DOCUMENT:Q98342 14-NOV-1999 [miscsdk] TITLE :Retrieving Group Names from a MM Viewer Title PRODUCT :Miscellaneous Software Development Kits PROD/VER::2.0 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Multimedia Viewer Publishing Toolkit, version 2.0 ------------------------------------------------------------------------------- SUMMARY ======= The names and titles of the groups in a Multimedia Viewer version 2.0 title can be retrieved by using the Viewer function TitleGetInfo() with a value of 13 for the iInfoMsg parameter. The lParam2 parameter for TitleGetInfo() should be a far pointer to a text buffer to receive the group name and title. TitleGetInfo() writes a string of the form .grp"" to this buffer. The LOWORD of lParam1 should specify the maximum number of characters to copy into the buffer supplied in lParam2, including the NULL terminator. The HIWORD of lParam1 should be the number of the group whose name and title should be retrieved. The groups in a title are numbered consecutively, starting at 0. TitleGetInfo() returns -1 if it is passed a group number that does not exist in the title. The following code loops through the groups in a title, and displays a message box with the contents of the buffer returned from TitleGetInfo(): #define MAXBUF 255 int icount; char szBuf[MAXBUF]; HANDLE hTitle; hTitle=TitleOpen("test"); icount=0; while (TitleGetInfo(hTitle,13,MAKELONG(MAXBUF,icount), (LONG)(LPSTR)szBuf)!=-1L) { MessageBox(NULL,szBuf,"Groups",MB_OK); icount++; } Additional query words: 2.00 ====================================================================== Keywords : Technology : kbHomeProdSearch kbHomeMMsearch kbMMViewer200 Version : :2.0 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
