StretchBlt returns Nonzero if the bitmap is drawn; otherwise 0.

Not all devices support the StretchBlt function. To determine whether a device supports StretchBlt, call the GetDeviceCaps member function with the RASTERCAPS index and check the return value for the RC_STRETCHBLT flag.

Somethings seem HARD to do, until we know how to do them.

You can draw your bitmap directly on the printer dc handle

Hi All,

I am stuck with ideas on how to gain access to the controls of a webcam.
What I want to achieve it to write a C++ program to capture images from a webcam.
Does anyone know of a nice and simple method I can do this.
I have been looking at TWAIN and WIA, but seems so complex to get started.
Cheers,
Chee

Edit Control - Cursor Position

si_6919-Jul-06 3:12

Hi
Can anyone tell me how i can set the position of the cursor in an Edit Control

i want to place a space after the user enters a full stop, im using the below, but this just
puts the cursor back to the start, rather than the end

CString csText, csText2;
m_c_sms.GetWindowText( csText );
csText2 = csText.Right(1);
if (csText2 ==".")
{
csText = csText+" ";
m_c_sms.SetWindowTextA(csText);

}

also :

don't use SetWindowTextA() but SetWindowText().

BTW, AFAIK, you can use CEdit::SetSel(end, end);

I believe these are in the wrong order.

Why not something simple like:

CDatabase db;
db.ExecuteSQL("DELETE FROM table);

I guess it is to do with Update.
See MSDN help. It say's

Unlike AddNew and Edit, a call to Delete is not followed by a call to Update.
