The default button is the button that is activated when you press [enter]

When you press tab, the button that got focus is actually made the default button. This continues till the focus goes to a control that's not a button. Then the original default button is again made default.

You can do that too from within your code

>> made the default button
is this BS_DEFBUSHBUTTON button style, or setDefID in the dialog, or both? Do I have to reset it, handle Button.KillFocus etc?

Nish Nishant1-Nov-01 23:06

1-Nov-01 23:06

m_button.SetFocus();
DWORD original_default_id=SetDefID (IDC_BUTTON10);

That should do the trick.
By default you'll only get BN_CLICKED and BN_DOUBLECLICKED
If you wanta handle the KillFocus events you'll have to subclass it I guess....

CTabCtrl in CRecordView

Hi,

I am working on SDI Database application. I have a class CLibraryView inherited from the CRecordView. CLibraryView class has a formview dialog. I have inserted a CTabCtrl on the Form in the resource editor. OnInitialUpdate method of the CLibraryView I have updated the CTabCtrl to insert tabs.

// Insert First Tab
tci.pszText = "Issued Books";
((CTabCtrl *)GetDlgItem(IDC_TABMAIN))->InsertItem(0,&tci);

// Insert Second Tab
tci.pszText = "Library Books";
((CTabCtrl *)GetDlgItem(IDC_TABMAIN))->InsertItem(1,&tci);

// Insert Third Tab
tci.pszText = "Library Members";
((CTabCtrl *)GetDlgItem(IDC_TABMAIN))->InsertItem(2,&tci);

Now I want to insert the different layouts of CEdits & CButtons on different tabs. How can I do so? I mean each should have different layout. How to make it possible any idea in CRecordView scenario? I have an example in my book but it tells in simple CFrameWnd scenario where each stuff is created with Create member function.

Plz help......

Thanks for ur time .....

First, if you don't want to distribute the VC and MFC dlls with your dll you have to link statically to MFC. Not sure about the VC dll though, although they're probably present on all machines (I think they are Win2K system DLLs).

Second, your dll depends on debug versions of the VC and MFC dlls. This is a no-no. You should distribute a release version of your dll, not a debug one. Actually, you're not allowed to distribute the debug versions of the MFC dlls (don't know about the VC ones) - but since you don't want to distribute any additional dlls I guess this is an academic question Smile | :)

Anyway, distribute a release version of your dll, not a debug one.

Cheers
Steen.

Help !!!!

I am trying to get some data out of a piece of equipement via our network, using windows sockets.

Does anybody have any code which shows very easily how to connect to a ip address + port and send and receive data from it.

I have tried the examples from MSDN and it only gets as far as the Bind() then fails.

Any ideas ?

Window freezes when ActiveX is used in a DLL

1-Nov-01 20:58

Hi
I've put some source code below.
It'snot complete...
But it should give you a start

Nish

CSocket s;	
s.Create();
s.Connect("127.0.0.1",25);
CString buff;	
buff="helo buster\r\n";
s.Send(buff,buff.GetLength());
char rbuff[128];
s.Receive(rbuff,64,0);
buff=rbuff;
s.Close();

Refreshing setting after registry changed...

Microsoft released a web based app to change some fine tune settings with ClearType in WindowsXP. The setting FontSmoothingGamma is found in HKEY_CURRENT_USER\Control Panel\Desktop which controls this setting. Microsofts web program only allows for 6 different setting, so I created an app that gives a little bit greater control over the settings. My problem is that once the settings have been changed I need to force an update to reflect the new settings. In Microsofts web app as soon as you hit apply the settings are changed. Any help in that direction would be great! Smile | :)

The Microsoft app can be found here

Hey Nish, thanks for the reply. The WM_SETTINGCHANGED message did not do the trick, but I think it sent me in the right direction. Thanks for the help and let me know if you can think of anything else.

A Thready Question

I've been recently experimenting with threads and found that I got an error when i tried to pass a class member function as the Thread entry point (something about not converting void(void *) to void(__cdcl)(void *). I tried attaching the __cdcl (somethin like __cdcl anyway) to the function definition but it did not help. Is this possible and if not is there a way to have global functions access member variables (friend keyword??)?

Nish Nishant1-Nov-01 17:09

You cannot pass non-static functions as the thread proc.
But what you can do is to pass a pointer to your class's instance as the LPVOID parameter
Then you can cast the pointer to your class and use the members from the global function.

You can make the function as Static member of the class(instead of global class) and then pass it to thread function.

Deepak Khajuria

Nish Nishant1-Nov-01 20:48

But then he wont be able to access the non-static members

Nish

Deepak Khajuria1-Nov-01 21:02

Deepak Khajuria

Yes, he has to pass the instance of the class as parameter,or something similar.

But the main difference is that the static function of the class has full access to the class, where as global function cannot access the protected/private members.

Deepak Khajuria

Nish Nishant1-Nov-01 21:10

He can always call the static functions of his class from his global function anyway. Thus he can also access all static members (via the static function, of course)
