Ok, now my code looks like this:
VERIFY(pMainFrame->m_InitalDlg.Create(CInitialDlg::IDD, NULL));
pMainFrame->m_InitalDlg.ShowWindow(SW_SHOW);
It's still the same thing. Actually now i can't even press the buttons on m_InitialDlg.
This is the dialog's style:
DS_SETFONT | DS_3DLOOK | DS_FIXEDSYS | DS_CONTROL | DS_CENTER | WS_CHILD

Why is WS_CHILD given for a dialog that you want to be popup. . Lol make it WS_POPUP.

Thanks for your help man. It's still not working though  . Have you done this? Are you sure it will eventually work this way?
|
|
|
|

Do i need to call repaint or something anywere? If i set style to popup, it becomes visible when the user presses a button in that area of the main frame( Even though another child window is opened)

Instead of pMainFrame give m_InitialDialog.GetDesktopWindow().
i.e
VERIFY(pMainFrame->m_InitialDlg.Create(CInitialDlg::IDD, m_InitialDialog.GetDesktopWindow()));
I did a small sample and this worked...
static CAboutDlg dlg;
if( dlg.m_hWnd == NULL )
dlg.Create( IDD_ABOUTBOX,dlg.GetDesktopWindow());
dlg.ShowWindow(SW_SHOW);

Can't draw CString string with DrawString(GDI+)
CString str=_T("test string");
FontFamily fontFamily(L"Times New Roman");
Font font(&fontFamily, 24, FontStyleRegular, UnitPixel);
PointF pointF(30.0f, 10.0f);
SolidBrush solidBrush(Color(255, 0, 0, 255));
graphics.DrawString(str.GetBuffer(), -1, &font, pointF, &solidBrush);
|
|
|
|
|
DrawString will take WCHAR* as its first argument, CString::GetBuffer() won't workout. Try using WCHAR* instead str.GetBuffer()
|
|
|
|

There's no need to use GetBuffer, you can simply pass the CString object, if it's the right width. I suspect you're compiling without UNICODE defined, so your CString is actually a CStringA, which does not have a conversion operator to const WCHAR*. It stores byte-oriented national character set characters. GDI+ expects UTF-16 Unicode characters. You need to either store your strings in this format, or convert them when you need to use them.
Unless you want compatibility with Windows 9x, the easiest thing to do is to simply define UNICODE and _UNICODE, or select the 'Unicode' configuration if you already have one. You need to define both macros because the Windows headers use UNICODE while the C run-time uses _UNICODE. This forces all CString objects to be UTF-16 Unicode. You'll have to fix any compile errors you get here, where you've used a string not wrapped in _T().
Slightly more difficult is to store any strings you want to display on screen in the correct format. Here you should consider using CStringW objects (I'm assuming you're using at least MFC 7.0 from Visual Studio .NET 2002, rather than MFC 6.0). You can construct a CStringW from byte-oriented national character set data (char*). You can convert at the point of use if necessary. Using CStringW is slightly more straightforward than trying to use the MultiByteToWideChar API directly.
If explicitly using the wchar_t, WCHAR or CStringW datatypes, you should use the L"" syntax to specify your string literals, rather than _T(). Only use _T() for values that should change format depending on whether _UNICODE is defined.

CPropertySheet properties(_T("вфыавав"), this, 0);//error C2664: 'CPropertySheet::CPropertySheet(UINT,CWnd *,UINT)' : cannot convert parameter 1 from 'const wchar_t [13]' to 'UINT'
??? but CPropertySheet have constructor with LPCTSTR as the 1st parameter
explicit CPropertySheet(
LPCTSTR pszCaption,
CWnd* pParentWnd = NULL,
UINT iSelectPage = 0
);
|
|
|
|
|
Based on your other question I'd say you probably have _UNICODE defined (which causes _T("") to become L"") but not UNICODE, which causes LPCTSTR to become LPCWSTR rather than LPCSTR.

Hello, I want to add a new font to my project but I dont know how?
I downloaded a program and made my font MyFont.ftw and I want to add it,how can I add it to my project and use it in the Static Text.

