Re: CAsynSocket CWinthread Question

Well yeah, but since you're already using a message pump, why not send a message instead of raising an event?

i.e. (from your sender thread)

PostThreadMessage MY_STOP_MESSAGE
....
PostThreadMessage MY_RESUME_MESSAGE

instead of

SetEvent MY_STOP_EVENT
....
SetEvent MY_RESUME_EVENT

if i can use double dimension array in the declaration like

To make this compilable, you'll need to make a larger and correct the syntax errors:

int a[2][5] =
{ 
    {1,2,3,4,5},
    {2,4,6,8,9}
};

Just search on google man Smile | :)

clue:- INetConnectionManager in vc++

More clue:-
u need three interface to do that

INetConnection* pConnect
INetConnectionManager* pMgr
IEnumNetConnection* pEnum

Using pMgr->EnumConnections( NCME_DEFAULT, &pEnum ) get all the connection

Loop it and check whether "Local Area Connection" or what ever connection you want to check

and call pConnect->Disconnect() to disconnect your NIC.

Print Preview on Main frame in MDI Application

Harsh Shankar6-Aug-09 2:01

6-Aug-09 2:01

Hi All,

I am working on VC2008's MDI application with Ribbon bar and have to provide print preview.

Now, However VC2008 do have print preview, but the client requires it to look it like the VC6.0's Print preview capturing the entire main frame along with some certain buttons, all like VC6.0.

Can some body please help me on it

I'm not sure if it'll do what you want, but try this:
Find OnFilePrintPreview in your CView-derived class and replace its code with this:

void CYourViewDerivedClass::OnFilePrintPreview()
{
// 	AFXPrintPreview(this);


// 	ASSERT_VALID(pView);

	CPrintPreviewState *pState= new CPrintPreviewState;

	if (!DoPrintPreview(IDD_AFXBAR_RES_PRINT_PREVIEW, this, RUNTIME_CLASS(CPreviewView), pState))
	{
		TRACE0("Error: OnFilePrintPreview failed.\n");
		AfxMessageBox(AFX_IDP_COMMAND_FAILURE);
		delete pState;      // preview failed to initialize, delete State now
	}
}

Hi sashoalm,

First thanks for replying...

I already know the way how to prepare print preview. But i guess i was not clear enough with my requirement.

My requirement is to show the preview capturing the entire main frame including all Menues, Panes, Views etc in VS 2008, how VS 6.0 does.

In VS2008, the preview comes like a view only and menues etc are remain enabled..

Please suggess something else may be that will help...

Thanks

OK, CMainFrame should have CMainFrame::OnFilePrintPreview method, try to place the code I posted in CMainFrame::OnFilePrintPreview instead and tell me what happened.

Hi,

There is an issue in doing as you are saying but there is no such function "DoPrintPreview" in class CMDIFrameWndEx from which the CmainFrame Class is derived..
However, i already have tried:

CView *pView = GetActiveFrame()->GetActiveView();
if(pView == NULL)
{
	return;
}
CPrintPreviewState* pState = new CPrintPreviewState;
    
if (!pView->DoPrintPreview(AFX_IDD_PREVIEW_TOOLBAR, pView,
	RUNTIME_CLASS(CPreviewView), pState))
{
	delete pState; // Preview failed to initialize, delete State now.
	pState = NULL;
}

But it prepares the preview in the same document only and not capturing the frame.
And this not what i wanted Frown | :(

Please suggess something else.

What about minimizing the ribbon? Try minimizing the ribbon before print preview and see if you like it.

It is not practically possible and good to hide all the ribbons, views and panes on Preview and restore them OnEndPreview since the are many in count..

Like in VC 6.0, i didn't needed to do any thing like that and the compiler was doing this for me, i want something like that.

Thanks

What do you mean by that? You right-click on the ribbon bar and there's "Minimize the ribbon" *by default* in every MFC9 program. Why didn't you use that? Just do it and see how it looks. Not programatically - as a user - click on "Minimize the ribbon".

Hi sashoalam,
So do you think i should minimize all the Ribbons by some explicite call. But don't you think, making calls for hiding all the views, menues, tabs, Panes etc and maintaining its previous states is not really a good idea if you may have about 10 Ribbon-tabs, about 10-20 Panes and uncountable Views are possible.

Event on remembering the 6.0 days, you'll notice that we didn't have to do all those things by us and it was MFC's responsbility to do so.

i think must have understood my problem.
