TOXCCT alias Nicolas C. crc checksum program for cd johnjsm28-Jan-04 2:42 johnjsm 28-Jan-04 2:42  Can anyone help me to start off a crc checksum program that will check entire cd's or dvd Re: crc checksum program for cd Roger Wright28-Jan-04 3:33 Roger Wright 28-Jan-04 3:33  There's a dandy CRC-32 article here[^]. Heard in Bullhead City - "You haven't lost your girl - you've just lost your turn..." [sigh] So true... I just have problem to open inside !!! Mehdi_Hosseinpour28-Jan-04 2:40 Mehdi_Hosseinpour 28-Jan-04 2:40  I use a dialog box to open wave file. The full path of file will be copy to a char* variable 'pInputFileName' by CFile::GetFilePath and a variable 'pInside = "..\in.wave" but when i use CFile f; fin.Open(....) and finput.Open(...) a problem will create one file will open not two file. The full path name of file that will be opened by CFile has "\" Not "\\". If you write this will see my problem. Thank you. Mehdi Hosseinpour Re: I just have problem to open inside !!! David Crow28-Jan-04 2:44 David Crow 28-Jan-04 2:44  Can you provide a relevant code snippet (i.e., just the code necessary to recreate the problem)? A rich person is not the one who has the most, but the one that needs the least. Re: I just have problem to open inside !!! toxcct28-Jan-04 2:52 toxcct 28-Jan-04 2:52  it's hard to understand everything... anyway, we're here on an "international" site, that's powerful to progress, isn't it? i'd like to know why you don't try to open your file basically by streams, with <font style="color:blue;">#include</font> <iostream> ? There are so many operations you can do like this, it would probably be more simple for you.... TOXCCT alias Nicolas C. emulating a hard disk Möhre28-Jan-04 2:40 Möhre 28-Jan-04 2:40  Has somebody an idea how to make a "virual hard disk"? The disk needn't be readable. I yast want to be notified when a new file is created (or moved) in it. At the moment I mounted a directory to a hard disk ("subst y: C:\temp") and catch the notifiction on this folder via FindFirstChangeNotification, FindNextChangeNotification, ... Maybe someone know how to do this with a device driver? Tanx Möhre Re: emulating a hard disk Diddy28-Jan-04 4:13 Diddy 28-Jan-04 4:13  If you want a 'real' disk, then yes, you are into device driver land. You could just the DefineDosDevice function to define a disk from a folder (thats how subst.exe does it), and then use QueryDosDevice to find out what the folder that drive maps to is . So say if you had drive y: substed to C:\temp, at the moment you are telling findfirstchangenotifaction to watch C:\temp, you could use QueryDosDevice to programmatically find out which folder y: maps to, so you would have somthing like: FindFirstChangeNotification(MapDriveToFolder("Y:"), ....) where MapDriveToFolder is a helper function that calls QueryDosDevice and returns the folder the drive maps to. Re: emulating a hard disk Möhre29-Jan-04 2:01 Möhre 29-Jan-04 2:01  Thaks, seems to work! By the way: is it possible to subst an allocated memory to a DOS-Disk, so i don't need the folder? Re: emulating a hard disk Diddy29-Jan-04 3:50 Diddy 29-Jan-04 3:50  No problem In regard to the second bit - not easially no. DefineDosDevice basically creates a symbolic link to a real device (which may just be a folder on the haddrive in the case of subst). The symbolic link is then seen as a new drive. I don't belive you can link to a chunk of memory without a custom driver which implmements a device that just reads and writes to that memory - and if your doing one of them you may as well just do a disk driver anyway and forget symbolic links. How to male some window - be over some other windows ? vgrigor28-Jan-04 2:11 vgrigor 28-Jan-04 2:11  I created one window, and that second as a Pop-up.

I am trying to integrate the DHTML editing control to a win32 dialog. For that I manually copy-pasted the code (CONTROL IDC_DHTML ....) from a mfc application resource to my win32 api application resource and I import the dhtmled.ocx. The program doesnt open when I click on it ( it also doesnt give an error message). Am I doing something wrong? Well... I am a beginner ... Re: Win32 - ActiveX question Mike Dimmick28-Jan-04 2:30 Mike Dimmick 28-Jan-04 2:30  MFC does a lot of work behind the scenes to pretend that you can place an ActiveX control in your resources and have it 'just work'. See the code in DLGCORE.CPP in the MFC source, particularly CDialog::CreateDlgIndirect, for more details. The Win32 dialog box API knows nothing of ActiveX controls and bombs out because it cannot find a suitable window class for the ActiveX control. If you want to host ActiveX controls in a raw Win32 application, you need to implement a control site (from memory, you need to at least implement the IOleContainer and IOleControlSite interfaces) and then create the controls yourself. For anyone who cares, MFC preprocesses the dialog template before passing it to Windows, stripping out (but remembering) any ActiveX control data and any list box initialisations (Win32 doesn't do this either). When Windows sends WM_INITDIALOG to the window, MFC actually calls CDialog::HandleInitDialog, which creates any ActiveX controls, initialises them, and performs any other control initialisations, before calling your override of OnInitDialog. In this way, it presents the illusion that ActiveX controls are controls like any other.

Plase anyone give me a step by step procedure Re: IP Address SJolly28-Jan-04 1:51 SJolly 28-Jan-04 1:51  Hello, I've done this before using windows sockets. I don't know if it's the best way, but it definitely works: char szHostName[400]; struct hostent *hostinfo = NULL; IN_ADDR addr; char szIP[16]; // "xxx.xxx.xxx.xxx\0" ULONG ulIP = 0; // get the dns name as a string gethostname(szHostName, 400); // get the host info (contains ip address) hostinfo = gethostbyname(szHostName); if(hostinfo == NULL) { DWORD dwError = WSAGetLastError(); // handle the error } else { // get the ip as ULONG ulIP = *reinterpret_cast<pulong>(hostinfo->h_addr_list[0]); // put the ip it into an IN_ADDR addr.S_un.S_addr = ulIP; // changes ip into string sprintf(szIP, "%s", inet_ntoa(addr)); TRACE("My IP address is %s\n", szIP); } Regards, Simon Re: IP Address Anonymous29-Jan-04 0:24 Anonymous 29-Jan-04 0:24  Hai, Thanks for your message. But when i copy the given code lot of errors occured. IN_ADDR undeclared identifier etc. I have not insatlled Platform SDK. For running the code may i need the Paltform SDK? regards Anish Re: IP Address SJolly29-Jan-04 0:40 SJolly 29-Jan-04 0:40  Sorry, yes you will definitely need the platform SDK.
