I am working on an application with about 50 controls and want to arrange the events so that I can find them easier. There are several events for each control and since they wer all created at different times code for controls is in order by date created.
I want to change the order. Naturally I want to avoid cutting and pasting.
I'm relatively new to vb.net. I just created an simple Electronic Raffle web application via Visual Studio 2005. It's working just fine since it just basically returns a random winning entry queried from an SQL Server database. However, to make the raffle draw more "dramatic", I would like display random entries before actually displaying the winner. I tried creating a for-loop which displays random numbers before displaying the winning entry but only the end result (winning entry) is displayed.
I even tried to display an animated gif file then hide it again before displaying the winning entry but only the winning entry is displayed when I click on the "Draw Winning Entry" button.Is there a way to set the sequence of events in a web browser such that the program should display the image first then hide it after 5 seconds then display the winning entry afterwards?
In my program; I need to collect a sequence of events in a variable of some sort. Each time the Sub is initiated, it should add one random event to the sequence (so that it gets longer each time) and then run through the sequence.This is rather difficult to express.What I'm trying to do, is create a Simon Says game with the four buttons.After the sequence goes through blinking the buttons, the program must then be able to capture the sequence of button presses by the user and match that to the sequence that the program ran.So, I need to be able to keep track of two sequences in a variable. Arrays?

I have a program to add and remove sites from the HOST file. So, sorta like a site blocker. I kinda wish I had a chicken in a police outfit giving the stop! hand sign and name it cock blocker :P anyways... To read what sites/ip's are blocked I'm just reading the HOST file in a read only textbox. I was wanting to know if I can read everything but the crud at the top of the file(Describing how to edit the HOST file manually). How could I do that? Here is my code I'm using to read the HOST file:
Dim ReadItem As String = String.Empty
IO.File.Exists("c:windowssystem32driversetchosts")
ReadItem = IO.File.ReadAllText("c:windowssystem32driversetchosts")

View 3 RepliesBeen working on a Web Browser in VB 2008 Express, and so far things have been going good. I have run into a little problem though. I have a menu bar at the top of the browser as normal and one of the items selects is "View" and then under that "Page Source".
Now, i have added the following code and it works as expected but one problem. When the box opens to display the web page source it has no scroll bars, minimize or maximize buttons to manipulate the page.
Private Sub PageSourceToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PageSourceToolStripMenuItem.Click
Dim pagelSource As String = WebBrowser1.DocumentText
MsgBox(Me.WebBrowser1.DocumentText)
End Sub
I think the problem is that I am using "MsgBox" . Would there be a better way to do this?
I used visual basic 2008 express edition and I read the "How Do I" tutorial and I went over with it but there are still some instances I can't find or figure out and I need some assistance. I used the LinqtoSQL classes in my project, I have one database and has one table in it,now here is the output of my project.Everytime I first run my project I would be able to view all the records in the table that is inserted in the datagridview on one of my form w/c has existing records that Ive added when I input records when running but when you add new records into it and after adding the new records when you view it right away it would only display the records in 4 fields or 4column of my table and I have 8 fields or 8 columns in my table the rest are blanks but when you exit the program and run it again that's the time you can be able to view all the records in the datagridview attached on a form.I want that when I add records and view it would display all the records w/out needing to exit the program.

I am trying to make a program that can open pictures in its own PictureBox. I have the form already made, and I had it working with a combobox with the list of all the different pictures, a button to load the picture depending on the selected item in the
combobox (MANY MANY if statements), and i also added a previous and next image pair of buttons (200% more if statements). I was happy with it, except whenever I added a new picture I had to add many lines of code... So i figured i can use this openfiledialog
and open them that way.
what i have so far is when i press "btnLoad" it opens the "ofdPictures" {openfiledialog}
what i need it to do is when i select my picture and press "open", it open the image in the picture box "picPictures", which is in my form.from what i understand with playing around with openfiledialog in VB is that the command this->ofdPictures->FileName
makes the selected file a string... but i think i have to make it = a string variable...
now, i think i fixed that by adding to "private: System::Void ofdPictures_FileOk"
