[DeelynBaNi]

Hi all...i'm having a problem in formatting columns in excel. For example i have column Name, Birth Date and Salary and i want to format it to string, date and numeric respectively. When i format the columns using the codes below, all columns format become numeric. Any advise @ reference i can refer to?

objField = (ADODB.Field)objFields.Current;

 for (int n = 0; n < nFields; n++)
                                {
                                    switch (objField.Type.ToString())
                                    {
                                        case "adVarWChar":
                                        case "advarwchar":
                                            {
                                               break;
                                            }
                                        case "adDBTimeStamp":
                                        case "addbtimestamp":
                                            {
                                                ((Range)sheet1.Cells[1, n + 1]).EntireColumn.NumberFormat = "dd-mmm-yy";
                                                break;
                                            }
                                        case "adNumeric":
                                        case "adnumeric":
                                            {
                                                ((Range)sheet1.Cells[1, n + 1]).EntireColumn.NumberFormat = "0.00";
                                                break;
                                            }
                                    }
                                }

You are not looping through all the fields. You are running the loop for only the current field.

Yes looping is the problem :) Thanks
