webbrowser control - visual styles

22-Jun-04 5:43

Anything that'll work in VB6 will work in .NET (doesn't matter if you use C# or VB.NET - it all compiles to IL and you only need class library support for this, which all manages languages can access). That doesn't always mean it's as easy (since the VB VM hides the automation details).

First, make sure you've registered your ATL server you found and create an interop assembly from it (using either tlbimp.exe or have VS.NET create it - it all works the same). Make sure that is referenced by your project. This is the RCW (Runtime Callable Wrapper) that you need.

As far as how to use it, I really can't help you there, especially since I have no idea of what project you're talking about (a link would've helped).

Finally, don't assume that types in .NET translate to types used by the ATL component. For example, the DragDropEffects may not have the same values as what the ATL component is expecting, just like the IDataObject interfaces are not the same between .NET and the Shell APIs (though they are transformed internally at a point).

Here's the english version:

Register the altBind.dll and run clipx.exe. You can drag a object from Explorer to the "Clip/Drop" button. All the VB source is included.

Is your application including a manifest to bind to version 6 of Comctl32.dll? If you are using .NET 1.1 you can call Application.EnableVisualStyles();.

i'm using 1.1 yeah, but Application.EnableVisualStyles(); doesn't seem to work for the browser control.

Heath Stewart21-Jun-04 5:12

This has been a common problem, usually fixed by calling Application.DoEvents after calling Application.EnableVisualStyles, and calling both before instantiating a single Control (usually before calling Application.Run).

For example:

public class AppForm : Form
{
  static void Main()
  {
    Application.EnableVisualStyles();
    Application.DoEvents();
    Application.Run(new AppFrm());
  }
  // ...
}

i tried that before but didn't have any luck.

this is for EnableVisualStyles() from the msdn docs: "Note This call will have no effect for controls in the browser."

i guess i'll have to wait for whidbey :/

If you have control over the HTML, include the following meta element within your pages:

doesn't work either.

when set to "no", that meta tag doesn't seem to have any effect whatsoever even in a regular ie session Smile | :)

Read Using Windows XP Visual Styles[^] on MSDN and go to the "Using Visual Styles with HTML Content" section. See if any of the rules they specify are being broken by your HTML to improperly render the visual style.

C# Load a form into a Panel?

21-Jun-04 14:40

this should theoretically be possible according to the docs, don't understand why it's not working.

anyway, i'll look into it some more one day. thanks for all the tips.

hello guys,
I was wondering if its possible to load Form into a Panel that is located on a main Form??

I am in the process of creating an application that have multiple views that for now have 20+ Panels. But its getting out of hand as its impossible to get a view of them all. Therefor i was wondering if its posible to create forms to be placed into another form - either inside a panel or some other means?

any sugestions and code examples would be welcome. Smile | :)

No, it's not possible. Use MDI instead.

Hey Heath,

Not sure if you check out the ASP.NET board at all, but I'd really appreciate your take on a question I threw up there, considering you've basically committed the .NET framework to memory and all... Smile | :)

I try to steer clear - there's far too many questions about client-side stuff, and the majority of people just don't understand what ASP.NET is. I typically spend more time explaining why you can't popup a window using pure ASP.NET than anything.

I'll check it out, though.

Urgh.
Ok thanks for the fast reply.

Btw. is there anyway using MDI forms to remove the borders, and then show the form in full size so its not possible to see that its MDI?

I have only played around with alittle so its only a thought before i look closely at it.

cheers

Simple Question: Get Time from terminal

21-Jun-04 3:27

Not easily, no. For that you really have to understand the Windows messaging system, styles, P/Invoke in .NET to use all that, and dialog resources in Win32.

I would suggest re-designing your controls. You could, for example, use a UserControl or some other Control derivative and just dock it (using DockStyle.Fill). If the UI and implementation is already in a form, then abstract them to a UserCotrol (or something) and use that in both forms.

Casting DataSet problem

marspd21-Jun-04 1:00

Hi people, hope you can help me.

I have the following code

public class TestDS : System.Data.DataSet
{
}

public class DataSupplier : dalBase
{
public DataSet GetSupplierList()
{
HybridDictionary parms = new HybridDictionary();
return Factory.GetDataSet("GetSupplierList", parms);
}
public TestDS GetSupplierList()
{
HybridDictionary parms = new HybridDictionary();
return (TestDS)Factory.GetDataSet("GetSupplierList", parms);
}
}

The first method works fine and returns a normal dataset. However, I need to create a strongly typed dataset hence the casting in the 2nd method to my own subclassed dataset. Trouble is when I run this I get a the dreaded 'Specified cast is not valid' error.

I was sure that I should be able to do this but it just doesn't work. Any ideas anyone?

Cheers

Paul

First, it is not CLS-compliant to have more than one method with the same name that differs only by the return type. Instead, rename one or both of your methods, such as GetTestSupplierList or something more suitable.

Second, your DataAdapter (or however you're filling your TestDS) should actually fill an instance of that TestDS class. So, perhaps add a Type parameter to your Factory.GetDataSet method, something like this:

public static DataSet GetDataSet(string storedProc, IDictionary parms, Type dsType)
{
  // Do some argument checking...
 
  if (dsType != typeof(DataSet) || dsType.BaseType != typeof(DataSet))
    throw new ArgumentException("Not a valid DataSet type.", "dsType");
 
  DataSet ds = (DataSet)Activator.CreateInstance(dsType);
 
  // You're got your generic or typed DataSet - now just fill and return it...
}

You should be able to cast it, since the return of GetDataSet still returns a DataSet. Such a method works fine in our enterprise application.

My first C# development at work needs to connect to a unix box and transfer files (both directions) using SSH (secure shell) and SCP (secure copy). Can anyone recommend a product/component/code to do this? I've come across Putty and SSHActiveX etc but I'd like a .NET solution if at all possible. Thanks.
