I have a CXTPControlComboBox on my ribbon, if the user enters an invalid value then I wish to display a balloon tip telling them the problem.

I have tried the following, but the balloon tip is not displayed:

NMXTPCONTROL* tagNMCONTROL = (NMXTPCONTROL*)pNMHDR;
CXTPControlComboBox* pControl = (CXTPControlComboBox*)tagNMCONTROL->pControl;
........
if(bError == true)
pControl->GetEditCtrl()->ShowBalloonTip(L"Error", L"Description", TTI_ERROR);

Hi,

Edit part of ComboBox is actually RichEdit. Seems Microsoft didn't implement EM_SHOWBALLOONTIP for RichEdit :(

Just like I mentioned before; it is absolutely crucial that you let the programmer choose between Edit and RichEdit! I've pinpointed other problems too. Such as ES_PASSWORD, ES_NUMBER...

I hope you make this configurable in 13.1.

I agree with znakeeye, it would be good if it was CEdit instead of richedit, then the balloon tips would work, which are very useful, and also allow easily to limit the user to numbers and such without having to drastically override the classes and do it all manually.

Guess I'll have to try and find a long way round to solving the problem of notifying the user of a problem.

Hi,

It can be configured with custom Edit. See CControlComboBoxEditEx from Samples\CommandBars\CustomThemes\CustomControls.cpp.

override edit and add

BOOL CMyCommandBarEditCtrl::CreateEdit(DWORD dwStyle, CWnd* pParentWnd)
{
return CEdit::Create(dwStyle, CRect(0, 0, 0, 0), pParentWnd, 0);
}

I can live with that, but please make sure to add ASSERTs for incompatible EDIT-styles!

Looked at the sample. I'm confused. From which class should you derive CMyCommandBarEditCtrl?
