I'm trying to make a program in vb 2008 that is like a Quiz that reads questions from a different file and displays them in a label in the program. The program also reads 4 multiple choice into radio buttons. There is a next button that switches the answers and questions (reads them from a file) and displays them onto a label.

View 2 RepliesA text file exists on my server machine which is constantly being updated (about once about 5 seconds). On my web page, I'd like a div to display this file live using jQuery inside MVC.
I have the jQuery timer working already, but the file isn't displaying. My plan was to get the jQuery to load a Controller Action every 5 seconds and have this action return a FilePathResult.
The script:
$(function () {
var streamer = $("div.wrapper div.streamer");
//===
[Code]....
LiveStreamPath contains the path to the text file. I was thinking of creating a StreamReader in the Action instead. What sorts of implementations can I use to get this file to stream?
I have a 'next' button which changes the questions when clicked.

i want some work with swf. the steps are: all these things i will do with desktop application
1) break the swf file in small parts and store in any database or put these parts on physical path but in that case all swf part should be encrypted so nobody run these files with click.
2) run that parts from memory ( any of these part is not run with mouse double click ) with vb.net application
i read delphi can do the streaming of swf. so can it possible with .net
I have this problem in VB.NET in c#, I have this project where I need to run a batch file, which is easy enough. But my problem is I need to display everything that shows up on the batch file, in the cmd window, in a textbox, now, this code opens the file no problem:
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.EnableRaisingEvents = false
proc.StartInfo.FileName = "C:\Users\jwoow\Desktop\Server\run.bat";
proc.Start().ToString();
but it doesn't move the code over to the textbox, this code transfers the last displayed line, but not the entire thing of the batch file and it also closes the cmd window, i need it to stay open:
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
[code]....
the batch file is for a server, it displays the amt of users on it (updates ever 2 minutes) and shows different events taken by the users. so it is constantly updating.

I have made a screensaver in VB.NET. I am running into some roadblocks in the code though. The idea first was to have a ball bounce across my screens. It then evolved into spawning new balls that bounce across the screen. I then added collision detection so they would bounce off each other. Here is the problem that came up:
When said balls overlap each other, you can easily distinguish the edges of the picturebox that holds the images. I have made the background of the picturebox transparent, made the bitmap with a magenta background and made magenta transparent (for the image), but I can still see the picturebox edges when they overlap. It seems the transparency is not only making the background transparent, but giving it X-RAY vision to display not the visible area behind it, but the root background color of the form. here is a sample of the code which makes the transparencies.
Private Sub frmscr_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim bmp As Bitmap = My.Resources._smiley_face_image
Dim clr As Color = Color.FromArgb(255, 0, 128)
bmp.MakeTransparent(clr)
[code].....
I also tried to see if changing the image from background to foreground would help...no such luck.
I am making a game on vb.net. It is like a quiz game. In the game there is a button which when pressed pops up a question. The code for the input box is as follows:

Iam doing a project in vb2008 for a quiz program. i want to randomly generate questions in a textbox a question should occur once in the quiz session. i had my code:

I'm trying to make a quiz application with Visual Basic at the moment. I want to write a routine that asks five questions to which the answer must be either Yes or No. It must add up the number of Nos and if the number of Ns is less than two then print out "pessimist", otherwise print out "optimist". So far this is the design of what I've done. [URL]. However, I have no code which I've produced on my own.

Public Class Form1
Inherits System.Windows.Forms.Form
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I really don't know how I can kind of add up all the results from each individual question, seeing as radio buttons are used.
I am in the process of creating an array for a set of multiple choice questions but I am having a few problems. I am an absolute beginner at VB and I am creating a quiz that users will select one of three possible questions and then depending on their answer a +1 value will be added to the score. However I do not know where my questions and answers are supposed to go, from what I have read online I have to use (0, 1) format to give possible answers but I do not know how I would make the questions and answers display in textboxes on my form. At the bottom of my code I have also included code to randomise the questions although I am unsure as to if it is correct. At the moment I can run my form fine without any problems but my main issue is to how I will get the questions and answers linked to my textboxes on my form.
Public Class frmTest
Private ran As Random = New Random()
Public intScore As Integer
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
'Turns the message box invisible when start is clicked

I need to create a questionnaire with ten questions. The questions can be hard coded as labels. I will have a radio group box for each question, with options, Always, Usually, Sometimes, Seldom and Never. I will then need to store these values for each time that the questionnaire is answered, and another button that will show the question number and the answer count for each question up to that point in time e.g. [Code] I am also assuming I will have a button that when clicked, will identify the active radio button and add 1 to a counter?

I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
A while ago I wrote a quick and very very simple program to test myself on about 10 questions I needed to remember the answer to. I made a form with a label, text box and button. the label contained the question and the answer was entered into the textbox and the button was pressed to check the answer. the code i used was very similar to this:[code] Because I only had 10 questions it was fine to copy and paste the code a few times and rename the questions but now i am going to use this again but for a lot more questions (in the end there will be a couple of hundred) so i was wondering if any one knew a better way to do this? I was thinking maybe an array like 1 to hold the questions and 1 to hold the answers but i haven't worked much with arrays so I'm not sure how difficult this would be ?

I have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.
I use this code :
Dim name As String = Path.GetFileName(filePath).Replace(".Bak", "")
Dim source() As Byte = System.IO.File.ReadAllBytes(filePath)
Dim compressed() As Byte = ConvertToByteArray(source)
System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)
Or using this code :
Public Sub cmdCompressFile(ByVal FileName As String)
'Stream object that reads file contents
Dim streamObj As Stream = New StreamReader(FileName).BaseStream

I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
My.Computer.FileSystem.RenameFile("Test Flowchart1.dwg", "Test~Flowchart1.dwg")
