问题 Has C# indexed control arrays or not? I would like to put a "button array" for example with 5 buttons which use just one event handler which handles the index of all this 5 controls (like VB6 does).

问题 Before I begin, I have researched and can't seem to find anything. Note I am very new to UserControl so this might be why it's proven difficult. I have a combobox in Form1 which when selected allows the user to change between a choice of 21 languages. I have created a UserControl that contains labels, buttons and checkboxes - adds to a form called Print. If a user selected French, how would I then implement the UserControl to change language for ALL forms in my project? UserControl: I have

问题 I have several textboxes , i want the cursor to move from one textbox to another using arrow keys. how can i do that? it looks like this, also the tap moves vertically which is weird.

问题 I have a user control that I'm building. It's purpose is to display the status of a class to the user. Obviously, this does not matter, and will slow things down when the control runs in the IDE, as it does as soon as you add it to a form. One way to work around this would be to have the control created and added to the controls collection of the form at run-time. But this seems less than perfect. Is there a way to set a flag in the control so that it can skip certain sections of code based
