Hello once again frends!
Well right now im stuck doing a web form...well its actually finished though the only problem i have left is how i can print my form without showing my dropdown lists and buttons.
I've come up with something though im not realy sure how to go about this. the plan is upon firing my print button (which i havnt made yet) i put the entire html into a variable (easy enough) then pass that variable into a similar page except without the dropdown lists and buttons(fairly easy)...though retreival of the html is a b*tch. quite frankly...how do i do that? is it even posible?
Sori im in such a haste...though all your post will be much appreciated.
Thanx all!

Interesting that to print your are essentially re-running the HTML through your own print logic. I'd have to agree that would be ugly but more importantly is it what you really want or do you want a screen capture of the Client Window?
The latter is pretty simple Win32 type stuff, get the application form device context: Left, Right, and size coordinates. Use a GDI calls like GetRegionData, SaveDC, etc to snatch the image, then you can either save and print or just render the image to the printer. It's probably a tad more work but at least you can design a generic screen grab and print class that you could reuse. A cool application that I have used for years is SnagIT, which does what I'm talking about but it also saves the image to your favorite file format (BMP, GIF, JPEG, etc.) Depending on how far you wished to take this you could build a mini-SnagIT for your application library.

My apologies for the very late reply i was on a short weekend vacation. About ur post...nice logic i thought about saving it though i havnt the sense to think it through. Then it occured to me, im not the one who will use this form its the other department (meaning computer iliterate, lazy management ). So basicaly i have to create a print function that directly prints out the form with those preferences without having to save and/or edit it. Is there posibly a way?
By the way thanks so much for reply!

hello,
i'm interested in how to get the windows color theme. i'm developing a small programm, where i need to draw my own forms. i overrided the onpaint method and the drawing works fine so far. i now want to draw some form colors depending on the actual windows colors (like the standard blue, green or silver).
does anyone know, how i can get information about this setting in c#?
best regards
pikebu

SystemColors and SystemBrushes may be of some use, you may also want to search for uxtheme if you want to draw themed elements.

i am doing here some some socket-client work in C# windows service
it is working fine for multiple clientss
now i want to limit these multiple clients to 25 for example
i want that when service starts objects for all these 25 clients
are created and when client connects it should be accepted and will not allow more than 25 clients to connect
and when client diconnects that object can be allocated to another client who requests
i am not able to make up logic how i will first create 25 objects and store them in array
and how i will be checking wether object is free or not to be allocated to another client
code:
protected override void OnStart(string[] args)
{
// TODO: Add code here to start your service.
listen obj;
Thread threadlisten=null;
obj=new listen();
threadlisten =new Thread(new ThreadStart(obj.startlisten));
threadlisten.Start();
}
in listen class listen.cs
public class listen
{
TcpListener server=null;
Thread tcpthread=null;
client cl=null;
public listen()
{
//
// TODO: Add constructor logic here
//
}
public void startlisten()
{
Int32 port = 3310;
IPAddress localAddr = IPAddress.Parse("192.168.0.5");
// TcpListener server = new TcpListener(port);
server = new TcpListener(localAddr, port);
// Start listening for client requests.
server.Start();
// Enter the listening loop.
while(true)
{
// Perform a blocking call to accept requests.
// You could also user server.AcceptSocket() here.
cl= new client(server.AcceptTcpClient());
tcpthread=new Thread(new ThreadStart(cl.getClient));
tcpthread.Start();
}
}
public void stoplisten()
{
server.Stop();
}
}
in client class client.cs
public class client
{
TcpClient tcpClient;
// Buffer for reading data
Byte[] bytes = new Byte[256];
String data = null;
public client(TcpClient Client)
{
//
// TODO: Add constructor logic here
tcpClient =Client;
}
public void getClient()
{
try
{
data = null;
// Get a stream object for reading and writing
NetworkStream stream = tcpClient.GetStream();
int i;
// Loop to receive all the data sent by the client.
while((i = stream.Read(bytes, 0, bytes.Length))!=0)
{
// Translate data bytes to a ASCII string.
data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
// Process the data sent by the client.
string replyMsg = data;
clamdCommand x=new clamdCommand();
replyMsg=x.Command(replyMsg);
byte[] msg = System.Text.Encoding.ASCII.GetBytes(replyMsg);
// Send back a response.
stream.Write(msg, 0, msg.Length);
//Console.WriteLine(String.Format("Sent: {0}", data));
}
}
catch(Exception se)
{
}
// Shutdown and end connection
tcpClient.Close();
}
}

All you gotta do is have an IF statement check the number of clients. Now would I recommend hardcoding 25.... nope. Read the restriction quantity from a config file. That way you can change the number of supported clients without recompiling the code. Your app would read in the parameter at startup and pass it to the listen class. The you would have something like:
class listen<br />
{<br />
.<br />
.<br />
.<br />
<br />
uint mClientCount = 0;<br />
uint mClientLimit = 0;
.<br />
.<br />
.<br />
<br />
public listen(uint limit)<br />
{<br />
mClientLimit = limit;
}<br />
<br />
public void startListen()<br />
{<br />
.<br />
.<br />
.<br />
if (mClientCount < mClientLimit)<br />
{<br />
cl= new client(server.AcceptTcpClient());<br />
tcpthread=new Thread(new ThreadStart(cl.getClient));<br />
tcpthread.Start();<br />
++mClientCount; <br />
}<br />
.<br />
.<br />
.<br />
<br />
}<br />
Note: make sure you decrement mClientCount in your Disconnect logic so that you counter stays accurate. Since you are using threads, you will have to manage the synchronized access to the
client counter. You can use lock {} or use a Mutex, or AutoResetEvent depending on your preference and performance needs.
Good luck!

is it possible for string type constants to be declared in interfaces in C#.net?how to implement interfaces use these constants in other classes

Hi goodmorning,
yaa it doesn't work in interfaces
Sridevi

I wrote this in interface
public interface Style
{
static const string STYLEFREEFORM = "STYLE_FREEFORM";
Error:Interfaces can't contain fields
so how to define constants?,i want to implement these are other classes..any suggestions..give me small example for this context

Why don't you use a namespace as the logical container for the interface and any constants you want to declare?

Rob Philpott.

Plz give me example

IIRC Clarity. All consts are treated statically, and if there were consts and static consts there would be people confused about the difference (none) between them.

isn't that methods rather than members? Without checking the books I wouldn't have thought you could have any members in an interface. I presume we consider members and fields are the same thing in this context..

Hi Goodmorning,
yaaa in this context members & fields are same..

First, make sure you're in the right forum (C# programming language).
There are lots of articles on the web as well as several open source search libraries that might help you out if you study them. One that comes to mind is Lucene (and the .NET port, DotLucene).

Hi!
I am developing a software using c# for windows platform, and i need to know if there is any possibility of knowing when a system or user process is invoked that is before it's execution.
I will be very grateful for any help.
take care
