Description

Get one dataset's range.

Syntax

bool GetRange( int & c1, int & c2, int nIndex = 0 )

bool GetRange( Datasheet & ds, int nIndex = 0 )

Parameters

c1: [output]begining column index (0 based)
c2: [output]ending column index (0 based)
nIndex: [input]the index of the data. DataRange can reference multiple sets of data. Index starts from 0.

ds: [output]the datasheet that contained the datarange
nIndex: [input]the index of the data. DataRange can reference multiple sets of data. Index starts from 0.

Return

true for success or false for failure

Examples

//Print out the begining and ending index and datasheet of the DataRangeEx.
void DataRangeEx_GetRange_Ex1()
{
    //assume the active workbooka sheet and has least four columns before run this code.
    Worksheet wks = Project.ActiveLayer();
    if ( !wks )
    {
        printf("Can not find any active worksheet!");
        return;
    }

    DataRange dr;
    dr.Create();//init the object
    dr.Add("X", wks, 0, 0, -1, 0);
    dr.Add("Y", wks, 0, 1, -1, 1);
    dr.Add("X", wks, 0, 2, -1, 2);

    printf("DataRangeEx's range is from %d to %d in datasheet %s\n", c1, c2, dsh.GetName());
