I'm not sure I follow you 100%.  Maybe what Lazarus IDE needs is the
"detachable menus" - a feature supported by GTK for decades, but seldom
used. If you don't know, "detachable menus" are popup menus say from the
main menu, but the fist entry is a dashed line. If you click the dashed
line entry, that popup menu detaches and becomes a independent window
which you can place anywhere on the screen, and it says open. Clicking
the menu items in that detached windows DOESN'T close the window (unlike
what happens in popup menus). So this gives you a kind of "command
toolbar" all over the place.

In general it is better to explicitly handle your transactions.
However, if you don't do that, then SQLDB will do it for you.



Note that in our stored procedures in MSSQLServer there are
transactions built-in where they are needed to safeguard consistency
across data in different tables for insance.


This is a given. You cannot disable transactions on a RDBMS server. 
(MySQL is not a RDBMS server in this sense)


They always are part of the game, but some engines 'hide' them by doing
transaction management implicitly.


The SQLDb transactions are still a bit unclear to me.
As yet I have only run stored procedures that return datasets
(basically select procedures) and these work OK but I don't know if
the transaction object really is involved here...

It seems like a TSQLTransaction activity is only needed if data are to
be changed in the database and not if they are only read from the
database. Is this correct?


Even reading is done in the context of a transaction.
But, quite often, it happens in an 'implicit' transaction.

Thank you. I'll get an update today and retest.

As for IDE commands vs Other commands. I don't know how they are
organised... the hierarchy seems different to the IDE main menu. The eg:
Debug Windows menu items are in the IDE main menu hierachy, but not in
the IDE Command hierarchy. Weird.

I use shortcuts extensively, and I also remap shortcuts extensively to
suite my needs The standard ones often don't work well for the
Dvorak keyboard layout. So for the odd ball cases where I can't think of
a logical keyboard shortcut, I assigning those actions to the editor
toolbar, where I can find them very fast.

acceptable with proper PME/generics/other stuff.

I found this tutorial on how to use XMing with RPi:
http://www.raspians.com/Knowledgebase/how-to-remote-desktop-with-xming-and-putty/

It is a bit roundabout, occupying the console connection via PuTTY,
but it did work to bring up some form of X window on my screen.
The displayed RPi desktop


Stop right there. What you're describing there is doing a remote X11 
login to the display manager [qv] running on the RPi, which starts off a 
window manager [qv]. The window manager supplied as default by Raspbian 
assumes that it's running on an RPi, and won't like being accessed over 
the LAN from XMing which is fairly old code and lacks stuff added 
comparatively recently to X11.


WITH THE IMPORTANT CAVEAT THAT I'VE NOT DONE THIS MYSELF ON WINDOWS:

What you should be doing is making sure that your SSH client (Putty or 
whatever) is set up to tunnel X11 sessions, and that the SSH server on 
the RPi is set up to make them available (it is on most distreaux).


Then SSH into the RPi to get a shell, and run your Lazarus binary. At 
that point the X11 messages originated by Lazarus are tunneled over the 
SSH session, and the Lazarus windows/forms /should/ (if Putty+XMing 
really does behave like SSH etc. does on unix) appear as separate 
windows on your client system. What's more, /if/ things are working 
properly, then cut-and-paste should work.


AGAIN, THAT'S WHAT HAPPENS ON UNIX. MY UNDERSTANDING IS THAT THE 
COMBINATION OF PUTTY AND XMING SHOULD GIVE YOU SOMETHING COMPARABLE ON 
WINDOWS, BUT I'VE NOT DONE IT MYSELF.


With apologies to the list managers if this is considered off-topic.

I'm not sure that Putty includes an X server, but it will interwork with 
 (not sure if this name is 100% accurate) XMingw32. That's one reason 
why I suggested starting off with an X11 (Linux etc.) desktop system as 
a client.


As an additional point but not directly relevant to SSH tunneling, I 
don't know whether the display manager (Bo, if you don't grok that see 
Wp) supplied as default with Raspbian allows remote logins. I've started 
using pukka Debian on an RPi2 with KDE hence KDM etc., which turns out 
to be better than Raspbian on several fronts.

I found this tutorial on how to use XMing with RPi:
http://www.raspians.com/Knowledgebase/how-to-remote-desktop-with-xming-and-putty/

It is a bit roundabout, occupying the console connection via PuTTY,
but it did work to bring up some form of X window on my screen.
The displayed RPi desktop is very strange, though. Not at all the
Jessie desktop I am used to (example: black background and generally
strange looking). And it also seems like it decided that my keyboard
is a US layout, which is completely wrong of course.

When I launched Lazarus it shows up pretty well, but cannot be moved
inside the X window. And the X window itself cannot be moved on my
Win7 desktop either...
All-in-all it does not give me much improvement

Now I have to figure out how to get it off of my Win7 desktop...
It does not act as any other Windows application does regarding the
windowing.
Shutting down the Putty session eventually removes the X window but it
is still present on my taskbar but won't maximize anymore.
Will have to use Task Manager.


