Hi,

How can I add a circle on top of the bitmap image?
I added the following code to draw a rectangle on top of bitmap image. But rectangle is underneath of the BMP image.

CCLientDC pDC(this);
pDC.MoveTo(100,100);
pDC.Rectangle(20,20,30,30);

Please help me.

thanks in advance

is it just for drawing purpose? or do you want to save it to the file?

it is easy to place a rectangle over bitmap. first draw teh bitmap using BitBlt or StretchBlt, then draw the rectangle over it. it will work

Hi Sarath,

Following is the code ... I'm new to VC++/MFC.

m_hBmpNew = (HBITMAP) LoadImage(AfxGetInstanceHandle(),
"bng4.bmp",IMAGE_BITMAP,
0, // desired width
0, // desired height
LR_LOADFROMFILE);

if( m_hBmpNew == NULL ){
AfxMessageBox("Load Image Failed");}

// put the HBITMAP info into the CBitmap (but not the bitmap itself)
else{
m_st1.GetClientRect( &rectStaticClient );
rectStaticClient.NormalizeRect();
m_size.cx=rectStaticClient.Size().cx;
m_size.cy=rectStaticClient.Size().cy;
m_size.cx = rectStaticClient.Width(); // zero based
m_size.cy = rectStaticClient.Height(); // zero based
// Convert to screen coordinates using static as base,
// then to DIALOG (instead of static) client coords
// using dialog as base
m_st1.ClientToScreen( &rectStaticClient );
ScreenToClient( &rectStaticClient);
InvalidateRect(&rectStaticClient);

// Added to draw a rectangle
CCLientDC pDC(this);
pDC.MoveTo(100,100);
pDC.Rectangle(100,100,110,110);

i'm loading bitmap image using LoadImage(). Rectangle image is coming underneath of the bitmap image.

Thanks & regards
Ravi

	CPaintDC pDC(this); // device context for painting<br />
	CRect     Rect;<br />
	GetWindowRect(Rect);<br />
	ScreenToClient(Rect);<br />
m_Image.BitBlt(pDC.m_hDC,Rect.left,Rect.top,Rect.right,Rect.bottom,0,0);<br />
  pDC.MoveTo(100,100);<br />
  pDC.Rectangle(100,100,210,210); <br />

either you can use XMLHTTP class (easiest) or elase use WinInet APIs.

Hi,
I'm writing an 3D editor and I'm trying to get my viewport arrangement running.

I thought I should create it like this:

CMainWnd (CWnd)
-- CViewport x 4 (CView)
---- CViewportControl (CFormView)
---- CCameraView (CView. My CD3D9View actually..)

I then place four CViewport in a splitter window. The problem is that i don't know how to place the CViewportControl FormView inside the CViewport view. For some reason I had no problems with creating the CCameraView but the CFormView is a b**ch... I successfully added it with an odd hack but whenever I clicked it the came crashed with an odd assertion. How do I create it when there is no "Create()"?

u really need a view inside a view. if so it has to be in a splitter again. thats teh right approch. or else go for a dockable style dialog inside a view.

what do u think?

The thing is that I'm a total newbie with MFC so I don't really know how to do it. The CViewport "view" doesn't have to be a view I suppose, only the CCameraView has to be a view since it's the only part of the "framework" that actually display data from the document. What class should i derive CViewport from instead and how do I add controls (a combo and a checkbox) to a dockable toolbar?

Could anyone guide me how I should structure the classes to make a viewport window like the ones you see in 3dsmax, maya etc.

I hope my questions doesn't sound too confusing, though I AM really confused about MFC. Whatever I do seems to cause assertions and trace errors or odd memory exceptions Frown | :(

I just realized after typing my response that the creation of the sub-view wasn't the problem. The problem was with creating the "control panel" inside each viewport from my dialog resource. How the heck do I do that? Big Grin | :-D
