Jan 28, 2012
The company require an application that displays coffee usage information for the managers of CostaB Coffee. Sample data has been provided for last years (2011) monthly usage amounts in kilos and is as follows: 400.5, 450, 475.5, 336.5, 457, 325, 220.5, 276, 300, 320.5, 400.5 and 415.
Requirements: The main form will allow the user to enter and store monthly amounts in an appropriate data structure. It will enable the users to calculate the total usage for the 12 month period and average monthly usage. A further requirement for the application is for the users to be able to display the monthly totals in ascending (smallest to highest) and descending (highest to lowest) order of the monthly usage amounts. Utilise appropriate formatting for input/output and include appropriate error trapping and data validation in the application.

I need to quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?

I am trying to implement login page using Form Authentication in ASP.net using vb code.I follow the steps in How To Implement Forms-Based Authentication in Your ASP.NET Application by Using Visual Basic .NET. I created a function in login page :
Private Function ValidateUser(ByVal strUsername As String, ByVal strPassword As String) As Boolean
and call it in btnLogIn_Click
Protected Sub btnLogIn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogIn.Click[code].....
Things works fine and i can get the username display in label.However,I need to get more user data like UserName, Fullname and RoleCode. Also, i would to display the user's fullname to instead of usename in welcome message. I was told this can be done using FormsAuthenticationTicket method to store addictional user data in the "my user data" section. Do i need to create a user data class to store the user data and then use it in the FormAuthenticationTicket? If yes, how should i do it?

What I want to do is display large amounts of text and a few pictures, ideally with hyperlinks between the pages. A lot like wikipedia really, lots of similarly arranged pages, text in categories with in-line hyperlinks and the occasional picture to illustrate a point.But not online, integrated as part of a larger app.
How would it be best to go about doing that? The display method is sortof dictated by the storage method. My thoughts were:
Lots and lots of labels stored in an Access database
Straight HTML as if it were a webpage embedded in an iFrame or something
Labels populated from XML files?
Program the whole lot in Flash or something else (A language I can't speak)
This is only a mockup for demonstration purposes so the priority is user-friendlyness and ease of programming rather than storage concerns or good programming form.

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

the project here is to take the three amounts from three text boxes entered by the user and return a string in a label telling the user if the triangle is either a right triangle, equilateral triangle, or neither after clicking a button. The code I have must use a new Class named Triangle. No matter what is entered in the text boxes, the label always returns "You created a right triangle!"

Since some of my users log on as non-administrators, (without administrator priveleges), where would you reccomend I store their programs data files. For example, the program Test Prog would store user data in: [code]The problems is permissions file access when they are not signed on as the administrator and they need read write access to their data files. Also is there a universal system directory name I could use so it would be the same on all users computers, like %Documents% or something?

I would like to develop a program to create a report after reviewing a facility's processes (Quality Issues). The reports are to be created using Microsoft Word 2010.
I'm OK with developing the forms and controls to access the form and the user inputs.
What I need guidance on is the best way to save the input information from the user forms (over 100 total) as it relates to that facility, and to retrieve the info in case clarification is needed. Also, each user may have several facilities to review.

How do i load the Main form of a WPF so that a seperate thread goes and gets data from the database while the form is in an apartmentstate? (drag-able / movable) I Know this is possible with opening a new window from your main form like this :
Private Sub openOrderWindow()
Dim OrderWindow As Orders = New Orders
OrderWindow.ShowDialog()
End Sub
[code]....
I've tried putting MyBase.ShowDialog() and .Show() and .9000+ other things The only benefit I've got out of using a seperate thread to load from the databse is i can see the screen right away (as oppose to it being a transparent box until it loads) but i cannot move it around or minimize it?is there any way to make it Movable while it loads?
