微信小程序开发优势，小程序定制开发的优势小程序定制开发与其它软件系统开发一样，必须要先对公司的实际需求全面的了解沟通交流，结合公司对小程序目标方向，微信小程序建设规划，小程序的工作流程等方面进行详尽的整理。开发设计也是需要独立租服务器的，用于储放定做的小程序的源代码、数据信息、文本文档，而模板小程序只有一个客户登录后台，统一应用分享服务器，那样，公司的用户管理系统，以及企业用户信息等彻底暴露于模版小程序的开发公司中，这类安全系数是很低的。不论是小程序或是APP开发设计，公司在工程开发设计完成后，公司将会真正的取得开发规划的编码的使用权。阅读详情

Transformer是什么？看完这篇你就醍醐灌顶前言由谷歌团队提出的预训练语言模型BERT近年来正在各大自然语言处理任务中屠榜（话说学者们也挺有意思的，模型名都强行凑个芝麻街的人物名，哈哈哈）。 BERT算法的最重要的部分便是Transformer的概念，它本质上是Transformer的编码器部分。而Transformer是什么呢？transformer是永远的神，自从transformer使用了抛弃rnncnn的纯attention机制之后，各种基于transformer结构的预训练模型都如雨后春笋般雄起，而transformer中最重要就是使用阅读详情

简单的方法是用图片做窗体的背景，然后想办法透明，若做成SKIN的那种随时更改的，很麻烦

CSDN讨论组：wxj_lake(蔚蓝的风)　(2000-12-23 21:50:00) 得50分
这是我前段时间一篇稿子的片断

　　关于用VB制作不规则窗口的文章，在各种杂志、报纸、网站上面也不知提过几回了，我都有点不好意思再谈了。但是我们编程序不仅仅要实现功能，更要寻求最佳的实现方案，本着这样的原则，让我们再来回顾一下这个老命题，也向大家介绍一下我的心得。
　　Windows提供了一个API函数SetWindowRgn，凭着这个函数，我们可以把窗口设置为任意形状。问题在于，我们如何来获取所需的区域形状。一般情况下，我们可以使用CreateEllipticRgn创建椭圆区域，CreateRectRgn创建矩形区域，CreateRoundRectRgn创建圆角矩形区域。（口干，喝一口水，继续……）如果我们需要不规则的形状呢？那就可以使用CreatePolygonRgn。可是这个函数需要的参数之一是包含整个不规则区域轮廓坐标点的数组，对于一个稍微复杂一点的形状就可能需要几百个坐标点，要获取和改动这些坐标点都是相当麻烦的。
有没有更为方便的方法呢？答案是肯定的。（不然我在这儿瞎搞什么？）
　　原理是用一张图片作为窗体的背景，图片中有一种颜色是我们不需要的，称为透明色。然后编程一行行地扫描图片，将透明色的点删去，而把有用的像素点合并成一块区域，如此便得到所需的形状了。
　　但是行扫描的速度奇慢，我最初实现的程序起码用了5分钟才显示出窗体。咎其原因是我们选错了兵刃。一开始我使用GetPixel来获取每一点的颜色，这样每取一个点都需要通过设备上下文hdc从图片中读取信息，这就是造成龟速的罪魁祸首了。
　　正确的方法是使用GetBitmapBits函数。它可以将位图中每一点颜色信息一下子读到一个数组中，以后只要扫描这个数组就行了，这将极大的提高运行速度。

Public Declare Function GetObjectAPI Lib "gdi32" Alias "GetObjectA" (ByVal hObject As Long, ByVal nCount As Long, lpObject As Any) As Long
Public Declare Function DeleteObject Lib "gdi32" (ByVal hObject As Long) As Long
Public Declare Function SetWindowRgn Lib "user32" (ByVal hwnd As Long, ByVal hRgn As Long, ByVal bRedraw As Boolean) As Long
Public Declare Function CreateRectRgn Lib "gdi32" (ByVal X1 As Long, ByVal Y1 As Long, ByVal X2 As Long, ByVal Y2 As Long) As Long
Public Declare Function CombineRgn Lib "gdi32" (ByVal hDestRgn As Long, ByVal hSrcRgn1 As Long, ByVal hSrcRgn2 As Long, ByVal nCombineMode As Long) As Long
Public Const RGN_OR = 2
Public Declare Function GetBitmapBits Lib "gdi32" (ByVal hBitmap As Long, ByVal dwCount As Long, lpBits As Any) As Long
Public Type BITMAP
bmType As Long
bmWidth As Long
bmHeight As Long
bmWidthBytes As Long
bmPlanes As Integer
bmBitsPixel As Integer
bmBits As Long
End Type
Dim bmByte() As Byte

