Right click "reset". Assuming that you are using Vs.net

Hallo,
while performing, my program serializes some data into files. My problem is, that these files are not deleted when the program is uninstalled.
Is there any property in the setup project which can achieve that?
Thanks for your help,
Björn

You can create a DLL with a custom installer (a "custom action") and, on the UnInstall method, you remove the files.
Read the System.Configuration.Install.Installer docs for more information about this.

im trying to write a effective file sharing program. The program should brake down a file into pieces (byte[]) and send them over the network to the client. The client should then return a recipt or something, letting the sender know that he just recieved the byte[] then repeat. in the event the client never sends a recipt, the sender will then resend the previous byte[]. What im asking is, what is a efficient way and effective way of doing this. obviously hashcodes would need to be employed to ensure the client has recieved the correct data. any ideas/code examples on how to do this would be much appreciated.
as it stands now i wrote a dll that automaticly deserializes (spelling),compresses,encrypts and sends it. the recieved does the oposite and then sends the newly formed object back. is there a easyier way of doing this?
thnx,
jesse

Depending on what you're trying to achieve, this is not easy.

Unless you're using UDP packets, there's no need on doing this. TCP assures that the connection is either dropped or the packet is received.

Again, TCP assures that, and handle packet retransmissions automatically.

is there a already established class or dll that would do the job ? i have noticed that the packets do send out of order sometimes.

hello i have a custom control with 2 buttons i need the control the raise an event with the parent only when 1 of the buttons is pressed. what is the proper way to do this?

You should make a custom event handle to your control.
The way to do this is to create a delegate and a evet handle to you control like this
public delegate void ControlButtonPressedHandle(object sender, EventArgs e);
public event ControlButtonPressedHandle ButtonPressed; and then create a method that invokes all your delegates
protected virtual void OnButtonPressed(EventArgs e)
{
if (ButtonPressed != null)
ButtonPressed(this, e);
}Once you have done al this you can add a delegate to you button to rise when it is clicked and invoke all you custom control delegates
private void button1_Click(object sender, System.EventArgs e)
{
OnButtonPressed(new EventArgs());
}
Finaly your control now has a button pressed delegate.
Hope this helps you.
I hope you understand...

and how would i use this to notify the parent that this happened?
|
|
|
|
|
into the paren constructor add the following
myControl.ButtonPressed += new ControlButtonPressedHandle(myFunction);
and into it's class add the following function
void myFunction(object sender, EventArgs e) {
}
this is what a delegate is for 
I hope you understand...

I agree with you but why make your own delegate when you can use the normal EventHandler?
|
|
|
|
|
i dont know what your talking about im using multiple buttons in a control and i only want the event to happen when a specific button is pressed
|
|
|
|
|
lol in that case double click on the button in the designer and write there your code
I hope you understand...

i used my own delegate because in my opinion it makes the code more inteligible, easier to understand when it evolves into a mass of characters that nobody can understand (not even me sometimes)
I hope you understand...

Hi
Programmers likes dividing their code to several DLL. However, is there any rules to divide the code? By function, by class or by other factors?
Thanks

Yes:
1. When something is reused, it goes to a DLL.
2. When something needs to hide classes, data and references to other DLLs, it goes to a DLL. E.g., Data Access Layers - we have a rule where no project but the DAL should use a SqlConnection or an OracleConnection. When classes or data need to be hidden, but public to an assembly, we use the 'internal' keywork and put it on a DLL.
3. When the project is mature (i.e., we're on the optimization phase) and something is slow to load, and will not be used on the application startup, it goes to a DLL.

you only use dlls if you wanna reuse that specific code and share it among more than one program and the rules varry depending on how you want the dll to be used you may for instance want to make some sort of graphics dll with might include several classes or you may just want a single class in your dll such as a simple custom control that you share between a few programs. they are also usefull if you want to update only specific portions of your software without updating the entire release. sometimes it may just be simpler to contain all your code within a single .exe file as it makes installtion easier becuase dlls need to be registered with the os and the more seperate compenents your program has to deal with the greater potential for error/corruption as well as problems with updating a dll and breaking the code in your exe known as "DLL HELL". i hope this helps
