View 3 RepliesI 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 setup a subroutine in Visual Basic .NET to go through an array of records and remove all records where the date field is before the current date.Here is my current code:
Sub FutureDate()
Dim movefrom As Integer
For x As Integer = 0 To UBound(notifications)
[code]....
After this sub is called, the program shows the first three records in the array in message boxes (for debugging purposes).However, when I run the program, the message boxes are never displayed. This sub is definitely the problem, as commenting out the line that calls it fixes the problem, and the appropriate messages appear, albeit with the first box containing a date in the past. This is for a notifications/upcoming meetings system, so I obviously don't want to include dates that have passed.The records are already sorted by date, so to my eyes this should do what I want it to, which is remove the records with dates in the past, move everything else to the front of the array, and then remove the spaces at the end that the records were moved from.
Is an ArrayList the same thing as a Structure (i.e. 'array of records')? If they're not the same think, what't the difference?

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:

IO.File.Exists("c:windowssystem32driversetchosts")
ReadItem = IO.File.ReadAllText("c:windowssystem32driversetchosts")

Been 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 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"
