If you're using \n for new line try using \r\n instead.

strCSV = L"|" + strCSV+ char(13) + char(10);
csvFile.Write(strCSV,strCSV.GetLength());

that is how i inserting.

Try it

CString cszOut;
cszOut.Format(_T("|%s\r\n"), strCSV);
csvFile.Write(cszOut, cszOut.GetLength() * sizeof(TCHAR));

virtual void BeHappy() = 0;

Hello everybody,

in my MDI application, I use a theApp.MainFrame->SetRedraw(FALSE); to freeze the mainframe during the child window creation, to avoid creation flickering.

When I close the child, I use the same technique.
If the user hits the ESC key, I make the theApp.MainFrame->SetRedraw(FALSE); then I close the child.

This technique works great for the creation of the child, but at the destruction it makes a big error.
The mainframe seems transparent for all kind of inputs.
The mainframe is correctly redrawn but mouse and key inputs are directly send to the window "under" my application (Visual Studio when i debug, for example) and this other window gets the focus.

Has anyone an idea?

Big thanks

Does the effect (lost focus) exist
when you do not set anything at the child closing ? Smile | :)

No, then all is working correctly

That's strange to me Frown | :(

Could you try it ? Smile | :)

// ESC scope
{
  CWnd* pcWnd = AfxGetMainWnd();
  pcWnd->LockWindowUpdate();
  // Close a child here
...
  pcWnd->UnlockWindowUpdate();
}

virtual void BeHappy() = 0;

I removed the LockWindowUpdate / SetRedraw(FALSE) (both won't work correctly) out of the closing-traitement.

The first childwnd is created nicely, but if I open a second one, than the SetRedraw doesn't affect.
I see the new frame a half-second on another position as the correct end-position.
That seems ugly Sigh | :sigh:

Before I used a GetDesktopWindow()->SetRedraw(FALSE) ... that worked great, but it's very risky.
If an error occurs, the Desktop-Window is never been redrawn correctly Unsure | :~

How would you fix this kind of workarround. Simply create a child window, which will be displayed only after all sub-controls are created and the their positions are well moved.

Big thanks Smile | :)

typecasting in std::vector type

1-Apr-10 4:26

Maybe, you could create the childs invisible (~WS_VISIBLE)
and then call ShowWindow(..) for them ? Smile | :)

Hi,
I have using a source code representing a class hierarchical like the following:

class c1
{...};
class c2 : public c1
{...};

now there is a method in another class which has argument like:

void Func1(vector<c1*>& vC1);

How could I pass the following vC2 to this method

vector<c2*> vC2;

Is there any way to typecast the vector<c2*> to vector<c1*>?

Eugen Podsypalnikov1-Apr-10 0:12

You could try to declare your function as:

void Func1(vector<c1*>* pC1Vector);

and then pass a casted pointer Blush | :O

{
  vectror<c2*> vC2;
...
  Func1((vector<c1*>*) &vC2);
}

virtual void BeHappy() = 0;

Maybe, it would be better (possible)
to collect your c2-pointers to a vector<c1*> vC1; instead ? Smile | :)

Short answer - no. Just because c2 is convertible to c1 doesn't mean that types dependent on c2 (like vector in this case) can be converted to equivalent types dependent on c1.

Create the colored brush using CreateSolidBrush.
Use SelectObject to select the brush into the device context used in the first parameter of Ellipse.

Ellipse has 4 parameters.X,y,width,height only.

To fill the Ellipse when you draw it, you need first to create a Brush of the correct colour and then load it into the current Device Context. Then when you call the Ellipse function it will fill it with the correct colour. Smile | :)

Something like this ....

CBrush brMine;
CBrush *pOldBrush = NULL;
brMine.CreateSolidBrush(crRed);
pOldBrush = pDC->SelectObject(&brRed);

Then draw your Ellipse. Smile | :)

Try this...

   CDC *pDC = GetDC();
CRect rect;
GetClientRect(rect);
CBrush brush;
brush.CreateSolidBrush(RGB(255,0,0));
CBrush *pOldBrush= pDC->SelectObject(&brush);
pDC->Ellipse(rect);
pDC->SelectObject(pOldBrush);
::ReleaseDC(m_hWnd,pDC->m_hDC );
