An interesting question, indeed. I don't have a copy of the Standard with me to tell for sure. MSDN doesn't mention any such limit; they just say "a derived class can have a number of direct base classes"
My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.

Inorder to open the browser, we need to click on the Explorer icon.

Go to resource tab,and then click ICon.already there is MFC icon change what ever you want.u can made icon as u like.
|

|

What u answered is how to add an icon in VC++ program.
But what i want is an icon on desktop, clicking on which will execute a file.
For eg When click on notepad icon, notepad.exe will be executed.
In the same way i want my program to get executed when i click on the icon.
Anyhow thanks for ur reply.

What you want to do is to create a shortcut.
To do this, you need to know how to use COM, and a Windows shell interface IShellLink.
There is almost certainly an article on CP that shows how to do this, if you search on that keyword.

I think he is trying to disable one of the item among the whole.

yes that is what i want to do...
i read in google news groups that one suggested to put an Item Data that will notify if the item is disabled, and in the OnItemChanging return true to prevent the selection of the item if the item data flag is raised....
isn't there an easier way?
thanks

I don't have another suggestion yet... 
Or you can use any of the states like LVIS_CUT, etc. to do the same...
If you get a better method, please let me know too.

Oh! It is only a suggestion as I didn't try it yet.
I meant that if you are not using the states, for example LVIS_CUT state, it can be used as a disable item state.
So u can set the state of the item ( that you want to be disabled ) to the CUT state and in DrawItem you can check the state of each item and if it is in CUT state, you can draw it as disabled.

ok now i follow
but this is good only for the drawing, because i will still need to implement onitemchaning and prevent the selecting for that state....so it is just like puting an item data...
thanks

Hi,
I am facing problems in sending mouse clicks via SendInput API.
Mouse clicks are being sent but at the X,Y co-ordinates.
I am mapping my monitor to the (0,0,65535,65535) virtual monitor as needed by the SendInput. But the mouse clicks are always reported at the "current cursor location" (I am testing it with the notepad) irrespective of the X,Y co-ordinates specified.
Here is the code.
void SendMouseInput(unsigned int iX,unsigned int iY)
{
MOUSEINPUT mousei={0};
INPUT Input={0};
BlockInput(true);
::ZeroMemory(&Input,sizeof(INPUT));
::ZeroMemory(&mousei,sizeof(MOUSEINPUT));
mousei.dx=VirtualXFromAbsoluteX(iX);
mousei.dy=VirtualYFromAbsoluteY(iY);
mousei.dwFlags=MOUSEEVENTF_ABSOLUTE|MOUSEEVENTF_LEFTDOWN;
Input.type = INPUT_MOUSE;
Input.mi = mousei;
if(::SendInput(1,&Input,sizeof(Input))==0)
ShowError("SendMouseInput");
mousei.dwFlags=MOUSEEVENTF_ABSOLUTE|MOUSEEVENTF_LEFTUP;
Input.type = INPUT_MOUSE;
Input.mi = mousei;
if(::SendInput(1,&Input,sizeof(Input))==0)
ShowError("SendMouseInput");
BlockInput(false);
Sleep(1000);
}
static int VirtualXFromAbsoluteX ( int iX )
{
double Width = GetSystemMetrics ( SM_CXSCREEN ) ;
double Val = ( ((double)iX/Width) * (double)(65535) ) ;
double Ceil = ceil ( Val ) ;
double Floor = floor ( Val ) ;
if ( Ceil > Floor )
{
iX = (int)Ceil ;
}
else
{
iX = (int)Floor ;
}
return ( iX ) ;
}
static int VirtualYFromAbsoluteY ( int iY )
{
double Height = GetSystemMetrics ( SM_CYSCREEN ) ;
double Val = ( ((double)iY/Height) * (double)(65535) ) ;
double Ceil = ceil ( Val ) ;
double Floor = floor ( Val ) ;
if ( Ceil > Floor )
{
iY = (int)Ceil ;
}
else
{
iY = (int)Floor ;
}
return ( iY ) ;
}
void ShowError(LPTSTR lpszFunction)
{
TCHAR szBuf[80];
LPVOID lpMsgBuf;
DWORD dw = GetLastError();
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM,
NULL,
dw,
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf,
0, NULL );
wsprintf(szBuf,
"%s failed with error %d: %s",
lpszFunction, dw, lpMsgBuf);
::MessageBox(NULL, szBuf, "Error", MB_OK);
LocalFree(lpMsgBuf);
}
Am I doing something wrong?
PS: I am able to send key board events using SendInput.
Thanks a load in advance.

Hi Subra,
Try debugging the code by putting a break point over the event.

I tried all possible debugging.
The data is going to SendInput correctly.
But the click is happening at the point where my mouse pointer is currently pointing. I also set windows hooks to monitor the mouse events before any application gets its hands on it. There also I see that the x,y co-ordinates are coming wrongly.

Function();
{...
m_nftp.MoveFile("/"+NameSelected,"C:\\"+NameSelected,
FALSE,TRUE);
m_nftp.LogOffServer();
//SetFileName(Filetitle,path+filetitle)
theApp.m_pWinamp->SetFileName(NameSelected,
"C:\\"+NameSelected);
theApp.m_pWinamp->Wload(); //Load WinAmp's playlist
My problem is that Winamp cant load the life altought (after manually i can add it )(file not corrupted)
Is a way to delay so Winamp can load its Playlist ?

iam not getting any error wnen the same code in SwitchView(CString str)
fn is written in on OnCreateClient(.....) but it getting error it is written in SwitchView.where switch view is a fn called when a tree item is clicked
*********Heere i want to get a spiltter when an event is arised send me a gud solution.***********
...............sahaja

In case of the code in OnCreateClient(...) it is working because the splitter window is created there for the first time.
But if you want to change the view in the splitter window at runtime then you have to follow different procedure. Its not just simple delete one view and create another.;P
