GetDlgItemText(...) crashes on a space.

**Lithorien** · 03-31-2005

In the interests of berevity, I'm only posting the code inside of the case: break;.

Code:

case ID_HTML_HEAD:
{
	int length = GetWindowTextLength(GetDlgItem(hWnd, ID_EDIT));
					
	if (length > 0)
	{
		char *temp = new char;
		
		GetDlgItemText(hWnd, ID_EDIT, temp, length+1);
		
		std::string s(temp);
	
		s += "/* Long string */";
							
	    SetDlgItemText(hWnd, ID_EDIT, s.c_str());
	    
	    delete temp;
	}
	
	else
	{
		SetDlgItemText(hWnd, ID_EDIT, "/* Long string */");
	}
}
break;

The problem is that when I have text in my edit control with a newline (\r\n as Windows defines it), the program exits. I can't figure out how to handle this.

For example, you have text like:

<html>
<head>
<title>Blah</title>
</head>
<body>

Blah.

Thank you in advance.

Code:

char *temp = new char;

I think what you intended was this

Code:

char *temp = new char [length+1];

You do realize you are making space for just one char right?
