BlendFunction.BlendOp = AC_SRC_OVER
.blendflag = 0
.SCA = 255
.AlphaFormat = AC_SRC_ALPHA
My bmp is per-pixel alpha channel bitmap.
I googled something articles and turuned out I didn't do the premultiple, but I am still comfused with the following formula:
Dst.Red = Src.Red + (1 - Src.Alpha) * Dst.Red
where the Src.alpha's value making sense should be 0.0 - 1.0, but it is 0 - 255. I wonder OS translate the alpha value in background for us?

MFC doesn't have WM_SETFONT message handle, such as OnSetFont(...), how to add it as standard MFC handle?
I mean, not use WindowProc(...) etc.

Are you wanting to intercept the WM_SETFONT message? Do you have a custom control that has a WndProc() function?

I think you can use ON_MESSAGE
0N_MESSAGE(WM_SETFONT, OnSetFont)...
where OnSetFont is declared as afx_msg LRESULT OnSetFont(WPARAM, LPARAM). and WPARAM contains HFONT.

While you probably meant ON_MESSAGE(), isn't that for user-defined messages and less-common Windows messages?

WM_SETFONT is a message sent TO a window (control). That's why it doesn't have a handler macro.

Hi:
first i invoke CreateRoundRectRgn(rc.left, rc.top, rc.right, rc.bottom, 5, 5) create a HRGN, then Invoke SetWindowRgn.
SetWindowRgn is successful But RoundRect(hdc, rc.left, rc.top, rc.right, rc.bottom, 5, 5) can not Draw round border,
I am surprised Because RoundRect Draw the top and left border, but not draw right and bottom border. Please Help me thanks.
the code as follow:
HRGN hRgn = CreateRoundRectRgn(rc.left, rc.top, rc.right, rc.bottom, 5, 5);
::SetWindowRgn(hwnd, hRgn, TRUE);
RoundRect(dcMem, rc.left, rc.top, rc.right, rc.bottom, 5, 5);

how you are calculating rc?

|
|
|
|

calculate like this:
RECT rc;
GetWindowRect(hwnd,&rc);
OffsetRect(&rc,-rc.left,-rc.top);

thanks the problem is solved

This is information based on a previous issue (also in Delphi forum) by OP.

Is this related to C/C++ in any way?
|
|
|
|
|
See above.

But this still does not fix your problem as far as I can see. It is still not possible to get the information out of the .lnk file. Or have I missed some extra information?

That is completely incomprehensible, so I'll have to go for a very wild guess.
If you make a shortcut file containing a URL (e.g. by dragging the content of the address bar from a browser to the desktop), then you get what is basically a text file; the second line contains
URL=the URL your browser was showing at the time
so some simple read-string-from-file operations can give you the URL string.

Exactly right Luc. However, OP had a .lnk file which contained a URL as the link rather than a file path, but was still not in URL shortcut format, and could not be read via the IShellLink interface. The issue is in the Delphi forum, and I'm not sure why he posted the above message as it still does not contain a resolution as far as I can tell.

OK, I now have read some of that Delphi thread, seems like a bit of a scatterbrain.
BTW, it seems an LNK file isn't text, are you aware of this?

Yes, and that is the problem. A URL link (correctly constructed) is a text file and can be read easily. A .lnk file uses some internal Microsoft (not published) structure, and you can only access its content through the IShellLink interface. The file that the OP has is a 'normal' .lnk file but its path contains a URL, which is illegal. So, you cannot read it as a text file and the IShellLink functions will not give you access to its contents either. Catch 22.
