Hi,
You can create a process using CreateProcess and can set it size in STARTUP_INFO parameter.

see msdn for more details.

AFAIK it is not possible to show that exe insde your appliaction, unless it's a COM control (ActiveX or DLL). I'm not sure about this.

If the application is simple enough, you can wrap it in an ActiveX control and have it run inside that. Also, if the application exposes itself via COM (like the office components), you can have it appear on a dialog, but it won't look like the full application in most cases.

In the case of a notepad or wordpad what? what we can do with that?

Office system is completely developed as COM Components and many applications using it very well. that is what I said, we can't make inside as our control or part of our application unless it is an attachable manner.

Re: CListCtrl and Graphic

Do you mean to embed one dialog in another? You could (probably should) do so in the same application. In fact, you can glue the two dialogs together forever. To do it properly:

In the client area of your container dialog, create a child window (rectangle). Pass this child window as the paranet of your embeded dialog.

CListCtrl and Graphic

Hello,

I'm using a CListCtrl in a CListView to show my data and now I want my data to be shown in a grphical form (with rectangles, circles, lines and so on). For testing, I decided to do this on a right mouse double-click an I implemented the following:

void kstkoardwView::OnRButtonDblClk(UINT nFlags, CPoint point)
{
// TODO: Code für die Behandlungsroutine für Nachrichten hier einfügen und/oder Standard aufrufen
//Test for Graphik
CClientDC dc(this);
CListCtrl &listCtrl = GetListCtrl();
RECT rect;
for (int i = 0; i <= 6; i++)
{
listCtrl.DeleteColumn(0);
}

GetClientRect(&rect);
dc.Rectangle(rect.left, rect.bottom, rect.right, rect.top);
int b = (int) (100.0 * rand() / RAND_MAX);
dc.TextOut(point.x-100, point.y-100, "Hugo");
dc.Ellipse(point.x-b, point.y-b, point.x+b, point.y+b);
dc.Rectangle(point.x-b+100, point.y-b+100, point.x+b, point.y+b);
dc.Rectangle(10, rect.bottom, 20, rect.bottom-100);
dc.Rectangle(20, rect.bottom, 30, rect.bottom-75);
dc.Pie(100, 100, 150, 150, 300, 300, 250, 250);
dc.Draw3dRect(200,200,300,300,0,0);
CListView::OnRButtonDblClk(nFlags, point);
}

But following happens: First double-click = Columns are deleted - the gray header-row is still visible. Second doble-click = the rest is done and I see my drawing.

Can anyone tell me why and a solution? Or has anyone a better solution to make graphics from CListView-data?

Thanks, Gerhard

If I understand what you are trying to do correctly, you have some data displayed in a ListView and the user can select an option to display it in a different way?

That being the case, you are going about it the wrong way. You should be creating another view that displays the data the way you want it. When the user turns on that view, you display it. This article should help get you started after you write the code for your new view.

Thanks for your answer,

I'm using MDI and till now (at the beginning) I have already about 10 DocTemplates. So I hoped, I can make the graphic (for each of this templates) without making a new one.

But regardless of this your answer helped me. I recogniced, that I have only to make a new View (and use the old Doc).

Thanks, Gerhard

Creating a Bitmap from a Framegrabber Image

im797-Jul-06 3:41

7-Jul-06 3:41

Hello all,
i'm trying to display a Bitmap in a Picture Control. The picture is captured by a CMOS camera (gray), and all i have is a pointer to the image in the Framegrabber buffer. The problem is that i don't have a real bitmap in that buffer, just an array with pixel values. The technical support of the Framgrabber producer couldn't help me till now and i'm still waiting for thier reply Sigh | :sigh:

. I was trying to create a Bitmap manualy and fill in all the needed structures like BITMAPINFO and so on but nothing worked. Can you tell me how to construct a bitmap from an pixelarray, just knowing the lenght, width and that's it is gray scale picture.
I would be very greatfull for any kind of help!

I wish you a nice Weekend Smile | :)

Gray as in 8-bits per pixel? Did you set up the color table? Show how you're calling CreateDIBitmap and your input values (BITMAPINFO).

