Yo hey what's up?
I was skimmin over some of the asynchronous socket examples on MSDN and happened to notice all the call backs were static.
I am not to familar on how this IAsyncResult stuff works but from what I understand they work on another thread receiving data from a client as one example. If a server is receiving data from 2 clients and the everything is already hooked up aka meaning all the call backs.
client1.BeginReceive(state.buffer,0,StateObject.buffersize,0,new AsyncCallback(ReadCallback),state);
client2.BeginReceive(state.buffer,0,StateObject.buffersize,0,new AsyncCallback(ReadCallback),state);
and ReadCallback is static then the are sharing the same instance of it.
But if the instance is already doing work ie. receiving data from one client.
How can it recieve data from another client.
I guess what I am saying is how can 2 threads share one instance of a method.
Thanks for any help or insight on this...

The "ReadCallBack" funtion seems to act as a recursive function (anyways from the examples I have seen) running till done, and normally recursive functions are static in nature (and good in design IMO).

HI,
Good Morning.
I would be very glad if any of you can help me out of this. I'm a beginner in C# and I've to do this for my project.
I have an MDI form which in turn consists of some SDI form. One of them is a Windows form developed in C#, which consists of some controls like Command Buttons. Another SDI form is a Flash file (.swf). Now I've to establish communication between these two. For example, if I clik on a command button, I've to animate the .swf file, which involves transfer of some data. This is the beginning of the process and still needs to be enhanced.
If any of you need any clarification on this, please mail me to vas@aim.co.kr.
Thanks and Regards.
Srinivas Kadiyala.

The only way to do that is via XML I would think. That and obviously using the Flash activeX control.

Hi,
Thanx a lot for the reply.
Now I would something like this :
Suppose I would press a command button in the form. Then it would change the value of a variable and put it in XML. Then I would retrieve the value from the XML and pass it on to the Flash ActiveX control and do some animation in the .swf file and vice versa.
Is it OK? Is this possible? Can you suggest some enhancements to this design? Please give your valueble feedback since I'm new to both .NET and Flash.
Sorry for the trouble.
Cheers...

Hello All,
I am getting frustrated now....
How do I store cursors and retrive them from a .NET assembly dll?
The resource file support does not seems to extend to cursors. I am
building components not an application and wish to add several cursors
to the component or resource only dll.
Any help?
Best regards,
Paul.
Jesus Christ is LOVE! Please tell somebody.

What are trying to do? You can serialize it...If its a struct, then you Marshal it and read the bytes...

well it could be a struct, it could be a class, or it could be a string. the infor has to be made into a byte[] so it can be sent off through a socket.

Then Serialize it thru the BinaryFormatter. Your class will need the Serializable attribute.

Hi All,
I'm having a problem with the width of the columns in a datagrid. How do I get the columns in a datagrid to "auto expand" to the width of the data in the columns? I've messed around with the PreferredColumnWidth property, but it doesn't give the right results.
Any Ideas?

I tried to remove scrollbars of a MDI parent form by setting AutoScroll to false. However when a MDI child form is outside the range of MDI parent form. The scrollbars is appeared again. As a result, I can't find a way to design an MDI parent form as EXCEL. Can someone kindly give me an idea of this problem? I will appreciate very much.

I am afraid this behaviour is by design.

Thank you for your kind reply.
I really appreciate for your prompt reply.
I just wonder how Microsoft can write an program like EXCEL.
In Excel, they also use MDI method to design their program; however I didn't see the scrollbars when the MDI child is over the range of a MDI parent form.
Is there really noway to solve this problem? Or can I use any WIN32 API to get rid of the auto scrollbars of MDI parent form?

Unfortunately no. Although you can get the window handle of the MDI container, and call an interop WIN32 function to change the window style and by the way remove the scrollbar(s), the fact is those are going to be back soon automatically because that's what the implementation of the Form class does (actually most of the layout logic is implemented there and in the ScrollableControl class it derives from).
I am afraid that if you want such thing in your app you have to write your own MDI container. Interesting topic by the way, and source code you can ultimately share with us!
Hint : derive your class from System.Windows.Forms.Control, instead of System.Windows.Forms.Form.
PS : Unlike what you say, I don't know what might be wrong with a scrollbar displayed as soon as a MDI client goes off the client area. That's safe, and it allows to reach it. Without a scrollbar, how would you get it back ?

Thank you for your reply.
Actually, the reason for me to design such a MDI form without scrollbars is that it really doesn't look good when I first first load 2 of my MDI child forms into my MDI parent form. I tried to fit those two MDI child forms vertically and each of them occupies half height of the range of MDI parent form; however scrollbars came out and destroy the outlook of my program. I think you are right about having scrollbars is safe. I know it could be hard and difficult to accomplish this task. I just hope to find out the easy way for me to do this.
PS: I really appreciate your prompt reply. I might try what you suggested me to do.

I have to disagree, scrollbars don't need to show because of that. Why don't you tile the MDI clients instead vertically or horizontally ? Get yourself the Scribble sample (MSDEV.NET CDs), I am pretty sure you'll like it.

Thank you for your reply again.
Here is the information related to this issue that I got from GotDotNet Community. You might want to know.
[Quote Begin]
Sorry to say but this is a bug in the 1.0 version of the framework. I 've already posted this same question in 3 different forums here on gotdotnet but no one could help or figure it out.

http://www.gotdotnet.com/Community/MessageBoard/Thread.aspx?id=20185&Page=1#20270
I finally used one of my support credits and called microsoft. It took them about 3 weeks to figure out that this was a bug in the framework. It has nothing to do with VB, C# or any other language. They said they would put the request in to fix this in the next release. I havent checked 1.1 to see if its fixed but that may solve your problem. If you're already using 1.1 then you might have to wait for the next release.
Cheers,
Reginald

what is the best way to save variables (login ID, etc) accross all forms without killing the PC memroy and application performance?

Those things are unrelated to each other. Serializing one or more objects can be directed to flat files (see BinaryFormatter for instance), with no memory overhead.
Application performance ? Of course, if you are supposed to serialize 10000 object states 10 times each second, you are likely to have a couple issues, but isn't it up to you to write an appropriate application logic instead ? For instance, why the states of all objects should be saved if the last state has really changed for only a fraction of them.
