Hi, As well as the class name, you need to know what assembly the class is contained in. There are different ways of doing this, but just lifting a bit of code from work: Assembly assembly = Assembly.LoadFile(@"c:\myassembly.dll"); object dynamicClass = assembly.CreateInstance(classNameFromDb); Not sure that helps as you end up with an untyped object. The way we do it here is to make the objects we create dynamically implement an interface, so the second line actually looks more like IDynamicObject dynamicClass = assembly.CreateInstance(classNameFromDb) as IDynamicObject; This way, we can then call the methods the interface specifies. After all, creating an instance of a class is little use if you have no idea what the object does. This is why defining an interface is useful. And don't forget the gotcha, the trap I always fall in with this, its not just the type name you need, but also the namespace. eg. "MyNamespace.MyClass" which you need to pass to CreateInstance.

are you trying to write in from a visual-studio properties window? because they will disable that option and just write \t, search the designer code for the label's text, and do it by hand, if there is a @ before the string, then erase it... If the problam is continues, then something doesn't make sense, give a part of the code...

Hi Manu_81, http://www.codeproject.com/cpp/RegViewer.asp[^] maybe it is some helpful to you

Yes. I believe it will bootstrap it; that is, if setup detects the .NET framework is not installed, it will download and install it as part of setup. That way you can distribute a smaller setup file.

They allow you to utilize multi-core and multi-processor machines far more than a single-threaded application would. They also keep your UI thread responsive, which end-users will praise you for. I recommend that your DLL do its heavy lifting on another thread. While that thread is running, have the dll just display a "loading..." or "please wait..." dialog of some kind. Then, when the thread is finished, return the results to the UI thread for display to the user. You can use the BackgroundWorker[^] class to help you do this in a simple manner. The only other option would be to make a call to .Update() your form from your dll or call Application.DoEvents. However, there are caveats and gotchas associated with those solutions; the best solution is to do heavy lifting on a background thread.

But my app is console app. Which does not mean that your application cannot create a hidden window for the sole purpose of receiving notifications.

This was answered earlier today, here[^].

how can i open gif files?

It doesn't "get around it". It just fire an event on the correct thread. It insulates you from the details of getting code that modifies a UI control to run on the correct thread. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome

Consider using class Monitor

Yeah, so send it a WM_DEVICECHANGE message - it will catch it and think something has changed, so will refresh. Ryan "Punctuality is only a virtue for those who aren't smart enough to think of good excuses for being late" John Nichol "Point Of Impact"

Also, I just double checked the code. The NewMonitorDetailsArray property should have been static - so I've corrected that (see updated previous post) You can access the ArrayList of all NewMonitorDetails by using NewMonitorDetails.NewMonitorDetailsArray You cannot set this as it is controlled by the class. But you can perform any methods on the ArrayList (like Add) so you can modify the contents of the array.

Alternatively you could drop a Flash Player on your form. This might give you more control over playing of the movie and the ability to handle events from the control in your .NET code. (Add it to the toolbar in VS by selecting it from the COM component list.)

Perfectly working. Thanks a lot. :thumbsup:
