I have created a diagram building application (something
like a "diet Visio"  ) with an abstract Shape class every
drawing shape have to inherit.
My program has plug-in support so users can create their
own shapes (derived from my abstract Shape class). The
plug-ins are placed in a separat folder. The dll files in
this folder are dynamically loaded at startup.
Of course, I want my program to be able to save and load a
drawing. I use the BinaryFormatter and Stream classes to
serialize the drawing. This looks ok, but when I
deserialize the same file, I get an exception
(i.e) "Rectangle.dll not found" (or something like that),
because this file is a plug-in, dynamically loaded at
startup.
So (finally) my question is: What is the best way to
serialize and deserialize an object (consisting of
dynamically loaded objects) like my drawing object?
Any help and suggestion are appreciated.
Øyvind.

Hi,
I'm trying to get several browser panels on top of each other each with a different opacity. I was wondering if there was any way of setting the opacity for a panel, or if any one had any ideas as to how to go about achieving this effect.
thanks
dror.

Please take a look at this article on devhood, http://www.devhood.com/messages/message_view-2.aspx?thread_id=70534
What I want to do is essentially have a class which contains all static members of my applications settings and have it serialized out.
Something along the lines of this,
class MySettings
{
public static bool isConstant;
public static bool doReports;
}
After serialization using the XmlSerializer class, I hope to get something like this,
<?xml version="1.0"?>
<appSettings>
<add name="isConstant" value="true">
<add name="doReports" value="false">
</appSettings>
The main reason for serializing this is because the App.exe.config is read-only, so any changes to the settings don't persist. This is where the serialization comes into play. If I can get it to output into the xml file above, I'm golden.
The problem now, is getting it into the correct format. I see two problems with this.
One, the class contains all static members so when I call XmlSerializer.Serialize( <stream>, <object to serialize> ) I don't have an object to use.
Problem two, for each member variable how to output the xml <add key="isConstant" value="true" />, etc.
This is about as far as I get . . .
[XmlRoot("appSettings")]
class Settings
{
public static bool isConstant;
public static bool doReports;
}
Which as you can see, isn't far.  I don't know how to have the <add> element for each member variable. It won't let me add [XmlElement("add")] before each member variable. (it complains about using the same element name) And I don't know how to get the correct attributes into the xml.
Any ideas? Or better ways of doing this?
Thanks.

Is there a C# equivalent of the VB.net keyword Shared?
IE:
Public <big>Shared </big>Function DoSomething(ByVal MyValue As Integer) As String
{
'do something
}

Hi all,
I am trying to figure out what I need to do to write an Add in for internet explorer using C#.
What interfaces do I have to implement and where is the documentation for the IE object model.
Any help will be appreciated.

Thanks

The same as you you add class to other projects. Add its assemblies to your project with ADD REFRENCE.

Hi guys,
I have System.Web available,
but I don't have System.Web.Services avalaible. What should I do?
Thanks

Right click on REFRENCE in Solution Explorer andd click add refrence. Add your namespace from the list. The same way for your other question but you have to browse your dll .

Hi All,
I add a comobobox to my form and I can't use the mouse in the edit portion. I can use it to click and move the caret, but if I try to select anything it doesn't work. Anyone know what this is? I do have the style set to the one where you can edit the box (don't remember what it's called at the moment though).

Its a bug in .NET 1.0, fixed in 1.1.

First thanks,
Second, how would I start using the .NET 1.1 controls?
Thanks!

That is a bit harder to answer, if you are using VS.NET 2002 you are stuck with .NET 1.0 so long as you use that for building/debugging your application.
If you have VS.NET Professional or Higher (not Academic) then you should try to get the $30 upgrade to VS.NET 2003 so you can take advantage of .NET 1.1 right out of the box.
If you can't upgrade, or don't want to; you can still make use of .NET 1.1, its just a LOT harder to do.
First, I recommend getting, installing, and learning NAnt[^] for building your application. The samples and documentation are thorough enough that it'll only take an hour or two to work out what you need to do to duplicate your VS.NET build setup in NAnt.
Once you do that, you can have NAnt target .NET 1.1 for the build and your application will be use .NET 1.1 by default, only dropping to .NET 1.0 by using a config file.
Debugging is a bit harder to do. What I did was start my application, then use VS.NET's Attach to Process command to debug that process while it was running. A very large PITA but it got the job done while I waited for VS.NET 2003 to arrive.

Thanks again for the help James.
I just have one more question. I did some reading at the NAnt site and noticed that it doesn't seem to have support for MC++ (It has a task that wraps the "cl" complier, but I don't think this works for MC++). Am I right in assuming that? If that's the case I guess I'm SOL unless I get VS.NET 2003.
Thanks again James!

Hi everyone...
if i select a node in a treeview that displays a panel on the form, how can i dispose of that panel after another node is selected?
I don't want to have to use the
panel1.Dispose();
method whenever a different node is selected. Can someone help a gnuB figure this out?
thanks
.gonad.

I'm not sure if i've understood your Problem, but what about storing a reference to the active panel and call the Dispose()-Function to this, so you don't have to close all Panels.
