Ok thanks! Will do! I'll read and write it to the StandardInput as a byte array. Thanks again.

The following is an example of delegates and events I found in a book with a few modifications. I am having trouble trying to make the program work using Delegates, I am trying to insert a message from one class to another classes ListBox. Please help before the reactor goes critical. I’d appreciate any help, please be specific.
Do All Delegates need to be instantiated in the Main menu as every example I see does.
Thanks,
Michael

No. Delegates can be declared in classes or in namespaces.
FWIW, in the latest version of .NET, you don't really need to define your own delegates anymore because of System.Func and System.Action. For example, you can replace your DelegateReactorMessage with Action<string></string>:
Old code:
public delegate void DelegateReactorMessage(String message);
...
public partial class FormStartReactor : Form
{
static FormReactor FR = new FormReactor();
DelegateReactorMessage delegateReactorMessage = new DelegateReactorMessage(FR.ReactorMessage);
string message;
public FormStartReactor()
{
InitializeComponent();
}
}
New code:
public partial class FormStartReactor : Form
{
static FormReactor FR = new FormReactor();
Action<string> delegateReactorMessage = FR.ReactorMessage;
string message;
public FormStartReactor()
{
InitializeComponent();
}
}

Thanks, I appreciate the help but do you know why my example doesn't work and how I can fix the problem.
|
|
|
|

I tried to execute your code. But it is not complete. If you need someone to try it, post full code. Your code lacks InitializeComponent method.

I have been building a program for some time now. And now I´m intrested in how to get paid for my application. I will put it out on the internet and make people be able to drive the program for a trial period. I wonder which different ways there is to get paid? I want that the customer automaticly recieve a activation code to the application after they have paid... Please give me some hints to solve this.
Best Regards
Sebastian

Communicating, more descriptively than your subject line here, with your potential clients would be a good start.

Well, 'hi' is not really a helpful subject line. Instead of attracting people who know about your issue, you attract people who are inclined to express frustration at your communication skills.
Most people worry too much about security. Your app is C#, it can be decompiled. Worry a bit, but don't inconvenience people who want to pay you, they will hate you for it.
It's really hard to help you without knowing what the app is. If you can't afford to buy advertising somewhere like CP, and if you can't direct market your app, you're going to enter a world of shareware sites where I would expect a limited return. Of course, advertising on CP only makes sense if it's a developer tool, but it needs to be advertised *somewhere*. Even if you just put together a website and buy google ads.

Please read this if you don't understand the answer I've given you. If you're still stuck, ask me for more information.

If you're giving out a trial version, you need an expiration date when the trial period is over. Also you need a way of detecting if they've set their computer's date back to use the program longer. So if people find your program useful, they'll have to pay to get a version that doesn't expire.
Another possiblity is shareware, where there's no expiration date, but people are encouraged to pay a small fee for things like more features, updates, support, etc...

Thanks for replying but what i really want to do in my form is display all the files that need to be copied from one place to next and then display each file status in the textbox once they are copied. But if run them in load event the texbox is not update until the entire form is loaded.

Does anyone know why the Clipboard will not work while it's nested within the iTunes event handler? I cannot figure this out for the life of me. Source noted code below.

InitializeComponent();
try

}
catch(COMException)
{
Application.Exit();
}
}

This is not a framework bug. It is probably ITunes hijacking your clipboard. I have seen similar behaviour in Adobe Acrocrapread and VNC.

I know this is a simple question but I would like to know How and Why this works;
Lets say I have two forms : Form1 and Form2 where Form1 is the main form. I am creating a Form2 variable by clicking a button in Form1 as seen in the code piece below.
private void button1_Click(object sender, EventArgs e)
{
Form2 myForm2 = new Form2();
myForm2.Show();
}
Why am I able to see form2. Because myForm2 is a local variable and just after it is shown, the function button1_Click terminates. So I mustn't be able to see Form2.
NOTE-1 : If you try the same with MS VC++ you will not be able to see Form2.
NOTE-2 : I know in .NET variables are not deleted when they are out out of scope. Garbage collector does it. Bu in an other function I tried GC.Collect(); which forces the garbage collector but Form2 still remains, it is not deleted.
Regards

Hi,
a variable is visible ("in scope") as long as you are within the first pair of brackets {}
that encloses its declaration, so myForm2 lives only inside your button1_Click method.
The Form it refers to is an object, calling Show() makes it visible AND keeps it alive,
even when button1_Click returns and hence variable myForm2 fades away. Once visible, the Form
does not need the variable, it has its own life. You would have to close the Form somehow
(by clicking a Close box, or by calling the Close() method) to end its useful life and make it
collectable.
|

Thats the point; "Once visible, the Form does not need the variable". I just can't understand why and how?, sorry
But thats not the case in MS VC++. Once you create a dialog class and if the object is out of scope, the form is also deleted. Right?
There are strange things going behind c#
