I am trying to make a Christmas light animation via computer control. I am using VB.Net and have tried several examples I have found, but I get the same error: port is closed. The code I am using is this:
Imports System.IO.Ports
Public Class Form1
Dim instance As New SerialPort
[Code].....
I have tried several things and I still get the error message that the port is closed.
I'm trying to make a USB strobe light type thing. I have a cut USB cord with an led attached to the black and red wires. Now I'm trying to write a script to make the light flash on and off really fast. I've tried several different apis but none are doing it.

View 1 RepliesI'm trying to make a light version of a Blackjack game. The rules I need to use are as follows:
Ace = 1
Normal Cards = 2-10
Color Cards (king, queen, etc,) = 11
The dealer can keep hitting until it reaches 17 or under 21, he must always stay once it hits 17 or over (without busting obviously).
I know the ace normally should be 1 or 11 normally but I don't want to complicate things, I want to get the main thing of the program working first.

I'm making this rubik's cube program, and I wanted to make a 3d animation of the cube doing the moves, and I figured the best option for that was using the XNA extension. However, doing that brings up a problem. I want to have lots of different options in the Mdi parent form that will interact with the moving 3d cube. The problem with this and using XNA is I can't use both the normal form and the XNA game in the same project. How would I go about having the 2 different projects interact? Just like a txt file or something?
View 1 RepliesI want to ask, how i can make animation only with 1 images, inside there are like few different images. I seen this in few games, and i want to try it. I think there should by picturebox and it should scroll my animation right with timer, by few pixels. Image example: [URL]

View 2 RepliesI am using an webservice to update my dataset and have a picture box to show an processing image i.e. a gif showing a progress bar and the words processing. My prob. is the gif stops animation as soon as the control goes to the webserver. I have done this.
Timer1.Enabled = True
Timer1_Tick(Nothing, Nothing)
picServer.Refresh()
GetMasterData()
In the timer1_tick even too I have tried picserver.refresh (picserver is the picture box). Getmasterdata is the process where the data is returned from the web service and as the control goes to the web service it somehow stops the process of the gif. It takes about 5 mins to popup the data from the webservice this code is in the form load event of the main form.
I've been trying to make basically a simple animation player inside a class so that I can use it in a game I have to make for a school IPT project. When I first tested out some code I found, it was not in "class form", ie there were just loose variables as I was only animating a single .gif file. The code worked perfectly, and the animation was drawn frame by frame by the e.Graphics.DrawImage function.
Now that I have moved the code into a class (So I can run more than one animation at a time, though Im still trying to get only one to work), The e.Graphics.DrawImage function didnt work. It would draw the first image, but then (even though the function is called as shown by stepping through the lines of code), the picture doesn't update. I know the frame has changed as Ive kept track of the current frame in the debug window, but it still wont work.
I have had troubles like this with other GDI functions, where if the variable to draw is inside a class (etc) it simply wont work, it will only work if it is a loosely floating variable. (i.e. Sprite.Image doesnt work, If I just make an image it does). With the code below, I have tried in the e.Graphics.DrawImage function submitting me.wth.animatedImage and wth.animatedImage
Public Class Form1
Dim wth As New vsprite

Public animatedImage As New Bitmap("C:Documents and SettingsSamDesktopexplosion.gif")

I am using a Gif animation on my Mainform. When i open a second form and then return to the mainform - the animation stops. How can i make sure that the animation restarts after the second form was closed?

