can LAMW work with BLE devices?

I haven't been able to implement it yet ... BLE is a difficult task for me .... (I don't really understand the subject ...)

Edited:  Can you do some test? (I dont have a BLE device...)

Hi,
Is there support for TCheckboxes and TComboBoxes as cell editors in FPSpreadsheet? If no, is it planned?
Thanks

IBX for Lazarus.
Have you tried this? If yes, what is your overall evaluation?

Yes, that is the reason I recommended it.

I have several Firebird 3 applications that depend on it. I have no complaints about the library. In fact, I think it is excellent. The developer participates in these forums, and is very responsive to bug reports. And, it has good documentation.

Sadly pascal does not have named loops like Ada, but in your case break should work, because it breaks the most inner loop (so your b loop):
Code: Pascal  [Select][+][-]
  1. procedure MyProcedure;
  2.  var a,b,c:integer;
  3. begin
  4.   for a:=0 to 10 do
  5.     for b:=0 to 10 do begin
  6.      c:=StrToInt(inputbox());
  7.      if c=3 then Break;
  8.    end;
  9. end;
Other possibility: merge loops, there is no need for 2 for loops here:
Code: Pascal  [Select][+][-]
  1. a := 0;
  2. b := 0;
  3. while a <= 10 do
  4. begin
  5.   Inc(b);
  6.   if b > 10 then Inc(a)
  7.   else
  8.   begin
  9.     c := StrToInt(inputbox())
  10.     if c = 3 then b := 0;
  11.   end;
  12. end;

If you want to use goto:
Code: Pascal  [Select][+][-]
  1. var a,b,c: Integer;
  2. label bLoop;
  3. begin
  4.   for a := 0 to 10 do
  5.   begin
  6. bLoop:
  7.     for b := 0 to 10 do
  8.     begin
  9.       c := StrToInt(inputbox());
  10.       if c = 3 then goto bLoop;
  11.     end;
  12.   end;
  13. end;

Databases / DB accessing application staying in memory
« Last post by egsuh on Today at 01:38:03 am »
Can I write such a program (or library)?

What I want is keeping logged to a database, and doing DB-jobs (inserting, updating, viewing, deleting records, etc.) when requests come in. This could be a DB server in server-client relationship.

I need this function for web server.  My web-server program has run welll without any problem in CGI mode. But CGI is supposed to re-connect at every request. Up to now, the requests are not so many, and my (very low grade PC machine  :D) server had no problem in handling them.

FastCGI approach (or ISAPI/NSAPI of Delphi) is supposed to be a solution, as the application remains in the memory and responds to requests. But currently Free Pascal's fCGI is not perfect (which Michael Van Canneyt adimitted --- I have no intention to blame him for any reason. I always appreciate his contributions.)

I'm looking for various approaches. I think one possibility is to separate a database server from web-server on the same machine (and maybe later have to separate). 

Sometimes I wonder that CGI modules remain in memory (i.e. not disposed after responding to a request) for a while. IIS of Windows itself may be doing something --- I have to check this further by leaving log information to the database, etc.   If this is true, CGI approach is good enough.

How can I achieve this with Lazarus?   (on Windows 10).

LCL / Re: Safe to use tvirtualgrid?
« Last post by jamie on Today at 12:43:55 am »
Ok, I looked at Delphi and notice I couldn't find that in the listing of possible classes already defined and I don't like recreating the wheel when there is code already in the pile that can be implemented.

 The TVirtualGrid just happens to have the layout I need although the names of the fields are not exactly what I pictured but it will do..

 The other alternative was using a collection which to me looks like it could turn into a fragmented heap nightmare .

 Thanks.

Hi!

Use the whole syntax that Pascal offers:

Code: Pascal  [Select][+][-]
  1. procedure MyProcedure;
  2.  var a,b,c:integer;
  3. begin
  4.   for a:=0 to 10 do
  5.   begin    
  6.    b := 0; c := 0;
  7.   while (b  <=10) and (c<>3) do begin
  8.      c:=StrToInt(inputbox());
  9.      inc(b);
  10.    end; // while
  11.  end; // for
  12. end;
  13.
