Re: [Lazarus] How TDBGrid works
Thanks. So what is the best way to provide those 100 to 1100 record at least without Dataset calling AfterScroll event? I want to not make any event while scrolling my custom Grid so other connected DB controls change their values otherwise while Im scrolling my custom grid it will cause calling all connected DB controls to update their values.

Re: [Lazarus] How TDBGrid works
Thanks, It seems I should explain better. For RecordCount you are right and it seems DBGrid doesn't know correct number either otherwise it should has a better scroll size. I want to do something like DBGrid and for that I want to get only a part of data for example record 1000 to 1100 and for that I can set BufferCount to 100 but in this case I should navigate dataset to record 1000 to get these value but I prefer to not change RecNo and use something like DataLink's ActiveRecord that changes record you want without changing RecNo of Dataset. So if I have 1 Dataset that is fully load all 1500 record can I just print records from 1000 to 1100 without changing RecNo?

Re: [Lazarus] How TDBGrid works
Jesus, In that demo if I set BufferCount to 9 always get 9 records and even Query.RecordCount will be 9 even result is more. How can I get real count?

It need a simple change and it will compile but it has a uncompleted demo that I cant compile and I dont have clue how it works and some test shows weird behavior so I want to ask : What is the best choice to have a good DB tree view? is there any component available or should I write code for every DB situation in my projects? Also a good ability of VirtualTree is that t can be used as a grid and the best grid I know is KGrid but it aslo have a not beautiful/weird DB behave and ic compare of VirtualTree abilities and speed will seems not a good choice. So all questions in one : Is there any good DB TreeView/Grid in Lazarus world?

[Lazarus] Easy to use memory dataset and TMemDataset problems
Hi,
I want a memory dataset like VirtualTable [1]and really I cant
understand what are these bufdataset and memdataset and wiki[2] page as
I cant make bufdataset works without a file. I want an easy to sue
memory dataset without any file usage.
Yes there is a way to use TMemDataset like this as @Thaddy said:
> program memdbtest; {$apptype console}{$mode objfpc} uses db,memds;
> var MemDb:TMemDataset; begin MemDb:=TMemDataset.Create(nil); try
> MemDb.FieldDefs.Add('NAME',ftString,20); MemDb.CreateTable;
> MemDb.Open; MemDb.Append; MemDb.FieldByName('NAME').Value:='Free';
> MemDb.Post; MemDb.Append;
> MemDb.FieldByName('NAME').Value:='Pascal'; MemDb.Post;
> MemDb.SaveToFile('MemDb.txt'); // as long you do not close, you don't
> have to save finally MemDb.Close; MemDb.Free; end; end.
But as you can see it use memds unit that CodeTools has problem with
memds unit and also it will replace it with MemDataSet unit that has a
different TMemDataset without CreateTable option.
Also Wiki [3]says that BufDataset is a better choice but is it really?
and is it a choice for using as a memory dataset?how?

[Lazarus] Guess the problem with Heap
Hi, Im working on one of my projects and tried to make a release version, so I used shortcut button in build modes and add release mode but when I compile and run I get SIGSEGV error when main form want to be create. After many tries I found out that if I check "Use Heaptrc unit" in project debugging option program will run correctly even it is release mode so there is no debug info. So simple : If I check that option and use Heaptrc, no problem and if I unchecked it, error . Its a old project and I dont remind any code I write about heap so I cant find the problem so I want to ask anyone can guess what code can make such problem?

[Lazarus] Libraries delayed loading
Hi, I have many libraries and all the wrappers are static and I cant change all of them to dynamic loading but I want to put them in different folder my program root. It seems there is "delayed" option is in Delphi that give you time to SetDllDirectory and change the path before loading dll. And as I checked Lazarus hasnt this option so I want to ask is there any alternative way except changing all wrapper to dynamic loading for loading dll from different place without changing system path. http://wiki.lazarus.freepascal.org/Dynamically_loading_headers#Solution_of_Delphi_2010_.28modifying_compiler.29 http://stackoverflow.com/questions/15240729/delphi-dll-organization-static-and-dynamic-loading Regards, Ara -- http://www.fastmail.com - Access your email from home and the web -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Setting environment variables for libraries
Hi,
I have many libraries (dll,so) and they come with wrappers with constant
library path and file name. I want to move these libraries to a specific
folder and load from there so one way I know is to change them and load
them dynamicly but I cant do it every time new library version came out
with new changes.
So I hope there be a some kind of virtual environment variables so when
I call x.dll, it search also there and conenct to it like when you put
dll in system32 in windows and your program will find it. I dont want to
change system environment variables because these libraries will use
only in my program.
I tried something like this:
> program project1;
>
> {$mode objfpc}{$H+}
>
> uses {$IFDEF UNIX} {$IFDEF UseCThreads} cthreads, {$ENDIF} {$ENDIF}
> Interfaces, // this includes the LCL widgetset Forms, Unit1 { you

As you can see project file uses Unit1 and it uses BASS and it wants to
call dll before our path changes! :| How can I solve this?

