It's not. Use GetWindowText() instead. Depending on the style of combobox used, GetLBText() will not always get the text in the edit control.

ok my problem is that i want this code to output some specific points like iLipBottomX the coordinate value.

but this code actually detects and draws out the picture.

From this can u deduce wat variable must i printf to get the result i want?

The SMouthFeature structure contain these variable

bool bMouthFound; // Mouth finding flag
bool bSplMouthFound; // Mouth spline finding flag
HSPLINE hSpl_mouth; // Mouth spline handle
bool bSplLipTopFound; // Top lip spline finding flag
HSPLINE hSpl_lip_top; // Top lip spline handle
bool bSplLipBottomFound; // Bottom lip spline finding flag
HSPLINE hSpl_lip_bottom; // Bottom lip spline handle
bool bLipTopFound; // Top lip point finding flag
int iLipTopX; // x coordinate of the top lip point
int iLipTopY; // y coordinate of the top lip point
bool bMouthCenterFound; // Mouth center finding flag
int iMouthCenterX; // x coordinate of the mouth center
int iMouthCenterY; // y coordinate of the mouth center
bool bLipBottomFound; // Bottom lip point finding flag
int iLipBottomX; // x coordinate of the bottom lip point
int iLipBottomY; // y coordinate of the bottom lip point
bool bMouthLeftCornerFound; // Mouth left corner finding flag
int iLeftCornerX; // x coordinate of the mouth left corner
int iLeftCornerY; // y

u understand or do u need further info i can provide

Hi
in my application i try to set an printer fonts.From msdn i took this example how it do.

CHOOSEFONT cf;
LOGFONT lf;
HFONT hfont;

// Initialize members of the CHOOSEFONT structure.

cf.lStructSize = sizeof(CHOOSEFONT);
cf.hwndOwner = (HWND)NULL;
cf.hDC = (HDC)NULL;
cf.lpLogFont = &lf;
cf.iPointSize = 0;
cf.Flags = CF_SCREENFONTS;
cf.rgbColors = RGB(0,0,0);
cf.lCustData = 0L;
cf.lpfnHook = (LPCFHOOKPROC)NULL;
cf.lpTemplateName = (LPSTR)NULL;
cf.hInstance = (HINSTANCE) NULL;
cf.lpszStyle = (LPSTR)NULL;
cf.nFontType = SCREEN_FONTTYPE;
cf.nSizeMin = 0;
cf.nSizeMax = 0;

// Display the CHOOSEFONT common-dialog box.

ChooseFont(&cf);

// Create a logical font based on the user's
// selection and return a handle identifying
// that font.

hfont = CreateFontIndirect(cf.lpLogFont);

//After this i has hfont variable vary by NULL,and try to
//select it into printer device context m_hPrinterDC
//(this variable was initialized early and
//also have a proper value,because of when i output text
//on one or do any other acts all work fine.

//In this step i try to select created logical font into dc

HGDIOBJ hf1 = SelectObject(m_hPrinterDC,&hfont);

//This function return NULL,what meant an error.
Where is my fault?????

Also i try to change some params in cf structure like this:

cf.hDC = m_hPrinterDC;
cf.Flags = CF_PRINTERFONTS;
cf.nFontType = PRINTER_FONTTYPE;

But result exactly same.

Thanks.

How to create hidden Dialog Window ?

vgrigor25-Feb-04 2:42

I create followng:

CDialog dlg;
dlg.Create(IDD.pWnd);

dlg appears, but I neeed to hide it,
I made following:
but no resilt,
how to do it?

<br />
int cWaitDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)<br />
{<br />
	//remove VS_VISIBLE style<br />
/**/	<br />
<br />
	this->ModifyStyle(WS_VISIBLE,0,0);<br />
<br />
	lpCreateStruct->style |= WS_VISIBLE;<br />
	lpCreateStruct->style -= WS_VISIBLE;<br />
<br />
	this->ShowWindow(SW_HIDE);<br />
<br />
	if (__super::OnCreate(lpCreateStruct) == -1)<br />
		return -1;<br />
<br />
		<br />
	// TODO:  Add your specialized creation code here<br />
<br />
	return 0;<br />
}<br />
<br />
BOOL cWaitDlg::PreCreateWindow(CREATESTRUCT& cs)<br />
{<br />
	// TODO: Add your specialized code here and/or call the base class<br />
/**/	<br />
	cs.style |= WS_VISIBLE;<br />
	cs.style -= WS_VISIBLE;<br />
<br />
	int j = cs.style & WS_VISIBLE;<br />
<br />
	return __super::PreCreateWindow(cs);<br />
}<br />

What are you trying to do here? If you want the window to be hidden, why not just remove the WS_VISIBLE style from the dialog template? Otherwise, the code you have makes no sense. Note this may not work as CDialog::OnInitDialog() "shows" the window explicitly.

Removing style not prevent from appearing,
so that even I hide by comman Window will flick one moment,
and that is problem.

Need to to appear at any.

Derive a class from CDialog using the dialog template. In that class' constructor, call Create(IDD).

// create the dialog
CMyDialog *pDlg;
...
// now show it
pDlg->ShowWindow(SW_SHOW);

Why create a dialog any way when its going to be hidden? why not create a window using CreateWindow api???
or derive a class from CWnd class and then create it so that you have the power of message mapping of MFC
