c# - ling sql group with join -


i have linq sql query:

var orderitems =     orderitem in order_productitems     //join style in products_styles on orderitem.style equals style.index     orderitem.salesorderid == 123     group orderitem orderitem.frameno grp     select new     {         frameno = grp.key,         count = grp.select(x => x.frameno).count(),         totalcost = grp.sum(x=>x.costprice),         overallwidth = grp.single(x=>x.hardwaretype==3).overallheight,         //name = style.name,          //imagepath = style.external_image_path     };

i'm trying data product_styles tag along, it's not working...

the above works, not when uncomment bits above....

include style in group, reference orderitem , style in select:

var orderitems =     (from orderitem in order_productitems      join style in products_styles on orderitem.style equals style.index      orderitem.salesorderid == 123      group new { orderitem, style } orderitem.frameno grp      select new      {          frameno = grp.key,          count = grp.select(x => x.orderitem.frameno).count(),          totalcost = grp.sum(x => x.orderitem.costprice),          overallwidth = grp.single(x => x.orderitem.hardwaretype == 3).overallheight,          name = grp.select(x => x.style.name).first(),          imagepath = grp.select(x => x.style.external_image_path).first()       };

you may have adjust suit needs, , may not compile as-is since don't have environment set test in, should give general idea.

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)...
