Members

lStructSize

Type: DWORD

The structure size, in bytes.

hwndOwner

Type: HWND

A handle to the window that owns the property sheet. This member must be a valid window handle; it cannot be NULL.

hDevMode

Type: HGLOBAL

A handle to a movable global memory object that contains a DEVMODE structure. If hDevMode is not NULL on input, you must allocate a movable block of memory for the DEVMODE structure and initialize its members. The PrintDlgEx function uses the input data to initialize the controls in the property sheet. When PrintDlgEx returns, the DEVMODE members indicate the user's input.

If hDevMode is NULL on input, PrintDlgEx allocates memory for the DEVMODE structure, initializes its members to indicate the user's input, and returns a handle that identifies it.

For more information about the hDevMode and hDevNames members, see the Remarks section at the end of this topic.

hDevNames

Type: HGLOBAL

A handle to a movable global memory object that contains a DEVNAMES structure. If hDevNames is not NULL on input, you must allocate a movable block of memory for the DEVNAMES structure and initialize its members. The PrintDlgEx function uses the input data to initialize the controls in the property sheet. When PrintDlgEx returns, the DEVNAMES members contain information for the printer chosen by the user. You can use this information to create a device context or an information context.

The hDevNames member can be NULL, in which case, PrintDlgEx allocates memory for the DEVNAMES structure, initializes its members to indicate the user's input, and returns a handle that identifies it.

For more information about the hDevMode and hDevNames members, see the Remarks section at the end of this topic.

hDC

Type: HDC

A handle to a device context or an information context, depending on whether the Flags member specifies the PD_RETURNDC or PC_RETURNIC flag. If neither flag is specified, the value of this member is undefined. If both flags are specified, PD_RETURNDC has priority.

Flags

Type: DWORD

A set of bit flags that you can use to initialize the Print property sheet. When the PrintDlgEx function returns, it sets these flags to indicate the user's input. This member can be one or more of the following values.

To ensure that PrintDlg or PrintDlgEx returns the correct values in the dmCopies and dmCollate members of the DEVMODE structure, set PD_RETURNDC = TRUE and PD_USEDEVMODECOPIESANDCOLLATE = TRUE. In so doing, the nCopies member of the PRINTDLG structure is always 1 and PD_COLLATE is always FALSE.

To ensure that PrintDlg or PrintDlgEx returns the correct values in nCopies and PD_COLLATE, set PD_RETURNDC = TRUE and PD_USEDEVMODECOPIESANDCOLLATE = FALSE. In so doing, dmCopies is always 1 and dmCollate is always FALSE.

Starting with Windows Vista, when you call PrintDlg or PrintDlgEx with PD_RETURNDC set to TRUE and PD_USEDEVMODECOPIESANDCOLLATE set to FALSE, the PrintDlg or PrintDlgEx function sets the number of copies in the nCopies member of the PRINTDLG structure, and it sets the number of copies in the structure represented by the hDC member of the PRINTDLG structure.

When making calls to GDI, you must ignore the value of nCopies, consider the value as 1, and use the returned hDC to avoid printing duplicate copies.

ValueMeaning
PD_ALLPAGES
0x00000000

The default flag that indicates that the All radio button is initially selected. This flag is used as a placeholder to indicate that the PD_PAGENUMS, PD_SELECTION, and PD_CURRENTPAGE flags are not specified.

PD_COLLATE
0x00000010

If this flag is set, the Collate check box is selected.

If this flag is set when the PrintDlgEx function returns, the application must simulate collation of multiple copies. For more information, see the description of the PD_USEDEVMODECOPIESANDCOLLATE flag.

See PD_NOPAGENUMS.

PD_CURRENTPAGE
0x00400000

If this flag is set, the Current Page radio button is selected. If none of the PD_PAGENUMS, PD_SELECTION, or PD_CURRENTPAGE flags is set, the All radio button is selected.

PD_DISABLEPRINTTOFILE
0x00080000

Disables the Print to File check box.

PD_ENABLEPRINTTEMPLATE
0x00004000

Indicates that the hInstance and lpPrintTemplateName members specify a replacement for the default dialog box template in the lower portion of the General page. The default template contains controls similar to those of the Print dialog box. The system uses the specified template to create a window that is a child of the General page.

PD_ENABLEPRINTTEMPLATEHANDLE
0x00010000

Indicates that the hInstance member identifies a data block that contains a preloaded dialog box template. This template replaces the default dialog box template in the lower portion of the General page. The system uses the specified template to create a window that is a child of the General page. The system ignores the lpPrintTemplateName member if this flag is specified.

PD_EXCLUSIONFLAGS
0x01000000

Indicates that the ExclusionFlags member identifies items to be excluded from the printer driver property pages. If this flag is not set, items will be excluded by default from the printer driver property pages. The exclusions prevent the duplication of items among the General page, any application-specified pages, and the printer driver pages.

PD_HIDEPRINTTOFILE
0x00100000

Hides the Print to File check box.

PD_NOCURRENTPAGE
0x00800000

Disables the Current Page radio button.

