Using An Array To Navigate Forms?
Feb 18, 2010
I'm starting to learn arrays, but I'm a little bit confused on how to call the data listed in them.I have the following code in a module and was wondering how I call them in my forms.I was told to use a counter to keep track of where the User is in the code in order from them to navigate correctly. I'll be using Next and Previous buttons.
Public FormList() As Form = {frmMain, frmStartup, frmUninstaller, frmAutomation}
Public CurrentForm As Integer = 0

Is it possible to navigate through an array just like you can with an ado.recordset, i.e. movenext/moveprevious/etc?To give you an idea of what I'm trying to achieve. I have a form with next and previous buttons on it and I want the user to be able to go to the next/previous record in the array.

I have code to create a listbox and populate it, and would like the box to behave like it does when clicked, e.g. if you CLICK on "a" you see it blue and can press the down arrow to move down to "b". how do I achieve this programmatically?
Private Sub junkloader()
brandlist.Visible = True
brandlist.Items.Clear()
brandlist.Items.Add("a")[code].....
this code SELECTS it properly, but I want to be able to navigate with the up and down arrows. how do I do this? thanks.

I'm guessing there is a really simple answer to this but i've spent the best part of 2 days trying to get it to work and cannot figure it out.Basically, I want is the webbrowser to point to a local folder on a machine. A different one depending on who is logged on. The code I have so far is as follows.
Imports System.IO
Public Class frmFav
Private Sub frmFav_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim username As String
[code]....
I cannot get the URL value of the webbrowser (FavProgs) to take the value of directoryname. If I set the URL value in the properties for FavProgs it does what I want it to do perfectly.

In my app I am using a web browser control, I am displaying a list of files that are there in selected Directory, when the file type is of some image I do it as WebBrowser1.Navigate(sFileName), the image is then displayed in the Web Browser Control, when there is Word Doc I had code that converts the word doc to HTML and it is displayed in the WB Control all good so far, now when the file is of type xls, xlsx I am not converting the file to HTML instead I just use the navigate command and open the file in Excel so that user can then edit it and save it on his system. Now the problem is lets say I am toggling through pages in Directory first file is Image so it will be displayed next when it is Excel file then it will open the file in MS Excel but the WebBrowser COntrol has that previously opened image, I want to clear that when the excel file is opened. So here is what I tried. [code]It navigates to Excel file but does not display text and the image from previous file persists in the web browser control.I even tried to navigate it to "about:blank" but it then does not navigate to Excel file.

We are using a web browser to show a pdf file located in a folder on the network. The code looks like this:
System.Windows.Forms.WebBrowser.Navigate(New Uri("\hostpath ofile.pdf"))
This works fine, but now I have to use a specific user to access this file and I don't know how to include the user name, password and domain in the URI. Is it posible to add user credentials to the URI? Can I use another variant of Navigate method to accomplish this?

I have a form with two web browsers. I have webbrowser1 navigate to a parent url and webrowser2 navigate to child url.
The page in webbrowser2 loads correctly but when I make a change to an element it doesn't also change the value in webbrowser1 as it should.
Should I be looking at cookies or something else?

I want to make something that can on button click navigate to a page, wait the time I specified and navigate to another page..
[CODE...]
This does not do what I thought it would do..I think that the problem is that when it sees System.Threading.Thread.Sleep(5000) everything stops for 5 secs .How can I make it go to google.com and then after 5 seconds, yahoo?

I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

Basically I want to find the first occurrence of one array in another. I have tried using the Array.IndexOf Function, but it always returns -1. Example:
Dim array1 As Byte() = {1, 2, 3, 4, 5}
Dim array2 As Byte() = {2, 3}
MsgBox(Array.IndexOf(array1, array2))
Even though array2 does exist in array1, the message box always shows -1

Alright, so I need a method that traverses all the forms inside a VB.net project under Visual Studio 2008, and create an array of type form with references to all the forms inside it, so that the array looks like this (pseudocode)
FormsArray() = [Form1, Form2, Form3, Form4]
However, I don't have a clue as to how to begin.

I am trying to populate an array from a listbox.My listbox items contain something like this:
1 for January
10 for February
3 for March
I have code in place and it was working, but I am taking the first character of the listbox item to populate the array. If the value of the listbox is 10 for February, I need to get 10, not just 1. Can I do something with the string that says I want to trim everything from the space to the end? Since they are all formatted the same way, if I could trim out anything from the space on, that would work.
Here's what I currently have:
ReDim m_adecRainfall(m_astrMonths.Length - 1)
For intCount = 0 To m_astrMonths.Length - 1
m_adecRainfall(intCount) = CDec(lstMontlyRainfall.Items(intStart).ToString.Su bstring(0, 1))
intStart += 1
Next

I have an array of items where i have separated the first two characters, which in my case are ID tags. I have populated my CLBox and the output is like this
AA
Aa
BB
[Code]...
What would the process be to do this, would i need to create a reference list or stringbuilder for all the tags(there is about 3000 tags) or would it be possible to loop through and count the matches. I declared the Tags thinking that i could do something from there.
