在MFC编程中,虽然系统对用向导生成的文档视图程序提供了打印功能,但如果对自动生成的框架程序不做任何改进,打印出来的文档或图形跟屏幕上的显示就不成比例,而对在基于对话框的应用程序中如何实现打印功能也没有太多的介绍。文章对MFC的打印机制进行了深入的分析,介绍了在文档视图框架下以及在对话框的应用程序中实现打印功能的方法。 相似文献

文档-视图结构是MFC的一大特色,它将数据的管理和显示隔离,具有结构合理、扩充性好等优点,给程序开发者带来很大方便。但文档-视图结构牵扯到许多类,比较复杂。本文较深入地从实用的角度探讨了文档和视图之间的相互作用关系。 相似文献

本文描述了使用Singleton工厂类创建表示数据库视图的数据集(DataSet)对象的一种机制。这里视图代表一个特殊用户角色感兴趣的数据，它包含一些表和SQL语句的集合。每个视图在基于XML的配置文档中表示为一个结点，它的结构用Schema来描述，数据存储在XML文档中。通过基于XPath的查询语句来查找存储在XML文档中视图的结点配置信息，工厂类可以依据配置信息创建数据集。由于可以动态地增加结点，工厂类也具有了在运行时动态扩展的能力。 相似文献

Computer Assisted Learning (CAL) is increasingly being recognised as an effective means of teaching and learning. In Gynaecology, the anatomy and surgical steps in vaginal surgery such as vaginal hysterectomy are confusing due to limited access and restricted view of the operative field. The objective of this pilot project was to develop an interactive CAL program on CD–ROM, combining video, illustrations and three–dimensional images to enhance understanding of vaginal hysterectomy in terms of the anatomy and steps of the surgical procedure.
Macromedia Director was used to develop the program. With Director, it is possible to combine text, graphics, animation, video and sound to create interactive material for the web, presentations or CD–ROMS. The CD–ROM takes you through the individual steps of a vaginal hysterectomy combining video clips with voice–over, illustrations and text. The three-dimensional image was included to enhance understanding of the complex relationships between the uterus, bladder and rectum. There is an interactive self–assessment section with multiple–choice questions and an anatomy self–test. The CD–ROM has been evaluated as an educational tool by 12 undergraduate students and 16 trainees in Gynaecology. Most were satisfied with the program. A need for development of further similar educational software has been identified.
The CD–ROM has identified an innovative and useful approach to teaching operative surgery. The results from the evaluation have been positive in terms of the need for similar programs in future. 相似文献

The goal of the present study was to compare children’s word learning through print text, video, and electronic text in the context of a cross-age peer-learning program implemented in linguistically diverse kindergarten and fourth grade classrooms that included English Learners (ELs) and their non-EL peers. Children were assessed at pre- and post-test on measures of receptive and expressive vocabulary knowledge. Findings showed effects of media type on word learning. Effects differed across grades (i.e., kindergarten and fourth grade, language background (i.e., non-EL and EL), and knowledge types (i.e., receptive and expressive). In kindergarten, results suggest that video may be more helpful than electronic texts for supporting receptive and expressive vocabulary, and video may be more helpful than both print and electronic texts for supporting the expressive vocabulary of ELs. In fourth grade, results suggest that video and electronic texts may be more helpful than print texts for supporting expressive vocabulary for non-ELs but not for ELs. 相似文献

随着直播节目在现代电视节目制作中的比例逐渐增加,对于一个经常从事直播节目的演播室视频系统来说,系统的安全性和稳定性变得尤为重要。因此,系统在最初设计时,除了要十分注意系统设备选配的稳定性外,还要从跳线、切换台、同步信号、字幕、电源等方面综合考虑系统的应急性。 相似文献

Expository text is often neglected in the elementary school curriculum even though most of the reading that children do in school is of that type. Most of the research that demonstrates the importance of text structure in reading comprehension and the benefits that accrue from instruction in text structure deals with children at or above the 4th grade. This research literature, reviewed briefly, provides the basis for the work that is described in this article, which involves younger children. First, a study is presented that demonstrates that children are sensitive to text structure, and therefore would benefit from instruction, as early as 2nd grade. Second, a new instructional program is described that focuses intensively on one specific expository structure, compare and contrast. Finally, the results of a study that evaluates the effects of the program are described. 相似文献

Do classroom exemplars promote the application of principles in teacher education? A comparison of videos,animations, and narratives 总被引：2，自引：1，他引：1

Students learned about teaching principles with a multimedia program that either did not include a classroom exemplar illustrating
how to apply the learned principles to the teaching practice (control group) or included a classroom exemplar in video, animation,
or text format. Across two experiments, video and animation groups reported more favorable attitudes towards learning and
were better able to apply the learned principles than the control group. Text and control groups did not differ in their learning
or attitudes towards learning, suggesting that format is an important factor in determining the effectiveness of classroom
exemplars as pedagogical tools for teacher education. Results encourage the use of visual classroom exemplars to promote the
application of theory into practice. 相似文献

Student teachers have difficulty planning lessons that fully integrate social justice with mathematics/science content. This study was a content analysis of 26 poster presentations of mathematics or science lessons incorporating social justice issues made by student teachers (20F, 6M) at a mid-sized college in central New York State. The presented lessons applied four pedagogical approaches to integration (data collection followed by graphing analysis; discussion of text/video; modeling; library/internet investigation) and addressed three major social justice themes (diversity, system disparities in human communities, and in stewardship of earth). Deeper content knowledge, faculty lesson modeling/reflection and practice delivering lessons are recommended. 相似文献
