Datasheet::ImportASCIIFile

Description

Import ASCII file. This is an improvement(speed etc.) to ImportASCII.

Syntax

int ImportASCIIFile( LPCSTR lpcszFilename, AsciiImportOptions & stAscImp, DataRange * pRange = NULL, DWORD dwCtrl = 0 )

Parameters

lpcszFilename
[input] A full path ASCII file name
stAscImp
[input] An AsciiImportOptions struct that has been setup with import settings
pResult
[input] target DataRange. If NULL, it will import to current Datasheet.
dwCtrl
[input] additional options from the IMPASC_* enumeration.

Return

0 on success, otherwise returns error codes

Examples

EX1

void ImportASCIIFile_ex(string strFile)
{
        Worksheet wks = Project.ActiveLayer();
        DataRange dr;
        dr.Add(wks, 0, NULL, -1);
        
        AsciiImportOptions optASCII;
        init_ascii_import(optASCII.ascimp);
        init_CSV_import(optASCII, strFile);   
        
        DWORD dwCntrl = IMPASC_SKIP_QUOTED_EOL | AFCH_SET_NUMERIC_COL_BIG_ROWS;
        int nRet = wks.ImportASCIIFile(strFile, optASCII, &dr, dwCntrl);
        out_int("ret = ", nRet);
}

EX2

void ImportASCIIFile_Partial_ex(string strFile)
{
        Worksheet wks = Project.ActiveLayer();
        DataRange dr;
        dr.Add(wks, 0, NULL, -1);
        
        AsciiImportOptions optASCII;
        init_ascii_import(optASCII.ascimp);
        
        optASCII.header.MainheaderLines = -1;//to indicate scanning for main header
        string strMainheader;
        init_CSV_import(optASCII, strFile, &strMainheader);
        
        optASCII.partial.Partial = 1;
        lstrcpy(optASCII.partial.ColRanges, "2:0");  //---skip 1st col, 2:0 means from 2nd to last
        lstrcpy(optASCII.partial.RowRanges, "10:20");
        
        DWORD dwCntrl = IMPASC_SKIP_QUOTED_EOL | AFCH_SET_NUMERIC_COL_BIG_ROWS;
        int nRet = wks.ImportASCIIFile(strFile, optASCII, &dr, dwCntrl);
        out_int("ret = ", nRet);
