CMFCToolBar LoadToolBarEx fails for toolbar in CDialogEx - c++

I'm trying to use LoadToolBarEx however it always return 0 and no images appear in the toolbar, however if I use LoadBitmap the images load into the toolbar just fine.
My resource image is a PNG 32bit, 32x128 pixels, giving 4 button images.
When using LoadToolBarEx:
When using LoadBitmap:
Contained in OnInitDialog:
DWORD dwCtrlStyle = TBSTYLE_FLAT | TBSTYLE_TOOLTIPS | CBRS_SIZE_DYNAMIC;
DWORD dwStyle = AFX_DEFAULT_TOOLBAR_STYLE;
if (m_ToolBar.CreateEx(this, dwCtrlStyle,
dwStyle, CRect(1, 1, 1, 1), IDR_TOOLBAR1_PNG))
{
dwStyle = CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC;
m_ToolBar.SetPaneStyle(m_ToolBar.GetPaneStyle() | dwStyle);
}
CMFCToolBarInfo info;
m_ToolBar.SetSizes(CSize(32, 32), CSize(32, 32));
BOOL ret1 = m_ToolBar.LoadToolBarEx(IDR_TOOLBAR1_PNG,info,FALSE); // << THIS FAILS
BOOL ret2 = m_ToolBar.LoadBitmap(IDR_TOOLBAR1_PNG); // << THIS WORKS
CMFCToolBarButton but1(0, 0, L"HELLO", TRUE, 0);
CMFCToolBarButton but2(1, 1, L"HELLO", TRUE, 0);
CMFCToolBarButton but3(2, 2, L"HELLO", TRUE, 0);
but3.SetStyle(but3.m_nStyle | TBBS_DISABLED);
m_ToolBar.InsertButton(but1, 0);
m_ToolBar.InsertButton(but2, 0);
m_ToolBar.InsertButton(but3, 0);
m_ToolBar.SetToolBarBtnText(0, _T("By"));
m_ToolBar.SetToolBarBtnText(1, _T("Your"));
m_ToolBar.SetToolBarBtnText(2, _T("Command"));
m_ToolBar.InsertSeparator(2);
m_ToolBar.SetWindowPos(0, 0, 0, 400, 36, 0, 0);
In the TestDlg.rc I have:
//////////////////////////////////////////////////
//
// PNG
//
IDR_TOOLBAR1_PNG PNG "res\\toolbarNEW.png"
//////////////////////////////////////////////////
//
// Toolbar
//
//////////////////////////////////////////////////
In resource.h:
#define IDR_TOOLBAR1_PNG 135
What could be causing LoadToolBarEx to fail? there is no useful error code to work from, and I've tried various image format combinations so I don't believe it's an issue with the image resource.

How should I change the IMAGE(doesn't matter the type) of the button in the toolbar in MFC applications?

