vb.net text.box 如何实现输入的小写转变为大写

1：将文件拷贝到WORD中

2：点击菜单“格式”——更改大小写，出现对话框

3：可以选择“大写”或者“切换大小写”，就都可以换过来了

最后，再复制回到你所需要的文档中即可！

VB.net做软键盘输入中文汉字,请问在VB.net不是VB6中.怎么做软键盘输入汉字.我现在能输入英文但是汉字不行

既然你可以输入英文，只要系统切换到中文输入方式下，例如“谷歌拼音”，不就可以输入中文了

vb.net的textbox中可以正常输入英文数字切换到中文输入法一按键就退出程序

PrivateSubText1_KeyPress(KeyAsciiAsInteger)If((KeyAscii=48AndKeyAscii=65AndKeyAscii=97AndKeyAscii=122))=FalseThenKeyAscii=0EndSub

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

{

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');

// int t1 = Convert.ToInt32(i1,16);

// int t2 = Convert.ToInt32(i2,16);

int tmp=i1*256+i2;
