I know I've asked this once, but it was deleted for some reason. But I should do that if you write two numbers in TextBox1, then add a colon, and if you write two more, one more colon, and then you can only write two numbers if you typed the numbers. eg: type "12" then the program puts a ":" so it will be "12:" then write two more numbers eg "45" it will be "12:45:" and after that you can only write 2 numbers eg "26" will be "12:45:26" and you can't write more than 24 in the first place and more than 60 for the other two. Please describe what should be written and where? or if a program written in an existing Visual BAisc programming language can be converted to ec # somehow? thanks in advance for the answers!
