Can anyone explain why I get a compile error for the following code?

CString CDiagram::GetFormattedMessage()
{
    CString strFormat();
    strFormat = "Warning : %s"
    ...

Answer 1

You declared a function strFormat that returns type CString. Whoops. Google “C++ most vexing parse” for more literature. Correct syntax is

CString strFormat;

Which does explicitly call the default constructor, unlike, say, in Java, where this would just declare a null variable without instantiating it.