View 14 RepliesI am in the process of designing a computer control program to control a HF communications receiver (radio), and have found a problem with the Serial port. I am using VB Express Edition 2008. This module of the program is supposed to take an input string from another part of the program, format it, break it into 4 bytes, and send it to the radio in hex form via COM port 1. The problem comes in when you try to enter a frequency with an 8 or a 9 in it. The 8 or 9 is usually replaced by 45, ex.-input 9900, receiver tune 4545. The exact same thing happens with 8's, input 8800 and receiver tune 4545. All other numbers other than 8 or 9 work fine. The strange part of it is that sometimes the 8's and 9's work, and work correctly. For instance, 900, 1900, 2900, 3900, 4900, 5900, 6900, and 7900 all work correctly. This led me to believe that is may only be when the 8 or 9 is in the first position, but that is not the case, it also shows up in other positions as well. All other frequencies that do not have 8 or 9 in them also work. I ran into this same problem with VB Express 2005, and worked on it for weeks before giving up and going back to VB6.0. This same module (with exception of the port open command) runs flawlessly under VB6. I have even tried importing the MSCOMM control from VB6, but it gives the same results. In de-bugging mode, all of the inputs, decimal and hex seem to be correct, so the problem must come in after you click the command button, but before it leaves the COM port.

View 1 RepliesSimulate a traffic light with three small square text boxes on the form. Initially the bottom text box is green, the rest are dark gray. When the tab key is pressed, the middle box turns yellow and the bottom box turns dark gray. The next time the tab is pressed, the top box turns red and the middle box turns dark gray. Subsequent pressing of the tab key cycles through the three colors. Hint: First place the bottom text box on the form, then the middle, then the top. I did all this and dabbled below. Does that look at all correct...minus the timer thing...I got the timer code (which is not needed) but am not sure how to write it so the tab key does the work. This is really confusing to me, but it is a required class.

Simulate a traffic light with three text boxes placed vertically on a form. initially, the bottom text box is solid green and the other text boxes are dark grey. when the tab key is pressed, the middle text box turns yellow and bottem box turns dark grey. next time the tab key is pressed, the top box turns red and the bottem two turn dark grey. Basically the tab key cycles through the colors.First off let me say im not looking for an entire code.

I am supposed to be writing a program for my instructor using VB 2008. It is sort of like a quiz program. You build the "light bulb" program but instead of names and colors, it consists of two forms. Question 1 with a "next" button and the second form for Question 2 with a "previous" button. I have no idea how to link the two so that when you click "next" it goes to the second page and vice versa.

View 3 RepliesWhen I downloaded VB 2005 Express I took advantage of the bundle of goodies on offer and downloaded SkinCrafter Light.I really like the four skins that come with SkinCrafter Light, and I am using one on my current project (example of the skin I am using here). However, SkinCrafter Light has a couple of bugs with RichTextBoxes (these bugs are known to SkinCrafter, as I can see posts about them in their forum, but they have gone unanswered in over two years!)One bug is that any text that is colored in a RichTextBox is turned back to black when the skin is applied, and if you click anywhere in the RTB the application will crash (you can see my RTB on the right bottom of the form in my screenshot above).
I use colored text in my RTB, but, at a pinch,I could make do without (as I really DO like the Skin), but the problem remains of crashing when clicking inside a RTB.I was wondering (can't test at the moment as I am at work) if simply placing a control, such as a Button, Label, Picture box etc, set to transparent, over the top of the RTB, would solve the problem, so a user could not click inside the RTB (but would be clicking on the invisible control over the top instead).

View 2 RepliesI am trying to do is to draw a ray of light emitted by a light source and it is going to be reflected mirrors. I rotate the emitter and mirrors and the ray of light shold obey the laws of reflection. The emitter and mirrors are in an opaque room which means light should not go out. Where I am now is that I am able to draw the ray but when the angle is 90 degrees ( +or-) all the drawing disappears. I set some conditions to make up for this situation, but it does not seem to work. Besides if the angle exceeds 90 degrees, the line is drawn in the opposite direction.One other thing that happens is I set the ray to stop when either end_x_emitter_ray or end_y_emitter_ray = 500. It works for the end_x_emitter_ray but not for the end_y_emitter_ray[end_x_emitter_ray and end_y_emitter_ray are the point where the ray end]I have uploaded the my whole code here. Can you guys suggest me what can be done to make it work appropriately?
