Using the UNICODE version of LEADTOOLS in a non-UNICODE Application

Show in webframe

Take the following steps to create and run a program that uses the UNICODE version of LEADTOOLS in a non-UNICODE application.

1.	Start Visual Studio 2008.
2.	From the main menu, select File->New->Project. In the New Project dialog, Select Visual C++\Win32 for the project type and select "Win32 Console Application" for the template. Enter a name (for example "chartest") and a location for your new project and then click OK. Click Finish on the next wizard dialog to create your new project.
3.	From the main menu, select Project->Properties. Under Configuration\General, set the "Character Set" to "Not Set". Click OK.
4.	Edit stdafx.h and replace the contents of the file with the following code (Note: you will have to change the path of l_bitmap.h to match the LEADTOOLS installation directory on your system):

// stdafx.h : include file for standard system include files,
// or project specific include files that are used frequently, but
// are changed infrequently
#pragma once

#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers
#include <stdio.h>
#include <stdlib.h>
#include <tchar.h>

#include "C:\LEADTOOLS 18\Include\l_bitmap.h"
// TODO: reference additional headers your program requires here

5.	Edit stdafx.cpp and replace the contents of the file with the following code (Note: you will have to change the path to the .lib files to match your system):

// stdafx.cpp : source file that includes just the standard includes
// chartest.pch will be the pre-compiled header
// stdafx.obj will contain the pre-compiled type information

#include "stdafx.h"
#pragma comment(lib, "C:\\LEADTOOLS 18\\Lib\\CDLL\\Win32\\Ltkrn_u.lib")
#pragma comment(lib, "C:\\LEADTOOLS 18\\Lib\\CDLL\\Win32\\Ltfil_u.lib")
// TODO: reference any additional headers you need in STDAFX.H
// and not in this file

6.	Edit the project's main .cpp (for example chartest.cpp) and replace the contents of the file with the following code (Note: you will have to change the path of l_bitmap.h to match the LEADTOOLS installation directory on your system):

#include "stdafx.h"

L_INT FileInfoExample(L_VOID)
{
   L_INT nRet;
   FILEINFO FileInfo;        /* LEAD File Information structure. */
   char szMessage[1024];  /* Buffer to hold information for display. */
   char szInputFile[_MAX_PATH]=MAKE_IMAGE_PATH("IMAGE3.CMP");

   /* Convert non-UNICODE to UNICODE */
   L_TCHAR wcsInputFile[_MAX_PATH]=L"\0";
   mbstowcs(wcsInputFile, szInputFile, _MAX_PATH);

   /* Get the file information */
   FileInfo.uStructSize = sizeof(FileInfo);
   nRet = L_FileInfo(wcsInputFile, &FileInfo, sizeof(FILEINFO), 0, NULL);
   if(nRet != SUCCESS)
      return nRet;

   /* Convert UNICODE to non-UNICODE */
   char szName[16];
   wcstombs(szName, FileInfo.Name, 16);
   char szCompression[20];
   wcstombs(szCompression, FileInfo.Compression, 20);

   /* Format the message string with data from the FILEINFO structure */
   wsprintf(szMessage, "Filename:   %s\n\n"
                       "Format:   %d\n\n"
                       "Width:   %d\n\n"
                       "Height:   %d\n\n"
                       "BitsPerPixel:   %d\n\n"
                       "Size On Disk:   %ld\n\n"
                       "Size In Memory:   %ld\n\n"
                       "Compression:   %s",
                       szName,
                       FileInfo.Format,
                       FileInfo.Width,
                       FileInfo.Height,
                       FileInfo.BitsPerPixel,
                       FileInfo.SizeDisk,
                       FileInfo.SizeMem,
                       szCompression );
   /* Display the message string */
   MessageBox( NULL, szMessage, "File Information", MB_OK );
   return SUCCESS;
}

int main(int argc, char* argv[])
{
   FileInfoExample();
   return 0;
}
