Old package removal

If a previous package of TVideoGrabber is already installed, remove it first:

  • Components | Install Packages

  • Click on "Datastead TVideoGrabber"

  • Click "Remove"

  • Click "Yes"

  • Click "Ok".

  • search from the root of the hard-disk for TVidGrab. and VidGrab. *files and delete them, to be sure that old TVideoGrabber files will not remain in the Borland search paths.

Current package install

  • unzip the package archive to any folder (e.g. c:/vidgrab). Be sure to unzip the full directory structure (using WinZip check "use folder names" ).

  • according to the version of Delphi/C++Builder, copy all the Delphi. or CBuilder. archive files to the Borland\Delphi\Imports or Borland\CBuilder\Imports directory,

  • run Delphi or C++Builder,

  • select Component | Install packages,

  • press the "Add" button,

  • locate the TVidGrab.bpl file in the Borland...Imports directory and select it,

  • Select Open

  • Select Ok

  • Check the "Datastead" tab on the right of the component palette. The TVideoGrabber object should have been added.

Context sensitive help install

  • copy the VidGrab.hlp and VidGrab.cnt archive files to the Borland\Delphi\Imports or Borland\CBuilder\Imports directory,

  • run Delphi or C++ Builder,

  • click "Help", "Customize",

  • select the "Index" tab,

  • click "Edit", "Add files"...,

  • if necessary, select the "Help Files (*.hlp)" file type,

  • locate the VidGrab.hlp file in the Borland...Imports directory and select it,

  • select the "Link" tab,

  • click "Edit", "Add files"...,

  • locate the VidGrab.hlp file in the Borland...Imports directory and select it,

  • click "File", "Save Project",

  • exit OpenHelp.

Install troubleshooting
"TVidGrab.??? file not found" error when compiling or linking the project:
- go to Tools | Environment Options | Library, and check that there is ;$(DELPHI)\Imports (Delphi) or ;$(BCB)\Imports (C++Builder) in the Library path, otherwise add it at the end of the edit field.

  • go to Project | Options | Packages, check "Build with runtime package", go to the end of the packages edit field, remove ";TVidGrab", and then uncheck "Build with runtime package".

Zipped package:

When unzipping the package, the unzip tool must re-create the package's subdirectories.

Using WinZip, be sure to enable "use folder names", otherwise files with the same name will overwrite each other.

Trial versions of Delphi and C++Builder

Trial versions of Delphi and C++Builder come with a different DCU format than the real one.

Trying to use TVideoGrabber and other third-party components with trial versions of Delphi or C++Builder causes Access Violation errors when building a project.
