Subclassing Problem Dennis L28-Jan-04 5:55 Dennis L 28-Jan-04 5:55  Hi All! I have subclass an edit control and all works fine. The problem is when the compiling ends I have two warnings: warning C4312: 'type cast' : conversion from 'LONG' to 'WNDPROC' of greater size. warning C4311: 'type cast' : pointer truncation from 'LRESULT (__stdcall *)(HWND,UINT,WPARAM,LPARAM)' to 'LONG'. These warnings are from this code: OldEditControl = (WNDPROC)SetWindowLong(GetDlgItem(hwnd, IDC_NUM), GWL_WNDPROC, (LONG)EditProc); The strange is that on Win98 I don't have these warnings. I have them on WinXP What's wrong? Not receiving Registered Broadcast Message Member 81460328-Jan-04 5:49 Member 814603 28-Jan-04 5:49  I am using MSVC++ 6.0 and MFC. I need to send message between two applications. I've registered a message via RegisterWindowMessage using the same string in two separate applications. The message has been sent with ::SendMessage(HWND_BROADCAST . . . and BroadcastSystemMessage, but the secnod application is not seeing the message. I can see that the message was sent by watching with Spy++. I have attempted to watch for the message both through the messaging macro ON_REGISTERED_MESSAGE and by overriding the PreTranslateMessage method on both my view and application classes in the intended recipient. Can anyone see what I'm doing wrong? Re: Not receiving Registered Broadcast Message Diddy28-Jan-04 11:15 Diddy 28-Jan-04 11:15  HWND_BROADCAST broadcasts messages to toplevel windows only, where are you trying to handle the message? MFC doesn't route non command messages, so if you have a MFC app you will have to catch it in the frame window and not in the doc/view/app etc, then manually route it to the doc/view/app if you wan't to process the message there.

TCHAR buffer size TomD228-Jan-04 5:48 TomD2 28-Jan-04 5:48  Is there a reason why the maximum buffer size for a TCHAR seems to be 121 WideChars (for me at least)? Is there a way to increase this size? Cheers. Re: TCHAR buffer size Michael P Butler28-Jan-04 5:51 Michael P Butler 28-Jan-04 5:51  How are you allocating your buffer? Michael But you know when the truth is told, That you can get what you want or you can just get old, Your're going to kick off before you even get halfway through. When will you realise... Vienna waits for you? - "The Stranger," Billy Joel Re: TCHAR buffer size TomD228-Jan-04 6:05 TomD2 28-Jan-04 6:05  I'm declaring this: _TCHAR temp[4000]; and then using it in a call to this: int len2 = (int)strlen((char*)testLine)+1; MultiByteToWideChar( CP_UTF8, 0, (char*)testLine, len2, (_TCHAR*)temp, 4000); I've also tried to concat TCHAR onto TCHAR using pointers, but again it stops working when it reaches a size of 121 WideChars. Thanks for your time, Tom. Re: TCHAR buffer size Michael P Butler28-Jan-04 6:17 Michael P Butler 28-Jan-04 6:17  Does testLine have any /0 characters in it? How is testLine defined is it a char[]? I assume your app is being complied as _UNICODE?

Vienna waits for you? - "The Stranger," Billy Joel Re: TCHAR buffer size TomD228-Jan-04 6:35 TomD2 28-Jan-04 6:35  Does testLine have any /0 characters in it? No (unfortunately). How is testLine defined is it a char[]? char testLine[2000]; I assume your app is being complied as _UNICODE? It is indeed..... Cheers, Tom. Re: TCHAR buffer size Anonymous28-Jan-04 7:53 Anonymous 28-Jan-04 7:53  If you've defined _UNICODE why don't you just use TCHAR's instead of mixing TCHAR's with char's and use the generic text mapping routines (_tcslen() instead of strlen()). If the _UNICODE identifier is found _tcslen() will resolve to wcslen() otherwise it's strlen(). Instead of using MultiByteToWideChar try using mbstowcs() it's simpler. Re: TCHAR buffer size TomD228-Jan-04 21:21 TomD2 28-Jan-04 21:21  Originally I did just that, using all TCHAR's. Unfortunately, it again hit the buffer size of 121 and stopped concatonating. It concats the whole lot in char's no problem, so I changed to this tactic and then tried to convert - same problem. Buttons with alternative message satcat28-Jan-04 5:45 satcat 28-Jan-04 5:45  Hi! Could I show an alternative message when I move the mouse over a button in my Visual C++ application (in a little floating yellow window)? How could I do it? Thank you in advance I have no idea Re: Buttons with alternative message valikac28-Jan-04 7:54 valikac 28-Jan-04 7:54  Interesting. Try deriving a class from CButton and handle the mouse move message. If it is within the button control's rectangle, then show the message. Kuphryn Re: Buttons with alternative message satcat28-Jan-04 8:01 satcat 28-Jan-04 8:01  Do you know how could I show a message in this way? I don't have idea about this. Thank you!

See MSDN for detailed description Handling Close View event CodeBrain28-Jan-04 4:59 CodeBrain 28-Jan-04 4:59  I am searching for a good way to inform an object which paints into a CView window if the user tries to close the view. It's very important for me that my paint object first stops its painting and then do an deinitialization before the view can be closed. So I must catch the close event, send an information to the paint object and then send the close message again to the view. Any good ideas? Thanks in advance. Re: Handling Close View event basementman28-Jan-04 10:02 basementman 28-Jan-04 10:02  Try adding a handler for OnDestroy() to your view. Call your deinit routine, and then call the base class CView::OnDestroy().  onwards and upwards...  Please HELP ME!!! How to get rights accesses of a shared folder programmatically? bouli28-Jan-04 4:57 bouli 28-Jan-04 4:57  Hi gurus, All resides in this simple question: How to get rights accesses of a shared folder programmatically? I tried the NetShare* API but the permission value of the PSHARE_INFO_502 structure is not supported on WinXP/2003 (it is said in the doc of the structure). MSDN says to use Authorization API. Can anyone show me how to retrieve this information? I tried AccessCheck, but it seems complex to initialize. From a network shared folder, I simply want to check if I can read or write on this shared folder. Please help! Thanks! Draw Circle in Shell with Char ? Eldalie28-Jan-04 4:27 Eldalie 28-Jan-04 4:27  Hi everybody, Has anyone ever suceeded in drawing a Circle in C++; in the Shell Command with characters like '*' ? I tried a few combinations but the best alternative I have developed a Circle in form of a pentagon, but is it possible to draw a 360 degree Circle in the Shell Command ? best regards Tolga Re: Draw Circle in Shell with Char ? Anonymous28-Jan-04 4:32 Anonymous 28-Jan-04 4:32  Its the resolution that is your problem, drawing a perfect circle with carrots or periods would be difficult unless you could make it big enough. For an example of what I'm talking about, go into paint and make a circle, then zoom into it, and you'll see how the pixels are arranged to create the illusion of the circle to the human eye. Hope it helps. ~Tony
