Printing text and bitmap using MFC - visual-c++

Question

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
}
