Get Rid Of ActiveX Warning In Application Using WebBrowser Control?

Jan 28, 2011

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?

MS WebBrowser ActiveX Control?

Apr 11, 2011

I am using the WebBrowser control in Rockwell Automation's Factory Talk SE v. 6.0 to display a PDF file. Within the "Display_AnimationStart" routine, I call the function below to send a ctrl+h to the system to hide the toolbars, which has proven to be quite unreliable.

Is there a more direct, object-specific way to hide the browser's toolbars other than the SendKeys method?

Private Sub LoadPDF(Filepath As String)
SendKeys "^h", True
Me.WebBrowser1.Navigate2 (Filepath)
End Sub

IDE :: Enabling ActiveX Controls In Webbrowser?

Jun 3, 2006

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.

Webbrowser Control On Form2 Vb Windows Application?

Dec 9, 2009

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

3) I marked the sub startup() with STAThread()

Internet Explorer Gives Script Error With WebBrowser Control In .NET Application

Mar 12, 2011

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.

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?

ActiveX Control Won't Start?

Apr 27, 2009

I created an ActiveX Control in ATL, which I can succesfully use in for instance Internet Explorer. When I want to put that object in a VB.NET (2003) app, I get some problems.

First I 'Import' the control, using Visual Studio, so there are COM Interop DLLs created. Then I insert the control in the toolbox and drag/drop on a form. The control is succesfully created.

However, when I run the VBApp, it crashes. The debugger tells me that it gets a 'Class Not Registered' error.

Same when I create a pushbutton and create the object manually:

Code:
Dim AxQuest3DCtrl As Object
AxQuest3DCtrl = CreateObject("MyControl.MyCtrl.1") //crashes here
If AxQuest3DCtrl Is Nothing Then

Can't Create ActiveX Control

Working on getting a legacy app up and running again for work. I'm getting an error at run time that I can't create an activeX control. The suspect call is

oSQL = CreateObject("SQLDMO.SQLServer2")

I did a bit of googling and found that SQLDMO should be in a SQLDMO.dll. I've got that DLL referenced in my project but it is still failing.

Migrate A VB6 ActiveX Control To .net?

Jul 9, 2009

I have a legacy VB6 ActiveX control used in IE to provide control of a parallel-port device from a browser application. I wrote this thing about five years ago; It's a pretty simple control, and it doesn't require a lot of maintenance. However, I've noticed that running the VB6 tools is becoming more and more painful over time, so I'm looking at the possibility of migrating this code to VB.net 2008.This thing is super-simple. It implements IObjectSafety and exposes a single public method, which we call using Javascript. The control has no UI other than a single box with a caption that displays its name and version number-- useful for troubleshooting deployment issues.

How would I create the equivalent in .net? Am I creating an applet? Or a .net Assembly? Any gotchas to look for as I try to make this transition?(I should make it clear here that I'm not either a VB6 programmer or a .net developer-- I've dabbled in this stuff but it isn't my area of expertise, so go easy on me).

ActiveX Control (.ocx) Behavior At Runtime?

Dec 31, 2009

I am developing an application in Visual Basic under Visual Studio 2008 Professional. As part of this application I am using a third-party ActiveX control (.ocx file). After building the installer (.msi file) using the deployment tools in Visual Studio, I tested it on a clean system. The install appeared to run successfully--folders are created, files are copied, and the .ocx is registered. However, when I tried to run the application I received an error telling me "You must have a license to use this ActiveX control." This would be expected on the development machine, but should not happen on the client system, i.e., in the runtime environment.

On previous builds of the application, I did not receive this error. Besides updates to the application itself (the part I created, that is), I was using NSIS to create the installer, rather than the tools in Visual Studio. The application cannot run without the .ocx in question, so this error is a show-stopper.

ActiveX Control - Trapping Tabs

Failed To Import ActiveX Control?

Jun 7, 2006

I am using VB2005 express and VC#2005 express. With my old friend VS2003, whenever i needed to add flash to my WInforms, all i needed to do was to add the control as a com component and drag it on the stage from the toolbar. Now, when i did the same in new express version, althogh it is added in the toolbars and the references list, but still, whenever i try to drag a shockwave flash instance on my win form, i get the error: Failed to import ActiveX control, please ensure it is properly registered.

does some one have any idea how to add flash comntrol as we used to do in earlier versions?

Using The Same ActiveX Control In Different Forms: 2010?

Aug 11, 2011

I am writing a customized data acquisition application in VB2010. The maker of the data acquisition hardware has provided an ActiveX control that has methods, properties, and events that can be used to interface with the hardware device.My problem is that I'd like to reference the same control (ideally the same instance of the control) on multiple forms.

To begin, it is necessary to initialize the device, sending the control information like sample rate, number of channels, etc. Then you can use methods to start or stop getting data and read properties, like the number of samples taken, or an array of the
actual data. The device also provides events, like a DataReady event that fires when a certain number of samples have been taken, and a DeviceError event that fires if the device is not present.

My program will have several forms:

1) a main menu that opens on startup and that should initialize the unit and determine whether it is present.

2) a daily check form that will get values from the device to determine whether the electronics are good.

3) a test setup form that will get values from the device to zero (tare) the input channels.

4) a run test form that will acquire and process the actual test data.

If I include separate instances of the control on each form, I need to initialize and stop the control when the forms open and close. I started to build an interface class that the forms could share and that would deal with all of the methods, but I get tripped up trying to pass the control's events back to the form.

ActiveX Control Using VB6 - Cab File And Html Page

Jul 25, 2011

I've developerd an ActiveX Control using VB6. I've also developed its installer .cab package for web. A simple html code is given below that explain how i use that package in html page

<HTML>

<HEAD>

<TITLE>MyAcrivexControl.CAB</TITLE>

[CODE]...

<!-- If any of the controls on this page require licensing, you must create a license package file. Run LPK_TOOL.EXE to create the required LPK file. LPK_TOOL.EXE can be found on the ActiveX SDK, [URL]. If you have the Visual Basic 6.0 CD, it can also be found in the ToolsLPK_TOOL directory.

The following is an example of the Object tag:

<OBJECT CLASSID="clsid:5220cb21-c88d-11cf-b347-00aa00a28331">

<PARAM NAME="LPKPath" VALUE="LPKfilename.LPK">

</OBJECT>

[CODE]...

In ideal situation whenever i run this page by typing url like [URL]. it should ask me for download and install the control, but it didn't.
