I'm trying to make a minesweeper game using visual basic forms. I have made the tiles by making each one a separate button. I have made an array of Boolean values to decide which buttons have mines. I am stuck because I can't figure out how to pass variables through the event handler. I also don't know how to make changes to the button within the subroutine that is called with the button click event handler.
I would appreciate any help anyone can offer.
Thanks a lot!
The documentation explains how to send an action to self however I can't find how to send an action to another component. Right now I'm putting all of my app in a single big reducerComponent but I'd really like to be able to have a menu component with some buttons and an other component for the main game area and have the buttons change the state of the main game area.
It's very similar to React and well described in Thinking in React as
React is all about one-way data flow down the component hierarchy. It may not be immediately clear which component should own what state. This is often the most challenging part for newcomers to understand...
You should pass both handler and the state down to children from parent components. Good example can be found here.
I have a user control defined in a separate project (To reuse) which has two comboboxes and a button. I will be using this user control in other projects. The user control has a view model class. This view model class handles selected item changed in the combobox and also has a command delegate to handle the button click.
Now my question is when I use this user control within another control in another project I want an event to be raised within this owning control as well whenever a new item is selected in the combobox. Also, when a button is clicked in the resuable control I want that event to be raised in my owning control as well so that I can execute some additional logic. Can somebody suggest which is the best way to handle this?
Thanks,

Hello I have a prism/mvvm style application and am using the RadMenu control. I also have a view/view model pair in one project and another view/view model pair for my RadMenu control in another project. Basically I would like to use the event aggregator to send an event to the view model for the RadMenu (the view model that is paired with the view that the RadMenu sits inside of). So that the RadMenu's view model can notify the RadMenu to switch to a different RadMenuItem programmatically. I think I can use a blend behavior to contain the behavior I'm looking to reproduce, but I cannot find a method in the RadMenu that will allow me to programmatically select a specific menu item.
If the control does not support this now, is there a work around? Thanks.
I believe this is a missunderstanding. As far as I know there is no selection on the RadMenu. You can only Check or Uncheck Items in your Menus. Are you trying to emulate a user clicking on a specific item just to trigger the functionality behind the menu-item? If that's the case I would propose another way and directly handle the EA-Message in the ViewModel. You can trigger the code from there then. If you're doing MVVM the logic behind the menu-items is implented in your VM anyways. :)
For my project when a button is clicked, the click event should then wait and listen to the next two clicks on different widgets and then connect them so as to form relationship between them.
Right now i an trying to use FocusListener without success. Any suggestion will be of great help.
Thank you.
I would think you'd just want an ClickListener for each object. Handle "enabling" the other two objects in the first object's click event, then when those two objects are clicked on, invoke the method to form the relationship. You don't want to wait in the first object's event handler.
