Yes, but if you wrote that program in C++, it would have been a lot more work. And if your program was a lot more complex, your installer would still be 300MB. There's no way around that.

I'm sorry, I can't make head or tails of this. However, while the framework is pretty bloated, I can see how Microsoft wouldn't bother with the work to break it into sections. Otherwise, when another .NET app tries to run on this computer, instead of checking if 3.5 is installed, it would need to work out if it had all the parts needed. And from the point of view of Microsoft, they just want the whole framework to be out there, anyhow.

Your installer, including the framework, will fit on a CD. Most people have internet bandwidth to download it if they don't have it, you can write an installer that downloads it if needed, so not everyone has to download it. It's not complicated, and it's pretty self evident if you think about it. Microsoft has nothing to gain in complicating the process by breaking up the framework for your convenience.

thanks alot.

my problem was actually about the size of the package because I'm going to sell it online.
However, would u please give a suggestion about the kind of program that I can solve my problem. I have to convert it to any other languages. I can program with Java-C++-Delphi-.Net-VB and my project is graphical and is about catalog for any occupation.

thanks for ur replies...

Well, I'd just do an installer that doesn't include .NET, but downloads it if needed.

Well, if you are scared of the runtime, then you can use C++, and either use MFC and distribute that ( a lot smaller ), or just use the win32 API if you want REALLY small.

Most likely any one who would want to use your software already has .net; so don't worry about it.

On the download page (or whatever) simply state that the app requires .net x.y and let the potential user act as he chooses.

thanks for ur answer.

the main reason for my question was the size of .Net fw 3.5 package and I was looking for a way not to install that completely and I didn't get any appropriate way.

If you are talking about Exchange server there is a web service of Exchange 2007 sp2,
if you are talking about pop3 mail server you can try connecting to server by simulating telnet from your application and delete mail.

System.Threading.Thread.Sleep(_TimeOut);
return Login(username, password);

khosnur1-Sep-09 21:21

1-Sep-09 21:21

thanks again for reply..
here is the method:

private MAIL_ERROR SendCommandSynchronous(string cmd, out string response, bool bMultiLineResponse)
{

// Remove any data that was left over on the buffer
string deadData = _conn.Receive();
_conn.Send(cmd);

response = WaitForResponse(bMultiLineResponse);
return MAIL_ERROR.ERROR_NONE;
}

private string WaitForResponse(bool bMultiLine)
{
int timeout = 5000; // wait 10 seconds for response

int waitedTime = 0;
string strRet = "";
while (waitedTime < timeout)
{
System.Threading.Thread.Sleep(_TimeOut);
strRet += _conn.Receive();

if (CommandComplete(strRet, bMultiLine) == true)
{
return strRet;
}
waitedTime += _TimeOut;

}
return strRet;
}

Tamer Oz1-Sep-09 21:44

Could you try

private string GetResponse()
{

    //read till finding new line, return.

    string strPrev = null;

    string strCurrent = null;

    string strMessage = null;

    NetworkStream ns = default(NetworkStream);

    ns = client.GetStream;//Previously instanced and connected TcpClient

    while (true)
    {

        byte[] buffer = new byte[1];
        //read by 1 byte 1 byte

        ns.Read(buffer, 0, buffer.Length);

        strCurrent = System.Text.Encoding.GetEncoding(1254).GetString(buffer);

        strMessage = strMessage + strCurrent;

        if (strCurrent == @"\r" && strPrev == @"\n")
        {

            break; // TODO: might not be correct. Was : Exit While
        }


        strPrev = strCurrent;
    }


    return strMessage;
}

private void SendMessage(string str)
{

    str = str + "\r\n";
    //Controlchars.CrLf '10+13

    byte[] buffer = System.Text.Encoding.GetEncoding(1254).GetBytes(str);

    NetworkStream ns = client.GetStream;


    ns.Write(buffer, 0, buffer.Length);
}

Hi everybody

I have a panel in my form, I used backgraound image for my panel.
In the Panel OnPaint event body, I draw ellipse with various position and dimension on each times.
So I use a timer, On the OnTimer event I Refresh panel for clearing previous ellipse and draw new ellipse with new parameters.

when form refreshed a bit jumping occurred in my background image, since I use mentioned operation every second, these jumping annoy the user.
I want to know how can disappear these jumping, Maybe for clearing prior ellipse use another method instead refresh or invalidate.

Best Regards,
Reza Shojaee

You can turn on double buffering.

this.SetStyle(
ControlStyles.AllPaintingInWmPaint |
ControlStyles.UserPaint |
ControlStyles.DoubleBuffer,true);

Please I would like your help in the following questions,(Please supply code example.)
:

1. How can I make a program’s able to link with its database independent of location?

There is a program I am trying to create. It works fine only if the database is placed in a particular location. I would like the program to be such that a user can install the program in any location and my program can look for and locate the database.

In a multi-tier network application, let us assume the following conditions exist:

• The front –end is in VB.NET/ C# .NET. (I am at home with any of them so you can write the code in any of these languages) The back-end is an oracle database.

2. How can I link the two? The front-end is not in the same computer as the database.

3. How can I make my apps able to read/ write real-time data?
Thank you .