I know that this is stupid problem but I am stuck with it for the past 4 days. Why it is so complicated to just modify the toolbar in the MFC apps?
I create New Visual studio MFC application that is dialog based. I create new Toolbar resource. And then how should I set images(png, bitmap, jpeg...) or whatever type to be used in my toolbar?
I have set size to w50 and h50 and I can draw inside the buttons. But I cant find way to use image.
Instead this 2 buttons that I have just tried if its working, I want to use 8 images that are in bitmap format and in png. I read somewhere that PNG is not supported by MFC applications so I converted to Bitmap.
I load my toolbar in the dialog app like this in the OnInitDialog() method:
DWORD dwCtrlStyle = TBSTYLE_FLAT | TBSTYLE_TOOLTIPS | CBRS_SIZE_DYNAMIC;
DWORD dwStyle = AFX_DEFAULT_TOOLBAR_STYLE;
CMFCToolBar::m_dblLargeImageRatio = 1;
if (m_ToolBar.CreateEx(this, dwCtrlStyle, dwStyle, CRect(1, 1, 1, 1), IDR_TOOLBAR1))
{
dwStyle = CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC;
m_ToolBar.SetPaneStyle(m_ToolBar.GetPaneStyle() | dwStyle);
CMFCToolBarInfo info;
m_ToolBar.LoadToolBarEx(IDR_TOOLBAR1, info, FALSE);
CSize sizeToolBar = m_ToolBar.CalcFixedLayout(TRUE, TRUE);
m_ToolBar.SetWindowPos(NULL, 0, 0, sizeToolBar.cx, sizeToolBar.cy, SWP_NOACTIVATE |
SWP_NOZORDER);
CPoint ptOffset(0, sizeToolBar.cy);
}
Please if someone can help me I would be really grateful. The image format doesn't matter. I just want to put image in the toolbar.
This is my app currently:
UPDATE: I have tried this way. ID_BUTTON_1 if the first button in the toolbar and i tried to change its image. But with this there is no button in the toolbar at the place for the first button. What I am doing Wrong?
VERIFY(m_toolbar.LoadBitmap(IDB_BITMAP1));
CMFCToolBarButton mbutton;
mbutton.SetImage(m_toolbar.GetImages()->GetCount() - 1);
m_toolbar.ReplaceButton(ID_BUTTON_1, CMFCToolBarButton(ID_BUTTON_1, 0));
I answered this recently and can no longer find my answer. You can use PNG images for your toolbars. Under the hood you still use the BMP version for the resource editor to create your event handlers etc. But you can then add your PNG as a resource and then load it into your dialog.
For example, I call this in my OnInitDialog function:
void CMeetingScheduleAssistantDlg::CreateToolbar()
{
DWORD dwCtrlStyle = TBSTYLE_FLAT | TBSTYLE_TOOLTIPS | CBRS_SIZE_DYNAMIC;
DWORD dwStyle = AFX_DEFAULT_TOOLBAR_STYLE;
CMFCToolBar::m_dblLargeImageRatio = 1; // AJT v20.1.7 Bug fix
if (m_ToolBar.CreateEx(this, dwCtrlStyle,
dwStyle, CRect(1, 1, 1, 1), IDR_TOOLBAR))
{
dwStyle = CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC;
m_ToolBar.SetPaneStyle(m_ToolBar.GetPaneStyle() | dwStyle);
CMFCToolBarInfo info;
info.m_uiColdResID = IDB_PNG_MAIN_TOOLBAR;
info.m_uiHotResID = IDB_PNG_MAIN_TOOLBAR;
info.m_uiLargeColdResID = IDB_PNG_MAIN_TOOLBAR;
info.m_uiLargeHotResID = IDB_PNG_MAIN_TOOLBAR;
m_ToolBar.LoadToolBarEx(IDR_TOOLBAR, info, FALSE);
CSize sizeToolBar = m_ToolBar.CalcFixedLayout(TRUE, TRUE);
m_ToolBar.SetWindowPos(NULL, 0, 0, sizeToolBar.cx, sizeToolBar.cy,
SWP_NOACTIVATE | SWP_NOZORDER);
// Move all controls down
CPoint ptOffset(0, sizeToolBar.cy);
CRect rcChild;
CWnd* pwndChild = GetWindow(GW_CHILD);
while (pwndChild)
{
if (pwndChild->GetSafeHwnd() != m_ToolBar.GetSafeHwnd())
{
pwndChild->GetWindowRect(rcChild);
ScreenToClient(rcChild);
rcChild.OffsetRect(ptOffset);
pwndChild->MoveWindow(rcChild, FALSE);
}
pwndChild = pwndChild->GetNextWindow();
}
// Resize the window
CRect rcWindow;
GetWindowRect(rcWindow);
rcWindow.bottom += sizeToolBar.cy;
MoveWindow(rcWindow, FALSE);
}
}
I don't know where my previous answer has gone to, else I would have flagged this as duplicate. #confused.

