I've embedded a property sheet in a dialog box IDC_CONTAINER by specifying the HWND of the container in the hwndParent of the property sheet header when creating the property sheet. In the callback I specified the following...
int CALLBACK PSCallback (HWND hWnd, UINT message, LPARAM lParam)
{
LONG Z, Y;
switch (message)
{
case PSCB_PRECREATE: // Remove Title Bar and Borders.
// SO FAR border removal not working
((LPDLGTEMPLATE)lParam)->style &= ~WS_CAPTION;
break;
}
return 0;
}
The property sheet is displayed without a title bar as expected but with a border. I expected the border to go away since WS_CAPTION contains the border style per the MSDN.
Is there some way to get rid of the border?

I managed to do what I needed, see comments added to original posting.

I created an Outlook bar with tree controls and would like to have it auto size to always fully display the text of the tree control. Ideally the border in the picture would move so that "Healthcare Merchandising" is fully visible.
newDimbar is a CMFCOutlookBar object created in CMainFrame.
I have tried stretching it:
void CTreeDrill::OnTvnItemexpanded(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMTREEVIEW pNMTreeView = reinterpret_cast<LPNMTREEVIEW>(pNMHDR);
HTREEITEM hItem = pNMTreeView->itemNew.hItem;
RECT treeRect;
GetItemRect(GetChildItem(hItem), &treeRect, FALSE);
CMainFrame *pMain = (CMainFrame*)AfxGetMainWnd();
int iStretch = treeRect.right;
pMain->m_ctlNewDimBar.StretchPane(iStretch, FALSE);
EnsureVisible(GetChildItem(hItem));
}
and using move:
void CTreeDrill::OnTvnItemexpanded(NMHDR *pNMHDR, LRESULT *pResult)
{
RECT treeRect;
RECT newRect;
RECT dimRect;
GetItemRect(GetChildItem(hItem), &treeRect, FALSE);
CMainFrame *pMain = (CMainFrame*)AfxGetMainWnd();
pMain->m_ctlNewDimBar.GetWindowRect(&dimRect);
newRect = dimRect;
newRect.right = treeRect.right;
pMain->m_ctlNewDimBar.MoveWindow(newRect);
EnsureVisible(GetChildItem(hItem));
}
without luck. What am I missing?
Solution
I'm happy i found it because this is something i would have to do too in the future, you need to use CWnd::SetWindowPos to change the CMFCOutlookBar's size, check this tutorial that has more infos, after you change the size of CMFCOutlookBar you will have to use CFrameWndEx::RecalcLayout method of the frame that contains the CMFCOutlookBar.
Why using CWnd::SetWindowPos?
i don't know, it's the only one that worked for me
Why use CFrameWndEx::RecalcLayout and not only call RecalcLayout() of the CMFCOutlookBar?
Because if you just recalculate the layout of the CMFCOutlookBar only the CMFCOutlookBar will be updated and then if you have anything attached to the CMFCOutlookBar it will not recieve the changes, so you might end with your CMFCOutlookBar overlapping some other control or your document's view, calling CFrameWndEx::RecalcLayout will make the whole frame reacalculate and so if you have tabbed document views they will be updated/resized accordingly.
Your case
you will have to calculate the whole width of the tree, not only the item, and then use the CWnd::SetWindowPos on the CMFCOutlookBar with the updated value width value but keeping the height of the CMFCOutlookBar.
newDimbar.GetWindowRect(pos);
ScreenToClient(&pos);
UINT flags = SWP_NOZORDER | SWP_NOMOVE;
newDimbar.SetWindowPos(NULL, 0, 0, iNewWidth, pos.Height(), flags);
I'm a little new to using MFC and VC++ as such, but I'm doing this as part of a Course and i Have to stick to VC++.
http://www.cprogramming.com/tutorial/game_programming/same_game_part1.html
This is the tutorial I have been following to make a simple samegame. However when i try to display score, the score is getting displayed Underneath or outside my application window, even though I've displayed score before calling updateWindow(). I've tried various methods but I am kinda lost here.
