Hello,
i use other funktion to delete all objects befor closing dialog, looks something like this:
POSITION pos = cMap.GetStartPosition();
CString csKey;
CMyObject* cMyObject;
while(NULL != pos)
{
CMyObject* myOb;
cMap.GetNextAssoc(pos, csKey, (CObject*&)cMyObject);
delete cMyObject;
cMap.RemoveKey(csKey);
}
i dont know what else to do! 
Question is on witch place to set use "delete"? I need all data during program run, only solution is
before closing the dialog??
regards

I dont see any memory leak, if you are using above code.

Are you asking this ?
you can write it in DestroyWindow(). Provided cMap is dialog class member.

You're creating new objects when you add them to the map, but you're never deleting them
Either:
1) At the end, go though the elements of cMap, and delete everything
2) Use smart pointers, that'll delete the objects for you

Hi everyone,
i had a component with diff PopUp Buttons, to catch the OnClick-Event i added a message-handler in the
Pane ( it herids from CWnd ) and a click on the different PopUp Buttons executes the code in the method On_xxxxxx_Click() in this Pane.
Now, i have created a modified the component and added a Click-Handle that determinates the Button of the component who's clicked.
Then i must send a message to the Pane to execute the On_xxxxxx_Click() ( The Pane doesn't change )
void MyTaskPanel::OnLButtonDown(UINT nFlags,CPoint point)<br />
{<br />
<br />
TaskPanelGroup* Item;<br />
<br />
Item = HitTestGroup(point);<br />
<br />
UINT SelectedID;<br />
if(Item) {<br />
SelectedID = Item->GetID();
SendMessage(BN_CLICKED,(WPARAM)SelectedID,NULL);
} else {<br />
}<br />
}
In the pane i have this message-map :
BEGIN_MESSAGE_MAP(Home_Bht_Kunden_Side, CPaneView)<br />
ON_BN_CLICKED(ID_OF_CLICKED_BUTTON,On_ID_OF_CLICKED_BUTTON_Click)<br />
...<br />
END_MESSAGE_MAP()<br />
<br />
void ThePane::On_ID_OF_CLICKED_BUTTON_Click()<br />
{<br />
int test = 9;
}<br />
<br />
The Question: If i send a message from out the component, where does the message arrives?
Can all Message-Maps receive this Message and trade it ( if it matches )
Big Thanks

BN_CLICKED is not a message, it is notification code and should be sent through WM_COMMAND message.
e.g.
WPARAM wParam = (WPARAM)(((WORD)BN_CLICKED << 16) | ((WORD)GetDlgCtrlID()));
GetParent()->SendMessage(WM_COMMAND, wParam, (LPARAM)m_hWnd);
where m_hWnd is the HWND of the control and GetDlgCtrlID() returns the id of the control.
The message arrives to that CWnd you sent it. In your situation, you send the message to MyTaskPanel, so MyTaskPanel should process the message. If you want to send a message to other CWnd object , you should call SendMmessage fct. for that object : pMyView->SendMessage(...)

Thanks for the answer
but i don't have a HWND. I will sent the Message from out the Component.
The component should send a message to the window where it's placed.
Because the components gets the universal click on the component
The OnClick-Function determinates which button is clicked and the component sends a new message
to the window by specifing which Button is clicked ( over the ID )
Thanks

You will also find that your code may work in Debug build, but when you build a release version, it will crash.
The reason is that the SendMessage actually sends the command and a WPARAM and LPARAM. You must handle those in your message handler:
void ThePane::On_ID_OF_CLICKED_BUTTON_Click(WPARAM, LPARAM)<br />
{<br />
int test = 9;
}Karl - WK5M<br />

I found the error
I send the Message from the Pane, but that's wrong
I must send the Message from the Parent of the Pane.
GetParent()->SendMessage(WM_COMMAND, wParam, (LPARAM)NULL);
Thanks nevertheless

Hi all,
i am doing project in MFC. up to this moment i used visual studio 6.0
IDE for my developement purpose. but because of some reasons i shifted
Visual studio 2003 Version 7.1.3088.
i migrated all my project to this version and now when i create a final
release.
and run it on other machine that does not have .NET or .NET framework
installed on it
gives an error by saying mfc71.dll not found.
so is it necessary to install .NET framework on the client's computer
to run my application??
Thanks and regads

Try this:
In project settings search for "Use MFC in a Static Library" in Project>Properties>General > Use of MFC and select and apply it.
Somethings seem HARD to do, until we know how to do them.

If you write a program using .NET, it will require the pertaining framework to be installed in the target machine where you run the program. Linking the files statically may result in an increased size of the application.

NO !!!!
he's programming MFC !
so only the MFC71.dll, MSVCR71.dll and MSCVP71.dll may be necessary

don't confuse, installing Visual Studio .NET doesn't mean you actually use the .NET framework.
if your program is pure MFC project, then provide the MFC71.dll, MSVCR71.dll and MSCVP71.dll libraries with your exe (or statically link your project to MFC, but that'll increase the .exe file size significantly)...

Thanks for replying.
as you said i think it does not use the framework it's running in pure MFC.
so by putting these dll's on client's machine will be suffice..
Thanks

Ship all required dll's on client m/c. No need to install .net framework.
Use depends.exe for detecting dependencies.(It will show files mentioned by you).
|
|
|
|
|
.NET 2003 include VC7.0 , Convert VC6.0 project to VC7.0 , then rebuild all .
No need other dll , no need .NET framework.

I need to know when a copy event occurs in the explorer. I think I must set a global hook using SetWindowsHookEx API. But which type of hook it has to be?
|
|
|
|
|
You can write an ICopyHook shell extension to get those notifications.
|
|
|
|
|
That seems to work only for folders. I want my application to know immediately when user is copying one or more files. Will a clipboard hook help? Is there any other way to do this?
