Failed To Launch Help Chm

Why do you explicitly call HtmlHelpA rather than just calling HtmlHelp? There does not appear to be an appropriate section in the Wizard to implement Context Sensitive Help like there was in VC++ 6.0. I'll research the ShellExecute or ShellExecuteEx functions further. @anydwestken. Here is the handler code: BOOL CMyDlg::OnHelpInfo(HELPINFO* pHelpInfo) { BOOL bRet = TRUE; if (pHelpInfo->iContextType == HELPINFO_WINDOW) { HWND hwnd = ::HtmlHelp( (HWND)pHelpInfo->hItemHandle, _T("my_chm.chm::/ctrlhlp.txt"), have a peek at this web-site

Hmmm. Why are you doing all that in PreTranslateMessage ?

Are you talking about the MFC Wizard? What gives? Does this mean that context sensitive help is no longer available to applications that are developed? https://community.qlik.com/thread/64693 You’ll be auto redirected in 1 second.

While it works, I still get the nasty message. Is the path to the html help file valid? This one shows the problem more clearly when one tries to summon help using F1 keypress.

All very confusing. Check This Out What the $%^& are Micro$oft up to? It is complicated and difficult to program and creates complicated and error-prone code. The instructions relate the OnHelpInfo handler to a static two-dimensional array and to a .txt file with help text in it.

Seems if you do not install ALL the languages you do not get any help files.So run the QV install and select modify and install the Language Support or uninstall and See msdn's CWinApp::OnHelp for more info.RT Marked as answer by rtischer8277 Wednesday, June 08, 2011 8:08 PM Wednesday, June 08, 2011 8:07 PM Microsoft is conducting an online survey to understand Why does F1 produce 'Failed to launch help' message from my CPropertySheet derived app ?
