I did a finer reading of the documentation[^] for the DomainUpDown control class...
The user can also enter text in the control, unless the ReadOnly property is set to true (the string typed in must match an item in the collection to be accepted).
Well, apparently the DomainUpDown control isn't what I'm looking for.

I would just use a ListView or ListBox.

Hi.
I'm writing an application with Compact Framework 2.0 SP 1. I want to apply the [STAThread] attribute to the main method, but there seems to be no such attribute. I get offered the MTAThread attribute, but not STAThread. Of course, the compiler doesn't find either. It just seems to be missing in the referenced assemblies (System.dll). I didn't find anything about this problem on the web, so could anybody help me, please? I'm quite desperate. I already reinstalled the CF 2.0, no success. Nobody else seems to have had this problem, ever. Help!!!
Thanks!

You can't do that. STAThreadAttribute is not supported in Compact Framework.

Hallo,
the data shown in a datagridview come from the datasource, which can contain e.g. a Dataset or a datatable. By modifing them the grid display is also altered.
To change data you can do e.g.
datatabel1.rows[23][53]=datatable2.rows[65][2]
//copy cell in row65 column2 to row23 column53 in datatable2
or
datatabel1.rows.add(somedatarow)
I hope it helps.

You did every thing right. Are you looking under the right tab in the ToolBox? I put them under the General tab and they popped up just fine.

i did that under the general tab and data tab but it didn't work
when i search for a solution to this problem i read that there are controls should be registered before added to the toolbox
should it? and if how can i do that?
tanks for ur attention to answer me

Hi,
Does anyone ever manipulate the L1, L2 cache directly when writing managed application for Windows? Is it possible to load the whole application in L1 or L2 cache. I was told by my boss I should load my application into L1 or L2 cache for performance reason. As I've never written such code before, I'm wondering whether it can be done. Hope you guys can give me a few pointers.
Thanks,
chew

AFAIK you can't do it directly, since the processor keeps whatever it used most recently in the cache. What you can do is make the inner loop of your most computationally intensive section of code small enough that it can fit in the cache entirely. You also want to write it so the working set of your data will also fit in the data cache completely.

Rules of thumb should not be taken for the whole hand.

Thanks. Does that also mean I can't manipulate the cache if I'm writing unmanaged application using language such as unmanaged c++.net?

What kind of performance benefit do you think you'll get over the Windows Task Scheduler and the on-chip Cache Manager?
More importantly, without regard to its feasibility, what would it cost you to develop such a mechanism versus it's best POSSIBLE performance benefit? (Assuming there are no side-effects on the rest of the system, of course)
Now, recalculate that cost, throwing in developing fixes for the inevitable problems something like this will generate.
Is it really worth it?

Hi,
Pardon me. I've yet to develop an application that needs to take into consideration on windows task scheduler and on-chip cache manager. I don't have any comment on that. I was told it will be faster to move data from L1, L2 cache. I'm not sure how significant in term of performance. Do you think you can enlighten me from your experience?
Thanks,

The last time I saw that little trick being used was under DOS way back in the day. I don't see any possible way of doing it under Windows. At least that has any decent performance benefit. Remember, your application is only a few threads running in a sea of a few hundred of them. Back under DOS, your app had total control of the entire system. Under Windows, that's never the case. If you try and monopolize even a quarter of either cache with your own code and data, what impact is that going to have on the rest of the system and applications that are running?
Minimizing cache swaps for your code/data means that other code/data are going to get swapped more often. So great! You get a performance benefit for your app, but you can only get that benefit by taking the performance away from something else. In my book, that warrants uninstalling your app.
I'm not your enemy here!  Your boss is! Seriously, does he know what the cost of even attempting to develop such a solution would be?
Is minimizing cache swaps going to be the best performance benefit and use of that money? No, it's not. The thing that slows your app down FAR more is the time your app isn't even executing any code because the single processor machine is executing hundreds of other threads. If you can increase the priority of your application, your threads can get back to the top of the scheduler sooner and spend less time idling. Now that's easy to do with the Thread[^] class. But like I said, you can't get a benefit for free.

I'm looking for a good, free .net profiler to generate reports on function execution times.
Apparently .net has one built in, but i can't find anything about it.
Can someone point me in the right direction, or recomend an alternative?
Cheers
Tris

You could always try this one:
http://nprof.sourceforge.net/Site/Description.html[^]
I believe that the profiler you are looking for in .NET is in VSTS (I only have Professional so I can't help you there).
Arthur Dent - "That would explain it. All my life I've had this strange feeling that there's something big and sinister going on in the world."
Slartibartfast - "No. That's perfectly normal paranoia. Everybody in the universe gets that."
Deja View - the feeling that you've seen this post before.
