my Lazarus IDE does not start any more
« on: February 09, 2023, 11:41:12 am »
My Lazarus 2.2.4 does not start any more.
And I cannot re-compile, because the error-message makes the system think "exe in use".
What can I do? Everything is blocked here.
  :'( :'( :'( :'( :'(

When Lazarus is closed, go into your Lazarus folder, there is a file called "lazarus.old.exe" what should represent the last working version of your build.
Rename that file to "lazarus.exe" and launch. (for safety create another backup of your current "lazarus.exe" before doing it...)

Restart the PC, its Windows. And sometime a exe can be blocked by the AV. So look after the restart if you see something in the Logs.

And what was your last action before ?!

Thank you so much!
I restarted my operating system (Win 7 within a VMWare VM) and it works again.

The problem must have had more effected than the lazarus.exe.
Probably it touched the system itsself.

What I have done?
Not quite sure, but pretty sure (I will not retry):
I started the project, which shall do my ping for the test of the internet-connection.

I re-upload it again.
Does not look dangerous at all.

► ► ► CAREFUL, do not open the project without reading this thread!

No issue with your sample on my Win-11 (real PC)...

Found the following code in an internet search for "ping lazarus" (https://www.lazarusforum.de/viewtopic.php?t=10095). It is windows-only, but does not use any third-party libraries (only the Jedi translation coming with FPC):
Code: Pascal  [Select][+][-]
  1. uses
  2.   Windows, jwaIcmpApi, jwaIpExport;
  3.  
  4. function Ping(IP:string; TimeOut:Cardinal):Boolean;
  5. var
  6.   hICMP : DWORD;
  7.   pierWork : PICMP_ECHO_REPLY;
  8.   dwSize : DWORD;
  9.   Class1: String = '';
  10.   Class2: String = '';
  11.   Class3: String = '';
  12.   Class4: String = '';
  13.   i,j : Byte;
  14. begin
  15.   Result:=False;
  16.   j:=1;
  17.   for i:=1 to Length(IP) do begin
  18.     if IP[i]<>'.' then begin
  19.       case j of
  20.         1: Class1:=Class1+IP[i];
  21.         2: Class2:=Class2+IP[i];
  22.         3: Class3:=Class3+IP[i];
  23.         4: Class4:=Class4+IP[i];
  24.       end;
  25.     end else
  26.       Inc(j);
  27.   end;
  28.   hICMP := IcmpCreateFile;
  29.   if hICMP = INVALID_HANDLE_VALUE then exit;
  30.   try
  31.     dwSize := SizeOf(ICMP_ECHO_REPLY)+8;
  32.     pierWork := AllocMem(dwSize);
  33.     try
  34.       Result := IcmpSendEcho(hICMP,
  35.         MAKELONG(MAKEWORD(StrToInt(Class1), StrToInt(Class2)), MAKEWORD(StrToInt(Class3), StrToInt(Class4))),
  36.         nil, 0, nil, pierWork, dwSize, TimeOut) <> 0
  37.     finally
  38.       FreeMem(pierWork,dwSize);
  39.     end;
  40.   finally
  41.     IcmpCloseHandle(hIcmp);
  42.   end;
  43. end;
  44.  
  45. procedure TForm1.Button1Click(Sender: TObject);
  46. begin
  47.   if Ping(Edit1.Text, 1000) then
  48.     Memo1.Lines.Add('ok')
  49.   else
  50.     Memo1.Lines.Add('ERROR');
  51. end;
It is working correctly on my system (as I said: Win-11/real PC, as well as Win-7/VirtualBox-VM).

It becomes stranger and stranger.
I did something completely different now: Nothing but copy and paste the method ping of your posting.
Grabbing one of my frames and a class there and added the function "ping" to this class.


So here are the stranger things:

you remember a very old thread?
The code which grabs a pdf file from the internet, converts it to pdf?
This code works very fine since months.
And this code was in the chosen class by good luck.

This code contains 3 lines with nothing special, reading
Code: Pascal  [Select][+][-]
  1.   if FileExists(PDF_FILE) then DeleteFile(PDF_FILE);
  2.   if FileExists(TXT_FILE) then Deletefile(TXT_FILE);
  3.   if FileExists(TXT_FILE) then Deletefile(Change_txt_datei);
 
 
when I add
Code: Pascal  [Select][+][-]
  1.   "uses windows"

the third of these 3 lines produces the error code
Code: Pascal  [Select][+][-]
  1.   frame_margin_.pas(172,59) Error: Incompatible type for arg no. 1: Got "AnsiString", expected "PChar"
  2.  
 
removing the "windows" from the uses clause makes
   
  //  if hICMP = INVALID_HANDLE_VALUE then exit;

not work any more.
Which is not surprising.

Surprising for me - perhaps not for you - is the error message of the third line, which happens, if I add "windows" to the uses clause.

Nicole, I gave you here already a pre-made solution.
Since you have hard problems to integrate it I made it into your source.

I am afraid, you cannot write good solution as quickly, as I destroy them. For today my whole VM was shot. Not just Lazarus, but all of my VM. Brought it to restart in the evening.

Your solution was in my class already.
Did not compile.
This has nothing to do with your solution.
There seems to be a conflict with a different internet-handle-solution I used somewhere else.
It has disadvantages to use things, you do not understand. ;-)

So I searched my last backup and reset all.

Thank you so much for the project!
Nothing of your care is lost. I have an own backup-directory for demos sorted by topic.
Much of this forum is saved there in the meanwhile.
