I have a buffer object which is basically just an array of Int32s - is there an easy/fast way to write the whole buffer at once to disk in C#? Or, for that matter, to a SQL Server Blob?

Oops, I meant an array of UInt32

It's a bad idea. You have to declare an event in the user control, handle the cell changed event in the user control and fire the user controls event. Your form should handle the event fired by user control.

When creating .NET Assembly for COm Usage manualy, there are many steps:
1. compile the type library you have created through C# compiler
2. use the type library exporter utility.
3. you need to create a resource script for your type library using the
command IDR_TYPELIB1 typelib "YourLibrary.tlb"
4. you need to recompile the type library with the new resource file added
i coudn't understand step number 3. what is the necessity of creating the
resource script, and is it done automatically when using visual studio to
expose the assembly and do the job for you.

There is a MS page about the requirements and some resources here: http://www.microsoft.com/learning/mcp/mcts/winapps/default.mspx[^]
I used the MS self paced learning books, which are absolutely rubbish so I can't recommend them, but I passed no problem so they were obviously enough. I'm not sure the certs are that valuable any more, I probably wouldn't have done them if it wasn't for my company paying because they wanted the points in the MS partner program.

You shouldn't do this. What about people who don't like using mice.
Why are you trying to disable the keyboard?

You can use e.SuppressKeyPress = true in KeyDown event.

I sugest you have a column( called user id) hidden on the data gridview. When you check 4 boxes out of ten then you can use something like.
dim id as integer()
for i as integer = 0 to dgv.rowcount-1
if dgv.rows(i).cols(0).value = true' this is your checked column
id = cint(dgv.rows(i).cols("userid).value)
end if
next
I wrote this code in the reply window you may have to change some few things. id should be public to your project. Once you have populated user id's in the array then
In your new form load you can use something like
for i as integer = 0 to id.getupperbound(0)
sql = "SELECT * FROM table where field = " & id(i)
'decide what you can do here
next
