My project requires to change Default Web Site of IIS to other name (example: medi) for browse http://medi instead of http://localhost. I don't know how to code in C#. Please give me a clue to solve.
Thanks.

Perhaps you can add the domain in the host file if you only want the name on your local machine.
If it is a network wide setting, you have to do it in your dns settings.

Hi,
Recently I have been working on creating an ActiveX DLL (for performing Image Scan using TWAIN and C#) which could be invoked using a Javascript call from an HTML page and the scanned image could be displayed within the page. I got most of the things but when I invoke the TWAIN driver, it displays the scanning control, I can perform New Scan multiple times within it but when I click at Accept nothing happens, the same code works perfectly when I invoke it from a Windows Form.
I trapped Windows Messages, it seems that when I do a call to the ActiveX from HTML it does not send any message back when I click Accept in the Scanning control.
The code for using TWAIN scanning using C# writtem by NETMaster was the guide for my current activity.
Help would be highly appreciated.
Regards,

Hi,
I developed P2P file transfers application using C#.NET in PC its working fine , but in Windows Mobile 5.0 , the chunks downloading is not complete, after downloading 4 or 5 chunks(32kB), its stopping.How to speed up the application?..
Anybody have idea?please help me..

Hi Sri harini,
being a bit more specific would be helpful. What kind of protocol are you using (TCP or UDP)? How do you buffer the chunks? How does it stop, with an exception? Maybe you should also post relevant parts of your code.
Regards
Sebastian

Hi Sebastian
We are using the following code to Read data,using TCP protocol.How to set the receive timeout option in Windows Mobile.Bcoz its throwing exception when we use SetSocketOption Method.
Please advise.
public void ReadData()
{
Byte[] buffer=null;
Socket s=null;
int port = threadVars.port;
int chunksize=threadVars.chunksize;
int cid = threadVars.cid;
int fileid = threadVars.fileid;
string hash = threadVars.chnkhash;
readlocked = false;
s=new Socket( SocketAddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
s.Bind(new IPEndPoint(IPAddr, port));
s.Listen(1);
Socket actualReader = s.Accept();
NetworkStream DataStream = new NetworkStream(actualReader);
int offset = 0;
int bytesActuallyRead = 0;
int i=0;
do
{
i = i++;
bytesActuallyRead = DataStream.Read(buffer, offset, buffer.Length - offset);
offset += bytesActuallyRead;
if (bytesActuallyRead == 0)
{
break;
}
Thread.Sleep(10);
}
while(actualReader.Connected && i<1000);
parentController.SocketReadComplete(false,cid, fileid, buffer,chunksize,hash);
}
DataStream.Flush();
DataStream.Close();
s.Close();
}
Thanks
Sri harini

Hi,
I have devolped one .net application using c#.net, according to my application requirement it should run only in 1024*768 resolution..
so, how can i get the resolution for a particular machine and change it to my desired resolution?
is that possible?
Jaydeep

for getting current resolution of system u can use
Screen.PrimaryScreen.Bounds.Height;
Screen.PrimaryScreen.Bounds.Width;
to change the resolution of system there is no direct way u have to use some window API's
rahul

It is generally bad practice to change the resolution on your users' machines. However, here is a good article about how to do it in C#:
Using P/Invoke to Call Unmanaged APIs from Your Managed Classes[^]
See the section: Task 2: Changing the Display Resolution

Use overload of Process.Start that takes an arguments parameter.

Change the main method of application to Main(String[] args). args will conatin the passed command line parameters.

Are you using the Enable Visual Styles in your application?
[STAThread]<br />
static void Main() <br />
{<br />
Application.EnableVisualStyles();<br />
Application.Run(new Form1());<br />
}

to remove. go to publishing Designer selects the form and change the property ControlBox to false.
to intercept.
public const int WM_SYSCOMMAND = 0x0112;
public const int SC_CLOSE = 0xF060;
protected override void WndProc(ref Message m)
{
if( m.Msg == WM_SYSCOMMAND)
{
if( (int) m.WParam.ToInt32() == SC_CLOSE )
{
if (ProjectIsOpen)
{
return;
}
else
{
this.Close();
Application.Exit();
}
}
}
base.WndProc (ref m);
}

hi,
first thanks for your reply. second i want to ask you a more detailed question. what if i want to hide only the close button and the maximize button and keep the minimize button. The property ControlBox when set to false hides the three buttons together even if i try to set the maximizebox to true it want appear.
i hope u have a solution for that.

try it.
private const int SC_CLOSE = 0xF060;
private const int SC_MAXIMIZE = 0xF030;
private const int SC_MINIMIZE = 0xF020;
private const int SC_RESTORE = 0xF120;
private const int MF_GRAYED = 0x1;
[System.Runtime.InteropServices.DllImport("user32.dll")]
private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert);
[System.Runtime.InteropServices.DllImport("user32.dll")]
private static extern int EnableMenuItem(IntPtr hMenu, int wIDEnableItem, int wEnable);
private void Disable_opt()
{
EnableMenuItem(GetSystemMenu(this.Handle, false), SC_CLOSE, MF_GRAYED);
EnableMenuItem(GetSystemMenu(this.Handle, false), SC_MAXIMIZE, MF_GRAYED);
EnableMenuItem(GetSystemMenu(this.Handle, false), SC_MINIMIZE, MF_GRAYED);
EnableMenuItem(GetSystemMenu(this.Handle, false), SC_RESTORE, MF_GRAYED);
}

Perhaps you should ask this in the C forum instead.
