Re: bind and port numbers Le centriste2-Dec-02 7:40 Le centriste 2-Dec-02 7:40  I think that no more than one application can bind to a given port at the same time. Michel It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to. - TreeBeard Re: bind and port numbers Dave_2-Dec-02 7:56 Dave_ 2-Dec-02 7:56  Thanks, since the port number is 0 here, doesn't that mean that it will attempt recv. from all port numbers?

Hm... have you tried using port 0? You can't bind to port 0! Rickard Andersson@Suza Computing C# and C++ programmer from SWEDEN!

Re: bind and port numbers Dave_2-Dec-02 8:24 Dave_ 2-Dec-02 8:24  Yes, I have tried - we have software that has been running for years this way. The problem came up when another application sent/rcvd UDP messages at the same time. I'm guessing that they are using the bind with port 0 also (for the rcv socket), and they are getting some of the UDP messages that were meant for us. Re: bind and port numbers Rickard Andersson202-Dec-02 8:34 Rickard Andersson20 2-Dec-02 8:34  Aah.. but then it must be specific for the UDP protocol to bind on port 0! I don't know UDP that much.

Re: bind and port numbers Dave_2-Dec-02 8:38 Dave_ 2-Dec-02 8:38  Thanks anyway. Maybe I will post another message with UDP and port 0 in the heading. This is very difficult to find any information on since 90% of programmers are using TCP instead.

Re: bind and port numbers carrie2-Dec-02 11:30 carrie 2-Dec-02 11:30  as far as I know, trying to bind to port 0 using UDP will just make it pick its own port that isn't already allocated. You can't have 2 programs running using the same port. http://www.ecst.csuchico.edu/~beej/guide/net/html/syscalls.html Its for linux but its the same case as far as I've tested (lots in the last month) as winsock. I've just finished a biggie UDP based program and wouldn't let it try to bind to port 0 if my life depended on it, I'd rather know where it was going thanks recursively search the registry and delete text Derek Smigelski2-Dec-02 7:04 Derek Smigelski 2-Dec-02 7:04  I need some help. I need source code that will recursively search the registry and delete text found. It would need to work on 95/98/NT/XP/2000. I'm looking to return a list (perhaps in a list box) of all keys (ALL TEXT) that were found. If that Text appears anywhere in registry I want it added to my list. Then I can select/deselect what I wish and then delete the selected items. Allow someone to highlight and delete specific ones. Any ideas? Any help is appreciated. Cheers, Derek Re: recursively search the registry and delete text Joan M2-Dec-02 9:11 Joan M 2-Dec-02 9:11  try this: HKEY hKey = NULL; CString csCadenaA[10]; CString csCadenaB[10]; csCadenaA[0] = "Software\\akuna\\matata\\"; csCadenaB[0] = "LionKing"; csCadenaA[1] = "Software\\lilo\\stitch\\"; csCadenaB[1] = "ls"; for (int i=0;i<10;i++) { RegOpenKeyEx(HKEY_LOCAL_MACHINE,csCadenaA[i],0,KEY_ALL_ACCESS,&hKey); if (hKey != NULL) { RegDeleteKey(hKey, csCadenaB[i]); } } OK, the strings used in this sample are stupid, but it works... Hope this helps... File extension and default icon act_x2-Dec-02 6:51 act_x 2-Dec-02 6:51  How do I specify an Icon and a default File Extension to my MDI document ? Please help Re: File extension and default icon Rickard Andersson202-Dec-02 7:32 Rickard Andersson20 2-Dec-02 7:32  You can specify an extension in the wizard when you create your MDI project. The Icon can you just replace, that one you have as standard can you find in the res directory I think. Just replace the icon and TADA!

Re: File extension and default icon Nitron2-Dec-02 10:08 Nitron 2-Dec-02 10:08  In your string table, you will find an entry for IDR_xxxxxxTYPE, where xxxxxx is your original file type. Replace the text in the string to: \nJunk\nJunk\nJunk Files (*.junk)\n.junk\nJunk.Document\nJunk Document Where Junk is your document type. Hope that helps. - Nitron "Those that say a task is impossible shouldn't interrupt the ones who are doing it." - Chinese Proverb WM_SYSCOMMAND Jamie Hale2-Dec-02 6:14 Jamie Hale 2-Dec-02 6:14  Am I missing something? If I want to hook the minimize button, I add an OnSysCommand() method and look for SC_MINIMIZE, right? What would make my CPropertySheet-derived dialog behave differently? I get the SC_CLOSE, but no SC_MINIMIZE. J May the bear never have cause to eat you. Re: WM_SYSCOMMAND Jamie Hale2-Dec-02 11:38 Jamie Hale 2-Dec-02 11:38  No no, don't everybody rush to help out. It turns out that you need to specify the WS_MINIMIZEBOX when you actually create the CPropertySheet-derived window (ie, pDlg->Create(whatever, WS_OVERLAPPEDWINDOW); // <- included in there). Specifying it later did not seem to work. And using ModifyStyle() in the InitDialog() showed the minimize box, but wouldn't actually allow the dialog to send the associated WM_SYSCOMMAND. Weird. I lurve MFC. J May the bear never have cause to eat you. Re: WM_SYSCOMMAND Paul M Watt3-Dec-02 8:14 Paul M Watt 3-Dec-02 8:14  That kind of jogs my memory. I am not sure if this is what you were experiencing, but you need to make a call like this: ::SetWindowPos(hWnd, NULL, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE | nFlags); after certain style changes with SetWindowLong in order for the style to be completely set into the window. Maybe the WS_MINIMIZEBOX is one of those styles. Build a man a fire, and he will be warm for a day Light a man on fire, and he will be warm for the rest of his life! Re: WM_SYSCOMMAND Jamie Hale3-Dec-02 9:34 Jamie Hale 3-Dec-02 9:34  Hmmmm. I did a quick check it didn't succeed, but that doesn't mean much. Thanks for the pointer - it's a useful tidbit to know regardless of whether or not it solves this problem. J May the bear never have cause to eat you. Windows hook luftwaffe2-Dec-02 5:44 luftwaffe 2-Dec-02 5:44  Hello, I am looking for the mentioned sysmsg.dll . I was unable to find on my Windows 2000 and it is not included with Visual Studio (I have a service pack 5). Could you please help me (let me know) where could I get it? Or is there somebody who has it (perhaps with a lib and header if required) and could send it to me? Thanks CSpinButtonCtrl as an In-place control cgreathouse2-Dec-02 5:11 cgreathouse 2-Dec-02 5:11  I'm currently building a ListView control that is able to be edited in-place. So far I've got an edit control working, but I'm having problems with a spinner control. The first problem is I can't set the focus to the spinner control after I've created it. I tried using the same method (SetFocus()) I used for the edit control but doesn't work. The second problem is I can't trap when the 'Esc' or 'Enter' are pressed. For the edit control I'm using PreTranslateMessage(), but it's not getting called when the spinner is created. Anybody no what's going on? Have an examples I can take a look at?
