackBerry 9800; EN) applewebkit/534.1+ (khtml, like Gecko) version/6.0.0.246 Mobile safari/534.1+ "
Then use Httpconnection. Setrequestproperty () Sets the user Agent property.

Preface
Since the 1990s S, computer graphics, one of the computer technologies, has developed rapidly. This development benefits from two aspects: first, the faster and faster display chip technology, enabling computers to process more and more complex applications. On the other hand, the excellent graphic applications in turn promote the development of computer display chip technology. In early 8900, The tident TVGA video card was equipped with a K video memory and basically had no running spee

That is, the side length is 512 pixels at maximum. It can be seen that this method is very violent, although it may be faster than reading back the CPU, but the overhead is still very large.Jimenez's MLAAIn the article practical morphological anti-aliasing in GPU Pro 2, a more practical gpu mlaa method named Jimenez's MLAA to differentia

for one dollar each, that is, 10000 yuan.In February 1, the Fund received a dividend of 0.2 yuan for every ten copies, so you got 200 yuan. The total market value of the Fund has not changed before the dividend, so each share is still 1 RMB. However, after the dividend ends, the total market value of the Fund is reduced by two percentage points. As a result, the market value of each fund becomes 0.98 yuan. Therefore, the total value of your fund becomes 980
