SYMPTOMS
========
When attempting to evaluate overloaded functions in Codeview's command window,
you may receive the following error message:
CXX0058: Error: Overloaded Operator Not Found
CAUSE
=====
Codeview's expression evaluator requires exact argument matches in order to
evaluate overloaded functions. In addition, for the purpose of argument
matching, top level modifiers (i.e., const, volatile) are ignored.
RESOLUTION
==========
Use appropriate type casts when specifying function parameters so that they
exactly match the function's formal parameter list. See the next section for
more details.
MORE INFORMATION
================
To demonstrate this problem, build a debug version of the HELLO sample in the
\msvc\mfc\samples\hello directory. Start a debugging session using Codeview for
Windows and enter the following commands in the command window:
>p2
>?afxDump << "Hello\n"
>g CMainWindow::OnAbout
>p2
>?afxDump << about
Both afxDump calls will return the CXX0058 error. The g instruction tells
Codeview to go until it reaches the CMainWindow::OnAbout() function.
Restart HELLO and enter the following commands using the appropriate type casts
(these will evaluate correctly):
p2
?afxDump << (char far *)"Hello\n"
g CMainWindow::OnAbout
p2
?afxDump << (CObject *)&about
