Dear Sir

I 'm trying convert c# to vb.net but I have an error : `Error BC30311 Value of type 'Keys' cannot be converted to 'Char'.` in vb.net

Please Guide me.

Thanks

Code in c#

public override bool KeyEntersEditMode(KeyEventArgs e)
{
    NumberFormatInfo numberFormatInfo = System.Globalization.CultureInfo.CurrentCulture.NumberFormat;
    Keys negativeSignKey = Keys.None;
    string negativeSignStr = numberFormatInfo.NegativeSign;
    if (!string.IsNullOrEmpty(negativeSignStr) && negativeSignStr.Length == 1)
    {
        negativeSignKey = (Keys)(VkKeyScan(negativeSignStr[0]));
    }
 
    if ((char.IsDigit((char)e.KeyCode) ||
         (e.KeyCode >= Keys.NumPad0 && e.KeyCode <= Keys.NumPad9) ||
         negativeSignKey == e.KeyCode ||
         Keys.Subtract == e.KeyCode) &&
        !e.Shift && !e.Alt && !e.Control)
    {
        return true;
    }
    return false;
}

Code in vb.net

Public Overrides Function KeyEntersEditMode(ByVal e As KeyEventArgs) As Boolean
    Dim numberFormatInfo As NumberFormatInfo = System.Globalization.CultureInfo.CurrentCulture.NumberFormat
    Dim negativeSignKey As Keys = Keys.None
    Dim negativeSignStr As String = numberFormatInfo.NegativeSign
    If Not String.IsNullOrEmpty(negativeSignStr) AndAlso negativeSignStr.Length = 1 Then
        negativeSignKey = CType(VkKeyScan(negativeSignStr.Chars(0)), Keys)
    End If
    `Error below line code
    If (Char.IsDigit(CChar(e.KeyCode)) OrElse (e.KeyCode >= Keys.NumPad0 AndAlso e.KeyCode <= Keys.NumPad9) OrElse negativeSignKey = e.KeyCode OrElse Keys.Subtract = e.KeyCode) AndAlso Not e.Shift AndAlso Not e.Alt AndAlso Not e.Control Then
        Return True
    End If
