The error means what it says. Can you read ? You can use ToString() if you want to convert the type to a string.

Image objects to PDF files

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 ?

Vista file virtualization: Deleting files when uninstalling program

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,

is it bug of the microsoft?(about multilanguage) [modified]

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? Frown | :(

when I change the language a part of designer.cs change to this ,its right

//
// ocButton1
//
this.ocButton1.FKeyAllocation = Solno.OceanLibrary.Gui.FKeyAllocation.F1Key;


//
// PaMef01000
//
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.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

//
// ocButton1
//
this.ocButton1.AccessibleDescription = null;
this.ocButton1.AccessibleName = null;
resources.ApplyResources(this.ocButton1, "ocButton1");

this.OcFormHelpProvider.SetHelpString(this.ocButton1, null);

Hi,

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

C# TCP Cycle

Serpendiem1-Jun-09 12:42

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:

public class Server
{

        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";  //where?
        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";

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.
