I wanted to ask if it is possible, that if I have an older version of a product I authored in InstallShield's InstallScript type project that is installed on a customer machine, then I release an updated version of that product using InstallShield Basic MSI, can I make the new version detect it and do an upgrade? I was thinking that, from the MSI package, I could detect itand use a custom action to copy any required registry settings and files needed before calling the uninstaller for the older product, then install the new product. Is this even possible? I am pretty new to MSI, and have made much progress recently, but we need a way to move our customers off of the old installers and get them into the new ones. Any help is GREATLY appreciated. Thanks. ... View more

I needed a custom dialog that only would allow the user to choose the hard drives with which to install our products to. Currently, there is no such animal. I copied the SdAskDestPath code, and created a new function in my main script, called SdAskDestDrive. Here is the code to make it work. You need to go edit the standard SdAskDestPath. Just delete the text box where the path shows up and put in a combobox. make sure to note it's ID in the properties pane. //--------------------------------------------------------------------------- // function NUMBER SdAskDestDrive(szTitle, szMsg, svDir, nStyle) // Returns: NUMBER // Desc: Custom Dialog to ask for only a drive to install product to. //--------------------------------------------------------------------------- function NUMBER SdAskDestDrive(szTitle, szMsg, svDir, nStyle) string szDlg, svDirLoc, szTemp, svDrive; number nId, nTemp, nSdDialog; HWND hwndDlg; BOOL bDone; LIST listDrives; begin szDlg = "SdAskDestDrive"; nSdDialog = SD_NDLG_ASKDESTPATH; svDirLoc = svDir; // record data produced by this dialog if(MODE=SILENTMODE) then SdMakeName( szAppKey, szDlg, szTitle, nSdAskDestPath ); SilentReadData( szAppKey, "Result", DATA_NUMBER, szTemp, nId ); if((nId != BACK) && (nId != CANCEL)) then SilentReadData( szAppKey, "szDir", DATA_STRING, svDir, nTemp ); endif; return nId; endif; // ensure general initialization is complete if(!bSdInit) then SdInit(); endif; if(EzDefineDialog( szDlg, "", "", SD_NDLG_ASKDESTPATH ) = DLG_ERR) then return -1; endif; // Loop in dialog until the user selects a standard button bDone = FALSE; while (!bDone) nId = WaitOnDialog( szDlg ); switch (nId) case DLG_INIT: listDrives = ListCreate(STRINGLIST); GetValidDrivesList(listDrives, FIXED_DRIVE, -1); CtrlSetList(szDlg, DRIVECOMBO, listDrives); ListGetFirstString (listDrives, svDrive); CtrlSetCurSel(szDlg,DRIVECOMBO, svDrive); // CtrlSetText( szDlg, 0x80000000 | SD_STA_DESTDIR, svDrive); if(szMsg != "") then SdSetStatic( szDlg, SD_STA_CHANGEDIRMSG, szMsg ); endif; hwndDlg = CmdGetHwndDlg( szDlg ); SdGeneralInit( szDlg, hwndDlg, nStyle, szSdProduct ); SdSetDlgTitle(szDlg, hwndDlg, szTitle); case SD_PBUT_CHANGEDIR: // // Only "create" the folder if this is not ISMSI embedded. // SelectDirNoLog( "", "", svDirLoc, !INSTALLSCRIPTMSIEEUI ); case SD_PBUT_CONTINUE: svDir = sDrive; nId = NEXT; bDone = TRUE; case BACK: nId = BACK; bDone = TRUE; case DLG_ERR: SdError( -1, "SdAskDestDrive" ); nId = -1; bDone = TRUE; case DLG_CLOSE: SdCloseDlg( hwndDlg, nId, bDone ); default: CtrlGetCurSel(szDlg,DRIVECOMBO, svDrive); // CtrlSetText( szDlg, 0x80000000 | SD_STA_DESTDIR, svDrive ); // check standard handling if(SdIsStdButton( nId ) && SdDoStdButton( nId )) then bDone = TRUE; endif; endswitch; endwhile; // Cleanup Dialog EndDialog( szDlg ); ReleaseDialog( szDlg ); SdUnInit(); // record data produced by this dialog if(MODE=RECORDMODE) then SdMakeName( szAppKey, szDlg, szTitle, nSdAskDestPath ); SilentWriteData( szAppKey, "szDir", DATA_STRING, svDir, 0 ); SilentWriteData( szAppKey, "Result", DATA_NUMBER, "", nId ); endif; return nId; end; ...
