How To Make A Date Datatype Accept 13 As A Month And 30 For All Months
Jun 22, 2010I am in ethiopia and we have 13 monthes. 12 of them with 30 days each and 13th month with 5 or 6 days. I want to sort my data by date using the bindingsource sort method. But to do that I need to set my date field a date data type. When i set the datatype to date, i can't enter some values like 13 for the month value and 30 for day value of 2nd month.
What I want is just to make my application accept 13 as a month and 30 as a day for all monthes, so that i can sort my data by date. Is it possible to do so by setting culture for my application or by some other means?

Evernything is a string cause the data is coming from a textbox, I need to convert it to the datatypes used in the database.Also how do I use the CAST and Convert functions

Using SmallMoney DataType?
Nov 8, 2010I am converting the database in an application in Visual Basic 2008 from Access 2000 to SQL Server express 2009 R2 database. There are several fields that "SmallMoney" seems the mos appropriate to use. When I try to use the "SmallMoney" datatype in a Parameter, it won't accept it, the datatypes listed when I try to indicate the datatype does not inclue Mone or SmallMoney. It does include "Currency".
However the ere doesn't seem to be a "Currency" data type in Visual Basic. Would I be better of using Double and change the table definitions back to Double as they were in Access?

View 4 RepliesDataType - Double VS UInt32
Mar 30, 2010Just got an overflow issued and found that it was about the datatype. I fixed it and test it around
Change the datatype of Int32 to
1. UInt32 - 32bit
2. Double - 64bit
It works fine in my side. UInt32 Length should be long enough for me. I am thinking to use UInt32 as it "saves" more disk space (or probably runs a bit faster). However, what is the drawback if I always use Double ?
