Failed to launch help

[Carneno]

Hello,

I'm working with a Visual Studio 2015 C++ program converted from a VS 6.0 C++ program.

When I run the program and select "Help" from the menus, it gives this messagebox: https://drive.google.com/open?id=0B3Jw7h2K4ZvkcHdXbTRMYjMwTWc

I can't find the text "Failed to launch help" anywhere in the solution.

I can't figure out where in the program, the code gets executed when the menu option is selected. I put breakpoints in the code that has "menu" or "help" in the coding, but it never stops on any of them.

I found this code in the program, but it never stops in the debugger when I set a breakpoint on it:

void CMagicApp::WinHelp(DWORD dwData, UINT nCmd)
{
#ifdef USE_HTML_HELP
	if (dwData>HID_BASE_RESOURCE && nCmd == 1)
	{
		::HtmlHelp(AfxGetMainWnd()->m_hWnd, GetHelpFilePath(), HH_HELP_CONTEXT, dwData/*-HID_BASE_RESOURCE*/);
	}
	else if (nCmd == 3)
		::HtmlHelp(AfxGetMainWnd()->m_hWnd, GetHelpFilePath(), HH_DISPLAY_TOC, 0);

	/*
	else if (dwData>HID_BASE_COMMAND && nCmd == 1)
	HtmlHelp(AfxGetMainWnd()->m_hWnd, GetHelpFilePath(),
	HH_HELP_CONTEXT, dwData-HID_BASE_RESOURCE);
	*/
#else
	CWinApp::WinHelp(dwData, nCmd);
#endif
}

The help menu option works in VS 6.0 version.

Any help that anyone can provide to fix this problem would be gratefully appreciated.

Thanks,
Tony

Did you define USE_HTML_HELP ?

I'm sorry Thomas.

I didn't know that you had asked this question until today. I can't find the option for these forums to be notified when someone replies to my posts.

I fixed this problem by removing this line: ON_COMMAND(ID_HELP, CFrameWnd::OnHelp) from the message map in the class that inherits public CFramweWnd.

Added this line: ON_COMMAND(ID_HELP, CMagicApp::OnHelp) to the message map in the class that inherits public CWinApp.

Added this code to the .cpp file for the class that inherits public CWinApp:

void CMagicApp::OnHelp() //Modified by Tony Girgenti - added these lines
{
	//CWinApp::OnHelp();
	CMagicApp::WinHelp(HID_BASE_RESOURCE + IDR_MAINFRAME);
	
}

Thanks,
Tony
