When you add new menu item to SDI/MDI MFC application it is disabled in run-time untill you write message handler for this item.

Maybe it has to do with command update handlers. Have you ON_COMMAND_UPDATE_UI handlers for the new commands in the additional menu bar? (I'm asuming you already have ON_COMMAND handlers for them)

Also you might find interesting to have a look at the flag

<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmfc98/html/_mfc_cframewnd.3a3a.m_bautomenuenable.asp">CFrameWnd::m_bAutoMenuEnable</a>

, which gives you control over this kind of things.

If I'm understanding your question, you should write something like this on your command handler:

CYourDialog dlg;
dlg.DoModal();

}

but this error appear!!
error C2065: 'login' : undeclared identifier
error C2146: syntax error : missing ';' before identifier 'dlg'
error C2065: 'dlg' : undeclared identifier
error C2228: left of '.DoModal' must have class/struct/union type

mmmh... What is that login? It is a CDialog class, right? Then in your project you'll see a .cpp and a .h (possibly login.h) files associated with the class. Include this line at the beggining of the file where the error is:

#include "login.h" // or whatever the header file for the class is named

You know, this is pretty basic C/C++ stuff. Maybe you should spend some time reading some C/C++ primer to get the fundamentals learnt. Do a search on Internet, there must be plenty of tutorials.

I have download the remote control code here from CP and can't get it to work (any more)!!

The problem is that it can't connect to the server over the LAN!!
Another Winsock app works just fine and it uses CAsyncSocket class...

I know this should be impossible for you to say whats wrong without code example. But you perhaps know something that I don't know...

Joaquín M López Muñoz wrote:
The error is descriptive enough... seems like the server is not running properly. Try issuing a telnet your_server_ip port where port is the port number used by the app to determine whether the server is running or not.

Yes, I've done that and the Telnet client came up and was connected to the server... so... is my LAN not working properly?

Do you remember this message ?

You did a telnet aaa.bbb.ccc.ddd 5150? Please note the 5150, which is the TCP port used by the app (I peeked inside the code). A normal telnet is no useful test.

Wll, I've used 5729 instead of 5150 because I've read in the Winsock FAQ that 5150 was a reserved port number so I change but now when I changed back it works... weird...

Well well...

CListCtrl Question

Paresh Solanki31-Jan-02 0:50

31-Jan-02 0:50

How can I syncronise (..ize for you yanks) the column widths on two CListCtrl objects?

I have an app with two CList objects aligned vertically. I am already processing the OnNotify() to update the data in list2 depending on the selected row in list1.

When the column width is adjusted in list1, I would like list2 to update it's column to the same width. However I can't find the notification code in MSDN.

Any ideas?

You have to handle the message NK_ENDTRACK, which is sent when a column has been re-sized. The header control can be a bit funny in NT and not send the message with the correct control id (it has it set to 0). Here is some code which I have used in the past:

// in your OnInitDialog etc
	m_Methods.GetHeaderCtrl()->SetDlgCtrlID(m_Methods.GetDlgCtrlID());	

void CSamplesFloat::OnEndtrackMethodList(NMHDR* pNMHDR, LRESULT* pResult) 
{
	//HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR;
	// TODO: Add your control notification handler code here
	CHeaderCtrl* pHeaderCtrl = m_Methods.GetHeaderCtrl();
	if (pHeaderCtrl != NULL)
		{
		int  nColumnCount = pHeaderCtrl->GetItemCount();
		int	width ;
		for (int i = 0 ; i < nColumnCount ; i++)
			{
			width = m_Methods.GetColumnWidth(i) ;
			m_OtherCtrl.SetColumnWidth(i, width) ;
			}
		}
	*pResult = 0;
}

You just need to map the HDN_ENDTRACk for both list controls, and get one to size the columns of the other in each function.

Unicode in combobox

Hi,
I am reading unicode text from an Access database and want to put it in a combobox. The problem is that the text in the combobox appears to be plain ASCII. If I copy the text from the combobox and paste it into Word or so, I see the correct text again? Confused | :confused:

What should I do to get the unicode text displayed correctly, or is this "behavior by design"?

Hello, I have doubts about MFC7.0:

where can I get it?, is it free? do I have to buy it?

is used in order to get the graphical possibilies of XP and in order to get improved MFC controls and classes?

where can I get informed about that?

As always thank you very much...

I think if you install visual studio.net you can get it.And of cource it is not free(poor microsoft Blush | :O

)
Also if you want xp visualization in MFC6 or later for all platform check this:

How can I get a rotated region?

How can I get a rotated standard region(such as: ellise region, roundrect region)?

HRGN hRgn = CreateRectRgn(0,0,220,120);
DWORD size = GetRegionData( hRgn, 1, NULL);

RGNDATA *pData = (RGNDATA*)GlobalAlloc(GMEM_FIXED|GMEM_MOVEABLE,size);
GetRegionData(hRgn, size,pData);

double a = 0.5; // 0
xform.eM11 = (float)cos(a);
xform.eM12 = (float)sin(a);
xform.eM21 = -xform.eM12;
xform.eM22 = xform.eM11;
xform.eDx = 0;
xform.eDy = 0;

HRGN hNewRgn = ExtCreateRegion(&xform,pData->rdh.nRgnSize,pData);
// failure! why ?

GlobalFree(pData);
DeleteObject(hRgn);

DeleteObject(hNewRgn);

Thank you very much!

Try with

thanl: Joaquín M López Muñoz, now, I can get the rotated region!

the modify codes:

DWORD size = GetRegionData(hRgn, sizeof(RGNDATA), NULL);

RGNDATA *pData = (RGNDATA*)GlobalAlloc(GMEM_FIXED|GMEM_MOVEABLE,size);
GetRegionData(hRgn, size,pData);

a = 0.5; // 0
xform.eM11 = (float)cos(a);
xform.eM12 = (float)sin(a);
xform.eM21 = -xform.eM12;
xform.eM22 = xform.eM11;
xform.eDx = 0;
xform.eDy = 0;

HRGN hNewRgn = ExtCreateRegion(&xform,size,pData);

GlobalFree(pData);
DeleteObject(hRgn);
