@Mahdi Safsafi Reading your comment again a question. If a component is on the pallet it is loaded, right?

P.S this is part of my tool

@Mahdi Safsafi i would like to elaborate a little. It all started with this So dave helped a lot and i have what i needed But during the use of the tool i had what you fixed. But then i found that some components i do not show and this is where the last problem stand

@Mahdi Safsafi you are wrong. Unless I did not understand you. We are talking about components being on the component/Pallet. Once you register it I should see it inside the package. simple. I have made along time ago BPL analyzer and more. It scans all the bpl in the Delphi directory and analyzes them. see the pictures. Your component is in the bpl.(the package). The program should be able to read the package simple. In my case, it does not. Something happens that Delphi did not foresee. Maybe I am wrong. So now I am looking for a DIFFERENT way to read the packages.

I guess you did not understand the situation. 1. I install a new component. 2. it is on the list 3. package full with component 4. Close program Delphi. 5. open Delphi. 6. rerun my program. 7. see component on a pallet 8. package empty

---------dockingformpackage.bpl Empty no component INSIDE In my case, some installed packages show empty although they have components inside and that is the problem and this is the stament if PackageServices.GetComponentCount(PackageCounter) = 0 then

Use my last demo because the old one are not perfect You will get a list of similar txt This is an empty package ---------xxxxxx.bpl

Here it is my last demo to see how many packages are empty DockingForm (2).zip

@Kas Ob. I am too professional to leave this point. After installing and seeing the component I close the Delphi program and reopen. This is when the package is empty. P.S I have a new demo with a button to initialize. The problem is that restart Delphi the packages are empty. !!! If you want I can put here the source it is 2 more lines. See my last comment

I have created a text file of the components and there packeges. Where there is no component in the package see ---------zcontrols_d.bpl and more. if PackageServices.GetComponentCount(PackageCounter) = 0 then s.Add('---------'+PackageServices.PackageNames[PackageCounter]); But one can see in the component tab the components and also on the pallet So i am trying to investigate but i am almost at the end. tst.txt

@Mahdi Safsafi and others Well, I just installed a new component on my D10.2.3, and after closing the Delphi program and reopening it does not show on my list !!. Although it is on the pallet. So it is the Delphi program. !!!! So now for the questions 1. is there another way to get the component list? beside PackageServices := BorlandIDEServices as IOTAPackageServices; and for PackageCounter := 0 to PackageServices.PackageCount - 1 do 2. is there a max quantity for components? I have many. P.S @Mahdi Safsafi I just installed your ZControl and it too disappeared

Oh no not again . Restart Delphi stop showing in the list the component. I will manege.

OK to sum it . I do not understand the IDE. I recompiled and reinstaled the component and now it shows on the list. Even it was on the pallet it did not show. Not my fault. As for my first problem the @Mahdi Safsafi solution helped a lot. Thanks

Sorry for the bother but it mite be me Thanks for any help

I hop i do not bother someone but this buffels me https://github.com/digao-dalpiaz/Dam this is not on the list although it is on the pallet And if this is the case may be some other components too. procedure GetAllClass; // var Coreide: THandle; Delphicoreide: THandle; LGlobalPackagesPtr: Pointer; LDesignPackages: TDesignPackages; LIDEDesignPackage: TIDEDesignPackage; LRegModule: TRegModule; LRegClass: TRegClass; LIDEDesignPackageCount: Integer; LRegModuleCount: Integer; LIndex: Integer; I: Integer; J: Integer; PackageServices: IOTAPackageServices; PackageCounter: Integer; s: TStringList; begin s := TStringList.Create; // Result.Clear; PackageServices := BorlandIDEServices as IOTAPackageServices; Assert(Assigned(PackageServices)); { --- Move me outside --- } // adapt 260 suffix according to your Delphi version. Coreide := GetModuleHandle('coreide250.bpl'); Delphicoreide := GetModuleHandle('delphicoreide250.bpl'); LGlobalPackagesPtr := GetProcAddress(Coreide, '@Pakmgr@Packages'); DesignPackagesGetPackages := GetProcAddress(Coreide, '@Pakmgr@TDesignPackages@GetPackages$qqri'); IDEDesignPackageGetCount := GetProcAddress(Delphicoreide, '@Pascpppakmgr@TIDEDesignPackage@GetCount$qqrv'); IDEDesignPackageGetModules := GetProcAddress(Delphicoreide, '@Pascpppakmgr@TIDEDesignPackage@GetModules$qqri'); RegModuleGetCount := GetProcAddress(Coreide, '@Pakmgr@TRegModule@GetCount$qqrv'); RegModuleGetClasses := GetProcAddress(Coreide, '@Pakmgr@TRegModule@GetClasses$qqri'); Assert(Assigned(LGlobalPackagesPtr), 'LGlobalPackagesPtr not assigned'); Assert(Assigned(DesignPackagesGetPackages), 'DesignPackagesGetPackages not assigned'); Assert(Assigned(IDEDesignPackageGetCount), 'IDEDesignPackageGetCount not assigned'); Assert(Assigned(IDEDesignPackageGetModules), 'IDEDesignPackageGetModules not assigned'); Assert(Assigned(RegModuleGetCount), 'RegModuleGetCount not assigned'); Assert(Assigned(RegModuleGetClasses), 'RegModuleGetClasses not assigned'); { --- End Move outside --- } if Assigned(LGlobalPackagesPtr) then begin for PackageCounter := 0 to PackageServices.PackageCount - 1 do begin if PackageServices.GetComponentCount(PackageCounter) > 0 then begin LDesignPackages := TObject(PPointer(LGlobalPackagesPtr)^); LIDEDesignPackage := DesignPackagesGetPackages(LDesignPackages, PackageCounter); LIDEDesignPackageCount := IDEDesignPackageGetCount(LIDEDesignPackage); LIndex := 0; // Compeginonent Index. for I := 0 to LIDEDesignPackageCount - 1 do begin LRegModule := IDEDesignPackageGetModules(LIDEDesignPackage, I); LRegModuleCount := RegModuleGetCount(LRegModule); for J := 0 to LRegModuleCount - 1 do begin // if LIndex = ComponentIndex then begin LRegClass := RegModuleGetClasses(LRegModule, J); s.Add(TClass(PPointer(PByte(LRegClass) + 4)^).ClassName); // exit; end; Inc(LIndex); end; end; end; end; end; s.SaveToFile('c:\tst.txt'); s.Free; end; can some one install and help ? just add above to my test package and in Initilize just call GetAllClass;

