Re: Passing a class by value, but reversed?

Can you make MyClass a struct? That way, it'll behave exactly as you want it to. The only other way is to clone the object, using MemberwiseClone or your custom deep cloning code.

programatically creating control instances

Pyro Joe24-Dec-05 15:51

Hi,
yeah I need to know how to create an instance of a control programatically. I know one can do soemthing like "TextBox tb = new TextBox();" but this has to be done in the initialization section fo the class, and if it's written within a method, it's only available for within that method. But this isn't the main problem, the main thing is that I don't necessarily know how many of a certain control will be needed, so how do I create new control on demand with a name either generated, or taken from user input via a textbox or something?
Thanks,
Stephen

This article doesn't work. I think something between vs '03 and vs '05 has changed. It wants me to create a ButtonArray, which does not exist. Here is what they have in the example:

// Declare a new ButtonArray object.<br />
ButtonArray MyControlArray;<br />
MyControlArray = new ButtonArray(this);<br />
// Call the AddNewButton method of MyControlArray.<br />
MyControlArray.AddNewButton();<br />

Well seeing how the ButtonArray thing doesn't exist, I can't really do anything with this. How do I go about creating control collections in visual studio 2005?

I don't get it, does your app run fine if you start it normally? I find it strange that you get a FileNotFoundException on the exact file that you're currently executing. Are you trying to launch it again from within the executable?

Getting .NET types programaticly?

mikker_12324-Dec-05 3:09

mikker_123

24-Dec-05 3:09

Is it possible to get .NET types using some C# code? For example:

<br />
		private void InitializeTypes()<br />
		{<br />
			cmbBlah.Items.Clear();<br />
<br />
foreach (NetType nt in GetNetTypes())<br />
			cmbBlah.Items.Add(nt.ToString());			<br />
		}<br />

?

tnx in advance

Re: Getting .NET types programaticly?

[Marc]24-Dec-05 4:19

The NetType you're talking about is actually System.Type[^] . You can get it using Object.GetType[^], Assembly.GetTypes[^] etc. For example, if you want to fill a combobox with all public types in your assembly, you can do:

using System.Reflection;

private void InitializeTypes(){
  cmbBlah.Items.Clear();

  // Get current assembly
  Assembly currentAss = Assembly.GetCurrentAssembly();
  // Get all public types from the assembly
  Type[] publicTypes = currentAss.GetExportedTypes();

  foreach (Type type in publicTypes){
    cmbBlah.Items.Add(type.ToString());
  }
}

Welcome to the wonderful world of reflection! Smile | :)

ASync Sockets Throwing Strange Exception

After a bunch of ASync socket calls, I get the exception below. Google-ing it came up with only 4 hits, 2 from the same person, none with answers.

This is happing in a server application, so if no one has a solution, is there another way to run a TCP server (average of 500 simultaneous, sustained connections. Max possible connections is about 5000, but VERY unlikely) without having a thread for each client, that would be great.

You must learn network programming for this.

Intentionally Slowing Down Program

Drausin23-Dec-05 11:01

23-Dec-05 11:01

I'm writing a program that does a lot of heavy computing. I eventually want this program to run as a screen saver. But because of all the heavy computer the program does, after a few minutes of running, the fan turns on - wasting energy and making noise, two things a screen saver shouldn't do.
So far I've tried various ways of putting the current thread to sleep for some time, to give the computer a rest, but I haven't had very much succes. Is there a better way to slow down my program or as least (safely) manage it so the fan doesn't come on?

Thanks,
Drausin

You could try modifying your process priority. I don't know if this will reduce the absolute processor load or if it's just relative to other processes...

Yea, I ended up doing that - putting a sleep function into my loop (as opposed to on a separate thread w/ a timer), and it seemed to work pretty well.

BinaryWriter is Not writing in Case of .sql files

VenkataRamana.Gali23-Dec-05 9:14

23-Dec-05 9:14

Hello all,

I am reading different types of files from DB & Storing at perticular place.

My code is as follows...

<br />
FileStream fs = new FileStream(sFileName, FileMode.Create, FileAccess.Write);<br />
BinaryWriter bw = new BinaryWriter(fs);<br />
				<br />
bw.Write(buffer);<br />
//Here buffer is byte[], this value getting properly<br />
bw.Flush();<br />
<br />
bw.Close();<br />
fs.Close();

This is code is not writing proper data only in case of .sql files

Why .sql not writing properly, anybody help me. If there is any alternate in C# inform me.

regards
GV Ramana
