Not really sure what you're after, but there's a chance that a namespace would satisfy your needs. Have a look here[^].

Hi,
Yes it would but namespaces works in C++ and many libraries are in plain C.
Best regards, Mauro.

if you code in C++, there's no problem... you can import C functions inside it then
what do you think the standard C++ library does with the C runtime functions into the std:: namespace ?

Each C source files in theora generates a .obj file with the possible conflicting public symbols. Encapsulating inside a C++ object doesn't hide public symbols from original theora compiled object files.
Code is opensource so I can make things like changing function names but I wish to avoid that in order to make updates easily when there are new versions available.
Greetings,
Mauro

you don't get it.
process in 2 steps.
firstly, generate a library which will present the theora in your namespace.
then, use this "new" library, which won't generate name duplicates anymore, due to the namespace...

Thanks Toxcct 4 answering.
Can you explain me more detailed?
Imagine I have a C function named myfunc in test1.c
Then test1.lib will contain the module test1.obj that contains the _myfunc public symbol.
On the other side, another function with the same name but in test2.lib
When I link the app with test1.lib and test2.lib the linker gives an error in test2.lib(test2.obj) because _myfunc is already defined in test1.lib(test1.obj)
I didn't find to hide test1.obj from the visibility of test2.obj, no matters if it is inside a .lib
Best regards,
Mauro.

Hi everybody,
I try to create a modeless dialog in the client area of a MDI application. It should display some data form the app class (not the document). When I create the dialog:
pmyDlg = new CmyDialog;
pmyDlg->Create(IDD_DIALOG_mydlg)
pmyDlg->ShowWindow(SW_SHOW)
it always appear on top of the application, not in the client area of the child frame. I tried things like pmyDlg->Create(IDD_DIALOG_mydlg, theApp.m_pMainWnd) to set a parent for this dialog but it was alway dragable over the whole desktop and was not restricted to the client area.
Can someone send me a hint?
Many thanks.
Cheers,
Frank.

did you have a look at this[^] ?

yes, but it doesn't help me because Nishant Sivakumar suggest to use the desktop window as a parent for the modeless dialog. When I do this, the modeless dialog is even more independent of my application.
What I want is a modeless dialog, which behaves like a MDIView but without the overhead of the document. It should be moveable only inside the client area of the application and not on the whole desktop.

Subclass your childview[of MDI] and create a child[WS_CHILD] dialog on it.

yuck.

double yuck.
but I'm a good sport.
Can't you create the modeless dialog with the MainFrame as a WS_CHILD of the main frame ? or something similar ?
I think I remember that you can set of the dialog style to do this.

ok, that was bad! 
|
|
|
|

I also thought that it should be possible to set WS_CHILD style but haven't found a way to do this.

Do you want the MDIFrame window to be the parent or do you want to place the dialog in a
MDIChild frame?
Either way, the dialog needs to be a child and you need to specify the parent in the Create()
call.
You can set the child style in the resource editor, properties, style.

I set the style to child in the dialog editor properties and did the following during the creation of the dialog:
CMainFrame* pFrame = (CMainFrame*)GetMainWnd();
CChildFrame* pChild = (CChildFrame*)pFrame->GetActiveFrame();
CmyDlg* pDlg = new CmyDlg;
pDlg->Create(IDD_DIALOG_myDlg, pChild->GetParent());
pDlg->ShowWindow(SW_SHOW);
This is almost what I wanted but it shows some weird behaviour. When a region of the dialog is covered by another child window this region shows still the part of the child window even if I drag the dialog to another place. It only restores the correct dialog, when I resize the dialog. Is there somewhere a flag like redraw or something?
Many thanks  ,
Frank.

hmm I'm not sure if there's different invalidation with MDI windows (which differ from other
windows because they're controlled by an "MDICLIENT" class window).
I have a feeling it's due to activation issues. Mixing a non-MDI child window in a MDI client
window isn't necessarily going to work properly.
I still think it's much easier to make the dialog a client window of a CMDIChildWnd frame. There
shouldn't be any issues then.

Here's some more info: Using the Multiple Document Interface[^]
As you can see in the Window Procedure sections, the MDI windows use different default window
procs so they can/will behave differently than normal parent/child windows.

You could do something like:
BOOL CModelessDlg::OnInitDialog()
{
CDialog::OnInitDialog();
CRect rc;
GetWindowRect(rc);
m_lWidth = rc.Width();
m_lHeight = rc.Height();
AfxGetMainWnd()->GetWindowRect(m_rcParent);
return TRUE;
}
void CModelessDlg::OnMoving(UINT fwSide, LPRECT pRect)
{
CDialog::OnMoving(fwSide, pRect);
pRect->left = min(pRect->left, m_rcParent.right - m_lWidth);
pRect->left = max(pRect->left, m_rcParent.left);
pRect->top = min(pRect->top, m_rcParent.bottom - m_lHeight);
pRect->top = max(pRect->top, m_rcParent.top);
pRect->right = min(pRect->right, m_rcParent.right);
pRect->right = max(pRect->right, m_rcParent.left + m_lWidth);
pRect->bottom = min(pRect->bottom, m_rcParent.bottom);
pRect->bottom = max(pRect->bottom, m_rcParent.top + m_lHeight);
}It works regardless of whether WS_POPUP or WS_CHILD is used. A parent can be specified or not.

Hi,
after playing with some LockWindowUpdate / UnlockWindowUpdate and SetRedraw(FALSE) / SetRedraw()
i have a problem with a view, a grid on this view disappears after drawing.
I removed all LockWindowUpdates,Unlock,SetRedraws and the problem is still there.
I added a this->RedrawWindow(); at the end of the initialisation but this line
erases the hole view,the grid and all other components ( it will be redrawn if the MainForm will be minimized/restored)
It seems as the Invalidations are working inverted 
big thanks in advance
-- modified at 7:55 Tuesday 20th March, 2007
I removed the line where i add the row to the grid and all is ok.
I re-insert the line and the Grid becomes invisible(not drawn)
But i have nothing changed at the grid, at the moment i have so strange problems
The same with a class which i allocate in a thread and delete at the end of the function.
If i set 0 to a variable, the debugheap is corrupted at the destruction of the element.
if i dont set a value to the variable, i don't get an error...

I resolved the problem partially.
I put a Grid->RedrawWindow(NULL, NULL, RDW_INVALIDATE | RDW_UPDATENOW | RDW_ERASE | RDW_FRAME);
into the EraseBackground Handler.
But it's not the reason of the problem.
If i put the view directly into a frame( not into a TabWnd of another view ) it works also without errors.

Hello,
Is it safe to use:
CDC memDC;
memDC.CreateCompatibleDC(pDC);
CBitmap *m_pOld = memDC.SelectObject(&some_bitmap1);
memDC.SelectObject(&some_bitmap2);
memDC.SelectObject(&some_bitmap3);
memDC.SelectObject(&some_bitmap4);
....
memDC.SelectObject(m_pOld);
memDC.DeleteDC;
or I should use SelectObject(m_pOld)/DeleteDC() after each SelectObject(&some_bitmapX)??

No.
