I'm using an free-threaded in-proc DLL server (written in ATL 7.0) which creates a separate thread for asynchronous I/O. If I terminate the separate thread by an interface command (using a terminate event to signal the thread's WaitForMultipleObjects loop), everything works as expected - the thread terminates, and any subsequent GetExitCodeThread call shows the proper exit code.
However, if I wait for COM to call DllMain with DLL_PROCESS_DETACH and then try to terminate the thread, I find that the tread exits, but a subsequent GetExitCodeThread call will return STILL_ACTIVE, and a WaitForSingleObject(hMyThread, INFINITE) call will hang up forever. It seems as though once the
DLL_PROCESS_DETACH is called, the kernel can no longer see that the thread has exited.
Is this correct behavior? If so, why? I was expecting the kernel could always see the thread's exit.
Thanks for any help,
Richard

Hi!
I have a CFrameWindowImpl-based main frame on Pocket PC 2003 and the newly released WTL. I can not get menu state updating to work using the update ui feature of WTL. I believe the relevant parts of the class definition are these:
class CMainFrame :
public CFrameWindowImpl<CMainFrame>,
public CUpdateUI<CMainFrame>,
public CIdleHandler,
public CMessageFilter
{
public:
DECLARE_FRAME_WND_CLASS(APP_MAINFRAME_CLASS, IDR_MAINFRAME);
BEGIN_UPDATE_UI_MAP(CMainFrame)
UPDATE_ELEMENT(IDM_HIDE_WEEKEND, UPDUI_MENUPOPUP)
END_UPDATE_UI_MAP()
BEGIN_MSG_MAP(CMainFrame)
...
CHAIN_MSG_MAP(CUpdateUI<CMainFrame>)
CHAIN_MSG_MAP(CFrameWindowImpl<CMainFrame>)
END_MSG_MAP()
...
};
In CMainFrame::OnCreate() I then do
...
CMessageLoop* pLoop = _Module.GetMessageLoop();
ASSERT(pLoop);
pLoop->AddMessageFilter(this);
pLoop->AddIdleHandler(this);
UISetCheck(IDM_HIDE_WEEKEND, true, TRUE);
...
which, unfortunately, doesn't check the menu item.
Any ideas what might be goin on here? Did I miss something?
I can see with UIGetState() that UISetCheck() sort of works, since the state includes the checked bits, but the menu item is not updated! No check mark is drawn!
I can set check marks using raw API, but hey, WTL is supposed to do this for me! So, please...
Thanks for _any_ pointers!

Funny you mention this. I was baffled today when I noticed that I couldn't disable menu entries using CUpdateUI<>
Maybe there's a bug in the new WTL release.

Seems as a bug in atlframe.h:
The CUpdateUIBase message map entry for WM_INITMENUPOPUP and its message handler are #ifdef-d off for Windows CE. Remove these #ifdefs and menu ui updating works.
Note: AtlIsOldWindows() needs to be modified to take Windows CE version numbering into account, or a debug break will occur there in debug builds after the #ifdef removal.

You should use basic_string::replace(). MSDN has a sample on how to use it.
|
|
|
|

// Copyright(c) 2002 by Kolya Kosenko
void replace_string(string &str, const char *search, const char *repl_value)
{
string::size_type size = char_traits<char>().length(search);
string::size_type repl_value_size = char_traits<char>().length(repl_value);
string::size_type replace_pos = 0;
if(size) {
do {
replace_pos = str.find(search, replace_pos);
if(replace_pos == string::npos) break;
str.replace(replace_pos, size, repl_value);
replace_pos += repl_value_size;
}while(true);
}
}

MESSAGE_HANDLER(WM_ERASEBKGND, OnEraseBkgnd)
MESSAGE_HANDLER(WM_SIZE, OnSize)
MESSAGE_HANDLER(WM_DESTROY, OnDestroy)
COMMAND_ID_HANDLER(ID_SEARCH_PLACE_BTN, OnPlaceBtn)
COMMAND_ID_HANDLER(ID_SEARCH_ATTRIBUTE_BTN, OnAttributeBtn)
COMMAND_ID_HANDLER(ID_SEARCH_START_BTN, OnSearchStartBtn)
COMMAND_ID_HANDLER(ID_SEARCH_STOP_BTN, OnSearchStopBtn)
CHAIN_MSG_MAP(baseClass)
END_MSG_MAP()
LRESULT OnAttributeBtn(WORD /*wNotifyCode*/, WORD wID, HWND /*hWndCtl*/, BOOL& /*bHandled*/)
{
CSearchAttributeDlg dlg;
dlg.DoModal();
return 0;

I want to call a MFC dialog from the docking window in a WTL project, but it can not be compiled. the message is :
error C2504: 'CDialog' : is not defined.
how to solute it?
Thank you

You have to add a MFC support to a WTL project. Just create a new WTL project using the wizard and check a checkbox 'Add MFC support' and see what includes were added to stdafx.h file.

|

|
|
Thank you.
With Daniel's help, I wrote a program in which I added a dialog into a docking window.

Hello.
Thank you for this reply.
BTW, where is the checkbox 'Add MFC support' ?
I created a new WTL project but not the check box displayed.

Ooops! Sorry, my fault. It was in WTL wizard that was supplied with WTL 3.0.
|
|
|
|
|
Hello.
Thank you for the reply.
Now I am using WTL7.1, is there anything like "Add MFC support"?
-Freehawk
|
|

If you are using VC7 create a test ATL project, go to application settings (part of the project wizard), uncheck Attributed checkbox, select DLL server type, check Support MFC checkbox, look at stdafx.h file and copy all afx*.h files to your projects.
It should do it.
Good luck,
Igor.

Hello
I did a test WTL project as the following
1.Open VC.net 2003 and create a new project(select "ATL/WTL Application Wizard")
but I can not find Attributed checkbox.where is it?
-Freehawk
|
|

|

Not ATL/WTL project, select a template called "ATL Project". Click OK. You'll see "ATL Project Wizard" dialog. By default an "Overview" tab is opened, switch to "Application Settings" tab.
There you'll find it. (I'm also using VC 2003, I just did it).
Good luck,
Igor.

Hello.
Thank you for reply so fast.
I will try it. In fact, I am using VC6.0 and WTL7.1 to make my project. And in the WTL project, I want to use MFC, If done as you said, can it be realized?
-Freehawk
|
|
|
|
|
In VC6 you should select ATL COM project type, click OK. On the next page select DLL server type, check Support MFC checkbox, finish creating a project and then look at stdafx.h file.
Good luck,
Igor.

Hi,
Can anyone tell me if there is a limit of 2^15 (32768) items that can be sorted in a list using the list function sort()?
I am trying the following code in Visual C++ 6 on Windows 2000.
std::list<int> TestList;
for (int i=0; i<40000; i++)
TestList.push_back(i);
int nSize = TestList.size();
test.sort();
int nSize2 = TestList.size();
nSize is 40000.
nSize2 is 7232.
The difference between the two values is always 32768.
Less than 32768 values sorts fine.
NOTE: max_size() returns a value of > 100000000.
I could not find any information that mentions this limit but it is clearly there.
Can anyone suggest an alternative?
