如何避免在更改语言时显示按下的键? [英] How to avoid displaying the key pressed when changing the language?

问题描述

我有一个Windows应用程序，可以用我们选择的任何语言(如印地语，阿拉伯语等)提供输入.

我的问题是在文本框中键入内容时，首先显示我键入的键，然后立即将其转换为我之前选择的语言..

我的要求是在转换成另一种语言之前，不要查看按下的键.

这是使用Pre-Render()事件在类似的Web应用程序中完成的.
但是不知道在Windows应用程序中...有什么建议..

以下是我的代码:

Hi,

I''ve a windows application in which the input can be given in any language we select like hindi, Arabic etc..

My problem is while typing in textbox, at first the key which I type is displayed and immediately it is converted into the language I selected previously..

My requirement is not to view the key I pressed before converting into another language.

This is done in Similar Web application using Pre-Render() event..

But do not know in windows app... any suggestion plz..

Below is my code:

private void txtSchoolName_KeyUp(object sender, KeyEventArgs e)
        {

            string str;
            Class2 cls = new Class2();
            if (_lang == "te")       //te-Telugu language
            {
                str = cls.TeluguText(txtSchoolName.Text);
                txtSchoolName.Text = str;
             txtSchoolName.SelectionStart = txtSchoolName.Text.Length;
            }

预先感谢，

推荐答案

代替KeyUp()，请使用KeyPress()事件来捕获您的键盘按键.然后设置e.Handled = true:

Instead of KeyUp(), use KeyPress() event to capture your keyboard presses. Then set e.Handled = true:

private void txtSchoolName_KeyPress(object sender, KeyEventArgs e)
 {

 string str;
 Class2 cls = new Class2();
 if (_lang == "te") //te-Telugu language
 {
 e.Handled = true;
 str = cls.TeluguText(txtSchoolName.Text);
 txtSchoolName.Text = str;
 txtSchoolName.SelectionStart = txtSchoolName.Text.Length;
 }
