Nhibernate 'Not all named parameters have been set' when using spatial query -


this query 

var selectdinnerbydistance = string.format(             @"select                  u.profileimageurl profileimageurl,                  d.starter starter,                 d.main main,                 d.dessert dessert,                 d.dry drydinner,                 d.[date] eventdate,                 l.geoloc.stdistance(geography::stgeomfromtext('point({0} {1})', 4326)) distance                 dbo.locations l                 join dinners d on d.locationid = l.id                 join users u on u.id = d.userid                 order distance asc                 offset {2} rows                 fetch next {3} rows only"             , lat, lng, skip, take); var output = _session      .createsqlquery(selectdinnerbydistance)      .setresulttransformer(transformers.aliastobean<dinnerlistitemdto>())      .list<dinnerlistitemdto>();

and exception i'm getting is

not named parameters have been set: [':stgeomfromtext']

the query works fine in management studio. there way should using straight sql queries avoid error?

thanks

as stated in comments above. solution rewrite query in different way replaced "geography::stgeomfromtext" 

l.geoloc.stdistance(@dist.stbuffer(0.2).stastext()) distance

and placed following @ top of query 

declare @dist geography = 'point({0} {1})'

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
