The VBMCI sample shows how to use the function "mciSendString()" in Microsoft Visual Basic to play multimedia files. This sample also uses the custom control "MMControl" from the MCI.VBX custom-control file to play multimedia files. You may find it easier to use MMControl to manipulate multimedia files than to use mciSendString() commands.

This sample demonstrates only a few of the features of MMControl and a few of the commands strings that mciSendString() can use. The "Microsoft Visual Basic Professional Features," Book 1, contains a complete description of all of the features of MMControl.

You can find more information on command strings that you can send by using mciSendString() in the following resources:

•	"Multimedia Programmer's Reference," included with the Windows 3.1 Software Development Kit (SDK).
•	"Multimedia Programmer's Guide," included with the Windows 3.1 SDK.
•	MCISTRWH.HLP, a Windows Help file included with Microsoft Visual C++, Professional Edition, version 1.X.
•	DK_DOC.MVB or DK_DOC.HLP, Windows Help files included with the Video for Windows Development Kit, version 1.1. (NOTE: These Help files also contain information on the controls in the MCI.VBX and MCIWNDX.VBX custom-control files.)

The "Microsoft Video for Windows Development Kit," version 1.1, comes with a robust sample of how to use the features of the custom-control file MCIWNDX.VBX. This sample is called "VBMCITst".

In addition, there is a helpful topic in both the DK_DOC.HLP and DK_DOC.MVB files titled "Comparing MCIWNDX.VBX to MCI.VBX".
