Creating A Database To Store All Of Our Equipment In?
Jun 19, 2012
I've been having some trouble wrapping my head around how to link the 4 tables I have together. I'm creating a database to store all of our equipment in. The four tables are Equipment, Service (Stores dates that a piece of equipment has been worked on), Invoice (Stores invoice and warranty dates) and Peripheral table (Stores a unique ID for each type of peripheral we have in the database. Monitor (1), mouse (2), keyboard (3) etc)

I'm a fairly new programmer so you'll have to bear with me on this. Basically, I have a database with 3 tables, Engineers, Equipment and Signouts. I want to create a VB application that allows engineers to sign out equipment. I have all of the forms setup the way I want, and have followed a tutorial online for how to connect to the database with the MySQL .NET Connector. I have 3 forms, and have a class with all of my global variables in it. All I have managed to thus far, is define connStr as a global variable, and use it to run a connection test when the main form starts up.
My next job is to query for information about an engineer based on their ID. I have a text input box, and a button to click, and then way to display the retreived information on the next page. I have setup variables for the returned values to be put against, so they can be displayed on the form.
My question is, when the button is clicked, how do I make the application query the database based on the ID, and then use the information it returns (Engineers ID, Name and Telephone Number) to assign those values to the variables? Also, on a side note, instead of using forms, I want to use panels, is there a sub routine similar to form_load for using panels when they are shown/hidden?

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

Basically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string
Do Until Integer.TryParse(Console.ReadLine(), LastName) = False
Console.WriteLine("Invalid input, Please try again")
Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.

For my website I've just implemented tinyMCE for my site (just a word processor). Everything works fine except when i try to store the string variable input into a sql server database. I want to store a string and not have the html tags make me exceed the 8000 length limit(the html tags take up most of that space). My question is, is there a solution so I can store my document with the html tags without shortening my document? Create an if statement that will determine the length If > 8000 than split the string apart and insert into separate fields. Maybe their is a compression feature which I'm unaware of?

I'm working on an application that is used by English and French users. French users have their computer's regional settings that make the decimal "," instead of "." and the number spacing " " instead of "," So, a French user will input a value "9,78" in a text box. I need to make this value "9.78" so I can safely store it in a database. How can I convert this to the US number format?

I try to store Korean langguage in Microsoft jet OLEDB 4.0 database, but I cant retrive it back.
CODE:
I try to google around for weeks..but still cant find the solution, I believe microsoft jet 4.0 should support unicode, but cant find any command like charset to set the character set.
I've try store with DataTypeEnum.adVarWChar/DataTypeEnum.adWChar/DataTypeEnum.adLongVarWChar.
I've set the regional and lagguage setting to korean(I can view korean in textpad).
I've try System.Threading.Thread.CurrentThread.CurrentCulture = New System.Globalization.CultureInfo("ko-KR") before retrive korean string also.
Now i have totaly no clue. just suspect, i need to do something when create the database or when read from the database, but dont know how.

I need to be able to accept a password from a user in a WPF app, encrypt it then store this in a database and be able to decrypt later on. However I'm not sure how to implement this.
This is completely trivial so whether it's safe or not doesn't matter. All I need is for it to get working only I'm unsure exactly how to do it. I've tried playing around with the DESCryptoServiceProvider() but haven't gotten anywhere.
To be clear, how exactly do I go about converting a simple password into something that's been encrypted and storing it in the database (and what fields would I store it in). At this point, I'm happy if there's only one key and that key is being defined in the source code.
