WebBrowser Control Make Application Or The Deployment PC Vulnerable To Any Significant Security Risks?
Mar 17, 2010
I have a Visual Basic.Net Windows Forms application to which I am considering adding the WebBrowser control. I'm assuming that the PC's on which this application will ultimately be deployed/installed will have the latest Windows (XP, Vista, or 7) updates, a firewall, and an Internet security suite installed/running.
With this deployment environment in mind, does the WebBrowser control make my application or the deployment PC vulnerable to any significant security risks? Are there any programming issues that should be addressed to eliminate potential security risks when using the WebBrowser control?
How do you disable the Security Alert?I'm using the WebBrowser Control to open office documents and everytime I navigate to the files location and when use the right mouse button or try to open a document
I get a Security Alert Form that ask, You should only run files that come from websites that you trust.
I am attempting to write a VB.net application which will allow users to create their own widget plugins in html/jscript and i would like to set my own security options in the applications settings allowing users to choose what can run or not eg scripts, flash, activex.I would like to allow activex controls to be used without the windows security dialog in the WebBrowser Control (An ActiveX control is trying to interact with the page...) or what ever it says.
I started customizing the WB Control to suite my needs implementing various interfaces such as IOleClientSite, IDocHostShowUI, IDocHostUIHandler, etc...I can't seem to find anything that will allow me to control the security permissions of the WB Control. I tried to implement IHttpSecurity and IInternetSecurityManager but I'm either barking up the wrong tree or not doing it right.
I have made an simple application (.exe). When i run this program local on my machine it works fine. When i run it from an server i get the system.security.securityexception message.
I have now spent a long time trying to figure out how to fix this problem, hoping someone here could give me some hints What I'm trying to do: I need a way to save mail items to a folder on the computer What I have done so far: I created a component, where you could drag a mail item from Outlook on to. This component then saves this mail item to a folder on the computer

is there a way in vb.net to make it so that if the html in a web browser control contains a certain word then on startup it will show a dialog box. Basically I want to create an update system in which when the update dialog box web browser control html contains the words "update available" then on start up the dialog box will show prompting the user to update.
I need to make a very simple browser. The problem is that it has to be a WPF application because I'm using a SDK that does not support windows form applications. My question: is this possible and how? Is there some xaml to achieve this?
I am using a VB.NET program that uses the WebBrowser control to navigate the Web. The site that I need to navigate to suddenly became not IE-friendly. So, I am thinking to try to make it look to the site that the WebBrowser control is not IE, but a Mozilla Firefox browser.[code]...
We have a VB.Net app that has several editable reports and forms in html/javascript. I'm using the standard WebBrowser control.We're accessing the content via filepath, since using localhostsharename when the machine is offline doesn't work even though the content is on the machine. The problem with that is that then it's running in the local machine zone, and you get the warning about running ActiveX controls (even if that's set to 'allow' in the options menu on IE). So I'm using Mark of the Web to act as if the content is saved from localhost. I appended it with the requisite vbCrLf to the start of the HTML page that's being dynamically written every time a link is clicked. When I open the resulting page in IE, I no longer get the ActiveX warning, and everything works. However, when I use WebBrowser.Navigate to that filepath, I still get the warning. Any idea how to get rid of that?
I currently have a simple VB.Net WebBrowser program uses webbrowser control, I 'd like to have certain data returned by a sever in the open web page send to the VB.net program, i.e. retrieve the html response from ASP.NET page.
i need to query a database a user's Full Name, when data is returned by the sever side script, it won't do any update on the web page, instead it should notify the VB.net program what users' full name is.
I have a vb windows application with 2 forms, where form2 is called from form1 using form2.showdialog()
I added a web browser control to form2, and I'm getting the following error at the point where form2 is called:
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.
I tried: 1) adding STAThread() to the form_load()
2) I added a module to my application, and created a sub main(), with the STAThread attribute applied to it
im trying to make my program click an link on the webbrowser control. The link changes everytime.Basically its an email and when opened in webbrowser its a google account versidication email.

I made a simple application for a website, the site has a IRC-chat and the program should let you close the window (or actually minimize it to the system tray), and then open it from the tray.the problem that occurs, is that I keep getting a Script Error from IE:url...the weird part is that this does not happen when using Internet Explorer on it's own.so it only happens within the WebBrowser Control in the application I made.the application, also, couldn't be more simple, it had just a single window with only a webbrowser control that loads url..., further the program only has a Notification Icon and a Contextual MenuStrip for the Notification Icon.
I am writing a windows form application, where I want to have a WebBrowser control, and in that control, I want to show a Google map programmatically generated (I mean, not just specify a URL to the browser).
I have a Windows XP box that is showing vulnerable by a 3rd party scanner for MS08-070 in regards to four OCX files tied somehow to Visual Basic 6.0. However VB6 is not installed on this computer; attempts to download MS08-070 and patch doesn't work.I'm guessing there is a some other application that may have dropped these in my c:windowssystem32 folder. The file versions are older as compared to what MS08-070 say they should be so I'd like to get them patched/updated.Microsoft's recommendation in the article is to update the application on a machine that has the latest patches for VB6 and redistribute that application.
How can I make my program to work only for certain period of time?Say... I want my program available for only One hour or Two days or one month or etc...
Question:Using VB.NET/C#, is it really not possible to read the below XML in a dataset without significant work ? I tried
oDataSet.ReadXml(strFileName)<BR>and Dim oDataSet As System.Data.DataSet = New System.Data.DataSet Dim strLocation As String = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) strLocation += System.IO.Path.DirectorySeparatorChar + "filename.xml" oDataSet.ReadXml(strLocation)
But all this is doing is putting ONE row with one cell with content "2010-02-12T10:33:39" in my dataset.
I want to use PKI public and private encryption for authentication to allow for a more streamlined and secure application access control system. Any help in the generation of certificate and authentication will be useful. One more question, can i use System.Security.Cryptography.X509Certificates class for the same?
i want to make an application that i can control the volume just like the volume icon on the taskbar. i did search and only find way to call volume setting using Call Shell("C:WINDOWSSystem32sndvol32.exe", 1)
this is not what i want. i want to call just one volume control trackbar only like the one on the taskbar.
I have another question though...I have searched all over the internet for this. And I have tried to create it. I want to know how I can make a window that will show all of the links posted on the site currently being visited, and show the cookies in the site.
Is there a number format in .Net that will display a given number of significant digits, but also NEVER displays in scientific notation (for example,declaring 3 sigfigs you would have 1234.567 = 1230 and .000123456 = .000123)

I'm working a project I can't discuss on here, but could someone tell me if it's possible to make a webBrowser control to have its contents wrapped like you can wrap the text in a textBox control?
For the past couple of days I have been using Visual basic 2008 and learning it.Anyway, I am trying to make a login form that will login to a website with WebBrowser control.and I am noticing that the webbrowser is extremly slow, it takes him about 20 seconds to load a page while mozilla opens it in a moment, why is that?
