If the edit control is always read-only, why not just make it a static control?

Are you redefining a CCriticalSection object somewhere in your own code ?

Are you including afxmt.h? Have you read this?

I recently encountered this ambiguous symbol issue and found a solution. Posting here in this old thread for reference.

I had the same issue in a project where I needed to include both <afxmt.h> and <atlsync.h>. They each have a similar set of concurrency classes with the same names -- but for a given class some of the member functions are distinct.

In Visual Studio 2022 build 17.4.3 with the latest Windows 10 SDK (and perhaps in older IDEs and SDKs), you can reference classes from both of these headers without ambiguity, so long as you:

1) Include afxmt.h BEFORE including atlsync.h, e.g.

#include <afxmt.h>
#include <atlsync.h>

2) Do NOT specify using namespace ATL

3) To reference a class in atlsync.h, preface the class name with ATL::, e.g. ATL::CEvent or ATL::CSemaphore. If you do not add this ATL:: namespace preface, the class will be referenced from afxmt.h.

If you don't want to use the CCriticalSection class from MFC, try using the Win32 synchronization functions:

EnterCriticalSection[^]
LeaveCriticalSection[^]

Target compilation of VC compiler [modified]

Hi,

I have downloaded an app from the below link and using it, it works fine.

Neat Tooltip for ComboBox[^]

I create a new MFC dialog based application in VS2008, and add 2 files from the prev project to this new project, the tool tip functionality does not work.

I guess the issue is with the target OS for compilation.

In VS2008, the target compilation is Vista, 0x0600. - the tool tips dont work.
In the prev project the target compilation is 0x0500. - the tool tips work here.

In my new project, if i change explicitly the target OS to 0x0500, the tool tips work.

I dont know what is the problem.

Any help will be great. I am using IE 7.

Thanks,
Saleem

There is a bug in the source code of the article. The author is incorrectly retrieving the NONCLIENTMETRICS Structure[^] lfStatusFont member.

The code in the constructor:

CTTComboBox::CTTComboBox()
{
	// Using system tool-tip font for the tool-tip window
	NONCLIENTMETRICS ncm;
	ncm.cbSize = sizeof(NONCLIENTMETRICS);
	SystemParametersInfo(SPI_GETNONCLIENTMETRICS, 0, &ncm, 0);
	if (m_font.m_hObject == NULL)
		m_font.CreateFontIndirect(&ncm.lfStatusFont);
.....
}

should be changed to be changed to:

CTTComboBox::CTTComboBox()
{
	// Using system tool-tip font for the tool-tip window
	NONCLIENTMETRICS ncm = {0};
	ncm.cbSize = sizeof(NONCLIENTMETRICS);
	SystemParametersInfo(SPI_GETNONCLIENTMETRICS,sizeof(NONCLIENTMETRICS), &ncm, 0);
	if (m_font.m_hObject == NULL)
		m_font.CreateFontIndirect(&ncm.lfStatusFont);

or perhaps...

CTTComboBox::CTTComboBox()
{
	// Using system tool-tip font for the tool-tip window
	NONCLIENTMETRICS ncm = {0};
	ncm.cbSize = sizeof(NONCLIENTMETRICS);
	SystemParametersInfo(SPI_GETICONTITLELOGFONT,0,&ncm.lfStatusFont,0);
	if (m_font.m_hObject == NULL)
		m_font.CreateFontIndirect(&ncm.lfStatusFont);
...

Hi David,

Thanks for the inputs, this works.

On secound thoughts I was wondering, can we do this ?
ncm.cbSize = sizeof(LOGFONT);
Will this be more correct?

Also, why was the previous code working in the XP targetted OS, but not in Vista targetted OS?

Thanks,
Saleem

You failed to mention which of my recommendations you decided to use.

If you are using the SPI_GETNONCLIENTMETRICS action then set both the cbSize member and the uiParam function parameter to sizeof(NONCLIENTMETRICS)

If you are using the SPI_GETICONTITLELOGFONT action uiParam function parameter specifies the size of a LOGFONT structure.

Md Saleem Navalur wrote:

Apparently when WINVER is <= 0x0500 SystemParametersInfo does not check the size of the buffer you pass in the uiParam parameter.

Everything is clearly explained (with an example and everything) in the documentation[^]. Basically, you just create an instance of the class at the begining of your lenghty function and it will be destroyed when the function exits.

If you've globally set an animated wait cursor then I guess that will be displayed instead of the hour glass. Also you can try LoadCursorFromFile.
