Importing Excel file into Lotus Notes...how to import the Date values correctly?

Hi there,

working on a Notes database...one of its function is...that user will be able to import the Excel files.

Following is the code i am using to import the Excel files into Lotus Notes database...i found this on the web and alter it a bit for my needs.

so far...as far as my testing goes it is working fine. However i am not sure that how come i am getting the correct Date values. Please allow me to explain further.

Excel file that i am using for testing...in it couple of columns have Date values (i have set the format for all the cells in these columns as Date). And then using the code below...importing the Excel file in the Lotus Notes Db. And along with other values...getting the correct Date values from the Excel file. Even when i change the cell format of the Date  e.g. (13-Dec-07 or  September 19, 2008 or  11/26/08) i got the correct Date values in the Lotus Notes Db. i think what i am saying is that how the code below knows what is the month and what is the day from different cell formats that i have in the Excel file. The one thing that i found that even if i have different cell formats e.g. (13-Dec-07 or September 19, 2008 or 11/26/08) in the formula bar of the Excel it always shows as mm/dd/yyyy (is this is due to the control panel -> regional setting? and is this is why even with different cell formats i am getting the correct date values?)

what i like to make sure is this that when user will use the Lotus Notes Db and import their generated Excel files, how to ensure that the code below import the correct Date values
from the user Excel files. (like what if user does not format the column and its cells as Date, what if in the user Excel file the Date value stored as text or something). i do not know how?...may be some kind of check in the following code to make sure that the Date Values from Excel files will be imported correctly.

Following are the lines from the code below...where i am reading it from the Excel and storing it in the Date fields on the form.

cur_doc.Datefield1 = rs.Fields(8).value  
cur_doc.Datefield2 = rs.Fields(9).value

Sorry if it seems like a long story but i like to give as much related info as i can. Need your help.

    The short answer is "You don't need to worry about the date format being used".

    When you enter a date in an Excel spreadsheet, Excel uses your current date settings from the operating system to store the date.  The date is always stored in a date format.  When you format a cell, you are telling Excel to format the stored date in a particular way.  The data does not change, just the display of the data.  That is why you always get the correct date regardless of the format used to display it.

    Thanks for your reply Bill.

    And i like your short answer.

    One thing sure though, user need to make sure that the Date column in the imported Excel file is set to Date regardless of the format as you have confirmed. Because if it is set to text (and evne if user storing the date values in it) then i tested it that in the Lotus Notes even if i am storing the values in the Date type field in the property window field tab it shows data type of text.

    So please verify that as long as the Date column in the Excel file is set to Date, the imported dates values should be correct. Regardless of how i am displaying the date values in the Notes view as well.

    I think i am struggling to understand this, that lets say in the Excel file i enter date as mm/dd/yyyy and
    my current date settings from the operating system is also mm/dd/yyyy. so as you have already mentioned that that's how it will get stored...right. Now when using the lotus script when i import this value into Notes Db...how it get stored in the Notes Db, who tell that Date field on the form that what is the month, day and year is?

    Let say i have two different users with different Date settings from their operating system (Control Panel -> Regional and Language Options). one is United States(MM/DD/YYYY) and the other is Canada(DD/MM/YYYY).  

    One of the views in the system based on Date value will display the results for users differently.

    The requirement is to display the results in the Lotus Notes database based on a custom format (Oct 27, 2009) of the Date. so regardless of the user Date setting...All the users will view the results in the same format. I think this can be done by just changing the display properties.

    The other thing i need your help with is this...when i am reading the record set from the Excel file in the above code i like to format the Date value that i am getting from the Excel and then pass it to Lotus Notes database and the format that i like to have is United States(MM/DD/YYYY). So first get the Date value from the Excel file -> convert its format to (MM/DD/YYYY) then assign this value to one of the
    field on the Lotus Notes form and then reformat it to a custom format (Oct 27, 2009). Does any one now how?

    You can use like:
    cur_doc.Datefield1 = Format(cdat(rs.Fields(8).value), "mm/dd/yyyy")

    Pls check the Format function in Designer help for exact code. But you need to follow above way to get the exact formats.

    Hope it helps.

    For converting into this format Oct 27, 2009
    You need to do below:
    Dim tmpdate as Notesdatetime
    'cur_doc.Datefield1 = Format(cdat(rs.Fields(8).value), "mm/dd/yyyy")
    tmpdate= New Notesdatetime(Format(cdat(rs.Fields(8).value), "mm/dd/yyyy"))
    Dim tmpmnth as Number
    dim tmpdt as number
    dim tmpyr as number
    tmpmnth=Mnth(tmpdate)
    tmpmnthstr = Select(tmpmnth,"Jan","Feb",....,"Dec") ' Pls check the exact format in help.
    tmpyr=Yr(tmpdate)
    tmpdt = Date(tmpdate)
    dim finalfr as string
    finalfr = tmpmnthstr & " " & cstr(tmpdt) &", " & cstr(tmpyr)
    cur_doc.Datefield1 = finalfr 'I assume DateField1 will be Text field, else it won't take the assigned format.

    Apart from the above solution, there is one property you can use from notesdatetime class to convery to local regional settings.
    I hope it helps.

    Thanks for your reply madheeswar.

    Requirement is...in the above Lotus Script code, change the format of the Date value (cell) in the Excel (so to know exactly what we are getting from Excel - Change the format to (mm/dd/yyyy), its like before getting the value from the Excel, format the Date value in the Excel and then get and assign the value to Notes database.

    The above formatting is just after we are getting the value from the Excel file. (But in order to make sure what we are getting from Excel, need to format the value in the Excel  before getting it).

    So, this is more a question on Excel than Notes.
