Introduction

Mapinfo tab to ESRI shapefile converter can convert MapInfo vector tables to the ESRI shape format. It is implemented as a command line interface to IMUT.exe.

Using the Code

This is a code sample, and will only work with Universal Translator Imut files.

char szExeFile[1024];
sprintf(szExeFile, "\"%s\\imut.exe\" CFGenerate " 
        "MAPINFO SHAPE \"%s/\" hggtemp1.dat LOG_STANDARDOUT YES", 
        (LPCTSTR)m_strImut,(LPCTSTR)strFilePath);

STARTUPINFO si;
GetStartupInfo( &si );
PROCESS_INFORMATION pi;
si.dwFlags = STARTF_FORCEONFEEDBACK;
si.wShowWindow = SW_HIDE;

if(CreateProcess(NULL,
    szExeFile,
    NULL,
    NULL,
    FALSE,
    CREATE_DEFAULT_ERROR_MODE,
    NULL,
    (LPCTSTR)m_strImut,
    &si,
    &pi))
{
    CloseHandle(pi.hThread);
    WaitForSingleObject(pi.hProcess, INFINITE);
    //GetExitCodeProcess(pi.hProcess, &dwExitCode);
    CloseHandle(pi.hProcess);
    
    FILE *fp;
    sprintf(szExeFile, "%s\\hggtemp2.dat",(LPCTSTR)m_strImut);
    if((fp = fopen(szExeFile, "wt")) != NULL)
    {
        fprintf( fp, "MACRO _EXTENSION TAB\n");
        fprintf( fp, "MACRO SourceDataset %s\n", (LPCTSTR)strFilePath);
        fprintf( fp, "MACRO DestDataset %s\n", strDstPath);
        fprintf( fp, "INCLUDE hggtemp1.dat\n");
        fclose(fp);
        
        sprintf(szExeFile, "\"%s\\imut.exe\" hggtemp2.dat", (LPCTSTR)m_strImut);
        if(CreateProcess(NULL,
            szExeFile,
            NULL,
            NULL,
            FALSE,
            CREATE_DEFAULT_ERROR_MODE,
            NULL,
            (LPCTSTR)m_strImut,
            &si,
            &pi))
        {
            CloseHandle(pi.hThread);
            WaitForSingleObject(pi.hProcess, INFINITE);
            //GetExitCodeProcess(pi.hProcess, &dwExitCode);
            CloseHandle(pi.hProcess);
        }
    }
}

Points of Interest

The tool can convert a lot of tab files (located in a different directory) to shapefile format. Manual operation is a tiring, trouble thing; it may cause an error.
