ComboBox Help

There is a selected index changed event on the combo box. Handle this event, and then check the text being displayed with GetWindowText(), if it's Test window', then act accordingly. You could also do it by index, if the index won't change, but if it does for some reason, your code will break later.

Thank you for your reply....is it possible if you could give me a step by step, sort of, explination, because I am really lost. Thanks.

1. Add CComboBox m_Combo; to your dialog's header file
2. In the dialog class's DoDataExchange override, add this : DDX_Control(pDX, IDC_COMBO1, m_Combo);
3. Add afx_msg void OnComboChanged(); to your dialog header.
4. In your dialog's BEGIN_MESSAGE_MAP section add the following : ON_CBN_SELCHANGE(IDC_COMBO1, &CDEL_DlgDlg::OnComboChanged)
5. And in OnComboChanged, use the following to get the newly selected item : CString str; m_Combo.GetLBText(m_Combo.GetCurSel(), str);
6. Now, do what you want depending on the selected item.

So, if I understand this correctly, the CString str is the item that is selected in the combobox? Let me know if I am right. Thanks.

Yes. That's correct.

So, I would use a if..else statement for that. For instance if (str=='Test Window\0') { TestWindow wnd; wnd.DoModal(); } Right? I am rather new to working in the Visual Studio. I normally write in Win32 API, or just command line programs. :-) I hope I got this right. ctimko

Yes, CString has an overloaded == operator, so you can do just that.
