在Setup.rul中，新增OnBegin函數(shù)

STRING str1,spath,szApplicationPath,szApplicationCmdLine,szCmdLine;
function OnBegin()?? ?
begin
?? ?// TO DO: you may change default non-UI setting, for example
?? ?//
?? ?// You may also perform your custom initialization steps, check requirements, etc. ?
?? ?Disable(BACKBUTTON);
?? ?if(!MAINTENANCE)then
?? ?SdLicense2("License","","",SUPPORTDIR^"協(xié)議.txt",FALSE);
?? ?endif;??????? ?

?? ?//------------------------------------------------------------------------------------
?? ?szApplicationPath = WINSYSDIR ^ "msiexec.exe";
?? ?szApplicationCmdLine = "/i c:\\mysql.msi";
?? ?LongPathToQuote( szApplicationPath, TRUE );
?? ?szCmdLine = szApplicationPath + " " + szApplicationCmdLine;

??? RegDBSetDefaultRoot(HKEY_LOCAL_MACHINE);
??? MessageBox ("You are here", INFORMATION);
if(RegDBKeyExist("SOFTWARE\\MySQL AB\\MySQL Connector/ODBC 5.2 64bit(community edition)")<0)then?? ?
?? ?MessageBox ("You are here1", INFORMATION);
?? ?MessageBox(PROGRAM,INFORMATION); ?
?? ?MessageBox(SRCDIR,INFORMATION); ?
?? ?MessageBox(szCmdLine,INFORMATION);
?? ?LaunchAppAndWait("",szCmdLine, LAAW_OPTION_WAIT);
endif;


end;功能：在安裝時，出現(xiàn)許可證后檢測是否系統(tǒng)中安裝必要的組件，如果沒有安裝就提示安裝。有，則跳過。當必要組件是.exe的文件。直接加載到support中即可。如果是.msi后綴的文件需要調(diào)用window installer來安裝。用到的函數(shù)是LaunchAppAndWait(szProgram, szCmdLine, nOptions )

szProgram:Specifies the complete path and file name of the application to be launched.

szCmdLine:Specifies the command-line parameters to pass to the launched application.

nOptions:LAAW_OPTION_WAIT----Passed through the function to WaitForApplication.
