>Hi all,

>I wonder if someone can tell me how to determine whether the clipboard contains an image. As far as I can see, this is not possible using VFP functions, but I guess there is a way via a GDI function or WinAPI.

You can use something like this:
*
* Predefined Clipboard Formats - winuser.h
*
#define CF_TEXT             1
#define CF_BITMAP           2
#define CF_METAFILEPICT     3
#define CF_SYLK             4
#define CF_DIF              5
#define CF_TIFF             6
#define CF_OEMTEXT          7
#define CF_DIB              8
#define CF_PALETTE          9
#define CF_PENDATA          10
#define CF_RIFF             11
#define CF_WAVE             12
#define CF_UNICODETEXT      13
#define CF_ENHMETAFILE      14
#define CF_HDROP            15
#define CF_LOCALE           16
#define CF_MAX              17
#define CF_OWNERDISPLAY     0x0080
#define CF_DSPTEXT          0x0081
#define CF_DSPBITMAP        0x0082
#define CF_DSPMETAFILEPICT  0x0083
#define CF_DSPENHMETAFILE   0x008E
Declare short IsClipboardFormatAvailable in win32api integer cbformat
? ( IsClipboardFormatAvailable(CF_BITMAP) # 0 )
