Get Randomly Generated Image On The PicBox
Nov 18, 2009
I have two images on my VB pictureBox one of it is randomly generated on the picBox(to any location) and the other is a normal image that can move around the picBox area using left right up and down buttons. The problem is that when ever the normal picture gets to the random one, it goes under the random picture and the task is to restrict the normal picture from going into the walls of the random one. when it gets to the wall, top, bottom left and right, it should stop moving.

Below is a form which produces a graph, the idea is to produce 6 random numbers from a range (0,6) place the numbers in an array then use these numbers to produce columns on the graph, however at the moment it is using the numbers more than once, how can I get it to just use the values once only in the array.
Private Sub btnGraph_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGraph.Click
txtAns.Text = ""
g.Clear(Me.BackColor)
g.DrawLine(Pens.Black, 50, 70, 50, 420)

I am setting up a game for my final visual basic program in my computer programming class, and it is supposed to compare what you type into a textbox to a randomly generated password, and then return whether the last character you entered had a higher, lower or the exact same ascii value as the corresponding character in the randomly generated password. Well, in order to test it, I set up labels to compare the two characters... when you type in ALT + 125, the ascii value returns 125, as it should, and it says that the ascii value of the correct character is 142. I typed in ALT + 142, and the character's ascii value, according to what the label puts out, is 196... obviously its converting dec into hex or oct or something... but how do I fix it?I can also tell you that when I typed in 196 to see if it was reversed or something stupid like that, it printed that the ascii value was 49... what's up with that?!

In a project I'm working on, I've assigned each user a unique ID with the following code. [code] However, I want to replace the number at the end (RecordCount) with a randomly generated sequence of 4 numbers (no 2 can be the same).

Basically I am trying to get my timer to stop when it reaches a randomly generated number.
I have dimmed num2 as integer (num2 is timer)
I have dimmed num3 as integer (num 3 is random number)
I have done num3 = randNum.Next (0, 8)
My timer is working perfectly and counts from 0 -8. My randomly generated number works too, so how do i get the timer to stop when it reaches the random num?
I have tried;
if num2 = num3 then
timer1.enabled = false
But that didn't work

My program is supposed to display a randomly generated sentence on the screen (something like a screensaver) Then 'wait' for a random period between 1 and 5 minutes before cycling through to generate another sentence. How do I do that?

Basically, I'm not sure if I'm thinking along the correct lines when trying to break this down. The program is supposed to display the question "How much is _ x _?" with _ being a randomly generated number between 0-9 which I have in a label. The student inputs the answer and clicks the "Answer" button. If he gets it right, the label below outputs "Very Good!" and automatically puts a new question in the above label. If the student gets it incorrect, the output is "No, Please try again." and the student keeps trying until the question is answered correctly.
My method of thinking on this is that the random.object generator is input first so the question with the numbers are output in the first label. Then, under the Sub answer.button, enter the statements that will either check and refer to the above statements to get a new question or have the student try again until it's answered correctly. One of the other criteria for this is that I have to use a function for the calculation. Would the function statement, because it has to return a value, go before the answer.button code or after?

I am going to create a windows form and add a push button (pretty simple right?) I want the push button to randomly cycle through about 10 pictures and display the randomly selected picture.
A few problems I am facing, 1) I do not know how to do do "randomization" in VB.Net and 2) I do not know how VB.Net would handle displaying an image, would it display on the form i am building or would it display in the default photo viewer for Windows?

I am currently working on a project on Microsoft Visual Basic 2008 Express Edition, in which I need to move an image across the form from one end to the other without moving it in a straight line. I want to try and randomize the image while it moves in a general direction, but I am not sure how. I also am trying to get four images to do this, from top to bottom, bottom up, left to right, and right to left.

I have a graphics application that uses graphics paths. Code seen below. You can use keyboard characters to display information. When a label is set to visible = false after being turned on for a number of seconds a stray image is generated. The stray images are also sometimes generated when the label is first made visible.
' points p10b, p2b etc are defined elsewhere
Dim GrpPoints As PointF() = {p10b, p2b, p3b, p11b, p5b, p6b, p12b}
GrPath = New GraphicsPath ' 7 path points
GrPath.AddBeziers(GrpPoints)
[code]....
I tried stopping the code from running when the label is set to visible = false but the stray image is still generated but just later. If you want more information let me know.The white arrows points to the stray image that is created just after a label that displayed information was set to visible = false

I have several picture boxes on a form (frmMain).My question is, how do I paint a point on a particular picture box at the location specified by the coordinates of the current mouse position? The snippet below shows defining some canvases and pens. But I'm not sure how to capture the mouse position when the mouse is over a particular picture box and how to paint the actual point at that location.[code]

Clicking on the picture will cause the picture to move in the following manner: * If the picture is in the top left corner, it will move to the center, then to the top right corner * If the picture is in the top right corner, it will move to the center, then to the lower right corner * If the picture is in the bottom right corner, it will move to the center, then to the bottom left corner * If the picture is in the bottom left corner, it will move to the center, then to the top left corner

Our solution is built on ASP.NET v1.1 framework. User is presented with login form, so upon providing credentials this information is posted back to the server. Upon postback SessionID changes and our application crashes as some information which is required for processing is stored in the cache and is identified by SessionID string as a part of the name.
This SessionID change happens absolutely randomly and only to some of the clients. Most of the time browser used to view the page and post info is IE8. I cannot reproduce this issue in our test environment, as SessionID is persistent though-out the whole testing process.
I've already checked all solutions, i.e.
Session cache is used on Page_Load to retrieve/store some information, so it's initialized and contains data stored. I've made a Health Monitoring check on Application_End event to capture any possible AppDomain crashes using Reflection and Diagnostics Libraries and retrieving ShutDownMessage from httpruntime object, but that's also not a case. Cookieless attribute of the sessionState in web.config is set to false (using URL to store SessionID is not an option)
All MS security and bug fixes are installed on the server. IIS Server settings are similar to the ones we use in Test Environment.

StartProcess()

I can run this 100 times under the exact same conditions and it seems like 40 times it will crash with the following error:
"Cannot access a disposed object. Object name: 'frmImportExport'."
It will either die on
'within StartProcess()
Dim __Delegate As New _Delegate(AddressOf StartProcess)
Me.Invoke(__Delegate)
or
Dim D As New _Delegate(AddressOf SOPERATION)
The form isn't being disposed manually anywhere that I see, and this code is being executed on formload. It's a subform that is to be displayed within a main form.
