Adding An Integer With Each Click?
May 7, 2009
The problem is trying to update and add a number to a summary label each time a math problem is answered correctly or incorrectly. As it is now, it will only add + 1 to correctNum and incorrectNum regardless of how many times I press the button.
This is the entire code, but I bolded the button I mentioned.
Public Class MainForm
Dim answer As Integer
Public Sub MainForm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

I am trying to understand the do until loop when adding numbers along with a variable to a new line in a textbox, incrementing each time. My current example is very simple but only returns the first value. I require the output to be incremented automatically, so I thought a do until loop would be best.

I have a small project that may be a big one - I'm really not sure. I want to add some right-click options in windows to certain file types. I don't want to change the default program for these file type - I just want to add some right-click options.
For example - I have a program that will convert .3GP movies to Quicktime movies. I do not want to change the default player for .3gp movies - I want user to be able to right-click on the movie and offer them an option to convert it to Quicktime.

I've written a little application that uploads selected files to my ftp server. What I want to do now, is add that application to the windows right click context. For example, I've installed anti virus, if i right click on my desktop there is a there is a new item within the right click list which lets my right click on files and scans. What I want to know is, how to I add my application into the right click menu, how to get my application to respond when I click on the entry in the right click menu and any other thing anyone thinks will be useful. I have never done this before, and I have never been taught in class.

Im looking to add some information to a table in VB.net.The table needs 2 columns and a number of rows;1 Column needs to have numbers ranging from 1 onwards, basically representing their row number. And 1 more column which just displays any text when a button is pressed.
Each time the button is presed i need the text to go onto a new row.Ive heard alot about a DataGrid, but everything relating to this seems to be based with SQL and I was wondering if there is a differnet tool which would be simpler to use?

In the example from my book, I'm coding a button click event, and adding the code..."me.width=me.width + 20"The author states that "me refers to the object to which the code belongs(in this case the form)".
But this isn't exactly accurate, is it? The "code belongs" to the button object -- not the form object, right? So, I'm guessing that what the author really should have said is that "me refers to what ever form you're working on". Would that be true?

VB 2003 Combobox collection from -3 to +3 The goal of the message is to warn the user that the systems only covers +- 3 timezones, if he types in for example +4 or -4, he gets the message (by the way: how to protect the system if he types for instance a character?)
When I run the application: 'Unhandled exception: Cast from string "click" to type 'integer' is not valid

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?

item = item.NextItem

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.
After the conversion, the code look like this:
Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer
[Code]...
Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

I have a LINQ2Entity problem, I want to get the value, string, from a database, so I select FProducts.Serial_number, and to end the query, I do .ToDictionary. The problem is, it tells me that it doesn't have sufficient parameters, to convert ToDictionary. So I need something like select FProducts.Serial_number, Nothing). ToDictionary. Also FProducts.Serial_number, 0).ToDictionary doesn't work.
Sub GetStatistics(ByVal ProductNumbers As List(Of String), ByRef Passed As Integer, ByRef FailedProducts As List(Of String))

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:
Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)
[Code]...
I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

This is giving me a headache. I have this link query here that grabs an ID
Dim mclassID = From x In db.SchoolClasses Where x.VisitDateID = _visitdateID Select x.ClassID And then later on I have this linq query
ViewData("Staff") = From t In db.Staffs Where t.ClassID = mclassID Select t
I've tried quite a few things but to no avail. I've attempted casting, converting, Is operand, etc.
