在计算机网络通讯各种服务中,文件传输应该算是最基本、最简单的功能服务了。较早之前,程序员一般通过C语言等高级语言编写大量复杂的程序代码,以实现计算机之间的文件传输。随着信息产业的不断发展,人们开发出了许多可视化的、面向对象的编程工具(如Delphi、VC、VB、PB等),由现在的事件触发程序代替了原来的顺序执行的程序结构,程序员现在只需通过点击鼠标编写少量程序代码,即能实现原先较复杂的程序功能,这大大加快了程序的开发速度,也大大降低了程序员开发程序的难度。  相似文献

基于ole技术调用EXCEL实现复杂报表生成   总被引:1,自引:0,他引:1  
PB(PowerBuilder)是Sybase公司推出的一款优秀的数据库开发工具,以其功能强大、简单易学而闻名于世,但其报表功能却相对缺乏,尤其是制作中国式报表。通过PB的ole技术,实现在Power Builder中调用Excel来实现复杂报袁的生成与打印。  相似文献

PowerPoint和Flash是目前最常用的课件制作工具,两者各有优缺点:PowerPoint易学易用、操作简单,有丰富的特效及页面过渡效果,但课件必需在PowcrPoint下才能使用,网络功能差,且容易被盗用;Flash的动画功能(特别是交互式动画)强大,开发出来的课件体积小,保护措施完善,但文字、图像处理没有PowerPoint方便,比较难学,特别是动作脚本(ActionScript)更是让初学者生畏。如果能把PowerPoint和Flash结合,使其优势互补,所开发的课件会更精美。下面就是具体的操作过程:  相似文献

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.  相似文献

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.  相似文献

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?  相似文献

Different nations have different social cultures, and the social culture of every nation is developing with the development of the nation, language is greatly influenced by social culture, which enables language to possess national and historical characteristics. Word is the smallest, independent, meaningful linguistic unit of language. It can well reflect the national and historical characteristics. From synchronic aspect, the social and cultural influence on word meaning is mainly embodied in conceptual and associative meanings of word. The incorrespondence of word meaning is a phenomenon that exists in both conceptual and associative meanings of word among different languages. From diachronic aspect, the development of social culture causes some changes of word meaning to some extent. Therefore, social culture plays a key role in vocabulary learning and mastery of a language.  相似文献

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.  相似文献