How to create buttons of diffrent sizes in a toolbar control (Win32 API)

I want to insert buttons of diffrent sizes in a toolbar.
Lets say for example 2 buttons. One have a size of 32x16, the Other 16x16.
I used Two Image Lists. Each image list has it's own image size (1st 32x16 - 2nd 16x16).
But the problem is, when I compile the code i get the images loaded correctly but the buttons have the same width(32).
code:
//(1) Create the Toolbar ImageList
HIMAGELIST hImageListLarge = ImageList_Create(32, 16, ILC_COLOR8 | ILC_MASK, 1, 0);
if (!hImageListLarge)
return false;
HIMAGELIST hImageListSmall = ImageList_Create(16, 16, ILC_COLOR8 | ILC_MASK, 1, 0);
if (!hImageListSmall)
return false;
//(2) Fill the Image List
if (ImageList_Add(hImageListLarge,
LoadBitmap(m_hInstance, MAKEINTRESOURCE(IDB_TB_CONNECT_TO)),
LoadBitmap(m_hInstance, MAKEINTRESOURCE(IDB_TB_CONNECT_TO_MASK))) == -1)
return false;
if (ImageList_Add(hImageListSmall,
LoadBitmap(m_hInstance, MAKEINTRESOURCE(IDB_TB_HELP)),
LoadBitmap(m_hInstance, MAKEINTRESOURCE(IDB_TB_HELP_MASK))) == -1)
return false;
//(3) Create the Toolbar window
m_hToolbar = CreateWindowEx(0, TOOLBARCLASSNAME, nullptr,
WS_CHILD | TBSTYLE_WRAPABLE | TBSTYLE_AUTOSIZE | TBSTYLE_LIST | TBSTYLE_TOOLTIPS ,
0, 0, 0, 0, m_hWnd, nullptr, m_hInstance, nullptr);
if (m_hToolbar == nullptr)
return false;
//(4) Sets the Image list for the Toolbar

//(5) Initialize the TBBUTTON structures for each button
m_tbButtons[0].fsStyle = BTNS_SEP;
m_tbButtons[1].iBitmap = MAKELONG(0, 0);
m_tbButtons[1].idCommand = ID_CONNECTIONS_CONNECT_TO;
m_tbButtons[1].fsState = TBSTATE_ENABLED;
m_tbButtons[1].fsStyle = BTNS_BUTTON | BTNS_AUTOSIZE;
m_tbButtons[1].iString = (INT_PTR)TEXT("Connect to");
m_tbButtons[2].iBitmap = MAKELONG(0, 1);
m_tbButtons[2].idCommand = ID_HELP_ABOUT;
m_tbButtons[2].fsState = TBSTATE_ENABLED;
m_tbButtons[2].fsStyle = BTNS_BUTTON | BTNS_AUTOSIZE ;

//(8) Modify the size of the separator that will hold the combobox
TBBUTTONINFO tbbi;
tbbi.cbSize = sizeof(tbbi);

(HMENU)IDC_COMBO_HOSTS, m_hInstance, nullptr);
if (!m_hComboHosts)
return false;
return true;
After a quick check, please modify the following code:
Comment this line of codeļ¼š
SendMessage(m_hToolbar, TB_SETEXTENDEDSTYLE, 0, (LPARAM)TBSTYLE_EX_MIXEDBUTTONS);
TBSTYLE_EX_MIXEDBUTTONS
Version 5.81. This style allows you to set text for all buttons, but
only display it for those buttons with the BTNS_SHOWTEXT button style.
The TBSTYLE_LIST style must also be set. Normally, when a button does
not display text, your application must handle TBN_GETINFOTIP or
TTN_GETDISPINFO to display a tooltip. With the TBSTYLE_EX_MIXEDBUTTONS
extended style, text that is set but not displayed on a button will
automatically be used as the button's tooltip text. Your application
only needs to handle TBN_GETINFOTIP or or TTN_GETDISPINFO if it needs
more flexibility in specifying the tooltip text.
When you set TBSTYLE_EX_MIXEDBUTTONS style, it will allow you to set text for all buttons.
After testing, this style will prevent you from changing the width of the button.
If you want to display the button text, just add the BTNS_SHOWTEXT style.
Modified code:
//(1) Create the Toolbar ImageList
HIMAGELIST hImageListLarge = ImageList_Create(32, 16, ILC_COLOR8 | ILC_MASK, 1, 0);
if (!hImageListLarge)

