  Hello again everyone,
  
  its been a while lol ope evryone is ok, i have a question regarding building a menu at runtime froma txt file. I have been asked to create a button set ie 6 buttons that get there name.text and there event handler from a txt file, so that the 6 buttons can be changed dynamically.
  
  As far as im awar a normal menu that is built at runtime is created by using event handlers the button calls the method and then executes the event.
  
  Does anyone have any solid ideas of how i can create my dynamic button menu using a txt file?
  
  Mant Thanks

  Getting the text to display on a Button from a text file is quite reasonable because the Text property is type String.  I don't see how you can specify an event handler in a text file though.  An event handler is a method and the available methods are compiled into the application.  How can you pass in an event handler from a text file?

  Its a horrible hack, but if the possible event handlers are documented, its possible.

  Assume you have 3 handlers:

  DoCalc

  DoWrite

  DoRead

   

  What you do is create a button on the fly, or 'make visible' one or more of 6 buttons that already exist on your form.

  In their Click event, just use a select ... case statement to check which event handler you want to use.

  select case strEvenet

  case "Calc"

  call DoCalc()

  case "Write"

  call DoWrite()

  ...etc
