I'm trying to hide the menubar in a C++ application using the windows API. I'm using AppendMenu / RemoveMenu to edit items. But I'm sick of the whole menu based interface and I just want to hide the whole application menubar. How can I do that using the windows API?
Call SetMenu with a NULL HWND parameter, according to the docs.

Created a control using windows API: CreateWindowExW and set it's parent to a panel hwnd
But it seems the control does not handle arrow keys, enter keys and tab keys properly.
Is there any flag on wxwidgets give any control created by CreateWindowExW the same ability like edit controls to capture arrow keys, enter keys and tab keys?
The problem might be due to not using WS_EX_CONTROLPARENT for your control when creating it, this style is needed for the built-in tab navigation to work.
And while I don't think it's going to help with your particular problem, I'd still like to say that embedding a native control in an application using wxWidgets is not quite as simple as just giving it the HWND of an existing control as parent, you may want to look at wxNativeWindow (new in wxWidgets 3.1.0) for how to do it correctly.
Can ListControl be used in a dialog in a Non-MFC project? I am using visual c++ 2010.
The examples I have seen so far uses MFC, so it seems to me that ListControl is part of MFC. The code I am working on is not MFC based, however, Visual Studio still allows adding a ListControl to the dialog in the resource view, and generates rc code for the List Control. So my guess is that I should be able to use it. However, I could not use the standard method found online to add variable to the ListControl and use it.
How can I use the ListControl in this case? e.g. adding a column or write something to a cell? Some code example will certainly help.
The CListCtrl class is an MFC class. It can only be used from within an MFC project.
However, CListCtrl is simply a wrapper around the ListView common control, and a ListView control can be used in any Windows application—no MFC required.
The Resource Editor included with Visual C++ (confusingly) refers to a ListView control as a "List Control". You can insert one on your dialog, and all it will do is insert a ListView control.
If you're using MFC, you can choose to create a member variable corresponding to that control. The type of that member variable will be CListCtrl, because it is encapsulating access to a ListView control on your dialog.
If you are not using MFC, you can still use the ListView control, you'll just have to use the standard SDK mechanisms for accessing and manipulating it. For example, to insert an item into the ListView control on your dialog, you would obtain the control's window handle (GetDlgCtrlID) and send it a LVM_INSERTITEM message. The SDK documentation contains sample code listings, but they are a rather poor way to learn. The best resource for good old Windows SDK programming is still Charles Petzold's Programming Windows.
I am really a beginner with MFC. I just want a few guidelines on how to use a ListCtrl in an SDI application. For example, getting input from the user and displaying it in the listctrl when a button is clicked. Please guide me.
In SDI application I would use CListView-derived class for main view. This class has been designed to be used in SDI/MDI apps and supports standard MFC document-view architecture. The CListView class internally uses CListCtrl, but it does automatic resizing and other handy things, you can also get direct access to embedded list ctrl by calling CListView::GetListCtrl() method that returns CListCtrl*.
I am developing an MFC application, can i use SHAutoComplete with a CEdit control? Also is there any ready made auto complete controls are available? or i need to use write all the code for creating the list box below the edit control as user types in edit control?
Just pass CEdit's m_hwnd member to SHAutoComplete. I don't think that extension warrant another class. The listbox is created by the AutoComplete object created by SHAutoComplete.
SHAutoComplete helps to autocomplete paths (system or URL).
If this is a combo box and you want to use autocomplete for suggesting string contained in the combo, you have to write a code to handle it.
There are samples you can find. One I found (working):

Is is possible to draw controls using Visual C++ designer on the main window, in the same way you can design dialogs? I'd preferably like to be able to design the main window controls this way without using MFC, rather than creating them on WM_CREATE.
EDIT: I don't want a dialog-based app, just to be able to design the main window graphically similar to what can be done using Windows Forms Designer in .NET?
Your options are:
Use MFC and create a main window that has a dialog view (based on the CFormView class).
Use WinForms/.NET
Use Qt.
If you're starting a new project and you want to stick with C++, then I highly recommend Qt. Not only is it an excellent framework, but it's cross-platform so your app could be built on Linux and the Mac.

A Visual C++ plugin is available and you can design your main window visually using a tool called Qt Designer.
I'm not sure if I understand what you want your app to look like. If you want your application to be a dialog, then make it a dialog app.
Just create a new MFC Application, and set it to "Dialog based". Now your application will start at that dialog.
If you want to use a native win32 app, just create the dialog in your InitInstance, using CreateDialog (instead of CreateWindow).
In both cases, you use the resource editor to create the dialog.
