Control installation Delete Basic Installation:
1. For a single control, Componet -> Install Component ..-> PAS or DCU file -> install;
2. For control packages with * .dpk files, File -> Open (select * .dpk in the drop-down list box) -> install;
3. For the control package with * .bpl file, the install package-> add -> BPL file name;
4. If the above INSTALL button is invalid, try the Compile button;
5. Run Time LIB is added under the package of Packages under Option.
If you can't find it when you compile, you can find it. Generally, there are two ways to resolve:
1. The reverse installed source file is copied into the lib directory of Delphi;
2, or Tools -> Environment Options Add the control source code path to the lib directory of Delphi.
Note: Whether the installed control is adapted to the Delphi version you have.
Control deletion
Remove it in Component / Install Packages.
Select Component / Configure Palette ...
There are two regions of Pages and Components
Double-click the Components area, select the deleted control, and you have the delete button.
But the control provided by the system can only hide, not delete.
Open the package file (* .dpk) where the control is located, remove the file from the control, and recompile the package again.
If you have to delete the entire control package, Project-> Option-> Packages, delete the package, ok ~
