Each list view is associated with a list control which we can access by calling GetListCtrl().
How to set this list control to use LVS_OWNERDATA style ?
I've tried to put these in OnCreate or OnInitialUpdate but it didn't work. The list is still not of OWNERDATA style.
CListCtrl &ctlTmp = this->GetListCtrl();
ctlTmp.ModifyStyle(NULL, LVS_REPORT | LVS_OWNERDATA);
how could I do this ?

You can't dynamically set this style - it has to be set when the control is created.
You can pass it with the dwStyle parameter to Create()/CreateEx() or set it in the resource editor
properties if it's a control on a dialog resource.

yeah, if it was a list control in a normal dialog then it would be easy.
But for a list view and its associated list control, I dont' know where and when the list control is created to set its style.

In a CListView derived class, override PreCreateWindow()...
BOOL CMyListView::PreCreateWindow(CREATESTRUCT& cs)
{
if (CListView::PreCreateWindow(cs))
{
cs.style |= LVS_OWNERDATA;
return TRUE;
}
return FALSE;
}

You can override CDialog::OnCancel().
or
ON_WM_SYSCOMMAND()
afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
void CMyDialog::OnSysCommand(UINT nID, LPARAM lParam)
{
if (nID == SC_CLOSE)
{
}
CDialog::OnSysCommand(nID, lParam);
}

Why is it necessary to have a constructor with no arguements if we have the DECLARE_SERIAL macro defined for serialible classes.
|
|
|
|
|
A default constructor is necessary because when un-serializing (loading a serialized object), MFC
needs to be able to create an object of the type serialized (see CArchive::ReadObject()).

How can i access PS/2 ,for ex capturing datas of mouse : will it require upper-level filters to PS/2 mouse device drivers or can i do it via user-mode with IOCTLs or perhaps ReadFile/WriteFile ?
Thank you very much
|
|
|
|
|
i don't think u can use use readfile or writefile. you need to write drivers..
If u can Dream... U can do it

What's wrong with WM_MOUSEMOVE? Then it won't matter what mouse is plugged in. Or are you a PS/2 chipset manufacturer, and damn these ^$&^%£* USB people?
If you're writing games, then you could look at DirectInput too.
These are only valid for MS Windows, but if you not using windows, it would be helpful to let us know that in your post.

I want to create a button that will force an acton to continue as long as the button is "down." For example, I want to increment a displayed field by 1 as long as the button is down. I can increment each time the button is clicked, but can't hold it down and get multiple increments. What's the general approach to this? Thanks.

You can start some timers on on mouse down event ,and in the timers you can do
what ever you want.. and kill the timer on mouseup. it may work
If u can Dream... U can do it

One way would be to respond to the WM_LBUTTONDOWN message for the button control and go into
a modal loop until the button is released:
On WM_LBUTTONDOWN...
::SetCapture(hwnd);
MSG Msg;
memset(&Msg,0,sizeof(MSG));
while (Msg.message != WM_LBUTTONUP &&
(Msg.message != WM_MOUSEMOVE ||
(Msg.wParam & MK_LBUTTON)))
{
if (::PeekMessage(&Msg,0,0,0,PM_REMOVE))
{
::TranslateMessage(&Msg);
::DispatchMessage(&Msg);
}
}
::ReleaseCapture();
A better method would be to do it like the up-down control (spin button) does:
On WM_LBUTTONDOWN
Capture the mouse (::SetCapture())
Create a timer for the desired interval of increments (::SetTimer())
On WM_TIMER
Increment displayed field
Call ::InvalidateRect(hWnd, NULL, bErase) on displayed field control
Call ::UpdateWindow(hWnd) on displayed field control
On WM_LBUTTONUP
Kill the timer (::KillTimer())
Release the mouse (::ReleaseCapture())

Check out CBitmapButton in WTL, that class has this feature (it's called "autofire"), so you could take the code from there.
|

|

Cool!
I have a dumb question....is WTL for XP+ or are lower OSs supported?
Thanks!

It has been a while, but essentially you just need to start a timer that calls a timer message handler of you choice. The timer handler keeps doing the increment until you release the button. When you release the button, then you need to release the timer. This is very similar as to how one selects lines in a text editor (or web page), that is a timer is used to make the window scroll when you mover the mouse cursor near the edge of the window when selecting text.

Hi,
I read a VC++ 6.0 project into Visual Studio and I need to add a reference using the menu Project -> References. However, the menu item "Add new References" does not give me any items to add.
I created a new sample project and the "add new references" dialog lists all the available com objects.
Is there anything I can do to get these items to show up in the converted project? I suppose I could just rebuild the whole project from scratch but if there's an easier way...
Also, if I could ask about the actual COM item I need - I used the Flexgrid in a dialog in the VCC++ 6.0 project. In the sample project I created they did not list this objectin the Add New References dialog. Is the Flexgrid even useable in Visual Studio?
Thanks
