VB.NET 打包安装到目标机后为何没有了声音?
在目标机器上查看一下winmm.dll是否正确注册，如果没问题，那就是对方声卡的问题，再换台机器试试。
Vb（或者VB.net)影像识别系统
建议用VC做吧，VB图像处理速度慢。
VC的话其实不怎么难，简单学学图像处理，网上现成的程序一把，涉及降噪、图像二值化、边界提取、中心计算等问题，还有回调函数也用的到。
如何用vb.net将汉字转换成拼音阿
public string hz2py(string hz) //获得汉字的区位码
{
byte[] sarr = System.Text.Encoding.Default.GetBytes(hz);
int len = sarr.Length;
if (len1)
{
byte[] array = new byte[2];
array = System.Text.Encoding.Default.GetBytes(hz);
int i1 = (short)(array[0] - '\0');
int i2 = (short)(array[1] - '\0');
//unicode解码方式下的汉字码
// array = System.Text.Encoding.Unicode.GetBytes(hz);
// int i1 = (short)(array[0] - '\0');
// int i2 = (short)(array[1] - '\0');
