If you are using Origin 7.0 or later the following OriginC function will do the job ...
bool wks_col_remove_char(string strWksName, int ColumnNumber, char Character)
{
Worksheet Wks;
if (Wks.Attach(strWksName))
{
Column WksCol;
if(WksCol.Attach(Wks,ColumnNumber))
{
int NumRows=Wks.GetNumRows();
string strCellValue;
for(int i=0;i<NumRows;i++)
{
Wks.GetCell(i,ColumnNumber,strCellValue);
strCellValue.Remove(Character);
Wks.SetCell(i,ColumnNumber,strCellValue);
}
return (true);
}
}
return (false);
}