Public Sub SetAutoRgn(hForm As Form, Optional transColor As Byte = vbNull)
Dim X As Long, Y As Long
Dim Rgn1 As Long, Rgn2 As Long
Dim SPos As Long, EPos As Long
Dim bm As BITMAP
Dim hbm As Long
Dim Wid As Long, Hgt As Long

'获取窗体背景图片尺寸
hbm = hForm.Picture
GetObjectAPI hbm, Len(bm), bm
Wid = bm.bmWidth
Hgt = bm.bmHeight

'改变窗体尺寸以符合背景图片大小
hForm.Height = Hgt * Screen.TwipsPerPixelY
hForm.Width = Wid * Screen.TwipsPerPixelX

ReDim bmByte(1 To Wid, 1 To Hgt)
GetBitmapBits hbm, Wid * Hgt, bmByte(1, 1) '获取图像数组

'如果没有传入transColor参数，则用第一个像素作为透明色
If transColor = vbNull Then transColor = bmByte(1, 1)

Rgn1 = CreateRectRgn(0, 0, 0, 0)
For Y = 1 To Hgt '逐行扫描
X = 0
Do
X = X + 1

While (bmByte(X, Y) = transColor) And (X < Wid)
X = X + 1 '跳过是透明色的点
Wend
SPos = X

While (bmByte(X, Y) <> transColor) And (X < Wid)
X = X + 1 '跳过不是透明色的点
Wend
EPos = X - 1

'这一段是合并区域
If SPos <= EPos Then
Rgn2 = CreateRectRgn(SPos - 1, Y - 1, EPos, Y)
CombineRgn Rgn1, Rgn1, Rgn2, RGN_OR
DeleteObject Rgn2
End If
Loop Until X >= Wid
Next Y

SetWindowRgn hForm.hwnd, Rgn1, True '设定窗体形状区域
DeleteObject Rgn1
End Sub

　　以上这一大段程序列出了所有必需的API函数申明。自定义过程SetAutoRgn有两个参数，hForm是将要设置形状的窗体名称，transColor是透明颜色值。关于获取窗体背景图片尺寸的代码，相信各位一看就明白，我不再罗嗦。
　　我想需要解释的是像素格式的概念。大家可能已经注意到程序中二维数组bmByte()的类型是Byte，而在后面的循环体中，我每次取数组的一项就代表一个像素点，这意味着窗体的背景图片只能是8位色深256色的图片（比如GIF格式）。如果是16位色深的图片（JPG格式），那么数组的行宽得翻一倍，并且两个数组项才代表一个像素，要不你就把bmByte()的类型改为Integer。同理，24位色深的像素点要用3个Byte表示，32位的要用4个Byte或者一个Long。transColor的值在不同的像素格式下的值也是不同的。比如在8位情况下，它的取值范围为0-255，代表颜色在图片调色板中的位置。好在程序默认以图片左上角第一个像素为透明色，这样你也就不必深究transColor的具体表示方法了。更为详细的关于像素格式的资料可以在MSDN的光盘中找到，限于篇幅，这里就不展开了。
　　好，理解了程序，我们可以试着来运行一下了，大家可以先看看程序运行的效果（见图二）。在我的古董MMX200上，把图一这样一张图片变成图二那样的窗体，大约耗时0.4秒左右，这么一点延迟应该是可以忍受的。如果你不放心，可以这样来调用以了解精确的运行时间。

Private Sub Form_Load()
Dim t As Single
t = Timer
If Me.Picture <> 0 Then Call SetAutoRgn(Me)
MsgBox Timer - t
End Sub

‘请把这一段代码复制到General部分，调用CreateRegion根据图像产生
‘不规则区域。需要先在DestPictureBox中加载图像，黑色为透明区域。
‘如果需要以其他颜色产生透明区域，请修改If tColour = 0 Then一句；
‘比如要以红色产生透明区域，修改为If tColour = RGB(255, 0, 0) Then
‘要创建不规则形状窗体，把所有的“PictureBox”替换为“Form”即可。
‘对于无法加载图像而有hWnd属性的控件(如TextBox)，可以“借花献佛”，
‘使用SetWindowRgn把由PictureBox创建的区域设置给控件，就可以创造出
‘飞机形的文本框，炸弹形的列表框，随你发挥想象啦……

‘入口：DestPictureBox -- 要设置为不规则形状的图片框

‘这里使用GetPixel代替Point方法，直接调用API函数以加快速度。
