I am using the following code to create an array consisting of double values specified by start stop and step. The problem with that is that for some weird reason there is a calculation error that seems to originate from the for statement causing the values to drift after the 11th to 12th digit after the comma which is quite irritating for the purpose i am using it.

As Strings.Space Method , but instead space - new lines.For example:If I want 4 spaces, I can do:
space ("4")
But if I want 4 new lines,I have to do?:
VbNewLine & vbNewLine & vbNewLine & vbNewLine
Or there is another way and more effective? (such as "Strings.Space Method"for example)
I need to set up a list consisting of arrays of two elements. Simple, right?
Like: (code snippet):

I am trying to create a form which will be fed by an underlying database to create multiple form fields for each entry in an underlying database table. This is for a program to monitor patients under anesthesia, and prior to surgery, the doctor will choose which monitors they will be using. Then, on the actual monitor screen which will pop up every X minutes, there will be a text box and a check box for each chosen monitor. I am relatively new to VB, so I have tried to illustrate what I am needing but using the logic that I know from my previous life in PHP.
I am using DevExpress's layout control to place the form fields, so that is the code in the middle of the first loop (on_load), and I know that part works, I just need to know how to name the fields and then recover those fields and commit the values to the database. (the text boxes are added to the database, the check boxes are used to determine if an entry is made for that monitor- i.e. at the end of surgery if a monitor is turned off). I know that my syntax for naming the fields is no where close to correct, and it probably would not work in PHP, but I remember doing something like this in a PHP application I built long ago. [Code]

Is it a good idea create my components in C++ using images?
How do you create an array for images, specifically to develop a slot machine game so-to-speak. Because our class is using a really, really old version of Visual Basic (that is, VB 4.0...ick), I decided to move myself up in the ranks and play alongside and learn the newer software.I've mentioned arrays before if you recognize my screen name, but situations caused me to bump up again to 2010, so now I need some help reacquainting myself with the software.

I'm trying to accomplish is having a 20x20 pixel image show up multiple times as determined by the grid selected. To keep things simple, what I'm trying to do is create a 9x9 grid of a image onto a form. I'm assuming that a picture box is the way to go, but don't know how to make that happen or if it's even possible.
So it would go something like this:
2D array already assigned:
Sub ShowGrid()
For rw As Short = 0 To 8
[Code].....
But instead of using a text box with values, I want to show a grid of a small image file, like cup.png which is 20x20 pixels or whatever, so what would show up on the form in this case would be a 9x9 grid of the image file over and over to create a grid.
Then the next step I hope to accomplish is to have that 20x20 square picture hold the grid(x,y) value for a mouse click. So if the image at grid(3,5) is clicked, it will give me that value, 3-5.

View 2 RepliesThere is an IP web camera that I wrote a .NET class for sometime ago. It's basically a Timer implementation that pings a snapshot CGI script from the camera every five seconds. The camera itself is very rudamentary; it does not have any sort of API for me to work with, the only thing I can do programmatically (remotely) is invoke this script. The script returns a 640x480 JPEG image. Simple.
Now what I need to be able to do is take a days worth of these images, and create a "time lapse" AVI video stream out of it that will eventually be embedded into a web page. How can I do this with VB.NET?

View 3 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
