ManualResetEvent waitHandle = new ManualResetEvent( false) // non-signalled NumberGenerated.Invoke( this, new NumberGeneratedEventArgs( value))

Internal class NumberGeneratedEventArgs : System.EventArgs VSNetVbHarry was so nice to do this work. Passing arguments to a threaded LongRunningProcess. How to pass ref parameter to the thread,Ĭhange paramters of thread (producer) after it started. Please see my past answers for more detail: The thread wrapper is very important to avoid parametrized thread start and for better encapsulation in general. It's responsibility of the UI thread to add an event handle to the invocation list of event NumberGenerated. On a wait of the handle, a thread is switched out and never scheduled back to execution until waken up by the call to ManualResetEvent.Set, timeout or Abort called in any other thread. Note the use of event handle - this is the way to use long-living thread and keep it in a wait state without wasting any CPU time. For now, it's important to make a skeleton: generate some number and fire an event with new value also, it can be started/paused/resumed/aborted. Later on, you can add some random algorithm, input numeric ranges in it. This is a code sample created on OP's request:įirst, let's make a thread wrapper.

I want an application where I can put Lowest and Highest number and then the program will show the random number between them automatically. Lable Ramdom (lbRandom): this is where the 'random number' between Lower and Higher number show up. Button Random Begin (btRandom): button to activate the program. Higher number (txtHigher): This is where I put the Highest number. Lower number (txtLower): This is where I put the Lowest number. That 'random number' application is my small first test before I can do that program.Īs you can see, my application has 4 main parts: I want to make that application because I have a girl shoes shop, so I want to make a program show Random product with its price in my computer. I created an VB application by Visual Studio 2008. Well, I am not an English or American., so I am not good at English, sorry about that.īut I really need help in this situation. I'm a new member here and ofcourse, I'm a newbie of VB.NET, too.
