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 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. 
|
|
|
|
|
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.

Glad you've solved your own problem - always the best learning experience that way!

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

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,

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.

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

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,
|
|
|

transoft wrote: 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;
}

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.

Did you try "CMemDC" class?
|
|
|
|
|
I use a library for the gui that I can't modify, so I can't use CmemDC. (dskinlite)

Hi Netc. How about making the buttons child controls of your static and give the static control the style WS_CLIPCHILDREN, would that work? For more background see KB79981[^].

Do not use CSocket, consider using CAsyncSocket if it has to be MFC based. Also see CSocket considered harmful[^] in the Winsock Programmer's FAQ.

Hi Guys,
This same problem has driven me nuts but finally i fixed it and it is working. This is bug with MFC socket library that when inside a thread [other than main application thread], If we try to do something like
CSocket socket;<br />
socket.Create();
It will throws an unhandled exception. I found an article on it See What Microsoft says about this
that said something from Microsoft but that did not help me either. So here is a workaround i have found and i hope it can help some frustrated fellow like me.
Inside thread, do this
CSocket mySock;<br />
SOCKET sockethandle = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);<br />
mySock.m_hSocket= sockethandle;
After that DO NOT call mySock.Create as it has been created already through assignment of socket handle. I am not sure if we can use mySock.Attach(sockethandle) as i did not try it yet.
After that you can call Connect etc directly.
When you are done using the socket, DO NOT call
<code></code>mySock.Close() - rather call
closesocket(mySock.m_hSocket); And that will free the socket object. If Attach works in above case then i guess we need to do Detach here when to free the socket.
Good Luck

Question: Whenever an object is created, memory will be allocated for the data "int a;".
Will a destructor, with an empty body, deallocate the memory taken for the object when the object goes out of scope??
Is it our job to include the memory deallocation functions inside the destructor body?

Any destructor will call the destructor of any child object when it completes.
It will not (and cannot) deallocate the memory taken by the object. What if the object's on the stack? No deallocation needed!
If you want to automatically handle object memory management, use smart[^] pointers[^].
