I want to create a custom user control to be used in a web page (by
object tag) as an assembly. The user control needs to have a web
browser control in it. Having tried with the managed
System.Windows. Forms.WebBrowse r or AxSHDocVw.AxWeb Browser, none of them
worked from IE invocation unfortunately. While
System.Windows. Forms.WebBrowse r showed the page in Visual Studio 5000
Designer, AxSHDocVw.AxWeb Browser caught an exception at Navigate
function call.
Anyway, now I'm trying to use Shell.Explorer. 2 in my custom user
control at runtime. The way I instantiate it is such:
Type loT = Type.GetTypeFro mProgID("Shell. Explorer.2");
this.IE = Activator.Creat eInstance(loT);
Then, this.IE can access all the properties of the ActiveX control,
like MenuBar, ToolBar etc.
However, it failed at, again, calling Navigate method. Debugger won't
step over the call.
If I replace Shell.Explorer. 2 with InternetExplore r.Application, it
worked fine. Except that's not what I wanted because it launches IE in
a separate window.
Interestingly enough, if I embed Shell.Explorer. 2 with its classid
directly into my web html page. It showed well, except the html object
id lost the reference to the control after exiting the onload function
in my javascript.
I must have missed something fundamantal in this attempt. Really hope
someone can direct me a little.
Thanks,
Jason

Well, I think all these might be due to the argument TargetFrameName
passed to the method Navigate() of the Web Browser control. When a new
window (either a name string in javascript or boolean true for new
window in a C# assembly) is specified for the argument, the object
instance lives. Otherwise, it dies.
I now need to figure out the right value for it. I used the html frame
name for it in a direct embedding. The control won't display. I don't
know what to pass to it in my custom C# user control which contained
the browser control.

Hi,
I have stored a menu in a database. The menu is dynamically updated and last level menu items contain the object type that should be instantiated. I am looking for a way to instantiate the object dynamically without an enormous select case statement. I can't find nothing in the docs... Any ideas?
To make things clear, what I want to do is something like this:
dim objType as new String("CustomerObject")
dim obj as new objType

My goal here is to get access to open a folder that is related to the
current displayed record. For example, if the customer's last name is
Smith, i want the folder "//server01/jobphotos/Smith" to pop up when
you click the Job photos button.
So far this is all I have for it...
RetVal = Shell("explorer /e,/root, //server01/jobphotos/Smith")
This works on a one time basis, but i need it to be variable so it

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
