Take the following steps to create and run a program that uses the LEADTOOLS Network Virtual Printer Driver as an IPP printer:
1. |
Start Visual Studio 2008. |
2. |
From the main menu, choose File->New->Project... |
3. |
In the New Project dialog box, choose Visual C++ in the Project Types drop-down list box, and choose MFC Application in the Templates. |
4. |
Type the project name as “LEADTOOLS IPP Demo” in the Project Name field. |
5. |
In the Location field, use the Browse button to navigate to the Examples subdirectory (such as <LEADTOOLS_INSTALLDIR>\Examples\CDLL). Clear the Create Directory For Solution and Add to Source Control check boxes. Click OK. |
6. |
Click Next> in the MFC Application Wizard. |
7. |
Select dialog based application type. Then click Finish. Three folders will be created, entitled: "Header Files", "Resource Files", and "Source Files". |
8. |
From the Main menu, choose Project->Properties. |
9. |
In the Properties dialog box, choose Configuration Properties, then select C/C++, then select Preprocessor. |
10. |
On the right side set the Preprocessor Definitions Property to use LTVXX_CONFIG, then click OK. |
11. |
In Solution Explorer, open stdafx.h, and add the following code to the end of the file: |
#include "winspool.h"
#include "..\..\..\Include\Ltprinter.h"
12. |
In the Source Files, right -click the folder. Choose Add->New Item. Choose Code in Categories, and C++ File (.cpp) in Templates. Type Imports in the name field and click Add. |
13. |
Right-click Imports.cpp and click Open. Add the following code: |
#include "stdafx.h"
#if defined(WIN64)
#pragma comment(lib, "..\\..\\..\\Lib"L_VER_DESIGNATOR\\CDLLVC10\\x64\\Ltkrn_x.lib)

#endif // #if defined(WIN64)
14. |
Right-click LEADTOOLS IPP DemoDlg.h and click Open. Add the following function definitions to the CLEADTOOLSIPPDemoDlg class: |
afx_msg void OnBnClickedOk();
static L_INT (EXT_CALLBACK OnEmfRgsProc)( L_WCHAR*, HGLOBAL, L_UINT, L_VOID* );
static L_INT (EXT_CALLBACK OnJobInfoProc)( L_WCHAR*, DWORD, DWORD, L_VOID* );
L_L_INT EnableInternetPrinting();
L_VOID RegisterJobCallBack();
L_VOID RegisterEmfCallBack();
L_INT InstallPrinter();
BOOL SharePrinter(LPTSTR szPrinterName, LPTSTR szShareName, BOOL bShare);
15. |
Right-click LEADTOOLS IPP DemoDlg.cpp and click Open. Add the following function: |
//Locate BEGIN_MESSAGE_MAP(CLEADTOOLSIPPDemoDlg, CDialog) and add the following functions
ON_BN_CLICKED(IDOK, &CLEADTOOLSIPPDemoDlg::OnBnClickedOk)
//Add the following function implementations
