GetClipboardData(CF_BITMAP) unimplemented

[Kyle Harrigan]

Win32all folks:

I am attempting to use win32all to perform screen captures and save
the bitmap to a file. The call to GetClipboardData fails saying
GetClipboardData(CF_BITMAP) is unimplemented. Any ideas?

My code looks something like this:

win32api.keybd_event(VK_SNAPSHOT, 0x45, KEYEVENTF_EXTENDEDKEY | 0, 0)
win32clipboard.OpenClipboard()
format = win32clipboard.EnumClipboardFormats()
data = win32clipboard.GetClipboardData(format)
win32clipboard.CloseClipboard()
writeFile = open('outfile.bmp','w')
writeFile.write(data)
writeFile.close()

Hi !
And the same for .SetClipboardData(
Please... Please ?

Thanks by advance.

It's just that nobody has written code yet to do anything with the returned
bitmap handle. However, you can still do screen captures without it.
The below code should also work with just about any window handle,
not just the desktop
Roger

import win32gui, win32ui, win32con
hwnd=win32gui.GetDesktopWindow()
l,t,r,b=win32gui.GetWindowRect(hwnd)
h=b-t
w=r-l
hDC = win32gui.GetWindowDC(hwnd)
myDC=win32ui.CreateDCFromHandle(hDC)
newDC=myDC.CreateCompatibleDC()

myBitMap = win32ui.CreateBitmap()
myBitMap.CreateCompatibleBitmap(myDC, w, h)

newDC.SelectObject(myBitMap)
newDC.BitBlt((0,0),(w, h) , myDC, (0,0), win32con.SRCCOPY)
myBitMap.Paint(newDC)
myBitMap.SaveBitmapFile(newDC,'c:\\tmp.bmp')

Hi !

For screen-capture, with PIL, you can do too :

import Image, ImageGrab
ImageGrab.grab().save(filename)

But the question talk of CLIPBOARD and bitmap.
