Oh! That is totally dependent on the object that is being embedded.
Those are custom properties I guess.

In the wizard I'm working on I need to bring up a window that allows our users to select a folder to gather files from. I figured that CFolderDialogImpl would work just dandy. However, I wanted to remove the 'Make New Folder' button (which I was able to do by using Spy++ to find out it's ID and hide it) and replace it with a check box that the user can check to specify whether or not to recurse into subdirectories of the selected folder. I created a dialog in the resource editor with just a checkbox in it (IDC_CHECK_RECURSE is the resource ID for the checkbox, and it belongs to IDD_ENHANCED_FOLDER_DIALOG).
My problem is that I can't, for the life of me, get the check box that I created in the resource editor to show up! I know that I haven't set anything up to handle the messages for my check box. I'm more concerned with just getting the dang thing to show up first.
Here is what the class looks like...
class CFolderDialogEx : public CFolderDialogImpl<CFolderDialogEx>
{
protected:
typedef CFolderDialogImpl<CFolderDialogEx> baseClass;
typedef CFolderDialogEx thisClass;
public:
enum DialogIds
{
_IDC_STATUSTEXT = 0x00003741,
_IDC_TITLE = 0x00003742,
_IDC_NEW_FOLDER = 0x00003746,
};
enum { IDD = IDD_ENHANCED_FOLDER_DIALOG };
CFolderDialogEx(HWND hWndParent = NULL, LPCTSTR lpstrTitle = NULL, UINT uFlags = BIF_NEWDIALOGSTYLE | BIF_RETURNFSANCESTORS | BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT)
: baseClass(hWndParent, lpstrTitle, uFlags)
{
}
BEGIN_MSG_MAP(thisClass)
END_MSG_MAP()
void OnInitialized()
{
if((m_bi.ulFlags & BIF_NEWDIALOGSTYLE) == BIF_NEWDIALOGSTYLE &&
(m_bi.ulFlags & BIF_STATUSTEXT) == BIF_STATUSTEXT)
{
int fontHeight = 11;
CWindow title = ::GetDlgItem(m_hWnd, _IDC_TITLE);
RECT rcTitle = {0};
if(title)
{
CFontHandle titleFont = title.GetFont();
CLogFont logFont;
titleFont.GetLogFont(logFont);
if(logFont.lfHeight < 0)
fontHeight = -1*logFont.lfHeight;
title.GetWindowRect(&rcTitle);
::MapWindowPoints(NULL, title.GetParent(), (LPPOINT)&rcTitle, 2);
rcTitle.top -= 1;
rcTitle.bottom -= fontHeight + 1;
title.SetWindowPos(NULL, &rcTitle, (SWP_NOACTIVATE | SWP_NOZORDER | SWP_SHOWWINDOW));
}
CWindow status = ::GetDlgItem(m_hWnd, _IDC_STATUSTEXT);
if(status)
{
status.EnableWindow(TRUE);
status.ModifyStyle(0,SS_PATHELLIPSIS|SS_NOPREFIX);
rcTitle.top = rcTitle.bottom + 2;
rcTitle.bottom = rcTitle.top + fontHeight + (fontHeight/2);
status.SetWindowPos(NULL, &rcTitle, (SWP_NOACTIVATE | SWP_NOZORDER | SWP_SHOWWINDOW));
}
}
CRect rect;
CWindow makeNewFolderButton = ::GetDlgItem(m_hWnd, _IDC_NEW_FOLDER);
if ( makeNewFolderButton.IsWindow() )
{
makeNewFolderButton.ScreenToClient( &rect );
makeNewFolderButton.ShowWindow( SW_HIDE );
CWindow recurseBox = ::GetDlgItem( this->m_hWnd, IDC_CHECK_RECURSE );
DWORD error;
error = GetLastError();
if ( recurseBox.IsWindow() )
{
recurseBox.MoveWindow( &rect );
recurseBox.ShowWindow( SW_NORMAL );
}
}
}
....
recurseBox.m_hWnd is NULL, which makes the if ( recurseBox.IsWindow() ) fail.
error is ERROR_CONTROL_ID_NOT_FOUND
I'm completely aware that I may be going about this all wrong. All I want to do is have a folder dialog with the checkbox that let's the user specify whether or not to recurse into subdirectories. I don't really care how it gets done, as long as it gets done. Any help would be very much appreciated!
Thanks!

I'd be tempted to do it slightly differently for various reasons, the main one being that I don't think SHBrowseForFolder (the underlying API) allows controls to be added to its dialog.
Anyway - why not have a separate dialog with three controls - an edit box containing the text of the path, a 'browse' button that would show the folder browsing dialog (the result of which would get put back into the text box) and a check box for the recursion control.

