DOCUMENT:Q107465 26-JUL-2001 [visualc] TITLE :FIX: ClassWizard Floating-Point Parsing Errors PRODUCT :Microsoft C Compiler PROD/VER::1.0,1.5,2.0 OPER/SYS: KEYWORDS:kbwizard kbMFC kbVCkbbuglist kbfixlist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual C++, versions 1.0, 1.5 - Microsoft Visual C++, version 2.0 ------------------------------------------------------------------------------- SYMPTOMS ======== ClassWizard cannot parse floating-point numbers written in scientific floating-point notation, such as 1.e+006. If a number formatted in this manner is in the lines of code that ClassWizard must parse, the following error is generated: Parsing error: Expected ")". Input Line: "DDV_MinMaxFloat(pDX, m_Var, 0., 1.e+006);" The follow sequence of steps causes the code generator of ClassWizard to generate floating-point numbers in scientific notation: 1. Add an edit control to a dialog box in App Studio. 2. Add a float or double member variable to class of the previously added edit control. 3. In the range validation fields, add a floating-point number that fits one of the following criteria, for member variable of type float: a. It has seven digits or more to the left of the decimal point. b. It has one or more zeros to the right of the decimal point, between the decimal point and the first nonzero number. Or the range validation fields contain a floating-pointer number that fits one of the following criteria, for a member variable of type double: a. It has 16 digits or more to the left of the decimal point. b. It has one or more zeros to the right of the decimal point, between the decimal point and the first nonzero number. RESOLUTION ========== The only work around is to modify the code by hand and convert it back to the original notation. Be aware, however, that if you edit the variables for that class again, the numbers will be converted back to scientific notation. STATUS ====== Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been corrected in Visual C++ 2.1.
