https://learn.microsoft.com/en-us/dotnet/api/system.windows.forms.timer?view=windowsdesktop-7.0

Timer Class (System.Windows.Forms)

Implements a timer that raises an event at user-defined intervals. This timer is optimized for use in Windows Forms applications and must be used in a window.

TheBoxyBear•2y ago

Add the timer to the form through the designer or add it as a member of the form and subscribe to its Tick event In the Tick event handler, change the image of the picturebox, or since you have buttons to change the image manually, create a NextImage method that can be called from the Tick and the Next button click

@TheBoxyBear HOW TO CALLED METHOD can you write the code? @TheBoxyBear thank you so much

TheBoxyBear•2y ago

void Foo()
{
  // Do stuff
}

// Inside another method
Foo();

void Foo()
{
  // Do stuff
}

// Inside another method
Foo();
