Create Combobox with ToolTips

But you haven't shown yet how exactly it is declared/defined in *your* project ...

Of course I cannot post my code here because my company has rights on it. Anyway the code is more or less this:

CTooltipComboBox *pCombo = (CTooltipComboBox*)GetDlgItem( IDC_... ); // IDC_.... resource index of my combo
for( number of combo items )
{
     pCombo->AddString( combo item name );
     pCombo->SetItemTip( counter, tooltip text );
}

Are you kidding?
Where are the decaration/definition of PreSubclassWindow that "is not automatically called"?

Besides, why are you using GetDlgItem? didn't you implement the control member variable for your combobox?

[symreds]

Declaration/definition of PreSubclassWindow are in CTooltipComboBox.h/.cpp

Anyway, I've always used GetDlgItem instead of a control variable... I think it's the same...

I don't care what you have "lways used".
But my question is: do you only "think it's the same" or you are sure?
And how about the article you referred to:

To use this combo box, follow the following steps:

1. Include TooltipComboBox.h, TooltipComboBox.cpp, TooltipListCtrl.h and TooltipListCtrl.cpp in your project.
2. In the resource editor create a droplist combobox.
3. Create a control member variable for the combobox in VC's classwizard.
4. Include TooltipComboBox.h and replace CComboBox with CTooltipComboBox in your .h file. Also include afxtempl.h to support CMap.
5. To have your own tips, you can either use SetItemTip, SetComboTip functions, or replace GetItemTip function in CTooltipListCtrl, and GetComboTip function in CTooltipComboBox.

Ok, I'm trying to create a control member variable...
I use VS2010 => Class View => I find my dialog class => right click => then? (is this the right procedure?)

MFC Class Wizard
Add Member Variable Wizard

Ok... got it, now the application doesn't crash anymore (and I hit the breakpoint inside PreSubclassWindow()!) but now AddStrings() is no more working: I created an empty combo... I'm going to investigate...

What is AddStrings() and how do you call it?

[symreds]

Sorry, typo error, I mean CComboBox::AddString() (without "s")

[VictorN]

Well, how, when, and where from do you call it?

Post #18 (of course without initial GetDlgItem()...)

That code is into MyDialog::OnInitDialog()

Isn't copy/paste the actual code snippet easier for you than typing in this sentence?

Well, it can be everywhere, but it doesn't help us to see it!
