Hi,
I'm developing a C# application to process binary (b&w) images. I need to save them as PDF files.
I've found a few libraries (see example below) that would let me do so by saving the images as JPEG first and then converting them to PDF. Doing so however produces relatively large PDF files.
Example: http://www.codeproject.com/script/Forums/Edit.aspx?fid=1649&floc=/Forums/1649/Csharp.aspx
Any ideas on how I can directly convert System.Drawing.Image objects to B&W PDF files?
Thanks,
Sarab

With a library like the one you have. What do you think the image will be saved as, if not a JPEG ?

I'm writing an installer for a program that will be used on Vista. When I install the program for "all users", the data files for the program are stored in the virtual folder for each user, such as, "C:\Users\UserName\AppData\Local\VirtualStore\Program Files\MLW\MLW Program". When I uninstall my program, the data files in the virtual folders for each user are not automatically deleted. I need to add code into my program's Uninstall() method; however, I don't know how to do that for each user that isn't the current user.
Any help is appreciated.
Thank you,

I am developing program of C#,the windows are inherit from another library,such like the propty of the EnableBackgroundImage of buttons,it works well,but now I want to developing the multilanguage of the window,when I change the language of the window,some auto sources will be add to the designer.cs files,suck like "button.EnableBackgroundImage = null; " Is it the bug of the microsoft?is it because the project can not inherit propty of the EnableBackgroundImage well,and consider the EnableBackgroundImage is set nothing? 
when I change the language a part of designer.cs change to this ,its right
this.ocButton1.FKeyAllocation = Solno.OceanLibrary.Gui.FKeyAllocation.F1Key;
resources.ApplyResources(this, "$this");
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.FunctionID = "006MEF010";
this.Name = "PaMef01000";
this.OcFormHelpProvider.SetShowHelp(this, ((bool)(resources.GetObject("$this.ShowHelp"))));
this.SingleDisplay = true;
this.UseSecurity = true;
this.Load += new System.EventHandler(this.PaMef01000_Load);
this.FormClosed += new System.Windows.Forms.FormClosedEventHandler(this.PaMef01000_FormClosed);
this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.PaMef01000_FormClosing);
this.mainZone.ResumeLayout(false);
this.formZone.ResumeLayout(false);
this.baseZone.ResumeLayout(false);
this.buttonZone.ResumeLayout(false);
this.buttonZoneShift.ResumeLayout(false);
this.buttonZoneNormal.ResumeLayout(false);
this.ocPanel1.ResumeLayout(false);
this.ocPanel1.PerformLayout();
((System.ComponentModel.ISupportInitialize)(this.OcDataGridViewCassette)).EndInit();
this.ResumeLayout(false);
but when I change the text of button ,and save the windows ,designer.cs became this
this.ocButton1.AccessibleDescription = null;
this.ocButton1.AccessibleName = null;
resources.ApplyResources(this.ocButton1, "ocButton1");
this.ocButton1.BackgroundImage = null;
this.ocButton1.DisabledBackgroundImage = null;
this.ocButton1.EnabledBackgroundImage = null;
this.ocButton1.FKeyAllocation = Solno.OceanLibrary.Gui.FKeyAllocation.F1Key;
this.ocButton1.Font = null;
this.OcFormHelpProvider.SetHelpKeyword(this.ocButton1, null);
this.OcFormHelpProvider.SetHelpNavigator(this.ocButton1, ((System.Windows.Forms.HelpNavigator)(resources.GetObject("ocButton1.HelpNavigator"))));
this.OcFormHelpProvider.SetHelpString(this.ocButton1, null);
this.OcFormHelpProvider.SetShowHelp(this.ocButton1, ((bool)(resources.GetObject("ocButton1.ShowHelp"))));
this.OcFormToolTip.SetToolTip(this.ocButton1, resources.GetString("ocButton1.ToolTip"));
this.AccessibleDescription = null;
this.AccessibleName = null;
resources.ApplyResources(this, "$this");
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.BackgroundImage = null;
this.Font = null;
this.FunctionID = "006MEF010";
this.OcFormHelpProvider.SetHelpKeyword(this, null);
this.OcFormHelpProvider.SetHelpNavigator(this, ((System.Windows.Forms.HelpNavigator)(resources.GetObject("$this.HelpNavigator"))));
this.OcFormHelpProvider.SetHelpString(this, null);
this.Icon = null;
this.Name = "PaMef01000";
this.OcFormHelpProvider.SetShowHelp(this, ((bool)(resources.GetObject("$this.ShowHelp"))));
this.SingleDisplay = true;

this.Load += new System.EventHandler(this.PaMef01000_Load);
this.FormClosed += new System.Windows.Forms.FormClosedEventHandler(this.PaMef01000_FormClosed);

Hi,
AFAIK most network classes have a Close() method: Socket.Close, TcpClient.Close, UdpClient.Close, ...

My current code works fine, but I've encountered a problem. When a client connects to the TCP server, and they type a message it works the first time, but if its entered again, it just gives you the else. So lets say I typed shutdown in the client console. It would return Command Recieved, Initiating Shutdown. But if I try it again, it just gives me the else message. Its like its not cycling through the if statement again. What kind of code should I use to solve this issue?
Here is the code:
using System;
using System.Net;
using System.Net.Sockets;
using System.Text;
public class Server
{
public static void Main()
{
byte[] data = new byte[1024];
IPEndPoint ipep = new IPEndPoint(IPAddress.Any, 7557);
UdpClient newsock = new UdpClient(ipep);
Console.WriteLine("Waiting for a client...");
IPEndPoint sender = new IPEndPoint(IPAddress.Any, 0);
data = newsock.Receive(ref sender);
Console.WriteLine("Connection received from {0}", sender.ToString());
string welcome = "OpticVPS Remote Administration";
data = Encoding.ASCII.GetBytes(welcome);
newsock.Send(data, data.Length, sender);
while (true)
{
data = newsock.Receive(ref sender);
if (Encoding.ASCII.GetString(data, 0, data.Length) == "help")
{
string okay = "You can use the following commands";
Console.WriteLine("Help List Accessed By: {0}", sender.ToString());
data = Encoding.ASCII.GetBytes(okay);
newsock.Send(data, data.Length, sender);
}
else if (Encoding.ASCII.GetString(data, 0, data.Length) == "shutdown")
{
string shutdown = "Command Received, Shutting Down Now";
Console.WriteLine("Shutdown Issued - {0}", sender.ToString());
data = Encoding.ASCII.GetBytes(shutdown);
newsock.Send(data, data.Length, sender);
}
else
{
string err = "Command Not Found [End Of Line]";
Console.WriteLine("Command Error - {0}", sender.ToString());
data = Encoding.ASCII.GetBytes(err);
newsock.Send(data, data.Length, sender);
}
}
}
}

Well, if you want to use TCP connections, I'd start by using a TCP[^] client and a TCP[^] server. A UdpClient isn't going to help you very much.
In response to your other question about how to close a TCP connection, you should take a look at the Close()[^] method.

I have a project where I have a lot of panels on my form. It gets to be a hassel moving them front/back to edit them. Is there a way to encase the panel in a class, so I can just make it visible or invisible from class calls and not have to have it cluttering up my form during normal editing.
For example, I have a color picker panel which includes a listbox of all the color names and a picture box that I use to display the color and its name (using graphics). I can see where I could use this in several projects and don't want to have to recreate it everytime.
