global variable access Qs

Hi guys,

I've a declared bunch of global variables in
CMyClass
{

}

and I want to access them in CMyOtherClass. How do I do that?

Can I use extern? how about static? The compiler still warns me that I've "undeclared identifier" in CMyOtherClass when use those two keywords.

Help? Smile | :)

Then only in the .H file I should've declared the global variables, is that right?

Thanks.

I was thinking that you meant member variable because you said they were in CMyClass. If they are global variables, then they should be declared in 'MyClass.cpp' and extern in 'MyOtherClass.cpp'.

Let me answer my own question: FYI::

Put the global variables in the .h files and include the .h. and it'll be visiable to any class which includes .h.

You want to insert text at the bottom of the richedit control?

CHARRANGE cr;
cr.cpMax = LONG_MAX;
cr.cpMin = LONG_MAX;
richedit.SetSel( cr );  // move selection to the bottom
richedit.ReplaceSel( (LPCSTR)string ); // insert your text

// force the rich edit to scroll to the bottom
richedit.SendMessage( SB_BOTTOM, NULL, NULL );

Hi All,
I want to use ADSI's IADsDomain Interface in my application to enable the password attribute- password complexity.The problem I'm facing is that I'm not able to set the ADsGetObject method's parameter 1 correctly.Hence unable to bind to the object.For convineince I'm giving the statement I'm including in my application.

hr = ADsGetObject(L"WinNT:",IID_IADsDomain,(void**)&pDomain);

Since I'm connecting to my own system hence I'm using the WinNT: parameter.
Can anybody help me out.

setting udp winsock source port

Kuniva28-Sep-02 0:05

Hi.
I have a program that creates a datagram(udp) socket and sends something using sendto(). But windows/winsock seems to determine the source port it uses (which varies somewhere around 1100). But i need it to be sent from an exact source port. I tried to play around with the bind() function and the sockaddr_in structure but no luck so far. Does anyone know how to do this?
Any help would be very much appreciated. Thank you.

Try this:

SOCKADDR_IN sockAddr;
memset(&sockAddr,0,sizeof(sockAddr));

sockAddr.sin_family = AF_INET;
sockAddr.sin_addr.s_addr = inet_addr(lpszSocketAddress);
sockAddr.sin_port = htons((u_short)nSocketPort); // nSocketPort is the desired port

bind(socket, &sockAddr, sizeof(sockAddr);

hope this helps

Have you even tried googling for "CRC polynomial"?

Do a search for Control Spy on MSDN. Control Spy is articles and source code showing how to work with toolbars and other win32 common controls.

Ehhh, yes? The WWW world is full of examples of this. Not to mention you get it "for free" (not really, but close enough for your use) from MFC. It's all documented and with lots of examples.

Windows hooks enumeration

27-Sep-02 20:39

I am sorry if I had chosen the invalid thread for my question.
I have a problem - I need to get the handles of all installed WH_KEYABOARD hooks in my system. Currently I need this for Win95/98/Me. I just know, that hooks are the USER objects, so there is a way to enumerate them. But MSDN does't say anything.
And one more question - is it possible to clear the hook chain retaining just mine and system - delete just user-installed?
I'll appriciate any suggestions and any help.
Thanks.
