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()
{
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()
{
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()
{
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.

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

During long search operation in MFC applicaton how to add animation CWaitCursor
|
|
|
|

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.

Yes true, But I dont want the normal hour glass, but instead I need some other animation, so...

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.

Can you respond to the WM_SETCURSOR message?

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

Does hcur have global scope?

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?

Please elaborate.

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

Your post is confusing, unclear and clueless ALL at the same time. Anyone attempting to answer you will have a tendency to jab a needle into their eye.
However, to answer your post: If the other application has opened the file in exclusive access mode, you will not be able to even read it. Again, if you do have access to the file, it is not clear from your post if you want to save updates to the same file (depends on if the application that created the file is allowing other applications to perform a write operation on it).
