VS Display Integers Expanding 1.1 To 1.1000000000000001
Mar 1, 2011
This is, at least for me, most bizarre Visual Studio 2010 behavior ever. I'm working on MVC3 project, I copied a line of code from another project (VS2010 also, MVC1 if it matters) which looks like this: [Code] Now, if I type 1.2, it's fine, nothing happens, but if I type 1.12 it is expanded to 1.1200000000000001. Both target_height and height are integers. Why does one Visual Studio display 1.1 while other expands it to 1.1000000000000001? What is going on?

using for...next loop the program is supposed to accept 2 user inputed integers and display all even numbers between the two in one label and all odd numbers between in another label.
Private Sub displayButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles displayButton.Click
' displays the odd and even numbers between two integers
Dim intNum1 As Integer
[code]....
I'm not exactly sure what this code is doing. When I put 1 in the first number and 10 in the second number, the odd label only shows 9 and the even label only shows 10. Another example is when I put 2 and 15, the odd label comes out as 15 and the even label is 14. I'm very new to VB and programming in general and have just started getting into for...next loops and don't fully understand what the counter is or how the loop is supposed to work. I guess I'm having 2 problems. One is that I don't know how to make the program find the right numbers(my logic is off? or how I set up the loop isn't right?) and the other is the labels are showing only 1 number each instead of all the numbers in between on their own line.

I have written a program that generates and prints 10 random integers from -10 to 10, my problem is that I am returning both negative and positive numbers, aligned right with a pad of 2, but the negative is on the right hand side of my number instead of the left. here is my code, all work but I need to align the numbers and have the correct notation of negative.

My assignment was to Write a program to display a multiplication table for the integers from 1 to 4. So i did the code And got
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim n As Integer
[Code]....
The only problem with the code is that it displays only the integers 1 , 4, 9, and 16 when ran.

Basically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.

Iam trying to convert all my access database into Sql Server databases and also create vb .net application for them all. First problem I encountered was there doesn't seem to be anything like a continous form(I know there is a datagridview). So i thought i would create a flowlayoutpanel. Place lots of textboxes on it and fill each of textboxes with information form my dataset. now on to the problem. one of the textboxes is the item description field. This field can have one word or many words. I have been trying to get the textbox to auto expand in height to cover the text. Below is the code I have put together to try and get this to work correctly.
vb.net
Imports System.Runtime.InteropServices
Public Class Form1
Private Const EM_GETLINECOUNT As Integer = &HBA

I am trying to get a line to expand whilst the user hovers over a specific Label or Button, I thought the best way to do this would be using a however so far I cannot get the process to loop until the user stops hovering over the item.
Public Class Form1
Dim Sec As Integer
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Sec = Sec + 1
[code]....
That is pretty much what I have so far, it works however I have to keep hovering and then exiting the Label for the size to increase. I have tried various loops however most of them just end up in an infinite loop.Just to clarify, I would like the X2 dimension of the Line to increase until the user stops hovering over the form.

[code]i want to extend the window width everytime i expand the expander control to the right.when i run the above quoted xaml and expand the expander control after the build, everything works like expected, but as soon as i manually resize the window, the content of the expander control will expand into the existing area to the left. how can i change this behaviour, so that the window will extend its width to the right side and the content will end up in that new area?

I am developing a WinForm application using VB.NET (I am fluent in C# as well, so post in whatever language) and have run into some trouble. I have an image on my form that I would like to expand when clicked on. I have all that logic set, but I want that when it expands, the user has to click on an 'X' in the upper right corner of the PictureBox to close the expanded image. While the image is being displayed, I don't want the user to be able to interact with the rest of the UI on the form.
Basically I need something along the lines of (pardon me for switching to HTML but I know this works there) creating a div that covers the whole screen, making it opaque, putting another div on top of that, and then putting the image and the 'X' button on top of that. I have tried using opaque forms (didn't work), and panels with a transparent backcolor (didn't work either). I've resorted to taking a screenshot of the form, setting it as the image of a PictureBox, and putting the PictureBox on top of that. However, that seems like way to much overkill.
My current layout is MainForm -> Dynamically create new Form and add it to Main Form -> Add PictureBox to Dynamic Form and set its image to be a screenshot of MainForm -> Add a PictureBox on top of that PictureBox and set its image to the expanded image that I want

I do have a TreeView inside a splitterpanel-control. After executing the ExpandAll()-Method, a scrollbar appears on the panel and the first nodes are no longer visible, because the panel scrolled down to the bottom-nodes. How do scroll back to the top-nodes programmatically, because I want the user to see the first nodes on the top?

I'd like to design a Winform with expanding controls if that 's overly complicated. The idea is that I would have rows of information, each with an "Expand" button. On pressing the button, the rows underneath the selected row would move down and the controls that are associated with the selected row (some textboxes/ dropdowns etc) would appear. Vice versa when you click the "Hide" button.

The First Question is not that important but you know that when you click on 'Favorites' in IE 8 a form thing comes up? Well I've been trying to do that for a long time but I can't figure out how. 2: In IE8 when you expand the window and collapse the window, the toolbars expand and collapse as well. How do I make my tool bars in my Web Browser do that. 3: I actually have a third question and that's, How do you make a horizantal scroll bar on your web browser control. (just like in Internet Explorer.)

So I am making a file crypter so that I can encrypt my VB.NET Application that I am making so that people can't decompile it. I had made this in C# and am transfering it to VB.NET, Everything worked fine in C# but once I had re-written the code in VB.NET i get this error inside of my RC4 Encryption method:
'Arithmetic operation resulted in an overflow.'
The error is occuring here:
Dim t As Int64 = (s(i) + s(j)) Mod 256
This is the same code above in c#:
int t = (s[i] + s[j]) % 256;
Is there anyway to make that calculation with it erroring? And why does it work in C# but not VB.NET?

I have a group of 25 labels named Label1, Label2, Label3, ... Label25 in a square of 5 per row, 5 per column and I wanted to assign the backcolor to all of them on a loop and assign a value of "True" or "False" to a matrix of 25 boolean values representing them.
But I was getting errors on the pattern created.
My approach was to use a substring containing a number copied from the label names:
Num = Val(sender.name.substring(5))
And the subindexes of the matrix:
p = (Num - 1) / 5
q = (Num - 1) Mod 5
The values for the lower corner of the matrix were rouded to 5 instead of being 4. Instead of (4,0) ,(4,1), (4,2), (4,3) (4,4) I was getting (5,0),(5,1)...(5,5)
So I solved the problem by creating two single variables "A" and "B", doing the divission and MOD operations on them, finding the floor of them and then converting to integer:
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, _
