Proigryvanie Video and Audio files in program on Access

Sometimes can be necessary to reproduce some sound file or view видеоклип from program, written on Access. Certainly, possible use some ready external subroutine and start her(it) through Shell. But herewith we lose the possibility of reproduction control from program Access.

On-this, I have solved to search for some ActiveX-component, which coped with this task. One of the main criterion of the selection was бесплатность. Not each can afford выложить round amount for commercial product. In a certain time I have found RVK.Viewer, which is free ActiveX-component, giving for developer following possibilities:

• Viewing the graphic files BMP, JPEG, GIF and TGA.
• Viewing video-files MPEG-1/2, AVI and Windows Media.
• Reproduction audio-files WAV and MP3.

This element is easy integrated in program, designed in office applications on VBA, including Access. Offer your attention a variant плеера, founded on ActiveX-component RVK.Viewer. Pleer allows to produce:

• Viewing video-files MPEG-1/2, AVI and Windows Media.
• Reproduction audio-files WAV and MP3.

In плеере are not used nor what other ActiveX elements except RVKvwr.dll.

After start on screen will be a form with black rectangle - a screen RVKvwr and management body.
To load the file on processing, necessary to choose this file. For this on the right on field "File" press the button with "..." and in appeared window of the choice of the file choose necessary.

After boot, the file will is analysed on contents, and on the right on копок control appear the inscription "Video" and "Audio", or one of them. Two numbers appear Under these inscription, prepared "/". The Right number shows current time of the reproduction, but left number - a size of the file.

Management body "Transition are found Under RVKvwr in begin", "Reproduction", "Pause", "Closing the input file", "Avtopovtor".
Under floor with filename are found button "Info" - removes the short information about плеере, button with scene track record - disconnects and includes the sound, step-like regulator to loudness - allows to adjust the db level from 0 before 100% with at a walk 25%.

And the last button "Output" with door and arrow closes the form.
