dateUntil=cstr(convNull (objHistoryRate("dtRateTo")))
strGrid =strGrid+ " <TD><INPUT type=""text"" size=15 id=txtdateUntil name=txtdateUntil value='"+ dateUntil+ "'></TD>"
function convNull(str)
if isNull(str) then
convNull = ""
else
convNull = str
end if
end function
Please help me to explain why we are using cstr the first code. I have not understood the string.

what is the value that comes with objHistoryRate("dtRateTo")? Also I hope that you should use AMPERSAND (&) instead of PLUS (+) there for concatenation.

the value coming from "dateRate" are date like 09/09/2004 and
for "dateHourlyRate" is 50. I hope this will help you to give the explanation. Thanks

Hi Shoakat,
I could see the usage of CSTR required when the "dtRateTo" contains any of the following possible values.
If it contains Date - then the CStr function will return a string that contains a date in the short-date format.
If it contains Null - then a run-time error will occur.
If it contains Empty - then the CStr function will return an empty string ("").
That is the reason too for using a ConvNull function there.
Hope that explains.
Cheers!
