Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

I am writing a program to calculate Pi to several hundred billion decimal places and this will require lots of GB of memory. I wrote a test program in VB2008 that saved the first 16 digits of Pi (without the decimal point) to both a text file and a random access file, just to be sure it was outputting the numbers properly. For reference the first 16 digits of Pi are:

View 5 RepliesI have a text file that includes a list of first names, each on their own separate line.
What I am trying to do is to find a way to click on my button and have my app open the list and randomly grab a name and place it into a textbox.

I have learnt how to create a basic random word generator. I now want to take this further but I would like to know if what I am thinking of is possible. I am in the process of wanting to create a random name/word generator which reads/loads an array from a text file. think this part I will be Ok with as there are some vids and tutorials about. However, I wish for the text file to have multiple arrays and then dependant on the day and time of the day, only a string from the current time array is loaded. Does that make sense and is it possible? I am happy to spend time learning how to do this but only if it is possible.