Thanks

@Mahdi Safsafi Just for general knowledge why there is a difference between the getting of the component from the toolbar and from the package. Since every component is going from a search through the bpl again and again which is time-consuming. I guess I can leave most of the initialization outside of GetClass2 but still a lot of iterations. So again why the difference? in nil In the package the class is different?

Thank i will try yours again

I have made a very simple DEMO reading from the component bar (it does not have to show) In the end, it saves components to a txt file. Very simple. See how many components are NIL !!!!! DockingForm (2).zip And that is my problem The same problem with Tool Pallet although there is a discrepancy between the two

I am preparing a very simple test

First I am using D10.2.3. All "Normal components are read" But try to install the above component and am i wrong? Further more try to do if xx<>nil then qqqqq.... else <<<< catch here and see I did catch by InstalledComponentName := PackageServices.ComponentNames[PackageCounter, ComponentCounter]; and lastly I xx := GetClass(InstalledComponentName); where xx: TPersistentClass; The class name is not the problem

@Mahdi Safsafi Well, not good news. I have used your suggestion it does not work in my case. Well, let me explain. I am using this guy component. https://github.com/digao-dalpiaz/Dam It worked great and I have no complaint BUT it represents a section of components that reading them from the IDE get nil for classes. They seem to register OK and show on the pallet and are usable. So that is the problem. in your case, I used TPersistentClass(LClass); like that. Maybe this is the problem.? Since I have to use TPersistentClass as I am taking an old program and making it an EXPERT. So the question is if TPersistentClass is the problem as I am using GetClass or your Lclass. Any idea? Maybe I can tackle my problem differently. at the end I use this RegisterClasses(MyArray); where MyArray is TPersistentClass. This is why the above Hold my question something fishy Ok I return to my basic question 1. Reading from component toolbar NO DAM 2. Reading from tool pallet YES DAM in this case still DAM shows nil !!! DAM can be used from both Crazy IDE ????

I have an expert with form TForm1 = class(TDockableForm) I drag the form to the left and pin it. Now I have a tab of my expert shown on the left. When I close the project the tab disappear even saving the desktop does not help. Do I need to add something on my software? Using D10.2.3

@DanielIt took a while to investigate. I downloaded the demo Docking form It has all as per your suggestion. However When I dock the form it works. While the IDE is open it works. Changing a project it works. BUT closing Delphi d10.2.3 and reopening it did not save the position (it wasn't docked any more) and I had to redock. Saving the desktop did not help. Is it suppose to be like that? Any suggestion? DockingForm.zip Well docking to the right mite work. To the left NO. Docking to the left and reopening Delphi it docks to the right. Funny Delphi IDE it docks to the right this is why I thought it dose not work. I had to dock twice. dock close dock. Now it works on the left too. Very unreliable.

@Uwe Raabe It mite work thanks xx:TPersistentClass; xx:=GetClass(PackageServices.ComponentNames[PackageCounter, ComponentCounter]);
