Hi all,

I have a MFC application, This application has a dialog which contains a
richedit control and an edit control, it likes chat dialog in Yahoo
Messenger. I type unicode string in edit control and I want to display it
in rich edit control after user typing enter key. To display the string in
rich edit control I used ReplaceSel function. After I call this function the
string that displays in rich edit control is not correct.
The chinese and japanese text shows as ????
Please show me how to display correctly this string in rich edit control.

Thank In Advance

1. Which version of Visual Studio are you using?
2. You are successfully able to type Unicode in edit control in the same window, but the problem is only with RichEdit?

I am using Visual Studio. net 2005

Yes I am able to type it in Edit control and the problem is with RichEdit only.

Hmm... I faced this problem with earlier versions of VS. Can't believe they hadn't fixed it even on 2005.

This worked for me: Close the project, create a backup of your .RC file, open the .RC file with notepad and replace all instances of the word RICHEDIT with RICHEDIT20W. Save and close the .RC file.

Now build and run your app and let me know if that worked.

Re: Problem to display an array of ascii caracters in a Textbox

Hi guys,

I want to display the content of an array of type unsigned char which contains ascii caracters in a Windows form textbox. After hours of trying to do this, I am asking for some help. I am using Visual C++ Express 2008.

The array is filled by a function who reads data from the serial port.
I get a pointer to that array of unsigned char from a defined function.

something like this :

unsigned char *RxBuffer; // Filled by a function reading COM port.

I want to Display it in a Textbox, something like this :

textBox1->Text = RxBuffer.ToString();

When I do this, it diyplays the decimal value of my ascii code.

For example if the first ascii code in my array is 0x41, I would like "A" to be displayed in the textbox. But instead it displays "51" which is the decimal value.

Any advice? Thx in advance.

you may try the following code, i am not sure that it works , but i think this is one of the ways to solve ur problem , try it !

CString str;
str.Format("%s %x",str, RxBuffer);

now str contains converted data

i think now you can display str in your text box

Nope. Can you spot the problem in your code?

My code looks like this :

cRxBuff1 is the array which I want to diplay in the textbox.

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
			 
  CUart ComPort;	
  ComPort.InitComPort(0x0F);
  DWORD dwBytesRead1;
  unsigned char cRxBuff1[EVAL_READ_BUFFER_LEN];

  if(ReadFile(ComPort.MyHandleCOM1,cRxBuff1,EVAL_READ_BUFFER_LEN,&dwBytesRead1,NULL))
  {
     if(dwBytesRead1 > 0) // Check any data received from Evaluation Board
     {
	 textBox1->Text= ???;

     }
  }

...
if(dwBytesRead1 > 0) // Check any data received from Evaluation Board
{
  int i;
  Byte b;
  for (i=0; i<dwbytesread;>  {
    b = cRxBuff1[i];
    textBox1->Text += b.ToString("x02");
  }
}
...

Anyway, if you choose the right forum [^] then you'll have the chance of better answers.

Almost there, but it is still not diplaying text.
Like this it diplay the Hexadecimal value. 0x41 when I would like 'A' displayed.
If I change

textBox1->Text += b.ToString("x02");
to
textBox1->Text += b.ToString("s");

I get an unhandled exception error due to invalid format.

Sorry if it is not in the good forum, I thought this was related to Visual C++ problem, because my problem is I am not able to display text in a windows form textbox.
What could be the good forum in your opinion?

Thanks a lot, it is working now.

I was sure to have tried this already.
In fact I tried the following just to test if I can display a caracter
textBox1->Text = (Char) cRxBuff1[0];

How come we can do
textBox1->Text += (Char) cRxBuff1[i];
but not
textBox1->Text = (Char) cRxBuff1[i];

??

Because a string is a sequence of characters.
