Software Deployment in VC++ programming ???

In Win2000, we could use Active Directory and Group Policy to install and maintain softwares. But how we could create and access the group policy to deploy or publish software in VC++ programming ???

Thank a lot.

AfxBeginThread failed create thread

hi all,
pls try to answer my question, thanks!
i found that the AfxBeginThread failed to create thread for my function after a long run.
in my program, i need to run a thread, terminated after few mins and restart it.
however, i found it failed to restart after it run for few days (around 3000 times restart).
it just return the NULL pointer to me. eventually, it crashed as i terminate the thread with such pointer.

so, anyone know any reason a AfxBeginThread failed to create thread?
(if i don't know the reason, it is hard for me to try any debug method. since i can't monitor the bug as it occurs after long run.)

thanks,
jim

HEY
i heard that AfxBeginThread() has some problems related with the releasing of memory when u terminate the thread.(releasing the kernal thread object).i think that may be the reason...but
_beginthreadex() is safe and smart among the thread functions...no probs even if u restart 10 ^300000 times..!!haha

thank you for your answer!
but, would you give me some idea about _beginthreadex()?
thanks,

Re: AfxBeginThread failed create thread

25-Jun-02 15:22

Surely..

_beginthreaex(void* Security,unsigned int stacksize,unsigned __stdcall*startAddressof ur thread Function,void *argumentList,unsigned initflag,unsigned* threadID);

that function will returnes the ThreadHandle...

First, this kind of questions can simply _not_ be answered correctly without code sample.
Secondly, this kind of questions may even _not_ be answered correctly even with a code sample...

DocTemplate Stuff

24-Jun-02 15:33

I'm creating an MDI application. However, I wanna create the Doc/View/Frame on my own when the user has chosen an menu item (no in File New).

I coded like below, but I don't know how can I associate with a view ?

Besides, who'll manage the deletion of the Document ? Will the document be deleted when the user clicked the "X" button in the frame window ? I don't want the document be deleted as it will associate with another frame/view too, and I've to cache it.

<br />
CMultiDocTemplate *pTemplate=theApp.m_pScreenDocTemplate;<br />
		<br />
CShirleyScreenDoc* pdoc = (CShirleyScreenDoc *) pTemplate->CreateNewDocument();<br />
<br />
CShirleyScreenFrame *pNewFrame = (CShirleyScreenFrame *) pTemplate->CreateNewFrame(pdoc, NULL);<br />
<br />
if(pNewFrame)<br />
	pTemplate->initialUpdateFrame(pNewFrame, pdoc);<br />

Thanks ^^

As you need your document to be static I would create a document structure/class outside of a regular MFC type document that will store the cached data. You can then use

CMyDoc *pDoc = pTemplate->OpenDocument(NULL) ;
pDoc->m_pDataPointer = &CachedObject ;

which will create a normal document view/frame and attach a pointer to this global cached object. As long as you just set the pointer to NULL in the MFC document destructor and dont delete it, everything should work as you want.

Preselecting a Popup menu item

Does anyone know of a way to select a menu item for a popup menu which uses TrackPopupMenu(). ie. I want menu item 2 selected when the menu pops up, so pressing return will select it.

I've tried;

for( int iPos = 0 ; iPos < 2 ; ++iPos )
    ::PostMessage( (HWND)pCurMenu->GetSafeHmenu(), WM_KEYDOWN, VK_DOWN, 0 );

item_id = pCurMenu->TrackPopupMenu( TPM_NONOTIFY | TPM_RETURNCMD | bMenuOptsExtra,
                                    pt.x, pt.y, Thread_pCWnd(), NULL
                                  );

but it doesn't work. Any other ideas?

Don't know if it will work, but have you looked at ::SetMenuItemInfo()?

Thanks. Yes I have but there isn't anything there which helps. In fact there is nothing in the entire Menu API which does this that I can see, which is why I'm stuck.

Call SetDefaultItem() on the menu popup before you track it is a possibility.

I think that displays the item in bold, but doesn't highlight it.

Yes that's right. It is difficult to get any usefull info on SetDefaultItem(). Best I've come up with is it is used with drag and drop. It doesn't help me though. Thanks anywayz.

Neville, me thinks subclassing CPopupMenu should easily give you what you want.

Hi Ravi, I'm actually using Bruno's excellent CNewMenu code. This does subclass the menu but a) I am a little reluctant to start mucking around in the subclass code and b) I can't work out what I would do here anyway. Any suggestions?

Hi Neville,

I haven't looked at Bruno's article, but off the top of my head I'd do this:

Store the preselected id in a member variable.
Override the handler for "mouse on new menu item" (not WM_MENUSELECT) and clear the member variable.
In the OnDrawItem() override, draw the item as selected if its id matches the member variable's value (if non-zero). If the member variable is zero (i.e. has been cleared), just call the base class OnDrawItem().

I think the tricky part is handling the message "mouse on new menu item". I hope these thoughts end up being helpful and not a waste of time!

Hi Ravi,
Thanks for that - I'll ponder on it.

For all my years of Windows development I've always been frustrated by the menu handling code, but this isn't the time nor the place for that. Smile | :)

What do you mean, you want them? If you mean you want them on your hard disk, just right click and take save-as. If you mean you want them for your web site, you'll probably need Chris M's permission.

Getting Data from a Dialog in a an MDI Document

Matt Fenwick24-Jun-02 11:22

24-Jun-02 11:22

This is going to sound like a stupid question, but I can't find anything on how to do it. I have a text editor MDI that calls up a dialog box. I have the information saved as a CString in the dialog box, but now how do I get it from there and displayed in my document?

I've looked at the MSDN CD, and also this site, but I can't seem to find a step by step tutorial on how to do it. Can anyone help me to do this simple task, or at least point me in the right direction to find out?

Thanks
Matt Fenwick

I am just teaching myself MFC so I hope I don't steer you in the wrong direction.

Here is a tutorial I did tried this weekend. It should help. Note, there are a few errors but you should be able to get through it.

http://www.codeproject.com/dialog/dialogapptute2.asp

The tutorial takes data from a various controls and puts it in a list box and then to a dialog box, but the principle should be the same.

You can use the class wizard to make a member variable (I think you will use a category of "control") to hold the data you want moved to the document.

When you come to a fork in the road, take it! Y. Berra

Well, if your dialog is modal (i.e. you launch it with DoModal,) things are simple. You already mapped the string to some member variable of the dialog (let's say it's called m_str.) Then, after DoModal, the value is just there for you to use:

void CYourView::OnSomeParticularEvent()
{
  CYourDlg dlg;
  if(dlg.DoModal()==IDOK){
    // use dlg.m_str (for instance, to store it in your
    // CDocument-derived class.)
  }
}

I hope I made myself clear enough. Good luck with your project.
