I design applications with new MFC components like CMFCToolBar and want to design it with High-DPI aware. I provide proper toolbar images for each DPI and I need to tell CMFCToolBar to don't scale images in high DPI modes.

So I need set CMFCToolBar::m_bDontScaleImages variable to TRUE, but this can be done only with static link. With dynamic link linker shows error with unresolved external.

I can't use static link for my projects (it's huge project with many DLLs etc.).

Details (expand)

Visual Studio 2010

1) Make new project (New project - Visual C++ - MFC Application)
In new wizard on second page ensure that "Use MFC in shared DLL" is selected and everything else left at default, then click finish - new app will be generated.
2) Compile application - compiles and links OK.
3) Add this line to mainframe.cpp to CMainFrame::OnCreate method:
CMFCToolBar::m_bDontScaleImages = TRUE;
4) Compile application - linker shows error with unresolved external. This is the problem.
5) Switch application to static link
- project properties - configuration properties - general
- set "Use of MFC" to "Use MFC in a Static Library"
6) Compile application - compiles and links OK (in one EXE).

Can't link MFC app if I use line: CMFCToolBar::m_bDontScaleImages = TRUE; and app is set with shared MFC library link.

App with CMFCToolBar::m_bDontScaleImages = TRUE; line code can be compiled and linked with "shared MFC library" settings.

Thanks Stefan0073:

afxGlobalData.EnableRibbonImageScale(FALSE);

really did the work. It work for non-ribon toolbars too.

We are facing the same problem and it was really a surprise that this is not fixed in SP1.

So I'd really appreciate if someone from Microsoft can comment in which release this this will be fixed.

Thanks,
Ralf

Today I installed VS 2010 SP1 and think, that this is fixed, but I'm surprised, that this is still NOT fixed in VS2010 SP1!

Can anybody tell me, why is this Closed as Fixed, when it's not fixed?

Instead of setting the variable m_bDontScaleImages, just disable ribbon image scaling:

afxGlobalData.EnableRibbonImageScale(FALSE);

this has the very same effect.
