1.VB 关于系统托盘显示数字

VB 关于系统托盘显示数字

       把数字0-9做成.

       0-9的源码直接显,或用拉伸(难看点)

       >的用隐藏的控件拼合所需再另存成图(抓图代码)调用.

       一个导向,明白了就行

       select Case的确是不够意思......:)

       ------------------------------------

       -3-3

       合成嘛,还是不给代码:P

       你会在image中画东西吧?在界面上输出文字做个什么定位的没问题吧?,让他们重叠没问题吧? 屏幕截图会不会?(CaptureWindow函数以及CreateBitmapPicture函数,ExtractIcon函数).

       ----------------------

       下面转一段截图文章

       ---------------------

       大家知道在VB下利用API函数Bitblt可以将屏幕或者窗口上的图象拷贝到VB中的PictureBox对象中,但是如果简单的利用PictureBox的SavePicture函数来保存图象,会发现什么也保存不了。源码这篇文章就是源码介绍如何捕获并利用Windows下的OLE API函数保存图象。

        首先来看源程序,源码技能特效源码首先建立一个新的源码工程文件,然后在Form1中加入5个CommandButton对象和一个PictureBox对象,源码源码的拼音然后在Form1中加入以下代码:

       End Sub

        运行程序,点击command1或者Command2就可以捕捉成个屏幕或者窗口到Picture1中,源码然后点击Command4或者Command5就可以保存或打印图象。源码

        上面的源码程序中最重要的是CaptureWindow函数以及CreateBitmapPicture函数,CaptureWindow函数建立与要捕捉的源码窗口的绘图设备(Device Context)句柄相兼容的绘图设备(Device Context)句柄,然后建立相应的源码调色板,最后将绘图设备(Device Context)中的源码加载框架源码图象拷贝到一个hBitmap对象句柄中。CreateBitmapPicture函数则根据传递过来的源码hBitmap对象句柄和调色板句柄建立一个Picture对象。在将这个对象赋予PictureBox的源码Picture属性,然后就可以使用SavePicture函数来保存图象了。仿dilidili源码

        OleCreatePictureIndirect函数支持的不仅有BMP图象,同时也支持Ico图标,所以利用该函数和ExtractIcon函数也可以提取并保存Windows文件中的spring 获取源码图标。有兴趣的读者可以到我的主页/~blackcat上下载源程序。
