By buying some graph ActiveX components, or perhaps download some free graph ActiveX components or, dare I say it?, write your own graph ActiveX component.
Google is your friend, if you lack imagination try: "+'Graph'+'ActiveX'+'download'".
There are probably also some free components here at CP in the articles fora.

i think that the message can't translate data with two process. so the first method is failed.

Hi, i'm working in a vision system (artificial vision with a webcam), and i have de adquisition module writed in visual C++ 6.0, and the treatment processes of images writed in matlab. I've already include de matlab source in the visual c++ project, but i need to send the image in memory (a buffer) to the matlab module.

does anyone know what kind of transformation do i must do to my buffer?

or can you explain me how "matlab to VC's traslated source" manipulate the images when the "imread" command were used? D'Oh! | :doh:

any help will be welcome.

thanks

Keep Working!

void CmscprojDlg::OnBnClickedEdit()
{
// TODO: Add your control notification handler code here
UpdateData(true);
char *ptr_filename = new char[1024];
ptr_filename = m_strFilename.GetBuffer(sizeof(ptr_filename));
WinExec("notepad.exe", SW_SHOW);
}

You can USe this Format

CString strToExecute;
strToExecute.Format("notepad.exe %s",<code>m_strFilename</code>);//mind the gap
WinExec(strToExecute, SW_SHOW);

or you can use ShellExecute

::ShellExecute(NULL,<code>"notepad.exe"</code>,<code>m_strFileName</code>,NULL,NULL,SW_SHOWNORMAL);

OnMouseWheel

5-Jan-05 13:15

Maybe a stupid question but: I'm on Win2k with Visual C++ 6.0 and it seems nearly impossible to get any mousewheel code to work.....
I had to specifically #define WM_MOUSEWHEEL 0x020 to avoid "undeclared identifier" messages. Sadly my OnMouseWheel method is not recognized anyway.
I encountered several working MFC examples. Unfortunately I don't use MFC so my question is:
Is it possible to get this working without MFC? Do I need a special include for this?

thanx in advance

Re: OnMouseWheel

From WinUser.h

#if (_WIN32_WINNT >= 0x0400) || (_WIN32_WINDOWS > 0x0400)
#define WM_MOUSEWHEEL                   0x020A
#endif

Notice the #if? Make sure _WIN32_WINNT or _WIN32_WINDOWS is defined properly.

thanks for respons. I'm beginner to Winprog and VC++
I tried including <winuser.h> , but no improvement. Still the same undeclared WM_MOUSEWHEEL identifier.... My WM_LBUTTONDOWN is accepted though, both with and without <winuser.h>. WM_LBUTTONDOWN must be defined elsewhere also I concluded.
Next I outcommented WIN32_LEAN_AND_MEAN in Stdafx.h hoping this would make a difference. nope.
Other includes (a.o.): windows.h en windowsx.h

The button that transforms the url into a link puts a / at the end of the url which shouldn't have been there. Try this.

Thanks. It seems I made a mistake
Moreover I assumed that VC++ would "know" what platform I'm working on: this seems to be not the case.
I #defined _WIN32_WINNT as 0x0500 abd now everything is working fine.. Smile | :)

Reverse Find Index Coblist

Anonymous5-Jan-05 11:08

5-Jan-05 11:08

Is there anyway to reverse find index?

POSITION pos=0;
int index=5;

pos = LinkList.FindIndex(index)
pClass = (CClass*) LinkList.GetNext(pos)
pClass = (CClass*) LinkList.GetNext(pos)

Is there a function to get the index value?

Basically a revsere of
pos = LinkList.FindIndex(index)
Give the pos value and find the index value

You can always write one like this:

int FindObjectIndex(CObList *pList, CObject *pItem)
{
  CObject *pListItem;
  int iIndex = 0;
  POSITION pPos = pList->GetHeadPosition();
  while (pPos)
    {
      pListItem = pList->GetNext(pPos);
      if (pListItem == pItem)
        return iIndex;
      iIndex++;
    }

  return -1;    
}

onwards and upwards...

Doh I was afraid of that, have to go through the whole link list just to find the index value. Guess I will cheat by setting the new index value myself.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
