View 5 RepliesSine Wave Using Timer Component?
Feb 28, 2011[URL]..I wrote a program with a timer set to tick every 100 ms. The values oscillate between 109 and 110 ms. Each tick, a variable adds +1 to itself; it starts at 0 and goes to 9 and then it goes back to 0 where it continues the addition process. When the timer ticks 110, the variables is added to a textbox. The pattern is something like this, which you can see in the above youtube video. 5 9 5 9 5 9 4 8 4 8 4 8 3 7 3 7 3 7 etc.

View 9 RepliesHow To Create Random Name Generator - DataBinding
Apr 24, 2009I'm trying to create a random name generator, and in order to store all the names I'm using an SQL database. I've got the database set up (simple version just until I get it working) and here's basically what I want the program to do. My database consists of three main fields: Name, Gender, and Origin (along with corresponding ID's). I want the user to be able to use a drop down combo box to select the gender (m or f) and the origin (i.e. English, German, Chinese, etc.), have the program filter out any data not within these parameters, randomly choose one of the remaining names, and display it on the form in a label. I'm not quite sure how to get the combo boxes linked to the data set so that, when running, the chosen item filters the data.

View 1 RepliesCreate A Random Number Generator That Iterates Through A Series Of Number Between An Upper And Lower Bound?
Jun 24, 2010i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?