Hello all, hello hrfy and thanks for your answer Smile | :)

Yes it is 8-bits per pixel. I didn't set the color table. I just called CreateBitmap or DIBitmap passing width, length, the pointer to the pixel array and so on. I as i explaind in my first posting, i don't have a BITMAPINFO, can make one manualy? Confused | :confused:

I tried manythings but nothing worked. I'm new to windows programming and MFC.
I'm not at work now, so i don't have the source code here right now.
Eventhough i cann't provide enough info, i hope u can still help me on this one Unsure | :~

Kind regards and thanks again ,

If you know what kind of data is in the pixel array, you should have no problem populating the header.

I've just written and tested this by generating a grayscale gradient and it works.

HBITMAP CreateGrayscaleBitmap(int nWidth, int nHeight, LPBYTE pData)
{
  BITMAPINFO *pbmi = (BITMAPINFO*) new BYTE[sizeof(BITMAPINFO) + (sizeof(RGBQUAD) * 256)];
  ZeroMemory(pbmi, sizeof(BITMAPINFO));
  pbmi->bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
  pbmi->bmiHeader.biWidth = nWidth;
  pbmi->bmiHeader.biHeight = -nHeight;
  pbmi->bmiHeader.biPlanes = 1;
  pbmi->bmiHeader.biBitCount = 8;
  pbmi->bmiHeader.biCompression = BI_RGB;
  pbmi->bmiHeader.biSizeImage = nWidth * nHeight;

  RGBQUAD *pColors = pbmi->bmiColors;
  for(int i = 0; i < 256; i++)
  {
    pColors->rgbBlue = i;
    pColors->rgbGreen = i;
    pColors->rgbRed = i;
    pColors->rgbReserved = 0;
    pColors++;
  }

  CWindowDC dc(NULL);
  HBITMAP hBitmap = CreateDIBitmap(dc, &pbmi->bmiHeader, CBM_INIT, pData, pbmi, DIB_RGB_COLORS);

  delete pbmi;

  return hBitmap;
}

This is for a top-down bitmap. If your image is flipped, remove the negative sign in front of the height.

Hi, i've tried your code in my appicaltion and have another problem now Sigh | :sigh:

. I need a CBitmap object, so i tried the following:

<br />
CDC *pDC = GetDC();<br />
CBitmap* myBitmap;<br />
<br />
myBitmap = CBitmap::FromHandle(hBitmap);<br />
myBitmap->CreateCompatibleBitmap(pDC, m_iWidth, m_iHeight);<br />
myBitmap->LoadBitmap(IDC_STATIC_PICTURE);//picture control in my dialog<br />

I get an Unhandled exception in wingdi.cpp line 1102:

<br />
BOOL CGdiObject::Attach(HGDIOBJ hObject)<br />
{<br />
 ASSERT(m_hObject == NULL); // <= line 1102<br />
   if (hObject == NULL)<br />
     return FALSE;<br />
 CHandleMap* pMap = afxMapHGDIOBJ(TRUE);<br />
 ASSERT(pMap != NULL);<br />
 pMap->SetPermanent(m_hObject = hObject, this);<br />
 return TRUE;<br />
}<br />

This is the call stack:
>mfc71d.dll!CGdiObject::Attach(void * hObject=0x0305061d) Line 1102 + 0x1c C++
mfc71d.dll!CBitmap::CreateCompatibleBitmap(CDC * pDC=0x00816af4, int nWidth=400, int nHeight=400) Line 217 + 0x25 C++

I hope you can help me again here Smile | :)

What are you trying to do here?

The CBitmap::LoadBitmap function is used to load an image into the bitmap, not set an image into a picture control...

I thought that i have to convert the DIB to a DDB Bitmap, so i guess that's wrong Unsure | :~

I just want to display the Bitmap in a picture control, but it's not as easy as i thought

Yes that's stupid, I should have read the MSDN manuals

It is actually.

CStatic *picture = (CStatic*) GetDlgItem(IDC_STATIC_PICTURE);
picture->SetBitmap(hBitmap);

Make sure the static control's type is actually set to Bitmap.
