PB 打印 打印预览
PB，全称PowerBuilder，是一种流行的面向对象的编程环境，主要用于开发企业级的应用程序，尤其在数据库应用领域具有广泛的应用。在PB中，打印和打印预览是重要的功能，允许用户在实际打印前查看文档的外观，以确保格式正确无误。
在"PB打印打印预览"这个主题下，我们可以深入探讨以下几个关键知识点：
1. **PowerBuilder的打印功能**：PowerBuilder内置了强大的打印支持，允许开发者使用DataWindow控件或自定义代码来实现打印功能。DataWindow控件是PB中的核心组件，能够展示和操作数据库数据，同时支持打印和预览。
2. **打印预览**：在PB中，打印预览功能允许用户在打印前看到文档的实际打印效果。这有助于检查布局、字体、图像等是否符合预期，避免浪费纸张。预览通常可以在独立的窗口中打开，用户可以缩放、平移和旋转页面以获得全面的视图。
3. **PB125的升级**：PB125指的是PowerBuilder 12.5版本，这是PB的一个更新版本，可能引入了新的特性、性能优化和bug修复。升级到PB125意味着开发者可以利用更现代的功能来增强其打印和预览体验，比如改进的图形渲染和更好的数据处理能力。
4. **PB9到PB125的差异**：从PB9升级到PB125，开发者会遇到一些兼容性问题和新功能的学习曲线。例如，PB125可能支持.NET Framework，提供更好的Windows Aero支持，以及增强了的Unicode和Web服务集成。这些变化可能影响到打印预览的实现方式，尤其是如果之前的应用程序依赖于旧版本的特定特性。
5. **PrintReview**：这个压缩包文件中的"PrintReview"可能是PB的一个示例项目或者库，用于演示或教学如何实现打印预览功能。它可能包含源代码、示例数据和说明文档，帮助开发者理解如何在自己的PB应用中实现类似的功能。
6. **学习与实践**：对于PB开发者来说，理解和掌握PrintReview示例至关重要，因为这意味着可以直接借鉴已有的代码结构，减少从零开始编写打印预览代码的工作量。通过研究这个示例，开发者可以学习如何设置打印设置，如何调用预览模式，以及如何处理用户交互。
7. **调试与优化**：在实际项目中，开发者可能需要根据具体需求对打印预览功能进行调整，比如添加页眉页脚、控制打印区域、处理复杂报表等。PrintReview示例可以作为调试和优化的基础，通过修改代码以满足特定业务场景。
总结起来，PB的打印预览功能是开发过程中的重要一环，通过PB125的升级，开发者可以获得更好的工具来实现这一功能。"PrintReview"示例为学习和实践提供了宝贵的资源，帮助开发者提升工作效率，创建出满足用户需求的高质量应用程序。
