This function displays the Print dialog and creates a device context.
Parameters
Name | Explanation |
---|---|
hWnd | The window handle |
hDevMode | The handle of the DEVMODE structure (The handle retrieved by IKGetDevModeHandle) |
IkPrnDlg | The Print dialog settings |
Return Value
Returns the device context if successful. Returns null (0) if unsuccessful.
Explanation
The IKPrintDlg function displays the Print dialog and creates a device context using the information specified. By setting hDevMode, the "Print" dialog can be displayed with the printer name and printing information. To use the current printer with its existing settings then set NULL or 0 in hDevMode. The IKPrintDlg member variable values are displayed in the "Print" dialog when it is initialized and changes made to those settings in the "Print" dialog box are returned to the member variables when the printing is complete. For more information, please refer to IKPRINT_DIALOG in the Structure Definitions and Explanations in the IK8Print.dll, IK8PrintA.dll, IK8Print64.dll, IK8Print64A.dll section. The device context is freed using the IKPrintDeleteDC function.
If the IKPrintDlg function is successful, the device context is returned which is used by the IKPrintStartDoc function.
Printing example code:
(1)C++Builder/Visual C++HDC hDC;
IKPRINT_DIALOG IkPrnDlg;
memset(&IkPrnDlg, 0x00, sizeof(IkPrnDlg));
IkPrnDlg.Copies = 1;
IkPrnDlg.Options = 0x4 | 0x8 | 0x100000
//In Visual C++, pass Form1->Handle to m_hWnd
hDC = IKPrintDlg(Form1->Handle, NULL, &IkPrnDlg);
if (hDC == NULL) return;
if (IKPrintStartDoc(hDC, Form1->Handle, "", "", "", "ImageKit Print Sample") != FALSE) {
IKPrintStartPage(hDC);
// Display image, draw text or shapes, etc.
IKPrintEndPage(hDC);
IKPrintEndDoc(hDC);
}
IKPrintDeleteDC(hDC);
(2)Delphi
DC: HDC;
IkPrnDlg: IKPRINT_DIALOG;
FillChar(IkPrnDlg, SizeOf(IkPrnDlg), 0);
IkPrnDlg.Copies := 1;
IkPrnDlg.Options := $4 or $8 or $100000
DC := IKPrintDlg(Form1.Handle, 0, IkPrnDlg);
if DC = 0 then Exit;
if (IKPrintStartDoc(DC, Form1.Handle, '', '', '', 'ImageKit Print Sample') <> False) then
begin
IKPrintStartPage(DC);
// Display image, draw text or shapes, etc.
IKPrintEndPage(DC);
IKPrintEndDoc(DC);
end;
IKPrintDeleteDC(DC);
(3)Visual Basic
Dim hDC As Long
Dim IkPrnDlg As IKPRINT_DIALOG
IkPrnDlg.Copies = 1
IkPrnDlg.Options = &H4 Or &H8 Or &H100000
hDC = IKPrintDlg(Form1.hWnd, 0, IkPrnDlg)
If hDC = 0 Then Exit Sub
If (IKPrintStartDoc(hDC, Form1.hWnd, "", "", "", "ImageKit Print Sample") <> False) Then
IKPrintStartPage(hDC)
'Display image, draw text or shapes, etc.
IKPrintEndPage(hDC)
IKPrintEndDoc(hDC)
End If
IKPrintDeleteDC(hDC)
