I am using the following code to open up a pdf
WebBrowser1.Navigate("file://C:\test.pdf")
However instead of opening up in the browser it just keeps on launching adobe acrobat reader and opening the PDF in that, leaving the webbrowser1 untouched.
This is not what I want; I want my PDF to open up in my web browser
What am I possibly doing wrong?
I just solved this. What you need to do is drag your pdf document to your solution explorer and then open it from there.
Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("c:\users\Fake.Name\documents\visual studio 2010\Projects\SO\SO\test.pdf")
End Sub
I am working on solution 'SO', so I put the pdf into the solution and dragged the pdf to my code where it generated its location.
Also, take a look at this
Hope this helps
The problem with your code is the "file" statment.
Try this
WebBrowser1.Navigate("C:\test.pdf")
And you'll see the file opened into your webbrowser control.
In project properties check "Prefer 32-bit". Of course, that might bring on other problems (as in my case), so it's not a perfect solution.

I have a button in visual basic. I would like, when I hit the button for it to open up the TCP/IPv4 dialog window of the active network connection on the machine so that I can quickly and easily change ip address settings.
I can't seem to find a way to google this properly. All ways I can think to ask the question return unrelated results.
How do I open this dialog window with VB code?
Private Sub Button27_Click(sender As Object, e As EventArgs) Handles Button27.Click
End Sub
I'm not too sure if you can get it to open up straight at the WiFi properties of the current connection, but you can get it to open the Network Connections which should be able to save you some time.
Private Sub Button27_Click(sender As Object, e As EventArgs) Handles Button27.Click
Process.Start("ncpa.cpl")
End Sub
You cant open it directly but this article has a method using #Werdna's approach of using ncpa.cpl and send keys.
It also has the command line utilities for extracting / setting the ip.

Just wonder if you could help.
Basically I have a little project to finish, I have created a web browser with VB.NET, when I navigate let's say Google.com, I click to open a link on Google's website and it opens in a new page which is fine but the TextBox on my project (where the URL goes) does not appear any URL to which page/website I've gone to.
Can someone help me on this please?
Thank you so much!

You can do this by adding a handle to the Navigated event of the WebBrowser.
Private Sub WebBrowser1_Navigated(sender As System.Object, e As System.Windows.Forms.WebBrowserNavigatedEventArgs) Handles WebBrowser1.Navigated
Me.TextBox1.Text = Me.WebBrowser1.Url.ToString()
End Sub
The WebBrowser.Navigated Event is raised when the control has navigated to a new document and has begun loading it.
I have seen tutorials on how to open pdf files into the windows form, but they show how to open it by creating a button that will find it from the directory.
I want the pdf file to be displayed already, as soon as the user loads that Window form.
I have installed the Adobe pdf reader in the component toolbox, and
put the following code with the load function of the form:
Public Class Adding_Worksheet
Private Sub Adding_Worksheet_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
Call AxAcroPDF1.LoadFile(0, "D:\Mixed_Addition_1.pdf")
End Sub
End Class
I have adapted this from when I added an swf file, which had no problems in loading. I know the zero is incorrect above, but i am not sure what to write there. the additional code i had for the swf file was AxShockwaveFlash1.Play(). would i need to do something like AxAcroPDF1.Load()?
If all you want to do is display a PDF and nothing else, why not use a System.Windows.Forms.WebBrowser control, and make the URL "D:\Mixed_Addition_1.pdf" ?
Maybe he didn't want to use a web browser to open a PDF file, Right click item in toolbox, when designer is active, select choose items, select COM components and select Adobe. then add code to new form. Printer will be active, you can disable "Toolbar" in properties tab
Imports AxAcroPDFLib
Imports AcroPDFLib
Public Class TripSheet
'
'AxAcroPDF1
'
Public Sub New()
' This call is required by the designer.
InitializeComponent()
AxAcroPDF1.Location.Equals(AxAcroPDF1.LoadFile("C:\path\file.pdf"))
AxAcroPDF1.LoadFile("C:\path\file.pdf")
' Add any initialization after the InitializeComponent() call.
End Sub
I'm trying to follow a tutorial but I keep getting the warning:
Name 'AdobeReader' is not declared
Can sombody tell me what is wrong? The tutorial is found here, and I'm trying out Answer 2 from that page, which says:
Here is another way to read pdfs.
Right click on any of the tabs in your toolbox and click choose
items.(Just make sure you have a version of adobe reader installed
before starting.) When the dialog box pops up click the 'com
components' tab then pick tha 'adobe pdf reader' com component. Click
ok and you should now see a 'adobe pdf reader' control in your
toolbox. Click this and drag it to your vb form.(you may need to
resize it, usually appears very small). Now in order to read any pdf
just alter the 'src' property of the control either in code or in the
designer. when you run the program you should be able to view the pdf
doc in the vb form with most of the options you get in adobe reader.
Here is how you would alter the 'src' property in code.
PrivateSub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) HandlesMyBase.Load
AdobeReader.src = "C:\mydoc.pdf"
End Sub
If I´m getting your Question right, you just want to open a PDF-File.
Simply call:
Process.Start("Path/To/MyPdfFile.pdf")
In our application, when you go to "Menu > Help...", it opens our help files in Internet Explorer, which is the desirable effect. However, we have the shortcut key "F1" set to open the help files as well. It still opens the help in Internet Explorer... but it also opens them up at the same time in the user's default web browser!
Here is the code in the event method that opens the web browser:
Private Sub menuHelpHelp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles menuHelpHelp.Click
Dim temp As String = String.Format("{0}\Internet Explorer\iexplore.exe", Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles))
Dim temp2 As String = String.Format("{0}", Globals.HelpFilePath)
If Not System.IO.File.Exists(temp2)
MessageBox.Show(String.Format("Could not find index.html, run ""help_zip.exe"" inside the Doc folder as an Administrator to restore the help system (make sure to overwrite all files when asked!)"))
Else
System.Diagnostics.Process.Start(temp, temp2)
End If
End Sub
If I step through the code after clicking the Help menu item, IE opens as intended when I hit the "System.Diagnostics.Process.Start(temp, temp2)" line. However, when I do the same thing after pressing F1, it opens first in the user's default browser, and then in IE second. Any ideas? The code in this part of the application is written in VB.NET, and the application is a .NET 3.5 app.
Out of curiosity, have you tried binding the action to another button to see if the problem still exists? Switch it from F1 to F2, see if it still happens. Almost certainly will, unless there's some code in your program which you forgot about that's causing problems.
EDIT
You appear to be setting a global variable for your help path.. which means the default F1 Help would likely load the correct file. So I'd go with the "F1 is still bound to the default Help action." You'll need to unbind it.
