一.定义 定义时注意:xml元素是区分大小写的. <web-app></web-app> 这些必须小写 二.url-pattern 1)url-pattern 的值必须以/或者*.开头 <servlet> <servlet-name>TestName</servlet-name> <servlet-class>sedion.jeffli.servlet.AServlet</servlet-class> </servl…

Everyone wants to be successful. Today I would like to share three simple key points of success. Number one is: Know what you are doing. Number two is: Love what you are doing.Number three is: Believe what you are doing. If you follow these three key…

TreeView keep selected node highlighted public QualityCheck() { InitializeComponent(); //trvIndexName.HideSelection = false; //trvIndexName.SelectedNode.BackColor = Color.BlueViolet; // cause DLL problem trvIndexName.DrawMode = TreeViewDrawMode.Owner…

In a typical multiple-tier implementation, the steps for creating and refreshing a DataSet, and in turn, updating the original data are to: Build and fill each DataTable in a DataSet with data from a data source using a DataAdapter. Change the data i…

1.  Uniform 1.1.  Uniform变量 不是所有的变量都是跟顶点一一对应的,如变换矩阵,光源位置等. Uniform变量可以在任何类型的shader中使用,但只能作为输入值,不能在shader中给它赋值,只能在C/C++程序中指定. layout (location = 0) in vec3 VertexPosition; layout (location = 1) in vec3 VertexColor; out vec3 Color; uniform mat4 Rotatio…

1.  Shader起步 1.1.  可编程管线 仅考虑Vertex shader和fragment shader: 1.2.  Shader Object 在编译阶段生成,把shader源代码编译成Shader 对象. Shader对象分类 Vertex Shader Fragment Shader Geometry Shader Tess EvaluationShader Tess ControlShader API: glCreateShader glCompileShader glDel…

Shader和Program Program Link过后,Shader就可以从Program中Detach并删掉.这样是不是可以节省一点点显存呢? 链接到同一个program的vertex和fragment shader,如果有相同名字的uniform,那么uniform的地址是共享的,即是一个uniform. glBufferData和glBufferSubData的区别 glBufferData会重新分配内存 glBufferSubData不分配内存,覆盖以有的内存. GL_STATIC_…

一.配置jsp页面 [jsp-config]中有两个子元素[taglib][jsp-property-group],注意,前者必须出现在后者之前. ①[taglib]替代jsp页面中taglib指令 <jsp-config> <taglib> <taglib-uri>/taglibtest</taglib-uri> <taglib-location>/WEB-INF/tlds/test-tags.tld</taglib-location&g…

@1: Q: What does ROA look like?Since ROA means which ASes are allowed for originating routes to some specific address spaces. So I think there maybe many ASes corresponding to a specific address space. A: No, actually the format of ROA is like this:…