Here is the code I'm using to Display the score:
void CSameGameView::updateScore()
{
CSameGameDoc* pDoc = GetDocument();
CRect rcClient, rcWindow;
GetClientRect(&rcClient);
GetParentFrame()->GetWindowRect(&rcWindow);
int nHeightDiff = rcWindow.Height() - rcClient.Height();
rcScore.top=rcWindow.top + pDoc->GetHeight() * pDoc->GetRows() + nHeightDiff;
rcScore.left=rcWindow.left + 50;
rcScore.right=rcWindow.left + pDoc->GetWidth() - 50;
rcScore.bottom=rcScore.top + 20;
CString str;
double points = Score::getScore();
str.Format(_T("Score: %0.2f"), points);
HDC hDC=CreateDC(TEXT("DISPLAY"),NULL,NULL,NULL);
COLORREF clr = pDoc->GetBoardSpace(-1, -1); //this return background colour
pDC->FillSolidRect(&rcScore, clr);
DrawText(hDC, (LPCTSTR) str, -1, (LPRECT) &rcScore, DT_CENTER);
}
Thank you for any help and I'm sorry if the question doesn't make sense or in ambiguous.
There are several problems with your code:
1. The hDC you are creating is going to have coordinates relative to the desktop window. To paint text in your window, use CClientDC like this: CClientDC dc(this); (see http://msdn.microsoft.com/en-US/library/s8kx4w44%28v=vs.80%29.aspx)
2. The code you have will leak a DC every time the function is called. The method in #1 will fix that.
3. Your paint code should be done in the CView::OnDraw. There you get a DC passed to you and you don't have to worry about creating one with CClientDC. Set the variables you want to draw (e.g. your points or score), store them as class members and draw them in CView::OnDraw.
Don't do the drawing in your updateScore method.
Make sense? Hang in there!
How could I Add Minimize and Maximize box to the system menu of CMFCPropertySheet.
I have tried modifying the style by
CMFCPropertySheet::ModifyStyle(NULL, WS_SYSMENU);
but nothing happened.
Assuming you have a class derived from CPropertySheet, let's call it MySheet:
// Capture the WM_NCREATE message
BEGIN_MESSAGE_MAP(CMySheet, CPropertySheet)
ON_WM_NCCREATE()
END_MESSAGE_MAP()
BOOL CMySheet::OnNcCreate(LPCREATESTRUCT lpCreateStruct)
{
if (!CPropertySheet::OnNcCreate(lpCreateStruct))
return FALSE;
// Modify the window style
LONG dwStyle = ::GetWindowLong(m_hWnd, GWL_STYLE);
::SetWindowLong(m_hWnd, GWL_STYLE, dwStyle | WS_WS_MINIMIZEBOX | WS_MAXIMIZEBOX);
return TRUE;
}
Note that you could do this in the OnInitDialog, but even though the Minimize/Maximize boxes will show, they won't do anything.
doing just this in the "OnInitDialog:" worked for me.
LONG dwStyle = ::GetWindowLong(m_hWnd, GWL_STYLE);
::SetWindowLong(m_hWnd, GWL_STYLE, dwStyle | WS_WS_MINIMIZEBOX | WS_MAXIMIZEBOX);
I have a resizeable CListCtrl and I want to avoid any item being displayed partially, ever.
For example:
I want Item 9 to not be displayed in this case. Is there a flag or method for this? How would you go about solving this issue?
I tried the following and it was no good:
void CMyCListCtrl::OnEndScrolling()
{
int iCount = this->GetCountPerPage();
EnsureVisible(iCount - 1, FALSE);
}
after catching
...
ON_NOTIFY( LVN_ENDSCROLL, IDC_LIST1, OnEndScroll )
...
void CWheelTestDlg::OnEndScroll(NMHDR* pNMHDR, LRESULT* pResult)
{
LPNMLVSCROLL pnmLVScroll = (LPNMLVSCROLL) pNMHDR;
m_MyListCtrl.OnEndScrolling();
*pResult = 0;
}
In the CListCtrl parent dialog. (which I don't want to do, I want to do everything in my CListCtrl derived class only, if possible).
All I accomplish is showing item 9 completely, but item 10 is partially visible below it. If I have 30 items I don't want to scroll the list to show item 30, I want to show up to item 8 with no partially visible item below it.
CListCtrl doesn't appear to support Integral Height.
