in mvc5 identity 2 signinmanager.passwordsigninasync take user name login. var result = await signinmanager.passwordsigninasync(model.email, model.password, model.rememberme, shouldlockout: false); but user name , email not same. want email address login.so how can that? thanks get user usermanager email. var user = usermanager.findbyemail(email); then use signinmanager's passwordsigninasync user's username var result = await signinmanager .passwordsigninasync(user.username,password,ispersistent,shouldlockout); or inside signinmanager add method ( asp.net identity discussion ) public async task<signinstatus> passwordemailsigninasync(string email, string password, bool ispersistent, bool shouldlockout) { var user = usermanager.findbyemail(email); return await passwordsigninasync(user.username,password,ispersistent,shouldlockout); } then use same passwordsigninasync user email instead of usermane.

i pretty new in delphi xe7, got project , tried build it, gives error like undeclared identifier 'images' in line..

there indexes available each columns. ex: indx1 on col1 , indx2 on col2. possible create again composite index indx3 combining col1 , col2? col1 , col2 used in condition. indx3 in effect? yes, query optimizer best matching index. if include col1 , col2 in composite index , query ( where ) 2 fields use index. you should consider throwing away index on col1 because composite index can used queries on col1 too. depends on sequence of columns in composite index: first column can queried without second one.

i created uiview in storyboard centered in center of view controller auto layout, , working fine across different device sizes. call largerview . however, programmatically create smaller uiview called smallerview , center view smallerview.center = largerview.center . i running issue given auto layout used on largerview , whenever use method above, smallerview never centers largerview.center . noticed take center coordinates of largerview appear in storyboard, based on specific layout of device using (in case, previous iphone 5's dimensions), not updated center affected auto layout. a similar issue may discussed here, except based on swift. know how constraints created programmatically, unsure how "refreshed" coordinates of view after auto layout applied. thanks! you need override following method in view controller: - (void)viewdidlayoutsubviews { [super viewdidlayoutsubviews]; self.smallview.frame.center = self.largeview.frame.cent

i have read many sites , decided ask question on stackoverflow, question pretty basic what .classpath file? file related java project or eclipse? some people think file related eclipse , thinks related project? .class files related java. you write code in java, compiled javac bytecode. bytecode store in .class files, , further interpreted java virtual machine (jvm). about classpath on wikipedia: similar classic dynamic loading behavior, when executing java programs, java virtual machine finds , loads classes lazily (it loads bytecode of class when class first used). classpath tells java in filesystem files defining these classes. so classpath mechanism related java, , handled eclipse thank .classpath file. hope :)

i need create following pattern: it homework, question failed first time. read should have used "*" 1 time, how work in case? appreciate if give me insight in how think. my code down below: using system; class starpattern { public static void main() { (int = 0; < 5; i++) { console.write("*"); } (int = 0; <= 0; a++) { console.writeline(""); console.write("*"); } (int c = 0; c <= 0; c++) { console.writeline(" *"); } (int d = 0; d <= 1; d++ ) { console.write("*"); console.writeline(" *"); } (int e = 0; e < 5; e++ ) { console.write("*"); } console.readline(); } } you can simplify code nesting loops outer ( i ) = rows , inner ( j ) = col

public observablecollection<model.childcommand> childcommands { get; private set; } childcommands bound datagrid. both segments show me items in datagrid. but in segment 1 datagrid items doesn't refresh automatically when collection changes. segment two, refresh works. segment 1: var childs = child in m_context.childcommand.local select child; this.childcommands = new observablecollection<model.childcommand>(childs); segment 2: this.childcommands = m_context.childcommand.local; how automatic refresh using segment one? the reason segment 1 not updating automatically end binding different observablecollection instance. when m_context.childcommand.local changes, segment 2 datagrid gets notified because bound observable collection instance. segment 1 datagrid bound different observable collection instance (that create when new observablecollection(childs). if want both of them bound m_context.childcommand.local obs

will both statements return same results? the top code has join in clause , takes on 4 hrs run. moving join outside same query runs in 1m 6s. have not seen join in clause. note dsa.doc_id child version record of orders.folder. --old code taking 4+ hrs run select top 1 status_to_date dsa (status_to = 'ca') , left(dsa.doc_id,12) = orders.folder --new code taking less minute select top 1 status_to_date dsa left outer join orders on left(dsa.doc_id,12) = orders.folder (status_to = 'ca') yes believe both queries give same result. , in side join gives slowest result. there 1 more alternate of above query willl nmore , more faster second query too select top (1) status_to_date dsa (status_to = 'ca') , (select count(*) orders orders.folder = left(dsa.doc_id,12)) > 0
