On the Internet to find such a, but is an error, not

The I, is not working, not cut the whole screen, is a custom screen,
QQ has a control can be realized, like QQ screenshots, useful,
But after the QQ screenshots are saved to the clipboard, I'd like to keep the clipboard data into images,
Just don't know how to save, to find on the Internet for a long time can't get a

Experts advise, please, thank you

CodePudding user response:

Which expert to consult

CodePudding user response:

You give examples should be done

Blob blobtemp
If IsClipboardFormatAvailable (2)=1 then
HGlobal=GetClipBoardData (2)
Lp=GlobalLock (hGlobal)
Blobtemp=space (GlobalSize (lp))
The copymemory (ref blbResult BlobTemp, lp)
GlobalUnlock (hGlobal)
End the if
This time is within a BMP image of blobtemp put
You can have a look at the picture control
Picture. SetPicture (blobtemp)
Should be able to show pictures to

What's left is to save the contents of the Blobtemp to file.

CodePudding user response:

Such an error, no one's really tested, counsel, urgent

CodePudding user response:

HGlobal=OpenClipboard (Handle (the Parent))
HGlobal=GetClipBoardData (1)
Lp=GlobalLock (hGlobal)
Li_count=GlobalSize (lp)
MemoryCopy (ls_a, lp, li_count)
GlobalUnlock (hGlobal)
CloseClipboard ()

If the above code, it is no problem, ls_a is clipboard text
But if it is GetClipBoardData (2), to take pictures, GlobalLock returns 0, don't know why

CodePudding user response:

Tried, not really.
This method is a copy of the string.
Copy image with this method is very troublesome.
To use copyimage copy pictures for memory,
And then put the pictures of the memory is saved as a file.

CodePudding user response:

Can post specific code, thank you

The FUNCTION ulong GetClipboardData (ulong wFormat) LIBRARY "user32. DLL
"The FUNCTION ulong IsClipboardFormatAvailable (ulong wFormat) LIBRARY "user32. DLL
"The Function long CloseClipboard () Library "user32
"The FUNCTION ulong OpenClipboard (ulong HWND) LIBRARY "user32. DLL
"The Function ulong CopyImage (ulong handle, long un1, long n1, long n2, long un2) LIBRARY "user32. DLL

Ulong hglobal, ll_hbitmap
If IsClipboardFormatAvailable (2)=1 then
OpenClipboard (handle (the parent))
HGlobal=GetClipBoardData (2)
CloseClipboard();
Ll_hbitmap=copyimage (hglobal, 0,0,0,4)
End the If
Ll_hbitmap is memory picture
But you would have a memory images in the file you trouble

To save HBITMAP handle for local BMP bitmap link:
