that does not tell us anything.
I don't think a PictureBox is a very useful Control, it gives more trouble than
it is worth.
I'd rather load and paint my Image myself, painting it either onto the Form or a simple
Panel. In both cases all painting must be handled by the Paint handler.
Whatever you do, for image processing, the first step is to perform the processing,
the second is to redraw it, either by telling the PictureBox to reload its Image (I guess
by reassigning its Image property), or the Form/Panel to redraw itself (by issuing an
Invalidate).

Ok, I know there are some articles and I've looked at this. This is my question though. I have a form that is a container. Lets call that form Main. Ok I have two more forms ContactList and EditContactList.
Now to open ContactList this is the code:
Form f = new ContactList();
f.MdiParent = this;
f.Show();
Now ContactList has a menu bar that is suppose to open EditContactList. So how do I make it where ContactList opens EditContactList, but the parent for EditContactList is form Main? The articles always use f.MdiParent = this;
f.MdiParent = Main(); does not work.. so if you could help me out, I would appreciate it!

Form f = new EditContactList();
f.MdiParent = this.MdiParent;
f.Show();
|
|
|
|

awesome, thanks... so this.MdiParent means the form's (this) parent (MdiParent).
|
|
|
|

Yeah. The 'this' isn't strictly necccesary but it makes the code a little clearer.

so i want to replace the å ä ö with something else, because when i return the row in a listview the ö are like ? or something like that... =(
i have tryade to save in diffirent encoding.. nothing works! anyone with the same problem as me??
i pick upp info from rowes like this:

string[] tecken = row5.Split(';');
string person = tecken[21];
anyone with good suggestions??
thanks!! peace!

UTF-8 should support Swedish characters. Are they not storing in your file correctly, or is it the listView not displaying them correctly?
|
|

i think its the listview hwo doesn´t display them correclty. beacouse i have tryade every encoding..
are i changing the ecoding throught advanced save options????
Thanks

I've tested the listView and it displays them fine.
Are you specifying the encoding to use when reading your file as I think that's where your problem is?
System.Text.Encoding swedishEncoding;
swedishEncoding = System.Text.Encoding.UTF8;
swedishEncoding = System.Text.Encoding.GetEncoding(437);
System.IO.StreamReader swedishReader = new System.IO.StreamReader("myPathHere", swedishEncoding, false);

Hi,
I have some Problems with Serialization:
I have a class B that is inside a class A:
public class A
{
[Serializable]
public class B
{
public int Number;
}
}
When I try to serialize/deserialize it with the XML Serializer it does not work.
Is it possible to serialize a class that is inside a class (so I have to search the bug elsewhere) or is it impossible (so I have to change the structure of the classes)?
Thanks
Roland

OK, found the Problem:
My class contains an IPAddress that can not be serialized by the XML Serializer because there is no default constructor. I only looked if the Attribute Serializable is set...
I tested and saw that with a simple class like the onein my example there is no problem with serializing a class inside a class...

According to MSDN, methods of IEnumerator are expected to throw an exception if the enumerated collection has been modified
For Example,
<br />
List<int> list = new List<int>();<br />
list.Add(1);<br />
<br />
IEnumerator enumerator = list.GetEnumerator();<br />
<br />
enumerator.Reset();
<br />
list.Add(2);
<br />
enumerator.Reset();
When implementing the methods of IEnumerator in our own class, we should have them throw the exception if the collection is modified.
Now I have a class :
<br />
class MyEnumerator:IEnumerator{<br />
int[] integers;<br />
<br />
<br />
public void Reset(){ }<br />
}
How to implement Reset in an elegant way, so that I can throw an InvalidOperationException when Reset is called after integers are modified?
Thank you!

Hi,
I have not done this yet, but here is an idea:
- in the object you want to be able to enumerate, keep a generation counter that starts at
zero and gets incremented every time you modify the collection (hence Add, Remove, Clear,
... all contain "generation++;")
- in the enumerator hold a copy of the generation counter, equal to the collection's
generation at the moment you create the enumerator
- in each enumerator method compare enumerator generation with collection generation;
when unequal, throw the exception.
Refinement: to reduce the risk of generation overflow, rather than incrementing all the time,
your collection could keep two generation values (current and next), that both start at zero.
Each modification sets "generation=nextGeneration;", and each getEnumerator
does "generation=nextGeneration++;" hence the generation can only increase if an enumerator
has been requested.

Yeah, I see, thanks for your neat idea.
Then my collection class has to expose an extra property, say Generation{get{}}, right?

Not really, if your Collection inherits from an existing one, you can implement
your own public override IEnumerator GetEnumerator() just like the
original collection did.
