Im wondering if how to convert 02/14/2012 to this format '20120214'
I want do save date in my database in that format...because I see it more flexible
I have a strange issue here. I am working with an access DB that has a field called CompleteDate. Here is my problem; There is a leading 1 in the dates. For instance, today's date format should be 110308 however, in the database the format is 1110308. How can I strip off that leading 1? Can I do this in access or, must I deal with this in my VB program?

View 8 RepliesI'm supposed to write a program that validates an inputted ten digit ISBN number using the check-digit at the end to ensure that the sum is a multiple of eleven. Before calculating this and detecting if the entered number is indeed a valid ISBN, we're required to check the first nine digits and see if they are indeed integers. After this the tenth digit is checked to see if it is "X" (for ten) or 0-9.
With the code I've written it keeps returning false for whether or not the ISBN is valid, even with valid numbers. I feel like its something to do with the hyphens; have I misused the replace function?I'm a little lost on how to make my code work, but I'm fairly certain my logic is okay so far.

I have a simple form (textbox) bound to a dataview which includes a date. I bind the date column using TextBox5.DataBindings.Add("Text", dvCampaigns, "CamBdate")Doing so shows the results as '1/1/2011 12:00:00AM'. I want the time to not show with this date. I can reformat the date using the TextChanged method of the text box and I can live with that if I cannot find a more efficient way. Is there a way to format the date upon binding in the above line of code? Also where can I find a listing of all the allowable properties for binding statement above? Intellisense implies that there are more then just the "Text" property but I cannot find them in BOL or MSDN. My thought is that there might be a property to do this in one step rather than reformatting it.

I'm new to programming and am trying to learn how to developed data driven application and was wondering which method is recommended? I know there are some debates out there but most of the books I have recommend using object binding, but it doesn't offer any concrete information on how to implement it. I went to MSDN and most, if not all, the documentations are on dataset. So I guess my questions is, object vs dataset, which do you use?

View 3 RepliesI'm fairly new to ASP.NET & VB.I've been asked to take an existing textbox that is automatically filled with the current date and allow the user to either add a "+" or "-" and a number or a spcific number and convert that into a date.I underdstand the basic concept on how to do this, but I'm running into some problems using the proper commands in order for this to work.The Textbox is called txtDate.What I've tried to do is this:
If txtDate = '+' Or '-' Then
DateAdd("d", txtDate, today)
End If

I am trying to parse a date from a textbox and store it in a date variable
Dim enddt_2 As Date = Date.ParseExact(txtenddt.Text, "dd/MM/yyyy", System.Globalization.DateTimeFormatInfo.InvariantInfo) 'txtenddt.Text
expenddt_1 = enddt_2.AddDays(-1)
enddt = enddt_2.ToString("dd/MM/yyyy")
enddt is a Date variable and when i convert enddt_2 to a string i get the error as
Conversion from string "17/01/2012" to type 'Date' is not valid.
Let me clarify, if a value in textbox is 17/01/2012 than after parsing the value is changed to 01/17/2012 (my systems Region and Language are dd/MM/yyyy) in enddt_2 and when i try to convert to dd/MM/yyyy format and store into a date variable i get the above error. This error comes only for the dates after 12. i.e a date variable accepts a date in MM/dd/yyyy format.The dates before 12 work fine, i.e for all dates from 1 to 12 there is no error.How can i make enddt store the date in dd/MM/yyyy format.
For example, today is 05/11/2009, I have two text box.
Actually it means that whatever what date i choose within the current month, the two textbox will display the last three months date.
For Example, Current Month is November 2009 , Textbox 1 will show 01/08/2009, Textbox 2 will show 31/10/2009.
Another example is Current Month is January 2009, Textbox 1 will show 01/10/2009, Textbox 2 will show 31/12/2008.

I am trying to create a basic webpage that will check a column of a database table to see if a "UPC Code" is taken already, to prevent duplicate use. I'm fairly new at .NET programming, but have built asp pages before. I'm just stumped :/
I have a textbox that a user can type in a number. The page successfully checks to see if the textbox is blank and reports the error, and if there is a value, it's supposed to bind that textbox number to a gridview to see which Item# it's associated with. But for some reason, my code is not binding the value of the textbox to the gridview.
Code:
<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
CodeBehind="Default.aspx.vb" Inherits="UPC_Checker._Default" %>
<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
