  1. Set hw=New HtmlWindow

  3. hw.SetGeometry 500,200,300,200
  4. hw.Show
  5. hw.Text="Yes,it's a test!"

不过,好像源文件并没有改变,最好的方式是对codes重构,而后Refresh

可以用Xml组件,修改一次Refresh一次

正好在研究这个,学习下

还是用HTA吧,HTA内置的支持Javascript和VBScript

  1. <Html>
  2. <Head>
  3. <Title>My HTML Application</Title>
  4. <HTA:APPLICATION
  5.   APPLICATIONNAME="My HTML Application"
  6.   ID="MyHTMLApplication"
  7.   VERSION="1.0"/>
  8. </Head>
  9. <Script Language="VBScript">

  66. <Center>
  67. <p id="Folders"></p>
  68. <p>
  69. HTA程序设计</br></br>
  70. 良好滴结合HTML和VBS或JavaScript脚本</br></br>
  71. 也即脱离浏览器的Html可执行程序</br></br>
  72. 可以用这个来做VBS和JS本地脚本的GUI</br></br>
