Dear all
I Write one class in Visual C++ which is responsible for logging of stream data.
This Class is used in a dll which is used to contact to hardware.
I want to enable the logging capability in some special times.
But Because this class is used in a dll file, I can not access it via keyboard or mouse. (I dont access the program that uses my dll.)
thus I need an interface to inform my class to enable or disable logging process.
for an example I can create a file in a special place, and my class check the existence of that specific file as a sign of logging permission.
But this solution is not professional.
Thus please send me your idea about this problem.
Thanx in advance
Mahdi

Depends a lot of how you 'use' your dll. Is this class exported by your dll ? If yes, simply treat exactly the same way as if it was part of your application (so, add a function in the class to enable or disable the logging). If it is not exported, you can still export a function in your dll that will allow to enable or disable the logging.

Can you explain this? To able to use your class that logs. There should be some application that uses it?

Can you modify the EXE that uses your DLL?

It's not supposed to be. That's why it's a special ID.
Why can't you just give your static control a different ID?

if you have a variable for static control use CRect rect;m_Static.GetWindowRect(&rect);

for adding Variable to static control you have to Change It's Special ID IDC_STATIC to something else

Hi,
I am working on one CAD application. Application is developed in MFC with document view architeture. In my application there are different views of same geometry object. Views are like FRONT, BACK, TOP etc. Now I want to print all view on same page. In this case TOP view should be in center and all other views should be on different side of TOP view. Is this possible in MFC and if yes then how?
Thanks & Regards,

Hi everybody,
in a CFormView i like to catch the CTRL and Down-Key if i'm at the Grid...
Exists a special key-code for this combination? So that i can catch it over the KeyDown-Event ?
Or only over Accelerators ( But Accelerators working with the MainFrame )
Thanks

Overriding PreTranslateMessage should help.

thanks
yes i did it already for the ENTER Key...
But in the CTRL + DOWN case i must test if two keys were pressed
Must i store the first key in a variable ( activate by on KeyDown, release on KeyUp )
and test so the second key
Or exists a special keycode for double-pressed keys ?

In OnKeyDown (no, thats not the handler for the Down-key pressed  )
you could check for any key-combination like this:
if (Key==VK_DOWN && GetKeyState(VK_CONTROL))
Or, you would check it in PreTranslateMessages:
BOOL CSomeFormView::PreTranslateMessage( MSG* pMsg)
{
if ( WM_KEYDOWN == pMsg->message )
{
switch (pMsg->wParam)
{
case VK_UP:
{
if( GetKeyState(VK_CONTROL))
{
OnUp();
}
break;
}
case VK_DOWN:
{
OnDown();
break;
}
case VK_SPACE:
{
OnStop();
break;
}
}
}
return CFormView::PreTranslateMessage(pMsg);
}