(HMENU)IDC_COMBO_HOSTS, hInst, nullptr);
if (!m_hComboHosts)
return false;
return true;
I used the first TB_SETBUTTONINFO message to modify the size of a button (Separator).
To make it large enough for holding a comboBox control:
//(8) Modify the size of the separator that will hold the combobox
TBBUTTONINFO tbbi;
tbbi.cbSize = sizeof(tbbi);
tbbi.dwMask = TBIF_SIZE | TBIF_BYINDEX;
tbbi.cx = 500;
SendMessage(m_hToolbar, TB_SETBUTTONINFO, (WPARAM)0, (LPARAM)& tbbi);
This is the code for creating the ComboBox:
//(9) Get the Rectangle occupied by the separator
RECT rcSep;
SendMessage(m_hToolbar, TB_GETITEMRECT, (WPARAM)0, (LPARAM)& rcSep);
//(10) Create the hosts comboBox
m_hComboHosts = CreateWindow(WC_COMBOBOXW, nullptr, WS_CHILD | CBS_DROPDOWN | WS_VISIBLE,
rcSep.left, rcSep.top, rcSep.right - rcSep.left, rcSep.bottom - rcSep.top, m_hToolbar,
(HMENU)IDC_COMBO_HOSTS, m_hInstance, nullptr);
This is working as expected.
But when I try to add two other buttons (32x16 - 16x16), I get always the same width of the first Imagelist (32).
But when I swap the image list indexes, I get (16 for both).
I am using the new Visual styles ComCtl32.lib

Why is my CMFCToolBar overlapped on CDialog?

I am at the design stage here.
Code:
if (m_ToolBar.CreateEx(this, TBSTYLE_TRANSPARENT | TBSTYLE_FLAT,
AFX_DEFAULT_TOOLBAR_STYLE, CRect(1, 1, 1, 1), IDR_TOOLBAR))
{
m_ToolBar.SetPaneStyle(m_ToolBar.GetPaneStyle()
& ~(CBRS_GRIPPER | CBRS_SIZE_DYNAMIC | CBRS_BORDER_ANY));
m_ToolBar.SetBorders();
m_ToolBar.LoadBitmap(IDB_BMP_SM_IMAGELIST);
m_ToolBar.InsertButton(CMFCToolBarButton(ID_FILE_OPEN_CHRISTIAN_LIFE_AND_MINISTRY_REPORT, 0, _T("Open MWB"), TRUE));
m_ToolBar.InsertButton(CMFCToolBarButton(ID_FILE_CREATE_CHRISTIAN_LIFE_AND_MINISTRY_REPORT, 0, _T("Create MWB"), TRUE));
m_ToolBar.InsertSeparator(2);
m_ToolBar.InsertButton(CMFCToolBarButton(ID_FILE_OPENREPORT, 0, _T("Open SRR"), TRUE));
m_ToolBar.InsertButton(CMFCToolBarButton(ID_FILE_CREATEREPORT, 0, _T("Create SRR"), TRUE));
m_ToolBar.InsertSeparator(5);
m_ToolBar.InsertButton(CMFCToolBarButton(ID_OPTIONS_PUBLISHERS_DATABASE, 0, _T("Publishers Database"), TRUE));
CSize sizeToolBar = m_ToolBar.CalcFixedLayout(FALSE, TRUE);
m_ToolBar.SetWindowPos(NULL, 0, 10, sizeToolBar.cx, sizeToolBar.cy,
SWP_NOACTIVATE | SWP_NOZORDER);
}
I call the above in OnInitDialog of my CDialog.
Why is the toolbar overlapped:
Update
I simplified the code to just use a basic toolbar resource:
if (m_ToolBar.CreateEx(this, TBSTYLE_TRANSPARENT | TBSTYLE_FLAT,
AFX_DEFAULT_TOOLBAR_STYLE, CRect(1, 1, 1, 1), IDR_TOOLBAR))
{
m_ToolBar.SetPaneStyle(m_ToolBar.GetPaneStyle()
& ~(CBRS_GRIPPER | CBRS_SIZE_DYNAMIC | CBRS_BORDER_ANY));
m_ToolBar.SetBorders();
m_ToolBar.LoadToolBar(IDR_TOOLBAR);
CSize sizeToolBar = m_ToolBar.CalcFixedLayout(TRUE, TRUE);
m_ToolBar.SetWindowPos(NULL, 0, 10, sizeToolBar.cx, sizeToolBar.cy,
SWP_NOACTIVATE | SWP_NOZORDER);
}
But the results are still the same.
Update
I noticed if I just resize my dialog in the IDE that I then have room for the toolbar. But how to do I accurately resize it in the IDE to allow for a 32 pixel high toolbar?
Someone provided a link to this archived article.
This is my updated code (called from OnInitDialog):
void CMeetingScheduleAssistantDlg::CreateToolbar()
{
DWORD dwCtrlStyle = TBSTYLE_FLAT | TBSTYLE_TOOLTIPS | CBRS_SIZE_DYNAMIC;
DWORD dwStyle = AFX_DEFAULT_TOOLBAR_STYLE;
if (m_ToolBar.CreateEx(this, dwCtrlStyle,
dwStyle, CRect(1, 1, 1, 1), IDR_TOOLBAR))
{
dwStyle = CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC;
m_ToolBar.SetPaneStyle(m_ToolBar.GetPaneStyle() | dwStyle);
CMFCToolBarInfo info;
info.m_uiColdResID = IDB_PNG_MAIN_TOOLBAR;
info.m_uiHotResID = IDB_PNG_MAIN_TOOLBAR;
info.m_uiLargeColdResID = IDB_PNG_MAIN_TOOLBAR;
info.m_uiLargeHotResID = IDB_PNG_MAIN_TOOLBAR;
m_ToolBar.LoadToolBarEx(IDR_TOOLBAR, info, FALSE);
CSize sizeToolBar = m_ToolBar.CalcFixedLayout(TRUE, TRUE);
m_ToolBar.SetWindowPos(NULL, 0, 0, sizeToolBar.cx, sizeToolBar.cy,
SWP_NOACTIVATE | SWP_NOZORDER);
// Move all controls down
CPoint ptOffset(0, sizeToolBar.cy);
CRect rcChild;
CWnd* pwndChild = GetWindow(GW_CHILD);
while (pwndChild)
{
if (pwndChild->GetSafeHwnd() != m_ToolBar.GetSafeHwnd())
{
pwndChild->GetWindowRect(rcChild);
ScreenToClient(rcChild);
rcChild.OffsetRect(ptOffset);
pwndChild->MoveWindow(rcChild, FALSE);
}
pwndChild = pwndChild->GetNextWindow();
}
// Resize the window
CRect rcWindow;
GetWindowRect(rcWindow);
rcWindow.bottom += sizeToolBar.cy;
MoveWindow(rcWindow, FALSE);
}
}
In short I had to manually move down all controls and resize the window. Looks OK now:

