"how to set background color ?"

Hi ,

U can handle WM_CTLCOLORDLG to change the background color of the dialog.

In the link u have given, the code is not returning the handle to the new bursh u want to set for the dialog. See what msdn says

"OnCtlColor must return a handle to the brush that is to be used for painting the control background".

In the code u r returning the default brush handle. so that may the problem of not changineg the background color.

and change your code like this

<br />
if(nCtlColor == CTLCOLOR_DLG)<br />
	{<br />
		hbr = CreateSolidBrush(RGB(2,22,222));<br />
	}<br />

thanks

Dear Nitheesh,

I am still not able to change the background color after I tried the code below. As I'm a beginner of c++, would you please point out the deficit or improper use of code. Thank you very much!

HBRUSH CMyAppView::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CScrollView::OnCtlColor(pDC, pWnd, nCtlColor);

if(nCtlColor == CTLCOLOR_DLG)
{
hbr = CreateSolidBrush(RGB(2,22,222));
}
return hbr;
}

Cheers,
john

Hi All,
I am enumerating the network adapters by using the GetAdaptersInfo() API. But, I am not able to distinguish between the ethernet and wireless network as both the adapters are having the type as MIB_IF_TYPE_ETHERNET. Does anyone have an idea?

Thank you,
AJ

Looking at the documentation on MSDN GetAdaptersInfo( ) doesn't return that much detail and has been superseded by GetAdaptersAddresses[^] as of Windows XP, however even that only looks like it will differentiate between wired and wireless on Vista and not XP.

Yes it helps for system windows..

in my SDI appln,

CWnd* pWnd = CMainFrame::GetActiveWindow();

pWnd-> doesnt have setsyscolor or getsyscolor.

how could i get these functions to my CMainframe (constructor or create)

i NEED TO CHANGE ACTIVECAPTION/INACTIVECAPTION Colors.

thanks

It's a api function, just call ::GetSysColor/::SetSysColor.
Use parameters like:

COLOR_GRADIENTACTIVECAPTION<br />
COLOR_GRADIENTINACTIVECAPTION

AFAIK, if you handle OnNcPaint, you need to do everything (redraw everything )

(but I might be wrong).

u r right ..if i handle NCPAINT i got to redraw each and evrything in title bar on my own.
Instead iam looking for some solution from which i can change color of Title bar without disturbing caption text,icon,standard buttons.

Create a button whose id is ID_FILE_NEW, not be processed by CWinApp::OnFileNew

13-Apr-08 20:02

yes i searched through and got one MDI application who does exactly what i wanted but he paints customised title bar on exhisting default bar by using subclass technique by Paul DiLascia(MS journal).

my client doesnt allow me to add custom class for this kind of need.

SDI, can't CMyApp::OnFileNew handle the the click message by the button?

int CMyView::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
  ...
  m_btnNew.Create(NULL,style,rcDummy,this,ID_FILE_NEW);
  m_btnNew.LoadBitmaps(IDB_NEW,IDB_NEW_DOWN);
}

thanks

No, I just created a button using ID_FILE_NEW.

Re: Create a button whose id is ID_FILE_NEW, not be processed by CWinApp::OnFileNew

11-Apr-08 4:29

hi,

then u have to map the WM_COMMAND for the Button Id in following way. ON_COMMAND(ID_FILE_NEW,CWinApp::OnFileNew)

thanks

Re: Create a button whose id is ID_FILE_NEW, not be processed by CWinApp::OnFileNew

11-Apr-08 5:22

It's there in CMyWinApp as part o fthe framework.
I don't why the message is not pumped there.

Re: Create a button whose id is ID_FILE_NEW, not be processed by CWinApp::OnFileNew

11-Apr-08 6:45

Hi,

this is because the BN_CLICKED message is posted into the Parent Windows message queue. that is why the message is not getting into CWinApp.

thanks

Nitheesh.

Re: Create a button whose id is ID_FILE_NEW, not be processed by CWinApp::OnFileNew

11-Apr-08 7:09

But CWinApp::OnFileNew is a protected member function, so I couldn't add the following line to CMyView:

ON_COMMAND(ID_FILE_NEW,CWinApp::OnFileNew);

any quick way?
