* File Name : MCISTRNG.C
*
* Description : This file contains the C source code required for the
* MCISTRNG sample program. This program can be run in three ways.
*
* 1. The user enters MCI String commands from a combination box
* and presses the Send pushbutton.
* 2. The user can enter a batch file which has a series of valid
* commands (one command per line) at the command prompt.
* 3. The user can open a batch file by selecting "Batch file"
* push button.
*
* The command is sent to the MCD and the string is placed in the
* combination box's list box.
*
* The MCD will take the MCI String Command and process it into
* the correct MCI Commands. Depending on the MCI String
* Command the MCD will sent MCI Notification messages back to
* the application. These messages will be filtered as per the
* user's instructions so that only certain messages will be
* shown.
*
* Concepts : This sample program will show how the MCI String interface
* is used. Basically, the use of the interface involves
* sending MCI String Commands to the MCD, and handling the
* MCI Notification messages that are received by the Call
* Back window.
*
* MMPM/2 API's: List of all MMPM/2 API's that are used in
* this module
*
* mciSendString
* mciGetErrorString
*
* Required
* Files : mcistrng.c Source Code.
* mcistrng.h Include file.
* mcistrng.dlg Dialog definition.
* mcistrng.rc Resources.
* mcistrng.ipf Help text for the Main Dialog.
* makefile Make file.
* mcistrng.def Linker definition file.
* mcistrng.ico MCI String Icon.
