Textbox displays end of string 0x00 as box character in Windows XP

Question

When I add string data to a textbox, such as textBox.AppendText("my text"),  it shows the end of string character, 0x00, as a box.  This does not happen under Windows 7 but does in Windows XP. It is very annoying to see the box at the end of every string that is displayed.  How can I prevent it from showing?

Answer 1

Hi Tncoder,

Thank you for posting on this forum.

I didn't repro this scenario by your code. Anyway, I suggest you try to remove the character 0x00 since a string always end by 0x00, you don't need to append it manually. And try again.

Best regards,

I've tried all sorts of ways to fix this and nothing works yet. I've done :

myString.Replace("\0", "");
myTextBox.AppendText("this is more text");
myTextBox.Text.Replace("\0", "")

It doesn't fail if I do: myTextBox.Text = "This is a test".  
This only shows up on any XP machine I try. It doesn't fail on Windows 7.

I found something interesting. If I do myTextBox.Text = myTextBox.Text + "this is more text\n\r"; it works.  However, if I use myTextBox.AppendText("this is more text\n\r"), I get the 0x00 or boxes appended to the string.
