CTreeCtrl::Expand

Use the root node as the HTREEITEM and TVE_EXPAND as the 2nd arg

Hi,
I saw that Control, but that control is too heavy.
I just want to Display the Directories and not the
Files etc.

Actually i just want to give a user, selection of a
Directory.

Please help

You can limit the tree to one level.

Use the foll. code

CString GetUserDirectory()
{
	CString strPath ;
	char szDisplayName[_MAX_PATH] ;
	char *szPath = NULL ;
	char *szTitle = _T(" Please Locate Directory : ") ;//Title of Locate Dialog
	
	BROWSEINFO bi = {0} ; //Init to NULL,so we do not have to fill up some members explicitly to NULL
	
	bi.pszDisplayName	= &szDisplayName[0] ;
	bi.lpszTitle		= szTitle ;
	bi.ulFlags		= BIF_RETURNONLYFSDIRS | BIF_RETURNFSANCESTORS ;
	bi.hwndOwner		= NULL ;
	
	LPITEMIDLIST pidl = SHBrowseForFolder(&bi) ;
	if( pidl == NULL ) //User has cancelled operation
		return strPath ;
	
	//Error Check 
	if( !SHGetPathFromIDList(pidl,szPath) )
	{
		AfxMessageBox(" The Path is Invalid ! ") ;
		return strPath ;
	}
	//Release the PIDL thru Shells MAlloc
	IMalloc *pMalloc = NULL ;
	HRESULT hr =  SHGetMalloc(&pMalloc) ;
	if( !SUCCEEDED(hr) )
		return strPath ;
	
	pMalloc->Free( (void*)pidl ) ;//Release the PIDL
	pMalloc->Release() ;//Release the Interface 

	strPath = szPath ;//The Path to the Directory
	return strPath ;
}

CEdit box

Hi, How do I determine when the user has finished entering text in an edit box. In other words, how do I know he has pressed the enter key and has completed typing in the text.

Write a handler for EN_KILLFOCUS

Sorry, I should have expressed myself better.
I know about Killfocus, but this requires that the user clicks elsewhere so that the focus on the edit box may be lost. Is there no other way?
Is there a way to call an event when the Enter key is pressed?

I tried using OnKeyDown, but am not sure how it works as I got no action from this event.

Hi,

You cannot trap enter from an edit box in the parent, you need to
derive a new class from CEdit and process the WM_CHAR mesgs

Haven't tried it now, but I think you can use PreTranslateMessage to get the WM_CHAR for the edit box, so you don't need to subclass it.

Another thing is, usually you have a default button in your dialog, so pressing enter will activate the default button, and the edit box gets an EN_KILLFOCUS message.

You wont get WM_KEYDOWN/WM_KEYUP messages in a dialog based application. I have written an article on how to go about trapping keys in dialog apps.

Sockets object transportation

Roger Allen23-May-02 2:46

Override the parents class PreTranslateMessage and put in this code:

// note, m_Edit is  CEdit control variable
if (pMsg->message == WM_KEYDOWN && pMsg->wParam == VK_ENTER && GetFocus() == &m_Edit)
{
pMsg->wParam = VK_TAB ;
}
// call base class

This code converts the ENTER key for that edit control only to a tab, so the EN_KILLFOCUS will be called regardless of whether the user uses the mouse, tab or enter key when ficnishing entering text.

If I had a quote, it would be a very good one.

Hi,

i'm looking for a simple example on how you can transport a class over a socket. I read somewhere that it involves serialization but i don't know how to do this exactly.
The only workaround i know of, is to serialize the class to file and then to transport the file. Transporting it directly is what i'm looking for and that involves streaming, right?

Preferably not in MFC but if it is, that's ok too

Thanks
