in which I am calling SubclassWindow(HWND) function

I don't know how many times I've asked why...

All my MFC controls for the past decade have got mouse messages just fine without calling subclassWindow...

Dear Mark,
First of all, I am very sorry if I have tested your patience, although unknowingly and unintentionally. I have some big code of my project, which was running fine in Visual C++ 6.0(in which it was first written), but which I now needed to convert to Visual C++ 2005. After everything I have explained till date, since the functionality(mouse events) after conversion is not running in VC 2005, I created my own MFC application in VC 2005, in which, like the project code, I tried using CWnd's SubclassWindow(HWND). Since this functionality was running in VC 6.0, I need to keep and also make it run in VC 2005. Hence the inclusion of SubclassWindow also in my code(the sample application which I am trying these things in). I hope I am very much clear this time. Could you please help?

Print in an SDI application

Hi,

In my MFC SDI application, there is a "File | Print" automatically created from the wizard which prints my CHtmlView successfully.

Now I would like to issue this command *manually* from my view.

Which method do I need to call?

Thank you!

Is ShellExecute (with verb "print") helpful ?

Hi,

I do not think so; I have dynamic HTML code written to my CHtmlView which I want to print the same way as with File | Print.

I tried a little bit with ShellExecute but it does not work as expected.

Regards,
Niki

Use this code snippet to print your view from anywhere. The core idea is to call CView::OnCmdMsg() by passing ID_FILE_PRINT or ID_FILE_PRINT_DIRECT.

// Get the active view.
CFrameWnd* pFrameWnd = (CFrameWnd*)AfxGetApp()->GetMainWnd();
CView* pView = pFrameWnd->GetActiveView();

if( pView != NULL )
{
    // Send Print message. 
    // If you want to print directly, then change ID_FILE_PRINT to ID_FILE_PRINT_DIRECT.
    pView->OnCmdMsg( ID_FILE_PRINT, 0, 0, 0 );
}

Regards,
Jijo.

Thank you, I think this is exactly what I was looking for Smile | :)

I'm inside my view anyway, so

this->OnCmdMsg( ID_FILE_PRINT, 0, 0, 0 );

does exactly what I want Smile | :)

Please check your ListCtrl is in LVS_REPORT mode then first Insert column

You should use LVSIL_SMALL instead of LVSIL_NORMAL if the list control is in report view.

Thanks for the reply.

Not by using an API. I want to simulate the real scenario. I am trying to generate the memory dump after the exception. So I wanted to simulate the real exception.

One possibility is to OwnerDraw. Check out these articles below,

1. Changing row height in owner drawn control[^]
2. Changing Row Height in an owner drawn Control[^].
3. One Thread[^] which says how to change CListCtrl's row height by using CImageList.

Flash swf

Nishad S2-Jan-09 0:41

Hi,

I need to play swf file in VC++ application using flash ocx.

One condition is that, swf file should not be played if the user open the file in normal flash player. So something should be done at the flash side (I am not so clear about how to do that right now). But it should be played only from my application (A kind of protection from playing and so spreading the files discreetly).

(I am thinking about some method to pass some values to swf script. And there, if the passed value is checked and if it is OK then only allow to play the swf.)

I wish to get ideas from you. Probably some of you had gone through such a requirement... Smile | :)

Thank you.

Thank you...

But it is just about telling how to load the file. I can load the file by inserting the flash ocx in to my (MFC) application. There is no problem at all.

I actually need to make the swf file played only by my application. I know both the application side and the flash side need something to be done for that. So I wish to get ideas regarding this.

I am also googling for some solutions... but not got yet... so continuing the search... Smile | :)

1) One method is to corrupt the file, which you know how to reverse back. All the SWF files formats start with "CWS". So modify your flash file by changing it to something like this - "CWT" or something like that. When you play the file, check whether the file starts with "CWT" and in that case reverse it to "CWS" and play. Once played, corrupt it again.

2) Another method is to encrypt the entire file and for playing in you application decrypt it back.

Well, if you need to know how to play swf in VC++ application, then check out this tutorial - How to display Flash animation in Visual C++ MFC application[^]

This is a good idea... Smile | :)

But please don't feel bad, I would like to take this as a last resort... Wink | ;)

Because if I get some other direct method, I will follow it...

Actually I know how to play the swf in VC++. But have no better experience...

Thank you very much for sharing your thoughts... Smile | :)
