is there any other way using SysAppLaunch?
I use the code like that
{
UInt cardNo;
LocalID dbID;
DmSearchStateType searchInfo;
Err err;
DWord appLaunchResult;
Ptr cmdPBP;
err = DmGetNextDatabaseByTypeCreator (true, &searchInfo, 'appl','clee',
true, &cardNo, &dbID);
cmdPBP=MemPtrNew(100);
SysAppLaunch( cardNo, dbID,
sysAppLaunchFlagNewStack |
sysAppLaunchFlagNewGlobals ,
sysAppLaunchCmdNormalLaunch,
cmdPBP, &appLaunchResult );
MemPtrFree(cmdPBP);
}
SysAppLaunch can launch cllee, however , it cannot return back to my caller
program. just show a blank page. I have check the form
that is not my caller form.
