I'm having trouble getting started with this application I need to do. Here are the details:
Its an application to calculate student grades for a group project. Create a text file to store names of 5 students, line by line. In a separate file enter peer evaluations from 0 to 1.0. Enter these numbers for evaluations:
1.0, 0.8, 0.9, 1.0, 0.6
0.2, 0.9, 0.5, 0.6, 0.7
0.5, 1.0, 1.0, 1.5, 0.9
0.9, 0.9, 0.9, 1.0, 1.0
1.0, 0.9, 1.0, 0.8, 0.9
This means that student 1 gave 1.0 evaluation for himself , 0.8 for student 2, 0.9 for student 3 etc.Student 2 gave 0.2 for student 1, 0.9 for him- herself, 0.5 for student 3 etc. Read these into a 2-dimensional array. If any of the values is greater than 1.0, set them to 1.0. The program should calculate the average evaluation for a student. While doing so, the program should ignore evaluations that student gave to him-herself. Populate a list box with student names when the form loads. The user should enter a project grade (same for everyone) in a textbox. Then the user can select a student from a list and click �Calculate� button. The program should display the project grade for that student by multiplying average evaluation by the grade for the whole group (project grade).

I am trying to learn by creating a small application to help my son learn math. It works but I know there are better ways of accomplishing what I need.
For example:
'Declare variables
Dim num1 As Double = CDbl(frmMath.txtNum1.Text)
Dim num2 As Double = CDbl(frmMath.txtNum2.Text)
Dim answer1 As Double = CDbl(frmMath.txtAnswer.Text)
[CODE]...
I imagine I would need something like a do while loop?

I'm writing a small application that downloads some files over ftp, the incoming directory is monitored by FileSystemWatcher_Created, on creation I want to extract some text from the file and call another application with the text as parameters the problem I have is the FileSystemWatcher_Created procedure is triggered before the file has finished downloading, I could download it elsewhere and move into the monitored directory but some of the files may be quite large and Im wondering if there is an efficient way of waiting until the file is ready? along the same lines what is the best way to queue the tasks as there can be many files coming it at one time, I've looked at threading but would that be suitable for such a task as there will still be a bottleneck at the application called by FileSystemWatcher_Created ?
heres an outline of what im doing:
Private Sub FileSystemWatcher1_Created(ByVal sender As Object, ByVal e As System.IO.FileSystemEventArgs) Handles FileSystemWatcher1.Created
'read text file

I am sending some data in a Serialized Structure across a TcpClient Stream to a Client. Now, sometimes the results get through, other times however, it does not. I've noticed this is true when the data I'm sending gets rather large. The server locks up at sending it and can't continue on.I'm sending this structure:
<Serializable()> Public Structure SearchResults
Public Property Results As String
Public Property Search As Boolean
End Structure
When Results gets kind of big (say, 411,000 characters in length), the server fails to send it, I get no error, and I end up timing out completely. If I connect via localhost", I get it instantly, so I know my code works. My problem is I've sent different structures with more data (2 million characters) way faster (nearly instantaneously) across the Internet (not localhost) in less than half a second.
Private Sub SendMessage(ByVal message As Object)
Try
SyncLock m_Client.GetStream
BinFormatter = New Binary.BinaryFormatter()

The instructions I found so far is to right-mouse click on the tool box, click 'choose items' and then select the Inkedit Control from the .NET Framework components.

I am developing a small application using VS2008, the mdiparent has a expandable panel with Button 1 and Button 2 on it, which opens up child form 1 and child form 2. ( The two child forms are maximized within the mdiparent form)
The problem is, button 1 opens child form 1 and button 2 - child form 2. I cant open the two forms randomly. I have to close the topmost form to access the other forms below it and vice versa.

I am trying to make my program print out a requistion slip but I don't want to make a report using VB b/c sometimes the printer is not connected and it is better to have a Microsoft Word document and save it as such. So how do I create a Word application from VB? I basically am going to set out a format, make a small table etc. and then whatever the user types in the textbox, it will appear in the slip. (I am using Word 2003)

I am having a problem in Form_Load. When the following code executes the form pops up with out executing any further code: Me.TblAssetsTableAdapter.Fill(Me.ITP400_IP3_ADataSet.tblAssets).
I am trying to use Form_Load to populate values in a ListBox control from an Access database table.It appears the problem was in the Compile settings. It was the 'old' problem of using AnyCPU on an x64 machine. I changed the Compile setting to x86 and the problem disappeared.

So in my window onLoad method I am pre-populating a grid with values retrieved from a database. Here is the method below for the window load:
Private Sub winMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
''#Load Grid
Dim dt As New DataTable
With dt
[code].....
What happens is, when I press F5 to debug, the program loads, and the grid is still empty, just as it is without a datasource. When I try to step through the code, it actually reaches down to the line that reads
Budgets = BudgetManager.Process.Budget.GetAllBudgets()
and then stepping over this line...the window loads and it doesn't go any further in the method. What the line of code above does is eventually make a execution call of some SQL to a SQLite database, and the code gets to the point at which it calls the execute method, but doesn't even make the query yet. All the objects up until that point in the code are set properly as well (found through debugging and checking locals.)Edit:Exception is this:
"Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

I have a vb.net 2008 application which has its corresponding icon.
The icon shows correctly except in the taskbar when the "small icon" setting is on.
My vb.net project includes a .ico file which when I see in the IDE includes 16x16, 32x32, 48x48, 64x64 and 256x256 bitmaps, in 4, 24 and 32 bits, also 3 .png images in 256x256 32 bits each.
I made the icon myself simply using a 64x64 bitmap and then converting it to .ico, and assigning it to the application in the project properties. I thought windows would use and escalate the corresponding image, it shows even in the file explorer properly in the small icon form, but not in the taskbar.
