Didn't you forget to pass a pParentWnd parameter to dialog constructor or Create function? If you omit it, the parent of dialog is set to main frame window.

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.

Can you provide a relevant code snippet (i.e., just the code necessary to recreate the problem)?

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....

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?

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.

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?
|
|
|
|
|
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.

Put the following in the dialog's OnInitDialog() method:
m_edit.SetEventMask(m_edit.GetEventMask() | ENM_CHANGE);

Hi!
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 ...

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.

Hai Friends,

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

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?

Sorry, yes you will definitely need the platform SDK.
