clipboard

[Jim Clatfelter]

Is it possible when running a PowerBasic DOS program under
Windows to get an entire file into the clipboard? I'd like
to use my PB DOS word processor, then cut an entire file
into the clipboard so I can paste it into email. In other
words, I'd like a Select All capability. All I can do now is
cut one screen.

I suppose you are storing data as text (clipboard data format 1) on the clipboard. You should first test if there is enough memory available to hold your data:

FUNCTION ClipboardFree(BYVAL Bytes AS DWORD) AS DWORD
    DIM HBytes AS WORD
    DIM LBytes AS WORD
    HBytes = Bytes \ 65536  'cut dword in 2 words
    LBytes = Bytes - (HBytes * 65536)
    ! push  ds
    ! mov   ax, &H1709      ;compact clipboard
    ! mov   si, HBytes
    ! mov   cx, LBytes
    ! int   &H2F
    ! mov   HBytes, dx
    ! mov   LBytes, ax
    ! pop   ds
    FUNCTION = HBytes * 65536 + LBytes
END FUNCTION

The function has the amount of needed memory as input, and the available amount as output (the input value is used to re-arrange memory blocks).
If you store text on the clipboard, be sure there are no CHR$(0) characters in it, since that will signal the end of data. I don't see another reason why only 'one page' can be cut to the clipboard.

Jim, I assume you mean that you are using the Windows "copy" function on the visible DOS window? (ie, mouse-click|drag|enter)

If you want to do it programmatically, check out some of the code posted to the ABC site, for example:

Thanks for the reply.
I just want to cut a few screens of text into the clipboard.
There is plenty of memory. But how do I do it?
DOS programs under Win98 only allow me to mark one page.
Is there a PB function that will select and copy a file
or an array to the clipboard? Thanks, Jim

Not from within the IDE, sorry.

Check out Boxer for DOS. I use it to make and compile my programs. It's clipboard is the same as windows. So when you copy stuff in BOXER it is also in the winodows clipboard at the same time.

You can get Boxer at download.com.