[Lazarus] Getting MySQL process output
[Cross posted on forum so if you want answer there :

Hi,
I want to play with MySQL process and get what ever it write to console
so I write this code:
> Process := TProcess.Create(nil); with Process do begin
> Executable := 'C:\Program Files (x86)\MySQL\MySQL Server
> 5.5\bin\mysql.exe'; with Parameters do begin Options :=
> [poUsePipes]; Add('-u'); Add('root'); Add('-p');
> end; Execute; while Process.Running do
> Memo1.Lines.LoadFromStream(Process.Output); end;
But the problem is that this will freeze because there is no output but
console window write :
> Enter password:
How can I get this in my application and all others?
As I said I want to work with MySQL executable and read from and write
in it, So I dont want to use its library or any other DB component.

[Lazarus] Strange application startup problem
Hi, Today I open one of my applications and start working on it and made many changes and hit the run but it will immediately crash! So like a programmer I add a break poit on my main form create and no it will not run and crash will happen. So I add another break point to first line of application: > begin RequireDerivedFormResource:=True; // Here > Application.Initialize; Application.CreateForm(TFormX, FormX); > Application.Run; end. the lpr file is made automatically but even the first line will never run! It was strange so I delete CreateForm line and run again : > begin RequireDerivedFormResource:=True; // Here > Application.Initialize; Application.Run; end. And now everything work! So the problem is form but what? I add a new clean form and make it main form like this : > begin RequireDerivedFormResource:=True; > Application.Initialize; Application.CreateForm(TForm1, Form1); > Application.Run; end. And run and everything OK. So add a button on Form1 and write : > Application.CreateForm(TFormX, FormX); FormX.Show; And again crash without even running the line in button or clicking it. Project is in default mode (made from lazarus and I every debug mode is on and I checked default debug mode ) and nothing, I also uncheck Win32 target platform so maybe it show any message in CMD but nothing. This program is bug and I cant share the code or forms and I dont know what was changed this and I can go back,I just need a debug info. So anyone has a clue on what is the problem or how find it?

Re: [Lazarus] Fast GUI
> Obviously, if you want non standard speed, you need to consider non standard complexity. Yes I think like this.As I guess your products are not for end user client so you could use flash without any problem and in my case I want it for some special case and clients so making an special GUI on OpenGL can be an answer because as I said in this GUI there is many image processing and the best I know is OpenGL. But I be happy to know any other solution or a GUI made already.

Re: [Lazarus] Fast GUI
> First of, everything concerning glBegin and friends is ancient stuff, > don't touch them. Don't touch glMatrix* or anything like that, too. Do it on your own (even in JS if you use WebGL). In short: Do the matrix math on the CPU, use the most optimal vertex submission mechanism supported by the targeted version (vertex arrays, VBOs, etc.) and use shaders. Second, every platform has its own flavor of OpenGL: OpenGL for the Desktop, OpenGL ES on mobile and WebGL for the browser. All are similar and yet quite different. All have their own versions and the associated problems. Use OpenGL only if you need its features and then pick your platform and don't try to handle them all in one software. OpenGL is not easy to handle and you really have to dive in deep to make the most of it. You can do a lot of stuff really fast but the API is very old and it shows more and more. You have very little direct control of your graphics hardware and moving data to/from the card is cumbersome. Personally I am waiting for the successor of OpenGL (Vulkan) which does away with the multiple platform versions (Normal, Web, ES), unifies them and is stated to give you much more control of the hardware. I am sure things are not getting much easier in the high speed graphics department but a lot more organized and hopefully better to maintain. R. > Very interesting point about OpenGL and Vulkan.Thanks. By the way do you know any implementation of OpenGL or Vulkan for GUI in pascal for my recent research?

Re: [Lazarus] Fast GUI
> He had used OpenGL to do the GUI for a project (as he had found by > testing that this was the fastest solution). Exactly. I dont know why but I am fascinated about fast GUIs. I am not a professional game developer but for my projects sometimes I need animations and image processing and Im tired of making a graphical component or a especial painter for a case and want to know is there any work available or it is a sane way to make all of my components from OpenGl or something like this and even used OS theme for my view like getting windows 8 draw for a button but make it as a texture and give it to my imaginary button component. As I said I saw this in Firemonkey .It even make DBGrid 3D! I dont need 3D component but I need fast accelerated OpenGL or something like this for my custom GUI.

Re: [Lazarus] Fast GUI
> That's true but something like 2.0 or 3.2 can most likely nowadays be > reasonably targeted. If you go 1.2 it should work everywhere. On phones you can offen use the current version as people upgrade their phones often. Often more problematic are different driver versions and their bugs. If you want to really handle all versions it gets really cumbersome as you have to implement different render paths as the most optimal path differs greatly between OpenGL (major) versions. Hopefully things get better with Vulkan. > But as I read about this a problem is for example in Android phones their support OpenGl ES and taht is diffent to OpenGL like does have glBegin glEnd and it can be kind of problem? It seems you have experience about this?What you think?

Re: [Lazarus] Fast GUI
Thanks Michael,Martin,Reimar and Ondrej. As you said martin it is not easy to use but give you very good performance.I tested it with BGRABitmap OpenGL and it can be very good. But it can have many problems like making text box or memo or whatever. I know there are GUI components with OpenGL even with Pascal but I couldnt test anyone and want to know is there any one here test them or have experience in this field or not. Martin is mse support transparent text box or these component with OpenGL? As I remember you said that mse use no handle per control so what mse do for text component or lists?
