Hi,
I am working on an application which enumerates the shares from a remote computer and open it in explorer.
I have successfully got the names of the shares and now I am trying to open a directory lets say //station1/eBooks on the remote station1.
The behavior would be the same as typing //station1/eBooks on Run in Start Menu Or any other share scaner like shed. I have tried a new process for "explorer.exe" and passing the path as argument. It works fine for local shares but access denied instead of giving the login prompt for remote folders.
Anyone knows how to do it Plz reply. Thanks in advance.

I think you should do something liek this:
file://username:password@your/path
but I am not shure
Q:What does the derived class in C# tell to it's parent?

Accessing the path via .NET does not prompt for credentials. This is a function of the shell. .NET is not the shell. If you want to prompt for credentials, catch the exception, prompt for their username and password, and then impersonate the user and try reconnecting. For more information on impersonating a set of credentials, see the class documentation fo the WindowsImpersonationContext in the .NET Framework SDK, which also includes an example.

Thanks for your reply.
Let me restate by problem. I enumerate the shares, user doulbe click on the share in the list view, the share is opened in the explorer (if password is required windows asks for it itself). Its the same behaviour like lan netscan or any other share scan software.
Plz take a look at shed. Its a realy small software but great speed. Download link is below.

Sorry, I didn't quite understand you before. Take a look at System.Diagnostics.Process. You could invoke Windows Explorer on the share like so:
string path = "share path";
Process.Start("explorer.exe", string.Concat("/e,", path));You can find more about the Windows Explorer command line switches at http://support.microsoft.com/default.aspx?scid=kb;en-us;130510[^].

Alright, anyone knows how to put a ProgressBar as one of the panels in a StatusBar?

Yes. First, make sure that StatusBar.ShowPanels is true, and add your panels. To make things easier, make your panel that will host the ProgressBar fixed-width (this is common in most apps beside).
Next, handle the StatusBar.DrawItem event. Your event handler should look something like the following (assume statusBar1 is your StatusBar, and progressBar1 is your ProgressBar):
private void statusBar1_DrawItem(object sender, StatusBarDrawItemEventArgs e)
{
Rectangle bounds = e.Bounds;
bounds.Y = statusBar1.Top + SystemInformation.Border3DSize.Height;
bounds.Height += SystemInformation.BorderSize.Height * 2;
bounds.X -= SystemInformation.BorderSize.Width;
if (statusBar1.SizingGrip && ((Form)statusBar1.Parent).WindowState ==
FormWindowState.Maximized)
bounds.Width += SystemInformation.VerificationScrollBarWidth;
progressBar1.Bounds = bounds;
}This works, though there might be more elegant solutions you could search for.

If a shorter code means elegant, perhaps this is one.  Btw, thanks again.
private void statusBarBrowser_DrawItem(object sender, System.Windows.Forms.StatusBarDrawItemEventArgs sbdevent)
{
if(sbdevent.Panel == statusBarPanelProgress)
{
Rectangle rectPanel = sbdevent.Bounds;
rectPanel.Y += statusBarBrowser.Location.Y;
progressBarBrowser.Bounds = rectPanel;
}
}

The reason some of that code was there because the code you have above won't draw quite right in the bounds specified by the StatusBarPanel, especially if you need to take a sizing grip into account.

I see... I have disabled the sizing grip.

Why don't you tell us what the SecurityException read? There's many reasons that can be thrown.

The exception i got is -->
System.Security.SecurityException.
Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level.

I think u can creat a panel and dock it a side first. Then put your buttons into it.

Hi All!!!

Can soemone help?
Thanx in advance

Almost all the controls in System.Windows.Forms encapsulate their Windows common controls equivalents. Not all of these controls support all the notification messages that raise events in .NET. The ComboBox, for instance, pops up and hides its scrolling popup window used for the drop down on WM_LBUTTONDOWN and is not double-click aware. If you want to make it so, you're going to have to extend the ComboBox controls in .NET, override WndProc, and handle many of these messages yourself. To handle messages like WM_LBUTTONDOWN though, you might have to use an IMessageFilter.
Anyway, you'll have to capture this message before it goes to the base class's WndProc method (which you should call base.WndProc(ref m) after your code) and start a timer. If the timer elapses, call SendMessage (which you'll also have to P/Invoke) with the original data that came with the WM_LBUTTONDOWN message. If the user clicks again before the timer elapses, then you've got your double-click event and should throw-out the WM_LBUTTONDOWN message (i.e., don't send it). The easiest way to raise this event is to just call base.OnDoubleClick, which will raise the DoubleClick event.

I need to be able to turn off the screensaver or disable it some how while my app is running. You see, I developed a Media Player, so the screensaver should not be able to take over while watching a longer video.
Does anybody knows how to...??

You'll need to P/Invoke the SystemParametersInfo API like so:
[DllImport("user32.dll")]
private static extern bool SystemParametersInfo
(
[MarshalAs(UnmanagedType.U4)] int action,
[MarshalAs(UnmanagedType.U4)] int param,
IntPtr data,
[MarshalAs(UnmanagedType.U4)] int winini
)
private const int SPI_SETSCREENSAVEACTIVE = 0x0011;When you call this, you'll want to make sure that you activate it again, so you'll want to design your code something kind of like this:
try
{
SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, 0, null, 0);
}
finally
{
SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, 1, null, 0);
}Optionally throw a catch in there if you want, but make sure you use a finally block or some other means of re-activating the screensaver in case of success OR failure (if possible). The calls above also do not update the user profile, so this change will not persist after a reboot (which seems to be the way you'd want it for what you're doing).

Hello, Im new to all this. I was looking for an algorithm that display the sin function graphic. Can you help me please?
Thanks

Gosh! This is going back a bit... I haven't worked with trig' functions since I was a developer on a team building a GIS product.
double y;
for(double x= 0.0; x=< (Math.PI*2.0); x+=0.01)
{
y = Math.Sin(x);
}
This will generate the coorinates for one cycle.