The following code is correct:
FRLE_FALSE(m_pRssManager.CreateInstance(RssLib::CLSID_RssManager),_T("can't create RssManager object"));
CString sRssDBFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\DB\\RssTab.mrr"));
try{
m_pRssManager->Open((LPCTSTR)sRssDBFile);
}
catch(...)
{
MessageBox(::AfxGetMainWnd()->m_hWnd, _T("database file is already damaged,will create a new empty database file"),_T("message"),MB_OK|MB_ICONINFORMATION);
CString sRssDBTemplateFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\NewRssTab.mrr"));
if( ::PathFileExists(sRssDBTemplateFile) ){
::CopyFile(sRssDBTemplateFile, sRssDBFile, FALSE);
RssLib::IRssManagerPtr pRssManager;
FRLE_FALSE(pRssManager.CreateInstance(RssLib::CLSID_RssManager),_T("can't create RssManager object"));
pRssManager->Open((LPCTSTR)sRssDBFile);
m_pRssManager = pRssManager;
}
}
the following code is not correct:
FRLE_FALSE(m_pRssManager.CreateInstance(RssLib::CLSID_RssManager),_T("can't create RssManager object"));
CString sRssDBFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\DB\\RssTab.mrr"));
try{
m_pRssManager->Open((LPCTSTR)sRssDBFile);
}
catch(...)
{
MessageBox(::AfxGetMainWnd()->m_hWnd, _T("database file is already damaged,will create a new empty database file"),_T("message"),MB_OK|MB_ICONINFORMATION);
CString sRssDBTemplateFile = (LPCTSTR)(GlobalSet::g_sRootPath + _T("\\NewRssTab.mrr"));
if( ::PathFileExists(sRssDBTemplateFile) ){
::CopyFile(sRssDBTemplateFile, sRssDBFile, FALSE);
m_pRssManager ->Open((LPCTSTR)sRssDBFile);
}
}
May I ask the reason ? Why have to recreate the RssManager object ?
thanks a lot!

Try formatting the code using the 'code block' button, so that indents aren't lost - that is pretty much unreadable, which makes it unlikely that someone's going to answer your query.

Hi,
I wonder for an ATL COM DLL, is there any way I can dynamically assign the UUIDs to the COM class and interface, i.e. without recompiling the code? Assume all the registries are setup correctly. Is it possible that when the dll gets loaded, the CLSID, IID are reset to the new value?
Thanks!
Lucy

This actually must be in the COM forum. Anyway...
You can use UuidCreate API to generate new UUIDs.
Replace the registry entries with the new UUIDs under CLSID and IID keys under HKEY_CLASSES_ROOT.
Do this after the COM DLL has been loaded.
This should work.

We want a Pointer list in ATL, similar to CPtrList in C++
|
|
|
|
|
Don't think there is one as such. What type are the pointers?
|
|
|
|
|
Thanks!
Class Object Pointers, we need to store it an List to track the objects created, We are now using vectors for this purpose
|
|
|
|
|
If as you say you need to store in a List it's probably best to see Stuart's answer, though vector will or course do the job.
|
|
|
|
|
Would a standard list of pointers do, i.e. std::list<MyType*>?

CPtrList is not in c++, it is in vc++

Hi,Am NATARAJAN from mumbai.I wanted to clarify a doubt that,whether in Adobe Acrobat Reader version 6.0,Add-ins can be developed?If so what's the logic & development procedures involved in it?
Iam using Windows-XP as OS & VC++6.0(ATL/COM) as tool.
Thanks in advance,

I am creating an ATL/WTL application in which i need to create a window.I have created the window now i need to create button, label and list view on it dynamically and attach these controls to the main window.
Also i have classes for button and labels....like CMyButton....etc
Please help..?
Thanks in advance.

Create using the parent and position as parameters, making sure they are set to visible. Messages from controls are WM_COMMAND with the controls ID as a parameter.

Thanks for the reply  .
But can you please provide a sample code snippet to make it more clear.........?
|
|
|
|

Sorry I don't have any code that I can find, I just seem to remember doing this sort of thing. I had a quick look on the net... and found an MS MFC example [^] which should translate to ATL. What have you tried?

