this.Controls[i].GetType() == typeof(System.Windows.Forms.TextBox)
This will not be true for a class descendant of TextBox, that's why.
Standards are great! Everybody should have one!

You often cannot delete items from a collection that you're doing a foreach on. I usually build a list of items to delete, then iterate over that list, to do the deleting.

Hello all,
trying to write a console application that will act as a network bridge between 2 network adapters. This means i need to pass everything from 1 adapter to the other both ways. The names of the adapters is known,
Would appreciate any help,
Amir.

|
|
|
|
IIRC you can bridge in the Network Connections window, no code required.
|
|
|
|
|
I know i can do so through network connection window but i need to do it through code...

|
|
|

You will get some hits when searching CP for "network sniffer" or something similar.

I have a console application spanning multiple methods and functions, and based on a flag value I wish to abort program execution.
Is there any other method other than break(which cannot be used always)?
Thanks!

You basically want something like this, I can't help more without knowing more.
static bool abort;
static void Main(string[] args)
{
while (!abort)
{
DoStuff();
}
}

Have you tried Environment.Exit() ? It worked for me
|
|
|
|

Thanks. Environment.Exit() works. I was not aware this function.

Environment.Exit() not working for you?

I am creating a custom control like listbox. So I need to implement CollectionProperty which will open collection editor to add the items at the design time. I succeeded in creating collectionclass and item class. But I am not able to set this to property. It shows (collection) in the property. But when I open collection editor and add new item, it is showing System.Object. I am not able to get my item class properties there. Could any one point me to the right direction to implement collection properties. Any urls' also will be helpful.

You need an indexer (aka Item) that sets and gets the Type. Also the Type, needs a default constructor.
|
|

|
|
Thanks, Could you please show me a some sample code or article where I can find more information on this ?

Hello,
N a v a n e e t h wrote: I succeeded in creating collectionclass
I guess like that:
public class YourItemsCollection : CollectionBase, IDisposable
{
}
For this class you have to write an converter, which inherits from "System.ComponentModel.ExpandableObjectConverter".
public class YourItemsCollectionConverter: ExpandableObjectConverter
{
}
In this class you have to override following methods:
public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] filter)
The "YourItemsCollectionConverter" has to be set as an Attribute to "YourItemsCollection":
[TypeConverter(typeof(YourItemsCollectionConverter))]
This article[^] shows it very good!

Hi,
I am a new to Visual Studio.NET but not to development and require assistance; after downloading Plug-in samples from codeproject and the Microsoft sample,
and finding issues with deprecation etc using Visual Studio 2005 .NET.
The MS sample performs some form of conversion and I suspect this is in relation to the PluginCollection class, which now causes an issue with
ConfigurationSettings being replaced with ConfigurationManager, and naturally the following type cast is no longer supported:
m_plugins = (PluginCollection)ConfigurationSettings.GetConfig("plugins");
I am attempting to develop a plug-in host capable of displaying usercontrols plugins on a panel in the same manner as the codeproject sample
(ExtensibleUI_demo) but using the Microsoft framework by adding the IPlugin Interfaces to the welcome class. E.g.:
public partial class Welcome : UserControl, IPlugin
I have managed to develop an application based on the ExtensibleUI_demo to work, but the plug-in name details are not added to the listbox, and I am not sure
how much of this framework is no longer applicable or appropriate best practice.
Can anyone assist? it is my intention to use plug-ins to replace database forms, displaying them on a parent container such as a panel.
Regards

Did you see my article on creating Plug-ins with .NET? It even has a sample application to test the plug-ins.

Thanks Joseph,
No I had not noticed your article; the article is well documented and clear, the demo code what can I say this is exactly what I was trying to achieve, its good to see someone else also appreciate class diagrams. I will revisit my prototype as I did manage to get a prototype working with the support of an article “Plugins in C# by Redth”, obviously there is nothing wrong with this approach yours lends itself to my personal style and approach.
Greatly appreciated.
