.NET程序半角变全角解决方法.(.NET2003 .NET2005)
方法一：
将Form的ImeMode属性设置为Hangul即可
方法二：
#region 中文全半角转换
[DllImport("imm32.dll")]
public static extern IntPtr ImmGetContext(IntPtr hwnd);
[DllImport("imm32.dll")]
public static extern bool ImmGetOpenStatus(IntPtr himc);
[DllImport("imm32.dll")]
public static extern bool ImmSetOpenStatus(IntPtr himc, bool b);
[DllImport("imm32.dll")]
public static extern bool ImmGetConversionStatus(IntPtr himc, ref int lpdw, ref int lpdw2);
[DllImport("imm32.dll")]
public static extern int ImmSimulateHotKey(IntPtr hwnd, int lngHotkey);
private const int IME_CMODE_FULLSHAPE = 0x8;
private const int IME_CHOTKEY_SHAPE_TOGGLE = 0x11;
private void ChangeIme()
{
IntPtr HIme = ImmGetContext(this.Handle);
if (ImmGetOpenStatus(HIme)) //如果输入法处于打开状态
{
int iMode = 0;
int iSentence = 0;
bool bSuccess = ImmGetConversionStatus(HIme, ref iMode, ref iSentence); //检索输入法信息
if (bSuccess)
{
if ((iMode & IME_CMODE_FULLSHAPE) > 0) //如果是全角
ImmSimulateHotKey(this.Handle, IME_CHOTKEY_SHAPE_TOGGLE); //转换成半角
}
}
}
private void textBox1_Enter(object sender, EventArgs e)
{
ChangeIme();
}
private void textBox1_Click(object sender, EventArgs e)
{
ChangeIme();
}
#endregion
方法三:
//新建一个类
public class Globe_Cls
{
//**Settle the IME 全角 problem below *************************************
//声明一些API函数
[DllImport("imm32.dll")]
public static extern IntPtr ImmGetContext(IntPtr hwnd);
[DllImport("imm32.dll")]
public static extern bool ImmGetOpenStatus(IntPtr himc);
[DllImport("imm32.dll")]
public static extern bool ImmSetOpenStatus(IntPtr himc, bool b);
[DllImport("imm32.dll")]
public static extern bool ImmGetConversionStatus(IntPtr himc, ref int lpdw, ref int lpdw2);
[DllImport("imm32.dll")]
public static extern int ImmSimulateHotKey(IntPtr hwnd, int lngHotkey);
public const int IME_CMODE_FULLSHAPE = 0x8;
public const int IME_CHOTKEY_SHAPE_TOGGLE = 0x11;
//重载SetIme，传入Form
public static void SetIme(Form frm)
{
frm.Paint += new PaintEventHandler(frm_Paint);
ChangeAllControl(frm);
}
//重载SetIme，传入Control
public static void SetIme(Control ctl)
{
ChangeAllControl(ctl);
}
//重载SetIme，传入对象句柄
public static void SetIme(IntPtr Handel)
{
ChangeControlIme(Handel);
}
private static void ChangeAllControl(Control ctl)
{
//在控件的的Enter事件中触发来调整输入法状态
ctl.Enter += new EventHandler(ctl_Enter);
//遍历子控件，使每个控件都用上Enter的委托处理
foreach (Control ctlChild in ctl.Controls)
ChangeAllControl(ctlChild);
}
static void frm_Paint(object sender, PaintEventArgs e)
{
/*有人问为什么使用Pain事件，而不用Load事件或Activated事件，是基于下列考虑：
* 1、在您的Form中，有些控件可能是运行时动态添加的
* 2、在您的Form中，使用到了非.NET的OCX控件
* 3、Form调用子Form的时候，Activated事件根本不会触发 */
ChangeControlIme(sender);
}
//控件的Enter处理程序
static void ctl_Enter(object sender, EventArgs e)
{
ChangeControlIme(sender);
}
private static void ChangeControlIme(object sender)
{
Control ctl = (Control)sender;
ChangeControlIme(ctl.Handle);
}
//下面这个函数才是真正检查输入法的全角半角状态
private static void ChangeControlIme(IntPtr h)
{
IntPtr HIme = ImmGetContext(h);
if (ImmGetOpenStatus(HIme)) //如果输入法处于打开状态
{
int iMode = 0;
int iSentence = 0;
bool bSuccess = ImmGetConversionStatus(HIme, ref iMode, ref iSentence); //检索输入法信息
if (bSuccess)
{
if ((iMode & IME_CMODE_FULLSHAPE) > 0) //如果是全角
ImmSimulateHotKey(h, IME_CHOTKEY_SHAPE_TOGGLE); //转换成半角
}
}
}
//** the code about IME 全角 problem above *********************************
……
}
//在每个有BUG的窗体的form_load事件中加入
Globe_Cls.SetIme(this);
代码就可以了。