PD_NOPAGENUMS
0x00000008

Disables the Pages radio button and the associated edit controls. Also, it causes the Collate check box to appear in the dialog.

PD_NOSELECTION
0x00000004

Disables the Selection radio button.

PD_NOWARNING
0x00000080

Prevents the warning message from being displayed when an error occurs.

PD_PAGENUMS
0x00000002

If this flag is set, the Pages radio button is selected. If none of the PD_PAGENUMS, PD_SELECTION, or PD_CURRENTPAGE flags is set, the All radio button is selected. If this flag is set when the PrintDlgEx function returns, the lpPageRanges member indicates the page ranges specified by the user.

PD_PRINTTOFILE
0x00000020

If this flag is set, the Print to File check box is selected. If this flag is set when PrintDlgEx returns, the offset indicated by the wOutputOffset member of the DEVNAMES structure contains the string "FILE:". When you call the StartDoc function to start the printing operation, specify this "FILE:" string in the lpszOutput member of the DOCINFO structure. Specifying this string causes the print subsystem to query the user for the name of the output file.

PD_RETURNDC
0x00000100

Causes PrintDlgEx to return a device context matching the selections the user made in the property sheet. The device context is returned in hDC.

PD_RETURNDEFAULT
0x00000400

If this flag is set, the PrintDlgEx function does not display the property sheet. Instead, it sets the hDevNames and hDevMode members to handles to DEVNAMES and DEVMODE structures that are initialized for the system default printer. Both hDevNames and hDevMode must be NULL, or PrintDlgEx returns an error.

PD_RETURNIC
0x00000200

Similar to the PD_RETURNDC flag, except this flag returns an information context rather than a device context. If neither PD_RETURNDC nor PD_RETURNIC is specified, hDC is undefined on output.

PD_SELECTION
0x00000001

If this flag is set, the Selection radio button is selected. If none of the PD_PAGENUMS, PD_SELECTION, or PD_CURRENTPAGE flags is set, the All radio button is selected.

PD_USEDEVMODECOPIES
0x00040000

Same as PD_USEDEVMODECOPIESANDCOLLATE.

PD_USEDEVMODECOPIESANDCOLLATE
0x00040000

This flag indicates whether your application supports multiple copies and collation. Set this flag on input to indicate that your application does not support multiple copies and collation. In this case, the nCopies member of the PRINTDLGEX structure always returns 1, and PD_COLLATE is never set in the Flags member.

If this flag is not set, the application is responsible for printing and collating multiple copies. In this case, the nCopies member of the PRINTDLGEX structure indicates the number of copies the user wants to print, and the PD_COLLATE flag in the Flags member indicates whether the user wants collation.

Regardless of whether this flag is set, an application can determine from nCopies and PD_COLLATE how many copies to render and whether to print them collated.

If this flag is set and the printer driver does not support multiple copies, the Copies edit control is disabled. Similarly, if this flag is set and the printer driver does not support collation, the Collate check box is disabled.

The dmCopies and dmCollate members of the DEVMODE structure contain the copies and collate information used by the printer driver. If this flag is set and the printer driver supports multiple copies, the dmCopies member indicates the number of copies requested by the user. If this flag is set and the printer driver supports collation, the dmCollate member of the DEVMODE structure indicates whether the user wants collation. If this flag is not set, the dmCopies member always returns 1, and the dmCollate member is always zero.

In Windows versions prior to Windows Vista, if this flag is not set by the calling application and the dmCopies member of the DEVMODE structure is greater than 1, use that value for the number of copies; otherwise, use the value of the nCopies member of the PRINTDLGEX structure.

PD_USELARGETEMPLATE
0x10000000

Forces the property sheet to use a large template for the General page. The larger template provides more space for applications that specify a custom template for the lower portion of the General page.

 

Flags2

Type: DWORD

Reserved. Must be zero.
ExclusionFlags

Type: DWORD

A set of bit flags that can exclude items from the printer driver property pages in the Print property sheet. This value is used only if the PD_EXCLUSIONFLAGS flag is set in the Flags member. Exclusion flags should be used only if the item to be excluded will be included on either the General page or on an application-defined page in the Print property sheet. This member can specify the following flag.

PD_EXCL_COPIESANDCOLLATE

Excludes the Copies and Collate controls from the printer driver property pages in a Print property sheet. This flag should always be set when the application uses the default Copies and Collate controls provided by the lower portion of the General page of the Print property sheet.

nPageRanges

Type: DWORD

On input, set this member to the initial number of page ranges specified in the lpPageRanges array. When the PrintDlgEx function returns, nPageRanges indicates the number of user-specified page ranges stored in the lpPageRanges array. If the PD_NOPAGENUMS flag is specified, this value is not valid.

nMaxPageRanges

Type: DWORD

The size, in array elements, of the lpPageRanges buffer. This value indicates the maximum number of page ranges that can be stored in the array. If the PD_NOPAGENUMS flag is specified, this value is not valid. If the PD_NOPAGENUMS flag is not specified, this value must be greater than zero.

