sharepoint 2010 - Event Receiver not affecting until refesh the list -


i have sharepoint 2010 list. have written event receiver code update field value in item added event. getting correct result, it's not updating field value until refresh list. why?

code:

public override void itemadded(spitemeventproperties properties)        {        base.itemadded(properties);         spweb web = properties.openweb();        splist list = properties.list;        int highestvalue = 0;         spquery query = new spquery();        query.query = @"<orderby>                          <fieldref name='nextno' ascending='false' />                      </orderby><rowlimit>1</rowlimit>";         splistitemcollection itemcollection = list.getitems(query);        if (itemcollection.count > 0)        {            splistitem item = itemcollection[0];            highestvalue = convert.toint32(item["nextno"]);        }         splistitem curritem = properties.listitem;        curritem["nextno"] = highestvalue + 1;        curritem.update(); }

you need use itemadding event receiver fires before list updated , show changes. itemadded event fires after list has been updated hence need refresh.

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)...
