I am writing a program in Think C 3.0 in which I would like to convert
floating point numbers to strings and place them in EditText items in
a dialog box. 

my code looks like this:

{
 .
 .
 .
 .
 Str255     str;
 float 	    Value;
 Handle     myHandle;
 Handle     myBox;
 DialogPtr  theDialog;

 theDialog = GetNewDialog(IdNumber, 0, - 1);

 GetDItem(theDialog, itemnum, &myType, &myHandle, &myBox);
 sprintf(str, "%3.1f", value);
 SetIText(myHandle, str);

 .
 .
 .
}

The result is that garbage is printed in the dialog instead of the
converted string. The above conversion method works fine when I am
displaying floats as strings in windows, but it does not work here.

Any suggestions?
