RE: & Character problem - Dale Yarker - 30.09.2025
unable to duplicate problem with:
Code:
#compile exe
#dim all
%UNICODE = 1
function pbmain () as long
local W, RtoL as wstring
local R as string
local hDlg as dword
W = chr$$(&h1D08)
RtoL = chr$$(&h21D0) 'F4)
dialog default font "Consolas", 10, 0, 1
dialog new 0, W, , , 150, 50, %ws_overlappedwindow, %ws_ex_left or _
%ws_ex_ltrreading to hDlg
control add textbox, hDlg, 1000, "", 5, 5, 40, 12
dialog show modal hDlg
end function and typing into textbox as stated using PBWin 10 on Windows 10
Cheers,

doing xprint better to print to file than waste paper
RE: & Character problem - Dale Yarker - 01.10.2025
"screen show AB <-- SHOULD BE B UNDERLINE"
I get AB with B underlined in label here after clicking DONE. No idea why you don't.
For A&&B I get A&B as said.
The pdf after PRINT shows content of textbox for A&B and A&&B. "&&" tries to hotkey the second "&", it can't so just shows one.
Post 1 did not mention display in label, so I was not surprised when the textbox when B was not underlined.
All the help I have, bye from this.
Cheers,

Known behaviour of recent versions of Windows.
By default, you need to hit Alt key to show keyboard shortcuts in menus and labels (and button text).
"&&" shows the character "&" in such controls and it is NOT a shortcut.
To demonstrate more clearly, try "&DONE" as the button label
Demonstration of what is actually stored:
Code:
#COMPILE EXE
#DIM ALL
%UNICODE = 1
GLOBAL hDlg AS DWORD, A AS STRING
CALLBACK FUNCTION DisplayIt
LOCAL s AS STRING
CONTROL GET TEXT CB.HNDL, 1002 TO s
? s & $LF & A
END FUNCTION
CALLBACK FUNCTION TEXTT()
CONTROL GET TEXT hDlg, 1000 TO A
CONTROL SET TEXT hDlg, 1002, A
END FUNCTION
FUNCTION PBMAIN () AS LONG
LOCAL W, RtoL AS WSTRING
LOCAL R AS STRING
W = CHR$$(&h1D08)
RtoL = CHR$$(&h21D0) 'F4)
DIALOG DEFAULT FONT "Consolas", 10, 0, 1
DIALOG NEW 0, W, , , 150, 50, %WS_OVERLAPPEDWINDOW, %WS_EX_LEFT OR _
%WS_EX_LTRREADING TO hDlg
CONTROL ADD TEXTBOX, hDlg, 1000, "", 5, 5, 40, 12
CONTROL ADD BUTTON ,hDlg,1001, "&DONE", 50,5,40,12, CALL TEXTT
CONTROL ADD LABEL ,hDlg,1002, "XX", 50,25,40,12, '
CONTROL ADD BUTTON ,hDlg,1003, "Display", 100, 5,40,12, CALL Displayit
DIALOG SHOW MODAL hDlg
END FUNCTION
You can control this behaviour with:
Control Panel > Ease of Access Center > Make the keyboard easier to use > Enable "Underline keyboard shortcuts and access keys".
RE: & Character problem - Borje Hagsten - 01.10.2025
To always show & in static (label) control, add %SS_NOPREFIX style to it.
MS explains: "Prevents interpretation of any ampersand (&) characters in the control's text as accelerator prefix characters. These are displayed with the ampersand removed and the next character in the string underlined. This static control style may be included with any of the defined static controls.
An application can combine SS_NOPREFIX with other styles by using the bitwise OR (|) operator. This can be useful when filenames or other strings that may contain an ampersand (&) must be displayed in a static control in a dialog box."
Code:
'======================================================================
#COMPILE EXE
#DIM ALL
'--------------------------------------------------------------------
%UNICODE = 1
#INCLUDE "WIN32API.INC"
'--------------------------------------------------------------------
%IDC_LABEL1 = 501

I think he did not want to see the &, he wanted the hot-key. The & was not showing, correct, but not getting the underline indicating the hot-key took affect.

N.B. Applies to Labels but not to Buttons. (for a button, you have to use "&&")

%SS_NOPREFIX Fixed the problem
thanks Borje and everyone for your help and comments
RE: & Character problem - Borje Hagsten - 01.10.2025
For buttons, use ownerdrawn and DrawText with %DT_NOPREFIX format.
