Use serialization. Look for the System.Runtime.Serialization namespace. There you'll find BinaryFormatter and SoapFormatter classes. Serializing and deserializing is very simple

// serialize
mystruct s = new mystruct();
using (FileStream f = new FileStream("Test.bin", FileMode.Create))
{
   new BinaryFormatter(f).Serialize(s);
}

// deserialize
using (FileStream f = new FileStream("Test.bin", FileMode.Open))
{
   mystruct m = (mystruct)new BinaryFormatter(f).Deserialize(s);
}

Just make sure that the struct and all its members have the [Serializable] attribute set.

Just replace this

<br />
struct mystruct{<br />
int num;<br />
string name;<br />
bitmap mybmp;<br />
};<br />

with this:

<br />
[Serializable]<br />
struct mystruct{<br />
int num;<br />
string name;<br />
bitmap mybmp;<br />
};<br />

Windows Services do not have a user interface and are often run without a user logged on. To create a Windows Service derive from the System.ServiceProcess.ServiceBase class. To write a controller for your Windows Service create a WinForms application and use the System.ServiceProcess.ServiceController class. A little searching on those classes and you should be able to find plenty of samples.

U have to fill it from DataBase or u trying to fill it manyally by filling urself.
if u not using dataBase the method Add have no way to do not work.
Or I suggeset you to open new C# Windows Application then drop one ComboBox and begin filling using Add method.

I hope this heslps you...
