I have a question regarding unusual date format. I have validation set to where users must input 8 digits for the date that I intend on formating dd/mm/yyyy. Is there a date function in .NET that I can use or am I going to have to manually set up my own function to output those numbers in that format?

I'm new to the world of VB.Net <-> Databases.I'm currently working on an application with SQL Compact 3.5.I realize that data et values on objects from the database but what I want is more custom...Students should have 3 fields for example, tableId, their name and birthYear.1 | John | 20002 | Peter | 1999And so on. What I want is to display their birthday on some label.text = "(" & DBvalue & ")" based on the selection of a listbox (which has tableId's listed as values). You don't have to worry about the update method of that label.text value, I just want a way to retrieve the birthYear value and put it into my label.text together with those extra characters, based on the tableId selected. (which I already have a way to get, so don't worry about that either).

How do I change the number of gridlines a chart displays? My chart data runs from 00:00 to 23:59 but due to the auto scaling I get gridlines and labels at funny time e.g 05:37 or 10:23. What I'd like is a label and line every hour but I can't find which property sets it!

I am not stuck with the code side but rather what seems an issue when using VB and creating well verifying an Twitter Account. I have tried to explain as best as possible but please ask if you need more info
I am currently well on the way to finishing my Twitter Account Creator which also verifies and completes the profile fields but I have encountered a problem and for once not a problem relating to the code side of things at least I don't think it is.
At the moment for testing reasons I have 2 buttons one which creates the account and a second which verifies the account now I am using incognitomail.com (temp email provider) and have 2 web browsers running within my VB program. 1 is for Twitter and 1 is for Incognitomail.com I have no problems clicking and navigating to the verify link and then logging in to verify the Twitter Account but it never verifies and I cannot figure out why.
Say I put another text box and used it to navigate to url's on web browser 1 (twitter) and copied the verify link and put it in the text box it navigates I login and its the fine the account is verified but if I set VB to navigate (can't click because it opens in IE and not within the VB web browser) to the verify link it never verifies I have even tried making the text box fill and then navigate via that just as if a human was doing it but still no luck.
Does anyone have any idea as to why these Twitter Accounts are not verifying when the VB program performs the navigating to the verify link then login but if I do it myself i.e copy the verify link put it in the text box which navigates the web browser then it verifies fine?This is the one step standing in the way from my program being about to create and verify accounts and will not cost a fortune as this was a personal project to counter the lack of Twitter Creators which both work fully and are cheap.

i'm importing a text file into a access table like this:
vb.net
sql.CommandText = "SELECT * INTO [tblMailList] FROM [Text;DATABASE=" & frmMain.FolderName & ";HDR=NO].[" & frmMain.TextBoxFileName.Text & "]"
sql.ExecuteNonQuery()
my question is what is the best way to add an autonumber to the table? i currently do it like this:
vb.net
sql.CommandText = "ALTER TABLE [tblMailList] ADD COLUMN [ID] AUTOINCREMENT;"
sql.ExecuteNonQuery()
but when the file is too large i get this error: "File sharing lock count exceeded. Increase MaxLocksPerFile registry entry."
and yes, i have tried to change the registry entry and it didn't work:
vb.net
My.Computer.Registry.SetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesJet 4.0", "MaxLocksPerFile", "9000000")

I have a small page, with a button on it. When I click the button I'd like the code to look at a a field (call the field "InvoiceNumber") in a table (call it "InvoiceTable"), take the last number stored, increment it by "1" then store it back in the "InvoiceTable" and display the new invoice number on the page.Currently the button is called "New Invoice", so clicking this button is going to create a new invoice, with a number one newer than the latest one in the table.

I have a teradata backend that uses auto increment. The form is databound i.e dragged a column to the form which gave me the navigation header etc.The problem I'm having is when user 1 opens a record the auto increment goes +1, let's say we're at 45 now, then user 2 opens a new record and it also goes to 45 as user 1 has not saved. Why is the databinding not locking 45 when the first user opens it

I'm using VB.net to write a MYSQL application and one feature I need to add is the ability to add a column for each week that my employees worked. For example I want the first column to be called "W1" and the next one to be "W2" and so on, right up to "W52". How would I add a column to my table and have it's name add 1 to its current value? If there wasn't any letters in the name it would be easy but I need it to have the "W" in the title as well to avoid confusion. to add the column I have this:
Alter Table Manager ADD W1 MediumINT;
I just need the part that adds an INTEGER to a VARCHAR datatype if possible... Maybe there should be some sort of data type conversion involved? Just to explain further, the black bar at the very top are the date stamps for each week, I would like to have this included in the datagridview if possible but it is not required. Under each week column the employees will be entering the percents they worked (example: 20%, or 0.20 is one day of work) I know this is an odd way of doing things but its mandatory... and i was wondering if it were possible to automate the creation of these columns rather than me having to manually enter them.

From within Excel, I want to import data from Access. This is simple enough using Microsoft Query. What is not so simple, at least to me, is how to get the SUM of numbers in a specific field in a specific table in Access. I do not need to import every number in the field only the SUM of the field. I need this 'total figure' to be placed in a cell in an Excel spreadsheet.
The data is listed in the Access table in this order: (there are others but these are the three I am interested in)
TimeStamp, Terminal, TransActionTotal
Simplistically, there are three cells (A2, B2, C2) on on the spreadsheet (one for each terminal). The first should show a total for the day for Terminal 1, the second for Terminal 2 and the third for Terminal 3. Is there a way to get Excel to read the data in the table, add up the appropriate fields by date and then write this total in the appropriate cell? If it makes it any easier, the date is recorded in another cell on the spreadsheet (let's say E1).

I have a string which contains html code from a webpage. There's a table in the code I'm interested in. I want to parse the numbers present in the table cells and put them in textboxes, each number in its own textbox. Here's the table:
<table class="tblSkills">
<tr>
<th class="th_first">Strength</th><td class="align_center">15</td>
<th>Passing</th><td class="align_center">17</td>
[code]....
As you can see there are 14 numbers. To make things worse numbers like 19 and 20 are replaced by images and numbers lower than 6 have a span class.

I do this in Oracle databases just in a snap, but now I have to do it in VB using ADODB and I don't know how to do it.
I have two Access 2007 tables. Table A contains: Col1 (text), Col2 (text), Col3(date), Col4(amount), Col5(text)
Table B contains Col1(date), Col2(amount) What I need to do is to insert into table B the records of table A (col4 summed) grouped by date of table A. The date is a variable contained in a text box so it cannot be hardcoded into the SQL statement.

I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.
[Code]...
I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.

I have a program that will load a web page into the Program Contained 'Webbrowser1' and autocomplete the Login by referencing the Code:
WebBrowser1.Document.GetElementById( _
"frmLogin:strCustomerLogin_userID").SetAttribute("Value",
TextBox1.Text)
What I actually want to do is directly enter the Value into the Active Browser page, rather than the program contained 'Webbrowser1'. What code do I need to access the Current Browser Web page (be it IE, FireFox etc)?

I've an old vb6 ocx in order to show an msgbox with autoreply in n seconds.
rm = waitMsg("can't connect to host...",9,"*Retry","Cancel")
if rm = 2 then exit sub 'cancel
acts in same way of msgbox, but after 9 seconds (in the example) then auto click the Retry button (the default button, the one with * prefix). maybe I could convert this old ocx to net, but wondering if there is not an better alternative using messagebox.
