View 2 RepliesMake Assembly FULLY Trusted - Use The Web Browser Control In User Control
Dec 19, 2009I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!

View 4 RepliesHow To Make Transparent User Control
Oct 17, 2011I did some research on how to make transparent User Control, The suggested code was like this:
Private Sub New()
' This call is required by the Windows Form Designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
Me.SetStyle(ControlStyles.SupportsTransparentBackColor, True)
Me.BackColor = Color.Transparent
UpdateStyles()
End Sub
When I build the project, there is no errors. But, When I try to load my user control using the "Choose ToolBox Items" dialog, it gives me the following error message:
"There is no components in [dll path] that can be placed on the toolbox."

Make ControlLibrary User Control Hide()
Oct 6, 2011I've spent three days trying to get a user control to do some obvious things -- show, hide, and focus among other things. Done in vBASIC in Visual Studio 2010 Pro. The calling program is a Windows Forms Application, while the user control is a WPF Custom Control Library with a single object, a textbox. The reason it's a user control is that this textbox is connected to an async serial device; the reason it's in a Custom Control Library is that I'd like to be able to drop this functioning serial-port-connected textbox into future projects.
No matter what syntax I attempt, the user control (neither the control nor the text box inside it) will Hide(). I've tried every variation I can think of with control.Visible = false, exposing public subs to do the work, etc. When the form appears and characters are typed in the field, the KeyPress routine is functioning -- it will only accept numeric digits.
Here's the vastly reduced code to illustrate the problem:
Calling Windows Forms Application
Imports DTRFormsControlLibrary2
Public Class Form1
[Code]...
In spite of the call to sbControl.Hide(), the form opens with a very visible and enabled user control text box. The ability to control visibility, focus, and enable/disable seems fundamental to any control.

VB 2010 - How To Make User Control Transparent
Mar 19, 2012I have code for make the usercontrol transparent:
Protected Overrides ReadOnly Property CreateParams() As CreateParams
Get
Dim cp As CreateParams = MyBase.CreateParams
cp.ExStyle = cp.ExStyle Or &H20
'WS_EX_TRANSPARENT
[Code] ......
These code shows the usercontrol transparent. But when the control moves I see that these control needs time to be transparent or drawing an image. Why so many time(maybe 2 seconds)? And why I can't use directions keys on keydown event? (The arrow keys are ignored).

Access User Control Attributes From A User Control?
Mar 27, 2009I am trying to build a tournament bracket application. In order to build the application efficiently I would like to make a user control "GameControl" that represents a game and give it attributes that represent the names of the competitors "TeamNameA" and "TeamNameB" ,an attribute "Winner" to represent which team should move on, and an attribute "NextRoundGame" that assigns another instance of the user control so that it can assign the "winner" to one of the "TeamName" attributes of the next round in the competition. If the controls were native to VB I feel like I could do it easily (I have only spent about 30 hours self teaching/tutorial following) but I can't seem to find out how to pass values to custom attributes of custom user controls through code.
