I need to print some text (using font specified), than print a bitmap, using MFC. I can draw text on bitmap, than print this bitmap, using code below - but I need to print text, and than print bitmap in the bottom. The bitmap must be loaded from file.
CFont j1;
j1.CreateFont(
120, // nHeight
120, // nWidth
0, // nEscapement
0, // nOrientation
FW_NORMAL, // nWeight
FALSE, // bItalic
FALSE, // bUnderline
0, // cStrikeOut
RUSSIAN_CHARSET, // nCharSet
OUT_DEFAULT_PRECIS, // nOutPrecision
CLIP_DEFAULT_PRECIS, // nClipPrecision
DEFAULT_QUALITY, // nQuality
DEFAULT_PITCH | FF_SWISS, // nPitchAndFamily
"Arial"); // lpszFacename // lpszFacename
int w = 600, h = 400;
CClientDC dc(this);
CBitmap bmp;
CDC memdc;
memdc.CreateCompatibleDC(&dc);
bmp.CreateCompatibleBitmap(&dc, w, h);
if (!bmp.Attach(::LoadImage(
::GetModuleHandle(NULL), "D:\\UPM\\BMP\\Login.bmp", IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE))) {
AfxMessageBox(_T("Error loading bitmap!")); return;
}
BITMAP bm;
bmp.GetBitmap(&bm);
auto oldbmp = memdc.SelectObject(bmp);
CFont* pOldFont = memdc.SelectObject(&j1);
//draw on bitmap
///memdc.FillSolidRect(0, 0, w, h, RGB(200, 200, 200));
memdc.SetTextColor(RGB(255, 0, 0));
CRect rc(0, 0, w, h);
memdc.DrawText("qwerty\nrtrtrt\nttttt", &rc, DT_WORDBREAK | DT_EXPANDTABS | DT_CENTER);
///pDC->DrawText(dpu, strRect, DT_WORDBREAK | DT_EXPANDTABS | DT_CENTER);
//dc.BitBlt(0, 0, w, h, &memdc, 0, 0, SRCCOPY);//optional: draw the bitmap on dialog
CPrintDialog pd(false);
if (pd.DoModal() == IDOK)
{
CDC PrintDC;
HDC hdc = pd.GetPrinterDC();
PrintDC.Attach(hdc);
DOCINFO docinfo = { sizeof(docinfo) };
docinfo.lpszDocName = "Print test";
PrintDC.StartDoc(&docinfo);
PrintDC.StartPage();
PrintDC.BitBlt(0, 0, w, h, &memdc, 0, 0, SRCCOPY);
PrintDC.EndPage();
PrintDC.EndDoc();
}
dc.SelectObject(oldbmp);
CClientDC dc(this);
dc.DrawText(...);
...
PrintDC.BitBlt(0, 0, w, h, &memdc, 0, 0, SRCCOPY);
You are drawing text on display's "client DC", then drawing a bitmap on a "printer DC".
Use instead a paint function for everything, and a paint_bitmap function to make things easier.
void paint_bitmap(CDC& dc, CBitmap &bmp, CRect rc)
{
CDC memdc;
memdc.CreateCompatibleDC(&dc);
auto oldbmp = memdc.SelectObject(&bmp);
dc.BitBlt(rc.left, rc.top, rc.Width(), rc.Height(), &memdc, 0, 0, SRCCOPY);
memdc.SelectObject(oldbmp);
}
void paint(CDC& dc)
{
CBitmap bmp;
if (!bmp.Attach(...))...
dc.DrawText(L"text", &rc, ...);
rc.OffsetRect(0, 200);
paint_bitmap(dc, bmp, rc);
}
...
CPrintDialog pd(false);
if (pd.DoModal() == IDOK)
{
HDC hdc = pd.GetPrinterDC();
if (hdc)
{
...
dc.StartPage();
paint(dc); //<- use this for printer or display
dc.EndPage();
}
To print directly to default printer:
CPrintDialog pd(false);
if (pd.GetDefaults() && pd.m_pd.hDC)
{
CDC dc;
dc.Attach(pd.m_pd.hDC);
DOCINFO docinfo = { sizeof(docinfo) };
docinfo.lpszDocName = L"Print test";
dc.StartDoc(&docinfo);
dc.StartPage();
paint(dc);
dc.EndPage();
dc.EndDoc();
}
else
{
MessageBox(L"no default printer...");
}
or if you want a particular printer which you are sure is there, use
HDC hdc = CreateDC(L"WINSPOOL", L"Microsoft Print to PDF", NULL, NULL);
if (hdc)
{
CDC dc;
dc.Attach(hdc);
...
//DeleteDC(hdc); CDC will take care of delete
}
I want to print a bitmap. To avoid printing small bitmap I set CScrollView mode as MM_LOMETRIC with sizes 3830 x 1995. I have created the bitmap and made the bitblt to the screen. There were everythig just like I want on the screen and on the print preview but when I printed the document I've got very bad result.
The same picture on print preview.
It seems to me that printer does not see a bitmap the same way as print preview does.
Pay attantion that the first ractangle puts directly on the DC and memDC puts into it.
Are there any ideas how to fix this mismatch between print previw and the real printing?

When the picture of the woman moves over one of the moving hexagons, a few things happen. I have a sound(police) that is triggered when she touches one of them. The problem is that the sound continues even when she is not on the hexagon even longer. Plus, if she touches the hexagon again the sound is triggered again over the first sound. So now I have a mess of the same sound playing over each other.
I want her to move over a hexagon, the sound is triggered. When she moves off the hexagon the sound instantly stops until she moves over it again.

Try using AudioPlayer instead of AudioSample. It provides isPlaying() which is handy to check if the sound is already playing or not.
e.g.
//at the top
AudioPlayer police;
//in setup()
police = minim.loadFile("PoliceSiren.mp3");
//in draw() instead of police.trigger()
if(!police.isPlaying() || ){
police.play();
}

It sounds like looping is what you're after:

Also checkout mute(),unmute(),isMuted(): perhaps you can keep the sound looping but muted and only unmute when the collision happens
I have been working on the piece of code below in Processing using the sound library Minim, and have been trying to stop the audio recorded into the program from chopping the sound, rendering it somewhat unaudible.
Setup():

I made your code work with databinding, use Platform.runLater() to go back to the GUI thread to update javafx components.
If you want to use ScheduledService here is a basic example:
public class Sandbox extends Application {
public static void main(final String[] args) throws Exception {
launch(args);
}
class MyService extends ScheduledService<List<String>> {
#Override
protected Task<List<String>> createTask() {
final Task<List<String>> voidTask = new Task<List<String>>() {
#Override
protected List<String> call() throws Exception {
List<String> results = new ArrayList<>();
final String memStrLong = Long.toString(Runtime.getRuntime().totalMemory());
results.add(memStrLong);
final String fStrLong = Long.toString(Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory());
results.add(fStrLong);
final String amStrLong = Long.toString(Runtime.getRuntime().maxMemory());
results.add(amStrLong);
return results;
}
};
return voidTask;
}
}
