I am a beginier with c++ and I was reading an article to make an XP button, and I don't know how to rename the CButton... can any one help?

Goto your dialog class header file (*.h) that contains the button you want to change to XP style.
It will be like this :
----------------------------------------
class CMyDialog : public CDialog
{
public:
.
.
CButton m_btn;
.
.
.
};
----------------------------------------

Change "CButton" word to your XP style button class name.
For example : CButton -> CXPButton.

Don't forget to include your XP style button class header before this dialog class header.
For example : #include "XPButton.h"

May be compiler can't find "definition" of constructor and destructor. Check your constructor and destructor for its completeness and validness declaration (usually in .h file) and definition (usually in .cpp file).

If it still can't help, confirm me.

I need to position my child window (formview) at position 0,0 each time it starts up. I tried the line of code below but it doesn't seem to do the trick.

SetWindowPos(NULL, 0, 0, -1, -1,SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE);

Without the code, its position is set at 0,0. But each time I open that same window up, it keeps changing to the next cascading position. How can I prevent this and have it start at position 0,0 each time?

Thanks!

You are supposed to do this by modifying the CREATESTRUCT in PreCreateWindow, so:

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
  if( !CFrameWnd::PreCreateWindow(cs) )
    return FALSE;
  // TODO: Modify the Window class or styles here by modifying
  //  the CREATESTRUCT cs

  cs.x = 0;
  cs.y = 0;

  return TRUE;
}

I inserted the above code and it still doesn't work. Each time I close the window and open it back up again, it moves to the next cascading position. I tried inserting similar code into BOOL CChildFrame::PreCreateWindow(CREATESTRUCT& cs) and it gives me the same result.

How do I import a class into a dll?

Hi,

I need to use a class that is outside of my DLL in my DLL. I've tried every way I know of, but I can't seem to accomplish it. I know you can export from a DLL, but can you import into a DLL? Unsure | :~

The outside class is not in another DLL, it's free-standing in the project.

I'm not very experienced with DLLs, so any help is greatly appreciated...Thanks!

If this means the class is in source-form, then just copy it over!

If it means it's part of an EXE, then Im afraid there is no easy way (if any) to import!

Hi Bikram

I would copy it over, but that class relies on other classes in the project. I can do it as a last resort and just copy all of the classes needed into the dll, but if I do that I may as well not use a dll and just put it all into the client project.

Thanks for your help!

Well, you needent really make a copy of the class and the classes it depends on...

Just add the class and the related classes to the VC++ file view..

So why not use a DLL? It's always better to do that, so that in future you have only one copy of the classes to maintain. With multiple copies, you, for example, fix a bug and you've got to fix the bug in all copies...

(Re)-allocation memory

Hi there,

Is it okay to allocate memory using the new operator and then to reallocate it (expand/shrink it) by using realloc?

...Or is there any better method that I should be thinking about?

Thanks,

David

No, new and realloc() are not compatible.

What would you advise me to do then? Should I just new a new portion of memory, memcpy the contents and then delete the old one?

What would you say?

new is an operator, while realloc() and memcpy() are functions. If you want to be able to use realloc(), use malloc() instead of the new operator. Memory allocated by malloc() should be freed by calling free().

You can but new is best used for allocating fixed-size memory blocks and objects.
