VS 2010 Randomize Alphanumeric "text" From Button 1 To Textbox 1
Jun 2, 2012I am currently working on a personal project. I have the template for my program layed out and now just need help with some codes to go in it. I've looked for codes online to give me a better understanding but have had no luck so far. What I would like to do is to be able to "randomize" a line of characters with only capital letters and numbers 0-9. I need the overall length to be 14, but realistically 17. The displayed characters would be in this form. XXXX-XXXXXX-XXXX, so the dashes would have to fall into that area with all other characters being random. I want it to link from the 1 buton to the 1 textbox.

How To Trim Non-alphanumeric Characters From A String

Game Programming :: Alphanumeric String Arrays
Jul 30, 2009I have a string array of size 51 CardListIn() representing randomly ordered cards in a deck {1d, 2d, ...14c} e.g. 9d = 9 of diamonds and so on. I then have 52 text boxes for user input. These have been put into an array of text boxes as so:[code...]
I want to search my original string array for any cards the user may input in any of the textboxes and then delete those entries from the string array.So say the user enters "1d" in one of the textboxes, I then want that removed from the string array.
I'm parsing through both the array and the text boxes fine, but for some reason that I cannot fathom, it doesn't find a match. The string array definitely contains "1d" and the textbox definitely contains "1d", but it doesn't register as a match. I've tried using Val() for the string array and the text boxes, but then it removes every entry beginning with a 1, e.g. "1d", "1h", "1c" & "1s".
