I agree that it's dangerous, but since C# keywords != VB keywords != C++ keywords != python keywords != cobol keywords, etc; the CLR needs to have a way to handle something not a keyword in the language it was written in but that is one in a different language that wasn't considered when the class was originally written.

Excellent, thanks. I stand corrected on the "This feature should have been left out" bit. 
Cheers,

Both Colin and Vikram are correct. It is possible to do by prefixing the enum field with the "@" symbol but it really is not recommended.

Good Day,
Ever since I've used DLL files, I'm always plagued by the problem of detecting whether they exist or not.
For example, A.exe uses A.dll , and then I delete A.dll then run A.exe
A.exe will run successfully even if A.dll does not exist, it will however crash when some function from A.dll was called.
Is it possible to display "Cannot find A.dll. Application will now close." message?
I don't want to use File.Exist("A.dll") in Program.cs, is there any other way to accomplish the task?
Thanks!

If the DLL is optional, you could catch the exception that is thrown when the DLL is not present.

Thanks for the reply.
What if the DLL is really really needed? And I want to throw an exception before the main form starts (in program.cs)?

I thought your situation was that the DLL already is NOT there!

You could try loading all the DLLs you need at the beginning using Assembly.Load(), I suppose....

Yup, after searching Google, I stumbled upon this solution. I am using Assembly.LoadFrom inside a try-catch block.
Thanks!

I am connecting to an MS Access Database with one of the tables containing an image field (OLE)
When I created a report that display that image, I faced 2 problems:
1- The resolution of the image turned very bad. So, how to control this?
2- How to adjust the image size to dynamically display proportional height and width that fit on A4 paper?

Hello,
in an application developped via ASP. if i run a table it take about 1 seconde to get the result.
but running the view of the corresponding table take about 3s.
Note : the view contain a complexe query.
So from where to get data from table or view in order to optimize my search.
best regards

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.

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

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;
}
}