Later:
I also tried the RDP solution linked to from the page above:
http://www.raspberrypiblog.com/2012/10/how-to-setup-remote-desktop-from.html

This does not have the unfamiliarities of the X-ming solution but
instead the key eating was present there too...
So the < and + keys could not be used.
So the exact same keys were affected in the same way, strange eh?

And the clipboard worked even worse than with TightVNC.

Seems like I will have to stick with TightVNC for the time being.

I'm not sure whether this is the same issue as in the bug report, but
for me there has been a problem ever since I use Lazarus on Linux with a
"non mainstream" keyboard layout, which is for several years now. It was
behaving the same with Ubuntu years ago and currently I use a pretty up
to date archlinux, so for me it didn't change because of external libraries.
Dvorak has been mentioned and I'm using Neo (called Neo2 in most linux
distros). For me it is configured as the default layout in X11, tty and
my Xfce settings and I usually don't change it.

The issue for me is that some keys (even some single keystrokes) don't
work at all, do something different, or modifier keys seem to be
ignored, e.g. I can't type the letter 'ä', but strangely 'ö' works.

I have never tried Lazarus via VNC. For me the issue occurs when running
Lazarus just normal on the local X server. But it is only the SynEdit
component, which is affected. Other menus like preferences or
objectinspector work just like they should. And almost all other
programs like gedit, gnome-terminal, firefox, etc. don't have problems
either.

I will go to the RPi forum and ask people there about setting up X for

As I've said multiple times before, you'd do best tunneling one app over 
SSH rather than putting the entire desktop over [any of several ways of 
doing it]. You might find this easiest if you investigated an X11-based 
system o your desktop, rather than Windows... at least while you're 
working out what's possible and what suits your working arrangements.

It doesnt mean that it cant be fixed (or if broken in vnc: worked

And the time check IIRC is there for a reason.
I believe (from what I heard) there are cases where the event for the 
same keystroke can be received again, leading to duplicate input. The 
time field is a way to identify this. The key code can not be used, 
since event handlers can change it, and it would then be received with 
the new value.

I am not sure if the origin of the 2nd event would be the OS or LCL.

As far as I know you do get a X Server implementation for Windows too.
You would simply start that up, use Putty to SSH (with X11 port
forwarding enabled) to the RPi, and run the Lazarus executable on the
RPi. The Lazarus IDE should then appear on your Windows desktop.
Obviously things like "File - Open..." will display the content on the
RPi and not your Windows system - but that is normally desired anyway. ;-)

At least the above is how it works between my X11 based systems.

I can understand complex input as you described, but in my case the
issue was simply typing code in the code editor window. Press one
character (eg: "a") and another character will appear - or nothing appears.

I've gotten used to the issue though. Just restart Lazarus (which is
luckily quick to do) and then Lazarus IDE behaves correctly.

I don't believe that is a new issue in Lazarus though, and not limited
to only VNC connections. For years I've had issues where if I changed my
keyboard layout of X11 via xmodmap, while Lazarus was running, then all
(most) keyboard input in Lazarus is screwed. Other running applications
continue to work fine, but Lazarus not. I have to close Lazarus down and
start it up again before keyboard input works correctly.

I don't know if this relates to VNC, but it might - as VNC (and RDP) can
do keyboard translations on the fly. eg: Me running Dvorak locally,
connecting to a system that has Qwerty setup. VNC and RDP automatically
makes the keystrokes for me, without me having to change the keyboard
layout of the remotely system.


VNC- both the standard xvnc4viewer and krdc as an alternative- has 
problems with some character mappings and combinations. This has long 
been an irritiation to me with both Delphi (on Windows) and Lazarus (on 
Linux or Solaris) since on occasion I've wanted to use a doubleclick 
plus two shift keys to get into a special "maven mode" for debugging 
etc., some combinations quite simply don't work with VNC while they're 
fine with e.g. X11 tunnelled over SSH.


I don't see that as necessarily being a Lazarus problem, but Bo's 
observation that simple text entry fields behave differently from the 
IDE editor- possibly because they don't have hooks for CodeTools etc.- 
is arguably a bug and perhaps should be raised as such on Mantis.


I think that your (Graeme) point about Dvorak etc. keyboards is really 
down to what software converts the keyboard (scan) codes into internal 
X11 codes. I had to dig around a little a few weeks ago when I needed to 
simulate a "Windows" key on a keyboard that didn't have one, but I don't 
pretend to really understand how the various tables etc. work.

[Lazarus] Keys not recognized by Lazarus 1.6 code editor

[Bo Berglund]

I have discovered a strange problem with my Lazarus 1.6 release
installation on RPi2 (Raspbian Jessie) concerning keyboard entries.