Not sure what you mean but you can change the Static font like this
CFont *pNewFont = new CFont;
LOGFONT lf = { 0 };
lf.lfHeight = -12;
lf.lfWeight = FW_LIGHT;
_tcscpy(lf.lfFaceName,_T("Tahoma"));
pNewFont->CreateFontIndirect(&lf);
//After the Static control is created
//Typically in InitDialog functions
GetDlgItem(IDC_STATIC_TEXT)->SetFont(pNewFont);
//Don't forget to Delete the font in OnDestroy
delete pNewFont;
Hope it helps

I am facing the problem in printing document. I haev craeted the WIn32 Apllicatio and then in WM_PAINT I amdraing the ellipse. Now I want to printwhatever I see on client area.
I tried with it but was giving whole scrren aftyer printing with reduced size.
I need it in Win32.

I insert lines to this code but check your code i used PrintDlg and
use from pd.hDC instead CreateDC and i cant find a ellipse in your code
but when you run this code you see a ellipse almost in center

I have the ellipse created on WM_PAINT.
case WM_PAINT:
hdc = BeginPaint(hWnd, &ps);
// TODO: Add any drawing code here...
::Ellipse(hdc,100,100,500,500);
RECT rect;
rect.left = 200;
rect.top = 200;
rect.right = 400;
rect.bottom = 400;
::DrawText(hdc,_T("I am the best"),(int)strlen(_T("I am the best")),&rect,DT_CENTER);
EndPaint(hWnd, &ps);
break;
and on the menu click:
case IDM_MENU1:
hClientDC = GetDC(hWnd);
PrintSelected(hWnd,hClientDC);
break;
I don't want directly to draw ont print dc. First I want to take the handel of my Client DC such taht whatever is drawn on the client are shouldbe printed on page

Thats cause the printers resolution is more than Screens resolution
heres some sample code
CDC prtDC;
CPrintInfo printInfo;
CSize size;
DOCINFO di;
CSize paper_size;
int xLogPPI = 0;
int yLogPPI = 0;
if( AfxGetApp()->GetPrinterDeviceDefaults(&printInfo.m_pPD->m_pd) )
{
HDC hDC = printInfo.m_pPD->m_pd.hDC;
if (hDC == NULL)
hDC = printInfo.m_pPD->CreatePrinterDC();
if(hDC !=NULL)
{
prtDC.Attach(hDC);
paper_size.cx = prtDC.GetDeviceCaps(HORZSIZE);
paper_size.cy = prtDC.GetDeviceCaps(VERTSIZE);
xLogPPI = prtDC.GetDeviceCaps(LOGPIXELSX);
yLogPPI = prtDC.GetDeviceCaps(LOGPIXELSY);
}
else
{
AfxMessageBox("Can not find printer. Please check installed/default printers.");
return ;
}
}
int scr_xLogPPI = pDC->GetDeviceCaps(LOGPIXELSX);
int scr_yLogPPI = pDC->GetDeviceCaps(LOGPIXELSY);
int paper_width = (int) ((double) paper_size.cx * (double) xLogPPI / 25.4);
int paper_height = (int) ((double) paper_size.cy * (double) yLogPPI / 25.4);
double ratio_x = (double) xLogPPI / (double) scr_xLogPPI;
double ratio_y = (double) yLogPPI / (double) scr_yLogPPI;
CFont *pPrnFont = new CFont();
LOGFONT lf = {0};
lf.lfHeight = -14 * ratio_x;
lf.lfWeight = FW_NORMAL;
_tcscpy(lf.lfFaceName,"Times new roman");
pPrnFont->CreateFontIndirect(&lf);
..
..
..
you need to multiply everything with ratio_x and ratio_y so that everythings printed like it is diplayed on the screen
Hope it Helps

Ok Ganesh listen up, The printer resolution is far more than screen's resolution.
So you need to calculate the number of times Printer resolution is greater than Screen's
So get printers Resolution use
int xPrnRes = GetDeviceCaps(hPrinterDC,LOGPIXELSX);
int yPrnRes = GetDeviceCaps(hPrinterDC,LOGPIXELSY);
Get Screens Res
int xScrnRes = GetDeviceCaps(hScreenDC,LOGPIXELSX);
int yScrnRes = GetDeviceCaps(hScreenDC,LOGPIXELSY);
Get Ratio
double ratio_x = (double)xPrnRes/(double)xScrnRes;
double ratio_y = (double)yPrnRes/(double)yScrnRes;
ok so if you have an image of say 100x100 px on screen and you want to print it the destination image will be of 100*ratio_x and 100*ratio_y
so instead of using BitBlt you have to use StretchBlt to stretch the Bitmap
