My dialog has the following options selected:

system menu

Thanks for the help

Add this code in your dialog's OnInitDialog() handler:

// Add "About..." menu item to system menu.

// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);

CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != NULL)
   {
     CString strAboutMenu;
     strAboutMenu.LoadString(IDS_ABOUTBOX);
     if (!strAboutMenu.IsEmpty())
        {
          pSysMenu->AppendMenu(MF_SEPARATOR);
          pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
        }
   }

IDM_ABOUTBOX is a string resource with the value "About MyApp..."

Thought I had this wipped, but I can't seem to intercept the OnSystemCommand.

How does the drop down menu on the system title bar get called and where is it located?

It's like it just magically does it on its own.

Differnance between MFC extension DL L and regular mfc dll?

Hi All,

I was wondering what would be the difference and why would I want to use either type. The application wizard let's me make a standard dll using mfc shared/static or an MFC extension dll.

Any clarification would be helpfull.

Cheers,
Clint

I'm using CButtonST(posted there too) and am trying to make my buttons transparent, but can't seem to get it to work. Because the controls under the button are more than one color I can't just make it the same color. Is there a way I can set the icons back ground color so it doesn't display it or any other way to get around this?

Thanks

Hi,
my name is Juan and I develop software since 1996 on Visual C++. Recently I try to decode the mouse protocol, so I develop a service and open one serial port and received this data, now I want to send this message from user side to kernel side, I mean, I do not want to do a driver I try to use a service. So, my problem now is how to send this information to kernel side in order to dispatch the data to the application on the user side.
I wait for any help.
Thank you so much.
Juan

There's a line counter add in on the site somewhere - probably the add-ins section.

Quite simple really...

UDP is like fire and forget, meaning that you do not need acknowledgement of the packet getting to its destination i.e. video streaming.

TCP/IP needs to have acknowledgements meaning you are guaranteed delivery.

I do not know of any tutorials, this was from my Cisco courses.

I doubt it. If you really don't want the new lines you will need to massage the returned text to get rid of them.

XML- XSLT

wimel7-Mar-03 0:04

Yes, it's possible. But, not that easy.

The format of a HTML file is the same of a XML file. They both use <something> as tags. With XML there are a lot of possibilities.

It all depends on what you want to do with the HTML-file. If you want to parse/change/edit take al look at the DOM-parser. Then it doesn't matter if the code looks like
<head>
</head>
or
<head></head>

Another possibility is using XSLT for reformatting you XML file.
Again, it's not that easy to start with.

I'm creating an ActiveX control, using MFC in C++, that will be inserted into IE, Word, and a custom app. I need to add a toolbar for the control that docks to the parent frame, when the control is inserted in the container.

I haven't been able to find any info about doing this.

Any help would be appreciated.

Thanks,

Printing a custom control

I have a custom control that i do all the drawing on. If i want to print the control can i just replace the DC with a DC i get from CPrintDialog?

This works but it prints reeeally small. How can i get it to print so it is the same size as on the screen?

your screen is probably at 96 DPI, but the printer is likely 300 or 600 DPI. so, it's drawing with the same number of dots, but the dots are much smaller. what you need to do is to set the printer DPI (in effect) to the same as your screen DPI.

you can do this by adjust the DC's extents (see SetViewportExtent and SetWindowExtent and maybe SetMappingMode).

this might work for you:

pDC->SetMapMode(MM_ISOTROPIC);
pDC->SetWindowExt(desiredDPI);
pDC->SetViewportExt(pDC->GetDeviceCaps(LOGPIXELSX), pDC->GetDeviceCaps(LOGPIXELSY));

What should the desiredDPI be? I tried 96 and it seems to work pretty good but it prints everything a little smaller than it should be.

I can play around with desiredDPI and get it to print almost exactly like it is on the screen but there's got to be a way to figure what this value should be?

The View pointer to modal dlg

ns6-Mar-03 7:19

6-Mar-03 7:19

For the modeless CDlg it goes in in Create(IDD_DLG, this). For the modal dlg, how do we send in the parent pointer? Would it have to be assigned to a member pointer of the dlg class of the parent type?

Like:

MyCDialog myDlg;

myDlg.m_dlgParentPointer = this;

myDlg.DoModal();

If GEtParent() is the way to go instead, why is that better?
