CWindow RC06

[José Roca]

But when I use

Code Select Expand


#define unicode
#INCLUDE ONCE "windows.bi"
#Include Once "Afx/widestring.bi"

DIM s AS STRING = CHR(209, 229, 236, 229, 237)
DIM wsz AS WSTRING * 260
MultiByteToWidechar(1251, MB_PRECOMPOSED, STRPTR(s), -1, @wsz, SIZEOF(wsz))
DIM bs AS WideString = wsz
MessageBoxW 0, bs, "", MB_OK


the opeator that is being called is not the one with BYREF AS WSTRING, but

Code Select Expand


Operator WideString.Cast() As BSTR
if m_bstr=NULL  Then
   Return SysAllocString(WStr(*m_str))
Else
   Return m_bstr
End If
End Operator


[José Roca]

If I add this operator to my class, it works

Code Select Expand


' ========================================================================================
' Returns a pointer to the BSTR
' ========================================================================================
OPERATOR CBStr.CAST () BYREF AS WSTRING
'   OPERATOR =  PEEK(WSTRING, m_bstr)
   OPERATOR =  *CAST(WSTRING PTR, m_bstr)
END OPERATOR
' ========================================================================================


[José Roca]

I'm very interested in that BYREF thing, because

Code Select Expand


FUNCTION Foo () AS BSTR
   DIM bstrHandle AS BSTR
   bstrHandle = SysAllocString("Test string")
   FUNCTION = bstrHandle
END FUNCTION

DIM bs AS CBSTR
bs = Foo
' we can use
print bs
' instead of
'print *bs.Handle
'-or-
'print **bs
' that also work


[José Roca]

This is a version of CBStr.inc with the BYREF AS WSTRING cast operator added.
See attachment.

[José Roca]

Interesting test:

Code Select Expand


#INCLUDE ONCE "windows.bi"
#INCLUDE ONCE "Afx/AfxWin.inc"
#INCLUDE ONCE "Afx/CBStr.inc"

using Afx.CBStrClass

DIM bs1 AS CBStr = "First"
DIM bs2 AS CBStr = "Second"
print bs1, bs2
print bs1 & bs2
print **bs1 & " --- " & **bs2   ' this works
'print bs1 & " --- " & bs2   ' this does not work; type mismatch error
print bs1 & " --- " & **bs2   ' this works
'print **bs1 & " --- " & bs2   ' this does not work; type mismatch error
dim s as string
s = bs1 & bs2
print s

print "press esc"
sleep


[José Roca]

I have modified the functions that load icons from file or resource to allow to pass a dimming percentage and/or gray escale conversion. This way, with only a set of icons we can buid both the normal imagelist and the disabled one, e.g.

Code Select Expand


   ' // Create an image list for the toolbar
   DIM hImageListNormal AS HIMAGELIST
   DIM cx AS LONG = 16 * pWindow->DPI \ 96
   hImageListNormal = ImageList_Create(cx, cx, ILC_COLOR32 OR ILC_MASK, 4, 0)
   IF hImageListNormal THEN
      ImageList_ReplaceIcon(hImageListNormal, -1, AfxGdipImageFromResEx(hInst, "IDI_NEW_32"))
      ImageList_ReplaceIcon(hImageListNormal, -1, AfxGdipImageFromResEx(hInst, "IDI_OPEN_32"))
      ImageList_ReplaceIcon(hImageListNormal, -1, AfxGdipImageFromResEx(hInst, "IDI_SAVE_32"))
   END IF
   SendMessageW hToolBar, TB_SETIMAGELIST, 0, CAST(LPARAM, hImageListNormal)

   ' // Create the disabled image list for the toolbar
   DIM hImageListDisabled AS HIMAGELIST
   hImageListDisabled = ImageList_Create(cx, cx, ILC_COLOR32 OR ILC_MASK, 4, 0)
   IF hImageListDisabled THEN
      ImageList_ReplaceIcon(hImageListNormal, -1, AfxGdipImageFromResEx(hInst, "IDI_NEW_32", 60, TRUE))
      ImageList_ReplaceIcon(hImageListNormal, -1, AfxGdipImageFromResEx(hInst, "IDI_OPEN_32", 60, TRUE))
      ImageList_ReplaceIcon(hImageListNormal, -1, AfxGdipImageFromResEx(hInst, "IDI_SAVE_32", 60, TRUE))
   END IF
   SendMessageW hToolBar, TB_SETDISABLEDIMAGELIST, 0, CAST(LPARAM, hImageListDisabled)


With only a set of icons we can display them with the appropriate size for the DPI chosen by the user, both in toolbars and in menus.

It's time to throw to the recycle bin these old bitmaps with a pink background and without alpha channel that we used in the past.

[aloberr]

your example CWindow with a rebar control don't work anymore

[José Roca]

This is because I have removed the auxiliary functions from CWindow.inc. What I'm posting is testing code.

Add the functions to the example and it will compile:

Code Select Expand

   IF fsState = 0 THEN fsState = TBSTATE_ENABLED
   DIM idxString AS INT_PTR
   IF pwszText <> NULL THEN idxString = IIF(LEN(*pwszText) = 0, -1, CAST(INT_PTR, pwszText))

#endif
   FUNCTION = SendMessageW(hToolBar, TB_ADDBUTTONSW, 1, CAST(LPARAM, @tbb))
END FUNCTION
' ========================================================================================


[José Roca]

BTW do you know why this compiles

Code Select Expand


DIM tbb AS TBBUTTON = (idxBitmap, idCommand, fsState, fsStyle, {0, 0, 0, 0, 0, 0}, dwData, idxString)


but this one don't

Code Select Expand


DIM tbb AS TBBUTTON
tbb = (idxBitmap, idCommand, fsState, fsStyle, {0, 0, 0, 0, 0, 0}, dwData, idxString)

Hi Paul,

Good news. I have succesfully translated my graphic control to FreeBasic.

[Paul Squires]

That's awesome Jose!

I had also converted my version of the image control to FreeBasic: http://www.planetsquires.com/protect/forum/index.php?topic=3701.0