When I connect via VNC from my Windows7 PC I can not enter the
characters < or + via the keyboard keys into the Lazarus code editor.
But it is working just fine if I type these characters into a property
of the form like Caption. Or any other tested place in Lazarus
accepting text input.

If I open the Raspbian default text editor there are no problems
entering these characters.

If I connect my monitor and keyboard directly to the RPi (a bit
awkward) then these characters can be entered into the code editor
too.

So what is Lazarus doing inside the code editor that makes it "eat"
some keyboard entries?

Note as I stated above that in all other parts of Lazarus where text
can be typed it records and shows the correct key entries...

On my keyboard the < key is the second key from left in the second row
from the bottom and the + key is the key following 0 on the top
numeric key row (not counting the F-key row).

If I type the + on the numeric keypad it registers correctly.

Is there some key filter in the IDE settings I have inadvertently set
wrong? It must be connected to the Lazarus code editor since
everywhere else keys enter properly.

Also:
Ctrl-C (Copy) does not work in the code editor either. But it works as
expected in Lazarus property editors and other places where text can
be put into the clipboard
Things I copy in Windows7 *can* be pasted in the code editor though.
So this is a one-directional problem.
And in other applications like the text editor copy/paste works
perfectly good.

The encoding of text files depends on what program you used to create

it. Windows applications usually create either system code page or

UTF-8, sometimes UTF-16 LE. Linux apps mostly UTF-8.

Maybe the function GuessEncoding from LConvEncoding can help.

You can use WinCPToUTF8 under Linux too. It simply keeps the UTF-8

there.

You must additionally set

  FConn.Transaction:=FTrans;


 FQuery := TSQLQuery.Create(NIL);
 FQuery.DataBase := FConn; // <== Database property set here!!!
 FQuery.Transaction := FTrans;

WinCPToUTF8 from unit LazUTF8 or CP1251ToUTF8 from unit LConvEncoding

The encoding of text files depends on what program you used to create
it. Windows applications usually create either system code page or
UTF-8, sometimes UTF-16 LE. Linux apps mostly UTF-8.
Maybe the function GuessEncoding from LConvEncoding can help.

You can use WinCPToUTF8 under Linux too. It simply keeps the UTF-8
there.

In which modul are
 WinCPToUTF8 or CP1251ToUTF8? (   Error: Identifier not found "WinCPToUTF8")  

I want to make my application both on Windows and Linux.
In Linux can I use the same functions or have any other? 
 
Is SysToUtf8 works on Linux? If I use encoding UTF-8 for the fail it works.

Kamen

SysToUTF8 was changed, because in the majority of cases it was used for

talking to the RTL.



You can use WinCPToUTF8 or CP1251ToUTF8 instead.

I always install Lazarus as the user and inside user home where file
permissions are OK:
For example: ~/dev/lazarus/1.6

THen there are no problems when Lazarus needs to rebuild etc.

[Lazarus] SQLDb and TSQLQuery usage for MSSQL database...

[Bo Berglund]

In my previous thread I received help that made it possible for me to
connect from my RPi2 to an MSSQL database server on a Windows server
in the network using the TMSSQLConnection component.
So the connectivity seems fine.
(Using FPC 3.0.0 and Lazarus 1.6)

Now I have a different problem regarding usage of the TSQLQuery
component, which does not currently work as expected:

I have read the tutorial in
http://wiki.freepascal.org/SqlDBHowto#Example:_reading_data_from_a_table
and tried to use it in creating a DB handler class for the
application.
The basics are as follows:

- Here is the current state of my DB handler class: ---

  TUserDb = class
  private
FConn: TMSSQLConnection;
FQuery: TSQLQuery;
FTrans: TSQLTransaction;
FDatabase,
FDBserver,
FDBLogin,
FDBPasswd: string;
FDBSet: boolean;
FLoginSet: boolean;
FPwdSet: boolean;
FServerSet: boolean;
FLastError: string;
procedure SetDatabase(AValue: string);
procedure SetLogin(AValue: string);
procedure SetPasswd(AValue: string);
procedure SetServer(AValue: string);
  public
property Database: string read FDatabase write SetDatabase;
property Server: string read FDBServer write SetServer;
property Login: string read FDBLogin write SetLogin;
property Passwd: string read FDBPasswd write SetPasswd;
constructor Create;
destructor Destroy; override;
function OpenConnection: boolean;
procedure CloseConnection;
function GetPasswordFile(var slPWD: TStringList): boolean;
  end;


implementation

{$R *.lfm}

{ TUserDb }

procedure TUserDb.SetDatabase(AValue: string);
begin
  if FDatabase=AValue then Exit;
  FDatabase:=AValue;
  FDBSet := true;
end;

