Its your choice really. If the table contains all the data you need and its quicker, use it. If not, use the view.

The only real way to tell is to benchmark the time it takes to do whatever you need to do with the data.

And what is not working? What do you use to find and then replace? Show some code.

Try:

richTextBox1.Find("XX");
richTextBox1.Text = richTextBox1.Text.Replace("XX", text);

Hello

I am using multicast delegate as follows, but the effect in the server is undesirable:

Thing.OnEvent1 += new IThingEvents_OnEvent1EventHandler(OnEvent1);
Thing.OnEvent2 += new IThingEvents_OnEvent2EventHandler(OnEvent2);
Thing.OnEvent3 += new IThingEvents_OnEvent3EventHandler(OnEvent3);

The problem is that the (C++ COM) server it thinks it has all the connections for each event.
So in the below example it trys to send the event 3 times. Apart from the unecessary processing, I am worried it is making the inter-process call each time (the incorrect calls are being thrown away on the client side somewhere).

HRESULT Fire_OnOrderCancel(lots of params)
{
HRESULT hr = S_OK;
T * pThis = static_cast<t*>(this);
int cConnections = m_vec.GetSize();

for (int iConnection = 0; iConnection < cConnections; iConnection++)
{
pThis->Lock();
CComPtr<iunknown> punkConnection = m_vec.GetAt(iConnection);
pThis->Unlock();

IDispatch * pConnection = static_cast<idispatch*>(punkConnection.p);

if (pConnection)
{
CComVariant avarParams[20];
//set avarParams
CComVariant varResult;

DISPPARAMS params = { avarParams, NULL, 9, 0 };
hr = pConnection->Invoke(1, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, ¶ms, &varResult, NULL, NULL);
}
}
return hr;
}

What c# thing do I need to use to get the desired behaviour, namely events to be fired once and the c# client to do the correct delegation?

Many Thanks

Casting to inhering type from inherited type

Hey!

I got a problem with a class of mine inheriting from xmldocument. When I have an actual xmldocument I can´t cast it to my class, I get System.InvalidCastException. Why is this? I have done the same with for instance another class inheriting from UriBuilder.

Because the instance you are trying to cast is obviously not of your inherited type!

This is what I tried:

class test : XmlDocument
   {
       public test()
       {

       }

       public void testing ()
       {
           test t = new test();
           XmlDocument doc = new XmlDocument();
           t = (test)doc;
       }
   }

Why was the message deleted? Because the OP said the proposed solution didn't work? That's not a very good reason as now no one else who runs into the same (or similar) problem will know not to try that approach.

So I can´t cast to a more advanced type, but casting to a less advanced is okay.

I think you need to study inheritance and polymorphism a bit more. It takes a while to get to understand it, but once you do, it all seems natural.
