In 'Release mode'?? Unsure | :~

Yes, this is necessary in order to create a log file containing a stack trace in the event of a crash. I'm using PJN's CExceptionLogger[^] class.

You don't need to disable optimizations. Setting Program Database (/Zi) for the compiler and "generate debug info" for the linker, will do.

Yes, you can have debug info, even in release mode.

You need to disable optimization in order to make the exception logger generate accurate line numbers into your source code.

What was the error? Kind of makes it hard to narrow down to the problem without a little help.

That said.... b1.Create should be b1->Create

Error? What error?

Are you storing this b1 pointer somewhere else so as to delete it when it's no longer needed?

softtec wrote:

int no,i;
no=1;
i=0;
rect.SetRect(i+20,20,400,i+20);

no++;
i+=10;

You are setting rect as left=i+20, top=20, right=400, bottom=i+20.

Assuming that's inside some loop, in the first iteration (when i==0), that means width=380 (i.e.: 400-20) and height=0 (i.e.: 20-20). In the second iteration (i==10), that means width=370 (i.e.: 400-30) and height=10 (i.e.: 30-20). In each iteration, the width is 10 pixels less (starting from 380), and the height is 10 pixels more (starting from 0).

Variable b1 cant be a local variable .
This belaw sample work successful .

CButton *b1;

void Create()
{
b1=new CButton;
int no,i;
no=1;
i=0;
rect.SetRect(i+20,20,400,i+20);
b1.Create(name,WS_CHILD | WS_VISIBLE | BS_CHECKBOX | BS_AUTOCHECKBOX,rect,&m_Stat,no);
no++;
i+=10;
}

or

void Create()
{
static CButton *b1;
b1=new CButton;
int no,i;
no=1;
i=0;
rect.SetRect(i+20,20,400,i+20);
b1.Create(name,WS_CHILD | WS_VISIBLE | BS_CHECKBOX | BS_AUTOCHECKBOX,rect,&m_Stat,no);

CImg Problem

Hello All!

I am working on image processing and using the library CImg. Constructor of CImg is used to load the image file (.bmp etc)...
Problem is that when the destructor of CImg Object is called, it doesnt release the full memory.

e.g if i load an image of 225kb...CImg creates an object of 20kb and release 20 kb when destructor is called. 220kb are left unreferenced in the memory.

This is causing hell of problem as i want to process 10-15 images per second.

Plz help me in this regard.

Regards
Mubashir

Sounds like to me that CImg (note: I've not even looked at the code or doc...) expects your application to manage that part of it. Is there a way to explicitly release the image before destroying the object?

hiho@ll

for simple test environment i'm using the SimpleBrowser from codeproject which uses IWEbBrowser2 to make a "self-made" webbrowser
i know it's relatively easy to control html pages using post or get or to change the input field values
but can this be done with a flash site?
the problem:
i load a flash site from the internet, which has input fields and a form (all made in flash).
so how can i fill out the flash form and send it with webbrowser2?
because it's https i can't really sniffer which content is sent

any suggestions?
thxalot

about Coordinate Map Mode and compatible DC ???

Re: about Coordinate Map Mode and compatible DC ???

How to change the Coordinate Map Mode ,create a compatible DC used to draw ,then call bitblt() to show the picture?

my code in the following , But when I run it ,there is nothing to be showed!

void CTestSetMapModeView::OnLButtonDown(UINT nFlags, CPoint point)
{
CRect rect;
GetClientRect(rect);
CClientDC dc (this);

dc.SetMapMode (MM_ISOTROPIC);
dc.SetWindowExt (rect.Width (), -rect.Height ());
dc.SetViewportExt (rect.Width (), -rect.Height ());
dc.SetViewportOrg (point);

CDC memDC;
memDC.CreateCompatibleDC(&dc);
memDC.SetMapMode(MM_ISOTROPIC);
memDC.SetWindowExt(rect.Width(), -rect.Height());
memDC.SetViewportExt(rect.Width(), -rect.Height());
memDC.SetViewportOrg (point);

CBitmap bitmap,*pOldBitmap;
bitmap.CreateCompatibleBitmap(&dc,rect.Width(),rect.Height());
pOldBitmap=memDC.SelectObject(&bitmap);
memDC.BitBlt(-rect.Width()/2,rect.Height()/2,rect.Width(),rect.Height(),&dc,-rect.Width()/2,rect.Height()/2,SRCCOPY);

//draw some pictures
memDC.Ellipse(-50,50,50,-50);
memDC.Ellipse(-10,20,10,-20);

dc.BitBlt(-rect.Width()/2,rect.Height()/2,rect.Width(),rect.Height(),&memDC,-rect.Width()/2,rect.Height()/2,SRCCOPY );

memDC.SelectObject(pOldBitmap);
bitmap.DeleteObject();

CView::OnLButtonDown(nFlags, point);
}

Antonlio,

One thing I've found interesting about Windows Programming is the level of filtering Win32 does that is quite invisible. In this case, Win32 contains some code that says "ignore all drawing unless I need to draw..." Windows makes the decision to draw if the window is invalid. If you invalidate the target window, windows will fire an On Paint message. Adjust your code accordingly, and all will be well (at least you should see something on the screen).

Re: about Coordinate Map Mode and compatible DC ???

25-Jun-05 6:14

I think the problem in my case is the " coordinate map ".
I don't know When I excute the following codes:

CRect rect;
GetClientRect(rect);
CClientDC dc (this);

dc.SetMapMode (MM_ISOTROPIC);
dc.SetWindowExt (rect.Width (), -rect.Height ());
dc.SetViewportExt (rect.Width (), -rect.Height ());
dc.SetViewportOrg (point);

, Whether I should also change the memDC's coordinate map mode ,just like the following :
CDC memDC;
memDC.CreateCompatibleDC(&dc);
memDC.SetMapMode(MM_ISOTROPIC);
memDC.SetWindowExt(rect.Width(), -rect.Height());
memDC.SetViewportExt(rect.Width(), -rect.Height());
memDC.SetViewportOrg (point);

The aim of my case is to paint picture in the memory-DC (compatible DC) ,for preventing glitter when refresh(repaint)!
And I choose the maths coordinate mode not the MM_TEXT .That is X-axis ascending from left to righgt while Y-axis from bottom to top!

Antonlio,

My exposure to date with Win32 is through Windows CE, and Windows CE does not support the different mapping modes. I cannot comment further regarding that issue. I understand what you are doing - it's called double buffering and a host of other names. What I would do is divide and reduce the issue. Just add some code that slaps something silly onto the page in the default mode. If that doesn't show up, it isn't your scaling, it's what I mentioned earlier...
