I am trying to create a simple game for children for my final year project, I have a number of form that will display a different type of question for each form. I am aware of the form1.Show() and form1.Hide(), is there anyway that I can load a form on random. for e.g, lets say I have form1, form2, form3, form4.I want the order of the forms to be shown in random order.

View 11 RepliesI have a project with many forms on it, some of them are dialog forms, some of them are mdi children of my master form. What I need to do is when a user press the ESC button on his keyboard to dispose the form that is working on. either is mdi or dialog form. I know that I can use the event of the form key down and then check the key code if is the esc to dispose the form, but this is not I looking for since I will have to pass from all my forms and create that event. Is there any other way when my master form is load to create my own event for any form load event? And trigger it from there to assigne my custom code for ESC key. So I will not have to pass from all the forms to create that event.
View 8 RepliesI have a form that opens another. I want the second form's checkbox to match the first form's after the second has loaded. I tried using MyForm2_Load, MyForm2_Activated and MyForm2_Shown but the checkbox checked state of the second form always changes the checkbox in first form. The code below works if I check the checkbox in either form, the other changes to match it. The problem occurs only when MyForm2 is first loaded. How can I get it to work the way I want it?

View 13 RepliesI have a form with an Adobe PDF reader control. I point to a specific PDF I want to load when a button is clicked. The PDF is 28 Megs big and takes some time to load into the reader. I would like a progress bar to to show (like a showdialog kind of thing) so the user does not click all over the place and thinks the app is static.
The PDF reader is loaded like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.AxAcroPDF1.LoadFile("c:Section3.pdf")
End Sub
How would I update the progressbar1 control to reflect the time it takes to load? I checked the AxAcroPDFLib Namespace and found no "progresschange" type of functions or events.
I have a multiline textbox which is loading from a .dat file. However, despite telling it to load all of the .dat file, it misses off the end. I it copies the first large body of text and a load of spaces that are inbetween the first and second body, but doesn't load the second body of text. Here is the code I'm using to open my file:
RichTextBox2.Text = IO.File.ReadAllText("00061530.dat")
Can you tell me what event takes place after a form is loaded and displayed including all controls on that form?

View 1 RepliesI have two rich text boxes, and two buttons on my screen. The first button grabs HTML from a URL and then converts the HTML to XML which resides in rich text box 1.
The second button is to grab the XML from the rich text box1 and then parse it to grab all the input elements by their ID.
My issue is that my parser isn't doing anything. My guess is that I'm not quite getting the XML from the first rich text box.
What would be the best way to grab the XML from a rich text box load it into memory and then parse the XML to grab all the ID tags?
Here is my code --
Imports mshtml
Imports System.Text
Imports System.Net

View 5 RepliesI'm have a quite big application which have 2 serial ports and access 1 DB (running on Background workers). I'm experiencing some random locks while the application is running and I started looking for something that could cause it. One of the obvious possibilities would be if I had in the GUI thread some While_End that would never return.I have one While_End in my GUI thread but IMHO it does not look like it would lock, so I want your opinion: Does the code below looks like will lock?? If 'yes', Why ?

Does anyone can imagine a scenario where this While_End would not return ?

View 4 RepliesOkay, so I'm doing a card game and I'm trying to set that when picturebox (PictureBox1) is clicked, a random card from 13 cards will come visible. Problem is, that when i start the program and click the picturebox, the same card will always come visible. As you can see i've put a button (Button1) which will hide every card. If I press Button2, then Button1 and then the PictureBox1 it will show differend card, but the cards which come visible are always the same.
e.g i press PictureBox1 (which will make card visible), then Button1 (which will make PictureBox1 non-enabled) and then Button2 (which will hide every card and make PictureBox1 pressable). Lets say i pressed the PictureBox1 four times and i got cards: 9, 6, 7, 3, then I close the program, start it again and press PictureBox1 again 4 times and it will show the same cards (9, 6, 7, 3). How can this be done that it will not show the same cards always?
Here's my code...
Public Class Form1
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
End

I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
View 9 RepliesThe class Random is out right defective. It always produces the same random numbers in the same sequence. Things I have tried so far is every kind of seed you can think of as well as Randomize. The result is that I always get the same random numbers in exactly the same sequence.
View 4 RepliesI am practicing using the drawing commands, and have gotten a grass background and black happy face that moves around the background.It's a 10x10 grid of 50 pixels.I want (at the moment, when i press enter) it to generate a random number of trees (15 ~ 25) at random locations on the background. The program doesn't freak out about anything, and the variables seem to be right (using stop commands) but it's not drawing anything. Here is the code for the "GenerateTrees" command I have for when I press enter.
Private Sub GenerateTrees()
NumberOfTrees = Int(Rnd() * 10) + 15
For i = 0 To NumberOfTrees - 1

-Random Integer (1 to 100)
-Random Answer (Yes or No, similar to a coin flip)
-Random Dice Roll (1 to 6)
How would I go about doing this?At the moment all I know about random numbers etc. is that I will need to do something along the lines of Dim dice As New Random or something like that, but, like I mentioned, I have no idea.I am well aware of the DIC rules that you won't write the code for me/do my "homework(?)" for me, and that's not what I'm asking.
VS2010 (SP1) / .NET 4 on Windows XP. The question is simple, the answer; not so much. When generating a salt, should the LENGTH of the salt be random, fixed or a random number within a (min/max) range? I am using RNGCryptoServiceProvider to generate the salt, just unsure of the length of the salt.
