vb.net16位色 vbs颜色代码 _Private

vb6.0安装完成后为什么图标没显示出来其实很简单啦。如果你是想用作“编译出来的程序”的图标，你可以先下载一个iconworkshop，打开那个ico，再添加一个16位色和8位色的图标（程序会自动根据32位图标转换）。
然后扔给vb，vb只认16位色和8位色，所以这样的图标就可以使用；编译出来的程序依然会显示原来32位图标。
如何用vb.net向串口发送十六位进制数据下面代码就是将文本框中以一个空格隔开的十六进制转为字节的代码，文本框中数字格式为：01 02 03
Dim TestArray() As String = Split(TextBox1.Text)
Dim hexBytes() As Byte
ReDim hexBytes(TestArray.Length - 1)
Dim i As Integer
For i = 0 To TestArray.Length - 1
hexBytes(i) = Val("h"TestArray(i))
Next
SerialPort.Write(hexBytes, 0, hexBytes.Length)
VB如何获得或设置系统色API 调用 SetSysColors
GetSysColor 获取系统颜色vb.net16位色， SetSysColors 设置系统颜色
Private Const COLOR_BACKGROUND = 1 '桌面背景
Private Const COLOR_ACTIVECAPTION = 2 '活动窗口标题
Private Const COLOR_INACTIVECAPTION = 3 '非活动窗口标题

vb.net 16进制数字转换为字符串把字符串“12341168C5B7”转换为16进制数存为string型
用shuzi=Convert.ToInt32("12341168C5B7",16)
就ok了。
反之用 shuzi.ToString("X")就行了。
给分?。。?
12341168C5B7转换成10进制数就是20014839678391 。。
而int32的最大值为2,147,483,647 。。所以产生错误。
所以要用int64，它的最大值为9,223,372,036,854,775,807 。也就是16位十六进制数0X7FFFFFFFFFFFFFFF 。
难道还有比F靠后的数？？？？？？
