Right. The OP stated "This external obect is not a member function of base or inherited class"
which ~~sounded~~read like it wasn't a class method to me.

Maybe this link will help - Users in Active Directory Domain Services[^]

I chose this link since it also has links to an "old" way to enumerate users Smile | :)

Is it possible to scroll a disabled listbox ? without having to create an owner drawn list.

I have a listbox that gets filled with data but its state is disabled, but I want to be able to scroll the list to see what is in there.

Or maybe I should simply reconsider the UI to allow an enabled list, but "tweaked" to make the list "disabled".

Thanks.

Max.

If you don't accept drag and drop, and make the list box "no selection," why disable it? The user can't do anything to it with those properties set. What are you trying to prevent that you make it disabled?

In my application i have a window that can display different views.

I want to generate bitmaps of some graphs, i have a graph view (CView), but it is not displayed (ie is not attached to the window) at the time.

I think what i want to do is create an offline 'dummy' CView and use OnDraw with a 'memory' dc, so that i can then write it out as a bitmap.

Does anyone have an idea of how to properly create this 'dummy' view so that it would be possible to draw? The CView's base class stuff like the CWnd* handle is not set if i just use the constructor.

I would very much appreciate any guidance.

Simon.

You can hide and show a "view" with ShowWindow() but you'll need to create the window so
the HWND is valid. When the view window is hidden you can't draw on it, so is having an
offscreen view really necessary?

If you really need to do this, you'll still have to repaint the bitmap when the window is shown
so maybe just using one view window and memory bitmap(s) is a simpler solution.

I am not sure what you are doing, but it sounds like you just need to create a bitmap of the information that can be viewed latter. Create a function that you can pass the information to and in it: (1) create a memory dc, (2) create a screen compatible bitmap, (3) select the bitmap to the dc, (4) draw to the dc, (5) restore dc to original state, (6) return new bitmap to caller. Once you have the bitmap can figure out what to do with it at a latter date, including transferring ownership to some future CView window.

Hi, thanks.

Thats the sort of thing i was trying but i'd end up with loads of black lines like a barcode.

I thought it might be because the hwnd of the view hadnt been setup properly or something. My graph data is stored seperately from the view which simply manages the DC and mouse/key strokes.

(The reason im doing it this way is that one view can be made to show different graphs)

I'm trying something that vaguely resembles...

CGraphView dummyview; (derived from CView)<br />
dummyview.SetMyGraph(graph);<br />
dummyview.SetSize(rect);<br />
dummyview.WriteToBitmap("bitmap.bmp")<br />
<br />
CGraphView::WriteToBitmap(CString file)<br />
{<br />
CDC pDC;<br />
pDC.CreateCompatibleDC(CDC::FromHandle(wglGetCurrentDC()));<br />
<br />
CBitmap bitmap;<br />
bitmap.CreateCompatibleBitmap(&pDC, rect.Width());<br />
CBitmap* oldBitmap = pDC.SelectObject(&bitmap);<br />
<br />
OnDraw(&pDC);<br />
<br />
int pixels = rect.Width() * rect.Height();<br />
BYTE* bits = new BYTE[pixels*4];<br />
<br />
glReadBuffer(GL_BACK);<br />
glReadPixels(rect.left, rect.bottom,rect.Width(),rect.Height(),GL_RGBA,GL_UNSIGNED_BYTE,bits);<br />
...<br />
bitmap.SetBitmapBits(pixels*4,bits);<br />
...<br />
then write bitmap to file<br />
}