Here's a solution that accomplishes what you desire by forcefully changing the control height [with commented conditions] (http://www.codeproject.com/Messages/418084/Socket-accept-call.aspx):
/////////////////////////////////////////////////////////////////////////////////
// This assumes a REPORT-style CListCtrl.
//
// Resize the control. This works correctly only if scrolling is disabled. If
// there is scrolling, then setting to the size from ApproximateViewRect() will
// always give scroll bars showing. Which is irritating.
//
// We need to adjust the vertical size from what ApproximateViewRect() returns
// by one row minus border width
//////////////////////////////////////////////////////////////////////////////////
CSize sz = m_list.ApproximateViewRect(); // always adds room for a new row
CRect itRect; // Get the height of a single row (there had better *be* a row!)
m_list.GetItemRect(0, &itRect, LVIR_BOUNDS);
int vOffset = itRect.Height() - 3; // leave a little 'cuz it looks better
m_list.SetWindowPos(NULL, 0, 0, sz.cx, sz.cy - vOffset,
SWP_NOZORDER|SWP_NOACTIVATE|SWP_NOMOVE);
I have the similar problem in wince, and find a solution accidentally. No direct solution in internet, so i decide to re-position scroll bar after receive some message, and the only message i can used in wince is WM_LBUTTONDOWN, other messages such as OnEndScroll are not called, maybe something wrong in my code.
Whatever, i use Timer（ON_WM_TIMER） to re-position scroll bar when receive WM_LBUTTONDOWN message, then find that list control doesn't scroll automatically! then i remain a empty OnTimer function and remove everything else. It works, and i guess list control use Timer to scroll partial row.
Hope useful to you.
I have a dialog that I want to place within another dialog and position relative to one of the controls on the main dialog.
void CspAceDlg::DrawResultsArea()
{
CWnd* pTabCtl = GetDlgItem(IDC_BUILDTABS);
CRect rectTabCtl; // Allocate CRect for control's position.
pTabCtl->GetWindowRect(&rectTabCtl);
int resX = rectTabCtl.right + 15;
int resY = rectTabCtl.top;
//RESULTS AREA
results.Create(IDD_RESULTSDIALOG, this);
results.SetWindowPos(this, resX, resY, /*608, 19, */175, 135, SWP_SHOWWINDOW);
results.ShowWindow(SW_SHOW);
}
My problem is that my dialog resource (IDD_REULTSDIALOG) has properties called X Pos and Y Pos that seem to be overriding my SetWindowPos() (and the little property tab in the resource editor won't let me leave these blank). If I set these properties to 0, 0 my dialog appears in the top left corner of the main dialog. If I set them to a number I can guess-and-test place it roughly where I want, but then running the application on different resolutions causes the dialog to appear in different spots. What I really want to do anyway is place the dialog relative to another control on my main dialog (in this case my tab control). Why is my SetWindowPos() being ignored, and how do I fix this? Should I be using a different function?
According to the documentation for SetWindowPos, if you pass in SWP_SHOWWINDOW, the window will not be moved:
If the SWP_SHOWWINDOW or SWP_HIDEWINDOW flag is set, the window cannot be moved or sized.
Figured it out myself, largely due to this thread.
My code came out looking like this:
void CspAceDlg::DrawResultsArea()
{
CRect rectTabCtl; // CRect representing tab control's position.
POINT pResXY;
POINT pResWH;
CWnd* pTabCtl = GetDlgItem(IDC_BUILDTABS);
pTabCtl->GetWindowRect(&rectTabCtl);
pResXY.x = rectTabCtl.right + 15;
pResXY.y = rectTabCtl.top;
pResWH.x = pResXY.x + 175;
pResWH.y = pResXY.y + 135;
ScreenToClient(&pResXY);
ScreenToClient(&pResWH);
//RESULTS AREA
results.Create(IDD_RESULTSDIALOG, this);
//results.SetWindowPos(this, resX, resY, /*608, 19, */175, 135, SWP_SHOWWINDOW);
results.MoveWindow(pResXY.x, pResXY.y, pResWH.x, pResWH.y, TRUE);
results.ShowWindow(SW_SHOW);
}
What fixed this problem for me, was setting the program's compatibility properties to "run this program as an administrator".
