Re: [Lazarus] Remote application
I understand that there are (at least) two ways to do the remote display. A) Read the pixels from the graphics driver. This is what VNC does. The problem here is, that you don't know when an update is necessary (and thus you need to do polling) and that reading the pixels needs a lot of performances (get a GDI-handle, read the complete screen memory via the bus and then transfer only the pixels that have changed). (In fact some time ago I stole this code from VNC, translated it from C to Pascal and did a thingy that could transfer a rectangle of the screen via TCP to another PC.) or B) Hook into the interface between the application and the Windows manager. This is what Linux "Remote X" and Windows "Remote Desktop" do. VirtualBox (and supposedly VMWare) seems to be able to do do this, too, and here I did already see that it is possible to virtualize a single program rather than a complete Desktop. Seemingly NX can do both, depending on the situation. It's understandable that doing (B) is at least "difficult", when you want to attach to a running program, as supposedly a program transfers some information when starting and the Window manager needs to know same even when it requests a full repaint. But obviously Windows "Remote Desktop" can handle this problem decently. So attaching to an already running program (not the Desktop it runs on) using (B) is not that easy :-( . Maybe it's possible to something like starting another instance of the program with NX in the way you originally described and do some magic within the program itself to meld the running instance into the newly started one.

Re: [Lazarus] Indy & WinCE
Hi ALL. I got rid of the compilation problems of Indy. I've made a little test for WinCE and, good news, it works ! However some minor changes have to be made on a few units to have a clean compilation for WinCE: IdRegisterCore.pas, IdIMAP4.pas, idStackWindows.pas, IdWinsock2.pas Server: Vista32 Client; WinCE Compiled on Vista32, Lazarus 1.1 37816 (29/06/2012) indylaz.lpk compiled but not yet installed in the IDE Server uses a TIdTCPServer and connetions are handled within separated threads, one per new connection, as usual with Indy. Client uses a TIdTCPClient, connection is handled synchronously. Both client and server use the standard IoHandler Stream reader and writer and any binary data runs thru the streams without problem. Of course, I have to take care of string translations between Win32 (WIN1252 code page) and WinCE (Unicode) or whatever goes trhu (specifically from databases).

I suppose that NX not only compress, but decides from the server (in behalf the client application) what must be send to the client (the graphic server). A lot of things needn't to be send, a lot of things can be joint and send only the final result, and a lot of commands can be queued, cached and sent in less commadds. And the other way around, the client (the graphic server) needent to sent everything. I suppose that NX does smart decisions filtering what needs to be sent in both directions, so saves a lot of traffic and round trips. X11 It is acceptable when in a local machine, but not for remote machines, let alone a WAN. I've heard that the problem is in a poor use of X11 of libraries like gtk or qt, I've also heard that the problem is in xlib, the common libarry of most widgets that doesn't optimize the protocol. I have also heard that X11 is a too low level protocol and should be replaced. There have been some tries like http://en.wikipedia.org/wiki/Fresco_%28windowing_system%29. In fact, that is what javascript and ajax tries, send widgets etc. -- Saludos Santiago s...@ciberpiula.net -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Free Windows 8 OEM x64 for Lazarus Core Developer(s)
I'm looking to better Lazarus on Windows 8 (64bit). I realize it just came out and it may be not worth the time to run (even in a virtual-box). I'm offering a few Lazarus core developers a copy of windows 8 so they can have it to run and test and improve Lazarus. The only thing I want is 1: fcl-db components present (currently missing postgresql). 2: Install to Program Files and Build Projects. If the problem is out of scope - clearly identify problem areas and their external projects. Email me for acceptance, I will buy and drop-ship you the cd. You retain license for your time. Win8 Pro Upgrade or Win8 Pro Full.

dear colleagues: i have found how to fix the name of columns with the field´s name, and i have found how to fix the width of each colum. It works in a pretty way. as i have 20 fields with data about "projects", the last ones scroll the screen to the right and the PC´operator lost the project´s name and i am thinking to put and edit box in the upper place of the DBGrid to show the project´s name (one of the firsts fields of the record) for the active row. If i used a simple edit box, it can be programmed in the OnKeyPress Event, but I don´t know how to do it in the case of a dbGrid.
