I'm making a simple text game over the summer for something to do and was wondering if it's possible to change a buttons OnClick functions on the fly?
For example, if they enter a door I want to change the buttons OnClick to call a different subroutine instead of the one that's already predefined in the code.
What I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).
I need to create unit testing project for my current website. The currentw ebsite si written in VB. All unit testing examples are using interface to create mock object. My current VB class does not implment any interface. Can I add interface and implement it to my current class and functions without affecting or changing codes to any pages in my website that call the functions? For examples my current class is like:

I have reiseved this function on an previos thread but I dont know how to use functions. how do I get it to do its thing by for insance clicking a button?

Dim folder As String = My.Computer.FileSystem.SpecialDirectories.MyDocuments
[CODE]...
Is it possible to have a button do one action the first time it is clicked and a different action the next time it is clicked?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Button1.Hide()
Button2.Show()

I did a super simple calculator with ASP.net with five buttons: add, subtract, multiply, divide, clear. There are five separate functions for each button's click event. For example: Sub addfunction(ByVal s As Object, ByVal e As EventArgs)If Not IsNumeric(input1.Text) Or Not IsNumeric(input2.Text) Then resultLabel.Text = "You entered an invalid or missing number"
[Code]...
How might I be able to combine all 5 of these functions into one? So for example, all the onclicks will refer to the same function, but will somehow be able to determine which button was clicked? I forget a lot of VB.net from a year.
i've got buttons i'd like to highlight on mouseover. how does one change the image associated with a button?

I have been trying for about a hour to get this to work but I cant. Want to do is change the location of my button when I check my Checkbox I tried If CheckBox7.Checked = True Then Button3.Location = (100, 277) End If is this wrong? It seems like it should work but it doesn't.
View 4 RepliesI have a form which has ONLY three buttons. Somehow they got named Button5, Button6, and Button7.
When I try to rename them Button1, Button2 and Button3 to match code, I get a Dialog box which, if I look at Details, says the Button name is already in use.
Is there something I can do to enable the renaming?
I've used (buttonName).enabled = false to disable buttons when the user clicks on them but I don't like how the button becomes faded.
Is it possible to disable a button without changing the look of the button?
I made a code that will change the background button when the mouse cursor over it, the user press and release it ,and it work great.The code below is a part of the code I made, which will change the background of the button when click by user.
Method to use:
butclick(sender)
Sub butclick(ByVal butname)
'code reset of button background start
Main.bestassi_bluebut_about.BackgroundImage = My.Resources.buttonbg
[code]....
But I had to reset all of the background of the button first, the picture below explain why I need to do like this:
BEFORE ALL BUTTON CLICKED BY USER:
IF NOT RESET AND ALL BUTTON CLICKED BY USER:
IF WITH RESET:
So is there any better code for this? Because my method seen a bit silly. Is there any code that can change the background of all the button in one time?
Although my code compiles, it does not result in a change of the background picture of button1 here is my current code. Is it possible that my condition contains some error? or is the command itself wrong? [code]
View 1 RepliesI have a problem with my program. I have a form with 2 buttons UP and DOWN. I use this buttons to change the size of the form. The first step works fine. If I press the down button I get MsgBox ("Go Down", vbYesNo,) if I press Yes the form resize from 300 to 600 and if I press no it stay 300. The problem is, if the form is already at 600 everytime I press the down button I get the MsgBox ("Go Down", vbYesNo,) if I press Yes it recycles it self the form goes to 300 and then back to 600 and if I press No it stays 600. What I want is if the form is already 600 and I press the down button it skips the MsgBox ("Go Down", vbYesNo,) and the form stay at 600.
Public Class Form1
Private Sub ButtonUp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonUp.Click
Dim answer As String
If Val(TextBox1.Text) < 0 Then
answer = MsgBox("Go Up", vbYesNo, )
If answer = vbYes Then
For x = 300 To 600

I have a button click handler that is coded. I typed in a new line of code without any errors, but the new line of code does not execute. To troubleshoot, I tried to add a simple message box, commented out the code, and deleted the entire code. With everything I try, even deleting the code, the original code exectutes at run time. I can't find any other instance of the code anywhere else in the application. Other events update normally.
I gather the code is either not updated upon build/compile, or this bit of code is stored somewhere.
I got a Combobox with some items (item1-item7) to select and 54ish Buttons(sButton1-sButton54). Also an array(53) called Buttons. The array is filled with the items to select, like: Buttons(0) = "item 1, item 2" Everytime another item in the Combobox is selected, I'd like only some of the Buttons to change their Image. Therefore I got the array. If Item 1 is selected and Buttons(0) contains the item1 I'd like to change the Button1's image.edit: It works with changing the image of every Button:
sButton1.Image = My.Resources.image1
But I'd prefer to change all in one go (Loop) instead.
sButton(0) = "item1, item2, item3"
sButton(1) = "item2, item3"
sButton(2) = "item1, item3"

I am working with buttons I have A treeview that when you click on a node it changes the text in textboxes and I need it to change the command the button does. So when a user clicks a node it changes text in 3 text boxes and changes the download link for the button. As you can see from the code all works fine but I need to use a button to download stuff and I dont know how the download code is
My.Computer.Network.DownloadFile _
("[URL]", _
cookiepack)
MsgBox("done")
That's what I need the button to do
Private Sub TreeView1_NodeMouseClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Dim filePath As String
filePath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)

I have a form with buttons, and the user can change the colors of the buttons with the color dialog box for fun:
Button_Play.BackColor = ColorDialog.Color
There is a reset button to put the colors to how they were without any special coloring, but I can't get them to go back to how they originally looked.They go to gray in the middle, instead of the nice shaded blue/gray style. I have tried a few different things:
Button_Play.BackColor = Button.DefaultBackColor
Button_Play.BackColor = SystemColors.Control
Button_Play.BackColor = Color.Empty
I am using VB '08 Express on Win XP with the Desktop, Display Properties, Appearance, Windows and Buttons: set to Media Center Style and Color Scheme: set to Energy Blue. how to (with this theme) get the button to look like default after changing the color?
I have a web application where I built a wizard, going from panel to panel.Besides using the Next, Previous buttons, one can use the Side Bar to select what panel to go to.The problem is that while the selected Panel's side bar button is Highlighted / Bolded, it is barely discernable to my client.Not only do they want the button highlighted, but they want the (selected) side bar button to change color as well.
