Does anyone know if it is possible to change the icons on the MFC VSListBox Dialog Control?
Specifically I'm trying to change the folder icon to a '+' icon instead:
I haven't tried it myself, but CVSListBoxBase::AddButton() seems to be what you need.
CVSListBox derives from CVSListBoxBase, and when you call CVSListBoxBase::SetStandardButtons to set the buttons, it calls AddButton() for each button.
The documentation for CVSListBoxBase is unfinished, so you'll have to "play" with it, but you can read the code in afxvslistbox.cpp/.h

I have an dialog with several buttons and sliders on it and am adding another button that should close the dialog and open another that is essentially a mini version it.
I need access to the buttons in the first dialog in the second mini dialog (since they should have the same functionality).
Is there a way to use the class from the first dialog on the second so that I have access to those buttons? I've tried right clicking the dialog and adding a class, but it makes me make a new one instead of being able to use an existing one.
Thanks in advance!
I have a design like below:
So basically, I want to embed three dialogs in the application main dialog and switch between them, for each button click i.e., button 1 will show dialog one , button 2 will hide dialog 1 and show dialog 2 .. and so on.
Each dialog will be having a different design and functions.
I tried using CPropertySheet class to Add pages but its GUI is different. It has either option for navigating the dialogs using next / back button , or from a tab control.
None of which is as per my requirement.
So I want to know is it possible to have a design like this in MFC ? If yes how? Which Class/ control should I use.
Any help will be appreciated.
What you can do is use a normal CDialog class, add your buttons to it and also create a frame/rect as a placeholder for where your embedded dialogs are to appear. The following piece of code will create and position your embedded dialog.
CRect rect;
CWnd *pHost = GetDlgItem(ID_OF_YOUR_FRAME_RECT);
pHost->GetWindowRect(&rect);
ScreenToClient(&rect);
pDialog->Create(ID_OF_YOUR_DIALOG, this);
pDialog->MoveWindow(&rect);
pDialog->ShowWindow(SW_SHOW);
On button clicks, you hide the previously shown dialog (SW_HIDE) and show your selected dialog(SW_SHOW) with ShowWindow(...).
If you create your embedded dialogs with IDD_FORMVIEW style in the add resource editor it'll have the proper styles for embedding.
Another option is probably to use an embedded PropertySheet and hide the tab row and programatically change the tabs on the button clicks. I just find it to be too much fuzz with borders, positioning, validation and such for my liking.
If you have the MFC Feature Pack, that first came with VS2008 SP1 and is in all later versions, you might like to consider CMFCPropertySheet. There are a number of examples on the linked page, that are very similar to your design.
For example, this:
What worked for me just using dialog based application is SetParent() method. Dont know why nobody mentioned it. It seems to work fine.
I am doing like below:
VERIFY(pDlg1.Create(PanelDlg::IDD, this));
VERIFY(pDlg2.Create(PanelDlg2::IDD, this));
VERIFY(pDlg3.Create(PanelDlg2::IDD, this));
::SetParent(pDlg1.GetSafeHwnd(), this->m_hWnd);
::SetParent(pDlg2.GetSafeHwnd(), this->m_hWnd);
::SetParent(pDlg3.GetSafeHwnd(), this->m_hWnd);
Now I can show or hide a child dialog at will (button clicks) as below:
pDlg1.ShowWindow(SW_SHOW);
pDlg2.ShowWindow(SW_HIDE);
pDlg3.ShowWindow(SW_HIDE);
I need to create dialog and button.When I click on button with arrow dialog hide, it should looks like dialog moves to top and in ahother case shows for user.
ShowWindow(SW_HIDE). I know about it. I guess to get CRect from window, change it and after that set it to ScreeToClient().
Probably somebody knows some examples with it or another ways?
thanks
To hide or show a window, you use ShowWindow() as you indicated. No rectangle needed.
Otherwise, please re-explain your question, I can't make head or tails of it.
Normally, if you need to show a dialog that contains settings (similar to the Visual Studio "Options" dialog) then what you would typically do is this:
List item.
Create a CDialog-derived class.
Create an instance of that class.
call DoModal on that object. This shows the dialog.
Do nothing else. Once DoModal returns the dialog has been closed.
In C++, is there anyway to let the user chose the icon of the app? For example, Winamp lets you select which icon you wish to use from a list of icons in it's preferences. How is it done?
There is the icon that you see in explorer. This is a resource in your executable. You could change that, but I wouldn't advise you too. Virus scanners can get nervous if executables are modified, and in Windows Vista you will not even be allowed to write in the Program Files folder.
But the icon that is displayed on the task bar or in the system tray can be changed. This is actually the icon of your application window and it can be set by sending a WM_SETICON message.
And there are shortcuts. They can be changed too, and in a shortcut you can specify which icon should be used.
I found a discussion on changing icons that has information about the first two options.
For Visual Studio 2010 in an MFC dialog based app
A. In the resource view, rightclick Icon folder and add icon. Give it an ID like IDI_MYICON. Leave it as is or draw something nice.
B. Go to OnInitDialog. Add the following two lines of code:
HICON hMyIcon = LoadIcon( AfxGetInstanceHandle(), MAKEINTRESOURCE(IDI_MYICON) );
SetIcon( hMyIcon, FALSE ); // FALSE == use as small icon
You can read about these functions in the help to understand what is happening.
This sets the icon as icon for the sysmenu (topleft) and in the taskbar. This is however not automatically reflected in all situations. E.g. for a systray icon you need to explicitly specify the icon again in the call to Shell_NotifyIcon().
Can we create a CMFCRebar on a dialog box? If yes, then how? I need to have a CMFCReBar drawn on a dialog box with a toolbar and and menubar.
There are a lot of examples of how to add a toolbar to a CDialog. Have you tried to take one of those samples and modify CDialog with the new CDialogEx and CRebar with CMFCReBar? I haven't tried it but maybe it works.
By the way, there is a tag specific for MFC feature pack questions (mfc-feature-pack). Maybe you should add this tag.
