Is this correct? It's not giving me the desired results. SomeFunction is returning me
I also tried an alternative approach. In the C# file, I declared an overloaded
// simulating const function parameters using method overloading
Then I called the function with only first two arguments. But that gives me an System.AccessViolationException: "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
An interface can't contain any behaviour (it doesn't have any method bodies).
An abstract class can have some behaviour allready defined and can allready store properties into fields, etc..
Choosing wich one to use realy depend on your situation.
I have been developing a vsto Word 2003 document action pane solution
. Now a trouble has come to me. It is how can deploy my build, including a word file, a dll, and some configuration files in xml format, to the share point portal document library. My questions are,
1). The word file can be upload to portal doc lib. But the related dll file cann't.
2). Even if the word file and all its related dll and xml files can be upload to portal doc library, i also confuse about the posibility of downloading related files of opening word file automatically. If the answer is yes, what is way to do so. please teach me. very thanks.
3). another thing is about the security policy, what means that how can the vsto word file be run when it is moved to a new position of hard disk from the original development place.

I've build the following, of wich I know it's not the way it's supposed to be and I also know how to fix it. I'm just wondering how it's caused.
- I open a SQLConnection
- I create a SQLCommand
- I run SQLCommand.ExecuteReader and store the readerobject in a variable
- I set the SQLCommand to null
- I create a new SQLCommand in the same SQLCommand variable
- I run ExecuteNonQuery
Doing the above will result in an InvalidOperationException with the message:
"There is already an open DataReader associated with this Command which must be closed first."
I looked to see if the setting to null and the creating a new SQLCommand actually resulted in a new object and it did.
Just for my understanding, how does this work in the background?
I was thinking the same thing, but...
I can't close the datareader as I still need it.
I tried making a new SqlCommand in a different variable, but this didn't solve the problem.
I now have two connections wich I don't realy want.
if my Program is running, and i create a messageBox that apears if there is a change in the prohramm, to get the first Focus of all the tasks, i mean if i run an application and then i open a web page and then there is the messageBox creation, how can i do that it will pop up in front of the web page or visualy, or any other application that is running in the background.
Do i need to activate the Focus function on the Form(My programm) and then create the messageBox?
