在窗体中制作三维字体的VB6程序

我们在利用VB6,0开发应用软件的过程中,为了使窗体界面更加生动,其中一项重要的任务就是增加窗体中字体的显示效果。为此我们可将窗体中部分字体制作成三维字体,增强界面的立体感;下文介绍了一种利用VB6．0程序来实现的简易方法。lfor思路与窗体设置要在窗体中显示字体,通常都是采用标签来完成的。为了达到三维字体的显示效果,可以利用一组大d湘同的标签来实现。首先让它们相互重叠,然后使它们按照顺序偏移一定的位移量,通过改变不同方向上的位移量值,就可以制作出不同效果的三维字体。！）设置菌体控件在窗体（Forml）中放置两…

在VB中创建工具栏的方法

<正>1利用图片框(Picture Box)和图像框(Image Box)来生成工具栏①绘制工具栏;在工具箱中双击Pic-ture Box控件或单击该控件后到窗体中拖动鼠标,将Picture 1加入到窗体中,设置Picture1的属性如下:Picture1 Align=1(该属性保证图片框位于窗体的顶端)Width=4800(该属性保证图片框的宽度等于窗体的宽度,这里以窗体的宽度为4800为例来介绍)。Height属性可根据实际情况来设置。这个图片框就是整个工具栏的外框了。②绘制工具栏中的按钮;按钮的绘制有两种方法,一种是用命令按钮控件来绘制;一种是用图像框控件来绘制。下面分别介绍这两种方法。a.用命令按钮控件来绘制:在工具箱中单击命令按钮控件后到窗体中拖动鼠标至合适的大小松开,将一个命令按钮Command1加入到Picture1中,也就是加入到工具栏中了。命令按钮Command1的属性如下:Command1 Caption=打开(该属性是设置工具栏按钮的名称)Style=1(该属性保证工具栏按钮为图片按钮)     

VB．NET中定制不规则窗体

文章介绍的在Visual Basic．Net定制不同规则窗体的实现方法主要使用的是Region类和GraphicsPath类。GraphicsPath类主要是绘制窗体的形状，其提供了丰富的方法，可以实现复杂的窗体形状；Region类主要是以GraphicsPath来构建窗体。以实现各种不规则的窗体。本文通过五种形状的窗体的实现过程，介绍使用Visual Basic．Net创建不规则窗体的方法。     

VB中图片滚动浏览的编程

在昆虫、植物标本等多媒体数据库系统中,通常在窗体上放进标签、文本、图象框等控件,用图象框显示图片。当图片尺寸大于图象框控件尺寸或者大于屏幕桌面时,ＶＢ提供的图象框只能显示图片局部画面,而实际应用中常需要显示浏览整副图片。本文通过给窗体添加滚动条的方法实现滚动浏览大图片的功能。１设计思路、窗体控件及其属性的设置在窗体（ｆｒｍｐｉｃｔｕｒｅ）中放进图象框（Ｐｉｃｔｕｒｅ１）、垂直滚动条（ＶＳｃｒｏＩＩ１）、水平滚动条（ＨＳｃｒｏｌｌ１）、标签（Ｌａｂｅｌｌ）。标签为正方形,做滚动条宽度的基准。垂直滚…

Picture deformation

Algebraic picture generation based on a pixel deformation theory is presented. The main tool used is the deformation monoid which simulates the algebraic structure of pictures viewed as rectangular arrays with operations the horizontal and vertical concatenation. Picture languages generated by grammatical systems are considered and a Chomsky-like normal form as well as an iteration lemma are established. Infinite pictures are obtained as the ω-completion of the set of finite pictures ordered by picture refinement. Regular fractal pictures (such as the Sierpinski Carpet, the Cantor dust, etc.) are defined as the components of the least solution of systems whose right hand side members are finite pictures. They constitute the least class of pictures containing the finite pictures and closed under substitution and the self similarity operation. Solving non deterministic picture program schemes we get the so called ∞-refinement languages which consist of finite and infinite pictures. For such languages the emptiness and finiteness problems are decidable.     

Picture files for hierarchically structured pictures

For a high-level graphics programming language like PASCAL/Graph[1, 2] which allows a hierarchical structure in the representation of pictures, there must exist an appropriate concept for mapping them on sequential files, and vice versa. This paper describes the internal implementation of pictures in PASCAL/Graph by the picture graph. An important feature is the common subpicture, which means picture information can be reused for several higher level pictures without being duplicated. The representation of such pictures on external files, called picture files, is explained, too. Attention is directed to the correct conversion and reconversion between internal and external representation, so that the status of common subpictures is preserved without any exception. This concept allows many effective operations in constructing pictures as well as storing pictures in a very efficient way, both in main memory and on files. The simple GKS metafile cannot handle these complexly structured pictures; therefore, the more complicated form of picture files (metafiles) is necessary.

Geometric pictures for quantum search algorithms

In this paper, we give the geometric pictures for quantum search algorithms in decomposed form, namely in terms of a phase rotation of the marked state and a phase rotation about the average. We apply this formalism to various quantum search algorithms, and give explicit interpretations of the standard Grover algorithm, arbitrary phase rotations, phase matching and fixed-point search algorithm. The pictures straightforwardly show how state vectors evolve during the search process. These results are helpful in understanding how the quantum search algorithms work.     

Characterization of Deadlocks in Irregular Networks

This work characterizes how various network parameters influence message blocking and deadlocks in irregular networks. Information on blocking behavior is provided that is useful in making design trade-offs between restricting routing freedom and allowing the possibility for deadlocks to form in irregular networks. This paper also identifies ways in which a network's susceptibility to deadlock can be reduced and provides guidelines for designing irregular networks that maximize routing flexibility and resource utilization. Finally, a new empirical evaluation methodology for classifying irregular topologies and relating network behavior to various classes of network topologies is introduced.
