Please use code tags when posting code on daniweb:

[code]

...code here....

[/code]

Please go back and edit your last post, or post the error message again in code tags. I cannot read your post with the formatting the way it is.

Hello, there's a suggestion in error message:

Some errors can be fixed by rebuilding your project, while others may require code changes.

Have you tried rebuilding?

One more thing:

The type 'System.Windows.Forms.OpenFileDialog' has no field named 'file'.

Do you have such one? If no - remove the reference to it. Seems like the error lays somewhere near this field ..

Hello again and welcome to DaniWeb :)
Ok, let's start from error, that you get:

"Unable to cast object of type 'CSocketPacket1' to type 'CSocketPacket'."

I'm not sure if I'm right .. depends on what is CSocketPacket1 . Looks like a typo :) If it's not - is there any relationship between CSocketPacket1 and CSocketPacket (I mean inheritance)? If not - C# doesn't support implicit conversion from user-defined types to pre-defined types.

And regarding this:

im developing a Lan chatting System...
i wnt to recieve data and accept at the same page....
its working only ig there is only two systems... 1 server n anthr 1 as client.....

Could you provide more information about problem you're facing .. and maybe some code, that gives errors or is incorrect?
