GeneralBetter error checking using sscanf Pin

So I am trying to take user input from an editbox for my dialog based app. The value should be a single float. I retrieve the value using GetWindowText() and sscanf(). I check that sscanf returns 1 to show that it in fact succesfully scanned in one

CString ValueStr;<br />
float ValueFloat;<br />
<br />
GetDlgItem(IDC_EDITBOX)->GetWindowText(ValueStr);<br />
if (1 == sscanf(ValueStr, "%f", ValueFloat))<br />
{<br />
//valid data, processing it...<br />
}<br />
else<br />
{<br />
MessageBox("Invalid input value.");<br />
}


The problem is that this method of error checking is not the best. For example, if the user enters "20.5p", that will not flag an error, but instead will just take 20.5 as a valid value and ignore "p". How can I do more thorough error checking, such that I check to make sure the input is ONLY a single float and no trailing characters?

Thanks
