Is there any way to copy the title of the active window to the clipboard in Microsoft Windows in Dragon NaturallySpeaking's advanced scripting?
A workaround I use is to define an AutoHotkey script:
^!l::
WinGetActiveTitle, Title
Clipboard = %Title%
return
and call the keyboard shortcut in the voice command:
but I would prefer not to have to jungle it between AutoHotkey and Dragon NaturallySpeaking. Can it be done in "pure" advanced scripting?
Yes, you can copy the title of the active window to the clipboard using Dragon NaturallySpeaking's advanced scripting as follows:
'
' get window title
'
Sub Main
Clipboard ( GetWindowTitle )
End Sub
'
' Use these Windows Functions for Getting an active Window title
'
Declare Function GetForegroundWindow Lib "user32" () As Long
'
Declare Function GetWindowText Lib "user32" _
Alias "GetWindowTextA" ( ByVal hwnd As Long , _
ByVal lpString As String , ByVal cch As Long ) As Long
'
' GetWindowTitle
' (Gets an active Window title)
'
Function GetWindowTitle() As String
Dim x As Integer
Dim TitleText As String * 300
Dim hw As Long
hw = GetForegroundWindow()
x = GetWindowText ( hw , TitleText , Len ( TitleText ) )
GetWindowTitle = Trim ( Left ( TitleText , x ) )
End Function
'
Now, I keep all the functions in a global '#Uses file (with other declarations, functions and global constants, etc.), so I just need the Main Sub part, but you can put all of the referenced functions and declarations in the one script where you need it, too.

I need code for removing all unicode characters in a vb6 string.
If this is UTF-16 text (as normal VB6 String values all are) and you can ignore the issue of surrogate pairs, then this is fairly quick and reasonably concise:
Private Sub DeleteNonAscii(ByRef Text As String)
Dim I As Long
Dim J As Long
Dim Char As String
I = 1
For J = 1 To Len(Text)
Char = Mid$(Text, J, 1)
If (AscW(Char) And &HFFFF&) <= &H7F& Then
Mid$(Text, I, 1) = Char
I = I + 1
End If
Next
Text = Left$(Text, I - 1)
End Sub
This has the workaround for the unfortunate choice VB6 had to make in returning a signed 16-bit integer from the AscW() function. It should have been a Long for symmatry with ChrW$() but it is what it is.
It should beat the pants off any regular expression library in clarity, maintainability, and performance. If better performance is required for truly massive amounts of text then SAFEARRAY or CopyMemory stunts could be used.
Public Shared Function StripUnicodeCharactersFromString(ByVal inputValue As String) As String
Return Regex.Replace(inputValue, "[^\u0000-\u007F]", String.Empty)
End Function
Vb6 - not sure will
sRTF = "\u" & CStr(AscW(char))
work? - You could do this for all char values above 127
StrConv is the command for converting strings.
StrConv Function
Returns a Variant (String) converted as specified.
Syntax
StrConv(string, conversion, LCID)
The StrConv function syntax has these named arguments:
Part Description
string Required. String expression to be converted.
conversion Required. Integer. The sum of values specifying the type of conversion to perform. `128` is Unicode to local code page (or whatever the optional LCID is)
LCID Optional. The LocaleID, if different than the system LocaleID. (The system LocaleID is the default.)
I have a special case when the user is first typing through IME by Press Alphabetic KeyCode on my Grid UserControl, How do I pick up the Unicode on IME Window? If the user is typing in English, it is OK. But if the user is typing Chinese or Japanese on IME, the Unicode turns into question marks.
Select Case uMsg
Case WM_IME_SETCONTEXT
If Not wParam = 0 Then
Dim flag As Boolean
flag = ImmAssociateContextEx(lng_hWnd, 0, 16)
If flag Then
Dim IntPtr As Long
IntPtr = ImmGetContext(lng_hWnd)
flag = ImmSetOpenStatus(IntPtr, True)
End If
End If
Case WM_IME_STARTCOMPOSITION
Dim hIMC As Long
hIMC = ImmGetContext(lng_hWnd)
Dim cf As COMPOSITIONFORM
cf.dwStyle = 2
cf.ptCurrentPos.X = UserControl1.ScaleLeft + 3
cf.ptCurrentPos.Y = UserControl1.ScaleTop + UserControl1.Height - 16
ImmSetCompositionWindow hIMC, cf
Case WM_IME_CHAR
'Send IME Char to UserControl1.KeyPress
UserControl1_KeyPress(wParam And &HFFFF&)
Exit Sub
End Select
After I use different Subclasser from Krool, now I can get Right Unicode. Not sure why Paul Caton and LaVolpe cSelfSubHookCallBack doesn't work.
The Subclasser may internally turn Unicode to ANSI or failed to prevent Windows from UNICODE to ANSI conversion.
In f90 I need to encode a 30 character string as real/double and recover it in a different place from this real/double number. How to do that?
Thanks,
Mark
I wouldn't use doubles, I'd use integers. Specifically an array of integers. And the intrinsic functions ichar and achar that convert a character to its ASCII equivalent and back (respectively).
You could whip this up easily:
program string_to_int
implicit none
integer :: mystring_int(30), i
character(len=30) :: mystring
mystring = "Fortran is the best language!!"
do i=1,30
mystring_int(i) = ichar(mystring(i:i))
enddo
print *,mystring_int
call read_back_int(mystring_int)
contains
subroutine read_back_int(cvar)
integer, intent(in) :: cvar(:)
character(len=size(cvar)) :: substring
integer :: i
do i=1,size(cvar)
substring(i:i) = achar(cvar(i))
enddo
print *,substring
end subroutine read_back_int
end program string_to_int
Using the (intrinsic) function sizeof, it shows me that the character string is 30 bytes while integer array is 120 bytes. If you really want to use double, then replacing integer with real(kind=c_double) (which requires the iso_c_binding module) would do the trick too.
I have some customers who want to use our speech therapy software in Hebrew.
The programs are in VB6. The best option I'm aware of are:
use the Forms 2.0 controls from MS Office, but you can't distribute them.
http://www.hexagora.com/en_dw_unictrl.asp $899
http://www.iconico.com/UniToolbox/ $499
Any other options?
I found this tutorial very useful. Yes it is partially an ad for another Unicode Control Suite, but it has a lot of information about how to do it yourself and what issues are involved.
EDIT
I knew I had way more on this stored in my bookmarks.
First of all there is an article from Chilkat (another component vendor) about how to use the Font's charset (assuming it is a unicode font) to set different font types (you have to manually change the .frm since charset isn't exposed in the gui). Then all you have to do is convert from AnsiToUTF8 and back to support different languages (that is what Chilkat's control does).
Second, there are the Vesa Piittinen's free (Creative Commons, source included) VB6 controls for download here. They include Textbox, Label, Menu, List, Dialog, CommandButton, Caption (form's caption)). I haven't played with them much, but basically he is doing all the onPaint and the nice thing is that is all done in VB and you can look at the source.
Presumably your users don't have Hebrew selected as the system default code page, otherwise you could just use the native VB6 controls (bearing in mind that Hebrew is right-to-left, obviously!).
Don't use Forms 2 - it will crash your VB6 program. Microsoft Knowledge Base article: "FM20.DLL is known to have many problems when used with Visual Basic and other developer products. Its use is neither recommended nor supported in any Visual Studio product."
I've no personal experience of the others, but your #3 option UniToolbox has been around for years and Google throws up some positive chatter about it on the newsgroups (EDIT - for instance VB6 internationalisation guru Michael Kaplan recommended it in a post in 2004 and a blog post in 2005).
One whacky option is to use API calls with the native VB6 controls - some pointers in Michael Kaplan's excellent book on Internationalization with VB6 and some sample code on his website too. But it would be lots of work. Do buy the book anyway as it's a gold mine of information on international issues in VB6. For instance the sample chapter explains your problems with Hebrew. Look for it secondhand as it's out of print.

