SYMPTOMS
When attempting to evaluate overloaded functions in Codeview's command window, you may receive the following error message:
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
