Problems about Unicode chatting and input.

[haosura]

I want to ask if we can change all Input Box (chatbox, name box) into basic window Text Box or something already available. Because custom Chat Box conflict with Unicode Inputer.

Example when I want to input "á". The inputer must delete "a" then replace with "á" but current chat box may steal SendMessage or PostMessage of inputer, so it return "aá", for double Unicode like "toán" it's become "toanán". The only way to input Unicode I can use now is copy paste from Notepad. If u can input Unicode, pls suggest for me some inputer working well here pls.

I have solve the problem above, this is new source code for TextBox update. I make a recognize to find which text should be replaced and delete them first. This source is for Vietnamese. If u are using other languages, update the RemoveUnicode() with ur alphabet table.

    public static char RemoveUnicode(char chr)
    {
        string text2 = chr.ToString();

        string[] arr1 = new string[] { "á", "à", "ả", "ã", "ạ", "â", "ấ", "ầ", "ẩ", "ẫ", "ậ", "ă", "ắ", "ằ", "ẳ", "ẵ", "ặ",
    "đ",
    "é","è","ẻ","ẽ","ẹ","ê","ế","ề","ể","ễ","ệ",
    "í","ì","ỉ","ĩ","ị",
    "ó","ò","ỏ","õ","ọ","ô","ố","ồ","ổ","ỗ","ộ","ơ","ớ","ờ","ở","ỡ","ợ",
    "ú","ù","ủ","ũ","ụ","ư","ứ","ừ","ử","ữ","ự",
    "ý","ỳ","ỷ","ỹ","ỵ",};
        string[] arr2 = new string[] { "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a", "a",
    "d",
    "e","e","e","e","e","e","e","e","e","e","e",
    "i","i","i","i","i",
    "o","o","o","o","o","o","o","o","o","o","o","o","o","o","o","o","o",
    "u","u","u","u","u","u","u","u","u","u","u",
    "y","y","y","y","y",};
        for (int i = 0; i < arr1.Length; i++)
        {
            text2 = text2.Replace(arr1[i], arr2[i]);
            text2 = text2.Replace(arr1[i].ToUpper(), arr2[i].ToUpper());
        }

        char res = char.Parse(text2);

        return res;
    }

        InsertText(chr.ToString());
