delphi 7, installed component is hidden on installation
components, custom-component, delphi, delphi-7
Solution
In the registry, under `HKEY_CURRENT_USER\Software\Borland\Delphi\7.0\Palette`, find the entry named `'comp.Hidden'` and edit it to remove the class name of your component (or delete the entry altogether).
Problem
i am working on a component for `delphi 7` and for quick installation without having to touch the `IDE` i am making a simple installer according to this SO answer by Marjan Venema. ``` procedure TForm1.Button1Click(Sender: TObject); var sDelphi7PackageName : string; sDelphi7Path,fileSource,fileDest : string; sDelphi7packBPL,sDelphi7PathMenuBPL : string; begin sDelphi7Path:=ReadRegistryValues('\Software\Borland\Delphi\7.0',FALSE,'RootDir',1,TRUE);{<-- returns the 'C:\Program Files\Borland\Delphi7' } {#1. Install .bpl} sDelphi7BPL:=sDelphi7Path+'\Projects\Bpl\Pack.bpl'; WriteValueToRegisTry('\Software\Borland\Delphi\7.0\Known Packages',FALSE,sDelphi7BPL,'Delphi 7 compo Bpl File'); {<-- writes to the registry} fileSource:=ExtractFilePath(Application.ExeName)+'\Packages\comPack.bpl'; fileDest:=sDelphi7BPL; CopyFile(PChar(fileSource), PChar(fileDest), False); end; ``` This works fine ![enter image description here][2] `C:\Program Files\Borland\Delphi7\Projects\Bpl\Pack.bpl`. but the component installed id `hidden` can anyone tell me how to `unhide` the `component` on installation? EDIT may be useful: 1) i already have the `bpl` file of the component so i am copying directly to the `delphi 7` directory `C:\Program Files\Borland\Delphi7\Projects\Bpl` and modifying the registry `HKEY_CURRENT_USER\Software\Borland\Delphi\7.0\Known Packages`. 2) the `register` procedure of the component ``` implementation procedure Register; begin RegisterComponents('comp', [Tcomp]); end; ```
