First off I would say the big red X idea is a bad one and that you should leave the default UI behavouir as it is. If your frame has a title then it gets dimmed and that is how 99% of programmes leave it and most users understand this. A big red X may be a bit annoying.

But if you have a valid reason then how about using a transparent GIF (the picture control has a transparency colour setting) and overlaying. Just make it visible when the frame is disabled.

I understand your point. I am putting this together for a client who would like to see the "X" if I can make it work. I tried your idea with the picturebox. It almost works, but the image does not seem to support the transparency of the gif. I made the background transparent, and I made a gif with 50% transparency. But the picturebox still does not show through what is under it. It is as if it is showing through to the background image/color of the parent form, and so it is transparent, but all the way to the parent form. So none of my controls show through the picturebox object.

Perhaps you can be more specific on what you have in mind to allow my picture box to be transparent?

thanks

To be honest I did it once right when I first tried C# out and then never used it after that. I don't know what you mean by a 50% transparent GIF. GIFs only have one channel for transparency meaning you assign a colour to them which is then transparent. Not a percentage based thing. So check your GIF.

Sorry I cannot be of much more help.

Would your client consider having the red circle X behind the form controls? i.e. As the background image of the frame? That would be much easier to do.

I am using Macromedia Fireworks. I draw my image, and I specify I want alpha transparency. When I draw a line, I set the opacity of the line to 50%. So what I should have said was opacity, not transparency.

I confirmed what I am seeing is that if I set the background color of the picture box to be transparent, then it shows through to the background of the parent form, in effect, blanking out the controls under the picture box so it looks like a "hole" in the form so you see the form background color where the transparent picturebox is located. It is almost what I want, but I need to have the controls be visible.

I was thinking as well that I could make the background color be red or some other "special" color so you can tell something is different about the dialog when it is up.

Hi , i need to make an app that reads emails in a specific mailbox
and extract some xml at the bottom of the mail...

what would be the best way to do this?

I have these pieces of code:

public class MyClass : System.Net.Sockets.TcpClient
//
// ...
//
public MyClass ()
		{
			MyProperty = new TcpClient ();
		}
//
// ...
//
public TcpClient MyProperty {
			get { return MyProperty; }

			set { MyProperty = value; }
		}

And when I execute the following line of code I get a StackOverflow:

private MyClass myNewClass = new MyClass ();

If I step through the execution, the program continually calls the set method of MyProperty until the StackOverflow occurs. Any help as to why this is occuring and how to fix it would be very appreciated.

Thanks!

Think about it. Your class has a property named MyProperty. In the constructor, you set the value of that property. But the property setter recursively calls itself ("MyProperty = value;"). Instead, you need to declare a private variable _MyProperty, change the setter to "_MyProperty = value;" and the getter to "return _MyProperty;".

Or better yet...adhere to the design guidelines and do myProperty rather than _MyProperty. Smile | :)

A+=1 is the equivelant of A=A+1 so I would say A*=3 is the same as A=A*3. I hope that refreshes you!

There is an Int32.Parse(string) function, but it will throw an exception if the string is not an integer.

Serialization Question

Marcus Spitzmiller24-Feb-03 7:38

Marcus Spitzmiller

24-Feb-03 7:38

Here's the deal - I have two programs. One is a utility program used to create objects and serialize them to disk. The second program is the real application which, in time, will be able to deserialize these objects and use them.

When I serialize and deserialize within the utility program, I have no problems. However, when I try to deserialize within the main program, I get an error that looks like:

"Type is not resolved for member MyNameSpace.MyClass, MyNameSpace."

I was getting a different error earlier, but I was able to make it further by setting the assembly names to be the same in each program. Is that necesarry and the correct thing to do?

Storing code, roughly:

<br />
Stream myStream = File.OpenWrite(m_sFileName);<br />
if (myStream != null)<br />
{<br />
  BinaryFormatter formatter = new BinaryFormatter();<br />
  formatter.Serialize(myStream, m_object);<br />
}<br />

Loading code for both programs, roughly:

<br />
if (myStream != null)<br />
{<br />
  BinaryFormatter formatter = new BinaryFormatter();<br />
  m_object = (MyObject)formatter.Deserialize(myStream);<br />
  myStream.Close();<br />
}<br />

Any help is appreciated!

Try to use the Binder property of the formatter. This interface can be used to search for types of different assemblies. Another solution is to put all the assemblies in the GAC.

Davide - I managed to work this out. Thanks for the help, but it turns out that I'm just not very familiar with the IDE yet. I had some references messed up, and once I straightened it out, it serialized with no problems, and no customizations.

Thanks again
