command

问题 I would like to ask for your help on the following issue in MS Access. I had created a form "CustomerListF", filled with command buttons for each client. For each button, I had created the following code: Private Sub cmd_outlets_ABC_Click() DoCmd.OpenForm "OrderFormF" Forms!OrderFormF!Outlets = "ABC" End Sub The button would then open another form "OrderFormF" and enter "ABC" in the textbox named "Outlets". However, I realized the second line of code (Forms!OrderFormF!Outlets = "ABC") would

问题 I am trying to parse a command in shell, and in one of the options I want to save in a variable if a string has "r" , "w" , "x" , one of those, all of them, or a mix, but only these three.

问题 I'm using tkinter to create a 8x8 button matrix, which when the individual buttons are pressed add to a final list (eg finalList = ((0,0),(5,7),(6,6), ...), allowing me to quickly create 8x8 (x,y) co-ordinate images. I have created the window with the buttons but now have issues trying to reference these buttons in a function to add to a list or even change the colour of the button I have read that once the button is created and you create another it moves to that button reference. I suspect

问题 I have the following code snippet, with my question below. As i am completely new to unix, i am not even sure what i should be google searching for to begin with.

问题 I'm creating a gem in which I would like to be able to make a shell command performing a function in the gem. In a more simple context, I need to create a shell script that performs a Ruby function with options when the shell command is triggered. What is a easiest way to do this?

If I could, I would also like support for common 'options' formatting in the shell: $ cow
