Hi !
I would like to implement the Progressive Disclosure Controls in windows forms using c# . The Progressive Disclosure Control is the same when you use the add/remove programs from control panel the particular row gets expand when its clicked .
Can anyone give a ref. or sample code for this kind of implementation.
Thankyou

I was watching to see if anyone would reply. So I'll make an attempt. I've done some reading on this, and it's a bit confusing. Progressive Disclosure is a UI pattern, and on MSDN[^] they talk about Prog. Disc. Controls like they're just arrows.
Start with the MSDN article, if you haven't already. Other than that, I myself am interested in whether there really are standard/custom controls like f.e. the one used in Add/Remove programs.
Visual Studio can't evaluate this, can you?
public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

ConstructorInfo ctor = LocatedType.GetConstructor(BindingFlags.NonPublic|BindingFlags.Instance, System.Type.DefaultBinder, new Type[] { }, new ParameterModifier[] { });
I've just been creating some code to let me unit test private methods on classes. I created the code and then thought that maybe i might want to test a private constructor in the future so i started playing with the get constructor method.
The thing that surprised me was that i need to use BindingFlags.Instance rather than BindingFlags.Static to get the constructor. Does this strike anyone else as strange?

No. When you think about it, the constructor is not a static method.

You're right. There after all specific static constructors. It just seemed that calling a ctor an instance method was going to start a chicken / egg problem.

I can answer that one as well. The egg came first. If you follow evolutionary theory here, then the egg must have come first because the chicken was the result of genetic adaptation/mutation, but the egg was there before.

i have just started working on .net remoting . well, an event is raised on some method call in the remote object. But while i assign a handler to the remote object's event property a SecurityException is raised stating :
"Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level."

Hi,
Just happened to see that same error yesterday...
check out this link http://www.codeproject.com/useritems/RemotingEvent.asp
Section solution 2.
When you implement a wrapper class which can be accessed from both client and server side you app should work
Greetings

Hi.
This is because of the remoting security. Normally types that are in GAC-registered assemblies are allowed to be serialized and deserialized, unless they're derived from:
- System.Runtime.Remoting.ObjRef
- System.DelegateSerializationHolder
- System.Runtime.Remoting.IEnvoyInfo
- System.Runtime.Remoting.Lifetime.ISponsor
you have to set the typefilterlevel to "Full" in your channel-configuration.
for more information take a look at this: http://msdn2.microsoft.com/en-us/library/5dxse167(vs.80).aspx[^]

Dear all,
Probably is the answer pretty obvious, but I have been struggling with this for the past 2 days already, and it's making me frustrated.
I got following XML file
<br />
<?xml version="1.0" encoding="ISO-8859-1"?><br />
<things><br />
<people><br />
<person id="1"><br />
<name>Bob</name><br />
<age>25</age><br />
<projects><br />
<project x="123" y="123">ABC</project> <br />
<project x="53" y="149">DEF</project> <br />
<project x="13" y="111">FOO</project><br />
<project x="463" y="435">BAR</project><br />
</projects><br />
</person><br />
<person id="2"><br />
<name>Steve</name><br />
<age>100</age><br />
</person><br />
<person id="3"><br />
<name>Maria</name><br />
<age>23</age><br />
<projects><br />
<project x="1" y="1">HOT</project> <br />
</projects><br />
</person><br />
</people><br />
<file><br />
<name>filename.ext</name><br />
</file><br />
</things><br />
How can I add in C# a new person, and acess the "people" node.. I even cut away so much code, that I ended up with following, just to print out what's in there, and it even fails:
<br />
doc = new XmlDocument();<br />
doc.Load(this.filename);<br />
XmlElement rootPeople = doc.GetElementById("people");<br />
XmlNodeList node = rootPeople.GetElementsByTagName("person");<br />
for (int i = 0; i < node.Count; i++)<br />
{<br />
Console.WriteLine(node[i].InnerXml);<br />
}<br />
I have been messing with Xmlnodelists, xmlelements, xmlwhatevers, but even after reading the first 2 pages of google results, it still doesn't seem to work..
Can somebody point me in the good direction?
Thanks,
mike

First of all, I suggest using the SelectNodes and SelectSingleNode methods instead of GetElementsByTagName since both use XPath expressions and therefore allow specifying/restricting the selection in more detail. You can for example select the (first) people node by writing
XmlNode peopleNode = doc.SelectSingleNode("//things/people");
To create a new person or more general new nodes in a XML document take a look at this Create New Nodes in the DOM[^].

Thank you Stefan, works like a charm!!

Thanks again.

I have a problem like Yanshof.
I have a class writed in C++ (I don't want to translate it), it is used to store and processing te data...but the interface of the program must be writed in C# (or VB).
It is possible to do this in a simply way (using Visual Studio 2003 .NET?) ?
How to create this solution that contains this classes in different lenguages.
Y/N ?
If yes, does anyone can show me the way, I need only a simple example (the classic "hello word" in mixed lenguage is enough)
Thanks a lot
Cheers,
Russell

A very simple way is to set some of your procedures written in C++ as exports. And using DllImport attribute in C# you can use those exports

First, thanks you for your reply.
Yes, of course, using dll I can export the 'procedures',.... but this is not exactly what I need: I need to use an entire class, his member functions and (expecially) his member variables.
I am hoping that it is possible to create a unique Visual Studio solution composed by 2 sub-solution, one (written in C++) that contains the document and the other (written in C# or VB NET) to visualize this document.
But, unfortunatly, I'm going to think that it is not possible, nobody is confirming this 'dream' to any of my posts.
Let me know
Cheers,
Russell

Use the Form.Closing event for this where you can set the CancelEventArgs to decide if the form will actually close. However I don't think that works if you end the process via task manager.
|
|
|
|
|
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
e.Cancel = true;
}
When you close it with taskmanager from the Applications menu, this event is also fired, but not when you close the underlying process via the Processes panel.
Visual Studio can't evaluate this, can you?
