I'm trying to play around with combo boxes and trying to figure out how to navigate to a certain url in webbrowser1 depending on the text selected in combobox1.
VB
Imports System.Windows.Forms
Imports System.Net
Imports System.IO
[Code].....
I have the following code that has the webbrowser1.navige via textbox1.text lines of urls:
Public Class Form1
Dim index As Integer = 0
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim lines() As String = TextBox1.Lines
If index < lines.Count Then
WebBrowser1.Navigate(lines(index))
[Code]...
How do I get the webbrowser to loop back around to line 1 (the url at the top) when it has finished navigating to the last line of text/url?
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'm useing WebBrowser1 and the code i use to get the text is[code]...
i want to make richtextbox that retrieve the selected text without the copy paste method.i want it to be sensitive to the mouse click so it can retrieve the selected text.
In my datagridview, I want to be able to change the value of comboBox1 depending on what the user selects in comboBox2
I had this working correctly, however if I move onto a new line in my gridview and select a different value in the second row it changes the previous row also. For instance, on Row1, if comboBox1 = A, combox2 = B
Then on Row2, if comBox1 = Y, comboBox2 = Z
However, when I change Row1, Row2 is also changed to reflect what was chosen in Row1. Is there a way I can tailor it to each specific row?
I am trying to add a welcome page to my app that loads from a web page.The problem is that it is freezing the entire app when I call navigate until the page is loaded. this is not acceptable.So instead I made it call navigate as part of a background worker process but still the app hangs and waits for the page to load.How can I force the webbrowser control to load asynchronously in the background so my application will function normally?I'm using VS2005, on XP SP3, IE 6.0
View 6 RepliesOk i want the browser to so something like this:
VB Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) WebBrowser1.Document.GetElementById("Login").SetAttribute("Value",TextBox1.Text) WebBrowser1.Document.GetElementById("pass").SetAttribute("Value",TextBox2.Text) WebBrowser1.Document.GetElementById("login).InvokeMember("click") 'now the problem is that the following statments finishes up before the preceding statment

I am trying to navigate to a website with json data using the webbrowser controls but it keeps prompting me to download the file instead of properly navigating to the page as firefox would.I have tried doing a regular navigate:
frmBrowser.WebBrowser1.Navigate("http://us.wowarmory.com/auctionhouse/money.json")
As well as editing the header content type with many different types:
frmBrowser.WebBrowser1.Navigate("http://us.wowarmory.com/auctionhouse/money.json", "", Nothing, "Content-Type: text/plain" & vbCrLf)
But cant seem to get it working.. I need to use the webbrowser to navigate as you have to be logged in to access this file.
Edit: Also, manually editing my computers registry won't work as I need to distribute this program.
Edit2: Just wanted to add that this code would work if it were the same session, but since it webclient creates a new session it doesn't work
Dim oWeb As New System.Net.WebClient()
oWeb.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
Dim bytArguments As Byte() = System.Text.Encoding.ASCII.GetBytes(params)[code].....
WebBrowser1.Navigate("http://" + TextBox2.Text + "/robbery/index/humanhunt/1")
How can i make this code execute the times that TextBox1.Text indicated?It should be some kind of loop. but i want it to repeat this every 100 milliseconds?
I want to learn how to populate a combobox so if a vlaue is selected in another combobox then it will be invisible for selection. You can NOT use combobox1.items.remove since my box is bound to a datasource.So I either need to create a new query and adapter and bind the combobox2 to that query, or fill combobox2 from combobox1 minus the selected item in combobox1. Either way I need some help writing code correctly.I have tried a few different ways but not succesful, I was probably on the right track a few times but I am still not very proficent in code writing.This is the code I have written so far for my program, I deleted all my attempts at remove selected item since none worked and were just confusing.
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click

OpenFileDialog1.ShowDialog()

i have form1 with combobox1 and rtb1 i would like to search the rtb1 for combobox1 selected value and return the first 9 characters from the line with the result.
COMBOBOX1
ADRIATIC
AMERICA
APAC-ANZ
[code]....
so if combobox1 selected.value = "BALTIC" then i would like "1209-4756" to become a named string (eg, cda = 1209-4756)
I am having trouble adding label.text, datetimepicker.text and ComboBox1.Text into listview1 box.I have set up multiple columns, one for the label, one for the date and one for the combo box text. All i have done is:
ListView1.Items.Add(DateTimePicker1.Text)ListView1.Items.Add(TextBox1.Text)ListView1.Items.Add(ComboBox1.Text)
How do i add these in the different columns so that they are all in one single row.
What is the appropriate declaration such as "ValueChanged" or "Click" for a NumericUpDown that will execute the code when I press enter. I already know that setting the "AcceptButton" property of the main form to a default button will not work, especially if I want a different button to be selected depending on which control I give focus. How do I accomplish this?
PS: Is the syntax any different from Visual Basic 2010 Express than it is on Visual Studio 2012 RC (running in Visual Basic Mode)?
[code]It just doesn't work.it errors. What it needs to do is navigate the webbrowser on the selected tab. Hwo to fix this?
View 2 RepliesI have a web page where I am trying to populate the PSI # into the txtPSI depending on which customer is selected in ddlCustomers. I have written it a way it has worked on a past project and it compiles with no errors, however it doesn't work when it runs.

Is there any examples with a treeview like this [URL] /scree...tinel-smod.png is it a case of having to draw each form how you would like to then hide/show the controls depending on what is selected in tree view????
View 14 RepliesI seem to be having issues with the selected index on a list box.
The list box is having various items inserted depending on the user selection. An example would be:
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "Item1")
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "AND")
[CODE]......................
This all work and displays without a problem. The issue I have is if I select the second of the two AND's. If I click the second "AND" in the list and then a button to fire a method, the selected index is always the index of the first "AND". Dim listIndex as integer = ListBox1.SelectedIndex
I can't work out why, the listbox itself will always show the second one as selected, but the action will happen against the first one.
I want to choose a value dynamically from comboBox depending of the values selected previously in two comboBoxes.the code that loads the comboBoxes:
Private Sub LightClassComboBox_DropDown(ByVal sender As Object, ByVal e As System.EventArgs) Handles AreaClasificationComboBox.DropDown
TrafficDensityComboBox.DropDown,.....
[code]....
The problem is that in the last Sub in the If sentence gives an error of: Null Reference Exception, because the compiler thinks that in that event the data are not loaded, although the data are loaded when loadcomboBoxes sub is executed.
When .Clear() is invoked, is the memory freed up that was allocated when all of the items were added? I need to load several lists of codes from a database depending on the import selected by the user. Each list of codes will be a List(Of String). My idea is that I will load only small strings into a List(Of String) along with a List(Of <class>) for the data I will be validating and manipulating. When I am done, I want all of the data from the Lists to be purged from memory. Will .Clear() take care of that or does the memory still remain allocated and have to be dumped by the OS once memory gets full? (And, incidentally, what causes the OS to decide which memory blocks to dump? FIFO concept?)
There are so many lists, I'm not sure if I just want them sitting in memory or not. Granted, the lists will just consist of a single string value for each code pulled from the database. So there won't be a ton of data, so maybe I could just load all the validation lists at the beginning of runtime and only worry about purging the data List since it will contain between 35-50 "fields" per record and there will be a couple thousand records each import that is run. I don't want my program to actually cause a hit in performance in the long run. I ultimately don't see a problem because I won't be running millions or even hundreds of thousands of records at once, but I just want to be sure.
