hi i am tryingto build astatic library. and while i build i get this fatal error, kindly help me rectify this.
fatal error C1083: Cannot open include file: 'BasicHashTable.hh': No such file or directory
|
|
|
|
|
if this is a C# question, it's in the wrong forum.
if it's a C++ question, then you have to either tell the compiler where to find BasicHashTable.hh or, put BasicHashTable.hh in a place where the compiler is already looking.

Assuming your controls are in a dialog box: If you are using Win32 then you may call SendDlgItemMessage (with WM_GETTEXT or WM_SETTEXT, depending on your needs).
In a similar way you may use MFC's CWnd::SendDlgItemMessage.

CWnd::SendDlgItemMessage,
i have no idia if you give example, it is very helpful to me.
|
|
|
|

Inside a method of your window class (the parent window of your buttons) call, for instance:
SendDlgItemMessage(5000, WM_SETTEXT, 0 , (LPARAM) _T("BUTTON 0"));

If you post your (relevant) code may be I can tell you how to modify it.

ON_COMMAND_RANGE(5000,5100,OnButtonRange)
void CTest::OnShowWindow(BOOL bShow, UINT nStatus)
{
CDialog::OnShowWindow(bShow, nStatus);
CButton* m_btDynamic;
CString csText;
int k=0;
for(int i=0;i<5;i++)
{
m_btDynamic = new CButton();
csText.Format(L"Button %d",i+1);
m_btDynamic->Create(csText, BS_FLAT|WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON|BS_ICON,
CRect(10+k ,10+k,60+k,60+k),this, 5000+i);
k=k+30;
}
}
void CTest::OnButtonRange(UINT nIDforControl)
{
int iSelectedControlID;
iSelectedControlID = nIDforControl;
// here i want button caption
}
Where i should use SendDlgItemMessage()

Well, you already set the caption for you button with known values, so what's your need now?
BTW I suggest you to maintain the CButton pointers in a member variable:
in class declaration:
CButton * m_btDynamic[5];
then, in you function you may do
void CTest::OnShowWindow(BOOL bShow, UINT nStatus)
{
CDialog::OnShowWindow(bShow, nStatus);
CString csText;
int k=0;
for(int i=0;i<5;i++)
{
m_btDynamic[i] = new CButton();
csText.Format(L"Button %d",i+1);
m_btDynamic[i]->Create(csText,BS_FLAT|WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON|BS_ICON,
CRect(10+k ,10+k,60+k,60+k),this, 5000+i);
k=k+30;
}
}
so that whenever you need to access the caption of, say, third button, you may call
m_btDynamic[2]->GetWindowText();

thanks CPallini,
this is not exact code i have posted.
in my actual code i have created 100 buttons, same way as u told. but the problem is if user right click on any button i want that caption.
|

You may do this way (in your event handler):
CButton * pClickedButton = (CButton *) GetDlgItem( id );
CString sClickedCaption = pClickedButton->GetWindowText();

It's GetWindowText, not GetText.
But if you look at the documentation for CWnd on msdn, you can see the details for yourself too.
Good luck!
Iain.

Hi I'm making a simple drawing program I used offset to set up a specific drawing.
The picture drawn with offset moves on the screen when i draw another picture everything drawn with this function moves by one pixel permanently on the screen. Cant find source of this problem.
It is an MFC aplication.
CS2::CS2(CPoint Start, CPoint End, COLORREF aColor)
{
m_PunktP = Start;
m_PunktD = End;
m_Color = aColor;
m_Pen = 1;
m_EnclRect = CRect(Start, End);
m_EnclRect.NormalizeRect();
}
CS2::~CS2(void)
{
}
void CS2::Draw(CDC* pDC)
{
CPen aPen;
POINT pt;
if(!aPen.CreatePen(PS_SOLID, m_Pen, m_Color))
{
AfxMessageBox(_T("Pen creation failed"), MB_OK);
AfxAbort();
}
CPen* pOldPen = pDC->SelectObject(&aPen);
pDC->MoveTo(m_PunktP);
pt.x = 0;
pt.y = 63;
m_PunktP.Offset(pt);
pDC->LineTo(m_PunktP);
[...]
pt.x = 0;
pt.y = -13;
m_PunktP.Offset(pt);
pDC->LineTo(m_PunktP);
pt.x = -32;
pt.y = 13;
m_PunktP.Offset(pt);
pDC->LineTo(m_PunktP);
pDC->SelectObject(pOldPen);
}

Please post code snippets using the code block button.
Could you please elaborate a bit?
(I'm not sure I got you) You're trying to draw shapes at the mouse pointer position and are you in trouble because of too many drawings take place?

No it moves pemanently torwards lower right when I draw more pictures theyre just slipping off screen 
|
|

|

That's probably because your 'offsetting' m_PunktP on every Draw call (albeit you aren't actually using a 1-pixel offset).
What do you intend to do, instead?

I think the problem are those lines m_PunktP.Offset(pt);.
You are changing the value of this point with every call and because its a member variable this value is also changed with every call to Draw.
(I hope I understood your problem in the right way, not sure about this.)

Ok thanks a lot guys I got it I was drawing with coordinates it was enough to make a drawing close with -1 coordiante if starting position was (x,y) the total ending position had to be (x-1, y-1); else it moved by the difrence.
thank again cya

Hello everybody,
I have a class with one member function and member variable declared in the header file.
I have compiled my code and created obj file.
When I opened the obj file I saw the decorated member function in the obj file.
But I couldn't find the member variable in the obj file.
I want to know whether compiler keep the member declared in my class in obj file or not?
Please help me.
