Make it a child of the desktop, rather than your hidden dialog - IE pass NULL for it's parent window.

There should be an option in the New Project AppWizard for 'Win32 Static Library'.

Do you wish to change the background color of a control or a dialog or what? If your question is to change a buttons color search this website for subclassing buttons. Chris and alot of folks have written fine articles doing this.

Thanks you , but
Some problem:

whenever button I supply to my Dialog,
methid of button
virtual void DrawItem(LPDRAWITEMSTRUCT lpDIS);
- not called.

What prevents to do it?

May be some handler masks it ?

The button must be set as an Owner Draw button. This is a property of the button in the resource editor on the Styles tab.

821114 - MDI menus

hamidi23-Feb-04 0:17

hi i use LoadMenu after SetThreadLocale to bring up Hebrew menus and replace the English ones with them. the problem is that whenever i close all documents or open a new document when no doc is open the new menu is opened in English while the thread locale is set to Hebrew.
what's wrong?
i use the following method to change the current menu lang:

UINT getDocTemplateId(CDocTemplate* pDocTemplate)
{
// Helper class to extract the m_nIDResource member
class CHelperDocTemplate : public CDocTemplate
{
public:
CHelperDocTemplate():CDocTemplate(0, NULL, NULL, NULL){}
UINT GetResourceId(){return m_nIDResource;}
};
return ((CHelperDocTemplate*)pDocTemplate)->GetResourceId();
}

void CMainFrame::pr_changeLanguage(AeLanguage lang)
{
SetThreadLocale(MAKELCID(MAKELANGID((lang==langFarsi)?LANG_ARABIC:LANG_ENGLISH,SUBLANG_DEFAULT),SORT_DEFAULT));
CMDIChildWnd *pChildWnd=MDIGetActive();
HMENU hMenu=LoadMenu(NULL,MAKEINTRESOURCE(pChildWnd?getDocTemplateId(pChildWnd->GetActiveDocument()->GetDocTemplate()):m_nIDHelp));
DelayUpdateFrameMenu(hMenu);
}

thank u

Your best option would be to change which menu gets loaded into the CDocTemplate m_hMenuShared member variable. You already inherit CDocTempte, so call a function which destroys the exising english menu and loads in the hebrew one. Then you do not need to worry about switching the menus everytime a document is opened/closed. You can also do the same for CFrameWnd::m_hMenuDefault, which is the menu used when no document is open.

Dynamic create Dialogs

hey i have the following hard problem:

depending on menu selections in my sdi application, different dialogs should be open (non modal). Each of these dialogs has it's own class and resources. Is there a way when user select menu item "1" to open a specific dialog without using a switch and declaring all classes as membervariables.

My code:

iID is the selected item...

<.h> <br />
<br />
C/C++ Code: <br />
CDialog1 m_dialog1; <br />
CDialog2 m_dialog2; <br />
CDialog3 m_dialog3;<br />
 <br />
C/C++ Code:

.........

<.cpp> <br />
<br />
C/C++ Code: <br />
bool CreateMyDialog(int iID, ....) <br />
{ <br />
switch (iID) <br />
{ <br />
  case 1: <br />
     m_dialog1.create(IDD_DIALOG1,this); <br />
     m_dialog1.m_Data = "hello, Dialog1"; <br />
  case 2: <br />
     m_dialog2.create(IDD_DIALOG2,this); <br />
     m_dialog2.m_Data = "hello, Dialog2"; <br />
} <br />
return true; <br />
}

first, you would need a callback for each menu item; second, I think, that your dialog class variables should be class members in the parent class ( or other controller class ) since they are modeless ( non-modal), the variable must not be destroyed when leaving the callback function/method.

Hi!

I hace a problem. I'm using libpcap for linux and collecting packets from ip-tv. I know that one TS packet are 188 bytes and 7 of them can be put in a IP packet (1316 byte).

When I recieving the IP packet there are 1358 bytes, recieved and the first TS packet start at the 42 bytes (TS starts with 0x47) at the IP packet (1358-42 = 1316 correct), but after 188 bytes further there will be 0x47 again to indicate that there is beginning of a new TS packet, and further 188bytes there will be 0x47 again, but it is not.

Does someone know what is wrong?

my code:
...
while(1)
{
packet=pcap_next(handle, &header);//grab packet
printf("packet with length of %s", header.len);

for(counter=0; counter
