Setting trust level for windows.system.forms.browser control

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :WPF
 

Hi All,

I am using a browser control in my WPF application. The users of this application will be using this control for viewing content that could contain malicious scripts. I want to set the Trust Level so that none of the scripts should be executed. I have added the Attribute to the method that creates the Browser control. I dont think its working though. Any thoughts on how this can be done?

Is Dispatcher.BeginInvoke really NOT thread safe, while the old System.Windows.Forms.Control.BeginIn

  

Hello.

 

System.Windows.Forms.Control.BeginInvoke is documented as thread safe (in fact, BeginInvoke , EndInvoke , Invoke , InvokeRequired , and CreateGraphics are).

Great!

 

But in WPF, Dispatcher.BeginInvoke is not documented as thread safe. Which would appear to me as a regression (and not really convenient, to be honest).

Was it only forgotten in MSDN documentation, or should I really use external locking to prevent the dispatcher to get lost in its messages and priorities?

 

 

Thanks. ;)

Cutting Edge: A New Grid Control in Windows Forms

  

Grid controls are essential in many of today's apps. Until now, though, most developers using Visual Basic® have had to buy third-party components to get an effective, easy to use grid component. The Windows® Forms DataGrid turned out to lack too many features for the average developer.

Web-Aware Apps: Build Hyperlinks into Your Client App with the Windows Forms LinkLabel Control

  

LinkLabels are Windows Forms controls that enable a user to hyperlink to a URL that points to either the Web or the local directory system. While the SDK documentation discusses the control, it does not demonstrate how linking is accomplished, nor does it outline the power and flexibility the control provides. This article fills those gaps, showing how to link using the LinkLabel control. It also shows the flexibility of this control for the programmer using the .NET Framework. In addition, the author covers the large number of properties that allow you to customize your controls and accurately place them. Their built-in behaviors are also discussed, along with their use in both Visual Basic .NET and C#.

A first chance exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll

  
I've read a bit about this error and maybe I have nothing to worry about.  BUT ... my simple little app gets 7 of these before it even gets to the first Dim statement in the Class Form1!  I found and followed instructions on how to have the Debugger intercept these exceptions but it seems that they are not being intercepted.  I only know that they have happened because of the messages in the Immediate Window.  In the Designer all I have is 5 Labels and 5 TextBoxes.   Any thoughts on how I could get to the cause of these messages? Thanks,  Bob

System.Windows.Forms.InputLanguage.LayoutName

Converting a System.Windows.Control.Image object to byte array.

  
Hi i need to convert a specific System.Windows.Control.Image object into an (int) array, because i'm trying to convert a silverlight application into a wpf project. private void createGi02GradBrush()<br/> {<br/> WriteableBitmap oWriteableBitmap = new WriteableBitmap(256, 256);<br/> Image oImage = new Image();<br/> oImage.Arrange(new Rect(0, 0, 256, 256));<br/> oImage.Measure(new Size(256, 256));<br/> oImage.Source = new WriteableBitmap(256, 256);<br/> Gi02GradShaderEffect oGi02GradShaderEffect = new Gi02GradShaderEffect();<br/> oGi02GradShaderEffect.pArray = oPImageBrush;<br/> oGi02GradShaderEffect.gi1GradArray = oGi1GradImageBrush;<br/> oImage.Effect = oGi02GradShaderEffect;<br/> oWriteableBitmap.Render(oImage, null);//here<br/> oWriteableBitmap.Invalidate(); <br/> this.oGi02GradImageBrush = new ImageBrush();<br/> this.oGi02GradImageBrush.ImageSource = oWriteableBitmap;<br/> } I've found some similar topics however Image object is not the same and most of its methods aren't available. Here I'm rendering a writablebitmap with a given Image object, but in wpf we need an array. oWriteableBitmap.Render(oImage, null); Any idea? Thanks. Joseph.  

Problem with overriding OnPaint method of System.Windows.Forms.Textbox

  
Hi,   I want to change the border colour of the Textbox. However, when I override the OnPaint method, some strange behaviour occurs.   The new border is drawn, as is the textbox background. However, the text itself appears in bold and only while I actually type something in, afterwards it disappears. I have provided a sample of my code here:         protected override void OnPaint(PaintEventArgs e)         {             base.OnPaint(e);             Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);             ControlPaint.DrawBorder(e.Graphics, rect, _BorderColour, ButtonBorderStyle.Solid);         }   I have also set the style of the control to Userpaint, so that the paint method is actually used. Does anybody know how to solve this issue?

Add property to user control design time properties VB windows forms

System.Windows.Forms.WebBrowser strips out #fragments

  
I have a WebBrowser called webBrowser. I call: webBrowser.Navigate(@"file://C:\Documents and Settings\michaelb\Local Settings\Temp\tmp2F.tmp\OPS\main3.xml#section_5343"); I have a handler for the Navigating event: void   webBrowser_Navigating(object sender, WebBrowserNavigatingEventArgs e) Inside the handler I see that e.Url has no properties in which the fragment (i.e. the # onwards) has been retained - all knowledge of the fragment has vanished. I saw a posting in the WPF forum where a developer had noticed that the WPF browser control was doing this with a URL using the http:// scheme. The expert responding said that this was a known problem and that the workaround was to use the traditional WinForms browser control (i.e. the one I am using). I, however, am seeing that same problem with this WinForms browser control - the only difference that I am aware of between my case and that described in the other post is that my URL uses the file:// scheme. Anyone know a fix? Regards, Michael

Word Interop - System.InvalidOperationException in System.Windows.Forms.dll

  

Context:

Microsoft Visual Studio 2005 Version 8.0.50727.42 

Microsoft .NET Framework Version 2.0.50727

Word 2003 Interop


Problem:

I am trying to recreate the "AmbiguousMember" example from p. 31 of Whitechapel's "MS .NET Development for MS Office" using VB instead of VC#.

This involves implementing an event handler for the Word Quit event. In the event handler, I need to toggle the Enabled state of two buttons. This causes the following error:

A first chance exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

The code behind the Form1 form is shown below. Form1 has two buttons: Button1 "Run Word"; Button2 "Quit Word". The event handler is intended to clean up if the user quits the Word application, and reset the buttons.

Setting .net windows control location based on Screen width

  
I am developing an windows application in 20 inch moniter. I am positioning the controls in WPF like this

scrollViewer1.Height = Screen.PrimaryScreen.Bounds.Height / 5;

Please clarify?

If it will chnage the positioning,please suggest how to poistion the control to support all screens widths.
