Re: Unicode + console app + cout Daniel Lohmann17-Jul-02 13:58 Daniel Lohmann 17-Jul-02 13:58  You have to use the wide character version (wcout) to print unicode strings. However, I have noticed that internally everything is just converted to ANSI before the buffer is put out (via WriteFile() ) to the console. So if you are using "fancy" charsets this may fail -- Daniel Lohmann http://www.losoft.de Title Bar Font?

I suppose they got the HWND and did some thing under it. I tried and successful added my text in the TrayClock. but the problem is how can I fix the width of trayclock? its width is related with left side iconbar. I want the changing of trayclock can automatically affect on iconbar even TrayNotify(the parent form of trayclock). how to get it? Question about sequence of events ns17-Jul-02 8:12 ns 17-Jul-02 8:12  I want my app to show up blank if there is no database name in the registry, but popup a CFileDialog OPen. I query the registry in oninitialupdate of the view, and at the very last statement, if there was no dbname in the regsitry I sendmessage to trigger the "Open Database" menu item. When the app runs, (no dbname in regsitry), the first thing that pops up is the OPen dlg, not my blank view!!!! I tried sending the msg in a function calledin oninitial update - same result. How can I get my blank view to show up first, with the CFileDialog Open dlg over it? If I dont send the msg, and exit the oninitial update I get the UI as expected. But then where would I send the message? I am quite puzzled. Any suggestions?

I think I've initialized the buffer, but why i can have this strange result after i put 'X' in the first character of buffer. Thank you!!!!! Re: string initialization problem Joaquín M López Muñoz17-Jul-02 8:16 Joaquín M López Muñoz 17-Jul-02 8:16  buffer[0] = 'X'; This sentence owerwrites the previous value of buffer[0], which was the terminating null character from strcpy(buffer, "");As you haven't added any additional terminating character, the remains of the first string appears, hence the output. To get the result you're after, write: buffer[0] = 'X'; buffer[1]=0; Unless you're doing this for fun or learning purposes, it is strongly advisable that you leave this char manipulation stuff in favor of more robust alternatives like std::string.

Therefore passing in an empty string copies zero (0) characters and leaves the string untouched. If you want the string to be only 'X' you need to do something like: buffer[0] = 'X'; buffer[1] = '\0'; The second character is the null character (the slash means it is an escape character); which in C means the end of the string. Character strings in C are always string length + 1. Example: The string literal, "Hello World!", is actually 13 characters long, the 12 visible characters plus 1 for the null.

So far when you've run there has been a null anyway but at some point you could end up with a string several MB long ! We've all done it when starting out. Elaine (Trollslayer) NT Service networking Greven17-Jul-02 8:01 Greven 17-Jul-02 8:01  I'm beginning work on an NT service (only in the early design phase right now) that will need to respond to network requests. I've done work with networking before, but this will be my first service. What I'm finding already is that there doesn't seem to be an easy way to handle networking. At least not as intuitive as through CSocket with MFC. What type of system does everyone else use for a service? I know I can setup a thread that continually tries to receive, and that might work. I've also looked into using the MFC service classes out there (PJ Naughter's in particular) so that I can use CSocket again. Both seem to have there up's and down's. Is there an easy way that I'm not seeing? Also, as a second question. How do you control a service? I understand how to start, stop, and pause them. But how do I grab it and call a function? Or can I? Basically, if I write a control panel applet for example, how do I adjust the service in realtime? I could always write adjustments to the registry, but then I would also have to have a thread watching for changes and that doesn't seem very logical either. Again, is there an easy way that I'm just not seeing? "Go Confidently in the direction of your dreams. Live the life you've imagined." - Thoreau Re: NT Service networking Daniel Lohmann17-Jul-02 14:09 Daniel Lohmann 17-Jul-02 14:09  To write your very first service is always a bit of hard work. However, it is not that difficult as it looks like: 1) To really work with a service you need some kind of inter-process-communication (IPC). IPC is the way to communicate with your service. Sockets are one example for IPC, I usually prefer NamedPipes or RPC (because they integrate well into the NT security modell), but one may also use shared memory, sockets, NetBIOS and so on. 2) Even if possible I recommend not using MFC in a service. For things like CString or CArray it is you can use the ATL/WTL classes that provide a compatible interface. Or use STL. Especially CSocket is a no-no. It is integreated to much into "windowing applications". 3) To control a service a CPL or MMC snap-in is a really good solution. You can monitor the registry as you suggested, but you could also inform the service about changes via a Win32 event object, IPC or a user defined service control code. The last one is elegant because you don't need an own watcher thread. 4) Debugging a service is a bit hard, because it is not possible to run it directly under the debugger. However, you could connect your debugger later on to the service (via task manager). To debug service startup code a hardcoded breakpoint works best. // some code _asm int 3 // Program will break here // some more code If the code reaches the hardcoded breakpoint, the usual "unhandled exception" dialog box will appear and give you the chance to attach the debugger.

The last one is elegant because you don't need an own watcher thread. What exactly do you mean by this? What is a user defined service control code? Also, if I do use normal socket code, is it common to have a looping thread that just sits there waiting to receive something? Programming in binary is as easy as 01 10 11.

Using the ControlService() API you can send control codes to a services' handler function. Besides the predefined control codes (SERVICE_CONTROL_STOP, SERVICE_CONTROL_PAUSE, etc.) the range 128-255 is reserbed for user-defined control codes. Greven wrote: Also, if I do use normal socket code, is it common to have a looping thread that just sits there waiting to receive something? Yes, there must be some thead that waits for recieving something. However, you could use overlapped IO so the thread is not blocked and can do also something else. You could even use the services' main thread for that purpose (the thread that starts in your ServiceMain). -- Daniel Lohmann http://www.losoft.de disable keys in word document Srini Kella17-Jul-02 7:38 Srini Kella 17-Jul-02 7:38  My web project allows a user to navigate to a word document.
