Actually it's CSIDL_COMMON_APPDATA. CSIDL_APPDATA is the per-user Application Data dir.

No, never assume directories will have a particular name. Use SHGetFolderPath() with CSIDL_COMMON_APPDATA.

delete a CStatic Object

A CStatic object created on the stack within a window is automatically destroyed. If you create the CStatic object on the heap by using new , you must call delete on the object to destroy it when you are done with it.
~~delete myObj;~~
DestroyWindow();
To destroy a C++ Windows object, use DestroyWindow, not "delete".

Hi All,

Is there some class similar to CIPAddressCtrl (which is available in desktop MFC library), which
can be used in WinCE.NET platform, as MFC for Win CE does not support CIPAddressCtrl class?
If YES then plz tell me its details????

Regards
Frozen

I have a CTreeCtrl derived control which is populated in the OnInitDialog handler, and then all items are selected still in the OnInitDialog handler. The items are successfully selected but when the dialog displays only the first item is highlighted. Does anyone know what I need to add to get all the items highlighted automatically when the dialog is doisplayed?

Hello
I create a childview and also create process. I want to paint something in the childview. But I try to change the code in childview but some errors happen.

CString SelfTimer;
SelfTimer.Format(_T("%d"),_T("123"));
invalidateRect.SetRect(50,200,450,232);
HBRUSH hBrush = CreateSolidBrush(RGB(255,0,255));
::SetBkMode(g_hTimeMemDC, TRANSPARENT);
::FillRect(g_hTimeMemDC, &invalidateRect, hBrush);

::SetTextColor(g_hTimeMemDC,RGB(0,0,0));
::DrawText(g_hTimeMemDC, SelfTimer, -1, &invalidateRect, DT_LEFT | DT_TOP);
InvalidateRect(HWND(param), &invalidateRect, false);
DeleteObject(hBrush);

CPaintDC dc(HWND(param));
if(g_hTimeMemDC)

TransparentImage(dc.m_hDC,invalidateRect.left,invalidateRect.top,invalidateRect.Width(),invalidateRect.Height(), g_hTimeMemDC,invalidateRect.left,invalidateRect.top,invalidateRect.Width(),invalidateRect.Height(), RGB(255, 0, 255));

the build error is left of '.m_hDC' must have class/struct/union in TransparentImage function

who could I fix the issue or the way I program is wrong??

Any suggestion is useful!! Thanks!!

The application is to unuse the childview function but also want to paint in the childview. So I create a thread to paint out of childview.
When I push the button in childview, it set the event to the waitforsigleobject in ThreadProc and then paint the childview.

But I cannot build the codes successful, could u tell me what is wrong for the codes??

Any suggestion is useful!! Thanks!!

If you want to draw i think you need to WM_PAINT messageand if you use from this message i think you dont have problem.

tryin to create modeless dialog...
m_dlg->Create(CMyDlg::IDD, &m_tabctrl/*CTabCtrl*/);// ASSERT(pWnd->m_hWnd == NULL); // debug error

constructor:
CMyDlg::CMyDlg(CWnd* pParent /*=NULL*/)
//: CDialog(CMyDlg::IDD, pParent)
{
this->Create(CMyDlg::IDD, pParent);
this->ShowWindow(SW_NORMAL);

in the constructor it self the window is created. So why u gonne call Create again...?

And if u stick to the above code then code like this

if( m_dlg->m_hWnd )
{
m_dlg->DestroyWindow();
}
m_dlg->Create(CMyDlg::IDD, &m_tabctrl/*CTabCtrl*/);// ASSERT(pWnd->m_hWnd == NULL);

You should remove this code from your constructor. because it will create a dialog with the IDD (resource ID) you are passing. that is why it failed.

see MSDN to know how to create modeless dialog?[^]

You can see the following in the documentation... that

For a modeless dialog box, you must provide your own public constructor in your dialog class.

i don't agree

see the code inside the constructor.

CDialog::CDialog(UINT nIDTemplate, CWnd* pParentWnd)<br />
{<br />
	AFX_ZERO_INIT_OBJECT(CWnd);<br />
<br />
	m_pParentWnd = pParentWnd;<br />
	m_lpszTemplateName = MAKEINTRESOURCE(nIDTemplate);<br />
	m_nIDHelp = nIDTemplate;<br />
}

is only sets the member varaiable.Wont create the dialog

yes once I had went through the code...
for the ease of undestanding I explained it that manner.

when creating a modal dialog, the error occurs at module state handling.

The function get called twice. first on the ctor and Create function

Anyway I dont know more about the same. It would nice informative if you share how a modal dialog asserts on the above scenario

check the code he posted.

in the constructor itself he creates the dialog. I.e

CMyDlg dlg; // Dialog is created in this line itself.

then he calls

dlg.Create(...) the dialog is already created, hence Assertion fails will come and most probably from the function

void AFXAPI AfxHookWindowCreate(CWnd* pWnd)
{
..........
ASSERT(pWnd->m_hWnd == NULL); // only do once
...........
}

So it's not part of CDialog. it's part of CWnd right? then how the creation with template name specified occurs?
