You only need a small amount of painted panels, as many as you can possibly see at any one time.
So you need to figure which pages are visible and generate those, not the invisible ones.
And you can destroy the ones that become invisible (due to scrolling in the document); or you could keep a small cache of say 10 panels, so scrolling back and forth goes a bit faster.

Hi,
I have a gridview and a panel. the data in the gridview are the links of the names. When i click any link of the row of that gridview, based on the program, it should show or hide the panel. But the problem is when i first click the link, panel is showing or hiding based on which link i clicked but when i click another link from the gridview, it is not executing its function. Any idea why is that?

Probably a bug. Can you post the relevant code?

+5, as it is the correct answer. As it reads, the user wants to put something in a UserControl.

You create usercontrols in the same way that you created the chat-controls.

class MyChattyControl: UserControl
{
public string ChatName { get; set; }
}
Location, height and width are already part of the UserControl, so you needn't implement them.

Hello,
i have the following code, which redirects the
output from a unmanged dll into a file:
[DllImport("Kernel32.dll", SetLastError = true) ]
public static extern int SetStdHandle(int device, IntPtr handle);
FileStream filestream;
StreamWriter streamwriter;
void Redirect()
{
int status;
IntPtr handle;
filestream = new FileStream("logfile.txt", FileMode.Create);
streamwriter = new StreamWriter(filestream);
streamwriter.AutoFlush = true;
Console.SetOut(streamwriter);
Console.SetError(streamwriter);
handle = filestream.Handle;
status = SetStdHandle(-11, handle); // set stdout
// Check status as needed
status = SetStdHandle(-12, handle); // set stderr
// Check status as needed
}
But I want to write the output to a winform-control
(textbox).
How can I do that?
Regards
Andreas

If the DLL's running in process, its console output should go to your stdout/stderr already. That means that you shouldn't need to explicitly redirect it with SetStdHandle; try removing that and see where its console output goes. (It should still go to the file through the redirected Console.SetXxx in your app.)
Then you need to create a wrapper for TextWriter that will give you write events; inheriting from StringWriter and overriding Write(char) should do it, but you might need to override Write(string) as well.
Pass an instance of this subclass to Console.SetOut/SetErr and hook up the event to write into your control.

Hello,
thanks for your anwer.
The dll is not running in process, the dll runs
in a another process.
The code works for me, but redirects only into a
file.
I tried out also "alternatives" to the filestream,
like memorymappedviewstream (MemoryMappedFile), get
the handle, but nothing works. 
Regards
Andreas

WCF- Service
CF binding is a set of binding elements and each element specify, how the service and client will communicates with each other's. Each binding must have at least one transport element and one message encoding element.
Different types of WCF bindings
WCF has a couple of built in bindings which are designed to fulfill some specific need. You can also define your own custom binding in WCF to fulfill your need. All built in bindings are defined in the System.ServiceModel Namespace. Here is the list of 10 built in bindings in WCF which we commonly used:
Basic binding
This binding is provided by the BasicHttpBinding class. It is designed to expose a WCF service as an ASMX web service, so that old clients (which are still using ASMX web service) can consume new service. By default, it uses Http protocol for transport and encodes the message in UTF - 8 text for-mat. You can also use Https with this binding.
Web binding
This binding is provided by the WebHttpBinding class. It is designed to expose WCF services as Http requests by using HTTP-GET, HTTP-POST. It is used with REST based services which may give output as an XML or JSON format. This is very much used with social networks for implementing a syndication feed.
Web Service (WS) binding
This binding is provided by the WSHttpBinding class. It is like as Basic binding and uses Http or Https protocols for transport. But this is designed to offer various WS - * specifications such as WS – Reliable Messaging, WS - Transactions, WS - Security and so on which are not supported by Basic binding.
wsHttpBinding= basicHttpBinding + WS-* specification
WS Dual binding
This binding is provided by the WsDualHttpBinding class. It is like as wsHttpBinding except it sup-ports bi-directional communication means both clients and services can send and receive messages.
TCP binding
This binding is provided by the NetTcpBinding class. It uses TCP protocol for communication be-tween two machines with in intranet (means same network). It encodes the message in binary format. This is faster and more reliable binding as compared to the Http protocol bindings. It is only used when communication is WCF - to – WCF means both client and service should have WCF.
IPC binding
This binding is provided by the NetNamedPipeBinding class. It uses named pipe for Communication between two services on the same machine. This is the most secure and fastest binding among all the bindings.
MSMQ binding
This binding is provided by the NetMsmqBinding class. It uses MSMQ for transport and offers sup-port to disconnected message queued. It provides solutions for disconnected scenarios in which service processes the message at a different time than the client send the messages.
Federated WS binding
This binding is provided by the WSFederationHttpBinding class. It is a specialized form of WS binding and provides support to federated security.
Peer Network binding
This binding is provided by the NetPeerTcpBinding class. It uses TCP protocol but uses peer net-working as transport. In this networking each machine (node) acts as a client and a server to the other nodes. This is used in the file sharing systems like torrent.
MSMQ Integration binding
This binding is provided by the MsmqIntegrationBinding class. This binding offers support to communicate with existing systems that communicate via MSMQ.

. Depending upon your requirements, you can choose a binding for your service as shown below in the diagram:

How to deal with the critical region in the programming language C #. Is there an example of this case or reference explaining that
|
|
|
|
|
|
|
The Thread class has a critical region method[^] that you could use.
There are other constructs like Mutex etc that could help you setup a critical region.

I'm trying to write a client for a webservice method, which responds with byte[]
I would like to stream it because byte[] will be failed if there is large file. I changed Transfer Mode and Encoding to Streamed and Mtom respectively. I commented XMLTypeAttribute declaration in reference file for the byte[] class. Please correct the code.
Reference.cs
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "2.0.50727.4016")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
public partial class echoBinaryDataResponse : object, System.ComponentModel.INotifyPropertyChanged {
private byte[] paramField;
[System.Xml.Serialization.XmlElementAttribute(DataType = "base64Binary", Order = 0)]
public byte[] param
{
get {
return this.paramField;
}
set {
this.paramField = value;
this.RaisePropertyChanged("param");
}
}
My client call
-----------
ServiceReference1.echoBinaryData echo = new ServiceReference1.echoBinaryData();
MemoryStream str = new MemoryStream(myByteArray);
echo.param = str;
ServiceReference1.echoBinaryDataResponse echoResp = new ServiceReference1.echoBinaryDataResponse();
ServiceReference1.SamplePortTypeClient sample = new ServiceReference1.SamplePortTypeClient();
sample.echoBinaryData(echo);-----getting exception here
Note: myByteArray is of type byte[];

What exception?

Sorry, forgot to add the exception
Exception:There was an error reflecting 'echoBinaryData'.
|

You need to trap this with your debugger or add some more code to identify the inner exception. "There was an error" tells us nothing.
