The problem is that your service is running in an elevated security context, while the user's desktop is not. Putting a window on the user's desktop exposes the service (running elevated) to interaction with the user's programs (non-elevated). That's why Vista and Win7 put service displays on a separate desktop, and ask the user to switch to it. Note that having interactive services is strongly discouraged, the current implementation is a compatibility measure. If you want to display stuff on the workstation, your service can do the following: 1) use WTSSendmessage for simple dialog boxes. 2) Create a new process from the service (with CreateProcessAsUser). Use the credentials of the currently logged on user (note that there may be more than one user: fast user switching may be active)

Hi, This approach won't work as calling Response.Write will force the Response Headers to be sent to the client. To get the AJAX style loading screen I think you're trying to get, you should include the markup for the busy icon on the first page and call the StartShowWait() method on the button click. The CSV will then generate as a normal ASP.Net request as you'd expect. Regards, Martin

I know the feeling - I've still got a little more work to do on my MIDI wrapper, and most of the implementation has come from studying the relevant C header file rather than relying on stuff on PInvoke.net (which can be useful, but occaisionally just plain wrong) etc. It made my brain hurt - lots, which is why it's not finished yet!

1. There are several third party frameworks bringing webdav-apis for .net 2. ???? AFAIK WebDav is a protocol for file-operations over web. How should this work together with remoting? 3.

I guess your problem is the replacement of linefeeds and newlines with an incompatible alternative. You know, just like you have to choose "ASCII-Transfer" in your FTP-Tool so that notepad.exe can show the config-files of your linux-server correctly. You need to preserve the whitespace. Try reading binary, replacing a single letter, then writing the otherwise unchanges binary result back to a new file. You have reached your goal as soon as the two files afterwards are of the same size.

If the size is changing from 16k to 22k, you're doing a lot more than swapping a string! Just try with baby steps. Tweak one little bit, test, tweak a bigger bit, test, and so on. I've no idea about the format either - this is just general advice. It's worth jumping in the deep end sometimes, but other times you just dip one toe in the water. Iain.

So basically what you are doing has corrupted it. balu12345 wrote: it is not normal file,It is a file generated by PCL printer. Yes, so unless you know the format of the file you will mess it up. balu12345 wrote: I even cannot compare both file because the file is generated by PCL printer which has some non-readable data Ther eis no such thing as unreadable data. Use a hex editor to compare, there are plenty freely avalable. It does beg the question though, why do you have to change the PCL file rather than the original data.

You can try with this code.. [DllImport("user32.dll")] static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); //Or [DllImport("user32.dll", SetLastError = true)] static extern bool PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); //Or [DllImport("user32.dll")] static extern bool PostThreadMessage(uint idThread, uint Msg, UIntPtr wParam, IntPtr lParam); //Or [DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)] static extern bool SendMessageCallback(IntPtr hWnd, uint Msg, UIntPtr wParam, IntPtr lParam, SendMessageDelegate lpCallBack, UIntPtr dwData); //Or [DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)] static extern bool SendNotifyMessage(IntPtr hWnd, uint Msg, UIntPtr wParam, IntPtr lParam); //Or [DllImport("user32.dll")] private static extern IntPtr GetDesktopWindow(); //Or [DllImport("user32.dll", SetLastError = true)] static extern IntPtr FindWindow(string lpClassName, string lpWindowName); //Or [DllImport("user32.dll", SetLastError = true)] static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow); const int SC_MONITORPOWER = 0xF170; const int WM_SYSCOMMAND = 0x0112; const int MONITORON = -1; const int MONITOROFF = 2; const int MONITORSTANBY = 1; int HWND_BROADCAST = 0xffff; //the message is sent to all top-level windows in the system int HWND_TOPMOST = -1; int HWND_TOP = 0; // int HWND_BOTTOM = 1; //limited use int HWND_NOTOPMOST = -2; // Form frm = new Form(); Frm.Handle(); SendMessage(ValidHWND, WM_SYSCOMMAND, SC_MONITORPOWER, MONITOROFF ); SendMessage(ValidHWND, WM_SYSCOMMAND, SC_MONITORPOWER, MONITORON);

The code sample that is here on CP will work, but only for monitors that support it and only on the local machine. You'll have to write two applications to do this remotely. One app that runs, probably as a service, on each machine you want to control and one that sends the command to the service running on each machine.
