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.

I wrote this code in the button click event, but no change in the run time
I get normal pointer cursor. please advice, I want to display animated cursor.

HCURSOR hcur;
	hcur = ::LoadCursorFromFile((LPCWSTR)"C:\\eglobe.ani");  
	::SetSystemCursor(hcur,OCR_NORMAL);

when I add watch for "hcur" it is null and unused

WriteProfileString()

after choosing and closing the Font Dialog in an SDI appliction, the last choosen Fon must be saved via WriteProfileString() and by the next call
it should be loaded sot that the Font is automatically selected via GetProfileString().

I have the following code:

CString strFaceName;
CString strFontSize;
CString strFontStyle;
CString strFontValue;

CFont *m_cfont = (CFont*) new CFont();

LOGFONTA *m_lf = new LOGFONTA();

int m_nFontSize = 0;

CWinApp* pApp = AfxGetApp();

m_cfdlg.GetCurrentFont(m_lf);

strFaceName = m_cfdlg.GetFaceName();

m_nFontSize = m_cfdlg.GetSize() ;

m_cfont->CreateFont(m_nFontSize, m_lf->lfWidth,m_lf->lfEscapement,m_lf->lfOrientation,
m_lf->lfWeight,m_lf->lfItalic,false,0,1,OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH | FF_SWISS,strFaceName);

itoa(m_nFontSize,(char*)strFontSize.GetString (),10);

pApp->WriteProfileString(strFaceName, strFontSize, strFontStyle);

strFontValue = pApp->GetProfileString(strFaceName, strFontSize, strFontStyle);

as i know WriteProfileString, write in the registry, but this code needs something more to work properly?

Actually it's pretty good (correct sentence:"Come stai? (E la tua famiglia?)").
