Binary data in rich text box

[janatech]

Hi All,

I have some binary data to display in a rich text box. It is possible to display the data using

this->textbox1->text = HeadertoDisplayString;

I need to format the data while displaying in the rich text box. So I make a string of data using the data.ToString(" 00 ") and then append to the header using

Line1> this->textbox1->text = this->textbox1->text + data;
Line2> this->textbox1->Update;
Line3> this->form1->Update;

Now when I tried to display as little as 1 MB in size, it takes a very long time to update.
It doesn't make a difference with Line2 & Line3. I am using a reasonably faster system. So there is something wrong with the way the data is being displayed.

What is the best method to display the string faster. Is there any other method? Pls help.

Thank you very much in advance.

Best Regards
Jana

Yes, that is "normal" behavior when you have strings that long.

One approach would be to create a custom control that displays only a portion of the string, and "moves" up and down the total string as you use the scroll bars.