CMFCPropertySheet "Page" resources are not resizing with dynamic layout

I am really confused. :(
Here is a new property sheet:
#include "stdafx.h"
#include "resource.h"
#include "VisitsRotaMFCPropertySheet.h"
CVisitsRotaMFCPropertySheet::CVisitsRotaMFCPropertySheet()
:CResizingMFCPropertySheet(_T("VisitsRota"), AFX_IDS_APP_TITLE, nullptr, 0)
{
ConstructSheet();
}
CVisitsRotaMFCPropertySheet::~CVisitsRotaMFCPropertySheet()
{
}
BOOL CVisitsRotaMFCPropertySheet::OnInitDialog()
{
BOOL bResult = CResizingMFCPropertySheet::OnInitDialog();
m_Menu.LoadMenu(IDR_MENU);
SetMenu(&m_Menu);
return bResult;
}
void CVisitsRotaMFCPropertySheet::ConstructSheet()
{
m_psh.dwFlags |= PSH_NOAPPLYNOW;
AddPage(&m_ElderlyInfirmPage);
AddPage(&m_ShepherdingPage);
}
It is derived from CResizingMFCPropertySheet. This is the source for that class:
https://www.dropbox.com/s/fzpfo4c3dpt6l51/ResizingMFCPropertySheet.cpp?dl=0
Now, I have two pages in this window. Here is one for the definitions:

It is correctly set up as a page and I have initially set the control data via the IDE:

