Someone else already suggested CXImage, but I think FreeImage does a better job of resizing (resized image is MUCH nicer than the same result from CXImage) to fit your window if you need to do that.

FreeImage is available on SourceForge.

Window Minimization problem

Hi,

i am using ShellExecuteEx function in an Embeded VC++(MFC Based) to run other application(not MFC) but its Window not get

Minimized though i am passing ShExecInfo.nShow = SW_MINIMIZE parameter. My Code is:
BOOL CSBCApp::InitInstance()
{
CMainFrame* pFrame = new CMainFrame;
m_pMainWnd = pFrame;
pFrame->LoadFrame(IDR_MAINFRAME, WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE, NULL, NULL);

SHELLEXECUTEINFO ShExecInfo = {0};
ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
ShExecInfo.hwnd = NULL;
ShExecInfo.lpVerb = NULL;
ShExecInfo.lpFile = _T("Disk\\MyTest.exe");
ShExecInfo.lpParameters = _T("");
ShExecInfo.lpDirectory = NULL;
ShExecInfo.nShow = SW_MINIMIZE;
ShExecInfo.hInstApp = NULL;
bool ReturnType=ShellExecuteEx(&ShExecInfo);
// The one and only window has been initialized, so show and update it.
pFrame->ShowWindow(m_nCmdShow);
pFrame->UpdateWindow();
return TRUE;
}

Warm Regards,

Use SW_SHOWMINIMIZED instead.

Yes. I overseen WinCE in your original post.

With available options for ShowWindow on WinCE it doesn't seem possible.

Only the following are supported in WinCE. SW_SHOW, SW_HIDE, SW_SHOWNORMAL, SW_SHOWNA
If your requirement is to create a new window but to retain the topmost state of your current window, then create the new window with SW_SHOWNA as the nCmdShow parameter to ShowWindow().

you specified the window to minimize
ShExecInfo.nShow = SW_MINIMIZE;

you are again specifying the window to show with m_nCmdShow
pFrame->ShowWindow(m_nCmdShow);

it depends on m_nCmdShow. comment Show and UpdateWindow functions. it may work.

pFrame->ShowWindow(m_nCmdShow);
This function is for Main MFC Application.

I am using ShellExecuteEx() fuction to run an other Application(not MFC,.exe file) which get minimize at StartUp.Therefore ShExecInfo.nShow = SW_MINIMIZE;
is used.

hi,
i got LNK2001 errors.
I created a sample class in flashplayer7 and in that class i created pointer instances of some Directshow interfaces like IMediaControl etc....
When i tried to access the functions from the interfaces it is showing the below linker errors.

error LNK2001: unresolved external symbol "public: __thiscall CFlashPlayback::CFlashPlayback(void)" (??0CFlashPlayback@@QAE@XZ)

You forgot to provide defintion for constructor you declared.

It seems that m_hWnd is declared twice in same namespace.

Printer DC

Hi,

I have to print images from my application.
For doing this, I created a Printer DC and the images is painted using 'StretchDIBits'.
Now the printing is OK.
The problem is of the sheet size.

How can i change the print size according to the different sheet sizes supported by the specified printer?

Please help.

Regards,
Kumar

For print you can use also of PrintDlg and also see this structure DEVMODE on MSDN

Hi,

Actually i want to know that, whether the printer DC is to be resized according to the paper sizes.

If yes, how can i change the size?

Me already checked with the following code

for( int nIndex = 0; nIndex < nNumPapers; nIndex++ )
{
CString csPaperSize = _T( pPaperNames ); /* Got from GetDeviceCapabilities */
memcpy( pDevModeOutput->dmFormName, csPaperSize.GetBuffer(csPaperSize.GetLength()), 32) ;
HDC hTempHandle;
pDevModeOutput->dmFields |= DM_FORMNAME;
CString csTemp( _T( "" ));

hTempHandle = ResetDC( hDc, pDevModeOutput );
nPixelX = GetDeviceCaps( hDc, HORZRES );
nPixelY = GetDeviceCaps( hDc, VERTRES );

csTemp.Format( _T( "%s : %d, %d" ), pDevModeOutput->dmFormName, nPixelX, nPixelY );

AfxMessageBox( csTemp );
}

but the nPixelX, nPixelY always getting the same for all paper sizes

Did you see DEVMODE ? here[^] (dmPaperSize )

Hi,

The way I change the paper size is given below

pDevModeOutput->dmPaperSize = 0; // It should be set to zero if paper length and width are given seperately
pDevModeOutput->dmPaperLength = pPaperSizes[nSelection].y; // 2970 in case A4
pDevModeOutput->dmPaperWidth = pPaperSizes[nSelection].x; // 2100 in case A4

CString csPaperSize = _T( "" );
memcpy( pDevModeOutput->dmFormName, csPaperSize.GetBuffer(csPaperSize.GetLength()), 32) ;
pDevModeOutput->dmPrintQuality = -1;
pDevModeOutput->dmYResolution = 0;
//pDevModeOutput->dmScale = 90;
pDevModeOutput->dmFields = DM_PAPERSIZE |
DM_PAPERLENGTH |
DM_PAPERWIDTH |
DM_FORMNAME |
DM_PRINTQUALITY |
DM_YRESOLUTION; // DM_SCALE;
// To get the Devmode structure filled
if( !DocumentProperties( NULL, // handle to parent window
hHandle, // handle to printer object
csPrinterName.GetBuffer(csPrinterName.GetLength()+1), // device name
pDevModeOutput, // modified device mode
0, // original device mode
DM_IN_BUFFER// mode options
))
{
return;
}

hDc = CreateDC( NULL, csPrinterName.operator LPCTSTR(), NULL, pDevModeOutput );

nDPIX = GetDeviceCaps( hDc, LOGPIXELSX );
nDPIY = GetDeviceCaps( hDc, LOGPIXELSY );

Actually I don't know the procedure that how to change the paper size. I think some mistakes are there in my code or something is missing. I have to draw a rectangle that is fit into the specified paper size.

Please reply.

szPrintablePixelsMax.cx= ::GetDeviceCaps (hPrinterDC, HORZRES);
szPrintablePixelsMax.cy= ::GetDeviceCaps (hPrinterDC, VERTRES);
szPrintableArea.cx	= ::GetDeviceCaps (hPrinterDC, HORZSIZE);

Me already tried the below code

szPrintablePixelsMax.cx= ::GetDeviceCaps (hPrinterDC, HORZRES);
szPrintablePixelsMax.cy= ::GetDeviceCaps (hPrinterDC, VERTRES);

it always returns the same value for all sheet sizes.
