Is it possible to get the height of the titlebar of a modeless CDialog? I have this code currently which fits the CDialog exactly into my ImageBox. I want it to fit such that the client area has the exact fit to the imagebox, and the titlebar extends above.

    CRect picRect;

    m_THBImage6.GetWindowRect(&picRect);

pdlg0->SetWindowPos(&CWnd::wndNoTopMost,picRect.left,picRect.top,picRect.Width(),picRect.Height(),SWP_SHOWWINDOW );
pdlg0->ShowWindow(SW_SHOW);

MSDN doesnt say, but does Width() return the number of pixels? In that case, I'd need to know the titlebar height in pixels too. I am thinking that the new code to do what I want would be:

    CRect picRect;

    m_THBImage6.GetWindowRect(&picRect);


pdlg0->SetWindowPos(&CWnd::wndNoTopMost,picRect.left,picRect.top,picRect.Width(),<code>picRect.Height()+ titleBarHeight</code>,SWP_SHOWWINDOW );
pdlg0->ShowWindow(SW_SHOW);

Highliting items in list control

You'll have to add handler/message map entry (ON_MESSAGE) manually. Check ON_MESSAGE docs for more info.

SetItemState(itemIndex, LVIS_SELECTED, LVIS_SELECTED);

or

SetItemState(itemIndex, LVIS_SELECTED | LVIS_FOCUSED, LVIS_SELECTED | LVIS_FOCUSED);

You will most likely have to implement a custom draw algorithm for a specific line. Browse the list control section of CodeProject and CodeGuru for examples.

To enable full row highlighting in a list control:

m_ctrlList.SetExtendedStyle(m_ctrlList.GetExtendedStyle() | LVS_EX_FULLROWSELECT);

What's wndTop?

I got the following suggestion (which worked, thanks) from one of you. Could anyone tell me where the wndTop argument came from and what it does? I did not declare it nor saw it anywhere in my code.

m_ProgBar.SetWindowPos(&wndTop,//???where did it come from?
rect.left,
rect.top,
rect.Width(),
rect.Height(),
NULL);

Thanks

CWnd::wndTop is MFC wrapper for HWND_TOP constant. Since you can't use constant where CWnd* is required, they had to create static object representing HWND_TOP value.

CListCtrl question

RK_200012-Sep-02 6:59

I have created a custom, called CCustomListCtrl that inherits from CListCtrl. The only reason for this was to use the CustomDraw features.

I am using this CCustomCtrl in a dialog box and I have created it dynamically as following:

DWORD dwStyle;
dwStyle = LVS_REPORT | WS_VISIBLE | WS_CHILD | WS_HSCROLL | WS_VSCROLL | WS_BORDER | LVS_SINGLESEL ;

m_ControllerList.Create(dwStyle,
CRect(nLeft, nTop, nRight, nBottom), this, IDC_CONTROLLER_LIST);

m_ControllerList.SetExtendedStyle(LVS_EX_CHECKBOXES | LVS_EX_FULLROWSELECT | LVS_EX_INFOTIP);

Now, I don't have trouble catching any of the messages pertaining to the list within the CDialog class but it seems like messages pertaining to the header of the list (i.e. ColumnClick, etc) are all going to the CCustomCtrl file and I just don't seem to be able to trap them in my dialog class.

any ideas?

List control header's ID is zero. If you add handlers with ClassWizard, the message map entry will have control ID of your list, not zero. You'll have to change the ID value in message map or override OnNotify.

You can use custom draw without creating new CListCtrl-based class. Message reflection makes it possible - handler will be created in dialog class and invoked whenever list needs painting.

That's how WM_NOTIFY works. A notification sent by a control (in this case, the header) goes to the control's parent (the list).

MS Word in a Container

I am currently trying to work with COM and make a container to hold a Word document. What is happening is that I create the frame window, then insert the Word document, and it does what it should, it brings up the doc, puts the Word toolbars and menus on the window, etc. But one thing it does that is strange is that it has several of the toolbar buttons disabled. The Open, New, and Save buttons are disabled. Also, the Print button is enabled but when I click on it, it doesn't do anything. Other buttons, such as the spell check work fine. Everything seems to work fine when using the menus. Does anyone know why these buttons are disabled? How to enable these buttons? Anything about this issue?

I looked through several articles, such as the Using MS Office in an MFC Application but that doesn't ever mention anything like this....

Buttons in a CListCtrl

Hi,

How can i place buttons in a list control? Do i need declare the CListCtrl's and buttons' styles as owner drawn?
Do i need to override OnDrawItem function of CListCtrl because it takes DRAWITEMSTRUCT parameter which has a CtlType member that can take an ODT_BUTTON value. If not, how should i do that?

Help me out on this one please.

Thanks in advance.

Tomasz Sowinski12-Sep-02 7:44

Going owner-draw and setting CtlType won't take you anywhere; CtlType is set by Windows.

Do you want to create a column of buttons in your list control?

Yes, i want one column of the control to have buttons. Actually, my aim is to make the user insert rows and the button will be created at runtime. But i don't know how to create unique IDs at runtime and how to handle messages for the new buttons. This is a further step but if you have any suggestions on this problem too, i would love to hear it.

For placing button in list, i found a way like below:

Adding the following code in OnPaint or OnCreate function does it:

CRect itemRect;
GetSubItemRect( 0, 0, LVIR_LABEL, itemRect );

CTeamButton *buttonx = new CTeamButton;
buttonx->Create( "Test", WS_CHILD|WS_VISIBLE, itemRect, this, 12345 );

But it doesn't seem to be a solid and gentle way. For example, when you resize the columns the buttons' size doesn't change. It would get worse when sorting takes place. So i can't count on it. Is there any subtle way to achieve this?

Thanks.

I'm afraid not. You may consider switching to grid control instead, especially if you plan to add editing capabilities.

http://www.codeproject.com/miscctrl/gridctrl.asp[^]

If you want to stay with CListCtrl, I think it's better to give up 'real' buttons and simulate them with custom-draw or owner-draw.
