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 compiling, you can not find it, it is generally the installation directory of the control.
There are two ways to solve the lib directory of Delphi:
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.
RXLIB installation:
First, in the IDE of Delphi 5, the previous version of RXLIB was reversed, and RxCTL5.BPL, RXDB5.BPL, RXBDE5.BPL, DCLRX5.BPL, DCLRXDB5.BPL, and DclRxBD5.bpl were removed.
Open the RX running package RxCTL5.DPK, press the Compile button in the package window to compile the rxctl5.dpk, then compile the other two Run RXDB5.DPK and RXBDE5.DPK, put the three BPL files after compile In the path, such as
Windows / system, etc.
After compiling running the package, you must install the RX design package into the IDE environment.
Open the RX design period DclRx5.dpk, press the Compile button in the package window, then press the install button to register the design package into the component panel. Install dclrxdb5.dpk and dclrxbd5.dpk with the same method.
Note: Do not save package resources in Delphi ID!
Control delete:
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 packages, That Would Be OK ~