END
I have adjusted my CDialog application to invoke the property sheet instead. The sheet itself sizes:
Why is the sheet control not automatically resizing? I just don't get it. My other application uses the same base class and yet all those property pages correctly resizing the controls etc using the dynamic layout features.
Update
I added this to one of my pages:
void CElderlyInfirmPage::OnSize(UINT nType, int cx, int cy)
{
CMFCPropertyPage::OnSize(nType, cx, cy);
AfxMessageBox(_T("Size"));
// TODO: Add your message handler code here
auto pManager = GetDynamicLayout();
if (pManager != nullptr)
{
AfxMessageBox(_T("Valid"));
}
}
It confirms that the "page" does not actually have a dynamic layout manager. Only the sheet does. So I think the problem is the fact that we can't use dynamic layout mechanism.
Update 2
I made some progress. Example:
It turns out that the property page doesn't seem to load the dynamic layout resources like it does for a dialog. I started to create it manually:
BOOL CElderlyInfirmPage::OnInitDialog()
{
CMFCPropertyPage::OnInitDialog();
// TODO: Add extra initialization here
ReadSettings();
InitMonthCombo();
// Init to THIS month
COleDateTime datNow = COleDateTime::GetCurrentTime();

}
As you can see, the controls move now so it is progress. But the problem now is that I have a lot of IDC_STATIC controls on these pages and I don't want to change the ID numbers. This is because the application already has translations for localization and if I change the ID values I blow up the translations. So I am wondering if I can use the [CMFCDynamicLayout::LoadResource][3] method to load the complete settings from the RC file. But I can't work out how to call LoadResource here. I am sure it would be the answer to this question.
Update 3
I just traced the code and if you look here:
LRESULT CPropertySheet::HandleInitDialog(WPARAM, LPARAM)
{
LRESULT lResult = OnInitDialog();
CMFCDynamicLayout* pDynamicLayout = GetDynamicLayout();
if (pDynamicLayout != NULL)
{
CRect rectWindow;
GetWindowRect(rectWindow);
m_sizeMin = rectWindow.Size();
for (CWnd *pChild = GetWindow(GW_CHILD); pChild->GetSafeHwnd() != NULL; pChild = pChild->GetWindow(GW_HWNDNEXT))
{
HWND hwndChild = pChild->GetSafeHwnd();
if (!pDynamicLayout->HasItem(hwndChild))
{
if (pChild->SendMessage(WM_GETDLGCODE) & DLGC_BUTTON)
{
pDynamicLayout->AddItem(hwndChild, CMFCDynamicLayout::MoveHorizontalAndVertical(100, 100), CMFCDynamicLayout::SizeNone());
}
else if (IsLeftNavigationPane(hwndChild))
{
pDynamicLayout->AddItem(hwndChild, CMFCDynamicLayout::MoveNone(), CMFCDynamicLayout::SizeVertical(100));
}
else if (DYNAMIC_DOWNCAST(CPropertyPage, pChild) == NULL || CanAddPageToDynamicLayout())
{
pDynamicLayout->AddItem(hwndChild, CMFCDynamicLayout::MoveNone(), CMFCDynamicLayout::SizeHorizontalAndVertical(100, 100));
}
}
}
}
return lResult;
}
It does not seem to actually work with the layout properly.
I tried to use:
LoadDynamicLayoutResource(m_lpszTemplateName);
And I traced it. It eventually ended up here:
BOOL CMFCDynamicLayout::LoadResource(CWnd* pHostWnd, LPVOID lpResource, DWORD dwSize)
{
if (pHostWnd->GetSafeHwnd() == NULL || !::IsWindow(pHostWnd->GetSafeHwnd()) || lpResource == NULL)
{
return FALSE;
}
CMFCDynamicLayoutData layoutData;
BOOL bResult = layoutData.ReadResource(lpResource, (UINT)dwSize);
layoutData.ApplyLayoutDataTo(pHostWnd, FALSE);
return bResult;
}
It failed on the ApplyLayoutDataTo call, on the first if statement:
BOOL CMFCDynamicLayoutData::ApplyLayoutDataTo(CWnd* pHostWnd, BOOL bUpdate)
{
if (pHostWnd->GetSafeHwnd() == NULL || m_listCtrls.IsEmpty())
{
return FALSE;
}
ASSERT_VALID(pHostWnd);
pHostWnd->EnableDynamicLayout(FALSE);
pHostWnd->EnableDynamicLayout();
m_listCtrls.IsEmpty() was empty. So it hadn't read it in properly anyway.
I think I have no choice but to assign IDs to all my controls, even the static ones and manually build the dynamic layout up. Unless you have other ideas.
Dynamic layout is already be enabled for all classes derived from CDialog which call the default CDialog::OnInitDialog, which in turn uses CMFCDynamicLayout::LoadResource to read resizing information for child controls.
That include CMFCPropertyPage. The information is already loaded, so if you call EnableDynamicLayout it deletes the existing object and creates a new one. Just remove the call to EnableDynamicLayout.
This way pManager->Create(this); won't be necessary, but you can keep it in there. It won't do anything because pManager already created and the method knows not to create twice.
CPropertySheet does require EnableDynamicLayout and pManager->Create. PropertySheet cannot be designed in dialog editor, so MFC ignores resizing for its child windows. Dynamic resizing has to be implemented manually.
MCVE:

CButton bn;

{
CMFCPropertyPage::OnInitDialog();
//add test button dynamically
bn.Create(L"Test", WS_CHILD | WS_VISIBLE, CRect(0, 0, 100, 30), this, 301);
auto pManager = GetDynamicLayout();
if(pManager != nullptr)

CMFCDynamicLayout::SizeNone());

updatelayeredwindow not working

i tried to use UpdateLayeredWindow for all day, but it failed to work :(, i put the code in OnCreate and load a png file (created by photoshop) with CImage.
int CMainWindow::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
SetWindowLong(this->m_hWnd, GWL_STYLE, 0);
SetWindowLong(this->m_hWnd, GWL_EXSTYLE, 0);
SetWindowLong(this->m_hWnd, GWL_EXSTYLE, GetWindowLong(this->m_hWnd, GWL_EXSTYLE) | WS_EX_LAYERED);
this->SetMenu(NULL);
::SetWindowPos(this->m_hWnd, HWND_TOP, 50, 50, 652, 492, SWP_SHOWWINDOW);
CBitmap imageBitmap, *oldBitmap;
CDC *dcWindow, dcMem;
CRect wRect;
CPoint wPos;
CSize wSize;
HBITMAP hbmp;
BLENDFUNCTION bFunc;
m_Image.Load(_T("Img/BG_Blue.png"));
GetWindowRect(&wRect);
dcWindow = GetWindowDC();
imageBitmap.CreateCompatibleBitmap(dcWindow, wRect.Width(), wRect.Height());
dcMem.CreateCompatibleDC(dcWindow);
oldBitmap = dcMem.SelectObject(&imageBitmap);
m_Image.Draw(dcMem.m_hDC, 0, 0, wRect.Width(), wRect.Height(), 0, 0, wRect.Width(), wRect.Height());
wPos.x = 0; wPos.y = 0;
wSize.cx = wRect.left; wSize.cy = wRect.bottom;
bFunc.SourceConstantAlpha = 125;
bFunc.BlendFlags = 0;
bFunc.BlendOp = AC_SRC_OVER;
bFunc.AlphaFormat = AC_SRC_ALPHA;
UpdateLayeredWindow(dcWindow, &wPos, &wSize, &dcMem, &wPos, 0, &bFunc, ULW_ALPHA);
//BitBlt(dcWindow->m_hDC, 0, 0, wRect.Width(), wRect.Height(), dcMem.m_hDC, 0, 0, SRCCOPY);
DWORD error = GetLastError();
dcMem.SelectObject(oldBitmap);
return 0;
}
the function returned with 1 , but nothing appeared on the screen, only an icon on the starup menu indicating the program is running. I am wondering if there is something wrong with the png file ... can anyone help ?
dcWindow should be the Device Context of the screen not the window. So initialize it like so: dcWindow->Attach(::GetDC(NULL)) instead of dcWindow = GetWindowDC();