lpPageRanges

Type: LPPRINTPAGERANGE

Pointer to a buffer containing an array of PRINTPAGERANGE structures. On input, the array contains the initial page ranges to display in the Pages edit control. When the PrintDlgEx function returns, the array contains the page ranges specified by the user. If the PD_NOPAGENUMS flag is specified, this value is not valid. If the PD_NOPAGENUMS flag is not specified, lpPageRanges must be non-NULL.

nMinPage

Type: DWORD

The minimum value for the page ranges specified in the Pages edit control. If the PD_NOPAGENUMS flag is specified, this value is not valid.

nMaxPage

Type: DWORD

The maximum value for the page ranges specified in the Pages edit control. If the PD_NOPAGENUMS flag is specified, this value is not valid.

nCopies

Type: DWORD

Contains the initial number of copies for the Copies edit control if hDevMode is NULL; otherwise, the dmCopies member of the DEVMODE structure contains the initial value. When PrintDlgEx returns, nCopies contains the actual number of copies the application must print. This value depends on whether the application or the printer driver is responsible for printing multiple copies. If the PD_USEDEVMODECOPIESANDCOLLATE flag is set in the Flags member, nCopies is always 1 on return, and the printer driver is responsible for printing multiple copies. If the flag is not set, the application is responsible for printing the number of copies specified by nCopies. For more information, see the description of the PD_USEDEVMODECOPIESANDCOLLATE flag.

hInstance

Type: HINSTANCE

If the PD_ENABLEPRINTTEMPLATE flag is set in the Flags member, hInstance is a handle to the application or module instance that contains the dialog box template named by the lpPrintTemplateName member. If the PD_ENABLEPRINTTEMPLATEHANDLE flag is set in the Flags member, hInstance is a handle to a memory object containing a dialog box template. If neither of the template flags is set in the Flags member, hInstance should be NULL.

lpPrintTemplateName

Type: LPCTSTR

The name of the dialog box template resource in the module identified by the hInstance member. This template replaces the default dialog box template in the lower portion of the General page. The default template contains controls similar to those of the Print dialog box. This member is ignored unless the PD_ENABLEPRINTTEMPLATE flag is set in the Flags member.

lpCallback

Type: LPUNKNOWN

A pointer to an application-defined callback object.

The object should contain the IPrintDialogCallback class to receive messages for the child dialog box in the lower portion of the General page.

The callback object should also contain the IObjectWithSite class to receive a pointer to the IPrintDialogServices interface. The PrintDlgEx function calls IUnknown::QueryInterface on the callback object for both IID_IPrintDialogCallback and IID_IObjectWithSite to determine which interfaces are supported.

If you do not want to retrieve any of the callback information, set lpCallback to NULL.

nPropertyPages

Type: DWORD

The number of property page handles in the lphPropertyPages array.

lphPropertyPages

Type: HPROPSHEETPAGE*

Contains an array of property page handles to add to the Print property sheet. The additional property pages follow the General page. Use the CreatePropertySheetPage function to create these additional pages. When the PrintDlgEx function returns, all the HPROPSHEETPAGE handles in the lphPropertyPages array have been destroyed. If nPropertyPages is zero, lphPropertyPages should be NULL.

nStartPage

Type: DWORD

The property page that is initially displayed. To display the General page, specify START_PAGE_GENERAL. Otherwise, specify the zero-based index of a property page in the array specified in the lphPropertyPages member. For consistency, it is recommended that the property sheet always be started on the General page.

dwResultAction

Type: DWORD

On input, set this member to zero. If the PrintDlgEx function returns S_OK, dwResultAction contains the outcome of the dialog. If PrintDlgEx returns an error, this member should be ignored. The dwResultAction member can be one of the following values.

PD_RESULT_APPLY

The user clicked the Apply button and later clicked the Cancel button. This indicates that the user wants to apply the changes made in the property sheet, but does not want to print yet. The PRINTDLGEX structure contains the information specified by the user at the time the Apply button was clicked.

PD_RESULT_CANCEL

The user clicked the Cancel button. The information in the PRINTDLGEX structure is unchanged.

PD_RESULT_PRINT

The user clicked the Print button. The PRINTDLGEX structure contains the information specified by the user.

Remarks

If both hDevMode and hDevNames are NULL, PrintDlgEx initializes the property sheet using the current default printer. To initialize the property sheet for a different printer, use the wDeviceOffset member of the DEVNAMES structure to specify the name of the printer.

Note that the dmDeviceName member of the DEVMODE structure also specifies a printer name. However, dmDeviceName is limited to 32 characters, and the wDeviceOffset name is not. If the wDeviceOffset and dmDeviceName names are not the same, PrintDlgEx initializes the property sheet using the printer specified by wDeviceOffset.

If the PD_RETURNDEFAULT flag is set and both hDevMode and hDevNames are NULL, PrintDlgEx uses the hDevNames and hDevMode members to return information about the current default printer without displaying the dialog box.

During the execution of PrintDlgEx, the DEVMODE and DEVNAMES structures that you specified in the PRINTDLGEX structure may not always contain current data. For this reason, application-specific property pages as well as IPrintDialogCallback routines for the initial page should use the IPrintDialogServices interface to retrieve information about the state of the current printer.
