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:

C#

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;
            }

Thanks in advance,
Ravi kamesh..

You do something we have not idea about, and still you are asking what's wrong. How would we know?

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

C#

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;
 }

Start with the basic keypress event handler code:

private void txtSchoolName_KeyPress(object sender, KeyEventArgs e)
{
e.Handled = true;
txtSchoolName.Text = "text";
}

Then add your business logic one line at a time to see where the problem is. Also, you have to disable any other event handlers for txtSchoolName textbox to avoid any confusion when your debugging your code.
