I am in a visual basics 2008 class for my MIS degree. This is the beginners class. We were instructed to build a program that calculates a score average. However, we get extra credit if we figure out how to drop the lowest test score. I do not know how to do this. The teacher won't help with the extra credit. I will post my code.

I am trying to intercept connections on port 2302 that is being used by a game. I was think about using something along the lines of
#Region " Imports "
Imports System
Imports System.IO
Imports System.Windows.Forms
[code]....
I'm running this on Microsoft Visual Basic 2008 I want to make a program with 2 forms, one with buttons, the other that will just hold picture boxes, which are created when those buttons are clicked. Once those picture boxes are placed on the second form, I want to be able to drag and drop them to move them anywhere on that second form.
I have it "working" as of right now, but it's really glitchy. Almost as if it can't keep up with my mouse movement. But I'm not moving THAT fast so I can only assume that something is wrong.The buttons work so I won't post that code here but the following code is for the second form and what I'm using to control the picture boxes.
Public Class Form2
Private counter As Integer
Private boxCounter As Integer
Private list As New ArrayList
[code]....
Right now I have checkboxes on my form, and depending on what check box I check, the value of it gets put into a text box. So if I check "Right Eye", the texb ox below it gets "Right Eye" placed there.
I would like to do away with the check boxes and instead have a new form pop up with a list of words that gets populated from a table. Is it possible to be able to drag and drop these words into a text box? I guess I could use a List Box control for that but I'm unsure how to implement drag and drop. Maybe be able to multi-select words and then drag them all to a certain text box.
I'd like to have give the user the option of adding and deleting words from that form as they see fit, so could I just let VS do that for me by dragging the datasource onto the form and have it create a bindingnavigator or should I do it myself?
Trying to parse this and return the following 3 items: [code] Using this regex expression below I get the matches, but drop the leading "-" at the front of each grouping. I get the "-" in the middle of the group though. [code]

View 1 RepliesAn order can have many OrderDetails, and a Product can be on many different orders. The OrderDetail table just has the OrderID and productID, so there is essentially a many-to-many between order and product).I have a form for the user to enter a new order. I want to have an unbound box that contains the names of all the products, and to be able to drag these names into a box under the order, to add a new OrderDetail record using the productID of the dragged order along with our orderID.
View 1 RepliesI am having trouble with a socket client application written in vb.net using Visual Studio 2005. The client connects to a C language socket server that is running on OpenVMS. The problem that I have is that when the server sends a packet, the client does not receive the last byte (of every packet!). I can dump the packets on the network and the data is all there. My current solution is to keep my socket messages short (247 bytes) and send one extra byte past the end of my data.
I would like to include more information in my messages and I cannot find a way to make this work. If I knew 100% how long the packets will be on the network, I could work around this by including an extra byte in just the right places. However, I don't want to make any assumptions about the length of the packets.
Here is a sample of my client receive code:
Private Sub ReceiveMsg()
Dim nTotalBytes As Integer
Dim nNumBytes As Integer

I am dragging and dropping data from a combobox to a datagrid. I'm using VS2010 VB for a windows app. My problem is that the DragDrop event for the datagrid gives x,y mouse positions that are relative to the physical screen that I am using, not the datagrid. So when I use hittest to calculate the row and column the result is out of the bounds of the datagrid. If I manually drag the form around the physical panel, the x,,y coordinates on the dragdrop event chage accordingly. This is really strange.
View 2 RepliesScenario:I am attempting to perform some work on files (rename/delete) in folder, usually in a network location. Because the location of products folder is not critical, it's rarely ever in the same place on different networks. A simple shortcut on the client machine is all that's required from the client perspective and the rest of the product is self contained on the server somewhere. To run the 'fix' my small application will perform quickly and easily, I need to parse the path held in the target box of the .lnk. Then perform ifexists for a specific file and then do my renaming/deleting.
To keep it as simple as possible, the end user should just 'drop' the shortcut onto my form then click 'fix'.The problem: How in the heavens can I retrieve the target location from the .lnk into a string without windows scripting host?
Make a folder, based on an input file - example :
You have a file named Movie1.avi on your desktop, u open up the program (that I want to make) and then simply drag drop that file into a box area, and then the program will create a folder, with the same name as the input file, but without the extension (folder name Movie1) and then automatically put that file into the folder it just created.
The new folder will be created in the same dir as the input file.
Multiple file support - is NOT needed.
I know how it will be done, but I don't know the code..
I want to drag-drop single text items from ListView-A to ListView-B (both are in Details mode), but can't see how to read (and hence highlight) the index of the line in ListView-B when the mouse is hovering over it. Easy in a ListBox, but the PointToClient > IndexFromPoint features don't work with ListView controls and I just can't see another way .

Get lowest number from different TextBoxes?[code]...
Now im looking to get the lowest number in one of the ".checked" TextBoxes and add that number to a new Array.
I'm trying to save an image with the lowest possible quality. The lowest I got with a few colors was using the SaveJPGWithCompressionSetting the file size was 43kb.What im trying to achieve is something like remote desktop, the client constantly takes images for the current desktop then send its via TCP to the server(because I cant figure out any other way to get desktop stream). Everything works great but If I want to be more Real-time the image quality needs to be lowered. I can create 43-50kb desktop snapshot of a 1600x900 resolution,

I have a homework assignment to code an application that allows the Prof to display a grade based on the numnber of points he enter. The grading scale is : 0-299 -F; 300-349- D; 350-399- C; 400-449- B; 450-500- A. We are to store the minimum points in a 5 element one dimensional Integer array name intPonts and store the grades in a 5 element one dimensional String array name strGrades. The arrays should be parallel arrays. The procedure should search the intPoints array for the number of points entered by the user and then display the corresponding grade from the strGrades array.
I have stored the minimum points and grades in a one dimensional integer and string array respectively. I have coded the program, and when I put in random points, it gives me the letter grade. For example, if I put in 376 it will display a "C"; if I put in 200, it will display an "F". However, if I put in anything over 449, it will NOT display an "A", it just leaves the lbl blank. I am stumped on how to get the code to read pass 449 points.

Write a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
