Open Pdf Files Using Either The AxAcroPDF Or WebBrowser Controls?
Jan 24, 2012
I'm working on an application to open pdf files using either the AxAcroPDF or WebBrowser controls.Preferably I'd like to end up using the WebBrowser control, however, I'm having the same errors using either and I need help in resolving this.The following error only occurs at runtime - not in debug mode:
"The instruction at "0x0546622z" referenced memory at "0x00000014". The memory could not be "read".Click on OK to terminate the program.The error only appears if the form containing the AxAcroPDF control is opened.However, if I run the program and not open the form then click on the button to exit the application, the application exits without errors. I've tried calling AxAcroPDF.dispose() both on the button.click event and the form.closing event

Private Sub LinkClicked(ByVal sender As Object, ByVal e As EventArgs)
Dim link As HtmlElement = WebBrowser1.Document.ActiveElement
Dim url As String = link.GetAttribute("href")
[code]...
Okay so here's the question how do I get the links that open in a new window to open in my main webbrowser control. The above code does some, but it's not fool proof.

I have a form with an Adobe PDF reader control.I point to a specific PDF I want to load when a button is clicked. The PDF is 28 Megs big and takes some time to load into the reader.I would like a progress bar to to show (like a showdialog kind of thing) so the user does not click all over the place and thinks the app is static.I have searched and read all about the progressbar and there are many articles dealing with downloading and moving files around but nothing in terms of file loading and how to get a progressbar to reflect the status of the file being loaded.[code]
How would I update the progressbar1 control to reflect the time it takes to load? I checked the AxAcroPDFLib Namespace and found no "progresschange" type of functions or events.Can some one please help a new guy out? I am fairly new to vb.net so please be as specific as possible.

Private m_LastPoint As Point = Nothing
' Start drawing.
[Code]....
Is it possible to draw directly onto the AxAcroPDF Control?
The AxAcroPDF Control dosnt have the mouseup and mouse down declatations so i am unable to easily adapt the code.

I have a small application (in VB.NET 2008) which gives the user the option to open a PDF document. This document is stored on a mapped network drive and is loaded in to the AxAcroPDF Control.
When closing my application I get the following message
The instruction at "0x0700609c" referenced memory at "0x00000014". The memory could not be read.
I've been google-ing this error message, but seen only a lot of problems, but no solutions.
I also tried using the WebBrowser Control, but this gives the same error.

I've created some messy code to look at the Readystate of each WebBrowser control and using boolean variable to track which WebBrowser control is done what. The time it takes to load 1000 URL's with one WebBrowser control is about 10 minutes. Multiple controls are needed for speed.
Here's the pseudocode of what I want to do:
Read a line from a file
Which WebBrowser is currently available to do work
Navigate to URL
Which WebBrowser is done loading a URL

I am creating a dedicated browser to be used exclusively on a single program located on my hard drive. Security is not a concern as the webbrowser URL will be set to the program's default web page path with no navigation options for going online. The program utilizes dynamic web pages with powerful search capabilities that require ActiveX controls. When I run my browser application, I get a series of security warning boxes stating:
Internet Explorer
An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction?
Yes No
Clicking "Yes" allows me to continue and the program features work, but the recurrent warning message boxes are annoying. The default "script errors suppressed" property of the webbrowser control is "false." If I change it to "true" I don't get the security warning boxes but some of the search features on the web pages with ActiveX controls don't work properly.
Is there a way to programmatically enable ActiveX controls in the webbrowser control so that I can set the "script errors suppressed" property to "true" (hence no security warning message boxes) and still allow the ActiveX features to work properly? Or, set the "script errors suppressed" property to "false" and have my program automatically activate the "Yes" button each time a security warning message box is called by Internet Explorer? The goal is to get the ActiveX controls to work in webbrowser without having to click through the warnings.

I have an VB.NET application that you can feed in using a file or other means a bunch of Website URL's and using six Web Browser Controls launched on separate threads navigate to and then images are captured. Almost instantly the Working Set Size accelerates to 1GB and continually rises as the process progresses until it flat out exhausts memory, of course it's a memory leak.
While watching the Performance monitor CLR managed memory is reasonably low and is being managed properly "cleaned up" as you would expect - Gen0,1,2 are reasonably empty. BUT non managed NET storage is out of control. So my question is: Web Browser controls are NET ActiveX objects... is storage ever allocated for them outside of CLR? And since they are really components of IE does their usage somehow require IE to generate and allocate storage outside of CLR. That is to say using a Web Browser control is just an API for the real the IE full browser and that does allocate storage in a non CLR managed address space.

I have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.
Unfortnately, I cannot get it to work for more than one file.
System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened
System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.

First off I'm using the Extended Webbrowser control from: [URL]
I use the Webbrowser control to access an ESRI web based mapping solution. When the ESRI map is loaded into an IE browser and the browser is resized then the map control resizing accordingly. When my Webbrowser control is resized the map webpage is not resizing properly.
I don't even know where to start with this problem. Is there some event that's not firing in the website? I can't simply refresh the whole website because the user may have panned and zoomed around. I want to just tell the website that the container control (Webbrowser control) is resizing now.

I have a program that autologs itself into facebook and monitors posts to my main page and tells me if anything new comes up. Every minute my program refreshes the page and searches for a new post, if my session is expired it logs itselft back in automatically. If I'm in explorer trying to play farmville and my facebook monitor program is running then I'm forced to log in about every minute because my login at the browser kills my vb.net program session.
Then my vb.net program logs itself back in and I'm out! This behavior doesn't happen If I have two browsers running I can log into both and it doesn't seem to effect the other. I can even have my wife log in from another machine while I'm logged in and It's ok. So The question is why is useing the webbrowser controls in the Vb program any different then just having 2 open and logged in browsers and jumping between the two.

Does anyone know if it is possible to open a firefox webbrowser in a form.Or does it take you default web browser as the webbrowser to open in form.
Eg - My Default Browser is Firefox - so does that mean the webbrowser control would be a firefox based one.
