Yep, that's what I have in mind. The tricky part is when and where. Typically, you'd do your initialization work in either OnInitDialog or OnSetActive, but focus is set to the first control in the tab order after both of these have returned.

trying to create a CFrameWnd frame window as a child of a mainframe ( like other child frame windows and views )
m_pChildGridFrame->LoadFrame( ID_RESOURCE, WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE, this );
The frame is created, but not at the same level as the other windows, I can't put my other views on top of that one.
I'm pretty sure the "parent window" is not the good one.
Thanks.

Won't you have to add the WS_CHILD style?

Hello, a while ago I planned on programming with c/c++. The problem was the compiler. Now I have one but when I make just a simple program like: "hello world" the DOS screen will apear for just very short. Then it closes itself. I was thinking maybe it was logical because you just tell him to show "hello world" and then it quits by itself. So I made a program were you had to put 2 numbers in variables. I entered 2 numbers and pressed ENTER and the same thing happens. Does anyone know how to solve this?

Hello!
Try to use getch() or _getch() at the end of the code.
This application quits, becuase there is no loop. So either solution is to create a loop.

|
|
Try using getch() after your final input

it's not a problem...
If you run your application from VC with Ctrl+F5 you will see the message, and then you must to press a button to close it.
When you run your application for example in debug mode, the VC creates the console and close it when the app finish.
If you like, you can run your app from command line, and you will see when the app finish the cursor returns to the prompt...

I like to use this (at the very end of your program, before the return of the main function):
system("pause");
Actual Linux Penguins were harmed in the creation of this message.

or you can add a cin>> at the end like I do

Is it possbile to add controls to a CDialog based class at runtime? It was easy enough in MC++ with the controls property of a form. Is there something similar for CDialog? Thanks.

Hello!
Simply create required wnd class with parent set to the dialog and place it somewhere inside dialog (in order to see the control). See for example CEdit::Create(). Created window may have to be shown by CWnd::ShowWindow()
Tell me if you want more detailed description.

|

|

I sort of understand, but would appreciate a more detailed description, like how would I specify where in the dialog I want the control located (coordinates). Thanks again.

// CtesttestDlg message handlers
CEdit *pEdit = NULL;
BOOL CtesttestDlg::OnInitDialog()
{
CDialog::OnInitDialog();
pEdit = new CEdit;
pEdit->Create(WS_CHILD | WS_VISIBLE | WS_TABSTOP | WS_BORDER, CRect(10, 10, 100, 100), this, 10005);
pEdit->ShowWindow(SW_SHOW);
...
and I know, I know...it should not be a global variable, and should be deleted somewhere, but this is only a sample :P

Makes sense, I'll give it a go. Thanks for the help.

I've worked function pointers for years, mostly in C.
But I was wondering, since a reference is just a deference pointer, is there such a thing as funtion refernce in C++?
I do not remember reading about such a thing.

that's normal, functions references don't exist...
i'm sorry to announce to you that the function pointer is not dead !!!
remember that reference is not only a "dereferenced pointer"...

Ya, I did not think so.

Actualy they are, C++ just hides that fact (or has some thing changed?).
The first C++ complier was actualy a C complier with a C++ front end that converted the C++ code to C code before complation. Therefore, since C does not have direct references, all references where dereferenced pointers.;)

C++ defines references to functions, for instance:
typedef void (& fun_ref)(int);
...
void foo(int x)
{
...
}
...
fun_ref f=foo;Interestingly enough, there are no references to member functions. I don't know the exact reason, probably it is just an overlook.

Thank you very much! That makes logical since to me. Of cource I was hopping that you could specify references to member funtions.
When I think of how references are normaly assigned (as you showed), I can see why there are no references to member functions.

Really? I do not see any fundamental reason why references to member functions cannot exist, they'd be used like this:
struct A
{
void foo(int);
void bar(int);
};
typedef void (A::& mem_fun_ref)(int);
...
mem_fun_ref f=A::foo;
A a;
a.f(5);But anyway the sad reality is that references to member functions do not exist in C++. I've googled a bit for a plausible explanation, and found none

Have you asked Stroustrup or the ISO C++ Committee about it?
How did they say?

I want to prevent "Screen Capture".
I tried to prevent the message "Print screen" Key.
But "Capture Software" and Original Destktop Capture Software could capture.
So,I noticed mouse cursor wasn't captured.
I tried to draw object like drawing mouse-pointer.
But failed....I couldn't predict mouse-pointer drawing process.
Do you think of the solution method ?
"mouse-pointer drawing process"
or other method ?

When terraserver.com was a free service and all the 1 meter images were available it used to have this feature. It would use an ActiveX control inside IE to draw the images, but if you tried to "PrintScreen" and paste in Paint you would get their logo!
They accomplished this by drawing directly to video memory perhaps using DirectX.

Thank you for the reply.
But I could paste.Am I wrong?
>They accomplished this by drawing directly to video memory perhaps using >DirectX.
Sure.I tried by using DirectX.
But I don't want to use as special a thing-"special API." as possible.
Can we draw object like drawing mouse pointer?
