Displaying the Print Dialog Box

This topic describes sample code that displays a Print dialog box so a user can select options for printing a document. The sample code first initializes a PRINTDLG structure, and then calls the PrintDlg function to display the dialog box.

This example sets the PD_RETURNDC flag in the Flags member of the PRINTDLG structure. This causes PrintDlg to return a device context handle for the selected printer in the hDC member. You can use the handle to render output on the printer.

On input, the sample code sets the hDevMode and hDevNames members to NULL. If the function returns TRUE, these members return handles to DEVMODE and DEVNAMES structures containing the user's input and information about the printer. You can use this information to prepare the output to be sent to the selected printer.

PRINTDLG pd;
HWND hwnd;

// Initialize PRINTDLG
ZeroMemory(&pd, sizeof(PRINTDLG));

pd.lStructSize = sizeof(PRINTDLG);
pd.hwndOwner = hwnd;
pd.hDevMode = NULL; // Don't forget to free or store hDevMode.
pd.hDevNames = NULL; // Don't forget to free or store hDevNames.
pd.Flags = PD_USEDEVMODECOPIESANDCOLLATE | PD_RETURNDC;
pd.nCopies = 1;
pd.nFromPage = 0xFFFF;

pd.nToPage = 0xFFFF;

pd.nMinPage = 1;

pd.nMaxPage = 0xFFFF;

if (PrintDlg(&pd)==TRUE) {

// GDI calls to render output.

// Delete DC when done.
DeleteDC(pd.hDC);
}

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More »
