Delphi control installation and Deletion

General control installation method:
----------
Basic installation
1. For a single control, componet --> install Component... --> pas or DCU file --> install;
2. For control packages with *. dpk files, choose file --> open (select *. dpk from the drop-down list box) --> install;
3. For control packages with *. BPL files, install packages --> Add --> BPL file name;
4. If the above Install button is invalid, try the compile button;
5. Run Time Lib is used together with runtimepackes under packages under option.
If the prompt file cannot be found during compilation, the installation directory of the control is not in the lib directory of Delphi. There are two solutions:
1. The uninstalled source file is exported to the lib directory of Delphi;
2. In tools --> environment optionsSource codeAdd the path to the lib directory of Delphi.
Note: whether the installed control is compatible with your Delphi version.

Control Deletion
Delete the packages in component/install packages.
Select component/configure palette...
There are two regions: pages and components.
Double-click the components area and select the control to be deleted. The delete button is available below.
However, the controls provided by the system can only be hide and cannot be deleted.
Open the control package file (*. dpk), delete the control file, and re-compile the package.
If you want to delete the entire control package, select project> Option> packages, delete the packages, and close the job.
