3d Plot in Visual C++ 6.0

3-Feb-05 23:02

A simple method is to override the WM_WINDOWPOSCHANGING message (OnWindowPosChanging).

<code>
<font color="green">// Modify flags to prevent window movement</font>
void CMyDlg::OnWindowPosChanging(WINDOWPOS* lpwndpos)
{
 lpwndpos->flags |= (SWP_NOMOVE | SWP_NOSENDCHANGING); 
 CDialog::OnWindowPosChanging(lpwndpos);
}
</code>

Hi,

I am looking for a Visual C++ 6.0 compatible plotting library with 3D plot. Some features like saving the plot would be nice as well. (library can be commercial).

Thanks,

and

Hi all:
How can I specify the height and width of the window appeared after I click the Date Time Picker Control?

Thanks!

How about

CWnd::MoveWindow(...)

After tinkering with the control, I found that the little drop down window is a CMonthCalCtrl that you can access using the GetMonthCalCtrl() member function of the CDateTimeCtrl class.
This window is created dynamically when you click on the drop down button, so you will need to access this class on the drop down event (DTN_DROPDOWN).

The problem is that resizing this window does not resize the individual control, only allow more calendar months to be displayed; a bit like how Outlook displys its months at the side of the frame.

<code>
void CTestDlg::OnDtnDropdownDatetimepicker1(NMHDR *pNMHDR, LRESULT *pResult)
{
 CMonthCalCtrl* pCtrl = this->m_DateTimeCtrl.GetMonthCalCtrl();
 if(pCtrl != NULL)
 {
   CRect rect;
   pCtrl->GetClientRect(&rect);
   rect.InflateRect(70, 90);
   pCtrl->MoveWindow(&rect);
 }
 *pResult = 0;
}
</code>

Thanks for you attention
But the result I get after running your code is like this:
The control size itself is still the same, But around it there's a rectangular and there has some space between them!
Is it impossible to changed the drop down window?

That was my original point. The actual drawing of the month grid won't change. The container window will size, but the container dates will not size with it.
Try sizing the window to 2x (2 times), the window width and you will see what I mean).
If you need a scalar zoom of the window, then I think you are out of luck, unless someone else knows different (let me know).

Change to this
rect.InflateRect(140, 180);?

Are you talking about at design time or at run time?

Have you tried SetForegroundWindow()

Antony,
thank you for your answer.
The problem is that SetForegroundWindow(), ShowWindowAsync() and other window managing funcion I found need an HWND window handler.
Unfortunately MyProcess[0]->MainWindowHandle is a IntPtr (an __int32 at the end).
I wasn't able in any way to get an HWND handler to the window from the IntPtr returned. The compiler always stops me Confused | :confused:

Bye,
Maurizio

Where did you get the class Process from? What is the code in the GetProcessByName function?

It may be that you can just cast the returned __int32 to a HWND.

I'm not quite clear on what you want to achieve.
In any case, you cannot use the CString constructor like that in the second case.

I feel its a valid call. But gives an error coz CString::Format() returns void.

You're absolutely correct. My bad D'Oh! | :doh:

.

The following does indeed compile, though how it could be used in a useful way is still a puzzle. (since it cannot be assigned to anything) Hmmm | :|

void MyFunction()
{
 CString("Hey").Format("There!");
}

That compiles *and* runs successfully.

The problem is that CString::Format's return type is void. So that's the return type of this statement, and there doesn't seem to be any way to convert that to the LPCTSTR that AfxMessageBox expects.

It's going to take some serious obfuscation to make this work. My question is...what's wrong with a local CString variable? Like it or not, the statement itself is creating a local CString that goes out of scope after the statement executes.