According to KB224305 ("INFO: Usage and Redistribution of FM20.DLL"), you can install the free "Microsoft ActiveX Control Pad", which in turn installs the Forms 2.0 Library.

Charset table from this link
DBCS - Double-Byte Character Set
DBCS is actually not the correct terminology for what Windows uses. It is actually MBCS where a character can be 1 or 2 bytes. To illustrate this consider the following code which will take a Unicode string of English and Chinese characters, convert to a byte array of MBCS Chinese, dump the byte array to the immediate window, and finally convert it back to a Unicode string to display in a Unicode aware textbox. The byte array when converted using Chinese(PRC) LCID = 2052 contains single bytes for the english characters and double bytes for the Unicode characters. This proves that it is MBCS and not DBCS:
Here are some comments about displaying Unicode characters in Microsoft Visual Basic forms using resource (.RES) files:
When I pasted Russian or Japanese characters to Microsoft Visual Basic 6 Resource Editor when creating a resource (.RES) file, the characters would appear as question marks (?) both in MSVB6 Resource Editor and in MSVB6 forms displayed on a computer with Russian or Japanese locale, respectively, using the resource DLL that I built from the RES file through MSVB6.
However, if I added the characters to the resource file by pasting them into Resource Hacker http://www.angusj.com/resourcehacker, the characters still would display as question marks in MSVB6 Resource Editor, but would display correctly on a computer with appropriate locale after I built the resource DLLs through MSVB6.
One can make resource DLLs for each of several languages and use Microsoft's GetUserDefaultLCID or GetUserDefaultLocaleName to decide which to load.
