guys read it carefully

i hav provided odbc connection with an access db1 file

and prepared a ATM project

and used the object m_pSet in all the new classes of dialogs created by me

by passing object of view class as an arguement wen it calls dialog (on button click)

now the problem is

database updation doesnot occur wen we withdraw the money or deposit

it says database updation failed

simply how can v update data frm other class else then view

So is your view derived from CRecordView? Is more than one table involved?

Without a relevant code snippet, it would be impossible to say.

Prior to updating the record, have you called the CanUpdate() method?

Hello,
Currently, I am using LoadImage() to get a handle to an icon that is a resource in my Win32 Application project (using VS2005). Now though, I've added more icons to this icon resource...I now have 3 icons within it, each of 16x16 size, but of different colors (a normal, highlighted and disabled icon).

It looks like LoadImage() is the preferred function to use, but I can't figure out how to extract an icon with a specific index from my icon resource.

Functions like ExtractIcon(), etc. need to be supplied with a path to an .exe, or .ico. I just have it as a resource in my app (ie: IDM_RESET).

Any ideas on the best way to get the icon I want?
Thanks,

Memory DC in OnMouseMove, still blink

The original screen is in MemDC

I copy MemDC to MemDC2 first, then draw cross lines in MemDC2,
at last copy MemDC2 to real dc.

Why is the screen still blink when moving the mouse?

OnMouseMove is a message handler, you need to read the MSDN understand the messaging. The messages come out of the queue and get handled...

Drawing has to be done in OnPaint(). Mad | :mad:

, I didn't realized about it. I thought he was calling the OnPaint when mouse moved. I need to buy me glasses :P

When moving the mouse, WM_PAINT won't be sent, is it sure?

I think it is, so I draw in OnMouseMove, just like scratch in the client when press the left button and dragging in mspaint.

I had read it.
WM_PAINT
WM_MOUSEMOVE
But no answer.

And I read the example Scribble in msdn, it draws in OnMouseMove, but no blinking. I don't know why, maybe the drawing in simple enough.

I also made a test, it shows that in OnMouseMove, OnDraw will not be called.

The problem is I bitblt from memory dc to real dc only once, though slow, it should not blink, then why does it blink?

I am almost sure that for the scribble example, they only store points coordinates in the OnMouseMouse message and they only draw things (meaning calling to MoveTo and LineTo) in the OnPaint handler (and they probably call Invalidate so that the window gets repainted).
At least, that's they way they should do it Smile | :)
