Sorry, that is my typo here.

The program stops at:

BOOL CMenu::Attach(HMENU hMenu)


POPUP MENU 
BEGIN
    POPUP ""
    BEGIN
        MENUITEM "Edit",                  ID_EDIT
        MENUITEM "Object ...",            ID_OBJECT
        MENUITEM SEPARATOR
        MENUITEM "Text...",               ID_TEXT
    END
END

"hMenu" is NULL. Why "hMenu" is null, I created the menu.

Thanks,

I can not use "LoadMenu" for popupmenu? How can I fix?

CreatePopupMenu has already attached an HMENU handle to your CMenu object. You cannot attach a second menu like this. You can use CreatePopupMenu or LoadMenu but not both of them on the same CMenu object.

I also recommend avoiding the new/delete and just create the object on the stack. There is no reason to thrash the heap.

Something like this:

CMenu pPopupMenu;
if(pPopupMenu.LoadMenu(MAKEINTRESOURCE(YOUR_RESOURCE_ID)))
{
	POINT pt;
	GetCursorPos(&pt);
	HMENU hmenuTrackPopup = GetSubMenu(pPopupMenu.m_hMenu, 0);
	TrackPopupMenu(hmenuTrackPopup, TPM_LEFTALIGN | TPM_LEFTBUTTON, pt.x, pt.y, 0,m_hWnd, NULL); 
}

Hi David

Thank you so much.

I have another question for you. I need to create the menubar and toolbar dynamically.

The Mainframe load the default menu from resource like:

"File  Window  Help"

I want to insert some menu between "File" and "Windows". Could you give some hints?

Best regards,

The index is a zero based array, you would insert a new menu item as follows:

CMenu m;
if(m.LoadMenu(MAKEINTRESOURCE(YOUR_RESOURCE_ID)))
{
	CMenu *pMenu = GetMenu();
	if(NULL != pMenu)
	{
		MENUITEMINFO mii = {0};
		mii.cbSize = sizeof(MENUITEMINFO);
		mii.fMask = MIIM_ID | MIIM_STRING;
		mii.dwTypeData = _T("Inserted Menu");
		mii.wID = YOUR_RESOURCE_ITEM_ID;
		pMenu->InsertMenuItem(1,&mii,TRUE);
	}
}

How to stop popup menu from closing?

How do you stop a popup menu from closing when clicking with mouse button?

What I want to do is to create a CMFCDropDownListBox with check boxes (to create a drop list with check boxes). I've created a derived class of CMFCDropDownListBox and CMFCRibbonComboBox.

CMFCDropDownListBox inherits from CMFCPopupMenu.

I've tried to add PreTranslateMessage to my derived DropDownListBox class, but LBUTTONUP/DOWN messages never happens.

Any tip on how to do this? A CMFCRibbonComboBox with check boxes..

I'm not sure exactly what you're after, but if you look at article: Generic Picker Dropdown Control[^], I imitate a combobox.

You could override the OnKillFocus handler (or remove it), and you'd get a menu-a-like window that doesn't get dismissed.

Or you could go straight with my base CGenericPicker class, and derived your own special drop down.

Good luck,

Iain.

What I'm after it to stop CMFCPopupMenu from getting left button click messages, and handle those messages myself. Smile | :)

I found out how to do it:

Inherit CMFCPopupMenuBar and handle the button clicks there. In my inherited CMFCDropDownListBox I override GetMenuBar and returns an instance of my inherited CMFCPopupMenuBar class.

BN_CLICKED not sent to parent. (Button control)

Re: BN_CLICKED not sent to parent. (Button control)

19-Jul-09 3:57

Hi, in my application I set the parent of a button to a static control. After I set the owner (setowner) to the parent of the static (the main window) in order to process messages sent when clicking on the button. The problem is that the function OnButtonClicked() is never called when I click on the button.
I did the same thing with a list control, but it works with it.
I don't know how to fix this bug. Any Idea?
Thanks

Re: BN_CLICKED not sent to parent. (Button control)

19-Jul-09 8:07

I would suggest making a button a child of a static is a bug in itself, but...

Try using spy++ and seeing where the WM_LBUTTONDOWN / BN_CLICKED message(s) get routed. If they disappear into the static control, try adding the SS_NOTIFY style.

Good luck,

Iain.

Hi, in fact it's due to the splitter class I'm using. CSSplitter which isn't derived from CSplitterWnd but made thanks to a static control. Then I added my button to that control and I had to set the parent to the splitter control. I hadn't really the choice.
I succeeded in solving the bug by adding a message event in MESSAGE_MAP of the class. Then I call SendMessage to call the corresponding function with the parent.
Thanks for your help,

Is there any way to convert resource name to resource id?

19-Jul-09 20:39

That sounds like a perfectly good solution to me!

I can understand wanting to let windows do the heavy lifting, but if it does it "wrong"...

Functions exist, MoveTo(x,y) or LineTo(x,y) to draw or move to coordinate points in MFC. Are there also functions to MoveTo or LineTo in 3D? I.E. MoveTo(x,y,z) or LineTo(x,y,z)? Please let me know. Smile | :)

Nope, you've to use a 3D library, like, for instance OpenGL or Direct3D.

Re: Is there any way to convert resource name to resource id?

Hi
I found a macro "MAKEINTRESOURCE" to convert resource id to resource name. Is there any way to convert resource name to resource id?

Thanks,

MAKEINTRESOURCE

Doesn't really convert anything...IIRC, Windows treats any resource name (i.e. character pointer) with a zero high-order word as an integer rather than a string. That's all.

Basically, a resource can be specified with a name OR an integer id. The only difference (as I said) is whether the high-order word is zero or not.

So conversion of resource name to id is completely meaningless, really.

I suppose something like the code below is the closest you could get

int IsResourceNameInt(LPCTSTR resourceName)
{
   return ((int)resourceName&0xffff) == ((int)resourceName)?(int)resourceName:-1;
}

Controls flickering, (buttons over a static control)

Re: Controls flickering, (buttons over a static control)

18-Jul-09 9:36

Hello,
In my application I have buttons over a static control used to display a background image. The problem is when the window needs to be resized, the controls are not drawn simultaneously, so the controls are flickering. For instance the background image is drawn, and only after controls and it's quite annoying, resulting in a sort of flashing app when resizing.
I tried to use SetRedraw(0) and SetRedraw at the beggining and the end of the function but it doesn't work either.
LockWindowUpdate doesn't work too.

Have you got any solution for that ?

Thanks in advance.
