Just ignore the voting system. It's so easily abused, the numbers mean nothing.

Use this loop ,

POSITION pos = dlg.GetStartPosition();
while (pos != NULL)
{
   CString sFileName = dlg.GetNextPathName(pos);
}

How to get the keyboard inputs

Hi all,

My application uses a spalsh screen for about 30 seconds and then the
main window appears.

During these if the user types any keyboard key ,the main window should appear immediately.

My code looks like this:

// *************** SPLASH SCREEN ***********************

// create a temp. invisible wnd. as parent of splash screen
if(m_wndOwner.m_hWnd == NULL)
{
LPCTSTR pstrOwnerClass = AfxRegisterWndClass(0);

if ( !m_wndOwner.CreateEx(0, pstrOwnerClass, _T(""),
WS_POPUP, CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL, 0) )
return FALSE;
}
int nDelay = 30000;

// Create and show the splash screen.

CSplashWnd::ShowSplashScreen(nDelay, BMP_MICATECH_BIG, &m_wndOwner);
Sleep(nDelay) ;

Can any one tell me how to overcome these problem?

Regards,
Veeresh

Don't use Sleep(nDelay),Sleep will block keyboard input.
Use OnTimer set delay time.
Use OnKeyDown get the typed keyboard key

Hello Comunity,
i have an litle trouble wit this data type! To add an new item in this object i use:

CMapStringToOb cMap;
CString csNewKey = "First";
CMyObject* myObject; // public CObject!
cMap.SetAt(csNewKey, new CMyObject());
// to add new items to my class CMyObject use:
cMap.Lookup(csNewKey, (CObject*&)myObject);
// now set data to myObject:
myObject->csName = "John";
// etc., this is only for example!

ok, works fine, but when i close my dialog, i recive memoryleaks!
And the debugger show in this line with -> cMap.SetAt(csNewKey, new CObject()); ?!

You have used new CMyObject ,in SetAt.
Somewhere you need to delete it. You can do it before cMap goes out of scope, enumerating it.

Hello,
i use other funktion to delete all objects befor closing dialog, looks something like this:

// before CDialog is closed!

POSITION pos = cMap.GetStartPosition();
CString csKey;
CMyObject* cMyObject;

while(NULL != pos)
{
   CMyObject* myOb;
   cMap.GetNextAssoc(pos, csKey, (CObject*&)cMyObject);
   
   delete cMyObject;
   cMap.RemoveKey(csKey);
}
// cMap is empty! 100%

i dont know what else to do! Frown | :(

Question is on witch place to set use "delete"? I need all data during program run, only solution is
before closing the dialog??

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 />
  // Determinates the button who's clicked<br />
  <br />
  TaskPanelGroup* Item;<br />
  <br />
  Item = HitTestGroup(point);<br />
  <br />
  UINT SelectedID;<br />
  if(Item) {<br />
    SelectedID = Item->GetID();                       // gets the correct ID of the Button<br />
    SendMessage(BN_CLICKED,(WPARAM)SelectedID,NULL);  // sends a message<br />
  } else {<br />
    // It wasn't a button<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; // I never step here<br />
}<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(...)