Hi all,
I have an ATL control based on CComCompositeControl. In the control's dialog box I have a web browser, from which I am sinking events. I also have another COM object which is not on the dialog box from which I'm sinking events. I'm getting an assert thrown as my control initialises in AtlAdviseSinkMap. In this ATL method there is a loop which goes over all the ids of the sink entries and calls:
HWND h = pT->GetDlgItem(pEntries->nControlID);
ATLASSERT(h != NULL);
While this works perfectly for the embedded web browser, the other object not on the dialog box causes an exception.
Is there a setting I can use to inform the initialisation that it is not a dialog object and that this is not appropriate but without the assert being thrown.
Many thanks
Cheers
Tom

You must have added that setting somehow. Just taking some example code from an ATL object of mine that sinks events from a non control as a guide I have: a typedef to make things readable:
const UINT ID_QUEUEDEVENTS = 1;
typedef IDispEventImpl<ID_QUEUEDEVENTS, CMSMQEventControl, &DIID__IQueueMonitorEvents ,&LIBID_MSMQEVENTTEST2Lib ,1,0> IQueueMonitorEventSink ;
Then the beginning of class which inherits (the typedef):
public IQueueMonitorEventSink,
Then a sink map for the events:
BEGIN_SINK_MAP(CMSMQEventControl)
SINK_ENTRY_EX(ID_QUEUEDEVENTS , DIID__IQueueMonitorEvents, 1, QueuedMessage)
SINK_ENTRY_EX(ID_QUEUEDEVENTS , DIID__IQueueMonitorEvents, 2, QueuedError)
END_SINK_MAP()
Do you have something different?

Hi, thanks for the response.
I have something very similar.
In my class declaration I have:
public IDispEventSimpleImpl<0, COfficeDlgX, &__uuidof(_IOfficeAutomaterEvents)>,
public IDispEventImpl<IDC_WB,COfficeDlgX>,
In my class I then create a typedef for calling the advise method.
typedef IDispEventSimpleImpl<0, COfficeDlgX, &__uuidof(_IOfficeAutomaterEvents)> OfficeAutomaterEventsImpl;
Then I generate the sink map:
BEGIN_SINK_MAP(COfficeDlgX)
SINK_ENTRY(IDC_WB, 259, DocumentCompleteWb)
SINK_ENTRY(IDC_WB, 252, NavigateComplete2Wb)
SINK_ENTRY(IDC_WB, 250, BeforeNavigate2Wb)
SINK_ENTRY_INFO(0, __uuidof(_IOfficeAutomaterEvents), 1, &COfficeDlgX::__OnDocumentClosed, &OnMenuItemClickedInfo)
SINK_ENTRY_INFO(0, __uuidof(_IOfficeAutomaterEvents), 2, &COfficeDlgX::__OnMenuItemClicked, &OnMenuItemClickedInfo)
END_SINK_MAP()
in my code, when I create an instance of IOfficeAutomater I call:
hr = OfficeAutomaterEventsImpl::DispEventAdvise((IUnknown*)m_spOfficeAutomater, &__uuidof(_IOfficeAutomaterEvents));
IDC_WB is the dialog id of my WebBrowser.
I don't have to call DispEventAdvise for the web browser control myself as the framework does it for me. It does it by using the id to get to the control. Herein lies the problem. Somehow, the framework now thinks all the sink entry ids refer to an item on the dialog box. The system therefore runs through all the sink entry id and calls GetDlgItem with them. When it uses the id of my non dialog item ie 0, it of course comes back NULL. This value runs through an assert and hey presto I get a message box up telling me something's wrong.
On one hand it's only an assert and so it won't come up in the release build and it in no way affects whether my app works or not but it does seem very messy. What would be ideal is having two sink maps. One for dialog items and the other for anything else.
Cheers

Looking at my ATL Internals (B.Rector & C.Sells) they say:
Easiest way...event sinks...derive ... from IDispEventImpl...
... when the event source is a contained control and the event recipient is a composite control, the identifier is the contained control's child window identifier.
When your class is a composite control, you should use the AtlAdviseSinkMap function to establish and remove connections...of the contained controls listed in the sink map...Using CWindow::GetDlgItem method, AtlAdviseSinkMap navigates to a child window handle...
When your class isn't a composite control you must explicitly call the DispEventAdvise method of each of your IDispEventSimpleImpl ... base classes to connect.
You seem to have the correct use of IDispEventImpl and IDispEventSimpleImpl. It also seems use of AtlAdviseSinkMap is out due to its requirement of "contained controls listed in the sink map" as one of your mapped controls isn't contained - as you say. So it seems you can't prevent AtlAdviseSinkMap calling GetDlgItem.
All it would seem you can do is not use AtlAdviseSinkMap but do it manually by using GetDlgItem etc on one and "explicitly call the DispEventAdvise" of the other (or both).

If I have a c++ template class declared in Point.hpp file as below
template <typename>
class Point
{
....
}
If I want a new class derived from the above class in Node.hpp file but the data type is specialized to be double:
class Node: public Point<double>
{
...
}
When I compile the codes, the compiler complains that in Node.hpp that the base class Point is undefined. I know that I have included Point.hpp in Node.hpp. Why that error? Or how can I derived a node class (which should be a non template class) from a template Point class with double data type?
