Below is a screenshot of the buttons that I want to take action when pressed when my program runs.
How can I make this work?
Just press control button from your keyboard and do the following:
And write your code into that action and it will run when you press the button at run time.

I have developed an application using VB.NET that uses a touchscreen (it's a Point of Sales app). I have used button click events to execute the code like a normal Windows application. Is this correct way to do it, or should I use MouseUp and MouseDown events?
Using Click events is correct. On a touch screen, tapping a button will generate a Click event, just like it would if you clicked the button with a mouse.
P.S. You mention in the comments that sometimes the application hangs when you click a button. This is most likely caused by the code that responds to the Click event, and is not related to using a touch screen.
Just ran into an issue on our Touch POS app yesterday. The click event is fired twice in some cases on some monitors. It seems that different touchscreen monitors handle the click even differently and some have software to prevent it others do not. The specific issue was that our click event was being fired two times so clicking button "1" would result in "11" Only happened when using the touchscreen not the mouse. The first depress of the button would put "1" and then when you took your finger off the button another "1" would appear. If you debugged the click event it would only be fired 1 time and just put 1 in the field. If you took debug out it went back to 11.
Save yourself the headaches and use MOUSEUP.
I have an application which has a button on the first window, once pressed this button should hide and perform an action, to hide the button i'm using this code:
[self.myButton setHidden:TRUE];
This works fine until I have multiple windows - new instances of this window do not have this button it's hidden by default. However when I create a new window and press the myButton on the first window it doesn't hide the button.
Furthermore if I create a new window and then close that window and press the myButton on the first and now only window it crashes.
Any ideas how to overcome this?
myButton is pointing to the button in the last window you opened
I add a button inside Tool Tip and handle the button click event.
and in run time I move the cursor to do click, the tool tip disappears.
my question is:
how can I do the tool tip don't disappear, so I can click the button inside it?
I have a simple Mac app with a window. In this window, I have two NSTextfields and one NSButton.
When the window appears, the first NSTextfield has the focus. I press enter and the focus passes to the second NSTextfield. I press enter again and the focus passes to my button.
[myWindow makeFirstResponder:myButton];
This works fine but now when I press enter again, I expect that the button is clicked, but it does not happen.
On a Mac, spacebar is what you press to select a button. This is the same for a selecting the value of a dropdown, radio button, or check button.
I have a button and inside my button I have an image control. When the users click on the image I'd like to animate the button so it appears the button was pressed. I don't really care whether the actual button press event fires or not--it's the illusion of a button press I want to see.
Note: the only options I see on the web involve writing directly to the Windows API--a level of complexity and non-upgradability I really don't want to get into.
Why not just use two different images, one for a normal state, and another for when your button is being pressed.
If you want to go for more complicated route try using GDI+. Here is a quick sample tutorial on how to do this.
Why are you using an image control inside your button control instead of using the button control's Image property?
Using the Image property of the button will give you a button with an image that the user can press and that will raise the OnClick event without doing any extra work or re-implementing features that are already available.
I ended up making my picturbox look like a button by giving it a raised border style. Then on the mouseclick event I simulate the look of a button press by changing the border style for a few hundred miliseconds.
Private Sub simulateButtonPress(ByRef pictureBox As Infragistics.Win.UltraWinEditors.UltraPictureBox)
pictureBox.BorderStyle = Infragistics.Win.UIElementBorderStyle.Inset
Application.DoEvents()
System.Threading.Thread.Sleep(400)
pictureBox.BorderStyle = Infragistics.Win.UIElementBorderStyle.Raised
Application.DoEvents()
End Sub
