Re: Value of a pointer of function

Oh, OK, you just want a pointer to point at a member function.

class CBase
{
public:
  void func()
    {
    printf("Hello, VFunction.\n");
    }
};
 
int main()
{
CBase obj, *pobj = &obj;
void (CBase::*pBaseMethod)() = CBase::func;  // pBaseMethod now points at the member function.
 
  obj.*pBaseMethod();  // .* for plain objects
  pobj->*pBaseMethod();  // ->* for pointers to objects.
}

The .* or ->* operator dereferences the function pointer.

Haaaa... thank you again. but what i really want to know is how the virtual pointer and the virtual function table work inside the class.(actually, virtual pointer is inside the class, virtual function table is not)

Use CLSIDFromProgID. In this case, the ProgID is the Name of the interface.
e.g.

[ccode]
CLSID ID;
CString strProgID = "Program.Interface";
HRESULT hr = CLSIDFromProgID( strProgID .AllocSysString(), &ID); // GUID is in ID if successful.

[/ccode]

Hope this helps,
Bill

Not that I am aware of.
Basically you'll need to enumerate all the keys and then enumerate all the values.
Even if you find a class, that's all what even the class would do for you.

I recommend Joe Newcomer's class if you dont want to do the enumerating and querying usign API

Floating text (like tooltip) in client area

I've check everywhere I can, but how do I generate a small floating text display when the mouse cursor rest for a while over the client area?
Just like when you rest the mouse cursor over a variable in VC++, its class or type is displayed in a small info box much like the tooltip. Confused | :confused:

Open a Modal Dialog as Hidden

Yes, use DoModal
In the InitDialog use ShowWindow with SW_HIDE.

Hello, the codegurus around the world.

Are you sure that ShowWindow (SW_HIDE) works?

I think that the controls on the dailog is hidden by ShowWindow (SW_HIDE)
, but the dialog isn't hidden by ShowWindow(SW_HIDE) in OnInitDialog().

In fact, I try to do this by myself, but this didn't work.
So, I use MoveWindow, and use the size of the dialog as zero.
(look like hidden Roll eyes | :rolleyes:

)

Or, you are sure. Confused | :confused:

Have a nice day!

You are correct. For a modal dialog putting ShowWindow(SW_HIDE) in the OnInitDialog won't have the expected effect. But you can try this. Put this in the OnInitDialog.

SetTimer(5000,5000,0);
You can change the 5 seconds to 3 seconds or even 1 second. But don't make it lesser than that, because we need to make sure the dialog has comeup on screen.

Now in the OnTimer(UINT nIDEvent) do this :-

if(nIDEvent==5000)
ShowWindow(SW_HIDE);
You might want to use KillTimer to prevent the timer function being activated repeatedly and meaninglessly.

But mind you, once you've hidden the window, the user cannot do anything to it. I hope you are sure, this is what you wanna do, because I see no reason why anyone would want to hide their modal dialog.

Hello, the codegurus around the world.;)

Thanks, BusterBoy.

However, I have already implemented this kind of code in my project.
In my case, I use Timer to show the dialog hidden by MoveWindow
in OnInitDialog(). Cool | :cool:

In fact, if the other ppl succeed in for the dialog hiding
by ShowWindow (SW_HIDE) in OnInitDialog(), I must consider that my code
may be something wrong with others in OnInitDialog(). Confused | :confused:

Have a nice day!

A hidden modal dialog will make your app unusable, since modal means the parent window is disabled. So you'll end up with a disabled main window and no way to interact with the dialog.

Why I need this

sanskypotov25-Nov-01 18:08

sanskypotov

25-Nov-01 18:08

Actually the whole setup is like this
I am using Threads in a DLL
So the first window( Modal ) dialog is in a DLL opens
and creates thread which contains another window.
Now this window keeps sending messages to the Main
window and when the 2nd window completes it's task
it send message to the parent window to close everything.
So I have used a Timer in the main window to check
whether the 2nd window ( Modal child ) is closed, so a
flag informs the Main window that the child is closed,
then the main window closes itself. I need that the
user should not see the main window.

One of the major problem that I face is that the
Thread communication. I need that child window closes
itself and informs the Main or Parent window to close
itself. Timer was the only thing I could work out
If anyone has a better Idea , I would appreciate it.
Thanks

Hi !

I want to have a similar interface as the windows-explorer one, with a tree control on the left, a list on the right, with user-resizable width.

Anyone could give me some hints ? I tried to use a splitview application, derived from CListView, but how can I have a tree view on the left part of my app ?

Any help is welcome !

Thank you !!!

Use a splitter window.
Derive the left view from CTreeView and the right view from CListView.

Hi,

I'm developing an application that needs to be able to save reports in a variety of formats, namely HTML, Word and PDF formats. HTML is easy as its just a text file, Word is easy because of the automation, but i dont know how to handle the PDF format. Is there a tool that can convert HTML files to PDF, or Word files to PDF, or is there another way around this. I know that Acrobat 5.0 comes with this ability but i need something thats 'free' to distribute.

Cheers in advance,

Andy.
