hi all,
I am developing a MFC Project.Now I want to display a light when clicking "Display Light" Button. I have a LED Bulb.
Procedure is like this:-
When I click "display Light" button,the LED(or a bulb) should be ON..otherwise LED should be OFF.

How do I do such a Task?. Is there a DLL or component to accomplish that task?
if any one know about that ,please help me? Frown | :(

Thanks in advance

is that a real buld/light/LED ? if so, there should be an API with some kind of external domotic controller ?

if not, what exactly you want to do ?

Open the image in Microsoft Paint and then use the saveAs option. I think it is under File.

I send data to device.I send 1.
I use this code.
int i=13; //enter key
CString mm=i;
CString mmm=m_text+mm;//m_text=1

if(!(port.WriteString(mmm)))
{
MessageBox("Cannot Write to Port","Error",MB_OK); port. ClosePort();
}
else
{
MessageBox("Send by "+mmm,"Success",MB_ICONINFORMATION); }

Function is work. But PLC is not translate.
I want to know how to get send data.

Spin Control with Real Numbers

19-Oct-04 21:56

Using a Spin Control with real numbers, but have a problem when the Up or Down spin is held down for a while.
The data increments/decrements but after a period (around 30 ~ 100) the sign of the data changes.

I am using my own routine to handle the increments/decrements via OnDeltaposSpinNewdata. The Autobuddy is set to false and the Set Buddy Integer is set to true (tried false but still the same).

void CEditDlg::OnDeltaposSpinNewdata(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
   LPNMUPDOWN pNMUpDown = reinterpret_cast<LPNMUPDOWN>(pNMHDR);<br />
   // TODO: Add your control notification handler code here<br />
	<br />
   int incrementValue;<br />
<br />
   m_fSpinIncrement = m_fScalingFactor;<br />
   if(pNMUpDown->iDelta == -1)	// Increment the value<br />
   {<br />
      IncrementData(m_fSpinIncrement);<br />
   }<br />
   else	// Decrement the value<br />
   {<br />
      DecrementData(m_fSpinIncrement);<br />
   }<br />
   *pResult = 0;<br />
}

C++ Runtime - different Instance in DLL?

peterchen19-Oct-04 21:53

19-Oct-04 21:53

I am not sure about this: When I have a DLL and an EXE compiled with VC, and the EXE loads the DLL, does each have it's own instance of the C runtime (i.e. the global variables like stdin, stdout, the heap, etc.)? Does this depend on compile settings?

TIA

Yes, that is why you should avoid using free() and the delete operator on pointers received from a dll.

Depends on compile settings[^]. If you choose to dynamically link CRT in all your modules (exe and dlls), it will be shared between them and it is safe to pass objects between modules.

Hi,

Yes, you need to load that Accelerator table.
HACCEL gAccel; //Declare in header file

//Add this code to the OnInItDialog of your dialog class
gAccel = LoadAccelerators(AfxGetApp()->m_hInstance,MAKEINTRESOURCE(IDR_MYACCEL));

//Add this code to PreTranslateMessage
if(TranslateAccelerator(AfxGetMainWnd()->m_hWnd,gAccel,pMsg))
return FALSE;

This should work....
Thanx and Bye