procedure TUserDb.SetLogin(AValue: string);
begin
  if FDBLogin=AValue then Exit;
  FDBLogin:=AValue;
  FLoginSet := true;
end;

procedure TUserDb.SetPasswd(AValue: string);
begin
  if FDBPasswd=AValue then Exit;
  FDBPasswd:=AValue;
  FPwdSet := true;
end;

procedure TUserDb.SetServer(AValue: string);
begin
  if FDBServer=AValue then Exit;
  FDBServer:=AValue;
  FServerSet := true;
end;

constructor TUserDb.Create;
begin
  FConn := TMSSQLConnection.Create(NIL);
  FTrans := TSQLTransaction.Create(NIL);
  FQuery := TSQLQuery.Create(NIL);
  FQuery.DataBase := FConn; // <== Database property set here!!!
  FQuery.Transaction := FTrans;
end;

destructor TUserDb.Destroy;
begin
  FQuery.Free;
  FTrans.Free;
  FConn.Free;
  inherited Destroy;
end;

function TUserDb.OpenConnection: boolean;
begin
  Result := false;
  if not (FDBSet and FServerSet and FLoginSet and FPwdSet) then
  begin
FLastError := 'Missing connection parameter';
Exit;
  end;
  if FConn.Connected then
 CloseConnection;
  FConn.DatabaseName := FDatabase;
  FConn.HostName := FDBServer;
  FConn.UserName := FDBLogin;
  FConn.Password := FDBPasswd;
  try
FConn.Open;
Result := FConn.Connected;
  except
on E: Exception do
  FLastError := E.Message;
  end;
end;

procedure TUserDb.CloseConnection;
begin
  if FConn.Connected then
FConn.Close(true);
end;

function TUserDb.GetPasswordFile(var slPWD: TStringList): boolean;
var
  sSQL,
  sLogin,
  sPwd,
  sCryptPwd,
  sDup: string;
  slCheck, slFile: TStringList;
begin
  Result := false;
  sSQL := 'EXEC SelectPwdEntries';
  slPWD.Clear;
  slCheck := TStringList.Create;
  slFile := TStringList.Create;
  sDup := '';
  try
try
  if not OpenConnection then
  begin
Exit;
  end;
  FQuery.SQL.Text := sSQL;
  FQuery.Open; //<== Error exception here!!!
  if not FQuery.EOF then
  begin
FQuery.First;
repeat
  sLogin := FQuery.FieldByName('LoginName').AsString;
  sPwd := FQuery.FieldByName('Passwd').AsString;
  sCryptPwd := FQuery.FieldByName('CryptPwd').AsString;
  if (sLogin <> '') and (sPwd <> '') and (sCryptPwd > '') then
  begin
if slCheck.IndexOf(sLogin)<0 then //no duplicates
begin
  slCheck.Add(sLogin);
  slFile.Add(sLogin + ':' + sCryptPwd);
end
else
  sDup := sDup + #13 + sLogin;
  end;
  FQuery.Next;
until FQuery.EOF;
FQuery.Close;
CloseConnection;
if sDup <> '' then
  ShowMessage('Duplicated logins!'#13#10 + sDup);
slPWD.Text := slFile.Text;
Result := true;
  end;
except
  on E: Exception do
FLastError := E.Message;
end;
  finally
slCheck.Free;
slFile.Free;
  end;
end;


 On the form I have these related functions ---


procedure TForm1.FormClose(Sender: TObject; var CloseAction:
TCloseAction);
begin
  FDBHandler.Free;
end;

procedure TForm1.FormShow(Sender: TObject);
begin
  FDBHandler := TUserDb.Create;
end;

procedure TForm1.btnGetPwdFileClick(Sender: TObject);
var
  slPwd: TStringList;
begin
  FDBHandler.CloseConnection;
  FDBHandler.Database:= '';
  FDBHandler.Server:= '';
  FDBHandler.Login:= '';

Probably your installed compiler (Free Pascal) and the Lazarus binaries
do not match.
How did you install Lazarus?

Running and testing self written programs is risky, doing it as root
can do havoc to your system.

We provide newer Ubuntu packages (DEB) for FPC and Lazarus:
https://sourceforge.net/projects/lazarus/files/?source=navbar

You can use WinCPToUTF8 or CP1251ToUTF8 instead.

You really shouldn't have lazarus installed in such a "shared" location
on your system. A normal user doesn't have write access, and no, I
wouldn't recommend you running Lazarus as root.

Uninstall and maybe use a different installation method so you can
choose the destination directory. I recommend installing Lazarus in
~/devel/lazarus/ for example - where you have write access. Then you
shouldn't have this problem again.

FPC is not so much a problem installed in a shared location, because
normally you don't need to rebuild FPC. But Lazarus IDE is another story
(eg: every time you install new components in the IDE, it requires a
rebuild).
